Outside the EU . . . even before Brexit

Imagine a little corner of Birmingham, just a couple of miles southwest of the city center. Edgbaston, B15 to be precise. The campus of The University of Birmingham; actually Winterbourne Gardens that were for many decades managed as the botanic garden of the Department of Botany / Plant Biology.

As a graduate student there in the early 1970s I was assigned laboratory space at Winterbourne, and grew experimental plants in the greenhouses and field. Then for a decade from 1981, I taught in the same department, and for a short while had an office at Winterbourne. And for several years continued to teach graduate students there about the conservation and use of plant genetic resources, the very reason why I had ended up in Birmingham originally in September 1970.

Potatoes at Birmingham
It was at Birmingham that I first became involved with potatoes, a crop I researched for the next 20 years, completing my PhD (as did many others) under the supervision of Professor Jack Hawkes, a world-renowned expert on the genetic resources and taxonomy of the various cultivated potatoes and related wild species from the Americas. Jack began his potato career in 1939, joining Empire Potato Collecting Expedition to South America, led by Edward Balls. Jack recounted his memories of that expedition in Hunting the Wild Potato in the South American Andes, published in 2003.

The origins of the Commonwealth Potato Collection
Returning to Cambridge, just as the Second World War broke out, Jack completed his PhD under the renowned potato breeder Sir Redcliffe Salaman, who had established the Potato Virus Research Institute, where the Empire Potato Collection was set up, and after its transfer to the John Innes Centre in Hertfordshire, it became the Commonwealth Potato Collection (CPC) under the management of institute director Kenneth S Dodds (who published several keys papers on the genetics of potatoes).

Bolivian botanist Prof Martin Cardenas (left) and Kenneth Dodds (right). Jack Hawkes named the diploid potato Solanum cardenasii after his good friend Martin Cardenas. It is now regarded simply as a form of the cultivated species S. phureja.

Hawkes’ taxonomic studies led to revisions of the tuber-bearing Solanums, first in 1963 and in a later book published in 1990 almost a decade after he had retired. You can see my battered copy of the 1963 publication below.

Dalton Glendinning

The CPC was transferred to the Scottish Plant Breeding Station (SPBS) at Pentlandfield just south of Edinburgh in the 1960s under the direction of Professor Norman Simmonds (who examined my MSc thesis). In the early 1970s the CPC was managed by Dalton Glendinning, and between November 1972 and July 1973 my wife Steph was a research assistant with the CPC at Pentlandfield. When the SPBS merged with the Scottish Horticultural Research Institute in 1981 to form the Scottish Crops Research Institute (SCRI) the CPC moved to Invergowrie, just west of Dundee on Tayside. The CPC is still held at Invergowrie, but now under the auspices of the James Hutton Institute following the merger in 2011 of SCRI with Aberdeen’s Macaulay Land Use Research Institute.

Today, the CPC is one of the most important and active genetic resources collections in the UK. In importance, it stands alongside the United States Potato Genebank at Sturgeon Bay in Wisconsin, and the International Potato Center (CIP) in Peru, where I worked for more than eight years from January 1973.

Hawkes continued in retirement to visit the CPC (and Sturgeon Bay) to lend his expertise for the identification of wild potato species. His 1990 revision is the taxonomy still used at the CPC.

So what has this got to do with the EU?
For more than a decade after the UK joined the EU (EEC as it was then in 1973) until that late 1980s, that corner of Birmingham was effectively outside the EU with regard to some plant quarantine regulations. In order to continue studying potatoes from living plants, Jack Hawkes was given permission by the Ministry of Agriculture, Fisheries and Food (MAFF, now DEFRA) to import potatoes—as botanical or true seeds (TPS)—from South America, without them passing through a centralised quarantine facility in the UK. However, the plants had to be raised in a specially-designated greenhouse, with limited personnel access, and subject to unannounced inspections. In granting permission to grow these potatoes in Birmingham, in the heart of a major industrial conurbation, MAFF officials deemed the risk very slight indeed that any nasty diseases (mainly viruses) that potato seeds might harbour would escape into the environment, and contaminate commercial potato fields.

Jack retired in 1982, and I took up the potato research baton, so to speak, having been appointed lecturer in the Department of Plant Biology at Birmingham after leaving CIP in April 1981. One of my research projects, funded quite handsomely—by 1980s standards—by the Overseas Development Administration (now the Department for International Development, DFID) in 1984, investigated the potential of growing potatoes from TPS developed through single seed descent in diploid potatoes (that have 24 chromosomes compared with the 48 of the commercial varieties we buy in the supermarket). To cut a long story short, we were not able to establish this project at Winterbourne, even though there was space. That was because of the quarantine restrictions related to the wild species collections were held and were growing on a regular basis. So we reached an agreement with the Plant Breeding Institute (PBI) at Trumpington, Cambridge to set up the project there, building a very fine glasshouse for our work.

Then Margaret Thatcher’s government intervened! In 1987, the PBI was sold to Unilever plc, although the basic research on cytogenetics, molecular genetics, and plant pathology were not privatised, but transferred to the John Innes Centre in Norwich. Consequently our TPS project had to vacate the Cambridge site. But to where could it go, as ODA had agreed a second three-year phase? The only solution was to bring it back to Birmingham, but that meant divesting ourselves of the Hawkes collection. And that is what we did. However, we didn’t just put the seed packets in the incinerator. I contacted the folks at the CPC and asked them if they would accept the Hawkes collection. Which is exactly what happened, and this valuable germplasm found a worthy home in Scotland.

In any case, I had not been able to secure any research funds to work with the Hawkes collection, although I did supervise some MSc dissertations looking at resistance to potato cyst nematode in Bolivian wild species. And Jack and I published an important paper together on the taxonomy and evolution of potatoes based on our biosystematics research.

A dynamic germplasm collection
It really is gratifying to see a collection like the CPC being actively worked on by geneticists and breeders. Especially as I do have sort of a connection with the collection. It currently comprises about 1500 accessions of 80 wild and cultivated species.

Sources of resistance to potato cyst nematode in wild potatoes, particularly Solanum vernei from Argentina, have been transferred into commercial varieties and made a major impact in potato agriculture in this country.

Safeguarded at Svalbard
Just a couple of weeks ago, seed samples of the CPC were sent to the Svalbard Global Seed Vault (SGSV) for long-term conservation. CPC manager Gaynor McKenzie (in red) and CPC staff Jane Robertson made the long trek north to carry the precious potato seeds to the vault.

Potato reproduces vegetatively through tubers, but also sexually and produces berries like small tomatoes – although they always remain green and are very bitter, non-edible.

We rarely see berries after flowering on potatoes in this country. But they are commonly formed on wild potatoes and the varieties cultivated by farmers throughout the Andes. Just to give an indication of just how prolific they are let me recount a small piece of research that one of my former colleagues carried out at CIP in the 1970s. Noting that many cultivated varieties produced an abundance of berries, he was interested to know if tuber yields could be increased if flowers were removed from potato plants before they formed berries. Using the Peruvian variety Renacimiento (which means rebirth) he showed that yields did indeed increase in plots where the flowers were removed. In contrast, potatoes that developed berries produced the equivalent of 20 tons of berries per hectare! Some fertility. And we can take advantage of that fertility to breed new varieties by transferring genes between different strains, but also storing them at low temperature for long-term conservation in genebanks like Svalbard. It’s not possible to store tubers at low temperature.

Here are a few more photos from the deposit of the CPC in the SGSV.

I am grateful to the James Hutton Institute for permission to use these photos in my blog, and many of the other potato photographs displayed in this post.

 

Plant Genetic Resources: Our challenges, our food, our future

phillips-jade

Jade Phillips

That was the title of a one day meeting on plant genetic resources organized by doctoral students, led by Jade Phillips, in the School of Biosciences at The University of Birmingham last Thursday, 2 June. And I was honoured to be invited to present a short talk at the meeting.

Now, as regular readers of my blog will know, I began my career in plant genetic resources conservation and use at Birmingham in September 1970, when I joined the one year MSc course on genetic conservation, under the direction of Professor Jack Hawkes. The course had been launched in 1969, and 47 years later there is still a significant genetic resources presence in the School, even though the taught course is no longer offered (and hasn’t accepted students for a few years). Staff have come and gone – me included, but that was 25 years ago less one month, and the only staff member offering research places in genetic resources conservation is Dr Nigel Maxted. He was appointed to a lectureship at Birmingham (from Southampton, where I had been an undergraduate) when I upped sticks and moved to the International Rice Research Institute (IRRI) in the Philippines in 1991.

Potential for genetic diversity conservation – the ‘Fifth Dimension’ – within wider biodiversity protection

I guess there were about 25-30 participants in the meeting, mainly young scientists just starting their careers in plant genetic resources, but with a few external visitors (apart from speakers) from the Millennium Seed Bank at Kew-Wakehurst Place, the James Hutton Institute near Dundee, and IBERS at Aberystwyth.

The meeting grew out of an invitation to Åsmund Asdal from the Nordic Genetic Resources Center (NordGen) to present a School of Biosciences Thursday seminar. So the audience for his talk was much bigger.

asmund

Åsmund is Coordinator of Operation and Management for the Svalbard Global Seed Vault, and he gave a fascinating talk about the origins and development of this important global conservation facility, way above the Arctic Circle. Today the Vault is home to duplicate samples of germplasm from more than 60 depositor genebanks or institutes (including the international collections held in the CGIAR genebank collections, like that at IRRI.

Nigel Maxted’s research group has focused on the in situ conservation and use of crop wild relatives (CWR), although they are also looking at landrace varieties as well. Several of the papers described research linked to the CWR Project, funded by the Government of Norway through the Crop Trust and Kew. Postdocs and doctoral students are looking at the distributions of crop wild relatives, and using GIS and other sophisticated approaches that were beyond my comprehension, to determine not only where there are gaps in distributions, lack of germplasm in genebank collections, but also where possible priority conservation sites could be established. And all this under the threat of climate change. The various PowerPoint presentations demonstrate these approaches—which all rely on vast data sets—much better than I can describe them. So I encourage you to dip into the slide shows and see what this talented group of scientists has been up to.

Neil Munro from Garden Organic described his organization’s approach to rescue and multiply old varieties of vegetables that can be shared among enthusiasts.

n_munro

Seeds cannot be sold because they are not on any official list of seed varieties. What is interesting is that one variety of scarlet runner bean has become so popular among gardeners that a commercial seed company (Thompson & Morgan if I remember what he said) has now taken  this variety and selling it commercially.

julian

Julian Hosking from Natural England gave some interesting insights into how his organization was looking to combine the conservation of genetic diversity—his ‘Fifth Dimension’—with conservation of natural habitats in the UK, and especially the conservation of crop wild relatives of which there is a surprisingly high number in the British flora (such as brassicas, carrot, and onions, for example).

So, what about myself? When I was asked to contribute a paper I had to think hard and long about a suitable topic. I’ve always been passionate about the use of plant genetic diversity to increase food security. I decided therefore to talk about the value of genebank collections, how that value might be measured, and I provided examples of how germplasm had been used to increase the productivity of both potatoes and rice.

Nicolay Vavilov is a hero of mine

Although all the speakers developed their own talks quite independently, a number of common themes emerged several times. At one point in my talk I had focused on the genepool concept of Harlan and de Wet to illustrate the biological value (easy to use versus difficult to use) of germplasm in crop breeding.

Jackson FINAL - Valuing Genebank Collections

In the CWR Project research several speakers showed how the genepool concept could be used to set priorities for conservation.

Finally, there was one interesting aspect to the meeting—from my perspective at least. I had seen the titles of all the other papers as I was preparing my talk, and I knew several speakers would be talking about future prospects, especially under a changing climate. I decided to spend a few minutes looking back to the beginning of the genetic conservation movement in which Jack Hawkes was one of the pioneers. What I correctly guessed was that most of my audience had not even been born when I started out on my genetic conservation career, and probably knew very little about how the genetic conservation movement had started, who was involved, and what an important role The University of Birmingham had played. From the feedback I received, it seems that quite a few of the participants were rather fascinated by this aspect of my talk.

Through hard work, great things are achieved

BirminghamUniversityCrestPer Ardua Ad Alta

That’s the motto of The University of Birmingham, and ‘these sentiments sum up the spirit of Birmingham and illustrate the attitude of the people who have shaped both the city and the University.’

Almost 50 years ago, I had no inkling that I would have more than half a lifetime’s association with this university. Receiving its royal charter in 1900 (although the university was a successor to several institutions founded in the 19th century as early as 1828), Birmingham is the archetypal ‘redbrick university‘, located on its own campus in Edgbaston, about 3 miles southwest of Birmingham city center.


First encounter in 1967

My first visit to the university was in May or June 1967—to sit an exam. Biology was one of the four subjects (with Geography, English Literature, and General Studies) I was studying for my Joint Matriculation Board Advanced Level high school certificate (essentially the university entrance requirement) here in the UK. We were only four or five biology students at my high school, St Joseph’s College in Trent Vale, Stoke-on-Trent (motto: Fideliter et Fortiter).

Now, I don’t remember (maybe I never knew) whether we were too few in number to sit our biology practical exam at the school, or all students everywhere had to attend an examination venue, but we set off by train from Stoke to Birmingham, and ended up at the School of Biological Sciences building. It was a new building then, and the (federal) School had only recently been formed from the four departments of Botany, Zoology & Comparative Physiology, Genetics, and Microbiology.

Just before 2 pm, the five of us—and about 100 other students—trooped into the main laboratory (that I subsequently came to know as the First Year Lab) on the second floor. Little did I know that just over three years later I’d be joining the Department of Botany as a graduate student, nor that 14 years later in 1981 I would join the faculty as Lecturer in Plant Biology. Nothing could have been further from my mind as I settled down to tackle a dissection of the vascular system of a rat, and the morphology of a gorse flower, among other tasks to attempt.

Birmingham was not on the list of universities to which I had applied in December 1966. I’d chosen King’s College, London (geography), Aberystwyth (zoology and geography), Southampton (botany and geography), York (biology), Queen Mary College, London (general biological sciences), and Newcastle (botany and geography). In the end, I chose Southampton, and spent three very happy if not entirely fruitful years there.

Entering the postgraduate world

Jack Hawkes

The next time I visited Birmingham was in February 1970. I had applied to join the recently-founded postgraduate MSc Course on Conservation and Utilization of Plant Genetic Resources. I was interviewed by Course Director and Head of the Department of Botany, Professor JG Hawkes and Senior Lecturer and plant ecologist, Dr Denis Wilkins.

Despite the grilling from both of  them, I must have made an impression because I was offered a place for the following September. The only problem: no support grant. Although Hawkes had applied for recognition by one of the research councils to provide postgraduate studentships, nothing had materialized when I applied (although he was successful the following year, and for many years afterwards providing studentships to British students). So, after graduation from Southampton in July 1970 I was on tenterhooks all summer as I tried to sort out a financial solution to attend the course. Finally, around mid-August, I had a phone call from Hawkes telling me that the university would provide a small support grant. It was only £380 for the whole year, to cover all my living expenses including rent. That’s the equivalent of about £5600 today. The university would pay my fees.

All set then. I found very comfortable bed-sit accommodation a couple of miles from the university, and turned up at the department in early September to begin my course, joining four other students (from Nigeria, Pakistan, Turkey and Venezuela). It was during this one year course that I really learned how to study, and apart from my weekly Morris dancing night, I had few other distractions. It was study, study, study: and it paid off. The rest is history. I graduated in September 1971, by which time I’d been offered a one-year position at the newly-founded International Potato CenterCIP logo (CIP) in Lima, Peru, and I was all set for a career (I hoped) in the world of genetic resources and conservation. As it turned out, my travel to South America was delayed by more than a year during which time I registered for and commenced a PhD study on potatoes, finally landing in Lima in January 1973 and beginning a career in international agricultural research that lasted, on and off, until my retirement in 2010. I carried out most of my PhD research in Peru, and submitted my thesis in October 1975.

Then I returned to Lima, spending another five years with CIP in Costa Rica carrying out research on bacterial diseases of potatoes among other things.

I should add that during the academic year 1971-72, a young woman, Stephanie Tribble, joined the MSc course. A few months later we became an ‘item’.

Steph’s MSc graduation at the University of Birmingham in December 1972, just weeks before I flew to South America and join the International Potato Center in Lima, Peru.

After graduation, she joined the Scottish Plant Breeding Station just south of Edinburgh, but joined me in Lima in July 1973. We married there in October, and she also had a position with CIP for the years we remained in Lima.

A faculty position
On 1 April 1981 I joined the University of Birmingham as a lecturer in the Department of Plant Biology.

Richard Sawyer

By mid-1980, after almost five years in Costa Rica, I felt that I had achieved as much as I could there, and asked my Director General in Lima, Dr Richard Sawyer, for a transfer to a new position. In November, we moved back to Lima, and I was expecting to be posted either to Brazil or possibly to the Philippines. In the meantime, I had been alerted to a recently-established lectureship in the Department of Plant Biology (formerly Botany) at Birmingham, and had been encouraged to apply¹. With encouragement from Richard Sawyer², and having been invited for interview, I made the trek back to the UK from Lima towards the end of January 1981. The interview process then was very different from what might be expected nowadays. No departmental seminar. Just a grilling from a panel chaired by the late Professor John Jinks, FRS, Dean of the Faculty of Science and head of the Department of Genetics. There were three staff from Plant Biology (Hawkes, Dennis Wilkins, and Brian Ford-Lloyd), and the head of the Department of Biochemistry and Deputy Dean, Professor Derek Walker.

We were three candidates. Each interview lasted about 45 minutes, and we all had to wait outside the interview room to learn who would be selected. I was interviewed last. Joining the other two candidates afterwards, we sat side-by-side, hardly exchanging a word between us, nervously waiting for one of us to be called back in to meet the panel. I was the lucky one. I was offered the position, accepted immediately, and a couple of days later flew back to Lima to break the news and make plans to start a new life with Steph and our daughter Hannah (then almost three) in Birmingham.

Over the 10 years I spent at Birmingham I never had the worry (or challenge) of teaching any First Year Course – thank goodness. But I did contribute a small module on agricultural systems to the Second Year common course (and became the Second Year Chair in the School of Biological Sciences), as well as sharing teaching of flowering plant taxonomy to plant biology stream students mtj-and-bfl-book-launchin the Second Year. With my colleague Brian Ford-Lloyd (with whom I’ve published three books on genetic resources) I developed a Third Year module on genetic resources that seems to have been well-received (from some subsequent feedback I’ve received). I also contributed to a plant pathology module for Third Year students. But the bulk of my teaching was to MSc students on the graduate course on Conservation and Utilization of Plant Genetic Resources – the very course I’d attended a decade earlier. My main focus was crop evolution, germplasm collecting, and agricultural systems, among others. And of course there was supervision of PhD and MSc student research projects.

One of the responsibilities I enjoyed was tutoring undergraduate students, and always had an open door if they needed to see me. It quite shocked me in the late 1990s when my elder daughter, then a student at Swansea University, told me that her tutors had very limited and defined access hours for students. Of course you can’t be on call all day, every day, but you have to be there if a student really need to see you. And my tutees knew that if my office door was open (as it mostly was) they were free to come in and see me.

Once the four departments of the School of Biological Sciences merged into a single department in 1988, I aligned myself with and joined the Plant Genetics Group, and found a better role for myself. I also joined and became Deputy Chair of a cross-disciplinary group called Environmental Research Management (ERM) whose aim was to promote the strength of environment-related research across the university. Through ERM I became acquainted with Professor Martin Parry, and together with Brian Ford-Lloyd we published a book on genetic resources and climate change in 1990, and another in 2014 after we had retired.

Moving on
Even though the prospect of promotion to Senior Lecturer was quite good (by 1989 I’d actually moved on to the Senior Lecturer pay scale), I was becoming somewhat disillusioned with university life by that time. Margaret Thatcher and her government had consistently assaulted the higher education sector, and in any case I couldn’t see things getting any better for some years to come. In this I was unfortunately proved correct. In September 1990 a circular dropped into my post, advertising a new position at the International Rice Research Institute (IRRI) in the Philippines. This was for a germplasm specialist and first head of the Genetic Resources Center. So I applied, was interviewed in January 1991, and accepted the position with a view to joining the institute from 1 July. They actually wanted me to start on 1 April. But as I explained—and IRRI Management accepted—I had teaching and examination commitments to fulfill at the university. In February I began to teach my third year module on genetic resources for the last time, and set the exams for all students to take in May and June. Once the marking and assessments had been completed, I was free to leave.

Friday 28 June was my last day, ending with a small farewell party in the School. I flew out to the Philippines on Sunday 30 June. And, as they say, the rest is history. I never looked back. But now, retirement is sweet, as are my memories.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
¹ Jack Hawkes was due to retire in September 1982 and, recognizing that his departure would leave a big hole in the MSc teaching, the university approved the recruitment of a lecturer in plant genetic resources (with a focus on crop evolution, flowering plant taxonomy, and the like) essentially covering those areas where Jack had contributed.
² Dick Sawyer told me that applying for the Birmingham position was the right thing to do at that stage of my career. However, the day before I traveled to the UK he called me to his office to wish me well, and to let me know whichever way the interview went, he would have a new five-year contract waiting on his desk for me on my return. From my point of view (and I hope CIP’s) it was a win-win situation. Thus I left for the interview at Birmingham full of confidence.

 

Completing a PhD – was it worth the effort?

A topical story in the Lima press
Overnight, there was an interesting and topical post (as far as I’m concerned) on the Facebook page of one of my ‘friends’—the son of one of my graduate students when I was a faculty member at The University of Birmingham in the 1980s. He hails from Peru. Carlos Arbizu Jr. is studying for his PhD at the University of Wisconsin-Madison and, as far as I can determine, he’s working on carrot genetics under the supervision of my friend and former potato scientist David Spooner.

Carlos had posted a link to an article published on the website of the Lima-based Newspaper Perú21: ¿Por qué estudiar un doctorado?  (Why study for a PhD?). To which Carlos had added the byline: PhD = Permanent Head Damage.

Maybe he’s going through a difficult patch right now. I’ve seen from several of his posts that he’s immersed in some pretty ‘heavy’ molecular genetic analysis. It’s beyond my comprehension.

But all PhD students go through peaks and troughs. I know I did. Some days nothing can go wrong, progress is swift. The world is your oyster, and there really is a light at the end of the tunnel. On other days, you just wish the earth would open up and swallow you.

And for many PhD students, the most trying time often comes when they begin to draft their thesis and eventually prepare to defend it. Unfortunately many science graduates have received very little formal training in how to write clear and concise prose. Writing just doesn’t come naturally. So what should be one of the most important aspects of completing a PhD can become a long and tedious chore. And before submission regulations were tightened up at UK universities, some students could take a couple of years or more to write up and submit their thesis for examination.

40 years ago today
Well, this Perú21 article was published yesterday. And today, 23 October (if memory serves me right) is exactly 40 years since I defended my PhD thesis: The Evolutionary Significance of the Triploid Cultivated Potato, Solanum x chaucha Juz. et Buk. I was almost 27 (old by UK standards, average or maybe young compared to many US graduate students), and had been working on my degree for four years. I’d completed a one-year MSc degree in genetic resources at Birmingham in September 1971 (having graduated from the University of Southampton with a BSc in botany and geography in July 1970), and then been offered the opportunity to work in Peru for a year at the newly-established International Potato Center (CIP). Well, for various reasons, and to cut a long story short, That opportunity didn’t materialize in September 1971 so my head of department, Professor Jack Hawkes (who went on to supervise my PhD) persuaded the Overseas Development Administration (now Department for International Development, DfID) to cough up some support until the funding for my position at CIP was guaranteed. Thus I began my study in Birmingham, and finally moved to Lima in January 1973, working as an Associate Taxonomist and conducting research that went towards my PhD thesis. And since I was employed and having a regular income, I took another three years to complete all the experimental work I had planned. In any case, when I joined CIP in 1973 the institute was still establishing and developing its own infrastructure. That was also one of the exciting aspects to my work. It was a real opportunity to build up and curate a large collection of Andean potato varieties and wild species, and study them in their native environment.

Learning from my supervisor, Professor Jack Hawkes, during one of his visits to Peru while I was carrying out my study.

MTJ in CIP

With CIP taxonomist, Professor Carlos Ochoa, a renowned Peruvian expert on potatoes and their wild relatives.

I was looking at the relationship between potato varieties with different chromosome numbers, so-called diploids and tetraploids, with 24 and 48 chromosomes respectively. If you can cross these two types you expect to produce some with an intermediate chromosome number. So, 48 x 24 = 36, the triploids. For the first years at CIP we didn’t have any glasshouses where we could work. Instead we had rather rustic polytunnels right in the field next to the germplasm collection, where I would make all those pollinations using the so-called cut-stem technique.

Experimental data from other parts of the world had shown that triploids were formed only rarely in such crosses. Yet triploid varieties were quite common and highly prized by potato farmers in the Andes. I was trying to determine if the crossability relationships of these native potatoes might be different in their indigenous environment. So I went on to make hundreds of crosses (and thousands of pollinations), as well as study indigenous farming systems in the south of Peru. This next gallery show some of the triploids potatoes grown by farmers. One of the most prized was the variety Huayro, and there were two forms, one round and the other elongated (and quite large). Both had red skins and yellow flesh.

Back to Birmingham
In May 1975, Steph and I headed back to the UK. But not directly. On the assumption that I would successfully defend my PhD thesis, CIP’s Director General had offered me a new position in the Outreach Department, and with the possibility of moving to Central America. So we headed for Costa Rica (where I’d eventually move to in April 1976) to see the lie of the land, so to speak. And from there we went on to Mexico for a few days to visit our old friends, and former CIP colleagues, John and Marion Vessey who had moved to maize and wheat center, CIMMYT, near Mexico City. From Mexico we headed to New York (first flight on a wide-bodied jet, an Eastern Airlines L-1011 Tristar) for a connection with British Airways to Manchester where my parents met us. We spent a further week looking for somewhere to live in Birmingham, and were fortunate to find an apartment very convenient to the university and only a few minutes walk from the Department of Botany (as it was then) Winterbourne Gardens where I had been assigned some lab space and a desk.

A nightmare waiting to happen
Now remember, there were no PCs or laptops, cloud computing, USB sticks or floppy disks in 1975. All my thesis data was available in hard copy only, and I carried a briefcase with four years of work with me from Lima to the UK on that journey I just related. The briefcase was hardly ever out of my sight! In those days it was not unknown for a graduate student to have lost a briefcase on a journey containing a complete draft of a thesis. No backup!

Getting into a routine
Once settled in Birmingham, I planned out my work for the coming months, with a deadline of 1 October. That was the final day of submission if I wanted to have my thesis examines and (if approved) have the degree awarded at the next congregation or commencement in early December that same year. But by the beginning of June I had not even begun to write, never mind complete the last minute field experiment I had planned (checking the ploidy of a set of hybrids produced earlier in the year) or create the figures I would include. Again, there was no digital technology available. I had to hand draw all my maps and other figures (my geography training in cartography at Southampton finally came in useful). While the department’s chief technician actually photographed all of these, I had to print all my own photographs (again, the experience I’d gained from my father, a professional photographer all his life, came in handy).

Working to a regular schedule every day, from around 7:30 am until 5 pm with a break for lunch, and spending another couple of hours after dinner, I soon began to make progress, although I didn’t actually start putting pen to paper until the beginning of July. It took me only six weeks to draft my thesis. Once I’d completed a chapter I’d hand it over to Jack Hawkes for review and revision. And to give him credit, he usually handed me back my draft with his comments within a couple of days only (and this was an approach I adopted with all my graduate students during the 1980s).

So, by mid-August or so I had a completed text, I’d checked the chromosome numbers of the hundred or so plants in the field, and set about the figures. I found someone who would type my thesis, but at the last moment he had to use a manual typewriter since the electric one he’d wanted to rent was no longer available. In 1975 The University of Birmingham changed the thesis submission regulations and it was no longer necessary to submit a thesis fully bound in a hard cover. I was able to submit in temporary binding, and this in fact saved perhaps three weeks from my tight schedule. I hit the 1 October deadline with about twenty minutes to spare just before 5 pm.

Thesis defence
I was quite surprised when my external examiner planned the defence of my thesis just three weeks later. All went to plan. In those days, the exam consisted of the graduate student, the external examiner and an internal examiner (usually the thesis supervisor). Today things might have changed, and even when I worked at Birmingham in the 80s the supervisor was no longer permitted to act as the internal examiner. I believe there may now also be a third panel member, to see fair play.

From the outset it was apparent that my thesis would pass muster, since the external examiner told me that he’d enjoyed reading the thesis. But we then went on to have a thorough discussion over the next three hours about many of the details, and the implications for potato genetic conservation and breeding. Phew!

And in early December, the 12th actually, I was able to celebrate with others from the department as we were awarded our degrees at the mid-year congregation.

Was it worth it?
So let me come back to the question I posed in the title of this post. Was it worth it? Unequivocally Yes! Would I want to do it again? No!

Actually completing a PhD is probably the most selfish piece of research that a scientist will ever get to do. There’s one aim: complete a thesis and have the doctorate awarded. PhD research does not have to be ground-breaking at all. In fact much of it is pretty mundane, and that’s one of the down sides when things are not going so well. For Birmingham at least, the PhD regulations stated that the thesis had to represent a piece of original research, completed under supervision. And it’s the ‘under supervision’ that is critical. A PhD student is still maturing, so to speak. The work is guided by a mentor. Of course there can be breakthroughs that lead to the most prestigious prizes. I believe that Sir Paul Nurse’s PhD research set him off on the path that eventually led to his Nobel prize.

I have encouraged others to research for a PhD, and I hope I was able to give them the support and advice that my supervisors gave me. In that respect my PhD was a positive experience. It’s not always the case, and when student-supervisor relationships break down, every one suffers. It does not necessarily have to take many, many months (or years even) to write a thesis. It takes self-discipline but also support from the supervisor.

Without a PhD I would not have enjoyed the career in international agricultural research and academia that I did. My PhD was like a ‘union card’. It enabled me to seek opportunities that would probably have been closed without a PhD. But I also acknowledge that I was lucky. I moved into a field—genetic resources—that was just expanding, as were the international centers of the CGIAR. And I had mentors who were prepared to back me.

Forty years on I can look back to those days in 1975 with a fair degree of nostalgia. And then reflect on the benefits that accrued from that intense but disciplined period in the summer of 1975 (when there was a heat wave, and Arthur Ashe won the men’s title at Wimbledon), and which allow me now to enjoy the retirement I started five years ago.

Both of our daughters, Hannah and Philippa, went on to complete a PhD (in 2006 and 2010, respectively) in their chosen field: psychology! So I can’t have passed on so many negative vibes about graduate study, although their choice of psychology does make a profound statement, perhaps.

Peer-reviewed papers
Incidentally, I finally got around to publishing three papers from my thesis. When I returned to CIP just before New Year 1976, I moved into a new role and responsibilities. And even though I eventually found time to draft manuscripts, these took some time to appear in print after peer review, revision and acceptance. One of the papers—on the field work at Cuyo Cuyo—was originally submitted to the journal Economic Botany. And there it languished for over two years. I received an invitation from the editor of Euphytica to submit a paper on the same topic, so I withdrew my manuscript from Economic Botany. About that same time I received a letter from that journal’s interim editor in chief that manuscripts had been discovered unpublished up to 20 years after they had been submitted, and what did I want to happen to mine. It was published in Euphytica in 1980.

A lifetime’s work . . .

I published my first scientific paper in 1972. It described a new technique to make root tip squashes to count chromosomes, and it was published in the August 1972 volume of the Journal of Microscopy. It came out of the work I did for my MSc dissertation on lentils and their origin.

Then in January 1973 I entered the world of work, and for the next 37 years until my retirement in April 2010, I worked as a research scientist or research manager at just three organizations (although I actually held five different positions) at: the International Potato Center (CIP) in Peru (1973-1981); The University of Birmingham (1981-1991); and the International Rice Research Institute (IRRI) in the Philippines (1991-2010).

The focus of my research was primarily the conservation and use of plant genetic resources, specifically of potatoes, grain legumes, and rice, with biosystematics and genetic diversity, as well as different approaches to germplasm conservation, being particular themes. But I also studied potato diseases and agronomy.

So as much for my own interest and anyone else who might like to review my scientific contributions, this blog post relates specifically to my refereed papers, books, chapters, and other miscellaneous publications that I have written over the decades.

Science is a collaborative endeavor, and I have been extremely fortunate to have had the opportunity of working with some outstanding colleagues from different organizations around the world, as well as supervising the research of great graduate students at Birmingham for their PhD degrees, or staff at the Genetic Resources Center at IRRI. But having taken on a senior management role at IRRI in 2001 there was obviously less opportunity therefater to engage in scientific publication, apart from several legacy studies from my active research years.

PAPERS IN REFEREED JOURNALS

Biosystematics & germplasm diversity
I trained as a biosystematist looking at the species relationships of lentils and potatoes. So when I moved to IRRI in 1991, I decided that we needed to understand better the germplasm collection (now more than 117,000 seed accessions of cultivated and wild rices) in terms of species range and relationships. Over the next 10 years we invested in a significant effort to study the AA genome species most closely related to cultivated rice, Oryza sativa. We also reported some of the first applications of molecular markers to study a germplasm collection, and one of the first—if not the first—studies in association genetics, in a collaboration with The University of Birmingham and the John Innes Centre, Norwich.

Germplasm conservation
The 14 papers in this section focus primarily on studies we carried out at IRRI to enhance the conservation of rice seeds. It’s interesting to note that new research on seed drying just published by seed physiologist Fiona Hay and colleagues at IRRI has thrown some doubt on the seed drying measures we introduced in the mid-1990s. But there is much more to learn, and after all, that’s the way of science.

“Education isn’t what you learn, it’s what you do with what you learn.” Anon.

degreeThere’s been quite a bit in the news again recently about the value of a university education, after George Osbourne, the UK’s Chancellor of the Exchequer, announced the scrapping of maintenance grants from the 2016/17 academic year. From that date, grants will be replaced by loans, adding yet further to the financial loan burden that university students are already facing to pay their tuition fees through loans. These financial challenges are making some (or is it many?) prospective students question whether they really do want or need a university education. Add to that the pressure on prospective students to study a subject that ‘should contribute’ more effectively to society and the economy, it’s no wonder that students are beginning to have second thoughts about going to university.

Also, with the publication of this year’s university exam results, the issue of grade creep is once again on the political agenda, since more than 50% of all students have graduated with a so-called ‘good’ degree. In the UK, this is a First or Upper Second (2:1) Class degree.

So why have these issues now attracted my attention?

Life on the south coast
Early July 1970. Forty-five years! It’s hard to believe. Yes, it’s forty-five years since I graduated from the University of Southampton with a BSc degree (not a very good one, I’m afraid) in Environmental Botany and Geography. There again, no-one in my year gained a First in botany, only a couple in geography. They didn’t hand out many top degrees in those days. More than 70% of students today are awarded a First or Upper Second. What is interesting from my point of view is during my high school years, going to university was not a foregone conclusion, or even an expectation for that matter. However, a university education was something that my post-war generation did begin aspire to. I was only the second person in my family to attend university.

55 Ed & Mike

Graduation Day, July 1970 at the University of Southampton, with my Mum and Dad, Lilian and Fred Jackson. Was I ever that young looking?

Now, although I didn’t exactly excel academically at Southampton, I wouldn’t have traded those three undergraduate years for anything. Some of the best years I have ever spent. Ah, the enthusiasm of youth. Did I ever have second thoughts? Never. I was extremely fortunate that my parents were very supportive, even though it must have been hard financially for them at times. My elder brother Ed had (in 1967) just graduated from the London School of Economics (with a First in geography) when I started at Southampton. So my parents were faced with another three years of support, even though my tuition fees were paid by the state, and I did receive a maintenance grant which Mum and Dad had to top up.

I guess I was lucky that Southampton took me in the first place, and didn’t throw me out after my first year. I never was very good at taking exams, well not in those school and undergraduate years. I only found my métier once I’d moved on to graduate school in 1971.

I went for an admissions interview at Southampton in early 1967 and immediately knew that this was where I wanted to study at, if they offered me a place. So once I received the results from my high school A-level exams (in biology, geography, and English literature, but not quite what I’d hoped for, grades-wise) I was on tenterhooks for a couple of weeks waiting for a response from the university. I was earning some cash, working as a lorry (truck) driver’s mate for a company based in Leek called Adams Butter. We delivered processed butter to retail outlets all over the UK, often being away from home for several nights at a stretch. Then once we delivered our load of about 25 tons of butter, we would head to the nearest port to pick up another 25 tons of Australian or New Zealand ‘raw’ butter, in large 56 lb frozen packs. I soon got fit throwing those boxes around.

Anyway, to cut a long story short, I arrived back at the depot after a long day on the road, and my father had kindly left a brief message with the dispatcher on duty: “Southampton wants you!” Obviously elated, I began to make plans to start my university life in October. The rest is history.

Back to the Midlands
Having graduated, I still didn’t know what the next stage of my life held. I’d applied to The University of Birmingham for a place on its newly-established MSc course Conservation and Utilization of Plant Genetic Resources in the Department of Botany. In February 1970 I’d been interviewed by course director Professor Jack Hawkes, and was offered a place, but with no guarantee of any financial support. It wasn’t until mid-August that I received a phone call confirming that he had been able to secure a small maintenance grant (just over £6 a week for the whole year, equivalent to about £80 a week today) and payment of my tuition fees. Undaunted at the prospect, I quickly accepted. And what a joy studying at Birmingham was. I certainly found an area of plant sciences that I could really immerse myself in, the staff were (on the whole) inspiring (particularly Trevor Williams with whom I completed my thesis), and I knew that I’d made the right choice.

But still there was no guarantee of gainful employment in my chosen field. That is until Jack Hawkes invited me to consider a one-year position in Peru. As things turned out, I did make it to Peru, registered for a PhD (which I completed in 1975), and made a career for myself in international agricultural research and academia. I received my degree from the Chancellor of the University, Sir Peter Scott, renowned ornithologist and conservationist, and son of ill-fated Antarctic explorer, Captain Scott at a graduation ceremony at the University of Birmingham on 12 December 1975.

Was it worth it?
When I decided to study botany at university I had no idea whether this would lead to a worthwhile career. Actually, it was not something I considered when applying. I just knew I wanted to study plants and geography, and then I’d see what life had in store for me afterwards, assuming I did actually graduate.

Steph studied botany at Swansea University (BSc 2:1), and we met at Birmingham when she studied for her MSc (also in genetic resources conservation) in 1971-72.

1972 002 Steph MSc

Steph’s MSc graduation in December 1972. This was about three weeks before I headed off to Peru. Steph joined me there in July 1973, and we were married in Lima in October that same year. We both had considerably longer hair then – and darker!

I think there was more expectation that our daughters, Hannah and Philippa, would go on to university, from our point of view and theirs. Indeed, having had the advantage of attending an international (and quite competitive) school in Manila, and studying for the International Baccalaureate diploma, university was the logical next step. And they both chose psychology (with an anthropology minor)—it wasn’t planned that way, that’s how it turned out.

Hannah originally started her university years at Swansea University in 1996, but after two years she transferred to one of the top liberal arts colleges in the USA: Macalester College in St Paul, and graduated BA summa cum laude in 2000 (left below, with the gold tassel). She then went on to the University of Minnesota to complete her PhD in industrial and organizational psychology in September 2006 (right below).

Philippa joined Durham University in 2000, and graduated in 2003 with her BSc (2:1) Honours degree (left below). After spending a year in Canada, she returned to the UK in 2004 and spent six months of more searching for a job. Eventually she secured a Research Assistantship in the Brain, Performance and Nutrition Research Centre at Northumbria University in Newcastle upon Tyne. After a couple of years she decided to register for a PhD and she was awarded her doctorate in December 2010 (right below).

So we’ve all benefited from having attended university, and have gone on to have successful careers. But I still believe it was the overall experience of university life as much as the academics that contributed those benefits. Unlike students today, we were fortunate not to have racked up significant debts while studying, and already Hannah and Philippa and their spouses are making plans for college education for their children—should they opt to follow that option.

I think the words of Cardinal John Henry Newman (1801-1890) are appropriate and as good today as when he wrote them in his essay ‘The Idea of a University’ in 1852: If then a practical end must be assigned to a University course, I say it is that of training good members of society… It is the education which gives a man a clear, conscious view of their own opinions and judgements, a truth in developing them, an eloquence in expressing them, and a force in urging them. It teaches him to see things as they are, to go right to the point, to disentangle a skein of thought to detect what is sophistical and to discard what is irrelevant.

I’m not sure that we do achieve those lofty ideals today as perhaps they aspired to in Newman’s day. There are just so many students moving through the system, the pressures to achieve are greater. While I was teaching at The University of Birmingham (for a decade in the 1980s) I became even more convinced that a university education is, in itself, worthwhile. This is often the first time that a young person leaves home, and has the opportunity to grow up away from the ever-watchful eyes of parents. Not everyone takes to university it must be said. But I think the majority who do make it to university would agree that, just like me, the three years they spend studying—and playing—are not three years wasted. It also makes it especially worrying that politicians are increasingly threatening the very existence and roles of universities, as is happening, for example, in a high profile way at the University of Wisconsin.

Don’t put all your eggs in one basket . . . or your seeds in a single genebank

On 20 May 2015, a long article was published in The Guardian about the Svalbard Global Seed Vault (SGSV), popularly—and rather unfortunately—known as the ‘Doomsday Vault’. I’ve recently been guilty of using that moniker simply because that’s how the vault has come to be known, rightly or wrongly, in the media.

Authored by US-based environment correspondent of The Guardian, Suzanne Goldenberg, the article had the headline grabbing title: The doomsday vault: the seeds that could save a post-apocalyptic world.

You get a flavor of what’s in store, however, from the very first paragraph. Goldenberg writes: ‘One Tuesday last winter, in the town nearest to the North Pole, Robert Bjerke turned up for work at his regular hour and looked at the computer monitor on his desk to discover, or so it seemed for a few horrible moments, that the future of human civilisation was in jeopardy.’

Turns out there was a relatively minor glitch in one of the supplementary cooling systems of this seed repository under the Arctic permafrost where millions of seeds of the world’s most important food staples and other species are being stored, duplicating the germplasm conservation efforts of the genebanks from which they were sent. Hardly the stuff of Apocalypse Now. So while making a favorable case for the need to store seeds in a genebank like the Svalbard vault, Goldenberg ends her introduction with this somewhat controversial statement: ‘Seed banks are vulnerable to near-misses and mishaps. That was the whole point of locating a disaster-proof back-up vault at Svalbard. But what if there was a bigger glitch – one that could not be fixed by borrowing a part from the local shop? There is now a growing body of opinion that the world’s faith, in Svalbard and the Crop Trust’s broader mission to create seed banks, is misplaced. [The emphasis in bold is mine.] Those who have worked with farmers in the field, especially in developing countries, which contain by far the greatest variety of plants, say that diversity cannot be boxed up and saved in a single container—no matter how secure it may be. Crops are always changing, pests and diseases are always adapting, and global warming will bring additional challenges that remain as yet unforeseen. In a perfect world, the solution would be as diverse and dynamic as plant life itself.’ 

I have several concerns about the article—and the many comments it elicited that stem, unfortunately, from lack of understanding on the one hand and ignorance and prejudice on the other.

  • Goldenberg gives the impression that it’s an either/or situation of ex situ conservation in a genebank versus in situ conservation in farmers’ fields or natural environments (in the case of crop wild relatives).
  • There is a perception apparently held by some that the development of the SGSV has been detrimental to the cause of in situ conservation of crop wild relatives.
  • Because there is no research or use of the germplasm stored in the SGSV, then it only has an ‘existence value’. Of course this does not take into account the research on and use of the same germplasm in the genebanks from which it was sent to Svalbard. Therefore Svalbard by its very nature is assumed to be very expensive.
  • The role of Svalbard as a back-up to other genebank efforts is not emphasized sufficiently. As many genebanks do not have adequate access to long-term conservation facilities, the SGSV is an important support at no cost directly to those genebanks as far as I am aware. However, Svalbard can never be a panacea. If seeds of poor quality (i.e less than optimum viability) are stored in the vault then they will deteriorate faster than good seeds. As the saying goes: ‘Junk in, junk out’.
  • The NGO perspective is interesting. It seems it’s hard for some of our NGO colleagues to accept that use of germplasm stored in genebanks actually does benefit farmers.Take for example the case of submergence tolerant rice, now being grown by farmers in Bangladesh and other countries on land where a consistent harvest was almost unheard of before. Or the cases where farmers have lost varieties due to natural disasters but have had them replaced because they were in a genebank. My own experience in the Cagayan valley in the northern Philippines highlights this very well after a major typhoon in the late 1990s devastated the rice agriculture of that area. See the section about on farm management of rice germplasm in this earlier post. They also still harbour a concern that seeds in genebanks are at the mercy of being expropriated by multinationals. In the comments, Monsanto was referred to many times, as was the issue of GMOs. I addressed this in the comment I contributed.

I added this comment that same day on The Guardian web site:
‘For a decade during the 1990s I managed one of the world’s largest and most important genebanks – the International Rice Genebank at the International Rice Research Institute (IRRI) in the Philippines. Large, because it holds over 116,000 samples of cultivated varieties and wild species of rice. And important, because rice is the most important food staple feeding half the world’s population several times daily.

The Svalbard Global Seed Vault (SGSV), the so-called ‘Doomsday Vault’ in Spitsbergen, holds on behalf of IRRI an almost complete duplicate set of samples (called ‘accessions’), in case something should happen to the genebank in Los Baños, south of Manila. I should add that for decades the USDA has also held a duplicate set in its genebank at Fort Collins in Colorado, under exactly the same ‘black box’ terms as the SGSV.

Germplasm is conserved so that it can be studied and used in plant breeding to enhance the productivity of the rice crop, to increase its resilience in the face of climate change, or to meet the challenge of new strains of diseases and pests. The application of molecular biology is unlocking the mysteries of this enormous genetic diversity, making it accessible for use in rice improvement much more efficiently than in past decades.

Many genebanks round the world and the collections they manage do not have access to long-term and safe storage facilities. This is where the SGSV plays an important role. Genebanks can be at risk from a whole range of natural threats (earthquakes, typhoons, volcanic eruptions, etc.) or man-made threats: conflicts, lack of resources, and inadequate management that can lead to fires, flooding, etc. Just take the example of the International Rice Genebank. The Philippines are subject to the natural threats mentioned, but the genebank was designed and built to withstand these. The example of the ICARDA genebank in Aleppo highlights the threat to these facilities from being located in a conflict zone.

To understand more about what it means to conserve a crop like rice please visit this post on my blog.  There is an enlightening 15 minute video there that I made about the genebank.

It is not a question of taking any set of seeds and putting them into cold storage. Only ‘good’ seeds will survive for any length of time under sub-zero conditions. Many studies have shown that if stored at -18C, seeds with initial high viability may be stored for decades even hundreds of years. The seeds of many plant species – including most of the world’s most important food crops like rice, wheat, maize and many others conform to this pattern. What I can state unequivocally is that the seeds from the genebanks of the world’s most important genebanks, managed like that of IRRI under the auspices of the Consultative Group on International Agricultural Research (CGIAR), have been routinely tested for viability and only the best sent to Svalbard.

The other aspect of Goldenberg’s otherwise excellent article are the concerns raised by a number of individuals whose ‘comments’ are quoted. I count both Phil Pardey and Nigel Maxted among my good friends, and it seems to me that their comments have been taken completely out of context. I have never heard them express such views in such a blunt manner. Their perspectives on conservation and use, and in situ vs. ex situ are much more nuanced as anyone will see for themselves from reading their many publications. The SEARICE representative I do not know, but I’ve had many contacts with her organization. It’s never a question of genebank or ex situ conservation versus on-farm or in situ conservation. They are complementary and mutually supportive approaches. Crop varieties will die out for a variety of reasons. If they can be stored in a genebank so much the better (not all plant species can be stored successfully as seeds, as was mentioned in Goldenberg’s article). The objection to genebanks on the grounds of permitting multinationals to monopolize these important genetic resources is a red herring and completely without foundation.

So the purpose of the SGSV is one of not ‘putting all your eggs in one basket’. Unfortunately the name ‘Doomsday Vault’ as used by Goldenberg has come to imply a post cataclysm world. It’s really much more straightforward than that. The existence of the SGSV is part of humanity’s genetic insurance policy, risk mitigation, and business continuity plan for a wise and forward-thinking society.’

Over the next couple of days others chipped in with first hand knowledge of the SGSV or genetic conservation issues in general.

Simon Jeppsonsiminjeppson is someone who has first-hand knowledge and experience of the SGSV, and he wrote: ‘I’m currently working as the project coordinator of the Svalbard Global Seed Vault on behalf of NordGen and I just wanted to add some of my reflections on this article some of the comments.

This article is an interesting read but a rather unbalanced one. The temperature increase that is described as putting the world heritage in jeopardy is a misconception. There has been a background study used as a worst case scenario during the planning stage of the Svalbard Global Seed Vault based on the seeds stored in the old abandoned mine shaft mentioned. These results were published in 2003 and even the most recent data (after 25 years in permafrost conditions prevailing in the same mountain without active cooling) shows that all samples are still viable. Anyone curious about this can for themselves try out various storage temperatures and find out the predicted storage time for specific crops at: http://data.kew.org/sid/viability/

Further I have some reflections regarding some of the recently posted comments. The statement “Most seed resources for plant breeding come from farmers’ fields via national seed stores in developing countries: these countries are not depositing in Svalbard.” is wrong; more than 60% of the deposited material originates from developing countries. Twenty-three of depositors represent national or regional institutes situated in developing counties, 12 are international centers and 28 are from developed countries according to IMF. This data is readily available at: http://www.nordgen.org/sgsv

Finally, a comment about the statement that “Seeds will not be distributed – only ever sent back to the institute that provided them. The reason is that seeds commonly have seed-borne diseases, sometimes nasty viruses and the rest.” This statement is also a misconception. The seeds samples stored in the vault are of the same seed lots already readily distributed worldwide from the depositing institutes. There are more than 1750 plant genetic institutes many of them distributing several thousand samples every year.’

maxted-nigel-Cropped-110x146Nigel Maxted is a senior lecturer in the School of Biosciences at the University of Birmingham. As I suspected, when I commented on Goldenberg’s article, Nigel’s contribution to the discussion was taken out of context. He commented: ‘I believe I have been mis-quoted in this article, I do think the Svalbard genebank is worthwhile and I hope the Trust reach their funding goal, even though ex situ does freeze evolution for the accessions included, it provides our best chance of long-term stability for preserving agrobiodiversity in an increasingly unstable world.

I was trying to make a more nuanced point to Suzanne, that I strongly support complementary conservation that involves both in situ and ex situ actions. However at the moment if we compare the financial commitment to in situ and ex situ conservation of agrobiodiversity, globally over 99% of funding is spent on ex situ alone, therefore by any stretch of the imagination can we be considered to be implementing a complementary approach? I was used to make a point and I suppose it would be naive of me to complain, but I hope one day we will stop trying to create an artificial dichotomy between the two conservation strategies and wake up to the need for real complementary conservation. Conservation that includes a balanced range of in situ actions as well to conservation agrobiodiversity before it is too late for us all.’

HawtinGeoff Hawtin is someone who knows what he’s talking about. As Director General of the International Plant Genetic Resources Institute for just over a decade from 1991, and the founding Executive Secretary of the Global Crop Diversity Trust, Geoff had several telling comments: ‘As someone who has worked for the last 25 years to help conserve the genetic diversity of our food crops, I welcome the article by Suzanne Goldenberg in spite of its very many inaccuracies and misconceptions. She rightly draws attention to the plight of what is arguably the world’s most important resource in the fight against food and nutritional insecurity. If this article results in more attention and funds being devoted to safeguarding this resource—whether on farm or in genebanks—it will have served a useful purpose.

The dichotomy between in situ and ex situ conservation is a false one. The two are entirely complementary and both approaches are vital. For farmers around the world the genetic diversity of their landraces and local varieties is their lifeblood—a living resource that they can use and mould to help meet their current and future needs and those of their families.

But we all live in a world of rapid and momentous change and a world in which we all depend for our food on crops that may have originated continents away. The diversity an African farmer—or plant breeder—needs to improve her maize or beans may well be found in those regions where these crops were originally domesticated – in this case in Latin America, where to this day genetic diversity of these two crops remains greatest. Without the work of genebanks in gathering and maintaining vast collections of such genetic diversity, how can such farmers and breeders hope to have access to the traits they need to develop new crop varieties that can resist or tolerate new diseases and pests, or that can produce higher yields of more nutritious food, or that are able to meet the ever growing threats of heat, drought and flooding posed by climate change?

Scientists have been collecting genetic diversity since at least the 1930s, but efforts expanded significantly in the 1970s and 80s in response to growing recognition that diversity was rapidly disappearing from farmers fields in many parts of the world as a result of major shifts in agricultural production systems and the introduction and adoption of new, higher yielding varieties. Today, thanks to these pioneering efforts, diversity is being conserved in genebanks that no longer exists in the wild or on farmers’ fields.

The common misconception that the Svalbard Global Seed Vault exists to save the world following an apocalyptic disaster is perpetuated, even in the title of the article. In reality, the SGSV is intended to provide a safety-net as a back-up for the world’s more than 1,700 genebanks which themselves, as pointed out in the article, are often far from secure. At a cost of about £6 million to build and annual running and maintenance costs of less than £200,000 surely this ranks as the world’s most inexpensive yet arguably most valuable insurance policy.’

Susan_BragdonFinally, among the genetic resources experts, Susan Bragdon made the following comments: ‘I think the author overstates the fierce debates between the proponents of ex situ and in situ conservation. Most would agree that both are needed with in situ being complemented by ex situ.

The controversy over money is because funders are not understanding this need for both and may feel they have checked off that box by funding Svalbard (which is perhaps better seen as an insurance policy—one never hopes to have to use one’s insurance policy.) Svalbard is of course sexier than the on-farm development and conservation of diversity by small scale farmers around the world. Donors can jet in, go dog sledding, see polar bears. Not as sexy to visit most small-scale farms but there are more and more exceptions (e.g., the Potato Park in Peru)

Articles like this set up a false choice between ex situ and in situ which is simply not shared except by a few loud voices. We need to work together to create the kind of incentives that make small scale farming in agrobiodiverse settings an attractive life choice.’
