What is it about September?

. . . often a mellow month, the transition from the hot, summer months to the cooler days of autumn.

When we worked overseas during the 1970s we would return to the UK each September on home-leave. And mostly enjoyed excellent weather.

I think September Song, that classic from 1938 and performed here by Jeff Lynne on his 1990 album Armchair Theatre, sums up the month just right.

September is also a Jackson birthday month. My father, Fred Jackson, was born on 15 September 1908. My eldest brother Martin and youngest grandson Felix share a birthday, 1 September, but 74 years apart, being 81 and seven respectively this year. And second grandson Elvis celebrates his birthday on 24 September. He will be nine.

It’s also a month when significant things happened during my career.

Fifty years ago, in September 1970, I enrolled at the University of Birmingham for the one year MSc degree course in Conservation and Utilization of Plant Genetic Resources run by the Department of Botany in the School of Biological Sciences. I had been in the university just once before, in the early summer of 1967, when I sat my Biology Advanced Level practical exam in the School’s first year laboratory, never anticipating I would be there again to study three years later.

A year later, in September 1971 I had expected to be on my way to Peru in South America, to join the International Potato Center (CIP) on a one-year contract to help manage the center’s potato germplasm collection. That didn’t happen then, but took until January 1973 before I departed these shores.

In September 1980, while winding down my five year assignment in Costa Rica, I heard about a lectureship that had just been advertised in the Department of Plant Biology (formerly Botany) at Birmingham. I sent in my application and successfully interviewed for the position in January 1981, joining the faculty in April.

Moving on a decade, it was during September 1990 that I first heard about a new position at the International Rice Research Institute (IRRI) in the Philippines as Head of the newly-created Genetic Resources Center. I was interviewed in January 1991 and joined the institute in July that year remaining there for almost 19 years before retiring in April 2010.


It’s now 2020. So what does September hold in store? Hopefully, it will be the month our house sale is completed and we move north to Newcastle upon Tyne.

The quiet man of GRC

GRC? It’s short for the TT Chang Genetic Resources Center at the International Rice Research Institute (IRRI) in the Philippines, which I had the privilege to lead between July 1991 and April 2001. I’m not sure if GRC is an organizational unit at IRRI anymore having just checked IRRI’s organizational structure dated April 2020.

However, GRC is/was the home of the International Rice Genebank at IRRI, the largest of its kind globally for rice. It safely conserves more than 130,000 samples (known as accessions) of cultivated and wild rice species from around the world and, as the most genetically-diverse collection of rice anywhere, it is the foundation for food security in many countries, especially in Asia. Rice breeders have dipped into this valuable resource for almost six decades since IRRI was founded in 1960 and the first germplasm samples brought to Los Baños by my predecessor, Dr TT Chang.

Renato ‘Ato’ Reaño

Anyway, this post is not about me or Dr Chang, but about someone who surely was the quiet man of GRC. Who is this low-key individual?

Why, Renato Reaño of course, known to one and all as ‘Ato’.

Not long after I joined IRRI, it became clear to me that Ato should become my right-hand man for managing all the genebank field operations, from multiplication and rejuvenation of seed samples, as well as establishing and looking after field plots for germplasm characterization (although the actual scoring of the materials was the responsibility for a few years of another colleague, Tom Clemeno, who passed away in 2015).

So, once I’d made an analysis of how the genebank was being managed when I took the helm in 1991, and decided on changes I deemed necessary (not universally accepted by all genebank in the first instance after several decades of working under Dr Chang), I asked Ato to take on the role of Field Operations Manager (although at that time he was officially still only a Research Assistant).

Ato retired from IRRI in March this years after more than 36 years of loyal—and very productive—service to the institute. Over the years, and as his confidence grew, taking on more responsibilities, Ato was promoted to new levels in the IRRI hierarchy, and retired as a Senior Associate Scientist.

Along the way he was elected to lead the IRRI employees association (an excellent indication of the esteem in which his colleagues held him), and he was also elected President of the Crop Science Society of the Philippines (CSSP) for 2006-2007.


Ato helped develop and implement many necessary changes to field operations. What is often not fully appreciated that for the long-term conservation of seeds in a genebank, what happens in the field during the growing season and how seeds are handled through the drying process are as important—if not more so in some respects—than the actual storage conditions. Dr Fiona Hay, a seed physiologist who was hired after I’d passed the GRC baton to my successor Dr Ruaraidh Sackville Hamilton in 2002, studied how the drying of seeds could be improved further, and Ato’s role in managing the rice germplasm in the field and the drying after harvest was pivotal. I’ve written about those aspects of rice germplasm management in an August 2015 post.

Ato made the field operations look straightforward. Nothing could be further from the truth. He had to handle thousands of seed samples each planting season, nurturing each one, ensuring there were no mix-ups.

He had a great rapport with his staff. Here he is with some of them in 2017 after they had finished the harvest of more than 4000 samples, and dried them successfully using the new approach that I referred to in the August 2015 post above.

Each season (there being two in Los Baños, wet and dry) Ato took responsibility for growing thousands of seed samples, some for the first time after they had been acquired by the genebank, others for routine regeneration if seed viability had declined or seed stocks were running low, or for characterization of the different rices for a whole series of traits, such as days to flowering, plant height, color of grains, and the like.

But to have a better appreciation of Ato’s work in the field and how that contributed to the work of the genebank, just watch this segment, 2:04 – 4:29 minutes in the video below to see for yourselves.

Ato remained the quiet man of GRC during the years I was at the helm, but he constantly grew in confidence, taking his first overseas trip on behalf of the genebank to present a paper at ICRISAT in Hyderabad, India in 1995, and eventually being recognised by his peers and elected to the roles I mentioned earlier.

I also relied on Ato to help me interact with GRC staff. If I became aware of a staff ‘situation’ developing (perhaps an unease I could detect as I made my daily visits to every part of the genebank), it would have been difficult for me as Head of GRC, and as a non-Filipino who didn’t speak Tagalog, to easily get to the bottom of things. Then I would ask Ato to help find out what was going on, deal with it if he could, and only elevate issues to me that needed my intervention. This relationship worked well, and I was very grateful to Ato for the management support he provided in this respect.

Thanks for everything that you did, Ato. Your contributions to the long-term conservation of rice genetic resources will long be remembered and appreciated.

With Ato’s retirement, there’s just one of ‘my’ staff left. Genebank Manager Pola de Guzman will also retire later this year. It will finally be the end of the Chang-Jackson-Sackville Hamilton era.


 

You’ve got mail . . . maybe

Email. Something we take for granted. In these Covid-19 lockdown days, where would be without email to keep in touch with family and friends? In fact, for many, working from home without access to emails would not be an option.

And what about Facebook, Twitter, Instagram, WhatsApp, Zoom, and all the other messaging apps?

Bob Zeigler

Yet it’s not so long ago that none of us had access to any of these. How things have changed over the past 40 years, even just the last decade.

My former colleague and IRRI Director General Bob Zeigler often said that we were living through three revolutions: in telecommunications, computing, and molecular biology. It was the combination of these three that allowed scientists to collaborate world-wide in real time, using the ‘new’ computing power to handle the vast amounts of data that molecular biology was generating.

That wasn’t so . . . not so long ago.

When, in 1976, the Director General of the International Potato Center (CIP), Dr Richard Sawyer, asked me to set up a satellite research program in Costa Rica (at a regional center, CATIE, in Turrialba) the only ways we had to communicate with HQ in Lima were ‘snail mail’, telephone, or Telex. Even making a phone call was difficult. I had to book an international call to Peru at least a day ahead.

There were no personal computers. Even hand-held calculators were a novelty. I remember one scientist at CATIE, soil scientist Warren Forsythe, proudly showing off a newfangled—and basic—electronic calculator (addition, subtraction, division, multiplication functions only) that he’d recently spent more than USD400 on (that’s about USD1800 today!). They almost give them away nowadays. There’s more processing power in your basic smartphone than took the first astronauts to the Moon.

When I was an undergraduate at the University of Southampton in the late 1960s we used either logarithmic tables (log tables) or a hand-cranked calculating machine like the one shown below. I’m not sure if I remember nowadays how to use log tables. I never did master the slide rule.

The first computer I ever saw was at a major steelworks (Ravenscraig I think it was, at Motherwell, just south of Glasgow) where my eldest brother Martin was a computer engineer. He took me along one afternoon when he had access to the computer (an ICL mainframe if memory serves me right) for routine maintenance.

He showed me how paper tapes were used to run routines. Paper tape? I can’t remember the last time I saw that.

Completing an honours ecology project for my undergraduate dissertation in 1970, I used the university’s mainframe computer to complete a type of vegetation analysis known as Association Analysis.  Ecologist Joyce Lambert was my supervisor, and she and former head of the Department of Botany, Professor Bill Williams, were pioneers in the use of computers and quantitative methods in ecology [1]. I encoded my data on punched cards, with the help of one of the graduate students, John Barr (studying for a PhD in numerical taxonomy).

When I moved to Birmingham in 1970 (to study for the one year MSc course on plant genetic resources) there was a short module on data management, taught by Brian Kershaw, a programmer in the university’s Computer Centre. He developed the computer programs to sort and collate data, and print maps, for A Computer-Mapped Flora: A Study of The County of Warwickshire [2] published in 1971, and the first of its kind. His MSc module was more about basic programming than data management per se and not, in my opinion, very helpful, or enlightening. Things changed once we had access to personal computers over a decade later.

IBM launched its first personal computer (PC) in August 1981, just a few months after I had returned to the UK and joined the faculty of the University of Birmingham. My memory is fuzzy. We must have had one of these in our lab in the Department of Plant Biology (School of Biological Sciences). I can remember that we used 5¼ inch floppy disks, but also installed an 8 inch disk reader. MS-DOS was the operating system.

It wasn’t until one of my colleagues, plant physiologist Dr Digby Idle secured a grant to purchase half a dozen Apple Macintosh computers that we had access to personal computers, mainly for teaching. They certainly revolutionized the teaching of data management to MSc students by my colleague Dr Brian Ford-Lloyd.

Staff were sometimes allowed to take a machine home for weekend. My young daughters Hannah and Philippa had great fun exploring a couple of the games (rudimentary by today’s standards) that came with each computer.

Personal computing really took off, however, once Alan Sugar released the first IBM clones under the Amstrad brand in the 1980s. I bought several machines for my lab. We were still using the university’s mainframe computer for analysis of large data sets. It wasn’t until the end of the 1980s that PCs began to have the power to carry out some of these same analyses.

I even purchased an Amstrad for home use. It had twin 5¼ inch floppy disk drives, each with a capacity of about 500 Kb if I’m not mistaken. But then I installed a 32 MB hard drive, and then we were really cooking! There was no internet of course, and no WiFi. But connected to a dot matrix printer (are they around any more?), and using a word processing package called PFS First Choice. By today’s standards it wasn’t sophisticated at all, but it was convenient for home use [3].

We even took that Amstrad to the Philippines in 1991 and used it for a couple of years. I found it at the back of a cupboard 19 years later when we were packing to return to the UK.

But I digress. Back to emails.

I don’t really remember when we started to use email in a rather simple way at the university during the 1980s. Even after I had moved to IRRI in July 1991 I had to ‘fight’ to have a PC on my desk. Again I’m not certain when email was routinely used at the institute.

But by the time I had moved from the Genetic Resources Center to become Director for Program Planning and Communications (DPPC) in May 2001, email was well established as the most convenient and regularly used method of communication among staff at IRRI, and with external collaborators and donors. In fact, as I set up the DPPC Office much of what we achieved was based on a systematic use and filing of emails in lieu of communication through hard copies.

I’m the sort of person who attends to all incoming correspondence—memos, letters, emails—more or less straight away, deciding whether to respond immediately or taking a decision to put that to one side for a response later on. At the very least, I tried to send an acknowledgment that someone’s communication has been received. Being in a senior management position, I felt it was really important to keep on top of emails and the like, because without a response, the sender might not be able to move ahead without a decision from me. Even if that meant working through 10s if not 100s of emails a day. I never liked the grass to grow beneath my feet, so to speak.

But communication by email was both a blessing and a curse as far as project management was concerned. Because emails could be sent instantaneously, more or less, it was possible to send off project reports, or even funding requests, right up to any deadline, not having to prepare several weeks ahead for ‘snail mail’ delivery.

However, the use of emails also made some donors (like USAID, for example) somewhat dysfunctional. Knowing that we would be able to send replies in by email, they would often make demands of us for information, reports, or whatever, just before their deadline, without understanding that we also needed appropriate lead time to compile and prepare the information requested. The transmission by email was just a bonus.

But there’s no doubt that how we used email in DPPC, straight to our donor contacts, greatly enhanced fund-raising capability at IRRI.

I still look forward to receiving emails from family and friends. For many years I have used Fastmail as my platform of choice, although I do keep a Gmail address as a backup. And, for most of my continuing business and utility contacts, emails are the preferred method of communication. It’s always a pleasure when an unexpected email drops into my mailbox especially from someone I haven’t heard from for some time.

Yes, I’ve got mail . . .

It was generally replaced by WordPerfect, a package I never got to grips with. I became really quite proficient in the use of WordStar. Who can forget all those formatting tools for bold, underlining, and italics, etc?

 

Potatoes or rice?

I graduated in July 1970 from the University of Southampton (a university on England’s south coast) with a BSc Hons degree in botany and geography. ‘Environmental botany’ actually, whatever that meant. The powers that be changed the degree title half way through my final (i.e. senior) year.

Anyway, there I was with my degree, and not sure what the future held in store. It was however the beginning of a fruitful 40 year career in international agricultural research and academia at three institutions over three continents, in a number of roles: research scientist, principal investigator (PI), program leader, teacher, and senior research manager, working primarily on potatoes (Solanum tuberosum) and rice (Oryza sativa), with diversions into some legume species such as the grasspea, an edible form of Lathyrus.

Potatoes on the lower slopes of the Irazu volcano in Costa Rica, and rice in Bhutan

I spent the 1970s in South and Central America with the International Potato Center (CIP), the 1980s at the University of Birmingham as a Lecturer in the School of Biological Sciences (Plant Biology), and almost 19 years from July 1991 (until my retirement on 30 April 2010) at the International Rice Research Institute (IRRI) in the Philippines¹.

I divided my research time during those 40 years more or less equally between potatoes and rice (not counting the legume ‘diversions’), and over a range of disciplines: biosystematics and pre-breeding, genetic conservation, crop agronomy and production, plant pathology, plant breeding, and biotechnology. I was a bit of a ‘jack-of-all-trades’, getting involved when and where needs must.

However, I haven’t been a ‘hands-on’ researcher since the late 1970s. At both Birmingham and IRRI, I had active research teams, with some working towards their MSc or PhD, others as full time researchers. You can see our research output over many years in this list of publications.

Richard Sawyer

Very early on in my career I became involved in research management at one level or another. Having completed my PhD at Birmingham in December 1975 (and just turned 27), CIP’s Director General Richard Sawyer asked me to set up a research program in Costa Rica. I moved there in April 1976 and stayed there until November 1980.


In these Covid-19 lockdown days, I’m having ample time to reflect on times past. And today, 30 April, it’s exactly 10 years since I retired.

Just recently there was a Twitter exchange between some of my friends about the focus of their research, and the species they had most enjoyed working on.

And that got me thinking. If I had to choose between potatoes and rice, which one would it be? A hard decision. Even harder, perhaps, is the role I most enjoyed (or gave me the most satisfaction) or, from another perspective, in which I felt I’d accomplished most. I’m not even going to hazard a comparison between living and working in Peru (and Costa Rica) versus the Philippines. However, Peru has the majesty of its mountain landscapes and its incredible cultural history and archaeological record (notwithstanding I’d had an ambition from a small boy to visit Peru one day). Costa Rica has its incredible natural world, a real biodiversity hotspot, especially for the brilliant bird life. And the Philippines I’ll always remember for all wonderful, smiling faces of hard-working Filipinos.

And the scuba diving, of course.

Anyway, back to potatoes and rice. Both are vitally important for world food security. The potato is, by far, the world’s most important ‘root’ crop (it’s actually a tuber, a modified underground stem), by tonnage at least, and grown worldwide. Rice is the world’s most important crop. Period! Most rice is grown and consumed in Asia. It feeds more people on a daily basis, half the world’s population, than any other staple. Nothing comes close, except wheat or maize perhaps, but much of those grains is processed into other products (bread and pasta) or fed to animals. Rice is consumed directly as the grain.


Just 24 when I joined CIP as a taxonomist in January 1973, one of my main responsibilities was to collect potato varieties in various parts of the Peruvian Andes to add to the growing germplasm collection of native varieties and wild species. I made three trips during my three years in Peru: in May 1973 to the departments of Ancash and La Libertad (with my colleague, Zósimo Huamán); in May 1974 to Cajamarca (accompanied by my driver Octavio); and in January/February 1974 to Cuyo-Cuyo in Puno and near Cuzco, with University of St Andrews lecturer, Dr Peter Gibbs.

Top: with Octavio in Cajamarca, checking potato varieties with a farmer. Bottom: ready for the field, near Cuzco.

My own biosystematics/pre-breeding PhD research on potatoes looked at the breeding relationships between cultivated forms with different chromosome numbers (multiples of 12) that don’t naturally intercross freely, as well as diversity within one form with 36 chromosomes, Solanum x chaucha. In the image below, some of that diversity is shown, as well as examples of how we made crosses (pollinations) between different varieties, using the so-called ‘cut stem method’ in bottles.

Several PhD students of mine at Birmingham studied resistance to pests and diseases in the myriad of more than 100 wild species of potato that are found from the southern USA to southern Chile. We even looked at the possibility of protoplast fusion (essentially fusion of ‘naked’ cells) between different species, but not successfully.

I developed a range of biosystematics projects when taking over leadership of the International Rice Genebank at IRRI, publishing extensively about the relationships among the handful (about 20 or so) wild rice species and cultivated rice. One of the genebank staff, Elizabeth Ma. ‘Yvette’ Naredo (pointing in the image below) completed her MS degree under my supervision.

Although this research had a ‘taxonomic’ focus in one sense (figuring out the limits of species to one another), it also had the practical focus of demonstrating how easily species might be used in plant breeding, according to their breeding relationships, based on the genepool concept of Harlan and de Wet, 1971 [1], illustrated diagrammatically below.


When I transferred to Costa Rica in 1976, I was asked to look into the possibility of growing potatoes under hot, humid conditions. At that time CIP was looking to expand potato production into areas and regions not normally associated with potato cultivation. One of the things I did learn was how to grow a crop of potatoes.

I was based in Turrialba (at the regional institute CATIE), at around 650 masl, with an average temperature of around 23°C (as high as 30°C and never much lower than about 15°C; annual rainfall averages more than 2800 mm). Although we did identify several varieties that could thrive under these conditions, particularly during the cooler months of the year, we actually faced a more insidious problem, and one that kept me busy throughout my time in Costa Rica.

Shortly after we planted the first field trials on CATIE’s experiment station, we noticed that some plants were showing signs of wilting but we didn’t know the cause.

With my research assistant Jorge Aguilar checking on wilted plants in one of the field trials.

Luis Carlos González

Fortunately, I established a very good relationship with Dr Luis Carlos González Umaña, a plant pathologist in the University of Costa Rica, who quickly identified the culprit: a bacterium then known as Pseudomonas solanacearum (now Ralstonia solanacearum) that causes the disease known as bacterial wilt.

I spent over three years looking into several ways of controlling bacterial wilt that affects potato production in many parts of the world. An account of that work was one of the first posts I published in this blog way back in 2012.

The other aspect of potato production which gave me great satisfaction is the work that my colleague and dear friend Jim Bryan and I did on rapid multiplication systems for seed potatoes.

Being a vegetatively-propagated crop, potatoes are affected by many diseases. Beginning with healthy stock is essential. The multiplication rate with potatoes is low compared to crops that reproduce through seeds, like rice and wheat. In order to bulk up varieties quickly, we developed a set of multiplication techniques that have revolutionised potato seed production systems ever since around the world.

AS CIP’s Regional Representative for Mexico, Central America, and the Caribbean (known as CIP’s Region II), I also contributed to various potato production training courses held each year in Mexico. But one of our signature achievements was the launch of a six nation research network or consortium in 1978, known as PRECODEPA (Programa REgional COoperativo DE PApa), one of the first among the CGIAR centers. It was funded by the Swiss Government.

Shortly after I left Costa Rica in November 1980, heading back to Lima (and unsure where my next posting would be) PRECODEPA was well-established, and leadership was assumed by the head of one of the national potato program members of the network. PRECODEPA expanded to include more countries in the region (in Spanish, French, and English), and was supported continually by the Swiss for more than 25 years. I have written here about how PRECODEPA was founded and what it achieved in the early years.

I resigned from CIP in March 1981 and returned to the UK, spending a decade teaching at the University of Birmingham.


Did I enjoy my time at Birmingham? I have mixed feelings.

I had quite a heavy teaching load, and took on several administrative roles, becoming Chair of the Biological Sciences Second Year Common Course (to which I contributed a module of about six lectures on agricultural ecosystems). I had no first teaching commitments whatsoever, thank goodness. I taught a second year module with my colleague Richard Lester on flowering plant taxonomy, contributing lectures about understanding species relationships through experimentation.

Brian Ford-Lloyd

With my close friend and colleague Dr Brian Ford-Lloyd (later Professor), I taught a final year module on plant genetic resources, the most enjoyable component of my undergraduate teaching.

One aspect of my undergraduate responsibilities that I really did enjoy (and took seriously, I believe—and recently confirmed by a former tutee!) was the role of personal tutor to 1st, 2nd and 3rd year students. I would meet with them about once a week to discuss their work, give advice, set assignments, and generally be a sounding board for any issues they wanted to raise with me. My door was always open.

Most of my teaching—on crop diversity and evolution, germplasm collecting, agricultural systems, among others—was a contribution to the one year (and international) MSc Course on Conservation and Utilization of Plant Genetic Resources on which I had studied a decade earlier. In my travels around the world after I joined IRRI in 1991, I would often bump into my former students, and several also contributed to a major rice biodiversity project that I managed for five years from 1995. I’m still in contact with some of those students, some of whom have found me through this blog. And I’m still in contact with two of my classmates from 1970-71.

Research on potatoes during the 1980s at Birmingham was not straightforward. On the one hand I would have liked to continue the work on wild species that had been the focus of Professor Jack Hawkes’ research over many decades.

With Jack Hawkes, collecting Solanum multidissectum in the central Andes north of Lima in early 1981 just before I left CIP to return to the UK. This was the only time I collected with Hawkes. What knowledge he had!

He had built up an important collection of wild species that he collected throughout the Americas. I was unable to attract much funding to support any research projects. It wasn’t a research council priority. Furthermore, there were restrictions on how we could grow these species, because of strict quarantine regulations. In the end I decided that the Hawkes Collection would be better housed in Scotland at the Commonwealth Potato Collection (or CPC, that had been set up after the Empire Potato Collecting Expedition in 1938-39 in which Jack participated). In 1987, the Hawkes Collection was acquired by the CPC and remains there to this day.

Dave Downing was the department technician who looked after the potato collection at Birmingham. He did a great job coaxing many different species to flower.

Having said that, one MSc student, Susan Juned, investigated morphological and enzyme diversity in the wild species Solanum chacoense. After graduating Susan joined another project on potato somaclones that was managed by myself and Brian Ford-Lloyd (see below). Another student, Ian Gubb, continued our work on the lack of enzymic blackening in Solanum hjertingii, a species from Mexico, in collaboration with the Food Research Institute in Norwich, where he grew his research materials under special quarantine licence. A couple of Peruvian students completed their degrees while working at CIP, so I had the opportunity of visiting CIP a couple of times while each was doing field work, and renew my contacts with former colleagues. In 1988, I was asked by CIP to join a panel for a three week review of a major seed production project at several locations around Peru.

With funding of the UK’s Overseas Development Administration (ODA, or whatever it was then), and now the Department for International Development (DFID), and in collaboration with the Plant Breeding Institute (PBI) in Cambridge and CIP, in 1983/84 we began an ambitious (and ultimately unsuccessful) project on true potato seed (TPS) using single seed descent (SSD) in diploid potatoes (having 24 chromosomes). Because of the potato quarantine situation at Birmingham, we established this TPS project at PBI, and over the first three years made sufficient progress for ODA to renew our grant for a second three year period.

We hit two snags, one biological, the other administrative/financial that led to us closing the project after five years. On reflection I also regret hiring the researcher we did. I’ve not had the same recruitment problem since.

Working with diploid potatoes was always going to be a challenge. They are self incompatible, meaning that the pollen from a flower ‘cannot’ fertilize the same flower. Nowadays mutant forms have been developed that overcome this incompatibility and it would be possible to undertake SSD as we envisaged. Eventually we hit a biological brick wall, and we decided the effort to pursue our goal would take more resources than we could muster. In addition, the PBI was privatized in 1987 and we had to relocate the project to Birmingham (another reason for handing over the Hawkes Collection to the CPC). We lost valuable research impetus in that move, building new facilities and the like. I think it was the right decision to pull the plug when we did, admit our lack of success, and move on.

We wrote about the philosophy and aims of this TPS project in 1984 [2], but I don’t have a copy of that publication. Later, in 1987, I wrote this review of TPS breeding [3].

Susan Juned

As I mentioned above, Brian Ford-Lloyd and I received a commercial grant to look into producing tissue-culture induced variants, or somaclones, of the crisping potato variety Record with reduced low temperature sweetening that leads to ‘blackened’ crisps (or chips in the USA) on frying. We hired Susan Juned as the researcher, and she eventually received her PhD in 1994 for this work. Since we kept the identity of each separate Record tuber from the outset of the project, over 150 tubers, and all the somaclone lines derived from each, we also showed that there were consequences for potato seed production and maintenance of healthy stocks as tissue cultures. We published that work in 1991. We also produced a few promising lines of Record for our commercial sponsor.

One funny aspect to this project is that we made it on to Page 3 of the tabloid newspaper The Sun, notorious in those days for a daily image of a well-endowed and naked young lady. Some journalist or other picked up a short research note in a university bulletin, and published an extremely short paragraph at the bottom of Page 3 (Crunch time for boffins) as if our project did not have a serious objective. In fact, I was even invited to go on the BBC breakfast show before I explained that the project had a serious objective. We weren’t just investigating ‘black bits in crisp packets’.

Brian and I (with a colleague, Martin Parry, in the Department of Geography) organized a workshop on climate change in 1989, when there was still a great deal of skepticism. We published a book in 1990 from that meeting (and followed up in 2013 with another).

Despite some successes while at Birmingham, and about to be promoted to Senior Lecturer, I had started to become disillusioned with academic life by the end of the 1980s, and began to look for new opportunities. That’s when I heard about a new position at IRRI in the Philippines: Head of the newly-established Genetic Resources Center, with responsibility for the world renowned and largest international rice genebank. I applied. The rest is history,


Klaus Lampe

I was appointed by Director General Klaus Lampe even though I’d never actually run a genebank before. Taking on a genebank as prestigious as the International Rice Genebank was rather daunting. But help was on the way.

I knew I had a good team of staff. All they needed was better direction to run a genebank efficiently, and bring the genebank’s operations up to a higher standard.

There was hardly an aspect of the operations that we didn’t overhaul. Not that I had the genebank team on my side from the outset. It took a few months for them to appreciate that my vision for the genebank was viable. Once on board, they took ownership of and responsibility for the individual operations while I kept an overview of the genebank’s operation as a whole.

I’ve written extensively in this blog about the genebank and genetic resources of rice, and in this post I gave an overview of what we achieved.

You can find more detailed stories of the issues we faced with data management and germplasm characterization, or seed conservation and regeneration (in collaboration with my good friend Professor Richard Ellis of the University of Reading). We also set about making sure that germplasm from around Asia (and Africa and the Americas) was safe in genebanks and duplicated in the International Rice Genebank. We embarked on an ambitious five year project (funded by the Swiss government) to collect rice varieties mainly (and some wild samples as well), thereby increasing the size of the genebank collection by more than 25% to around 100,000 samples or accessions. The work in Laos was particularly productive.

We did a lot of training in data management and germplasm collecting, and successfully studied how farmers manage rice varieties (for in situ or on farm conservation) in the Philippines, Vietnam, and India.

One of IRRI’s main donors is the UK government through DFID. In the early 1990s, not long after I joined IRRI, DFID launched a new initiative known as ‘Holdback’ through which some of the funding that would, under normal circumstances, have gone directly to IRRI and its sister CGIAR centers was held back to encourage collaboration between dneters and scientists in the UK.

Whenever I returned on annual home leave, I would spend some time in the lab at Birmingham. John Newbury is on the far left, Parminder Virk is third from left, and Brian Ford-Lloyd on the right (next to me). One of my GRC staff, the late Amy Juliano spent a couple of months at Birmingham learning new molecular techniques. She is on the front row, fourth from right.

With my former colleagues at the University of Birmingham (Brian Ford-Lloyd, Dr John  Newbury, and Dr Parminder Virk) and a group at the John Innes Centre in Norwich (the late Professor Mike Gale and Dr Glenn Bryan) we set about investigating how molecular markers (somewhat in their infancy back in the day) could be used describe diversity in the rice collection or identify duplicate accessions.

Not only was this successful, but we published some of the first research in plants showing the predictive value of molecular markers for quantitative traits. Dismissed at the time by some in the scientific community, the study of  associations between molecular markers and traits is now mainstream.

In January 1993, I was elected Chair while attending my first meeting of the Inter-Center Working Group on Genetic Resources (ICWG-GR) in Ethiopia (my first foray into Africa), a forum bringing expertise in genetic conservation together among the CGIAR centers.

ICWG-GR meeting held at ILCA in Addis Ababa, Ethiopia in January 1993.

Over the next three years while I was Chair, the ICWG-GR managed a review of genetic resources in the CGIAR, and a review of center genebanks. We also set up the System-Wide Genetic Resources Program, that has now become the Genebank Platform.


I never expected to remain at IRRI as long as I did, almost nineteen years. I thought maybe ten years at most, and towards the end of the 1990s I began to look around for other opportunities.

Then, in early 2001, my career took another course, and I left genetic resources behind, so to speak, and moved into senior management at IRRI as Director for Program Planning and Coordination (later Communications, DPPC). And I stayed in that role until retiring from the institute ten years ago.

Ron Cantrell

The Director General, Ron Cantrell, asked me to beef up IRRI’s resource mobilization and project management. IRRI’s reputation with its donors had slipped. It wasn’t reporting adequately, or on time, on the various projects funded at the institute. Furthermore, management was not sure just what projects were being funded, by which donor, for what period, and what commitments had been set at the beginning of each. What an indictment!

I wrote about how DPPC came into being in this blog post. One of the first tasks was to align information about projects across the institute, particularly with the Finance Office. It wasn’t rocket science. We just gave every project (from concept paper to completion) a unique ID that had to be used by everyone. We also developed a corporate brand for our project reporting so that any donor could immediately recognise a report from IRRI.

So we set about developing a comprehensive project management system, restoring IRRI’s reputation in less than a year, and helping to increase the annual budget to around US$60 million. We also took on a role in risk management, performance appraisal, and the development of IRRI’s Medium Term Plans and its Strategy.

Bob Zeigler

Then under Ron’s successor, Bob Zeigler, DPPC went from strength to strength. Looking back on it, I think those nine years in DPPC were the most productive and satisfying of my whole career. In that senior management role I’d finally found my niche. There’s no doubt that the success of DPPC was due to the great team I brought together, particularly Corinta who I plucked out of the research program where she was working as a soil chemist.

Around 2005, after Bob became the DG, I also took on line management responsibility for a number of support units: Communication and Publications Services (CPS), Library and Documentation Services (LDS), Information Technology Service (ITS), and the Development Office (DO). Corinta took over day-to-day management of IRRI’s project portfolio.

With my unit heads, L-R: Gene Hettel (CPS), Mila Ramos (LDS), Marco van den Berg (ITS), Duncan Macintosh (DO), and Corinta Guerta (DPPC).


So, ten years on, what memories I have to keep my mind ticking over during these quiet days. When I began this post (which has turned out much longer than I ever anticipated) my aim was to decide between potatoes and rice. Having worked my way through forty years of wonderful experiences, I find I cannot choose one over the other. There’s no doubt however that I made a greater contribution to research and development during my rice days.

Nevertheless, I can’t help thinking about my South American potato days with great affection, and knowing that, given the chance, I’d be back up in the Andes at a moment’s notice. Potatoes are part of me, in a way that rice never became.

Everyone needs good mentors. I hope I was a good mentor to the folks who worked with me. I was fortunate to have had great mentors. I’ve already mentioned a number of the people who had an influence on my career.

I can’t finish this overview of my forty years in international agriculture and academia without mentioning five others: Joe Smartt (University of Southampton); Trevor Williams (University of Birmingham); Roger Rowe (CIP); John Niederhauser (1990 World Food Prize Laureate); and Ken Brown (CIP)

L-R: Joe Smartt, Trevor Williams, Roger Rowe, and John Niederhauser.

  • Joe, a lecturer in genetics, encouraged me to apply for the MSc Course at Birmingham in early 1970. I guess without his encouragement (and Jack Hawkes accepting me on to the course) I never would have embarked on a career in genetic conservation and international agriculture. I kept in regular touch with Joe until he passed away in 2013.
  • At Birmingham, Trevor supervised my MSc dissertation on lentils. He was an inspirational teacher who went on to become the Director General of the International Board for Plant Genetic Resources (IBPGR) in Rome. The last time I spoke with Trevor was in 2012 when he phoned me one evening to congratulate me on being awarded an OBE. He passed away in 2015.
  • Roger joined CIP in July 1973 as Head of the Breeding and Genetics Department, from the USDA Potato Collection in Wisconsin. He was my first boss in the CGIAR, and I learnt a lot from him about research and project management. We are still in touch.
  • John was an eminent plant pathologist whose work on late blight of potatoes in Mexico led to important discoveries about the pathogen and the nature of resistance in wild potato species. John and I worked closely from 1978 to set up PRECODEPA. He had one of the sharpest (and wittiest) minds I’ve come across. John passed away in 2005.
  • Ken Brown

    Ken was a fantastic person to work with—he knew just how to manage people, was very supportive, and the last thing he ever tried to do was micromanage other people’s work. I learnt a great deal about program and people management from him.

Around the world in 40 years . . . Part 26: A sojourn in Sri Lanka

I visited Sri Lanka just the once. However, I don’t even remember which year or month. Only that it was the early 1990s, probably around 1993 or 1994. That was when I was planning a major rice conservation project at IRRI, and I wanted to determine if or how any Sri Lankan organizations would participate. As it turned out, for reasons that I’ll explain in due course, Sri Lanka did not join the project.

The Sri Lankan genebank, The Plant Genetic Resources Centre (PGRC) is based in Kandy in the island nation’s Central Province, of which it is the capital. It lies amongst the hills of the central plateau. The hills surrounding Kandy are covered in tea plantations. And, in many ways, Kandy is a magical place to visit. The scenery is outstanding.

Although I don’t remember in which hotel I stayed, I do remember it was perched on the summit of one of the hills, with views in every direction, as you can see in the gallery above. In the stillness of the dawn, I woke each morning to the sounds of birds calling to each other across the valleys. What a wonderful start to the day.

Kandy is home to a magnificent botanical garden (the Royal Botanical Gardens at Peradeniya just west of the city) and one of Buddhism’s most sacred places of worship, the Temple of the Tooth or Sri Dalada Maligawa, is located in the city center.


The Plant Genetic Resources Centre was opened in 1990. Its construction was a donation from the Government of Japan in 1989. So when I visited it had been open for just a few years—and looked like it. But, unlike one or two other genebanks whose construction Japan had supported in other Asian countries, the staff at PGRC were certainly making the most of their expanded facilities to store seeds and tissue culture or in vitro conservation.

Once again I am unable to name most of the people I met at PGRC, with one exception: Mr CN Sandanayake, who was one of my MSc students at the University of Birmingham in 1986.

CN Sandanayake talks with one of his colleagues at PGRC.

And as you can see from one of the photos in the gallery above, everything stops for tea!

When I discussed participation in the IRRI-led rice biodiversity project, it was clear that Sri Lanka had already made significant progress to collect and conserve indigenous rice varieties and wild species. My former colleague at IRRI, Dr Duncan Vaughan had visited Sri Lanka in the 1980s to help with the collection of wild rices.

Furthermore, PGRC had a cadre of excellent technical staff, and as you can see from the photos, excellent facilities for germplasm conservation. And, given the ongoing civil war there were many no-go areas in the country, especially in the north and east. However, in Kandy, there was no tangible signs of the conflict.

I made a side trip, with Sandanayake, to the Rice Research & Development Institute at Batalagoda, some 50km north of Kandy. Here are a couple of photos I took on that journey.

There I met with MS Dhanapala, a rice breeder who had also come to Birmingham in the 1980s to attend short courses on plant genetic resources, and also spend some time in the Department of Genetics.

Sitting, L-R: Dhanapala, me, Sandanayake. I don’t remember the names of those standing.

Sri Lanka has had a very successful rice breeding program, and many of its varieties have been adopted throughout Asia, after being shared and trialled through INGER, the IRRI-led International Network for the Genetic Evaluation of Rice, that I wrote about in 2015.


Now to return to Kandy tourism.

The Royal Botanic Gardens at Peradeniya cover almost 150 acres. There are wide open spaces to wander around, but also exquisite orchid houses to enjoy, with a multiplicity of species and varieties to take in.

As I mentioned, the Temple of the Tooth is a sacred shrine to Buddhists, and although not overrun with pilgrims during my visit was, nevertheless, quite busy.

One of the most impressive exhibits, in a side room, is a huge, stuffed elephant that died in 1988. This was Raja, a tusker who led ceremonial processions from the Temple for over 50 years.

All too soon my stay in Kandy was over, and I headed down to Colombo on the west coast to take my flight back to Singapore, and from there to the Philippines. It’s certainly a country I would like to return to.


 

Around the world in 40 years . . . Part 25: Walking the Great Wall of China

During the nineteen years I spent in the Far East, I visited China just twice. The first time was in March 1995, and this post is all about that visit. It must have been in 2009 that I was in China again, for the annual meeting of the CGIAR (Consultative Group on International Agricultural Research) held in Beijing, just across the street from the famous Beijing National Stadium (aka Bird’s Nest) built for the 2008 Olympic Games.

However, back to 1995.

Dr Bao-Rong Lu

A year earlier I had recruited Dr Bao-Rong Lu (a Chinese national from the southwest Sichuan Province) to work in IRRI’s Genetic Resources Center (GRC) on the diversity of wild rice species. Bao-Rong had just completed his PhD in Sweden at the Swedish University of Agriculture under the supervision Professor Roland von Bothmer, studying the cytogenetics of wheat species, if memory serves me correctly. He had also spent some months working at the Institute of Botany, The Chinese Academy of Sciences (IB-CAS), in Beijing prior to joining IRRI.

With a major rice biodiversity project getting underway at IRRI in 1995, I decided that a visit to China with Bao-Rong was the appropriate moment to initiate some further contacts and possible collaboration. Our visit took in three cities: Beijing, Hangzhou (in Zhejiang Province west of Shanghai), and Guangzhou (Canton) in the south.

First stop was the IB-CAS where I met with the Director (whose name I cannot recall, unfortunately) and many of the staff.

With the Director of the Institute of Botany and staff. Bao-Rong is standing on my left, and the Director on my right.

I was invited to present a seminar about the International Rice Genebank at IRRI and its role in the global conservation of rice genetic resources.

There was also some time for sightseeing around Beijing, and this was my opportunity to tick off another item on my bucket list: walking on the Great Wall of China (at Mutianyu, about 45 miles north of Beijing).

As you can see from these photos, there were few visitors, unlike scenes I have seen in the media in recent years.

We also took a tour of the Forbidden City in Beijing, and a walk around Tiananmen Square. Again not crowded! In one of the photos you can see the Great Hall of the People behind Bao-Rong. During the CGIAR meeting in Beijing that I mentioned earlier, the official dinner (and entertainment) was hosted by the Chinese in the Great Hall. It’s massive!

The photos appear hazy, because it was. It was quite cold in Beijing in March, with a stiff northwesterly breeze blowing over the city, laden with dust from the far west of China. It felt like being sand-blasted.

We also visited some Ming era tombs near Beijing, but I’m unable to find any photos of that particular visit.

On one night the Vice President of the Chinese Academy of Sciences hosted a small dinner in my honor. On another, Bao-Rong introduced me to the delights of spicy Sichuan cuisine. There was a Sichuan restaurant in our hotel where all the staff were from the province.

Trevor Williams

Later that same evening, as Bao-Rong and I were enjoying a beer in the bar overlooking the hotel reception, I saw someone who I recognised enter the dining room. I had to investigate. And, lo and behold, it was Trevor Williams who had supervised my MSc dissertation at the University of Birmingham in 1971. Around 1977, Trevor left Birmingham to become the first Director of the International Board for Plant Genetic Resources (IBPGR – now Bioversity International) in Rome. In 1995 I hadn’t seen Trevor for about six years, and so we spent the rest of the evening catching up over rather too many beers. Having left IBPGR by then, he was in Beijing setting up an organization that would become INBAR, the International Network for Bamboo and Rattan with its headquarters in Beijing.

After a few days in Beijing, we headed south to the city of Hangzhou (inland from Shanghai on the Qiantang River) in Zhejiang province. We were there to visit the China National Rice Research Institute (CNRRI) and meet with its director Professor Ying Cunshan. Professor Ying participated in the rice biodiversity project as a member of the project Steering Committee. CNRRI is the home of China’s largest rice genebank, which was modelled (inadvisedly in my opinion) on the genebank at IRRI.

After a couple of days in Hangzhou, we headed southwest to the city of Guangzhou (Canton) and I experienced one of the most nerve-wracking flights ever.

Much as I am fascinated by aviation in general, I’m somewhat of a nervous flyer. And in the mid-1990s Chinese airlines were only just beginning to modernise their fleets with Boeing and Airbus aircraft. Many were still flying Soviet-era Russian aircraft, like the Tupolev (probably a ‘154’) that was assigned to our flight. On that morning, flights out of Hangzhou were delayed due to fog, and at the same time Guangzhou was also fogged in. Over a period of a couple hours, other flights (of mainly new aircraft) did depart, leaving just the Tupolev on the apron for our flight. Eventually the flight was called and we made our way out to the aircraft. Looking around the cabin as I made my way to my seat, it crossed my mind that this aircraft had seen better days.

Anyway, we took off and headed for Guangzhou. Approaching that city after a flight of about 90 minutes, the captain informed us that fog was still hanging over the airport but he would continue the landing. Only to abort that just before touching down, and returning to Hangzhou! My nerves were on edge. After refuelling, and a further delay, we departed again. This time we did find a gap in the fog and landed. As we were on our final approach and seconds from touch-down, a female passenger immediately in front of me decided to get out of her seat to retrieve her hand luggage from the overhead bin. That was the final straw for me, and I shouted at her, in no uncertain terms, to sit the f*** down. Not my best moment, I admit.

In Guangzhou, our destination was the Guangzhou wild rice nursery and meet with the staff (again I don’t remember who precisely). I believe the nursery was managed through the Guangzhou Academy of Agricultural Sciences. As in Beijing, I gave another seminar here.

In a 2005 paper, Bao-Rong and others has written about wild rice conservation in China.


Completing our visit to Guangzhou, I took a flight into Hong Kong (maybe under 40 minutes) to connect with another back to Manila.

Although China did not participate directly in the rice biodiversity project since the country had already invested heavily in rice collection and conservation, Professor Ying Cunshan served on the Steering Committee for the 5-year life of the project. We felt that his experience, and recognition among other rice scientists, would be an invaluable addition to the team.

I have two particular reflections on this first trip to China. First, in crowded areas the Chinese had little ‘respect’ for personal space, and I often found myself checking my pace of walking as others crossed in front of me, seemingly oblivious of the fact that I was there. And it wasn’t just me, being a foreigner. It just seemed the normal thing to do.

Secondly, I realised that I am not a very adventurous eater. Some of the dishes I was presented with did not encourage my appetite. There was certainly a lack of synchronization between my stomach, eyes and brain. I did find Sichuanese cooking delicious, however. In Guangzhou, where many ‘exotic’ dishes were prepared, I got round any difficulties by explaining to my hosts, through Bao-Rong, that I was vegetarian. And those dishes were equally delicious.

Bao-Rong remained at IRRI for two contracts, a total of six years. After he left IRRI in 2000, he returned to China and it wasn’t long before he joined Fudan University in Shanghai. He is now Professor and Chairman of the Department of Ecology and Evolutionary Biology, and Deputy Director of the Institute of Biodiversity Science. He currently serves as a Member of the Chinese National Biosafety Committee.


 

Look out, he’s behind you! . . . Oh no, he’s not!

The pantomime season ended a week or so ago here in the UK. Pantomime?

Pantomime is a marvellous and wonderful (if a little eccentric!) British institution.

Pantomimes take place around the Christmas period and are nearly always based on well known children’s stories such as Peter Pan, Aladdin, Cinderella, Sleeping Beauty etc. Pantomimes are performed not only in the best theatres in the land but also in village halls throughout Britain. Whether a lavish professional performance or a hammy local amateur dramatic production, all pantomimes are well attended.

Ellen Castelow wrote this for the Historic UK website. And if you want to know a little more about pantomimes, just take a quick look at this YouTube video.

In the mid-1990s at IRRI (the International Rice Research Institute in the Philippines where I worked from 1991-2010), a group of us staged our own pantomimes in the IRRI Auditorium in the period leading up to Christmas, although not conforming entirely to the format described in the video.

With Kate Kirk (wife of soil chemist Guy) as Director, there were three pantomimes from 1994 to 1996. I took part in two of these: Snow White (or was it Sleeping Beauty?) and Robin Hood and his Merry Men, but had to drop out of the third, Aladdin, during rehearsals due to unforeseen travel commitments.

These good memories have resurfaced because I referred to the Robin Hood pantomime in my recent tribute to my friend Martin Mortimer who passed away just before Christmas last year. And also because in the process of working my way through boxes of old photographs in preparation for our house move later this year, I came across a small album of photos from Robin Hood and his Merry Men that was the pre-Christmas highlight at IRRI in mid-December 1995.

I joined IRRI in July 1991 as Head of the Genetic Resources Center, and when Kate asked me to be part of one of her productions, I jumped at the chance. Since my undergraduate days at Southampton I’d enjoyed taking part in reviews and the like, but only on an occasional basis.

It was Christmas 1992 that we staged our first panto, Snow White/Sleeping Beauty, in which I played a dipsomaniac King, father of the leading lady.

We had great fun with Robin Hood, inspired by Mel Brooks’ 1993 film Robin Hood: Men in Tights.

I guess there must have been five performances, Wednesday to Saturday (with an afternoon matinee on the Saturday).

So who was involved? As I mentioned, Kate Kirk was the Director, and Crissan Zeigler (wife of IRRI Program Leader and plant pathologist, Bob Zeigler) was the Producer.

L-R: Crissan Zeigler, Rebecca Nelson (as Maid Marian), and Kate Kirk, with Nick Zeigler (as Will Scarlet photobombing in the background).

Most of us had little stage experience, so we were fortunate to depend upon Jay Herrera (a semi-professional actor from Manila) and Pam Denning (wife of Glenn Denning, then head of IRRI’s International Programs Management Office and now Professor of Professional Practice in International and Public Affairs at Columbia University) as the ‘anchors’ around whom we attempted to appear better than we were.

Where are they now?
Robin Hood was played by Michael Price, husband of visiting scientist and anthropologist Lisa M Price (now Professor of Anthropology at Oregon State University).

Rebecca Nelson, a plant pathologist) played Maid Marian. After leaving IRRI (around 1996 or so) she moved to the International Potato Center (CIP) in Lima, Peru to head research on late blight disease. She is now Professor at Cornell University.

Rice agronomist Len Wade was Little John. After leaving IRRI in 2002, Len held Chairs in Agronomy at the University of Western Australia and Charles Sturt University in his native Australia. Following retirement he is now Honorary Professor at the University of Queensland.

Friar Tuck was played by Rainfed Lowland Rice Program Leader and plant pathologist Bob Zeigler, who left IRRI in 1998 to become Chair of the Department of Plant Pathology at Kansas State University. He returned to IRRI in 2005 as Director General.

Guy Kirk was a soil chemist at IRRI for thirteen years. After leaving the institute, he returned to the UK, took a sabbatical at the University of Cambridge to write a book on The Biogeochemistry of Submerged Soils, and in 2003 was appointed Professor of Soil Systems at Cranfield University.

John Bennett was Senior Molecular Biologist at IRRI, and retired about fifteen years ago.

Jane Guy from South Africa (but domiciled in Canada) played the nanny or Yaya (in Filipino) whose husband Peter was an Environment Project Manager for a Canadian-funded project in Los Baños during 1994 and 1995. Their daughter Katherine was one of the Forest Fairies (kneeling in the middle in the photo above) who, in 2018, married Chris, the elder son of my close colleague and head of IRRI Communication and Publications Services, Gene Hettel.

As for myself, I played a very camp Prince John, dyeing my whiskers yellow to match the luxuriant wig I had acquired. In May 2001, I moved into a senior management position at IRRI, as Director for Program Planning and Communications (DPPC) until my retirement in April 2010.

Happy days!

Genebanks are the future . . . but there is a big challenge ahead

Our ability to adapt to changing climates will be determined, to a considerable extent, upon our ability to feed ourselves, to provide shelter and clothing, and for many peoples in many developing countries there will be problems in obtaining fuelwood for cooking or heating.

My close friend and former colleague Professor Brian Ford-Lloyd and I wrote that 30 years ago in the first chapter [1] of the book on climate change and genetic resources that we edited with Martin Parry.

We also wrote that to avert famine it would be necessary to raise crop yields and identify and use the sorts of genetic resources to contribute to this effort. Fortunately, these genetic resources are, to a large extent, already conserved in genebanks around the world.

In a recent post, I argued that, in the face of climate change, genebanks are the future. And while I hold to that assertion, I must also highlight a challenge that must be addressed—with greater urgency—and one that I already raised 30 years ago!

And that challenge is all about the potential impacts of climate change on genebank operations. I’m concerned about how rising temperatures and changing seasons might affect the ability of a genebank to produce good quality seeds during initial multiplication or thereafter to regenerate seed stocks.

We also have limited information how the environmental pest and plant pathogen load will change under a changing climate. That’s a particular concern for plant species that cannot be stored as seeds but are conserved in field genebanks. In this, the International Year of Plant Health, it is a particular genebank issue worthy of more attention.

Furthermore, we shouldn’t discount possible increases in genebank costs as cooling equipment works harder to maintain cold rooms at the desired temperatures of -18°C for long-term conservation (in so-called Base Collections), or just above 0°C for germplasm that is available for distribution and exchange (in Active Collections), the situation found in many genebanks.


Many (but not all) genebanks were set up in parts of the world where the crops they conserve are important, and where many originated, in so-called ‘centers of diversity’. That holds particularly for the international genebanks managed in eleven of the CGIAR centers, such as for potatoes at the International Potato Center (CIP) in Peru, beans and cassava at the International Center for Tropical Agriculture (CIAT) in Colombia, or rice at the International Rice Research Institute (IRRI) in the Philippines, to give just three examples.

But there are exceptions. CIMMYT, the International Maize and Wheat Improvement Center (located just outside Mexico City) certainly lies in the center of diversity for maize, but not wheat, which is a crop that was domesticated and evolved under domestication in the Near East and fringes of the Mediterranean. Another exception is Bioversity International, based in Rome that maintains an important collection of bananas (Musa spp.) as tissue culture samples (known as in vitro conservation) as well as samples stored frozen (or cryopreserved) at the temperature of liquid nitrogen (-196°C) in Belgium at the Katholieke Universiteit Leuven (KU Leuven).

You can find out more about the CGIAR genebanks on the Genebank Platform website.

As the network of genebanks expanded worldwide, with almost every country setting up at least one national genebank, many genebanks now hold samples of varieties and wild species from distance regions. And it does have some important implications for long-term conservation and regeneration, and exchange of germplasm.


Long-term conservation of many plant species in genebanks is possible because their seeds can be dried to a low moisture content and stored at low temperature. We refer to these seeds as orthodox, and we have a pretty good idea of how to dry them to an optimum moisture content (although research at IRRI has thrown new light on some of the critical drying processes). Provided they can be kept dry and cool, we can predict—with some confidence—how long they will survive in storage before they need to be grown again, or ‘regenerated’, to produce healthy seeds stocks.

On the other hand, the seeds of some species, many from the tropics, do not tolerate desiccation or low temperature storage. We refer to the seeds of these species as recalcitrant. There again, there is also a group of crops that cannot be stored as seeds but must be maintained, like the banana example referred to above, as tissue cultures or cryopreserved, if technically feasible; or in field genebanks because they reproduce vegetatively. The potato for example is grown from tubers, and for any variety, each tuber is genetically identical (a clone) to all the others of that variety. Although potatoes do produce seeds (often in abundance), they do not breed true. That’s why conservation of the original varieties is so important.

However, seeds do not live forever, and periodically regenerated if there are signs of declining viability. Or when seed stocks have become depleted because they have been sent to breeders and researchers around the world.


Climate change is already affecting crop productivity in some parts of the world. Increases in temperature (notably higher nighttime temperatures) are linked with a reduction of fertility in rice [2] for example. Stressed plants produce seeds of lower quality and, in wheat, have an effect on seedling vigour and potentially on yield [3].

Many (perhaps most) genebanks aim to grow their germplasm close to the genebank location, although this may not always be possible. Will the environments of genebank locations remain constant under climate change? Most certainly not. Temperatures have already risen, and are predicted to increase even further unless governments really do take concerted action to reduce our carbon footprint. While temperatures will increase, daylength will remain constant. Under climate change we will see new combinations of temperature and daylength. Response to daylength (or photoperiodism) is a key adaptive trait in many plant species. It is already a challenge to grow some genebank samples at a single location because of their wide latitudinal provenance.

Richard Ellis

Incidentally, 30 years on, it’s worthwhile to take a second look at Chapter 6 in our genetic resources and climate change book [4] by Professor Richard Ellis and colleagues at the University of Reading on the relationship between temperature and crop development and growth.

Seed quality is all important for genebank managers. Unlike farmers, however, they are less concerned about yield per se. They do need to understand the impacts of higher temperatures, drought, or submergence—and when they occur in a plant’s life cycle—on seed quality, because seed quality is a key determinant of long-term survival of seeds.

In a recent article, Richard wrote this: . . . when scientists breed new crop varieties using genebank samples as “parents”, they should include the ability to produce high-quality seed in stressful environments in the variety’s selected traits. In this way, we should be able to produce new varieties of seeds that can withstand the increasingly extreme pressures of climate change.

While a genebank might be able to regenerate its conserved germplasm closeby today, to what extent will these ‘regeneration environments’ become ‘stressful environments’ under a changing climate? What measures must a genebank take to ensure the production of the highest quality seeds? Furthermore, how will the pest and disease load change, and what impact will that have during regeneration and, perhaps more importantly, on germplasm conserved in field genebanks?

We were faced by a similar situation almost 30 years ago after I had joined IRRI. There’s no question that IRRI conserves, in its International Rice Genebank, the world’s largest and genetically most diverse collection of rice varieties and wild species.

Kameswara Rao

One important group of rice varieties, the so-called japonica rices originated in temperate zones, and it was tricky to produce high quality seeds in Los Baños (14°N). With my colleague Kameswara Rao (who received his PhD in Richard’s lab at Reading), we carefully analysed the factors affecting seed quality in the japonica varieties grown in Los Baños [5], and adapted the regeneration cycle to the most appropriate time of year. Given that water was not a limiting factor (there were irrigation ponds on the IRRI Experiment Station) we were not constrained by the changing seasons as such. This would not be possible for all genebanks where growing seasons are more differentiated, in terms of temperature and water availability.


I did look into the possibility of growing the japonica (and other ‘difficult’ varieties) at other sites, even outside the Philippines. What seemed, at the outset, as a logical solution to a challenging problem, became a logistical nightmare.

I was concerned that the International Rice Genebank could ‘lose’ control of the management of germplasm samples in the field unless genebank staff were assigned to oversee that work, even in another country. Afterall, the reputation of the genebank lies in its ability to safely conserve germplasm over the long-term and safely distribute seeds, conditions I was not prepared to compromise.

There were also various plant quarantine issues, seemingly insurmountable. Plant quarantine personnel are, by outlook, a conservative bunch of people. And with good reason. IRRI successfully operates its germplasm exchange (both receipt and distribution) under the auspices of the Philippines Department of Agriculture’s National Plant Quarantine Services Division (of the Bureau of Plant Industry). The institute’s Seed Health Unit carries out all the tests necessary to certify all imports and exports of rice seeds meet exacting quarantine standards. All samples received by IRRI must be tested and, if they are destined for future distribution, must be grown in the field at IRRI for further observation and certification. That would negate the advantages of producing seeds in a ‘better’ environment. Countries like the USA or Russia that cover a huge range of latitude and longitude have a network of experiment stations where germplasm could be grown, and under the same plant quarantine jurisdiction. For many countries and their genebanks, that will just not be an option.

So the challenge for genebank managers is to make sure the impact of climate change on germplasm management and exchange is part of risk management. And begin discussions (if they have not already started) to determine how inter-genebank collaboration could overcome some of the potential constraints I have raised.

Never have genebanks been so relevant . . . or needed

There has perhaps never been a better justification for conservation of seeds in genebanks, or ex situ conservation as it’s commonly known.

The devastating bush fires that have ravaged huge swathes of eastern Australia have highlighted the fragility of environments that are being affected adversely by the consequences of climate change. It’s a wake-up call, even though some of us were commenting on this a generation ago (and more recently in 2014).

While many news stories have emotionally focused on the impact of the fires on wildlife—the injury to and death of millions of animals—very little has appeared in the media about the impacts on plant species. One story stood out, however: the extraordinary measures that firefighters took to protect the only natural stand of ancient Wollemi pines at a secret location in the Blue Mountains west of Sydney.

In another story I came across, there are concerns that a wild species of sorghum native to East Gippsland in southeast Australia may now be headed towards extinction as fires swept across its habitats. Only time will tell whether this particular species has survived.

Bush fires are not uncommon in Australia and many other parts of the world. Vegetation is, however, quite resilient and, given time, often recovers to a semblance of what was there before fires ravaged the landscape, although the balance of species may be disrupted for a few years.

Clearly nature is under threat. Indeed, in an article in The Guardian on 20 January 2020 the acting executive secretary of the UN Convention on Biological Diversity, Elizabeth Maruma Mrema, is quoted as imploring ‘governments to ensure 2020 is not just another “year of conferences” on the ongoing ecological destruction of the planet, urging countries to take definitive action on deforestation, pollution and the climate crisis.’

Catastrophic fires, and other effects of environmental degradation and climate change, vividly illustrate the necessity of having a dual conservation strategy, backing up conservation in nature, or in situ conservation, with conservation of seeds in genebanks, where appropriate. It’s clear that relying in situ conservation alone is too high a risk to take.

About 25 years ago, while I was leading the genetic conservation program at the International Rice Research Institute (IRRI) in the Philippines, and conserving the world’s largest and most diverse collection of rice varieties and wild species in the International Rice Genebank, vocal lobby groups were pressing hard in several international forums and the media to redirect conservation away from genebanks (they were often referred to as ‘gene morgues’) towards in situ conservation, in nature for wild species or on-farm for cultivated varieties.

The criticism of many genebanks, including some of those managed at centers of the Consultative Group for International Agricultural Research or CGIAR, was not unwarranted. Insufficient attention was given to applying internationally-agreed genebank standards. This was not entirely the fault of genebank managers, both inside and outside the CGIAR. They were often starved of funds, living hand to mouth, year to year as it were, and expected to manage a long-term conservation commitment on inadequate annual budgets.

Standards in the eleven CGIAR genebanks have been raised through the Genebank Platform, supported by the Crop Trust. Between them, not only do the CGIAR genebanks conserve some of the most world’s important collections of genetic resources of cereals, legumes, and roots and tubers, but these collections have been studied in depth to find useful traits, and the volume of germplasm shared annually for research and production is impressive. Just take a look at the data for the years 2012-2018.

Other international efforts like the Crop Wild Relatives Project (supported by the Government of Norway), and managed by the Crop Trust with the Royal Botanic Gardens, Kew have focused attention on the importance of conserving the wild relatives of crop plants as they are often genetically endowed with traits not found in their domesticated derivatives. My own experience studying nematode resistance in wild potatoes from Bolivia for example illustrated the importance of wild species for crop improvement.

Today, we have a whole new suite of tools to study the crop varieties and wild species conserved in genebanks around the world. As the genome of each new species is sequenced, another door is opened on the genetic diversity of nature, how it’s organized, and how genes control different traits. Indeed an argument has recently been made to genotype all samples (or accessions in the ‘official’ parlance) in a genebank. Certainly this is an approach that was merely a dream only two decades ago.

I still argue, however, that in tandem with the molecular analysis of crop diversity, there must be an in-depth evaluation of how different varieties behave in real environments. In joint research between former colleagues of mine at The University of Birmingham (Professors Brian Ford-Lloyd and John Newbury and Dr Parminder Virk) and myself at IRRI in the 1990s, we demonstrated the predictive value of molecular markers for several quantitative characters associated with crop productivity. Somewhat derided at the time, association genetics has become an important approach to study crop diversity.

I’ve been publishing about climate change and the value of plant genetic resources for over 30 years, beginning when there was far more skepticism about this phenomenon than today. At a conference on Crop Networks, held in Wageningen in the Netherlands in December 1990, I presented a paper outlining the need for collaborative research to study germplasm collections in the face of climate change.

And in that paper I argued that widespread testing in replicated field trials would be necessary to identify useful germplasm. With the addition nowadays of molecular markers and genome-wide detailed information for many species, there is now a much better opportunity to evaluate germplasm to identify gene sources that can help protect crops against the worst ravages of climate change and maintain agricultural productivity. Even though political leaders like Donald Trump and Scott Morrison continue to deny climate change (or merely pay lip service), society as a whole cannot ignore the issue. Afterall, for a predicted global population of 9.8 billion by 2050, most of whom will not produce their own food, continued agricultural productivity is an absolute necessity. The conservation, evaluation, and use of plant genetic resources stored in the world’s genebanks is a key component of achieving that goal.

Genebanks are the future! However, in a follow-up story, I write that genebanks still face a major challenge under a changing climate. Read more here.

New Year, new job . . .

Job-wise, January has been an important month during my career, on several occasions.

Forty-seven years ago, I was getting ready to fly to Peru, to join the International Potato Center (CIP) in Lima. I actually flew out from London on 4 January 1973.

In January 1981, I was invited to interview for a Lectureship at the University of Birmingham, and flew back from Peru towards the end of the month. Offered the position there and then, I took up my post on 1 April.

A decade later—and increasingly disillusioned with the UK’s higher education sector—I had applied for the position of Head of the Genetic Resources Center (GRC) at the International Rice Research Institute in Los Baños, Philippines, and at the end of the first week of January, flew to the Philippines for an interview. I was offered the position towards the end of the month, and I joined IRRI on 1 July.

Ron Cantrell

In mid-January 2001, IRRI’s Director General, Dr. Ron Cantrell, asked me to stop by his office. Planning to revamp IRRI’s donor relations and fund-raising as well as management of research projects, he invited me to lead a new initiative with appointment at Director level and membership of the institute’s senior management team. It took me a few weeks to decide. I had to give up my life’s work until then, working with crop diversity and gene banking. However, on 1 May, I became IRRI’s Director for Program Planning and Coordination (DPPC, later Communications).

Then, on 1 January 2010 (and just four months before I retired), I relinquished that role (but not my Directorship) to my close colleague, Ms. Corinta Guerta.

Let me tell you about Corinta. She is one of the most remarkable persons it has been my privilege to work with.

When I set up the Office for Program Planning and Coordination in 2001, I inherited several staff from an existing project management office. Very quickly I realised I would be unable to make any significant changes with those staff in place. They had little imagination of what might be achieved if we organized ourselves differently.

One thing I did know, however: I wanted my secretary from GRC, Zeny Federico, to join me in DPPC, and she readily accepted my invitation.

When discussing the move to DPPC with Ron Cantrell (and the two Deputy Directors General, Ren Wang and Willy Padolina), I explained the need for a highly qualified and motivated person to be my 2IC, and I suggested that Corinta would be an ideal candidate. In fact, I remember explicitly stating that I could make a success of DPPC with ‘someone like Corinta’ assisting me. That raised some eyebrows.

Why? Well, for one thing I had never worked with Corinta. As a member of the national support staff she worked in a different research division altogether. As a soil chemist! Then she had no (or very limited) administrative/management experience. As a BS chemistry graduate (one of the topnotchers, as they say in the Philippines, in the nationwide professional licence exam for chemists in her year), she joined IRRI as a Research Assistant in July 1975.

During my early years at IRRI, our paths crossed only occasionally. But she caught my eye. I had seen her in action, so to speak, during a couple of institute-wide initiatives/meetings contributing very effectively to the discussions.

Then, around 1998 or 1999, the institute created the new position of Senior Associate Scientist and invited qualified members of the national (Filipino) staff to apply, supported by references.

There were strict criteria. Candidates had to have a Masters degree and a minimum number of years service. Corinta had an MS degree in soil science from the University of the Philippines-Los Baños (UPLB). Candidates had to present a seminar, open to all staff to attend, and then they were interviewed for about an hour by the promotions committee, of which I was a member.

We received eighteen applications, if memory serves me correctly. As the only member of the committee who attended all the seminars and interviews, I was uniquely placed to objectively compare all candidates. Some of my committee colleagues were unable to reschedule their travel or other commitments so missed some seminars or interviews.

After we had met with all candidates, it was abundantly clear to everyone on the committee who was the top candidate: Corinta. Not only No. 1 on the list, but significantly ahead of all the others. Indeed, I argued (with some passion) that really only one candidate was worthy of promotion. Obviously that was not going to happen and after some further consideration, about eleven staff were promoted.

But Corinta had clearly made an impression on me. I forget if we asked all candidates to address the same topic for their seminar or they could choose one in their own field of expertise. But they were asked to address strategic issues facing the institute. Corinta was the only one (in my opinion) who had such a vision and could express that vision coherently as well explain how IRRI’s research would benefit rice farmers. We explored some of these ideas in her interview, and she stood her ground under some pretty intense questioning.

Once I moved to DPPC, I asked Corinta to come and see me. She had no idea what I was about to surprise her with. Indeed, I think she was quite taken aback and, initially, rather reluctant to even consider a move out of research. But my persistence was greater than hers, and on 1 August she joined DPPC and found herself in the deep end of project management. And the first couple of years were doubly difficult (and tragic) as she supported her husband in his fight against cancer.

It’s no exaggeration to say that I could not have made a success of DPPC (streamlining IRRI’s project management systems, budgeting, donor relations, and the like) without Corinta’s wholesale support and growing expertise. She played a critical role in identifying the staff who joined DPPC: Monina, Sol, Yeyet, Vel, and Eric (our database administrator and developer). One of the original staff, another Sol, stayed on for a few months as an office assistant but was replaced by Vel. When Monina left in 2002, Sol No. 2 joined us. She departed IRRI in 2008 and was replaced by Yeyet.

Christmas 2001 at Ugu Bigyan Pottery in Tiaong, Quezon Province. L-R: Monina, Corinta, Zeny, Sol, and Eric.

Christmas 2004 at Antonio’s, Tagaytay. L-R: me, Sol O., Eric, Corinta, Vel, and Zeny.

March 2009 during the DPPC trip to Mountain Province with L-R, and enjoying a welcome beer: Corinta, Zeny, driver, Vel, Yeyet, Eric, and me.

So, in January 2010, Corinta tooks the reins of DPPC, and grew even more in her role. Over the years she had established great rapport with the internationally-recruited research staff, and quickly gained their respect. They would often consult her for advice before bothering me.

Bob Zeigler

I felt immensely proud when, after my retirement from IRRI at the end of April 2010, the Director General, Bob Zeigler in his wisdom made Corinta the institute’s Director for External Relations. And she remained in that role until her retirement a couple of years ago. Since then, she has been a consultant to the new Director of SEARCA (the Southeast Asian Regional Center for Graduate Study and Research in Agriculture, a non-profit organization based in Los Baños) and former IRRI plant breeder Glenn Gregorio, helping to frame a new strategic plan.

For someone who had joined IRRI more than 40 years earlier, the progression from Research Assistant to Director has been remarkable, unprecedented even. But thoroughly deserved.

In February 2012, when I was invested as an Officer of the Most Excellent Order of the British Empire (OBE) in a ceremony at Buckingham Palace in London, I had the honour of Corinta joining my wife Steph and younger daughter Philippa as one of my three guests.

That for me was also a recognition of the part Corinta contributed to my success and nomination. Thank you!

Yes, we’ll meet on the other side . . .

Last night I heard the sad news—not totally unexpected—that my good friend and former colleague at the International Rice Research Institute (IRRI), Professor Martin Mortimer had passed away, aged 71 [1], on 22 December after a short illness. Diagnosed with a brain tumour only in November, he knew he only had a short time left to him. From a note he sent round to friends and colleagues at the beginning of December, he faced his fate with equanimity but without pain, calmly reflecting on life and the joys that his family had brought him, ending his ‘ramblings’ that he would see us on the other side [2].

Yes, Martin, we will. Rest in Peace [3].

After studying at Bangor University (formerly University College of North Wales [4]), he joined the faculty of the University of Liverpool in 1975, remaining there for 44 years, although only part-time more recently.

After numerous organizational changes at the university, he became Head of the Department of Plant Science, and latterly Professor of Agricultural Ecology in the Institute of Integrative Biology. In this video, Martin describes the important role of the institute in understanding and developing sustainable food systems.

Martin was a plant population biologist, studying the application of agro-ecology in tropical and temperate agro-ecosystems, particularly as it related to weed management in rice and wheat systems.

It was as a weed biologist/ecologist that Martin joined IRRI (seconded from Liverpool) in 1996, and spent seven years at the institute, returning to his university post in 2002. But he remained connected with IRRI for many years afterwards, often spending a few weeks each year participating in weed research and helping to develop collaborations with institutes in South Asia. He published widely in his chosen field, and Dynamics of Weed Populations (with Roger Cousens of the Western Australia Department of Agriculture, and published by Cambridge University Press in 1995) was a significant contribution.

In this photo, Martin is describing aspects of his research on weed dynamics to members of IRRI’s Board of Trustees (BoT). Behind Martin’s right shoulder stands Ron Cantrell, Director General, and behind his left shoulder, Dr Rudy Rabbinge, Chair of the BoT.

Martin was particularly proud of his role in fostering collaboration between the University of Liverpool and two universities in the Philippines, to promote graduate studies leading to Masters and PhD degrees. In 2018 he welcomed a delegation from the Philippines to Liverpool.

My first contact with Martin actually came during his visit to IRRI at the end of 1995 when he was interviewed for the weed scientist position. Over three Christmases, a small group of us staged ‘traditional’ English pantomimes. In the 1995 production, based (very) loosely on the story of Robin Hood and His Merrie Men, I played a camp Prince John, presiding, in one act, over an archery contest. We had already decided to ‘invite’ a member of the audience on stage either to fire an arrow, or be the target. I don’t remember which. Knowing Martin was in the audience, we chose him and he entered into the spirit of the evening.

Martin and I became firm friends, and he would often dine with Steph and me. It was a particular delight if our other good friend John Sheehy joined us as well, or we dined at John’s and Martin was there also.

A splendid evening Chez Sheehy, with (L-R): Steph, Graham McLaren, Martin, Sue McLaren, and John.

Martin and John sharing a tall tale.

Martin learned to scuba dive while in the Philippines, and he and I were often dive buddies on the weekends we were at Arthur’s Place together. On another memorable occasion, Martin and his wife Sue joined a group of friends to scale Mt. Makiling, the 3500 ft dormant (extinct?) volcano that dominates the skyline over IRRI and Los Baños, on May Day 2000.

L: Sue and Martin Mortimer, and Graham McLaren. R: me, Steph, Sue, Graham and Sue McLaren.

I haven’t seen Martin for a number of years, although we kept in touch by email. I always referred to him as ‘Lord Fazakerley’ (because of his Liverpool connections, Fazakerley being a district in Liverpool), and him referring to me as ‘Lord Brum’ (because of my University of Birmingham connections). Only earlier this year we had been corresponding frequently as we drafted obituaries for our dear friend John Sheehy for publication in national newspapers. Little did we suspect that Martin’s life would be cruelly shortened so soon afterwards.

I thought I had already finished blogging for 2019. But I couldn’t let Martin’s sad passing go unrecognised. My thoughts are with his family: wife Sue and son Hugh, and step-daughter and -son, Andrea and Fergus and their families.


30 December
After I had published this tribute to Martin yesterday, my friend and former IRRI colleague Gene Hettel (who was Head of the Communication and Publications Services) posted this short video on YouTube which brilliantly shows Martin’s sense of humour. In the video, Gene’s wife Aurora (who is from the Philippines) comments on Martin’s English accent. Enjoy!

8 January 2020
My friend and former colleague Gene Hettel posted this tribute to Martin on the IRRI website.


[1] Born on 7 January 1948, son of Dorothy Margaret and John Knowles Mortimer of Maidstone, Kent. Martin never knew his father, who died (of cancer) three months before Martin was born. Martin was brought up by his mother on a farm in Kent.

[2] Martin’s message to friends and colleagues was inspirational. The family have kindly given me permission to reproduce this excerpt, which illustrates Martin’s concern, as an evolutionary biologist, about the environment and humanity’s need to tackle head-on the challenge of climate change:

You will all know my attitude to climate change and the fact that I have been encouraging you all to address that major issue. As I die I see the rise of populism and selfishness as a major problem and it depresses me enormously, I genuinely think that the individual can do something about it. Lifestyles will have to change. And indeed the Mortimer lifestyle started to change (we moved house! ). My family bought into this and I would encourage yours to. 

[3] Martin’s funeral was held in Wrexham on 9 January 2020. Click on this link to view a copy of the Order of Service of Thanksgiving.

[4] BSc 1969 in Agricultural Botany; PhD 1972 in Plant Ecology (Studies of germination and establishment of selected species). After his PhD, Martin completed (1972-1975) a Lord Leverhulme post-doctoral fellowship at Bangor and the University of Wisconsin, studying the genetics of the Phytophtora group of plant pathogens.

In 1971, Martin joined the University College of Bangor Nepal Expedition under the leadership of John Witcombe, now a Professorial Research Fellow at Bangor. Photos reproduced courtesy of John Witcombe (the last four panoramic photos were taken by Martin). They made important collections of wheat and barley during this expedition, and these samples may well have been the material studied by Altaf Rao who was a student with me in genetic resources at the University of Birmingham, 1970-71.


This obituary, by his son Hugh, was published in The Guardian on 11 February 2020. A Celebration of Martin’s life was held on the Wirral (where Martin and Sue had lived for any years before moving near Llangollen a few years back) on 29 February.


 

Have [botany] degree . . . will travel (#iamabotanist)

One thing I had known from a young boy was that I wanted to see the world; and work overseas if possible. Following somewhat in the footsteps of my parents, Fred and Lilian Jackson.

Who would have thought that a degree in botany would open up so many opportunities?

Come 1 January, it will be 47 years since I joined the staff of the International Potato Center (CIP) in Lima, Peru, and the start of a 37 year career in the plant sciences: as a researcher, teacher, and manager. Where has the time flown?

After eight years in South and Central America, I spent a decade on the faculty of the School of Biological Sciences at the University of Birmingham. Then, in 1991, I headed to Southeast Asia, spending almost 19 years at the International Rice Research Institute (IRRI) in the Philippines, before retiring in 2010.

However, I have to admit that Lady Luck has often been on my side, because my academic career didn’t get off to an auspicious start and almost thwarted my ambitions.

While I enjoyed my BSc degree course at the University of Southampton (in environmental botany and geography) I was frankly not a very talented nor particularly industrious student. I just didn’t know how to study, and always came up short in exams. And, on reflection, I guess I burnt the candle more at one end than the other.

It would hard to underestimate just how disappointed I was, in June 1970, to learn I’d been awarded a Lower Second Class (2ii) degree, not the Upper Second (2i) that I aspired to. I could have kicked myself. Why had I not applied myself better?

But redemption was on the horizon.

Prof. Jack Hawkes

In February 1970, Professor Jack Hawkes (head of the Department of Botany at the University of Birmingham) interviewed me for a place on the MSc Course Conservation and Utilization of Plant Genetic Resources, that had opened its doors to the first cohort some months earlier. I must have made a favorable impression, because he offered me a place for September.

But how was I to support myself for the one year course, and pay the tuition  fees? I didn’t have any private means and, in 1970, the Course had not yet been recognized for designated studentships by any of the UK’s research councils.

Through the summer months I was on tenterhooks, and with the end of August approaching, started seriously to think about finding a job instead.

Then salvation arrived in the form of a phone call from Professor Hawkes, that the university had awarded me a modest studentship to cover living expenses and accommodation (about £5 a week, or equivalent to about £66 in today’s money) as well as paying the tuition fees. I could hardly believe the good news.

Prof. Trevor Williams

By the middle of September I joined four other students (from Venezuela, Pakistan, Turkey, and Nigeria) to learn all about the importance of crop plant diversity. Over the next year, discovered my academic mojo. I completed my MSc dissertation on lentils under Course Tutor (and future Director General of the International Board for Plant Genetic Resources, now Bioversity International), Professor Trevor Williams.

Starting a career in international agricultural research
Just before Christmas 1970, Hawkes traveled to Peru and Bolivia to collect wild potatoes. On his return in February 1971, he dangled the possibility of a one year position in Peru (somewhere I had always wanted to visit) to manage the potato germplasm collection at CIP while a Peruvian researcher came to Birmingham for training on the MSc Course. Then, in mid-summer, CIP’s Director General, Dr. Richard Sawyer, visited Birmingham and confirmed the position at CIP beginning in September 1971.

But things didn’t exactly go to plan. Funding from the British government’s overseas development aid budget to support my position at CIP didn’t materialise until January 1973. So, during the intervening 15 months, I began a PhD research project on potatoes (under the supervision of Professor Hawkes), continuing with that particular project as part of my overall duties once I’d joined CIP in Lima, under the co-supervision of Dr. Roger Rowe. That work took me all over the Andes—by road, on horseback, and on foot—collecting native varieties of potatoes for the CIP genebank.

Screening potatoes in Turrialba, Costa Rica for resistance to bacterial wilt.

After successfully completing my PhD in December 1975, I transferred to CIP’s Outreach Program in Central America, moved to Costa Rica for the next 4½ years, and began research on potato diseases, adaptation of potatoes to warm climates, and seed production. This was quite a change from my thesis research, but I acquired valuable experience about many different aspects of potato production. I learnt to grow a crop of potatoes!

But this posting was not just about research. After a year, my regional leader (based in Mexico) moved to the USA to pursue his PhD, and CIP asked me to take over as regional research leader. Thus I began to develop an interest in and (if I might be permitted to say) a flair for research management. In this role I traveled extensively throughout Central America and Mexico, and the Caribbean Islands, and helped to found and establish one of the most enduring and successful research partnerships between national research programs and any international agricultural research institute: PRECODEPA.

Then, just as I was thinking about a move to CIP’s regional office in the Philippines (for Southeast Asia), an entirely different opportunity opened up, and we moved back to the UK.

Back to Birmingham
In January 1981 I successfully applied for a Lectureship in my old department (now named the Department of Plant Biology) at Birmingham. I said goodbye to CIP in March 1981, and embarked on the next stage of my career: teaching botany.

The lectureship had been created to ensure continuity of teaching in various aspects of the conservation and use of plant genetic resources (and other topics) after Professor Hawkes’ retirement in September 1982. I assumed his particular teaching load, in crop plant evolution and germplasm collecting on the MSc Course, and flowering plant taxonomy to second year undergraduates, as well as developing other courses at both undergraduate and graduate level.

In addition to my continuing research interest on potatoes I assembled a large collection of Lathyrus species and one PhD student from Malaysia made an excellent study of species relationships of the one cultivated species, the grasspea, L. sativus. I successfully supervised (or co-supervised) the theses of nine other PhD students (and at least a couple of dozen MSc students) during the decade I spent at Birmingham.

I generally enjoyed the teaching and interaction with students more than research. Having struggled as an undergraduate myself, I think I could empathise with students who found themselves in the same boat, so-to-speak. I took my tutor/tutee responsibilities very seriously. In fact, I did and still believe that providing appropriate and timely tutorial advice to undergraduates was one of the more important roles I had. My door was always open for tutees to drop by, to discuss any issues in addition to the more formal meetings we had on a fortnightly basis when we’d discuss some work they had prepared for me, and I gave feedback.

While I appreciate that university staff are under increasing pressures to perform nowadays (more research, more grants, more papers) I just cannot accept that many consider their tutor responsibilities so relatively unimportant, assigning just an hour or so a week (or less) when they make themselves accessible by their tutees.

The 1980s were a turbulent time in the UK. Politics were dominated by the Tories under Margaret Thatcher. And government policies came to significantly affect the higher education sector. By the end of the decade I was feeling rather disillusioned by university life, and although I was pretty confident of promotion to Senior Lecturer, I also knew that if any other opportunity came along, I would look at it seriously.

And in September 1990 just such an opportunity did come along, in the form of an announcement that IRRI was recruiting a head for the newly-created Genetic Resources Center.

Dr. Klaus Lampe

A return to international agriculture
It was early January 1991, and I was on a delayed flight to Hong Kong on my way to the Philippines for an interview. Arriving in Los Baños around 1 am (rather than 3 pm the previous afternoon), I had just a few hours sleep before a breakfast meeting with the Director General, Dr. Klaus Lampe and his two deputies. Severely jet-lagged, I guess I more or less sleep-walked through the next three days of interviews, as well as delivering a seminar. And the outcome? IRRI offered me the position at the end of January, and I moved to the Philippines on 1 July remaining there for almost 19 years.

For the first ten years, management of the International Rice Genebank (the world’s largest collection of rice varieties and wild species) was my main priority. I have written about many aspects of running a genebank in this blog, as well as discussing the dual roles of genebank management and scientific research. So I won’t repeat that here. Making sure the rice germplasm was safe and conserved in the genebank to the highest standards were the focus of my early efforts. We looked at better ways of growing diverse varieties in the single environment of IRRI’s Experiment Station, and overhauled the genebank data management system. We also spent time studying the diversity of rice varieties and wild species, eventually using a whole array of molecular markers and, in the process, establishing excellent collaboration with former colleagues at the University of Birmingham and the John Innes Centre in Norwich, UK.

Dr. Ron Cantrell

Then, one day in early 2001, IRRI’s Director General, Dr. Ron Cantrell, called me to his office, asking me to give up genebanking and join the institute’s senior management team as Director for Program Planning and Communications. As I said earlier, I really enjoyed management, but wasn’t sure I wanted to leave research (and genetic resources) behind altogether. But after some serious soul-searching, I did move across in May 2001 and remained in that position until my retirement in April 2010.

Even in that position, my background and experience in the plant sciences was invaluable. All research project proposals for example passed through my office for review and submission to various donors for funding. I was able not only look at the feasibility of any given project in terms of its objectives and proposed outcomes within the project timeframe, I could comment on many of the specific scientific aspects and highlight any inconsistencies. Because we had a well-structured project proposal development and submission process, the quality of IRRI projects increased, as well as the number that were successfully supported. IRRI’s budget increased to new levels, and confidence in the institute’s research strategy and agenda gained increased confidence among its donors.

What a good decision I made all those years ago to study botany. I achieved that early ambition to travel all over the world (>60 countries in connection with my work) in North and South America, Europe, Africa, Asia, and Australia. But the study (and use) of plants gave me so much more. I used the knowledge and experience gained to help transform lives of some of the poorest farmers and their families, by contributing to efforts to grow better yielding crops, more resilient to climate change, and resistant to diseases.

I’m sure that a degree in botany would be the last in many people’s minds as leading to so many opportunities such as I enjoyed. Knowing that opportunities are out there is one thing. Seizing those opportunities is quite another. And I seized them with both hands. I never looked back.

I should also mention that I also ascribe some of my success to having had excellent mentors—many mentioned in this piece—throughout my career to whom I could turn for advice. Thank you!

Management and science – are they equally important roles for a genebank manager?

There’s an interesting article by Nicola Temple and Michael Major (science communications specialists for Scriptoria and the Crop Trust, respectively), on the Genebank Platform website, about Dr David Ellis who retired at the end of 2018 as head of the genebank at the International Potato Center (CIP) in Lima, Peru (where I began my career in international agricultural research in January 1973).

Titled David Ellis: Finding the balance between manager and scientist, the article describes David’s illustrious career, and highlights an important issue that many genebank managers face. Let me quote directly what they wrote:

David argues that genebank managers need to balance science with the management of their collections. “If you focus purely on the science, then management of the genebank suffers,” he says. “If you focus solely on being a genebank manager, then you are never viewed by your scientific peers as a research scientist and that can mean fewer opportunities for collaboration.”

His perspectives—which I fully endorse—resonated with me, and got me thinking about the time, almost 30 years ago, when I joined the International Rice Research Institute (IRRI) in the Philippines as Head of the newly-created Genetic Resources Center (GRC) with responsibility for (among other things) the internationally-important rice genebank, the International Rice Germplasm Center that, in the fullness of time, we renamed the International Rice Genebank. I was head of GRC for a decade, after which I changed roles at IRRI, and relinquishing all my genetic resources responsibilities.

A career in genetic resources
By July 1991, I’d already been working on the conservation and use of plant genetic resources for twenty years. I’d studied at the University of Birmingham under Professor Jack Hawkes and Professor Trevor Williams, and had forged a career at CIP (in Peru and Central America) for over eight years, before returning to Birmingham to join the faculty of the School of Biological Sciences (helping to train the next generation of germplasm scientists).

However, until joining IRRI, I’d never managed a genebank.

I first heard about the job at IRRI in September 1990, when a position announcement landed on my desk in the morning post. I was intrigued. Who had sent this to me? At the same time, the thought of running a genebank was rather attractive, because by 1990 I had become somewhat disillusioned with academic life.

The IRRI position represented an opportunity to return to international agricultural research that I had enjoyed during my years with CIP from 1973-1981.

As initially advertised, the Head of the Genetic Resources Center position was described merely as a service role with no assigned research responsibilities whatsoever. The Head would report directly to the Deputy Director General (International Programs)—not the DDG (Research).

On the positive side, however, the position would be equivalent to other Division Heads and Program Leaders giving the incumbent an opportunity to represent the genebank directly in institute management discussions.

Having sent in my application, I traveled to the Philippines in early January 1991 for an interview, and was offered the position three weeks later. During the interview(s), and in the subsequent negotiations to iron out the terms and conditions of my appointment, I made it a condition of accepting that I (and my future GRC staff) would have a research role. Indeed, without that commitment and support from senior management, I was not interested in the position. I can be persuasive. My viewpoint prevailed!

Learning about genebanking – on the job
Management and science are almost equally important roles. But not quite. Management and safety of any genebank collection (including making it available to users worldwide) must always be the top priority.

Dr TT Chang

Before 1991 there had been just one person—eminent rice geneticist and upland rice breeder, Dr TT Chang—as head of the genebank for about thirty years. Very quickly I realised that some important changes must be made, and the best known genebank practices and standards adopted. And that’s where I focused my efforts for the first three years of my tenure in GRC.

Initially I had to immerse myself in how the genebank was being managed, especially in terms of staffing needs and people management, and to develop a plan to make it run much more efficiently. That meant identifying and appointing staff to lead critical functions in the genebank like seed conservation, field operations (multiplication of genebank accessions and rejuvenation), characterization, or data management. Finding or assigning existing staff for the right roles.

What I did find was a highly motivated and professional staff who had never received any real guidance as to their roles, nor had they been given any specific responsibilities. As a consequence, productivity was rather low, as different members of staff overlapped in their day-to-day activities, sometimes at cross purposes.

It took me about six months to understand just how the genebank functioned, and how many operations needed to be updated. But I also had the tricky task of ‘side-lining’ the most senior of the national staff, Eves Loresto, from the line of communication to me from other staff members. She had been Dr Chang’s assistant, and nothing reached him from the staff unless it passed through her first. This was, I felt, an obvious obstacle to accomplishing the necessary changes to staff roles and productivity. Ultimately I found her an important role in leading various components of an externally-funded biodiversity project (by the Swiss government) that I couldn’t have managed on my own.

It took about three years, but we overhauled almost everything that the genebank did (and producing an important manual of genebank operations, something that all CGIAR genebanks are now expected to have). One of the key problem areas was data management, a complete nightmare, as I have described elsewhere on my blog.

We brought all field operations back on to the IRRI Experiment Station, and through investment in facilities, we were able to remodel and upgrade the genebank cold stores, the seed testing laboratory, and germplasm handling protocols for responding efficiently to requests for rice germplasm, in conjunction with the Seed Health Unit which handled all aspects of quarantine and phytosanitary certification for import and export of rice seeds.

We also made sure that the collection was fully duplicated at the USDA National Laboratory for Genetic Resources Preservation in Fort Collins, CO, an initiative that had begun under my predecessor, but needed acceleration.

By the time of the first CGIAR system-wide review of genebanks that was completed in 1994-95, IRRI’s genebank was rated as ‘a model for others to emulate‘. While IRRI did invest in the genebank (improved configuration of storage rooms, laboratories, seed drying, etc.), much of what we achieved in the genebank did not actually require much additional or even special funding. Just a realignment of the way the genebank operated. And a lot of hard work by great staff to make the necessary improvements. I can’t stress too much how important it was to have the staff onside, and spending much effort in people management, including having more than 70% of all positions in GRC upgraded and staff promoted.

You can see much of how the genebank operates in this video below. And while it’s true that my successor, Dr Ruaraidh Sackville Hamilton built on the improvements made during the 1990s, we achieved the current genebank standards, and this permitted IRRI to move to the next level and meet its obligations and performance targets under the current funding structure of the Genebank Platform.

As the staff grew into their roles in the genebank, there was more opportunity to reach out to national rice programs around Asia, as well in Africa and Latin America. We helped train a large cadre of national scientists in genebank data management and, to accompany germplasm collecting, we offered practical workshops. National programs then shared collected germplasm with IRRI, and the size of the International Rice Genebank Collection grew by about 25% between 1995 and 2000. Overall, there were 48 courses in 14 countries. For details, see the project final report.

Turning to research
In July 1991, GRC had essentially no research profile whatsoever. Just a few minor studies, tinkering around the edges of research. From 1994 or thereabouts, that all changed. We invested time, people, and funds to:

  • Study the effects of seed production environment and seed quality and survival in storage;
  • Understand the diversity of rice using molecular markers;
  • Clarify the taxonomy of rice species, primarily those most closely related to Oryza sativa, the rice grown widely around the world; and
  • Understand the dynamics of rice conservation by farmers from the joint perspectives of population genetics and social anthropology.

Because we started from such a low base, I decided to forge important collaborations with several research groups to kick-start our research efforts.

Dr Kameswara Rao

In terms of seed production (and seed conservation), we had an excellent collaboration with Professor Richard Ellis at the University of Reading in the UK. We also hired a postdoc, Dr Kameswara Rao (from ICRISAT in Hyderabad, India) to work at IRRI on these joint projects. Kameswara had completed his PhD at Reading under the supervision of Professor Eric Roberts. After leaving IRRI, Kameswara joined the genebank program at the International Center for Biosaline Agriculture in Dubai, UAE; he has since retired.

Dr Parminder Virk

The use of molecular markers to study crop diversity was in its infancy in the early 1990s, although as I pointed out in a recent blog post, a number of molecular approaches had been used during the 1980s and earlier in different labs. We partnered with my former colleagues at the University of Birmingham, Professors Brian Ford-Lloyd and John Newbury (now retired) and Dr Parminder Virk (who eventually joined IRRI as a rice breeder and is now with the HarvestPlus program in India), in collaboration with the late Professor Mike Gale’s group at the John Innes Centre in Norwich.

These were highly effective collaborations, and we also built up our in-house capacity by sending one of the GRC staff for short-term training at Birmingham (sponsored by the British Council) while developing a molecular marker laboratory in GRC.

We undertook all taxonomy research in-house, and hired Dr Lu Bao-Rong from China to lead this effort. We also assigned two staff full-time to the molecular and taxonomy research, and support staff as well.

The on-farm conservation research was one component of the Swiss-funded biodiversity project I referred to earlier. One scientist, Dr Jean-Louis Pham came to IRRI from the French public research institution IRD in Montpellier to head the on-farm group.

I think we accomplished a great deal in the decade I was in charge of the International Rice Genebank. We established a solid foundation to take the genebank forward over the next two decades. I have listed below most of the GRC publications that appeared during this period. Links to PDF files of many of the papers can be found here.

The molecular marker and genomics research was strengthened in 2001 (as I was coming to the end of my tenure in GRC) with the appointment of Dr Ken McNally.

Dr Ken McNally and Dr Fiona Hay

Around 2002 a seed physiologist, Dr Fiona Hay, joined GRC and although she has now moved to Aarhus University in Denmark, her research on seed drying and storage contributed significantly towards safeguarding this valuable germplasm collection.

Looking back on the 1990s, I think GRC can be proud of its research output. We did, as David Ellis proposed, establish our scientific credibility and, in a number of forums, took that message out to the wider scientific community and the public at large. Always, however, knowing that the genebank collection was safe for the long term, and available and accessible to everyone around the world who had need of germplasm to improve rice—which is, after all, the world’s most important staple crop.

Are you plant blind?

In our 1986 book Plant Genetic Resources: An Introduction to their Conservation and Use, my former colleague and friend of almost 50 years, Professor Brian Ford-Lloyd and I wrote (on page 1):

To most people the word ‘conservation’ conjures up visions of lovable cuddly animals like giant pandas on the verge of extinction. Or it refers to the prevention of the mass slaughter of endangered whale species, under threat because of human’s greed and short-sightedness. Comparatively few  however, are moved to action or financial contribution by the idea of economically important plant genes disappearing from the face of the earth. . . . But plant genetic resources make little impression on the heart even though their disappearance could herald famine on a greater scale than ever seen before, leading to ultimate world-wide disaster.

Hyperbole? Perhaps. Through our 1986 lens that did not seem far-fetched. And while it’s fair to say that the situation today is better in some respects than Brian and I predicted, there are new threats and challenges, such as global warming.

The world needs genetic diversity to breed varieties of crops that will keep agricultural systems sustainable, allow production of crops in drought-prone regions, where temperatures are increasing, and where new races of diseases threaten even the very existence of agriculture for some crops.

That genetic diversity comes from the hundreds of thousands of crop varieties that farmers have nurtured for generations since the birth of agriculture millennia ago, or in closely related wild species. After all, all crops were once wild species before domestication.

These are the genetic resources that must be safely guarded for future generations.

The work of the International Board for Plant Genetic Resources (IBPGR), then the International Plant Genetic Resources Institute (IPGRI), was pivotal in coordinating and supporting genetic resources programs worldwide, in the 1970s, 80s and 90s.

Then a new and very important player came along. Over the past decade and half the Crop Trust, has provided long-term support to some of the world’s most important genebanks.

International mechanisms have been put in place to support collection, conservation, study, and use of plant genetic resources. Yet, much remains to be done. And ‘Joe Public’ is probably still as unaware of the importance of the crop varieties and their wild relatives (and perhaps plants in general) as we feared more than three decades ago.


Wildlife programs on TV are mostly about animals, apart from the weekly gardening programs, and some such as David Attenborough’s The Private Life of Plants (broadcast in 1995). Animal programs attract attention for precisely the reasons that Brian and I highlighted in 1986. A couple of nights ago for instance I watched a fascinating, hour-long program on the BBC about hippos in the Okavango Delta of Botswana. Wonderful footage revealing never-before-seen hippo behaviour and ecology.

When it comes to genetic resources, animals don’t do so badly either, at least here in the UK. We get an almost weekly item about the importance of rare breeds of livestock and their imperiled status during the BBC’s flagship Countryfile program on Sunday evenings presented by farmer Adam Henson, whose father Joe helped set up the Rare Breeds Survival Trust (RBST) in 1973. The RBST has been pivotal in rescuing many breeds from the brink of extinction. Just last night (28 July) Adam proudly showed an Albion calf born the day before on his farm in the Cotswolds. The Albion breed is one of the rarest in the UK.

But that says very little about all the endangered livestock breeds around the world that are fortunately the focus of the work of the International Livestock Research Institute (ILRI).

However . . .

When was the last time—if ever—you watched a TV documentary about the rare (so-called ‘heritage’) varieties of the food plants on which we depend, or their closest wild species relatives, such as the barleys of Ethiopia or the potatoes of the South American Andes, for instance. And would you really care if you hadn’t?

Are you even aware that the barleys that we use for brewing originally came from Ethiopia and the Middle East? Or that the Spanish brought the potato back to Europe in the 16th century from Peru? What about your daily cups of tea or coffee?

These are just some of the myriad of fascinating histories of our food crops. Today many of these staples are often more important in agriculture in parts of the world far distant from the regions where they originated and were first domesticated.

In the UK, enthusiasts will be aware of heritage vegetable varieties, and the many varieties of fruits like apples that have disappeared from commercial orchards, but are still grown at places like Berrington Hall in Herefordshire.

Take a look at this article by freelance communicator Jeremy Cherfas about the origins of the food we eat. Jeremy has written a lot about genetic resources (and many other aspects of sustainable agriculture). As he says, you may discover a few surprises.

In centers of domestication, the diversity of the crops grown by farmers is impressive indeed. It’s wonderful. It’s BEAUTIFUL! The domestication of crops and their use by farmers worldwide is the story of civilization.

Here are just a few examples from beans, maize, cocoa, cucurbits, wheat, and lentil.

And take a look at the video below.

Who could fail to be impressed by such a range of shapes and colors of these varieties? And these varieties (and wild species) contain all the genes we need to keep crops productive.

Plant genetic resources: food for the stomach, food for the soul.


My own work since 1971 concerned the conservation and use of potatoes and rice (and some legume species as side projects).

In Peru, I came to learn just how important potatoes are for communities that live at altitude in the Andes. Could the Inca empire have grown and dominated the region had there been no potatoes (and maize)?

Machu Picchu

And there are so many wild species of potatoes that can be found from the southern USA to the south of Chile and east into the plains of Brazil. The International Potato Center (CIP) in Lima (where I worked for over eight years) has the world’s largest genebank of potato varieties. Important wild species collections are maintained there, as well as in Scotland at the Commonwealth Potato Collection (maintained by the James Hutton Institute), and the USA, at the NRSP-6 Potato Genebank in Sturgeon Bay, WI.

Rice is the food of Asia. There are thousands upon thousands of varieties that grow in standing water, or on sloping uplands, or in areas that flood and so have evolved to elongate rapidly to keep pace with rising flood waters.

Here is a selection of images of rice diversity in Laos, one of the countries that we explored during the 1990s.

Would it have been possible to build the temple complex at Angkor Wat in Cambodia in the 12th century without rice? It has been estimated that upwards of one million workers were employed in its construction. That workforce needed a constant supply of staple rice, the only crop that could be grown productively in this monsoon environment.

These potato and rice examples are the tip of the genetic resources and civilization history iceberg. Think about the origins of agriculture in Turkey and the Mideast, 10,000 years ago. Remains of wheat, barley and pulses like lentil and chickpea have been found at the earliest cities in that region. And these histories are repeated all around the world.


In 1983 and 1984, BBC2 aired two series of a program called Geoffrey Smith’s World of Flowers, in which Smith (a professional gardener and broadcaster) waxed lyrical on the history of many of his favorite garden plants, and their development in cultivation: tulips from Turkey, dahlias from Mexico, lilies from North America, and many, many more.

In these programs, he talked about where and how the plants grow in the wild, when they had been collected, and by whom, and how through decades (centuries in some cases) of hybridization and selection, there are so many varieties in our gardens today. The programs attracted an audience of over 5 million apparently. And two books were also published.

I had an idea. If programs like these could be so popular, how about a series on the food plants that we eat, where they originated, how they were domesticated, and how modern varieties have been bred using these old varieties and wild species. I envisaged these programs encompassing archaeology and crop science, the rise of civilizations, completing the stories of why and which crops we depend on.

I wrote a synopsis for the programs and sent it to the producer at the BBC of the Geoffrey Smith programs, Brian Davies. I didn’t hear back for several weeks, but out of the blue, he wrote back and asking to come up to Birmingham for a further discussion. I pitched the idea to him. I had lots of photos of crop diversity and wild species, stories about the pioneers of plant genetic resources, like Vavilov, Jack Harlan, Erna Bennett, and Jack Hawkes, to name just a few. I explained how these plant stories were also stories about the development and growth of civilizations, and how this had depended on plant domestication. Stories could be told from some of the most important archaeological sites around the world.

Well, despite my enthusiasm, and the producer warming to the idea, he eventually wrote back that the BBC could not embark on such a series due to financial limitations. And that’s all I heard. Nevertheless, I still think that a series along these lines would make fascinating television. Now who would present the series (apart from myself, that is!)?

Maybe its time has come around again. From time-to-time, interesting stories appear in the media about crops and their origins, as this recent one about cocoa and vanilla in the Smithsonian Magazine illustrates.

But we need to do more to spread the plant genetic resources ‘gospel’. The stories are not only interesting, but essential for our agricultural survival.


 

What’s wrong with ‘a bowl of alphabet soup’?

CGIAR? CG? CeeGee? Or should that be CIGAR?

The CGIAR is, it seems, a mystery to almost the entire world population, even those billions whose survival depends on the outputs of CGIAR-funded agricultural research. Recently, philanthropist Bill Gates wrote in his blog that . . . you’ve probably never heard of CGIAR, but they are essential to feeding our future. Fair comment.

Originally known as the Consultative Group on International Agricultural Research but more commonly just CGIAR today, it is the world’s largest global agricultural innovation network.

Founded in 1971, under the auspices of the World Bank, to coordinate international agricultural research efforts aimed at reducing poverty and achieving food security in developing countries, the network today supports 15 independent agricultural research institutes or centers. CGIAR brings evidence to policy makers, innovation to partners, and new tools to harness the economic, environmental and nutritional power of agriculture.

The centers carry out research on the world’s most import food crops (such as wheat, maize, and rice among many others), water and biodiversity management, livestock and fish, tree and forest systems, the dynamics of the world’s most challenging agricultural ecosystems, and food and agricultural policy.

Their research agendas contribute significantly towards the United Nations Sustainable Development Goals. And, of course, much of the research today is directed towards combating the threat (and challenges) of a changing climate that will affect agricultural productivity in most parts of the world in decades to come. In his blog piece, Gates rightly highlights the important climate-related research ongoing at two centers in Mexico and Nigeria, the International Maize and Wheat Improvement Center (CIMMYT) and International Institute for Tropical Agriculture (IITA), respectively. There’s more going on in the other centers coordinated through a cross-center research program.

Many billions of dollars have been invested in international agricultural research over the past 50 years or so. But the economic return through increased productivity has been many billions of dollars more.

But we shouldn’t just look at the economic benefits, important as they are. Millions upon millions of people have been taken out of poverty, and despite a worrying reversal of the favorable downward trend of food insecurity (due to economic slowdowns and downturns around the globe, as outlined in a recent report from several international agencies), more people benefit today from access to better crop varieties or improved practices. Many farmers can now afford to provide education opportunities for their children which they were unable to do without access to new technologies.

The centers supported through CGIAR are the key international players for conservation of genetic diversity found in farmer varieties and wild species of crop relatives. This genetic material or germplasm is safely stored in the genebanks at eleven of the centers. More importantly, this germplasm is being studied and used to breed better-adapted varieties.


When CGIAR was founded in 1971 there were already four centers, which were ‘adopted’ for funding support. The International Rice Research Institute, IRRI, based in the Philippines, is the oldest, founded in 1959 [1] and about to celebrate its Diamond Jubilee later this year.

Then came the Mexico-based CIMMYT in 1966 (although its antecedents stretch back to 1943 and a Rockefeller Foundation-funded program in Mexico), followed in 1967 by the International Center for Tropical Agriculture, CIAT, in Colombia and IITA, in Nigeria. Others followed over the next decade or so, but the number has fluctuated as centers merged, or even closed down.

I worked at two of these centers over a period of 27 years, as a junior/senior scientist in Peru and Central America at the International Potato Center or CIP that was founded in 1971 [2]; and as a Head of Department, then Director, at IRRI.


IRRI, CIMMYT, CIAT, IITA. Just four of the research institute acronyms that seemingly roll off the tongue. Yet, these very acronyms seemingly conspire to confuse. Even Bill Gates seems overwhelmed by center branding, stating that with so many acronyms being bandied about that the  . . . uninitiated feel[ing] as if they’ve fallen into a bowl of alphabet soup.

In the early years, CGIAR was an informal association of donor agencies that agreed to coordinate their funding to support the small numbers of centers that at one stage in the 1990s was allowed to grow to about 18 centers. At least one center closure and some mergers have come about since. And the funding model has changed.

Towards the end of the 1990s there was a growing concern among the donors of the centers—the members of CGIAR (centers are not members per se)—that there was too much duplication among centers in terms of their research programs, that their relationships with research programs in developing countries was burdensome for some of those programs, and that donor interests were not being met. Twenty years on, and despite changes to the funding model whereby donors have much more control over research projects in the centers, and the development of cross-center programs (with all the transactions paraphernalia that comes with these, such as meetings across continents, performance targets, and the added costs of just doing business), the profile of CGIAR remains weak (if we accept Bill Gates’ line of argument).

Why can that be, despite the intensive efforts to remedy this situation. In 1998 the centers supported by the CGIAR created Future Harvest as a charitable and educational organization designed to advance the debate on how to feed the world’s growing population without destroying the environment and to catalyze action for a world with less poverty, a healthier human family, well-nourished children, and a better environment.

It was a doomed rebranding initiative from the outset, yet survived several years. Centers were branded as members of the Alliance of Future Harvest Centers, a branding that has all but disappeared. It’s almost impossible to find any reference to Future Harvest on the web, and I only came across one logo on the inside of one publication. One of the reasons why Future Harvest failed is that while the concept was probably fine for the English-speaking world, it found no counterpart in Chinese, Hindi, Bahasa Indonesia, Swahili, or whatever. Future Harvest? What does that mean?

But it started, in my opinion, from a lack of understanding (misunderstanding, perhaps) of the power of branding of the individual centers. CGIAR (Future Harvest) is the sum of its parts, the independent centers that actually do the research. IRRI is a more powerful, and known, brand in Asia in particular [3]. The same goes for CIMMYT in Mexico, India, and Pakistan, and for the other centers where they operate.

Yes, the initiatives to permit centers to align their agendas and work more closely are worthwhile. But at the outset, the funding model was such that centers found themselves having to bid to become members of the new system programs, just to survive. Not a good reason for inter-center collaboration.

I have no problem with Gates’ bowl of alphabet soup. Fifteen acronyms (that you can actually pronounce) is a small price for strong branding, as long as full names are explained as well. This situation is no different from what you can find in any country. Just take the UK: NIAB (National Institute of Agricultural Botany in Cambridge); JIC (John Innes Centre in Norwich); or JHI (James Hutton Institute, in Dundee and Aberdeen). No-one seems perturbed recognizing these prestigious institutions either by their acronym or name. Why should there be any difficulty for the centers supported by CGIAR?

In response to Gates’ blog post, one tweeter (who had worked at one of the centers, CIMMYT I believe) stated that this ‘confusion’ was a sound justification for merging centers into one institute. I couldn’t disagree more. The strength of CGIAR lies in its diversity. Centers are strategically located around the world. Institutional (and national staff) cultures and set ups are very different. Doing business over time zones is problematical.

Merging organizations is never easy. One ‘partner’ inevitably loses out to another (take the Delta-NWA merger; who now remembers NWA?) One successful merger among CGIAR centers led to the creation of the International Livestock Research Institute or ILRI (bringing together the International Laboratory for Research on Animal Diseases in Nairobi, and the International Livestock Centre for Africa in Addis Ababa). Not all mergers or alliances prosper however. Closer links between IRRI and CIMMYT in the in the early 2000s came to nothing despite best efforts, and having two Board of Trustees members common to both. It remains to be seen how closer links between Bioversity International in Rome and CIAT, or the World Agroforestry Centre in Nairobi and the Center for International Forestry Research, or CIFOR in Bogor, Indonesia, pan out.

As you can see I’m a believer in the power, and identity, of the centers. After all, that’s where the research is planned strategically, where the scientists reside, and where they do their work. Branding is important and can make all the difference for delivering the right message.

Let’s celebrate how CGIAR has supported international agricultural research for almost five decades and continues to provide the framework for that to continue. Yes, the world needs to know and understand the importance of CGIAR and what it stands for. Equally, I would argue, let’s celebrate the work of IRRI, CIMMYT, IITA, CIAT, CIP, IFPRI, Bioversity International, ICARDA, IWMI, ILRI, World Agroforestry, Worldfish, CIFOR, ICRISAT, and Africa Rice.


[1] A Memorandum of Understanding was signed in December 1959 between the Government of the Philippines and the Rockefeller and Ford Foundations to establish IRRI. The Board of Trustees met in April 1960 to approve the institute’s constitution and by-laws. Thus, IRRI has two ‘birthdays’. The 50th anniversary was celebrated on 9 December 2009 and 14th April 2010.

[2] I was originally due to join CIP in September 1971, when I completed my MSc, and the CIP Director General, Richard Sawyer, had approached the forerunner of the UK’s Department for International Development for funding to support my assignment in Peru. But the UK was at that very moment deciding whether to fund CIP bilaterally or join CGIAR and fund the center’s work that way. My departure for Peru was delayed for 15 months.

[3] In about 2004, I was invited to a meeting on biotechnology and intellectual property rights in Malaysia, near Kuala Lumpur. My flight from Manila arrived in KL around 11 pm, and I had to take a taxi to the resort where the meeting was being held, about 35 km or so. I don’t remember if a taxi had been sent for me, or I just took the next one in the rank outside the terminal building exit. On the journey, the driver started asking me a few questions, and when I told him I worked in agriculture in the Philippines, he replied: ‘I guess you must work at IRRI’ or words to that effect. He knew all about IRRI. Notwithstanding he had once been a driver for Malaysia’s Minister of Agriculture, he was indeed very knowledgeable about rice and IRRI’s role. I was more than surprised.

 

Turbocharging rice photosynthesis – the vision and legacy of John Sheehy, a brilliant scientist

Yesterday, I received the sad news that my dear friend and former colleague at the International Rice Research Institute (IRRI), John Sheehy, had passed away on 7 June after battling Parkinson’s Disease and Multiple System Atrophy (MSA) for several years. He was just 76.

I first met John in 1995, when he applied for the position of Systems Modeller at IRRI. I was Chair of the Search Committee. John came to IRRI after a successful career at the Grassland Research Institute (GRI) in Hurley, Berkshire, until it closed in 1992. His groundbreaking (and award-winning) work at GRI on nodulation, gaseous diffusion, and nitrogen fixation in grassland legumes, and other aspects of crop physiology focused on yield potential.

I knew the first time I spoke with John he was someone who would bring a very different scientific perspective to IRRI’s research. And that’s just what he did. He wasn’t some fresh-faced graduate or postdoc expected to toe the line in terms of rice science orthodoxy, so to speak. Always polite, he often challenged the perspectives and approaches of some IRRI old timers who couldn’t (or wouldn’t) appreciate John’s breadth of quantitative expertise. He had graduated with a BSc degree in Physics, completed an MSc in Electronics, and then studied for his PhD in ecophysiology under Professor John Cooper, CBE FRS at the Welsh Plant Breeding Station in Aberystwyth.

In coming to IRRI, he led research on and supported breeding the so-called New Plant Type (NPT) that was expected to push the yield barrier in rice.

Setting up the Applied Photosynthesis and Systems Modeling Laboratory, John came to the conclusion that a completely new approach was needed if rice yields were to be increased significantly. That’s because photosynthesis in rice (known as C3 photosynthesis) is inefficient compared to the system (C4) in other cereals like maize. John began to develop ideas to turbocharge photosynthesis by introducing ‘C4’ traits into rice, thereby aiming to increase photosynthetic efficiency by 50%, as well as improve nitrogen use efficiency, and double water use efficiency.

Rather than me trying to explain the rationale for this vision, why not listen to John explaining the need for a C4 rice.

John appreciated that IRRI could not realize this dream of a C4 rice alone. So he set about persuading, and bringing together, a group of many of the best scientists worldwide in a C4 Rice Project, that is partly funded by the Bill & Melinda Gates Foundation. The continuing Project is an important part of John’s scientific legacy.

It is now coordinated by Professor Jane Langdale, CBE FRS at the University of Oxford.

At the time of his death, and after 20 years of research, C4 rice is not yet a reality, but significant progress has been made.


John’s scientific output was prodigious, and his many publications appeared in some of the best rated journals in his field, like Field Crops Research for example, a reflection of his research stature at IRRI (and before he joined IRRI). You can check his publications on Google Scholar.

He also waded enthusiastically into the controversy over the System of Rice Intensification or SRI, questioning—based on solid quantitative analysis of yield potential in rice—the yield claims of SRI adherents.


John retired in 2009 and returned to the UK. Before leaving IRRI, he met with Gene Hettel (former Head of IRRI’s Communication and Publications Services, and ‘IRRI Historian’) to record his thoughts on rice science and the challenges that IRRI would face.


In 2012, John was recognized in the New Year Honours (see page N.24) with an OBE for services to agricultural research and development, which was conferred during an investiture at Buckingham Palace on 14 February.

In July 2014, John was honoured as a Fellow of his alma mater, Aberystwyth University.


In 2011, Steph and I joined John and Gaynor’s many friends and relatives to celebrate their 40th wedding anniversary.

L-R: Rhiannon, Gaynor, John, and Isabel

While at IRRI, John had taken enthusiastically to golf, and could be seen almost every weekend out on the golf course south of Los Baños where he had become a member. On his retirement to the UK, he was unfortunately unable to continue with this passion, due to bouts of poor health.

After I retired in 2010 back to the UK, John and I kept in touch regularly by email, on the phone, or SMS, when either Wales or Ireland were doing well at rugby, especially in the Six Nations championship. He had divided loyalties, born in Wales of Irish ancestry.

The last time I saw John was in July 2017, when Steph and I spent the weekend with him and Gaynor in Marlow, and met up with other IRRI friends, Graham and Sue McLaren (who now reside in Canada),

L-R: Gaynor, Graham, Sue, Steph, John, and me.

It was also an opportunity for John and me to swap OBE investiture reminiscences. I had also been made an OBE in the same New Year Honours as John, but attended an investiture two weeks later on 29 February.


John was a far better scientist than I could ever aspire to be. I always sought his advice on science issues. In return, he asked my advice about how to manoeuvre through institute politics and management to influence his research agenda, especially after I had moved upstairs, so to speak, to join IRRI’s senior management team.

But what I remember most about John was his cracking, but rather dry, sense of humor. His generosity of spirit. He was an excellent host. Many’s the dinner or BBQ Steph and I enjoyed with John, at his house or ours.

Christmas Day 2006 Chez Sheehy. L-R: John, Sue McLaren, Steph, Catherine McLaren, me, Gaynor, Alex McLaren, and Graham McLaren.

John, you will be sadly missed. Rest in Peace!

Everyone’s a taxonomist

I’ve just discovered (via Twitter) that 19 March was Taxonomist Appreciation Day. This was, as far as I can make out, a celebration of the important—fundamental even—contribution that biologists known as taxonomists make to our understanding of the living world. Taxonomists bring order to the biodiversity that’s all around us. Indeed, without this order and understanding, it would be more difficult to know for example which plants and animals are endangered, and to prioritize what to conserve, and where.

The most celebrated taxonomist of all was surely the eighteenth century Swedish botanist Carl von Linné (whose Latinized name, Linnaeus, identifies him as the taxonomic authority, L., for many plants and animals).

So what do taxonomists do? One of their important roles is to describe and catalogue all plants and animals and, in the case of plants, publish this information in compendia known as Floras as an aid to identification, like those written about the plants of the British Isles and Europe that have been studied for hundreds of years.

Other Floras are still being written. Take the Flora Zambesiaca, for example, a project started in 1960 as the taxonomic study of native and naturalised plants of the Zambezi River basin, covering the territories of Botswana, Malawi, Mozambique, Zambia, Zimbabwe and the Caprivi Strip. This is a work in progress, and there are many other parts of the world where the diversity of plants is only now being discovered and documented, particularly in the Tropics.

But taxonomists also look at the variation within species, and assess the dynamics of species distribution and evolution.


Mr Les Watson

I had my first taste of taxonomy at the University of Southampton where, as first year students or freshmen in 1967/68, we studied the diversity of flowering plants under the tuition of taxonomist Les Watson. He and another colleague Alan Myers took us to the west coast of Ireland for a field course in July 1968 where we studied the vegetation of the Burren in Co Clare.

Professor Vernon Heywood

In my final or senior year in 1970, I sat in on a plant taxonomy course given by eminent taxonomist Professor Vernon Heywood from the University of Reading (Les Watson had moved to Australia in 1968/69, and had not been replaced in the Department of Botany). I met up with Professor Heywood in 1991 at a conference in Rome where we had an opportunity to reminisce about that course.

I never expected that, one day, I would engage in taxonomic research. However, I never participated in describing or naming plant species, nor undertaking the enormous task of contributing to Floras that is sometimes considered the be-all and end-all of taxonomists’ work. I take my hat off to those taxonomists who write Floras, often relying on dried herbarium specimens of plants collected in nature. Nevertheless, in my own work, I have used herbaria on occasion, and twice spent time looking at specimens of lentil (Lens culinaris Medik.) and grasspea (Lathyrus sativus L.) among the millions of herbarium sheets curated in the Herbarium at the Royal Botanic Gardens at Kew. My interest was in the relationships of these cultivated plants and their wild relatives.

Comparing notes in the field in the Andes of central Peru with potato taxonomist Professor Jack Hawkes (who supervised my PhD dissertation).

In 1973 I joined the International Potato Center in Peru as an Associate Taxonomist, studying the evolution of cultivated potatoes. Biosystematics, a sub-discipline of plant taxonomy, was my field, and I investigated species relationships through field experiments to understand patterns of morphological variation, through breeding experiments, and cytogenetic analysis of chromosome pairing in hybrids, among other several different approaches.

When I returned to Birmingham in 1981 as Lecturer in Plant Biology, I continued research on wild potatoes, and also several legume species. I also contributed about half the lectures to a second year module on flowering plant taxonomy.

On moving to the International Rice Research Institute (IRRI) in the Philippines in July 1991, my colleagues and I delved into the taxonomy and species relationships of the two cultivated species of rice, Oryza sativa L. and O. glaberrima Steud., and the 20 or so wild species in the genus Oryza. We published quite extensively, and you you can peruse a list of rice publications (many with PDF files) here.


Just last week I met up for lunch with six retired former colleagues from the School of Biological Sciences at the University of Birmingham: three plant scientists (including me), three geneticists, and a zoologist. Inevitably we began to discuss not only the administrative and organization changes that had occurred at the university (I taught there between 1981 and 1991), but how the teaching of biology had also changed, and the topics that now form a core biology curriculum.

Back in the day, whole organism biology still formed an important component of an undergraduate degree in biological sciences at Birmingham. Nowadays, and for obvious reasons, there’s much more focus on molecular biology, and recent hirings in what is now the School of Biosciences (Biological Sciences and Biochemistry merged some years back) reflect that change of emphasis.

Alas, it’s no longer possible to study at Birmingham for a biology degree with a plant sciences focus. But that’s not just a Birmingham issue; it’s nationwide. And taxonomy is perhaps the discipline that has suffered more than most. Taxonomists are just not coming through the system. Just at the time when one can argue there should be more demand for taxonomists than ever before, given the environmental changes that threaten the world’s vegetation. In some regions we may be losing species even before they have been identified. Harvard biologist EO Wilson wrote this in 2017: Our incomplete taxonomic knowledge impedes our attempts to protect biodiversity. A renaissance in the classification of species and their interactions is needed to guide conservation prioritization [1].


Now, I started this piece stating that everyone is a taxonomist. Is that a fair assumption?I think so.

Appa Rao collecting upland rice varieties from a farmer in the Lao PDR.

Taxonomy (and classification) is a fundamental human characteristic, something we do every day. We sort the complex world around us into meaningful categories, and we give them names. In many societies, farmers and their husbands use so-called ‘folk taxonomies’ to manage the various crops grown, and often the diversity of different varieties within a crop. I have myself talked to potato farmers in the Andes of southern Peru about their cultivation of different varieties, and why these are grown in different ways. In the Lao PDR, with my colleague Dr Appa Rao, we looked at how farmers name all their rice varieties.

Even before talking to my second year students about flowering plant taxonomy as such (and the different approaches used to study variation), I asked them to practice some simple taxonomies on themselves: males vs. females, blondes vs. brunettes, spectacle users vs. non-users, for example. These are discrete characteristics, binary, one or the other. Then we’d look at the complexity of coping with characters that vary quantitatively, such as height, length, etc.

Fortunately, there are many numerical techniques that allow us to cope with all sorts of measurements, and reduce complexity to a state that can be interpreted more easily.

The classification of different rice species based on the measurement and analysis of a range of morphological characters.

The use of different molecular markers now allows us to refine taxonomies built using morphological data. But, as I once read in a letter published in a scientific journal, a professor of taxonomy decried the lack of basic species knowledge among many students using molecular approaches. They could wax lyrical, he stated, about the value of different molecular techniques, but they had hardly looked at a living plant. That brings me back to my concern about the reduction in teaching whole organism biology.

As I say, we are all taxonomists, one way or another. Unfortunately I don’t see any scientific expansion (in the UK at least) in this particular discipline.

The situation may be different in North America. Plant sciences are still very strong in many US universities, and indeed there is a bill before Congress that promotes botanical research & sciences capacity, generates demand for native plant materials, & authorizes related federal activities.

Around the world in 40 years . . . Part 23: An Anglo-Italian connection

I’ve twice traveled by train, in 2004 and 2006, from my home in Bromsgrove in northeast Worcestershire to Rome in central Italy. And if I had my way, I’d travel everywhere by train, if that were possible.

When visiting government agencies that provided financial support to the International Rice Research Institute (IRRI) when I was Director for Program Planning & Communications (DPPC), I tried to combine as many visits into a single trip as possible, thus making the best use of my time on the road. In Europe, traveling by train was by far the most convenient (and comfortable) way of visiting several cities on the way, rather than hopping on and off planes for relatively short flights. Not to mention the inconvenience of additional waiting time at airports and the hassle of actually getting to and from them.

Train travel in many European countries is reliable and, compared to the UK, competitively priced. Purchasing a Eurail pass was by far the cheapest option, even for First Class tickets, and could be bought online from the Philippines.

This was my itinerary on both occasions:

  • Bromsgrove – Birmingham New Street – London Euston (into Birmingham on London Midland—now operated by West Midlands Trains—then Virgin Trains to London; around 2 hours or so; map)
  • London Waterloo (Eurostar now operates from London St Pancras) – Brussels Midi (on Eurostar; around 2 hours; map)
  • Brussels Midi – Cologne – Bonn Central (on the Thalys to Cologne, and Deutsche Bahn, DB; just over 2 hours; map)
  • Bonn Central – Basel – Bern (Deutsche Bahn to Basel, then Swiss Federal Railways, or SBB/CFF/FFS), along the Rhine Valley (around 5½ hours; map)
  • Bern – Milan Central (on Swiss Federal Railways; around 4½ hours; map)
  • Milan Central – Rome Termini (on Trenitalia; 3 hours; map)

On the second trip I traveled with IRRI Director General Bob Zeigler (and his wife Crissan) to visit donor agencies in Brussels (Directorate General for International Cooperation or DGCI of Belgium, and the European Union, EU), the Federal Ministry for Economic Cooperation and Development (BMZ) in Bonn, the Swiss Development Cooperation (SDC) in Bern (and a side trip to Basel where Bob gave a seminar at the Syngenta Foundation), and finally, the International Fund for Agricultural Development (IFAD, an agency of the United Nations) in Rome – all members of the Consultative Group on International Agricultural Research or CGIAR.

Crissan and Bob Zeigler


We met at London’s Waterloo station for the Eurostar service to Brussels, arriving there mid-afternoon. Since no meetings had been arranged that same day, we enjoyed the warm afternoon sunshine for a stroll around La Grand-Place (a UNESCO World Heritage Site), before enjoying our dinner at one of the many cafes close by.

Bob and Crissan feasted on one of the local delicacies: moules (mussels).

I like mussels, but in moderation, just a few added to a fish pie or a fish soup. Not a whole meal. In any case, our meal was accompanied, of course, by several glasses of excellent Belgian beer.


The day after our meetings, we caught the Thalys (the Belgian TGV) to Cologne, and then a regional service for the short hop to Bonn. We had just one day of meetings in Bonn, with the German aid ministry (BMZ), and then spent an excellent day touring the vineyards of the Ahr Valley just south of Bonn. Our main contact was my old friend Marlene Diekmann who I’d known for many years before she joined the BMZ when she was a plant pathologist at the International Plant Genetic Resources Institute (IPGRI, now Bioversity International) in Rome.

On previous visits to Bonn, in all weathers, Marlene and I had gone walking along the terraces of the Ahr Valley, as I described in this blog post. On this current trip with the Zeiglers, as in the past, we sampled some of the fruits of the vintner’s art. And very good it was.

Each time I have visited the Ahr Valley I have never failed to be impressed at the cultivation of the vines on such steep slopes. In the early evening we headed to Rheinbach (map) to join Dr Hans-Jochen de Haas, who was Germany’s representative to the CGIAR, and became a good friend.

I’d last seen him the previous year in Bonn and presented him with a book on rice culture.

A few years later (and before I retired in 2010) he sadly passed away after contracting Creutzfeldt-Jakob disease or CJD.

Bob and I (with Marlene) also made a one-day visit to Hannover (again by train) to visit the Volkwagen Foundation to try and tempt them to support a research project on rice and climate change involving a German scientist seconded to IRRI.

Commitments in Germany completed, Switzerland was our next stop, so we took the train along the River Rhine to Basel, and transferring to Swiss railways to Bern.


I first visited Switzerland in July 1984 when I attended the 9th Triennial Conference of the European Association for Potato Research (EAPR), that was held in Interlaken in the heart of the Bernese Oberland.

A group of us from the UK flew from London Gatwick to Bern (Switzerland’s capital city) on a Swissair BAe 146, and then taken the train for the 1 hour rail journey to Interlaken. There are no flights to Bern nowadays; Switzerland is served by two major international airports in Geneva (in the west) and Zurich (in the north central part of the country). And, in any case, rail services across the country are frequent, convenient, and comfortable.

In 1984, I’d taken a trip up to Wengen (1274 m) from Interlaken, with the last leg on the funicular railway from Lauterbrunnen. The Zeiglers and I repeated this trip. And after lunch in Wengen, we took the cable car up to Männlichen (2343 m), before dropping to Grindelwald (1034 m) on Europe’s longest gondola cableway (and third longest in the world).

At Männlichen there are fabulous views of the Eiger, Jungfrau and other mountains.

Watch this video that I found on YouTube of the cable car ride to Männlichen and the gondola cableway down to Grindelwald.

All too soon, our Swiss visit was over, and we took the train to Milan, an impressive journey through the Alps and the Italian lakes.

In Milan, we transferred to the high speed train to Rome. That was an interesting journey. In 2006, the 18th FIFA World Cup was hosted by Germany. Although Mexico had been eliminated from the competition by then, our train was full of supporters from Mexico on their way to Rome to enjoy the sights. Bob, Crissan and I all spoke Spanish. Bob and Crissan had actually lived in Mexico for a few years before returning to IRRI in 2005. So we had a great time with the Mexicans, and our fast train journey to Rome (a city I have visited numerous times) passed even faster it seemed.


 

Around the world in 40 years . . . Part 22: Iberian capitals

As Director for Program Planning and Communications (DPPC, from 2001 until my retirement in 2010) at the International Rice Research Institute (IRRI), I managed the institute’s portfolio of research projects, reporting back to donor agencies on progress and outcomes, such as the UK’s DFID, USAID in the USA, or the SDC in Switzerland, to mention just three. And working with them to ensure continued financial support to the institute each year.

On a rolling basis, I tried to meet officials from these agencies on their home turf, so to speak, and would coordinate several meetings in a single trip. I often scheduled meetings with European donor agencies when I was back on leave in the UK each year. And this was the case in early July 2003 when I visited Portugal (Lisbon) and Spain (Madrid).


At that time, one of my IRRI colleagues, Dr Swapan Datta, had a joint research project with Professor M. Margarida Oliveira of the Instituto de Tecnologia Química e Biológica António Xavier (ITQB), a scientific research and advanced training institute of the Universidade NOVA de Lisboa in Portugal. One of her students, Marta Vasconcelos, worked on rice biofortification with ferritin in Datta’s lab. Another, Sónia Negrão, worked with IRRI’s plant breeders for part of her PhD study, and held a post-doctoral fellowship at IRRI as well.

On the beach at Oeiras close to ITQB, with Margarida, Marta, and Sonia (in the left image) and Sonia and Marta (right).

Prof. Oliveira and I visited the Portuguese overseas aid agency to seek funding for joint rice projects. Portugal, at that time, provided only a small amount of funding (if any—I don’t remember the details) to IRRI. I also got to see some rice growing at the ITQB experiment station.

During the visit to ITQB, I gave a seminar about the genetic resources of rice and, with the donor visit, most of my second day in Lisbon was quite full. But, as was often the case in visits to donor capitals, there also was an opportunity for some sight-seeing.

I had arrived to Lisbon the day before, in the early afternoon. After settling into the Hotel Lutécia in the Areeiro district (map), north of the city center, I decided to see what Lisbon had to offer and took the metro to the city center, about a 20 minute ride from the Roma-Areeiro station to the Baixa-Chiado station.

Lisbon is a lovely maze of narrow streets, and large open plazas. One thing that immediately struck me, especially from the heights of the Castelo de S. Jorge, were the orange tile roofs of all the houses spread over the surrounding hills, and the views over the Tagus River, and west to the expanses of the Atlantic Ocean.

Anyway, I made my way from the metro, south along Rua Agustina (mostly traffic free) full of designer shops and cafes and restaurants towards the Praça de Comércio.

And although I’d intended to carry on walking around the city, I did something I’d never done before. Seeing a line of double-decker open top buses to one side of the plaza, I decided to take a city tour. Having only a short time in Lisbon I realized this would be the best way of seeing much of the city.

The tour lasted about two hours, and I certainly saw many of the important sites, some of which I went back to explore on foot afterwards.

The tour took in: Praça da Figueira; Praça D. Pedro IV; Praça da Restauradores; Av. da Liberdade; Praça do Marquês de Pombal; the view down to the coast from the Alameda Cardeal Cerejeira; west to the Torre de Belém; and back to the city center via the Praça do Império and the magnificent Mosteiro dos Jerónimos, passing under the impressive  Ponte 25 de Abril over the Tagus.

Although it was getting on in the afternoon, I decided to walk up to the Castelo de S. Jorge and enjoy the views over the city.

Castelo de S. Jorge from Praça da Figueira (L) and the plaza from the castle (R).

Then, it was back down to enjoy a beer or three and a dish of bacalhau (a typical dish of cod), before heading back to my hotel.

On the second evening I decided to stay near my hotel, write up my notes, and get ready for a mid-morning departure to Madrid the following day.


I had just a couple of nights in Madrid. I’d been through the city’s airport in 1981 on my way to the Canary Islands. That was in June, and I remember stepping outside the airport terminal building to experience the heat. It was over 40ºC. Now, I’d lived in the tropics for over eight years up till then, but I’d never experienced heat like that.

In July 2003 it was pretty hot as well. I arrived mid-afternoon on my flight from Lisbon. I was booked into a boutique hotel near Real Madrid’s Santiago Bernabéu Stadium. By the time I was settled into my hotel, it was late afternoon, and fortunatley it was cooling down. So I took the metro to the Puerta del Sol plaza.

I wandered along the Calle Mayor, taking in the Plaza Mayor and Plaza de la Villa on my left, on on towards the Catedral de Santa María la Real de la Almudena and the Palacio Real.

Nearby there was a cafe where I could sit outside and enjoy a cold beer, before I headed back towards the Puerta del Sol plaza to choose a restaurant for my evening meal. Then it was back on the metro to my hotel.

I had meetings the next day, all day at the Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA) in the Moncloa-Aravaca district, northwest of the city center.

In the evening I chose a small restaurant close to the hotel. Excellent food!

Then, early the next day, it was off to the Madrid-Barajas Adolfo Suárez Airport, and an Iberia flight to Switzerland (Zurich), where I had a meeting in Bern at the SDC.

Before heading back to BHX, I visited old friends in The Hague, Gordon and Joan MacNeil. Gordon had been IRRI’s Deputy Director General for Finance, and left the institute in 2002.

All in all, an enjoyable trip, but not very fruitful donor-wise, unfortunately.

In 2012, Steph and I had a short holiday in Portugal, visiting my eldest brother Martin and his wife Pauline who live about 100 km north of Lisbon.


 

Around the world in 40 years . . . Part 21: Taking in Tokyo (and Tsukuba)

I recently wrote about a trip to Bali in 2005 when the IRRI Board of Trustees (BoT) held one of its biannual meetings there.

Four years later, in September 2009,  Steph joined me when I attended the BoT meeting in Japan that was held in Tsukuba, the science city just over 60 km or so northeast of Tokyo, followed by a couple of days in Tokyo itself. Since  the meeting was held in the week before Steph’s 60th birthday, we decided to stay on an extra couple of nights and see something of Tokyo. I had been in Tokyo just once before¹, around 1994; Steph had never visited. However, we’d both passed through Tokyo’s Narita airport many times while flying to the USA.

In the good old days, before Northwest Airlines merged with and was taken over by Delta. Narita was a major hub for NW flights to and from the USA, as is the case now with Delta.

Leaving Manila for Tokyo on the early morning flight (a very early start from Los Baños to check-in three hours ahead of the flight) was not without its challenges, and we weren’t entirely certain we’d be able to fly. The Philippines had been hit the day before by Typhoon Ketsana (known in the Philippines as Ondoy), the first of two typhoons to hit the country within one week. There was extensive flooding in parts of Manila (which we saw as the Delta 747 climbed out of the city). At Manila’s Ninoy Aquino International Airport or NAIA there was chaos at the check-in and in the departure areas. Many flights had failed to leave the previous day, and with so many passengers with nowhere else to go, the airport was heaving with people hoping to get a flight out.

Since Steph was traveling with me, I used air miles to upgrade our booking to Business Class as a special treat. The flight to Narita takes four hours. On arrival at Narita, we had a short wait for the bus to Tsukuba, around an hour northwest from the airport. We stayed at the Okura Frontier Hotel (the square building on the right) in the center of the city.

The Board and IRRI Management (and scientists as needed) met for three and a half days at the Tsukuba International Conference Center (just over a five minute walk south from the hotel).

Meanwhile, Steph joined the other spouses for several excursions in the surrounding region, as well as into Tokyo, to visit markets, see local handicrafts, take part in traditional Japanese flower arranging, a tea ceremony, and the like.

Then, after four days in Tsuskuba, we all decamped to central Tokyo, to the the Sheraton Miyako Hotel where, close-by, several events were organized by IRRI’s Japanese partner organization, the Japan International Research Center for Agricultural Sciences or JIRCAS.

As I mentioned earlier, Steph and I stayed on for an extra couple of nights, so we could explore parts of Tokyo at the weekend, on Saturday 3 October, departing for Manila on the Sunday evening flight.

I’ve marked the places we visited on the map below.

We took full advantage of the extensive Tokyo subway system. We were able to purchase day tickets that gave access to the whole of the Tokyo subway system, over both the Toei Line and the Tokyo Metro Line. However, our first challenge was to purchase two tickets using the ticket machines. Eventually a very kind Japanese gentleman saw we were having a little difficulty, and helped us successfully navigate the menu.

Starting at Shirokanedai Station (station I02, center bottom left on the map) on the Mita Line (Toei Line system), we traveled to the commercial district of Akihabara (I08), well known for its many electronics outlets. From there we visited Hibiyakōen (via Hibiya station, I08/H07), a park (near the Imperial Palace) where an agricultural exhibition was being held, that also featured a booth for the Consultative Group on International Agricultural Research (including IRRI). Then it was on to the Shinjuku Gyoen National Garden (via Shinjuku-Gyoemmae station, M10), and back to the hotel.

One thing struck us quite forcefully during this day excursion: how quickly one could get away from the hustle and bustle of Tokyo at the Shinjuku Gyoen National Garden. It was a haven of peace and tranquility. Early October was perhaps not the best time of the year to see the garden. But it was lovely, nevertheless, and being enjoyed by locals with their families, although not at all busy.

Here is a 17 minute video that I made of the day.

One day is surely not enough to explore a city the size of Tokyo, but we did get to visit three areas that we had chosen. Getting around Tokyo was much easier than I anticipated, and more so than I remembered from my visit in the 1990s.

Of course there are many other places in Japan that we never had the opportunity and maybe one day we will return. The only other city I have seen—from the airport constructed on an artificial island—is Osaka.


¹ During that trip, when I was hosted by a former member of IRRI’s Board of Trustees, and another who was currently serving on the Board, I visited both Tsukuba and Tokyo. In  Tokyo I met officials at the Ministry of Agriculture, Forestry, and Fisheries (MAFF), and there I came across one of my former students, Yoshi Nishikawa, who attended the University of Birmingham plant genetic resources MSc course in 1987-88.
