Today, we travel to yet another sun-kissed spot, leaving California behind but keeping it legumes. We land in Africa for some ground truths on groundnuts with Vincent Vadez (pictured), groundnut research leader for the Tropical Legumes I (TLI) Project. Vincent fills us in on facts and figures on groundnuts and Africa – a tale of ups and downs, triumphs and trials, but also of  ‘family’ alliances not feuds, and of problems, yes,  but also their present or potential solutions. On to the story then! Read on to find out why groundnuts are…

….A very mixed bag in Africa
Groundnuts (Arachis hypogaea L), also called peanuts, are a significant subsistence and food crop in sub-Saharan Africa. There, groundnuts are grown in practically every country, with the continent accounting for roughly a quarter of the world’s production. Despite this rosy African statistic, problems abound: for example, nearly half (40 percent) of the of the world’s total acreage for groundnuts is in Africa, which dramatically dims the 25 percent global production quota.

In Africa, groundnuts are typically cultivated in moderate rainfall areas across the continent, usually by women.

Clearly then, Africa’s yields are low, borne out by telling statistics which show African production at 950 kilos per hectare, in acute contrast to 1.8 tonnes per hectare in Asia.

…every year, yields worth about USD 500 million are lost”

What ails Africa’s production?
The main constraints hampering higher yields and quality in Africa are intermittent drought due to erratic rainfall, as well as terminal drought during maturation. And that is not all, because foliar (leaf) diseases such as the late leaf spot (LLS) or groundnut rosette are also taking their toll.  Economically speaking, every year, yields worth about USD 500 million are lost to drought, diseases and pests. Plus, the seeding rates for predominantly bushy groundnut types are low, and therefore insufficient to achieve optimal ground cover. Thus, genetic limitations meet and mingle with major agronomic shortcomings in the cultivation of groundnuts, making it…

…. A tough nut to crack
Groundnuts are mostly cultivated by impoverished farmers living in the semi-arid tropics where rainfall is both low and erratic.

Tough it may be for crop scientists, but clearly not too tough for these two youngsters shelling groundnuts at Mhperembe Market, Malawi.

“To help double the productivity of this crop over the next 10 years, we need to improve groundnuts’ ability to resist drought and diseases without farmers needing to purchase costly agricultural inputs,” says Vincent.

But the crop’s genetic structure is complex, plus, for resistance to these stresses, its genetic diversity is narrow. “Groundnuts are therefore difficult and slow to breed using conventional methods,” says Vincent. And yet, as we shall see later, groundnuts are distinctly disadvantaged when it comes to molecular breeding. But first, the good news!

…wild relatives have genes for resisting the stresses… molecular markers can play a critical role”

Why blood is thicker than water, and family black sheep are valued
Kith and kin are key in groundnut science. Vincent points out that groundnuts have several wild relatives that carry the necessary genes for resisting the stresses – especially leaf diseases – to which the crop is susceptible. These genes can be transferred from the wild cousins to the cultivated crop by blending conventional and molecular breeding techniques. But that is easier said than done, because cultivated groundnuts can’t cross naturally with their wild relatives owing to chromosomic differences.

“In modern breeding, molecular markers can play a critical role,” says Vincent. “Using markers, one can know the locations of genes of interest from an agronomic perspective, and we can then transfer these genes from the wild relatives into the groundnut varieties preferred by farmers and their markets.”

[The] ‘variegated’ partnership has been essential for unlocking wild groundnut diversity…”

Partnerships in and out of Africa, core capacities
“Partners are key to this work,” says Vincent. The groundnut work is led by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), with collaborators in the target countries, which are Malawi (Chitedze Agricultural Research Centre), Senegal (Institut sénégalais de recherches agricoles ‒ ISRA) and Tanzania (Agricultural Research Institute, Naliendele), Moving forward together, continuous capacity building for partners in Africa is part and parcel of the project. To this end, there have been several training workshops in core areas such as molecular breeding and phenotyping, farmer field days in the context of participatory varietal selection, as well as longer-term training on more complex topics such as drought, in addition to equipping the partners with the critical infrastructure needed for effective phenotyping.

Further afield out of Africa, Vincent’s team also collaborates with the Brazilian Agricultural Research Corporation (EMBRAPA), France’s Centre de coopération internationale en recherche agronomique pour le développement ‒ CIRAD, and USA’s University of Georgia.

This ‘variegated’ partnership has been essential for unlocking the wild groundnut diversity when about 12 years ago the EMBRAPA team successfully generated a number of ‘synthetic’ groundnuts from their wild relatives. Unlike the wild groundnuts, these synthetic groundnuts can be crossed to the cultivated type, bringing with them treasure troves of beneficial genes pertaining to the wild that would be otherwise unreachable for the cultivated varieties. Taking this one step further, the CIRAD‒ISRA team, in a close North‒South partnership, has used one of the synthetics from the Brazilian programme to generate new genetic diversity in the groundnut cultivar Fleur11. They are using additional synthetics from ICRISAT to further enlarge this genetic diversity in cultivated groundnuts.

These techniques and tools provide signposts on the genome of varieties for characteristics of importance”

A world first for an ‘orphan’, goals achieved, and what next
Among other goals, the team notably achieved a world first: “To produce the first SSR-based genetic linkage map for cultivated groundnuts!” declares Vincent. SSR stands for simple sequence repeat. The map was published in 2009,  followed later on by a groundnut consensus map in 2012.

But what do these maps and their publication mean for groundnut production? Vincent explains: “These techniques and tools provide signposts on the genome of varieties for characteristics of importance ‒ for instance, resistance to a disease ‒ and these are used in combination to speed up the development of groundnut varieties that are more resistant to the stresses found in the harsh environments where most of the tropical world’s poor farmers live. Accelerating development means quicker delivery to farmers who are at high risk of going hungry. TLI Phase I produced synthetic groundnuts with new genes for disease resistance.”

In Phase II of the TLI Project which terminates in mid-2014, the team has continued to identify new genetic and genomic resources, for instance new sources of drought resistance from the germplasm and which are currently being used in the development of new breeding stocks. What is significant about this is that groundnuts ‒ like most other members of the legume family ‒ do not have much in the way of genomic and molecular-genetic resources, and are in fact consequently referred to in some circles as ‘orphans’ of the genome revolution. The focus has also been on resistance to rust, early and late leaf spot, and rosette – all economically critical diseases – by tapping the resilience of GBPD4, a cultivar resistant to rust and leaf spot, and introducing its dual resistance to fortify the most popular varieties against these diseases. The team also hopes to scale up these promising examples.

We believe this team is firmly on the way to fulfilling their two-fold project objectives which were: (1) to develop genomic resources and produce the first molecular-breeding products of the crop by injecting  disease resistance (from TLI Phase I work) into farmer- and market-preferred varieties; and, (2)  to lay the foundation for future marker-assisted recurrent selection (MARS) breeding by tapping on newly identified sources of drought tolerance.

 the genetic stocks that hold the most promise to overcome leaf disease are found in the wild relatives… A thorough reflection is needed to combine good genetics with sound agronomic management”

The future
But the team is not resting on their laurels, as the work will not stop with the fulfillment of project objectives. In many ways, their achievements are in fact just the beginning. The new breeding stocks developed during TLI Phase II need to be evaluated further for their drought tolerance and disease resistance prior to their deployment in breeding programmes, and this activity ‒ among others ‒ is included for the next phase of the work in the proposed Tropical Legumes III project. In particular, the genetic stocks that hold the most promise to overcome leaf disease are found in the wild relatives. Thus, the existing materials need to be fully exploited and more need to be produced to cover the full breadth of potential stresses. Vincent adds “Of course an increasing part of the efforts will be about assuring quality evaluation data, meaning we must continue to significantly enhance the capacity ‒ both human and physical ‒ of our partners in target countries. Last but not least, the good wheat and rice cultivars that directly arose from the green revolution would have been nothing without nitrogen fertiliser and irrigation.” Vincent adds that the same applies to groundnuts: they are cultivated in infertile soil, at seeding rates that are unlikely to optimise productivity.

For this reason, and others explained above, “A thorough reflection is needed to combine good genetics with sound agronomic management,” Vincent concludes, stressing the importance of what he terms as ‘looking beyond  the fence’. Vincent’s parting shot, as our conversation draws to close: “In fact, I have grown increasingly convinced over the past year that we probably overlook those agronomic aspects in our genetic improvements at our peril, and we clearly need a re-think of how to better combine genetic improvement with the  most suitable and farmer-acceptable agronomic management of the crop.”

Much food for thought there! And probably the beginnings of an animated conversation to which a groundnut crop model, on which Vincent and team are currently working, could soon yield some interesting answers on the most suitable genetic-by-management packages, and therefore guide the most adequate targets for crop improvement.

Made in Bangladesh: 2-in-1 salt-and-water rice ‘sandwich’ with Filipino filling and Atlantis touch

Two in one, in more ways than one
Armin Bhuiya

Armin Bhuiya

Armin Bhuiya (pictured) is a dynamic and lively young geneticist and plant breeder, who has made huge strides in tracking crucial  genes in Bangladeshi rice landraces (or traditional farmer varieties). Armin took a ‘sandwich’ approach twinning two traits  – salt and submergence tolerance – in order to boost farmers’ yields. Her quest for salt-impervious ‘amphibian’ rice has seen her cross frontiers to The Philippines, and back to her native Bangladesh with solutions that will make a difference, borrowing a leaf along the way from the mythical submarine world of Atlantis for life under water. Using cutting-edge crop science, Armin is literally recreating out-of-this-world stuff working two elements of the ancient world – earth and water – plus that commodity that was then so prized enjoying a  premium comparable to gems: salt. Read on! 

A rice heritage, and the ‘sandwich’ saga and submarine search both begin…

“My father worked at the Bangladesh Rice Research Institute (BRRI), which basically means I grew up in rice research. You could say that I was born and bred in agriculture and this inspired me to study agriculture myself,” says Armin. As a result of these early experiences, Armin started a master’s degree in 2006 on genetics and plant breeding, specialising in hybrid rice. Ever since, rice has been her religion, following in the footsteps of her father to join the Bangladesh Rice Research Institute (BRRI).

Her other defining hallmark is her two-in-one approach. Sample this: once she completed her two-in-one master’s, Armin went on to study for a PhD in the same twin areas at Bangladesh Agricultural University. Pondering long and hard on what research would be of most practical use, she asked herself “What is the need? What research will be useful for my country and for the world?” (Editorial aside: out of this world work, apparently…)

Not content  pondering  over the question by herself, her natural two-track approach kicked in. Mulling with her colleagues from BRRI, the answer, it first seemed, was to find ways to produce salt-tolerant high-yielding rice. In Bangladesh and many other parts of South and Southeast Asia, climate change is driving up the sea level, spreading salinity further and deeper across low-lying coastal rice-fields, beyond the bounds where salt-drenched terrain has long been a perennial problem. Modern rice varieties are highly sensitive to salt. So, despite the low yields and quality, farmers continue to favour hardy traditional rice landraces that can take the heat and hit from the salt. Proceeding from this earthy farmer reality and inverting the research–development continuum, Armin needed no further thinking as the farmers showed the way to go. Her role and the difference she could make was to track the ‘treasure’ genes locked in these landraces that were transferred to high-yielding but salt-sensitive rice varieties, to fortify them against salt.

But that was not all. There’s power in numbers and consulting others, harnessing the best in diversity. In comes the two-track approach again, with Armin now turning to fellow scientists again, with the reality from farmers. Upon further consultations with colleagues, yet another fundamental facet emerged that could not be ignored. Apparently, salt-impervious rice alone would not be not enough, and here’s why. Salt and tides aside, during the rainy season inland, flash floods regularly submerge the fields, literally drowning the crop. More than 20 million hectares in South and Southeast Asia are affected – including two million hectares in coastal Bangladesh alone. The southern belt of Bangladesh is particularly affected, as modern varieties are sensitive to not only submergence but also salinity. So Armin had her work cut out for her, and she now knew that for the fruit of her labour to boost rice production in coastal regions as well (two tracks again! Inland and coastal low-lying rice-lands), what she needed to do was to work on producing high-yielding, salt-impervious, ‘amphibian’ rice that could withstand not only salinity but also submarine life. In other words, pretty much rice for a latter-day real-life rendition of the mythical Atlantis.

Armin has successfully incorporated dual tolerance to salinity and submergence in the popular Bangladeshi mega-variety BR11. This will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.”

Through the door of opportunity
The opportunity that opened the door for Armin to fulfil her dream was a DuPont Pioneer postgraduate fellowship implemented by GCP. The competitive programme provides grants for postgraduate study in plant breeding and genetics to boost the yields of staple food crops. This fellowship took Armin to Filipino shores and the molecular breeding labs at the International Rice Research Institute (IRRI). Here she got what she terms a golden opportunity to work under the tutelage of Abdelbagi Ismail, a leading plant physiologist focusing on overcoming abiotic stresses. From him, Armin learnt how carry out the precise meticulous research required for identifying quantitative trait loci (QTLs).

Armin conducted her research with two different mapping populations, both derived from Bangladeshi landraces (Kutipatnai and Ashfal). She found a total of nine quantitative trait loci (QTLs) from one mapping population and 82 QTLs from another for tolerance to salinity stress at seedling stage (QTL is a gene locus where allelic variation is associated with variation in a quantitative trait). Incorporating these additional genes into a high-yielding variety will help to develop promising salt-tolerant varieties in future. She has also successfully incorporated QTLs for dual tolerance to salinity (Saltol) and submergence (Sub1) in the popular Bangladeshi mega-variety, BR11. Stacking (or ‘pyramiding’ in technical terms) Saltol and Sub1 QTLs in BR11 will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.

I know what to do and what is needed… I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students”

Dream achiever and sharer: aspiring leader inspiring change
The Pioneer–GCP fellowship has given Armin the opportunity to progress professionally. But, more than that, it means that through this remarkable young scientist, others from BRRI will benefit – as will her country and region. “While I was at IRRI,” Armin says, “I trained myself in modern molecular plant-breeding methods, as I knew that this practical experience in high-tech research methods would definitely help Bangladesh. I know what to do and what is needed. I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students. It makes me very happy and my parents very proud that the fellowship has helped me to make my dream come true.”

Away from professional life, there have been benefits at home too, with these benefits delivered with Armin’s aplomb and signature style in science – doing two in one, in more ways than one. This time around, the approach has led to dual doctorates for a dual-career couple in different disciplines: “When I went to The Philippines” Armin reveals, “my husband decided to come with me, and took the opportunity to study for a PhD in development communications. So we were both doing research at the same time!”

While Armin’s research promises to make a real difference in coastal rice-growing areas, Armin herself has the potential to lead modern plant breeding at her institute, carry GCP work forward in the long term, post-GCP, and to inspire others as she herself was inspired – to make dreams come true and stimulate change. An inspired rice scientist is herself an inspiration. You will agree with us that Armin personifies Inspiring change, our favoured sub-theme for International Women’s Day this year.

Go, Armin, Go! We’re mighty proud of what you’ve achieved, which we have no doubt serves as inspiration for others!

‘Frontier’ science and Rebecca’s ‘fire’ – enlisting nature to fortify crops against disease

Restless Rebecca
Rebecca Nelson

Rebecca Nelson

I’m a mother and a wife. The idea of so many mothers not being able to feed their families, and so many children not getting the nutrients they need to reach their potential, has always pained me.” – Rebecca Nelson (pictured), Professor, Plant Pathology and Plant-Microbe Biology, Cornell University, USA

In this dispatch from the ‘frontline’, fired up and leading the charge against crop disease is ‘frontier’ scientist, restless Rebecca Nelson. Where does Rebecca’s restlessness and consequent fire come from? She says it has always bothered her that a billion people go hungry every single day…

Wrestling Rebecca: feeding families one disease-resistant crop at a time
Wanting to remedy this billion-strong calamity, Rebecca has spent the last quarter century working with national and international institutes in Asia, Africa and the Americas. During this time, she has focused on understanding the ways in which plants defend themselves against diseases.

“An amazing percentage of crops are lost to pests and diseases in the developing world each year, which in turn leads to lack of food and impoverishes local economies,” she says. “These farmers can’t afford the herbicides and pesticides that developed-world farmers use to protect their crops, and those are not great solutions to the problems anyway. So it’s important to find ways to help these crops defend themselves.”

This means identifying crops with disease-resistant traits and using them to breed disease-resistant crops with long-lasting protection from a multitude of diseases.

We were really grateful that the GCP funded us so we could continue to understand and build resistance to rice blast and bacterial blight, and to connect the work on rice and maize”

Travels and travails to make a difference
After completing a PhD in zoology at the University of Washington, USA, in 1988, Rebecca spent eight years in The Philippines at the International Rice Research Institute (IRRI) and then five years at the International Potato Center in Peru. “I wanted to get out into the world and try and have a practical impact instead of doing research for the sake of research,” she says.

During her time in The Philippines, Rebecca worked on several rice disease-resistance projects. She was to continue many of these projects nine years later, as part of her GCP project – Targeted discovery of superior disease QTL alleles in the maize and rice. “We were really grateful that GCP funded us so we could continue to understand and build resistance to rice blast and bacterial blight, and to connect the work on rice and maize,” she says.

Rebecca was also delighted to involve her IRRI mentor, Hei Leung (then a GCP Subprogramme Leader for genomics), and friend, Masdiar Bustamam, of the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD). During her time at IRRI, Rebecca and her IRRI team had worked with Masdiar to establish her laboratory. “It was really pleasing to have Masdiar participate in the project and to see how far she and her lab had come since our earlier collaboration. The difference is that they now made a markedly significant contribution to the project in advancing the understanding of inheritance of rice blast and sheath blast resistance, and they developed germplasm that has really good resistance to these diseases.”

I’ve always been grateful to GCP for supporting me at that transitional stage in my career…. [I] was a relative newbie when it came to working with maize. However, I was lucky to have some really great collaborators…James helped me a lot at the start of the project and throughout. Even though our project is finished, we have teamed up on a number of other projects to continue what we started.“

Tentative transition from rice to maize; shunting between class and grant-giving
Despite winning a merit-based competitive grant, Rebecca confesses she wasn’t sure GCP would accept her proposal, owing to her  then limited experience in maize research. “I’ve always been grateful to GCP for supporting me at that transitional stage in my career. I’d just returned from Peru and taken up a position at Cornell and was at that time a relative newbie when it came to working with maize. However, I was lucky to have some really great collaborators.”

One such collaborator, who Rebecca is thankful to have had on her project, was James Gethi, of the Kenya Agricultural Research Institute (KARI), and a leading researcher in Kenya. At the time, James was a recent Cornell graduate who was returning home to help bolster his nation’s crop-research capabilities. “James helped me a lot at the start of the project and throughout. Even though our project is finished, we have teamed up on a number of other projects to continue what we started.”

At Cornell, Rebecca oversees her own laboratory and still finds time to teach a class on international agriculture and rural development. She also serves as scientific director for the McKnight Foundation’s Collaborative Crop Research Program (CCRP), a grants programme funding agricultural research in developing countries.

Growing up with science…and a moderate Rebecca rebellion!
As our conversation draws to a close, Rebecca reveals she is currently skyping from the bedroom she grew up in, in Bethesda, Maryland, half an hour from downtown Washington DC, USA. “I’m down visiting my parents before I jet off to West Africa tomorrow,” she says where she is carrying out her CCRP commitments.

Rebecca credits her parents for encouraging her scientific inquisitiveness and determination to aid those in need. “Both of my parents are physicians, as is my younger brother. I thought I was a rebel with my interest in agriculture, but my younger sister is a farmer and agroecologist, so I guess we’re both straddling agriculture and science,” Rebecca says with a laugh.

“In all honesty though, my parents encouraged all of us to follow what we were fascinated by and passionate about, and for me and my sister, that was agriculture. We reared goats in our suburban backyard, dissected animal road-kills on the kitchen table and even turned the  family swimming pool into a fish-pond because we wanted to learn about fish farming!” Rebecca recollects with great fondness.

I still get a kick out of trying to understand the biology of disease resistance and to try to help develop disease-resistant crops, which will help alleviate the fallout from crop failure and subsequent food shortages in developing nations”

Wife and mum, manager and mentor, and what gives Rebecca a kick
Rebecca says she and her journalist husband, Jonathan Miller, try to encourage their two sons, William and Benjamin, in the same manner. She also says she uses a similar theory as a mentor. “I love interacting with the young talent and I like to think I’ve grown as a person the more that I’ve evolved as a manager and mentor.”

Although she spends most of her time at her desk or on a plane or in a meeting room, Rebecca is always keen to jump back into the field and familiarise herself with the science she is overseeing. “I still get a kick out of trying to understand the biology of disease resistance and to try to help develop disease-resistant crops, which will help alleviate the fallout from crop failure and subsequent food shortages in developing nations.”

Generation next for plant breeding

A shared vision

What is GCP all about and why is its work important? Why was GCP created? Read recollections from key people involved in GCP’s conceptualisation, and find out how realisation of the shared vision continues today. Featuring candid conversations with Masa Iwanaga, former Director General, CIMMYT; Dave Hoisington, Consortium Committee Chair; Andrew Bennett, Executive Board member; and Jean-Marcel Ribaut, GCP Director.

When was the last time you went to your local shop to buy something only to be told they’ve run out of it? How did you react? Like most of us, did you question how they could have run out – after all, isn’t it their business to adequately supply the demand?

Most likely you just went to another store. But what if there wasn’t another store around that had your product, or worse, there was actually a national shortage of your product? This is the reality that faces not just those after the latest iPad, but billions of people who just want something, anything, to eat.

With less productive land on which to grow crops, a more variable climate and more extreme weather events, farmers across all continents are struggling to produce crops, let alone increase yields to meet an ever-growing demand.

This scenario has continually raised its ugly head over the last 200 years as the world’s population has grown exponentially and shifted to urban surroundings. If not for the Green Revolution, inspired by the late Norman Borlaug’s agricultural development research within the Office of Special Studies in Mexico (now the International Maize and Wheat Improvement Center, more commonly known as CIMMYT, its Spanish acronym), the world population would have already suffered losses into the billions.

Even so, food insecurity is still recognised as a global challenge by the UN’s Food and Agriculture Organization (FAO). While there is debate over the cause for such insecurity, the advances of agricultural technology born from a Mexican-flavoured research programme are once again coming to the fore to meet the challenge.

Genebanks are not limited to conservation but are also a source of new alleles for crop improvement.

The genies in the genebank
Seedbank collections serve as insurance against unanticipated future threats to food security, the degradation of our environment and the loss of plant biodiversity.

But that is not all: the banks are not limited to conservation but are also a source of new alleles for crop improvement. The temperature-controlled CGIAR genebanks are a veritable treasure trove for plant breeding. Over the past four decades, their curators have scoured the planet, collecting, categorising and conserving more than 650,000 samples of crop, forage and agroforestry genetic resources, held in trust on behalf of humanity.

One such temperature-controlled genebank is located just outside the sweltering Mexico City: the CIMMYT genebank holds more than 150,000 unique samples of wheat and its relatives from more than 100 countries – said to be the largest collection of a single crop.

While genebank ‘stocks’ have always been open to plant breeders, it wasn’t until 2002 that CGIAR researchers embarked on a more structured and systematic approach using modern technologies to tap their breeding potential, thereby elevating the genebanks beyond their traditional collection and conservation role. Prior to that, far-sighted individual pioneering researchers had been studying (termed ‘screening’ in breeder-speak) the stocks for solutions to breeding problems and to improve crops, but the turning point for a concerted ‘institutional’ effort, would come in the early noughties.

By studying the genes of wild versions of, let’s say, wheat, researchers can find genes that could help cultivated wheat to better battle drought.

The dawn of a new generation
One of these researchers was Dave Hoisington (pictured), then with CIMMYT, and now Chair of GCP’s Consortium Committee, and ICRISAT’s Director of Research. Dave worked with the then newly appointed CIMMYT Director General, Masa Iwanaga, and helped draft a joint proposal with other institutes to CGIAR to form a Challenge Programme that could use the recent advances in molecular biology to harness their rich global stocks of crop genetic resources to create and provide a new generation of plants to meet farmers’ needs. This successfully gave rise to the CGIAR Generation Challenge Programme.

“GCP’s first task was to go in and identify the genetic wealth held within the CGIAR banks,” says Dave.

“To do this, we wanted to use the most recent molecular tools, like molecular markers, to help scan the genomes and discover genes in species related to crops of interest that could help increase yield.”

Let’s use an analogy from a familiar medium – text: think of this story you are now reading as the plant’s genome, its words as its genes and a molecular marker as a text highlighter. You can use different markers to highlight different keywords in this story. Once you can see these keywords, you can then study them in more detail, and, in the case of genes, see what they control in the plant, and how they affect its different aspects.

“At that time, we recognised that a Centre like CIMMYT could no longer undertake this tremendously complex task on its own,” recounts Masa (pictured).”We needed to work within a programme that could concentrate on the task and that rallied together various CGIAR Centres as well as research institutes outside CGIAR, especially in developing countries.”

Partnerships with spirit
Partnerships have always been a key ingredient to success. At the same time, they have led to the downfall of many projects.

Back in the early noughties, CGIAR recognised their business model and research system were not actively fostering partnerships between their different research Centres as much as they should have been, nor were they vigorously encouraging Centres to seek collaboration outside CGIAR.

This was one of the fundamental reasons for establishing the Challenge Programmes, says Jean-Marcel Ribaut (pictured), who, in his role as GCP Director, has been credited by the Board and Committee for the significant time he has taken to broker, nurture and manage GCP’s partnerships.

“One of our major outputs has been the human assets,” says Jean-Marcel with great pride. “We have created this amazing chain of people from the lab to the field.”

In fact, GCPs greatest asset – its ‘crown jewel’ – is its network of people and the capacity the Programme provides them with to buttress all the hard work, particularly in countries where the end products (crops) will be of most benefit.

…the GCP Spirit’ … is visible and palpable: you can recognise people working with us have a spirit that is typical of the Programme.”

“To make a difference in rural development, to truly contribute to improved food security through crop improvement and income for poor farmers, we knew we had to build capacity in these areas,” observes Jean-Marcel.

“I see our management style as fairly ‘paternal’, in the positive sense of wanting to see these groups of people succeed, and us helping them to do so. If a research site needs a pump for fieldwork, we work with a local or international consultant who will visit the partner and evaluate their needs, advise them on what type of pump they need, as well as other infrastructure they’ll need for the whole system to be sustainable. We’ll then provide training on how to use the pump most effectively. It’s an investment in the people as much as in the products they are working on because we are trying to change the system of how science within partnerships is conducted and supported, as much as we are trying tap genetic diversity and breed resilient crops for the developing world.”

We were attracted to GCP because of its strong facilitating role, which offered considerable support to addressing the bottlenecks associated with research programmes that researchers and CGIAR identified.”

This support and change have been major selling points for potential partners who have resonated with what Jean-Marcel calls ‘the GCP Spirit’ – partners open to sharing their skills, tools and knowledge, willing to sacrifice their views and leadership and, most importantly, support one another.

“It is visible and palpable: you can recognise people working with us have a spirit that is typical of the Programme,” says Jean-Marcel.

Funders like the Swiss Agency for Development and Cooperation (SDC) are attracted to, and impressed by, GCP’s approach as an honest and impartial ‘broker’.

“We were attracted to GCP because of its strong facilitating role, which offered considerable support to addressing the bottlenecks associated with research programmes that researchers and CGIAR identified,” says Carmen Thönnissen (pictured), Senior Advisor at SDC.

“GCP is also in line with SDC’s internal guidelines on Green Biotechnology, where it is our aim not to support single-donor initiatives but to work in larger programmes that have a clear focus on strengthening the national partner capacities too.”

At the beginning, most project leaders were from developed nations and CGIAR Centres. … now more than half of our projects are led by scientists in developing countries.”

A structured revolution within an evolution: aiming for products and sustainable change
GCP was designed in two phases over its 10-year life. The first was about the research and using genetic plant breeding techniques. The second and current phase focuses more on accessing modern breeding technologies and building capacity in developing countries to do the research for themselves.

Within nine years, GCP has produced useful tools and products from its studies of genetic resources.
These products have contributed to advancing knowledge, and will continue to do so into the future, particularly in plant breeding.

“At the very beginning, most project leaders were from established universities and institutes  in developed nations, and CGIAR Centres. However, over time there has been a major shift and now we are proud that more than half of our projects are led by scientists in developing countries,” says Jean-Marcel. “They’ve moved from the position of implementers to the role of leaders, while the CGIAR Centres and institutes in developed countries have evolved more into mentors and teachers. We hope this empowerment will allow national programmes to grow and establish themselves to be sustainable when the funding dries up.”

Challenges within the Challenge Programme
All this talk about spirit, collaboration and partnerships does make it sound as if GCP has found the winning formula, but Jean-Marcel is quick to counter such notions, and there have been constant course corrections in charting the Programme’s path. “If anything, our strength comes from recognising our weaknesses, acknowledging that we don’t have it all worked out, and embracing change where it is needed.”

A mid-term external review was conducted in 2008 to audit the Programme’s weaknesses, strengths and lessons learnt from both. This review resulted in some governance reforming, bringing about the Consortium Committee and an independent Executive Board.

“It’s a major improvement that we have an independent Board, allowing for focus, and without any conflict of interest. I think they are doing a great job,” says Jean-Marcel. “They are monitoring and evaluating what we are doing, providing plenty of feedback and ideas on how to move forward, and contributing a lot to the success of the Programme.”

The Board’s focus now turns to auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so they can continue to deliver products and capacity to the developing world.

Bird’s eye view from the Board
With more than 45 years of experience in international development and disaster management and, having worked in development programmes in Africa, Asia, Latin America, the Pacific and the Caribbean, Andrew Bennett (pictured) was a perfect candidate for the Board Chair.

“We are committed to the role that can be played by science in development, and to the Programme,” says Andrew. “We have offered advice and helped the Programme’s Consortium Committee and management refocus the Programme. By all accounts, they seem happy with how things have evolved.”

Advice and helping aren’t normally the words associated with how a Board works but, like so much of the GCP family, this isn’t a classical board.

Andrew explains “Because GCP is hosted by CIMMYT, the Board does not have to deal with any policy issues. That is the responsibility of the Consortium Committee. Our role is more to provide advice and to help with decision-making and implementation, which is great as we’ve been able to focus on the Programme’s science and people.”

That focus now turns to auditing the Programme and mapping a strategy to sustain its successful partnerships and systems, so they can continue to deliver products and capacity to the developing world.

Turning sunset to sunrise
With only two-and-a-half years left to run, Jean-Marcel and his team are working just as passionately on sustaining the partnerships, projects and outputs that GCP has created.

“We knew we weren’t going to be around forever, so we had a plan from early on to hand over the managerial reins to other institutes, including CGIAR,” says Jean-Marcel, with the slight affliction of a parent helping their child move out of home.

“We have begun integrating projects into the CGIAR Research Programmes (CRPs) which we hope will allow them to continue to grow and work effectively towards the goals set.”

At the same time, the Management Team, Committee and Board are all busy auditing the successes and failures of the Programme to quantify the achievements of what has been termed as one of the CGIAR’s more successful Challenge Programmes, and on how to make GCP products freely accessible to other research institutes and programmes.
