Jeff Ehlers

Our guest today is Jeff Ehlers (pictured), Programme Officer at the Bill & Melinda Gates Foundation. Jeff’s an old friend of GCP, most familiar to the GCP community in his immediate past stomping grounds at the University of California, Riverside (UCR), USA, leading our research to improve cowpea production in the tropics, for which sunny California offers a perfect spot for effective phenotyping. Even then, Jeff was not new to CGIAR, as we’ll see from his career crossings. But let’s not get ahead of ourselves in narrating Jeff’s tale. First, what would high-end cowpea research have to do with crusading and catapults? Only Jeff can tell us, so please do read on!

The GCP model was a very important way of doing business for CGIAR and the broader development community, enabling partnerships between international research institutes, country programmes and CGIAR. This is particularly important as the possibilities of genomics-led breeding become even greater…If anything, we need to see more of this collaborative model.”

Growing green, sowing the seed, trading glory for grassroots
Growing up in USA’s Golden State of California, green-fingered Jeff had a passion for cultivating the land rather than laboratory samples, harbouring keen ambitions to become a farmer. This did not change with the years as he transited from childhood to adolescence. The child grew into a youth who was an avid gardener: in his student days, Jeff threw his energy into creating a community garden project ‒ an initiative which promptly caught the eye of his high school counsellor, who suggested Jeff give the Plant Science Department at UCR a go for undergraduate studies.

And thus the seeds of a positively blooming career in crop research were sown. However, remaining true to the mission inspired by his former community-centred stomping grounds, a grassroots focus triumphed over glory-hunting for Jeff, who – no stranger to rolling his sleeves up and getting his fingers into the sod – found himself, when at the University of California, Davis, for his advanced studies, embarking on what was to become a lifelong undertaking, first at the International Institute of Tropical Agriculture (IITA) and then at UCR, dedicated to a then under-invested plant species straggler threatening to fall by the research world’s wayside. With a plethora of potential genomic resources and modern breeding tools yet to be tapped into, Jeff’s cowpea crusade had begun in earnest…

GCP’s TLI was essential in opening that door and putting us on the path to increased capability – both for cowpea research enablement and human capacity”

Straggler no more: stardom beckons, and a place at the table for the ‘orphan’
And waiting in the wings to help Jeff along his chosen path was the Generation Challenge Programme (GCP), which, in 2007, commissioned Jeff’s team to tackle the cowpea component of the flagship Tropical Legumes I (TLI) project, implemented by GCP under the Legumes Research Initiative. TLI is mainly funded by the Bill & Melinda Gates Foundation. The significance of this project, Jeff explains, was considerable: “The investment came at a very opportune time, and demonstrated great foresight on the part of both GCP and the Foundation.” Prior to this initiative, he further explains, “there had been no investment by anyone else to allow these orphan crops to participate in the feast of technologies and tools suddenly available and that other major crops were aggressively getting into. Before GCP and Gates funding for TLI came along, it was impossible to think about doing any kind of modern breeding in the orphan grain legume crops. GCP’s TLI was essential in opening that door and putting us on the path to increased capability – both for cowpea research enablement and human capacity.”

Left to right: Wellington Muchero, Ndeye Ndack Diop (familiar, right?!), Raymond Fenton, Jeff Ehlers, Philip Roberts and Timothy Close in a greenhouse on the UCR campus, with cowpeas in the background. Ndeye Ndack and Jeff seem to love upstaging each other. She came to UCR as a postdoc working under Jeff, then she moved to GCP, with oversight over the TLI project, thereby becoming Jeff’s boss, then he moved to the Foundation with oversight over TLI. So, what do you think might be our Ndeye Ndack’s next stop once GCP winds up in 2014? One can reasonably speculate….!

Of capacity building, genomics and ‘X-ray’ eyes
This capacity-building cornerstone – which, in the case of the TLI project, is mainly funded by the European Commission – is, says Jeff, a crucial key to unlocking the potential of plant science globally. “The next generation of crop scientists ‒ particularly breeders ‒ need to be educated in the area of genomics and genomics-led breeding.”

While stressing the need for robust conventional breeding efforts, Jeff continues: ”Genomics gives the breeder X-ray eyes into the breeding programme, bringing new insights and precision that were previously unavailable.”

In this regard, Jeff has played a leading role in supporting skill development and organising training for his team members and colleagues across sub-Saharan Africa, meaning that partners from Mozambique, Burkina Faso and Senegal, among others, are now, in Phase II of the TLI project, moving full steam ahead with marker-assisted and backcross legume breeding at national level, thanks to the genotyping platform and genetic fingerprints from Phase I of the project. The genotyping platform, which is now publicly available to anyone looking to undertake marker-assisted breeding for cowpeas, is being widely used by research teams not only in Africa but also in China. Thanks in part then to Jeff and his team, the wheels of the genomics revolution for cowpeas are well and truly in motion.

Undergoing the transition from phenotypic old-school plant breeder to modern breeder with all the skills required was a struggle…it was challenging to teach others the tools when I didn’t know them myself!…without GCP, I would not have been able to grow in this way.”

Talking about a revolution, comrades-in-arms, and a master mastering some more
But as would be expected, the road to revolution has not always been entirely smooth. Reflecting on some of the challenges he encountered in the early TLI days, and highlighting the need to invest not only in new students, but also in upgrading the existing skills of older scientists, Jeff tells of a personal frustration that had him battling it out alongside the best of them: “Undergoing the transition from phenotypic old-school plant breeder to modern breeder with all the skills required was a struggle,” he confides, continuing: “It was challenging to teach others the tools when I didn’t know them myself!”

Thus, in collaboration with his cowpea comrades from the global North and South, Jeff braved the steep learning curve before him, and came out on the other side smiling – an accomplishment he is quick to credit to GCP: “It was a very interesting and fruitful experience, and without GCP, I would not have been able to grow in this way,” he reveals. Holding the collaborative efforts facilitated by the broad GCP network particularly dear, Jeff continues: “The GCP model was a very important way of doing business for CGIAR and the broader development community, enabling partnerships between international research institutes, country programmes and CGIAR. This is particularly important as the possibilities of genomics-led breeding become even greater…If anything, we need to see more of this collaborative model.”

GCP’s Integrated Breeding Platform addresses the lack of modern breeding skills in the breeding community as a whole, globally…The Platform provides extremely valuable and much-needed resources for many public peers around the world, especially in Africa…”

One initiative which has proved especially useful in giving researchers a leg up in the mastery of modern breeding tools, Jeff asserts, is GCP’s Integrated Breeding Platform (IBP): “IBP addresses the lack of modern breeding skills in the breeding community as a whole, globally. By providing training in the use of genomic tools that are becoming available, from electronic capture of data through to genotyping, phenotyping, and all the way to selective decision-making and analysis of results, IBP will play a critical role in helping folks to leverage on the genomics revolution that’s currently unfolding,” Jeff enthuses, expanding: “The Platform provides extremely valuable and much-needed resources for many public peers around the world, especially in Africa where such one-off tools that are available commercially would be otherwise out of reach.”

Conqueror caparisoned to catapult: life on the fast lane and aiming higher
Well-versed in conquering the seemingly unobtainable, Jeff shares some pearls of wisdom for young budding crop scientists:”Be motivated by the mission, and the ideas and the science, and not by what’s easy, or by what brings you the most immediate gratification,” he advises, going on to explain: “Cowpeas have been through some really tough times. Yet, my partners and I stuck it out, remained dedicated and kept working.” And the proof of Jeff’s persistence is very much in the pudding, with his team at UCR having become widely acclaimed for their success in catapulting cowpeas into the fast lane of crop research.

It was a success that led him to the hallways of the Bill & Melinda Gates Foundation, where, after two decades at UCR, Jeff is currently broadening his legume love affair to also embrace beans, groundnuts, chickpeas, pigeonpeas and soya beans.

Here, our conquering crusader is ‘helmeted’ in an ICRISAT cap, even if not horsed and caparisoned for this ‘peacetime’ pigeonpea mission!

On his future professional aspirations, he says: “The funding cut-backs for agriculture which started before 1990 or so gutted a lot of the capacity in the public sector, both in the national programmes in Africa but also beyond. I hope to play a role in rebuilding some of the capacity to ensure that people take full advantage of the technical resources available, and to enable breeding programmes to function at a higher level than they do now.”

Next to Jeff is Emmanuel Monyo, the coordinator of the Tropical Legumes II (TLII) project – TLI’s twin – whose brief is seed multiplication. TLII is therefore responsible for translating research outputs from TLI into tangible products in the form of improved legume varieties.

Whilst it’s been several years since he donned his wellington boots for the gardening project of his youth, what’s clear in this closing statement is an unremitting and deeply ingrained sense of community spirit – albeit with a global outlook – and a fight for the greater good that remain at the core of Jeff’s professional philosophy today.

No doubt, our cowpea champion and his colleagues have come a long way, with foundations now firmly laid for modern breeding in the crop on a global scale, and – thanks to channels now being established to achieve the same for close relatives of the species – all signs indicate that the best is yet to come!

Two peas in a pod, hand in hand,

Elizabeth Parkes

“In the past, the assumption was always that ‘Africa can’t do this.’ Now, people see that when given a chance to get round circumstances – as GCP has done for us through the provision of resources, motivation, encouragement and training – Africa can achieve so much!…GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner…Building human capacity is my greatest joy….I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well. To see a talented woman researcher firmly established in her career and with her kids around her is thrilling….Rural families are held together by women, so if you are able to change their lot, you can make a real mark…” – Elizabeth Parkes, cassava researcher, Ghana

Elizabeth’s PhD is on cassava genetic diversity, combining ability, stability and farmer preference in Ghana. But for Elizabeth, it is not the academic laurels and limelight but rather, a broader vision of social justice which really drives her: “I see African communities where poverty and hunger are seemingly huge problems with no way out; I’m fortunate to be working on a crop whereby, if I put in enough effort, I can bring some solutions. My primary target group in my research is the less privileged, and women in particular have been my friends throughout. Rural families are held together by women, so if you are able to change their lot, you can make a real mark.”

…agricultural research was a man’s job!”

A perennial passion for cassava, and walking with giants: Elizabeth with the pick of the crop for the 2014 cassava harvest season at IITA, Ibadan, Nigeria.

Prowess and prejudice: Breaking the mould and pioneering into pastures new
On first tentatively dipping her toe into the professional waters of crop science when growing up in her native Ghana, initial reactions from her nearest and dearest suggested that carving out a name for herself in her career of choice was never going to be a walk in the park: “As an only girl among eight boys of whom three were half-siblings, and the youngest child, my father was not very amused; he thought agricultural research was a man’s job!” she recalls. Undeterred and ever more determined to turn this commonly held canard on its head, Elizabeth went on to bag a Bachelor’s degree in Agriculture, a diploma in Education, and an MPhil degree in Crop Science. During a stint of national service between academic degrees, she approached a scientist engaged in root and tuber projects at Ghana’s Council for Scientific and Industrial Research (CSIR) Crops Research Institute (CRI), offering to carry out some research on cassava, and soon establishing the institute’s first trials in Techiman, in the Brong Ahafo Region,where she was doing her national service. Recognising all the hallmarks of a great scientist, nurturer and leader, her CRI colleagues were quick to welcome this fresh talent into the fold as an Assistant Research Officer, with the full treasure trove of root tuber crops – from cassava to sweet potato to yam and cocoyam, among others – all falling under her remit. Not a bad start for the first woman to be assigned to the project!

Quickly proving herself as a fiercely cerebral researcher with a natural knack for the plant sciences, Elizabeth was encouraged by seasoned (then) GCP scientist, Martin Fregene (their paths had crossed during Elizabeth’s master’s degree thanks to research collaboration with the International Institute of Tropical Agriculture – IITA), to embark on a PhD degree with a focus on cassava. Coinciding with an era when links between Martin’s then home institute, the International Center for Tropical Agriculture (CIAT) and GCP were beginning to really take off the ground, it was a move that proved timely, and a path which Elizabeth pursued with her characteristic vigour and aplomb, climbing the GCP research ranks from multiple travel-grant recipient to a research fellow, and, more recently, to Lead Researcher for GCP’s cassava work in Ghana. Now a well established cassava connoisseur who regularly rubs shoulders with the crème de la crème of the global crop science community, Elizabeth specialises in drought tolerance and disease resistance in the GCP-related aspects of her work, whilst also turning her hand to biofortification research for GCP sister CGIAR Challenge Programme, HarvestPlus.

… it [biotechnology] was a breakthrough which Elizabeth spearheaded…”

Up, up and away! How a helping hand has led Elizabeth & Co to new professional and research heights
Life aboard the GCP ship, Elizabeth reveals, has offered a wealth of professional opportunities, both on personal and institutional levels. GCP-funded infrastructure, such as weather stations and irrigation systems, has helped to boost yields and enhance the efficiency of CRI trials, she observes. Professional development for herself and her team, she says, has been multifold: “Through our GCP work, we were able to build a lab and kick-start marker-assisted breeding – that ignited the beginning of biotechnology activities in CRI,” Elizabeth asserts. It was a breakthrough which Elizabeth spearheaded, and which, happily, has since become run-of-the mill practice for the institute: “Now CRI scientists are regularly using molecular tools to do their work and are making cassava crosses on their own.” The positive domino effect of this change in tide cannot be underestimated: “Our once small biotechnology laboratory has evolved into a Centre of Excellence under the West Africa Agricultural Productivity Programme. Its first-class facilities, training courses and guiding hand in finding solutions have attracted countless visiting scientists, both from Ghana and internationally – this means that the subregion is also benefitting enormously.” The GCP’s Genotyping Support Service (GSS), Elizabeth affirms, has also proved an invaluable sidekick to these developments: “Through the GSS, our team learnt how to extract DNA as a first step, and later to re-enact all the activities that were initially done for us externally – data sequencing, interpretation and analysis for example – on a smaller scale in our own lab.” The collection and crunching of data has also become a breeze: “Thanks to GCP’s support, we have become a pace-setter for electronic data gathering using tablets, field notebooks and hand-held devices,” she adds.

….GCP gives you the keys to solving your own problems, and puts structures in place so that knowledge learnt abroad can be transferred and applied at home – it’s been an amazing journey!”

Ruth Prempeh, one of Elizabeth’s charges, collecting data for her GCP-funded PhD on cassava post-harvest physiological deterioration. Ruth is one of those whose work–family balance Elizabeth celebrates. Ruth has since submitted her thesis awaiting results. As you’ll hear in the podcast below, both of Ruth’s young children have each, er, sort of ‘attended’ two big GCP events!

People power: capacity building and work–life balance
Elizabeth lights up most when waxing lyrical about the leaps and bounds made by her many students and charges through the years, who – in reaping some of the benefits offered by GCP, such as access to improved genetic materials; forging links with like-minded colleagues near and far, and, critically, capacity building – have gone on to become established and often internationally recognised breeders or researchers, with the impacts of their work posting visible scores in the fight against global food insecurity. On the primordial role of capacity building, she says: “GCP gives you the keys to solving your own problems, and puts structures in place so that knowledge learnt abroad can be transferred and applied at home – it’s been an amazing journey!” Of her female students who’ve surmounted the work–family pendulum challenge, she says: “I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well. To see a talented woman researcher firmly established in her career and with her kids around her is thrilling.”

At IITA, Elizabeth continues to be an inspiration on work–life balance for women working on their PhDs, and more so for young women whose work is on cassava. In a male-dominated environment (global statistics report that women researchers are a meagre 30 percent), this inspiration is critical. .

No ‘I’ in team: tight-knit community a must for kick-starting real and sustainable solutions
As Elizabeth well knows, one swallow does not a summer make: as demonstrated by the GCP’s Communities of Practice (CoPs), she says, strength really does come in numbers: “The GCP Cassava CoP has brought unity amongst cassava breeders worldwide; it’s about really understanding and tackling cassava challenges together, and bringing solutions home.” Bolstering this unified spirit, Elizabeth continues, is the GCP’s Integrated Breeding Platform (IBP): “With the initial teething problems mainly behind us, IBP is now creating a global community and is an excellent way of managing limited resources, reducing duplication of efforts and allowing people to be more focused.” On helping scientists inundated with information to spot the wood from the trees, she says: “Over the years, lots of data have been generated, but you couldn’t find them! Now, thanks to IBP, you have sequencing information that you can tap into and utilise as and where you need to. It’s very laudable achievement!”

In the past, the assumption was always that ‘Africa can’t do this.’…GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner.”

Clearly, keeping the company of giants is not new for Elizabeth (right). This giant cassava tuber is from a 2010 CRI trial crossing improved CIAT material with CRI landraces (traditional farmer varieties. The trial was part of Bright Boakye Peprah’s postgraduate work. Bright has since completed his GCP-funded master’s degree on cassava breeding, and now a full time cassava breeder with CSIR–CRI. He is currently on study leave pursuing a PhD on cassava biofortification in South Africa. On the left is Joseph Adjebeng-Danquah, a GCP-funded PhD student whose work centres on cassava drought tolerance. Our best quote from Joseph: “It is important to move away from the all too common notion that cassava is an ‘anywhere, anyhow’ crop.”

Empowered and engaged: African cassava researchers reclaim the driving seat
The bedrock of GCP’s approach, Elizabeth suggests, is the facilitation of that magical much sought-after Holy Grail: self-empowerment. “When I first joined GCP,” she recalls, “I saw myself as somebody from a country programme being given a place at the table; my inputs were recognised and what I said would carry weight in decision-making.” It’s a switch she has seen gain traction at national and indeed regional levels: “In the past, the assumption was always that ‘Africa can’t do this.’ Now, people see that when given a chance to get round circumstances – as GCP has done for us through the provision of resources, motivation, encouragement and training – Africa can achieve so much!” Reflecting on the knock-on effect for African cassava researchers particularly, she concludes: “GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner.”

Paying it forward and sharing: Helping women, and thereby, communities
Armed with bundles of knowledge as she is, Elizabeth is a firm believer in paying it forward and sharing: “Building human capacity is my greatest joy,” she affirms, citing farmers, breeders, and a Ghanaian private-sector company as just a few of the fortunate beneficiaries of her expertise over recent years. And on sources of motivation, it is not the academic laurels or limelight but rather a broader vision of social justice which really drives her: “I see African communities where poverty and hunger are seemingly huge problems with no way out; I’m fortunate to be working on a crop whereby, if I put in enough effort, I can bring some solutions.” They are solutions which she hopes will be of lasting service to those closest to her heart: “My primary target group in my research is the less privileged, and women in particular have been my friends throughout. Rural families are held together by women, so if you are able to change their lot, you can make a real mark.”

We’re in a blessed and privileged era where cassava, an ancient and once orphan crop, is now receiving lots of attention… I encourage young scientists to come on board!”

Inspired, and inspiring: nurturing budding cassava converts, and seizing opportunities for impact
In terms of future horizons, Elizabeth – who after more than two decades of service at CRI is currently on leave of absence at IITA where she’s working on biofortification of cassava – hopes to thereby further advance her work on cassava biofortification, and perhaps later move into a management role, focusing on decision-making and leading agricultural research leaders with monitoring and evaluation specifically to “ensure that the right people are being equipped with skills and knowledge, and that those people are in turn teaching others.” She is also confident that any young, gifted researcher with an eye on the prize would be foolhardy to overlook what Elizabeth views as a golden opportunity for creating meaningful and lasting impacts: “We’re in a blessed and privileged era where cassava, an ancient and once orphan crop, is now receiving lots of attention. Every agricultural research lead we have in Africa is there to be seized – I encourage young scientists to come on board!” A clear and convincing clarion call to budding breeders or potential cassava converts if ever there was one…. who wants in, in this love-match where cassava and capacity building are truly two peas in a pod?

Like meets like in a fair match: Our cassava champion in a male-dominated environment, Elizabeth, meets her match in Farmer Beatrice who refused to take no for an answer, and beat Elizabeth hands down. Listen to this!

Cassava on the catwalk: Ghanaian ‘make-over’ for crop-science underdog

‘Made (up) in Ghana’

In the world of crop research as in the fashion industry, there are super-models, mere models, spectators and rank outsiders. Make no bones about it, trusty old cassava (Manihot esculenta) is a crop of very modest beginnings, but now finally strutting the research catwalk alongside the biggest and the best.

Elizabeth Parkes

An ancient crop thought to have been first domesticated in Latin America more than 10,000 years ago, it was exported by Portuguese slave traders from Brazil to Africa in the 16th century as a cheap source of carbohydrates. From there, today we travel half a millennium forward in time – and in space, on to Ghana – to catch up with the latest on cassava in the 21st century.

Come on a guided tour with Elizabeth Parkes (pictured), of Ghana’s Crops Research Institute (CRI, of the Council for Scientific and Industrial Research, CSIR), currently on leave of absence at the International Institute of Tropical Agriculture (IITA).

A hard-knock life, but still going strong
In keeping with its humble heritage, cassava is a crop which has long been reputed for being more than a little worn through at the elbows, commonly known as a “poor man’s crop” according to GCP cassava breeder and researcher, Elizabeth Parkes. However, much like a dishevelled duffle coat, what the crop lacks in shimmer and shine, it makes up for in sturdiness and dependability, rising to the occasion time and again by filling a critical gap – that of putting food in bellies – with a readiness and ease that its more sophisticated crop relatives have often struggled to keep up with. Elizabeth explains: “It has kept people alive over the years.” By the same token, the crop – now one of Africa’s most important staples – is fondly known in Ghana as bankye, meaning a ‘gift from the government’, thanks to its reliability and capacity to meet needs that other crops cannot. There is even a popular song in the country which pays homage to the crop as an indefatigable evergreen, conquering even the most willful and wily of weeds!

However, as cassava experts such as Elizabeth know only too well, behind this well-intentioned lyrical window dressing is the poignant story of a crop badly in need of a pressing pick-me-up. Hardy as it may seem on the surface, cassava is riddled with myriad problems of a political, physiological, environmental and socioeconomic nature, further compounded by the interactions between these. For starters, while it may be a timeless classic and a must-have item at the family table for a good part of Africa, à la mode it is not, or at least not for short-sighted policy-makers looking first and foremost to tighten their purse strings in straitened times, or for quick-fix, rapid-impact, silver-bullet solutions: “African governments don’t invest many resources in research. Money is so meager, and funds have mostly come from external agencies looking to develop major cereals such as rice. Cassava has been ignored and has suffered a handicap as a result – it’s more or less an orphan crop now,” Elizabeth laments. Besides having to bear witness to their favourite outfit being left on the funding shelf, cassava breeders such as Elizabeth are also faced with a hotchpotch of hurdles in the field: “In addition to factors such as pests and disease, cassava is a long-season and very labour-intensive crop. It can take a whole year before you can expect to reap any rewards, and if you don’t have a strong team who can step in at different points throughout the breeding process, you can often find unexpected results at the end of it, and then you have to start all over again,” Elizabeth reveals. Robust as it may be, then, cassava is no easy customer in the field: “After making crosses, you don’t have many seeds to move you to the next level, simply because with cassava, you just don’t get the numbers: some are not compatible, some are not flowering; it’s a real bottleneck that needs to be overcome,” she affirms.

No time for skirting the issue
And at the ready to flex their research muscles and rise to these considerable challenges was Elizabeth and her Ghanaian CRI team, who – with GCP support and in unison with colleagues from across Africa and the wider GCP cassava community – have been working flat out to put cassava firmly back on the research runway.

Thanks to funders such as GCP, who recognised that we couldn’t afford to turn a blind eye to the plight of this struggling crop, cassava has been given a voice…cassava is no longer just a poor man’s staple”

Elizabeth walks us through the team’s game plan: “GCP socioeconomist Glenn Hyman and team undertook a study to identify the best area in Ghana for supporting cassava flowering [Editor’s note: Glenn works at the International Center for Tropical Agriculture, CIAT]. Armed with that information, we have been applying grafting techniques, using hormones to induce flowering in Ghana and beyond.” The initiative is starting to bear fruit: “At the IITA–Nigeria Ubiaja site, for example, flowering is underway at factory-like efficiency – it’s a great asset. The soil has also greatly improved – we haven’t been able to pinpoint the exact cause yet, but what we’ve seen is that all cultivars there will now flower,” she reveals. Elizabeth’s team has been making steady progress in biotechnological techniques such as DNA extraction: thanks to work led by then GCP cassava comrade Martin Fregene (then with the International Center for Tropical Agriculture, CIAT, and now with the Donald Danforth Plant Science Center) and colleagues, focusing on the development of more reliable and robust simple sequence repeat (SSR) markers, Elizabeth was able to carry out genetic diversity diagnosis work on cassava, collecting germplasm from all over Ghana for the global GCP cassava reference set. [Editor’s note: A ‘reference set’ is a sub-sample of existing germplasm collections that facilitates and enables access to existing crop diversity for desired traits, such as drought tolerance or resistance to disease or pests]

Similar work was also conducted in Nigeria and Guatemala. So has this tremendous and tenacious teamwork proved strong enough to drag cassava out of the doldrums? Elizabeth certainly seems to think so: “Thanks to funders such as GCP, who recognised that we couldn’t afford to turn a blind eye to the plight of this struggling crop, cassava has been given a voice. Having worked together to understand the peculiarities of this crop, cassava is no longer just a poor man’s staple: beyond subsistence, it is becoming a crop of high starch quality, and of real use for industry, confectionary and even biofuels,” she enthuses.

Thankfully, it’s a most welcome change of tide that shows no sign of abating any time soon. Human capacity, Elizabeth says, is going from strength to strength, with three GCP-funded Ghanaian postgraduate students advancing well, two of them working on PhDs in what would normally be considered, according to Elizabeth, a ‘no-go area’ of cassava research – that is, cassava drought tolerance and post-harvest physiological deterioration (PPD), as well as bio-fortification. Efforts by the CRI team have resulted in the release of some 14–15 new drought-tolerant and PPD-resistant varieties in Ghana to date; all are anticipated to have a long shelf-life, and other varieties are also in the pipeline. Biofortified seeds are in the making, with a view to soon mainstream biofortification in the team’s breeding activities. The biofortification work is in collaboration with a sister CGIAR Challenge Programme, HarvestPlus.

The impact of our GCP-supported research on cassava has been remarkable. Above all, it’s been the community spirit which has moved things forward so effectively; in this respect, I think researchers working on other crops might want to borrow a leaf from the cassava book!”

Molecular masterstrokes, a leaf to lend despite cold shoulder, and a ‘challenge crop’ befitting Challenge Programmes
Forthcoming plans for Elizabeth and her cassava companions in Ghana include a GCP Cassava Challenge Initiative project which will seek to unearth new marker populations and materials which are drought-tolerant and resistant to cassava mosaic virus and cassava bacterial blight. The team has successfully introgressed materials from CIAT into their landraces, and the next step will be to gauge how best the new genes will react to these traits of interest. In terms of people power, the CRI biotechnology laboratory built with GCP support – and now a regionally accredited ‘Centre of Excellence’ – is a hive of activity for local and international scientists alike, and is consequently bolstering cassava research efforts in the wider subregion. “The impact of our GCP-supported research on cassava has been remarkable. Above all, it’s been the community spirit which has moved things forward so effectively; in this respect, I think researchers working on other crops might want to borrow a leaf from the cassava book!” Elizabeth ventures.

Reflecting back on the conspicuous cocktail of constraints which mired the crop in the early days of her research career – challenges which often resulted in a cold shoulder from many of her research peers over the years – Elizabeth recalls affectionately: “At first, people didn’t want to work on cassava since it’s truly a challenge crop: the genetics of cassava are really tricky. Colleagues from around the globe often asked me: ‘Why not go for a smooth crop which is friendly and easy?’” Her commitment, however, has been unfaltering throughout: “I’ve stuck with cassava because that’s my destiny! And now I see SNPs being developed, as well as numerous other resources. Once you clean something up it becomes more attractive, and my thanks go out to all those who’ve remained dedicated and helped us to achieve this.”

Thus, dusted down and ‘marked-up’ with a molecular make-over well underway, all evidence now suggests that this once old-hat subsistence crop is en route to becoming the next season’s big research hit, with shiny new cassava varieties soon to be released at a field station near you! Go, Ghana, go!

Having already heard the Integrated Breeding Platform (IBP) story on data from Arllet (spiced with a brief detour through Asia’s sun-splashed rice paddies), and on IBP’s Breeding Management System from Mark (where we perched on a corner on his Toulouse workbench of tools and data), we next set out to get an external narrative on IBP, and specifically, one from an IBP user. Well, we got more than we had bargained for from our African safari…

Yemi Olojede

Yemi Olojede (pictured) is much more than a standard IBP user. An agronomist by training with a couple of decades-plus experience, he not only works closely with breeders and other crop scientitsts, but is also a research coordinator and data manager. As you can imagine, this made for a rich and insightful conversation, ferrying us far beyond the frontiers of Yemi’s base in Nigeria, to the rest of West Africa, further out to Africa , and as far afield as Mexico, in his travels and travails with partners. We now bring to you some of this captivating conversation…

Yemi has been working for the last 23 years (since 1991) at Nigeria’s National Root Crops Research Institute (NRCRI) at Umudike in various capacities. After heading NRCRI’s Minor Root Crops Programme for 13 years, he was last year appointed Coordinator-in-Charge of the Cassava Research Programme.

But his involvement in agriculture goes much further back than NRCRI: Yemi says he “was born into farming”. His father, to whom he credits his love for agriculture, was a cocoa farmer. “I enjoy seeing things grow. When I see a field of crops …what a view!” Yemi declares.

Yemi is also the Crop Database Manager for NRCRI’s GCP-funded projects. He spent time at GCP headquarters in Mexico in February 2012 to sharpen his skills and provide user insights to the IBP team on the cassava database, on the then nascent Integrated Breeding Fieldbook, and on the tablet that GCP was considering for electronic field data collection and management.

To meet the farmers’ growing need for improved higher-yielding and stress-tolerant varieties, plant breeders are starting to incorporate molecular-breeding techniques to speed up conventional breeding.

Flashback to 2010: GCP was then piloting and testing small handheld devices for data collection. Field staff going through a training session for these under Yemi’s watchful eye (right).

But for this to happen effectively, cassava breeders require consistent and precise means to collect and upload research and breeding data, and secure facilities to upload that data into the requisite databases and share it with their peers. Eighty percent of farmers in Africa have less than a hectare of land – that’s roughly two football fields! With so little space, they need high-value crops that consistently provide them with viable yields, particularly during drought. For this reason, an increasing number of Nigerian farmers are adopting cassava. It is not as profitable as, say, wheat, but it has the advantage of being less risky. The Nigerian government is encouraging this change and is implementing a Cassava Transformation Agenda, which will improve cassava markets and value chains locally and create a sustainable export market. All this is designed to encourage farmers to grow more cassava.

Enter GCP’s Integrated Breeding Platform (IBP), which has been working closely with NRCRI and other national breeding programmes to develop the right informatic tools and support services for the job. The International Cassava Information System (ICASS), the Integrated Breeding Fieldbook and the tablet are all part of the solution, backed up by a variety of bioinformatic tools for data management, data analysis and breeding decision support that have been developed to meet the specific needs of the users.

I enjoy working with the team. They pay attention to what we as breeders want and are determined to resolve the issues we raise”

Fastfoward to 2012: Based on feedback, a larger electronic tablet was favoured over the smaller handheld device. Yemi (centre) takes field staff through the paces in tablet use.

The database and IB Fieldbook
“When I received the tablet I was excited! I had heard so much about it but only contributed ideas for its use through Skype and email,” Yemi remembers, echoing a sentiment that is frequently expressed by many partners who have been introduced to the device. “I experimented with the Integrated Breeding Fieldbook software focusing on pedigree management, trait ontology management, template design ‒ testing how easy it was to input data into the program and database.” Yemi noted a few problems with layout and data uploading and suggested a number of additional features. The IBP Team found these insights particularly useful and worked hard to implement them in time for the 2^nd Scientific Conference of the Global Cassava Partnership for the 21^st Century (GCP21 II), held in Kampala, Uganda, in June, 2012.

“I enjoy working with the team. They pay attention to what we as breeders want and are determined to resolve the issues we raise,” says Yemi. He believes the IB FieldBook and the tablet, on which it runs, will greatly benefit breeders all over the world, but particularly in Africa. “At the moment, our breeders and researchers have to write down their observations in a paper field book, take that book back to their computer, and enter the data into an Excel spreadsheet,” he notes. “We have to double-handle the data and this increases the possibility of mistakes, especially when we are transferring it to our computers. The IB Fieldbook will streamline this process, minimising the risk of making mistakes, as we enter our observations straight into the tablet, using specified terms and parameters, which will upload all the data to the shared central database when it’s connected to the internet.”

The whole room was wide-eyed and excited when they first saw the tablets”

Bringing the tablet to Africa
After his trip to Mexico, Yemi was concerned that some African breeders would be put off using the IB Fieldbook and accompanying electronic tablet because both require some experience with computers. “I found the tablet and the FieldBook quite easy to use because I’m relatively comfortable with computers,” says Yemi. “The program is very similar to MS-Excel, which many breeders are comfortable with, but I still thought it would be difficult to introduce it given that computer literacy across the continent is very uneven.”

Slim, portable and nearly invisible. A junior scientist at NRCRI Umudike tries out the tablet during the 2012 training session.

At the GCP21 II meeting in Uganda, Yemi helped the IBP team run IB Fieldbook workshops for plant breeders from developing countries, with an emphasis on data quality and sharing. “The whole room was wide-eyed and excited when they first saw the tablets. They initially had trouble using them and I thought it was going to be a very difficult workshop, but by the end they all felt confident enough to use them by themselves and were sad to have to give them back!”

They … go back to their research institutes and train their colleagues, who are more likely to listen and learn from them than from someone else.”

Providing extra support, cultivating trust
Yemi recounts that attendees were particularly pleased when they received a step-by-step ‘how-to’ manual to help them train other breeders in their institutes, with additional support to be provided by the IBP or Yemi’s team in Nigeria. “They were worried about post-training support,” says Yemi. “We told them if they had any challenges, they could call us and we would help them. I feel this extra support is a good thing for the future of this project, as it will build confidence in the people we teach. They can then go back to their research institutes and train their colleagues, who are more likely to listen and learn from them than from someone else.”

In developing nations, it is important that we share data, because we don’t all have the capacity to carry out molecular breeding at this time, and data sharing would facilitate the dissemination of the benefits to a wider group”

Sharing data to utilise molecular breeding
Yemi asserts that incorporating elements of molecular breeding has helped NRCRI a great deal. With conventional breeding, it would take six to 10 years to develop a variety before release, but with integrated breeding (conventional breeding that incorporates molecular breeding elements) it is possible to develop and release new varieties in three to four years ‒ half the time. Farmers would hence be getting new varieties of cassava that will yield 20‒30 percent more than the lines they are currently using in a much shorter time.

“In developing nations, it is important that we share data, because we don’t all have the capacity to carry out molecular breeding at this time, and data sharing would facilitate the dissemination of the benefits to a wider group,” says Yemi. “I enjoy helping people with this technology because I know how much it will make their job easier.”

Steaming rice bowl

What’s the latest from ‘GCP TV’? Plenty! With a world-favourite – rice – featuring high and hot on the menu.

Now serving our latest news, to tease your taste-buds with a tantalising and tingling potpourri of memorable cross-continental rice flavours, all captured on camera for our viewers…

Our brand-new series on YouTube serves up a healthy seven-course video feast inviting our viewers to sink their teeth into rice research at GCP.

First, we settle down for a tête-a-tête in the rice research kitchen with chef extraordinaire, Marie-Noëlle Ndjiondjop, Principal Investigator (PI) of GCP’s Rice Research Initiative in Africa, and Senior Molecular Scientist at Africa Rice Center. Target countries are Burkina Faso, Mali and Nigeria.

Marie-Noëlle Ndjiondjop

Starters, palate and pocket
Marie-Noëlle opens the feast with a short but succulent starter, as she explains succinctly in 30 seconds just how rice is becoming a staple in Africa. In the second course, Marie-Noëlle chews over the questions concerning combatting constraints and boosting capacity in rice research in Africa.

The third course is pleasing to the eye, the palate and the pocket! Marie-Noëlle truly sells us the benefits of molecular breeding, as she extolls the virtues of the “beauty of the marker”. Why should you use molecular tools? They’ll save you time and money!

Rice as beautiful as the markers Marie-Noëlle uses in molecular breeding

Wherefore art thou, capacity building in rice research in Africa?
The Shakespearean language alludes to the why of capacity building in Africa, as does video episode number four, which also tackles the what of this fourth dish in our banquet. Course number five offers the viewer a light look at how capacity building in Africa is carried out.

In the 6^th course, Marie-Noëlle takes us out of this world and into MARS: she teaches us that ‘two are better than three’, as she explains how the novel bi-parental marker-assisted recurrent selection (MARS) method is proving effective when it comes to duelling with drought, the tricky three-headed monster comprising physiological, genetic and environmental components.

Blooming rice in the field

Of stars and scoundrels
The 7^th and final course offers us a riveting tale of heroes and villains, that is, many heroes and a single villain! Our rice raconteuse, Marie-Noëlle, praises the power of the team, as a crew from cross-continental countries come together, carefully characterise their combatant (drought), before striking with environment-specific drought-tolerant varieties! AfricaRice’s project partners are Burkina Faso’s Institut de l’environnement et de recherches agricoles (INERA); Mali’s Institut d’économie rurale (IER); and Nigeria’s National Cereals Research Institute (NCRI). Collaborators are France’s Centre de coopération internationale en recherche agronomique (CIRAD); the International Center for Tropical Agriculture (CIAT); and the International Rice Research Institute (IRRI).

We hope these tasty teasers are enough to whet your appetite – you can savour each of the courses individually à la carte, or, for those with a daring desire to try the ‘all you can eat’ buffet for true rice gourmets, all seven courses are presented as a single serving on our YouTube channel.

Tastes from Asia
To further please your palate with our rice bowl of delights, our next stop is Asia. We are pleased to offer you the Asian flavour through a peek into the world of molecular rice breeding in the Mekong region. Our connection to this project is through a GCP-funded capacity-building project entitled A Community of Practice for strengthening rice breeding programmes by using genotyping building strategy and improving phenotyping capacity for biotic and abiotic stresses in the Mekong region led by PI Jonaliza Lanceras-Siangliw, of the National Center for Genetic Engineering and Biotechnology (BIOTEC), Thailand (see project poster, and slides on a related drough t-tolerance project led by Boonrat Jongdee). BIOTEC’s partners in the Mekong rice breeding CoP are the Cambodian Agricultural Research and Development Institute (CARDI); LAO PDR’s National Agricultural and Forestry Research Institute (NAFRI); Myanmar’s Department of Agricultural Research (DAR); and Thailand’s Kasetsart University and Ubon Ratchathani University). The video also features former GCP PI, Theerayut Toojinda (BIOTEC) whose project was similarly entitled The ‘Community of Practices’ concept applied to rice production in the Mekong region: Quick conversion of popular rice varieties with emphasis on drought, salinity and grain quality improvement.

A new breed of Workbench – Introducing the Breeding Management System

Crop breeding, Crop information and data management, Integrated Breeding Platform 2 Responses »

Mark Sawkins

Mark the man in the middle, and of the markers…

Today, we talk to Mark Sawkins (pictured), the ‘middleware’ man in our Integrated Breeding Platform (IBP) so to speak, seeing as he is the human ‘interface’ between crop breeders on the one hand, and the developers of our Integrated Breeding Platform (IBP) on the other hand. Mark is the ‘bridge’ that connects IBP users and IBP developers – a special position which gives him a privileged and fascinating perspective on both sides of the coin, with a dash of public–private sector pragmatic partnership thrown in too. Here’s more on Mark, in this dispatch from and on his special perch on the bench…

Bridge to bench, abuzz on BMS: A ‘tinker’ at Toulouse…
Mark Sawkins is always busy tinkering away on his Workbench at his base in Toulouse in southern France. It’s not your traditional wooden workbench, covered in sawdust, soil or splattering of paint. Nor is it one carpeted in documents lit by the warm glow of a computer monitor. In fact, the workbench Mark is working on is virtual, having no physical form and residing solely online, or on a user’s computer, once downloaded.

Known as the Breeding Management System (BMS) the Workbench, comprising software tools linked to a database for access to pedigree, phenotypic and genotypic data, has been developed by GCP’s Integrated Breeding Platform. The BMS has what a crop breeder would require to conduct an analysis of phenotypic and genotypic data generated as part of a crop-breeding or evaluation experiment, covering a broad spectrum of needs from conventional breeding to advanced molecular breeding applications. Version 2 of the Breeding Management System was released just last month.

… it [BMS] will be of most help to breeders both in the public and private sector in Africa and Asia who, up to now, have had little or no access to tools and data to allow them to shift gears in their breeding programme…The BMS has a lot of tools and all the foundational data necessary for a breeder’s routine day-to-day activities…The BMS is also anticipated to have enormous positive impact on food security in developing countries in the years ahead, enabling crop breeders to evaluate their progenies using the most sophisticated statistical methods available”

A hands-on BMS orientation workshop underway for breeders in Africa, held in Ethiopia in July 2013 under the auspices of the GCP-funded cassava breeding community of practice. Standing, Yemi Olojode, of Nigeria’s National Root Crops Research Institute (NRCRI), Umidike, who was one of the trainers.

Previously known as the Integrated Breeding Workflow System (IBWS), the BMS incorporates both statistical analysis tools and decision-support tools. The tools are assembled in a way that data can flow seamlessly from one application to the next in tandem with the various stages of the crop-breeding process. It allows the breeder to accurately collect, securely store and efficiently analyse and synthesise their data on a local private database, and also share, or compare, their data with other breeders via a central public crop database.

“The BMS has a lot of tools and all the foundational data necessary for a breeder’s routine day-to-day activities,” explains Mark, a plant geneticist who joined IBP in 2011. “Any breeder can use it, but it will be of most help to breeders both in the public and private sector in Africa and Asia who, up to now, have had little or no access to tools and data to allow them to shift gears in their breeding programme, particularly in adopting modern breeding practices, including the use of molecular markers.”

The BMS is also anticipated to have enormous positive impact on food security in developing countries in the years ahead, enabling crop breeders to evaluate their progenies using the most sophisticated statistical methods available, and make selections on which lines to advance to the next phase of development in the progression towards more productive and resilient crop varieties.

Phenotyping and field trials are becoming the most expensive part of the breeding process… The biggest hurdle in the public sector in the past was the massive investment required to set up genotyping laboratory facilities… outsourcing, we believe, will help convince breeders to consider integrating molecular techniques into their breeding programmes”

Why integrated breeding?
For almost 30 years, the private sector has been implementing molecular-breeding approaches in developing more productive and resilient crops. These approaches allow breeders to select for plant characteristics (traits) early in the breeding process and then test whether a plant has the targeted trait, which they cannot visually identify.

“Phenotyping and field trials are becoming the most expensive part of the breeding process,” says Mark. “Using molecular markers is a way to reduce the investment in that process. By using markers, early in the development of a given crop line, you can reduce the number of plants you need to grow and test, reducing the time and cost associated with field trials.”

Mark hopes that the Workbench will in time enable breeders, in under-resourced public breeding institutes to access some of the leading molecular-marker databases, and make use of the markers therein for the desired traits they are breeding for, along with technical support from molecular breeders to guide them in making their breeding decisions.

“The biggest hurdle in the public sector in the past was the massive investment required to set up genotyping laboratory facilities,” explains Mark “but now there are plenty of professional service providers that people can send their samples to and get back good results at a very reasonable cost. This time- and cost-saving reality of outsourcing, we believe, will help convince breeders to consider integrating molecular techniques into their breeding programmes.”

We are currently conducting a three-year course to train scientists from national programmes in West and Central Africa, East and Southern Africa and South and Southeast Asia, who we hope will promote and support the adoption of modern breeding in their institutes and countries.”

Running with champions
Mark knows that giving breeders the tools and means to integrate molecular breeding into their programmes is one thing. To actually have them adopt them is another. But he has a plan.

In keeping with the core mission of GCP, which is to build sustainable capacity in developing-country breeding programmes, Mark proposes to recruit and train selected breeders in molecular-breeding techniques and set them up as champions and advocates for their particular crop or region.

Marker implementation methods can be varied but the tools required need to help the breeder make a quick informed decision on what to take forward to the next generation: What plants need to be crossed? Which plants should be kept and which ones discarded? The decision-support tools provided by the IB Workbench will help the breeder make these decisions.

“We are currently conducting a three-year course to train scientists from national programmes in West and Central Africa, East and Southern Africa and South and Southeast Asia, who we hope will promote and support the adoption of modern breeding in their institutes and countries,” Mark enthusiastically explains. The three-year training programme is known as the Integrated Breeding Multiyear Course (IB–MYC). Mark continues, “We believe that people will be more willing to listen to someone who is right there on the ground, whom they know and trust and can easily get in contact with if they need help.”

While the champions concept is still in its infancy, Mark believes it has real merit but must overcome two major barriers – time and confidence. “Identifying the champions won’t be hard,” he observes, “What will be hard is getting them to add this extra task to their already busy agenda. It will require buy-in from management at the institutional level to enable the champions to carry out their mission. It will also be individually hard for each champion, who will only be successful when they have the confidence in their own integrated breeding and extension skills. This confidence would be the thing that would really help sell the message.”

Engaging the private sector
Mark oversees the design, testing and deployment of the system that underpins the BMS, ensuring that both the system and the tools embedded in it are easy to use and meet the needs and expectations of the breeders. However, he and his team have had some trouble getting feedback on the system from the breeders it is intended for, due to their inexperience with such tools and systems. That is why he has called on his private-sector contacts, developed when he was at Syngenta where he worked for five years prior to his current assignment.

“We hope to show them what we’ve been doing in IBP with the Workbench, and hopefully get some private-sector buy-in and see how they can help us – not in developing tools, but with feedback on functionality and usability of the tools we are developing,” he explains. “We don’t have a core set of breeders who are routinely using markers in their breeding programme amongst the partners we are working with on the IBP project. So we are tapping into the private sector which has teams of molecular breeders who are more familiar with the types of breeding workflows and tools we are developing. We’re hoping that we can take advantage of their knowledge and experience to get some really useful feedback, which we will use to improve the usability and effectiveness of our tools.”

To maximise adoption and use, GCP has been actively engaged in extensive capacity building, and this will be reinforced with a comprehensive awareness-creation and communication effort immediately before and after a projected mid-year release of a newer BMS version incorporating the all-essential user feedback. The impact of the analytical pipeline in developing countries will be particularly enhanced with the availability of efficient user support services, which Mark will be overseeing.

Cassava’s gain, and surgery’s ‘pain’: Career crossings and causerie with Chiedozie Egesi

Chiedozie Egesi

Despite the social injustice around me, I always thought there was opportunity to improve people’s lives…GCP helped us to build an image for ourselves in Nigeria and in Africa, and this created a confidence in other global actors, who, on seeing our ability to deliver results, are choosing to invest in us.”
– Chiedozie Egesi, a would-have-been surgeon who switched sides to biology and crop genetics, and who got acquainted with GCP through the Internet.

Backdrop: A booming economy and a wealth of natural resources may be among some of the common preconceptions of the average Jane and Joe regarding Africa’s most populous nation. Lamentably, however, Nigeria, like numerous robust economies worldwide, is still finding its feet in addressing severe inequality and ensuring that the nation’s wealth also flows to the poorest and most marginalised communities.

It’s a problem Chiedozie Egesi (pictured above), a molecular plant breeder at Nigeria’s National Root Crops Research Institute (NRCRI), understands well: “Nigeria is an oil-producing country, but you still see grinding poverty in some cases. Coming from a small town in the Southeast of the country, I grew up in an environment where you see people who are struggling, weak from disease, poor, and with no opportunities to send their children to school,” he reveals. The poverty challenge, he explains, hits smallholder farmers particularly hard: “Urban ‘development’ caught up with them in the end: some of them don’t even have access to the land that they inherited, so they’re forced to farm along the street.”

Maturing cassava fruits.

Food first! A man with a mission and fire in his belly, determined to make a difference
For this gifted and socially conscious young man, however, the seemingly bleak picture only served to ignite a fierce determination and motivation to act: “Despite the social injustice around me, I always thought there was opportunity to improve people’s lives.” And thus, galvanised by the plight of the Nigerian smallholder, plans for a career in medical surgery were promptly shelved, and traded for biological sciences and a PhD in crop genetics, a course he interspersed with training stints at USA’s Cornell University and the University of Washington, Seattle, along the way, before returning to the motherland to accept a job as head of the cassava breeding team, and – following a promotion in 2010 – Assistant Director of the Biotechnology Department, at NRCRI.

As evident from the burgeoning treasure chest of research gems to his name, it was a professional detour which paid off, and which continues to bear fruit today.

Making a marked difference, cultivating new partnerships, and looking beyond subsistence
In 2010, work by Chiedozie and his NRCRI team resulted in the official release of Africa’s first molecular-bred cassava variety which was both disease-resistant and highly nutritious – an act they followed in 2012 with the release of a high-starch molecular-bred variety. The team’s astute navigation of molecular markers resulted in breeding Latin American cassava varieties resistant to cassava mosaic disease (CMD), leading to the release of CMD-resistant cassava varieties in the African continent for the first time. Genetic maps intended to enhance breeding accuracy for cassava – the first of their kind for the crop in Africa – have been produced, and quantitative trait loci (QTLs) for cassava breeding are in the making. In 2011, the team, together with their partners at the International Institute of Tropical Agriculture (IITA) and HarvestPlus (a CGIAR Challenge Programme), released three pro-vitamin A-rich varieties of cassava, which hold the potential to provide children under five and women of reproductive age with up to 25 percent of their daily vitamin A allowance – a figure Chiedozie and his team are now ambitiously striving to increase to 50 percent.

These new and improved varieties – all generated as a direct or indirect result of his engagement in GCP projects – are, Chiedozie says, worth their weight in gold: “Through these materials, people’s livelihoods can be improved. The food people grow should be nutritious, resistant and high-yielding enough to allow them sell some of it and make money for other things in life, such as building a house, getting a motorbike, or sending their kids to school.”

Prior to my GCP work, I was more or less a plant breeder, and a conventional one at that. Whilst I’d been exposed to molecular tools during my early work on yam and other crops, I was not applying them in my work back then…GCP was not only there to provide technology but also to guide you in how to operate that technology… Now all our staff understand what is meant by good breeding, data analysis or applying genotypic data. My whole team benefitted.”

A chance ‘meeting’, with momentous manifold connections
Having first stumbled across the GCP website by chance when casually surfing the internet one day in a cyber café back in 2004, Chiedozie’s attention was caught by an announcement for a plant breeders’ training course in South Africa, an opportunity which he applied for on the off chance…and for which, hey presto!, he was accepted! Thus, his GCP ‘adventure’ began!

Promptly revealing an exceptional craftsmanship for all things cassava, Chiedozie soon became engaged in subsequent opportunities, including a one-year GCP fellowship at the International Centre for Tropical Agriculture (CIAT) in Colombia, a number of GCP Capacity building à la carte-facilitated projects, and, more recently, a major role as a Principal Investigator in the GCP Cassava Research Initiative (RI), teaming up with NRCRI colleague and Cassava RI Product Delivery Coordinator, Emmanuel Okogbenin. The Cassava RI is where Chiedozie’s energies are primarily invested at present, with improving and deploying markers for biotic stresses in cassava being the name of the game.

The significance of his GCP engagements was, Chiedozie affirms, momentous: “Prior to my GCP work, I was more or less a plant breeder, and a conventional one at that. Whilst I’d been exposed to molecular tools during my early work on yam and other crops, I was not applying them in my work back then.”

Collaboration in a GCP-funded project with CIAT led to the development of a new laboratory space for NRCRI, bolstered by support for basic materials as well as training. “GCP was not only there to provide technology but also to guide you in how to operate that technology,” Chiedozie comments. (For more on how it all began, see At home and to go and Molecular bonds in pp 26–29 in this e-book)

GCP’s Integrated Breeding Platform (IBP), he says, has played a vital role in this regard: “By opening the door to training, generation of data, analysis of data, and by giving support in making decisions, GCP’s IBP serves as a one-stop shop for cassava breeding.” It’s a sentiment shared by his NRCRI colleagues, he says: “GCP is providing a comprehensive full-package deal. Besides myself, several colleagues have been trained at NRCRI. Now all our staff understand what is meant by good breeding, data analysis or applying genotypic data. My whole team benefitted.”

A real deal-breaker is the facilitation of self-empowerment amongst national programmes, and the new avenues unfolding for enhanced collaboration at the local, national and regional level…What we’re seeing is a paradigm shift. In the past there was a general belief that this kind of advanced molecular science was only feasible in the hands of CGIAR Centres or developed-country research institutes – the developing-country programmes were never taken seriously. When the GCP opportunity to change this came up we seized it, and now the developing-country programmes have the boldness and capacity to do molecular breeding and accurate phenotyping for themselves.”

Growth in numbers, capital, capacity, collaboration, reach and impact
Strength in numbers, Chiedozie says, is a vital lifeline for cassava, a crop which has suffered years of financial neglect. As such, a real deal-breaker in Chiedozie’s eyes is the facilitation of self-empowerment amongst national programmes, and the new avenues unfolding, thanks to his involvement in the GCP cassava breeding Community of Practice (CoP), for enhanced collaboration at the local, national and regional level: “We now have a network of cassava breeders that you can count on and relate with in different countries. This has really widened our horizons and also made work more visible,” he offers, citing effective links formed with Ghana, Sierra Leone, Liberia, Mozambique, Malawi and Côte d’Ivoire, amongst several other cassava-breeding neighbours near and far.

Cassava leaf

The achievements amongst this mushrooming community are, he stresses, unprecedented: “Participation in the CoP means many countries can now create their own hybrids and carry out their own selection, which they could not do before,” he affirms.

And it’s a milestone Chiedozie and colleagues are justifiably proud of: “What we’re seeing is a paradigm shift. In the past there was a general belief that this kind of advanced molecular science was only feasible in the hands of CGIAR Centres or developed-country research institutes – the developing-country programmes were never taken seriously. When the GCP opportunity to change this came up we seized it, and now the developing-country programmes have the boldness and capacity to do molecular breeding and accurate phenotyping for themselves,” Chiedozie confirms.

GCP helped us to build an image for ourselves in Nigeria and in Africa, and this created a confidence in other global actors, who, on seeing our ability to deliver results, are choosing to invest in us.”

Building on success, going from strength to strength as the sands shift

With internal capacity now blossoming of its own accord – in no small measure due to the leading role played by NRCRI in the sensitisation of cassava plant breeders throughout Nigeria and beyond – the sands are certainly shifting: “GCP helped us to build an image for ourselves in Nigeria and in Africa, and this created a confidence in other global actors, who, on seeing our ability to deliver results, are choosing to invest in us.”

And the beauty of it, Chiedozie continues, is that the cassava crew is going from strength to strength: “Nigeria is seen as a really strong cassava-breeding team, not only within Africa but also globally. And we have not yet realised all the benefits and potential – these are still unfolding,” he enthuses.

Also yet to unfold are Chiedozie’s upcoming professional plans, which, he reveals, will soon see him engaging with the USA’s Cornell University, the Bill & Melinda Gates Foundation, the International Institute of Tropical Agriculture (IITA) and Uganda’s National Crop Resources Research Institute (NaCRRI) in an initiative which, through its focus on genomic selection in cassava breeding, promises to be, Chiedozie reveals, “at the frontier of cutting-edge technology.” Genomic selection for this initiative is already underway.

Readers intrigued by this tantalising taster of what to expect in Chiedozie’s next professional chapter are encouraged to watch this space over the coming years…Judging by his remarkable research record to date, we feel confident that future installments will not disappoint!

Meantime, here’s Chiedozie’s presentation at the GCP General Research Meeting in September 2013. We are also working on videos of Chiedozie and his work. Yet more reason to watch this space!

A bout with drought and disease: Beans that beat the heat and odds in Zimbabwe

Africa, Beans, Capacity building, Genomics, Legumes 2 Responses »

Feb 282013

Drought stalks, some die
Despite the widespread cultivation of beans in Africa, yields are low, stagnating at between 20 and 30 percent of their potential. Drought brought about by climate change is the main culprit, afflicting 70 percent of Africa’s major bean-producing regions in Southern and Eastern Africa.

Today we turn the spotlight on Zimbabwe, where drought is a serious and recurrent problem. Crop failure is common at altitudes below 800 meters, and livestock death from shortage of fodder and water are all too common. In recent history, nearly every year is a drought year in these low-lying regions frequently plagued by delayed rains, as well as by intermittent and terminal drought.

The ‘battleground’ and ‘blend’
Zimbabwe is divided into five Natural Regions or agroecological zones. More than 70 percent of smallholder farmers live in Natural Region 3, 4 and 5, which jointly account for 65 percent of Zimbabwe’s total land area (293,000 km²). It is also here that the searing dual forces of drought and heat combine to ‘sizzle’ and whittle bean production.

The rains are insufficient for staple foods such as maize, and some of their complementary legumes such as groundnuts. In some areas where temperatures do not soar too high (less than 30^oC), beans blend perfectly into the reduced rainfall regime that reigns during the growing season.

A deeper dig: the root of the matter

Godwill Makunde

Research from Phase I of the Tropical Legumes I (TLI) project under GCP’s Legume Research Initiative showed that deep rooting is one of the ways to confer drought tolerance in common beans. High plant biomass at pod-filling stage also confers drought tolerance. “These important findings from TLI refined our breeding objectives, as we now focus on developing varieties combining deep roots and high plant biomass,” reveals Godwill Makunde (pictured), a bean breeder at Zimbabwe’s Crop Breeding Institute (CBI), which falls under the under the country’s Department of Research & Specialist Services. Zimbabwe is one the four target countries in Eastern and Southern Africa for GCP’s bean research (the other three being Ethiopia, Kenya and Malawi).

From America to Africa…the heat is on, so is the battle…

The battle is on to beat the heat: through the project, CBI received 202 Mesoamerican and Andean bean breeding lines from the reference set collection held by the International Center for Tropical Agriculture (CIAT, by its Spanish acronym). A ‘reference set’ is a sub-sample of existing germplasm collections that facilitates and enables access to existing crop diversity for desired traits, such as drought tolerance or resistance to disease or pests. The Institute also embarked on bringing in more techniques to breed for heat tolerance.

Drought, pests and disease
“We embraced mutation breeding in collaboration with the International Atomic Energy Agency, and we primarily look for heat tolerance in small-seeded beans,” says Kennedy Simango (pictured right and below), a plant breeder at CBI. “Preliminary results suggested that just like drought, the reproductive stages of common bean are when the crop is most sensitive to heat. Flower- and pod-drop are common. Yield components and yields are severely reduced. In addition, we also focus on developing pest- and disease-resistant varieties.”

Kennedy Simango at work a the Crop Breeding Institute.

The CBI project’s primary diseases and pests of focus are angular leaf spot (ALS), common bacterial blight (CBB), rust and bean stem maggot, and aphids. “This came from our realisation that drought co-exists with heat, diseases and pests,” Kennedy adds. “So, a variety combining drought, heat, disease and pest tolerance all together would increase common bean productivity under harsh environments or drought-prone areas.”

At first glance, piling up all these vital survival traits may appear insurmountable, but it is all feasible, thanks to advances in plant science. “Breeding methods are changing rapidly, and it is vital that we keep up with the technology,” says Kennedy.

The CBI team is using molecular breeding to identify drought-tolerant parents, and then cross them into preferred bean varieties to confer to the ‘offspring’ the best of both worlds – drought tolerance and market appeal.

All-round capacity and competence
GCP’s support does not stop at enabling access to breeding lines alone, or introduction to molecular breeding. “We got a lyophiliser, which is specialised equipment that enables us to extract DNA and send it for genotyping,” says Kennedy. “From the genotyping exercise, we hope to be able to trace the relationships among breeding lines so that we design better crossing programmes, and thereby maximise the diversity of our breeding lines. In addition, we hope to select recombinants carrying desirable genes in a short period of time, and at times without even needing to test them in the target environment.” GCP assists with genotyping through its Genotyping Support Service offered through the Integrated Breeding Platform.

For phenotyping, CBI has benefitted from a mobile weather station, a SPAD meter (for measuring chlorophyll content), a leaf porometer (for measuring leaf stomatal conductance) and water-marks (probes for measuring soil moisture).

Human resources have not been forgotten either. Godwill Makunde, a CBI bean breeder, is studying for a TLII-funded PhD in Plant Breeding at the University of the Free State, South Africa. A group of four scientists (Godwill and Kenedy, plus Charles Mutimaamba, and Munyaradzi Mativavarira) are in GCP’s three-year Integrated Breeding Multi-Year Course (IB–MYC). The curriculum includes design of experiments, data collection, analysis and interpretation, molecular breeding and data management techniques. In addition, GCP also trains research technicians. For CBI, Clever Zvarova, Anthony Kaseke, Mudzamiri and Chikambure have attended this training. Their course also includes phenotyping protocols (data collection and use of electronic tablets in designing field-books). To date, CBI has received five tablets for digital data collection , of which two are outstanding.

Godwill doing what he does best: bean breeding.

Bringing it all together, and on to farms
But how relevant are all these breeder-focused R&D efforts to the farmer? Let’s review this in proper context: in the words of Mr Denis Mwashita, a small-scale farmer at the Chinyika Resettlement Scheme in Bingaguru, Zimbabwe, “Beans have always carried disease, but from the little we harvest and eat, we and our children have developed stomachs.”

“What Mr Mwashita means is that despite the meagre harvests, farm families fare better in terms of health and nutrition for having grown beans,” explains Godwill.

With this solid all-round support in science, working partnerships, skills and infrastructure, the CBI bean team is well-geared to breed beans that beat both heat and disease, thereby boosting yields, while also meeting farmer and market needs. Trials are currently underway to select lines that match these critical needs which are the clincher for food security.

“The Zimbabwe market is used to the sugar type, which is however susceptible to drought. We hope to popularise other more drought-tolerant types,” says Kennedy. “We plan to selected a few lines in the coming season and test them with farmers prior to their release. Our goal is to have at the very least one variety released to farmers by mid-2013.”

A noble goal indeed, and we wish our Zimbabwe bean team well in their efforts to improve local food security.

Science in her blood – Born into botany, bloomed into biochemistry and molecular biology, and now in applied science

Asia, Capacity building, Genetics, Genomics, Researchers, Rice, Women in science 1 Response »

Dec 212012

I’ve always enjoyed my job, particularly teaching students and young researchers, but this project has made me think about how I can do more practical science.” – Zeba Seraj, Biochemistry and Molecular Biology Professor, University of Dhaka, Bangladesh

Zeba Seraj

Growing up with a botanist as a father, Zeba Seraj was nurtured to look at plants in a scientific light. But at one stage in her life, she took a different fork on the road: she was more interested in rat livers and cow eyes, before becoming a ‘late bloomer’ in applied science and molecular plant breeding, which is her current niche.

Taking that fork: rats seduced, cows made eyes, but both lost…
Having completed her Undergraduate and Master’s in Biochemistry at the University of Dhaka, Bangladesh, during the 70s and 80s, she moved to Scotland for a PhD at the University of Glasgow. After being persuaded that molecular biology and recombinant DNA technology were not likely to be too different in animals and plants, she focused on the separation of nuclear proteins involved in post-transcriptional processing in the rat liver system.

“I then went on to work as a postdoc at the University of Liverpool, UK, for 18 months, where I worked on a bovine retina cDNA [complementary DNA] library,” Zeba recalls. “I was exposed to a number of recombinant DNA techniques and was pleasantly surprised to find DNA much easier to work with compared to proteins! I enjoyed it, but when I returned to the Bangladesh, there was no work in that field, so I turned to plants.”

The rise of rice, propelled by ‘Petrra’ project and petri dish
Back at her old University, one of Zeba’s first projects was working on salt tolerance in rice which allowed her to set up plant tissue culture facilities and establish a modest molecular biology laboratory. Zeba thereafter worked with the International Rice Research Institute (IRRI) and the Bangladesh Rice Research Institute (BRRI) on the Petrra project (poverty elimination through rice research assistance). The project was funded by the Department for International Development, UK. Meanwhile, she also spent a couple of months in the laboratory of the illustrious Dr John Bennett at IRRI, learning the latest technology in DNA markers and polymerase chain reaction (PCR) technology. This inital work would, in a way, lead her to GCP.

Meeting GCP, and banking on potential
Zeba joined the GCP community in 2005, working on the rice Saltol (salt tolerance) project. She was a focal collaborator in Bangladesh for this IRRI-led project that aimed to revitalise marginal ricelands by discovering and breeding into popular rice varieties ‘survival’ genes to enable rice to not only survive but also thrive on saline or phosphorus-poor soils.

“We were introduced to the project through the Principal Investigator, Abdel Ismail,” recalls Zeba. “Our lab was not very modern, but we did have all the facilities to do marker work, as well as a firm grasp on the theory, so IRRI and GCP must have seen potential in us.”

…doing the research helped me understand the practical application better… It was a real eye-opener.”

Transiting from theory to practice
After 15 years of working as an associate professor and professor at the University of Dhaka (DU), mainly nurturing young biochemists, Zeba was re-energised by the thought of working on such a practical project that would have a direct impact on her country’s food security, and on its farmers’ livelihoods.

In the background, genotyping in progress at the Department of Biochemistry and Molecular Biology, University of Dhaka. In thef oreground, student– supervisor consultations. Pictured (left to right) are: Zeba I Seraj, Roman, Adnan, Sarwar, Debashis,Rabin, Dost, Mishu, Shamim and Rejbana.

Nearly one million hectares along the Bangladesh coast are affected by varying degrees of salinity which has severely limited the introduction of modern high-yielding rice varieties, as few of these are saline-tolerant. Given Bangladesh’s high population, farmers need as bountiful yields as possible, and minimum risk of failure.

“After reading and teaching theory for so long, it was really exciting to actually put it into practice and work towards a practical outcome,” says Zeba.

“Actually doing the research helped me understand the practical application better too. It was a real eye-opener.”

Using molecular markers allowed us to at least halve the time it would take to release stress-tolerant rice.”

Gaining time: the ‘miracles’ and ‘magic’ of molecular makers
Zeba’s lab was responsible for the molecular evaluation and selection of rice lines bred by BRRI for insertion of the genomic region containing Saltol (discovered to confer salt toleranceby the previous IRRI-led GCP-funded project).

Md Sazzadur Rahman of BRRI assesses progress on a salt-tolerant rice variety in the field.

“We collected leaf samples from the BRRI-bred lines which were a combination of popular rice landraces and a Saltol donor.” explains Zeba ‘Landraces’ is ‘breeder-speak’ for varieties grown by, and popular with, farmers, but not necessarily improved by selective scientific breeding. Zeba continues, “We then used molecular markers which would indicate the presence of the Saltol genomic region.”

“The information we gathered guided the breeders at BRRI to select rice plants with the Saltol region. Selected plants were then further analysed with markers, to maximise the presence of popular alleles,” she adds. Allele is one of two, or more, forms of a gene – the alternative form of a gene responsible for a trait producing different effects.

“Using molecular markers allowed us to at least halve the time it would take to release stress-tolerant rice,” Zeba reveals.

I will be the happiest person on earth the day they release the new lines, knowing that I’d helped to make a difference.”

Seven years on, what next?
Zeba is grateful that she and her lab were active partners in GCP projects for seven consecutive years: first in the IRRI-led project in 2005 to 2009, then in a follow-up supplementary capacity-building DU-led project from 2010 to 2011, for which Zeba was the Principal Investigator.

“I don’t think we could have done the work without the various GCP networks. Several times in the project we would lag behind and they’d offer us support to get us back on track,” says Zeba. “They also instilled in us the importance of proper data management, and we have now implemented their system to collect, store and report data for all of our projects. We also now have all the equipment and processes in place, meaning that we’re now able to accommodate similar projects, now and into the future.”

Personally Zeba feels the project has given her a new direction in her career that she’s keen to further explore. “I’ve always enjoyed my job, particularly teaching students and young researchers, but this project has made me think about how I can do more practical science,” confides Zeba.

As for the Saltol project, she is keeping a close eye on the application waiting for the news of high-yield salt-tolerant lines becoming accessible to all Bangladeshi rice farmers.

“I will be the happiest person on earth the day they release the new lines, knowing that I’d helped to make a difference.”

Of magic beans and giant beanstalks: A legume fairy tale coming true in Ethiopia

Nov 292012

By Gillian Summers

The TLI project lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.” – Asrat Asfaw Amele, Southern Agricultural Research Institute, Ethiopia

Many a tale about Ethiopia will regale the reader with details of its contrasting landscape, numerous rivers, searing regional temperatures, the multicultural makeup of its society, its world-famous, unbeatable long-distance and high-altitude runners, its rich history and culture; a sweet producer of honey, the home of coffee, and origin of all mankind…

Seeing red… but no blood
…I found a land of incurably hospitable and kind people, proud of their country and culture; infectiously good music, incredibly strong coffee, where they love both bloody raw meat and protein-rich red beans, dubbed ‘bloodless meat’ in this part of the world.

Cool early morning departure

Out & about
My first real taste of Ethiopia was out in the countryside where I visited the work of GCP’s Tropical Legumes I (TLI) project in the field, on a trip to the bean fields at the Southern Agricultural Research Institute’s (SARI) research stations at Areka and Hawassa, which took us on a 600-km round tour, out of the capital Addis Ababa and into the Great Rift Valley beyond.

We set off early that cool morning, and as we headed into the countryside, I glimpsed many a local taking their first breath of morning air as they stepped outside from their decoratively-painted, round, thatched-roof homes, and shook the night’s sleep from their shoulders.

Traditional thatched living rooms

So their day began – already there was smoke coming from the chimneys, and I imagined the lady of the house beginning to prepare for the first coffee ceremony of the day. Coffee is often accompanied by a dish of boiled red beans. Or maybe she was warming the pan for the morning injera – a kind of ‘teff tortilla’: a sour-dough thin pancake made of the local cereal, teff. Injera is an iconic ubiquitous component of Ethiopian cuisine, with which diners take all manner of wat, or stew made from a rich variety of ingredients – from legumes to raw meat, carefully rolling the spongy crepe around the filling twice, making sure no food falls onto the fingers, for dining etiquette strictly dictates against the licking of fingers.

Ensete plantations

Living landscape

We pass score upon score of the gently-smoking thatched round huts – the traditional ‘living rooms’ in these parts; most dwellings are accompanied by modest smallholdings, with maybe a grazing goat or two, and many more with plantations of ensete – a banana-like plant, which, in spite of its inedible fruit, has long been a staple in Ethiopia. It is used for its root, which is mashed to make a tasty, stodgy, bread-like food called kocho, used to accompany meals, a denser cousin of the favourite injera. These smallholdings would also be the perfect size for cultivating beans, as they are not an acre-hungry crop, but grow happily on small plots of land, and in some areas are intercropped with ensete to maximise the space.

Dromedaries, drought and beans

Our common legume: the bean, Phaseolus vulgaris L

Into this landscape we pass the incongruous addition of a herd or two of camels with their owners…significantly peculiar as these aren’t desert lands, but the edge of the Ethiopian highlands, gradually and graciously giving way to the majestic Great Rift Valley below. I ask my guide about the addition of camel hands to this highland scenery: he explains their strange presence is due to a growing food shortage which has forced these nomadic peoples further afield to find their fare. The appearance of these dromedaries and their human partners brings harshly to mind Ethiopia’s most notorious claim to fame – especially for anyone who recalls the mid-1980s – for whom Ethiopia will always be indelibly synonymous with famine. It also throws the work of GCP, and specifically TLI, sharply into the spotlight, for the over-arching objective of this project is to improve legume productivity in environments considered marginal for agriculture, due to heat and other stresses. Somehow, it seems that more of the world’s environment is becoming ‘stressed’ by the day, though luckily the giant beanstalk of our story is a hardy crop which can be grown on the poor soils and fragmented plots of these challenged lands.

L–R: Asrat Asfaw Amele (SARI), Bodo Raatz (CIAT) and Daniel A Demissie (Areka Research Station) discuss the A–Z of beans at Areka Research Station.

So the legume of choice for this most uncommon road trip is the common bean, Phaseolus vulgaris L, and our Ethiopian bean breeding expert is Asrat Asfaw Amele of the Southern Agricultural Research Institute (SARI), who is the Lead Scientist of the TLI beans component in Ethiopia. Asrat is our friendly guide and fount of knowledge of all things Ethiopian throughout this impassioned passage into the ‘bean valley’, and we are accompanied by Bodo Raatz of the Centro Internacional de Agricultura Tropical (CIAT), recently appointed Principal Investigator of TLI’s bean research. At Areka research station we are joined on our journey by Daniel A Demissie, who, along the way, shares his many insights on beans, diseases such as bean stem maggot (BSM), and on drought . We are chaperoned throughout by our courageous driver, Mr Abebe, who at times resembles a pilot as we seem to fly over the bumpy terrain in the plucky pick-up that is our steed for the day.

Impact

Asrat Afaw Amele

Against the scenic backdrop of the Ethiopian landscape racing by, with background music courtesy of Teddy Afro (whose politically charged songs, sweet voice and infectious rhythm have made him nothing short of a legend in his homeland), I take advantage of this long and winding road trip to interview Asrat, where his answers echo the whirlwind tour rushing by outside – from a description of the landscape he knows so well, and toils in every day – to the impact that this project has had on national scientists, the impacts on farmers’ lives, as well as impacts that are likely to come in the not-too-distant future.

We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start to get wider adoption.” – Asrat Asfaw Amele (pictured).

The rich Ethiopian landscape

Revolution, alliances & partnerships

Ethiopia’s rich history, as varied as its topographical landscape, has known its fair share of extreme rulers. Now it seems the new ‘regime’ calling the shots is climate change, whose ravaging effects are seen worldwide, and no less in the bean fields of Ethiopia. Asrat even pinpoints climate change as the greatest challenge for the next generation of bean researchers, saying, “The farmers’ growing environment may be modified or a new environment may be created. That could also be a challenge – a new pest population or new disease may come; so the challenge in the future may be to breed or develop varieties which adapt to the changing environment.”

Beans line up at Awassa Research Station

The revolutionaries needed to overthrow this ‘tyrant’, it seems, are those of the ‘triple alliance’ partnership, comprising: Ethiopia’s national scientists, researchers from the international science community including CGIAR Centres, and farmers. Firstly, with this approach, the science sector can understand farmers’ needs, which also has a reciprocal effect, as Asrat explains, “We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start are widely adopted.” Secondly, national and international science systems come together to work for a common goal – in Asrat’s words: “Now we’ve got the knowledge and we can speak a common language with people from advanced laboratories. It’s also brought us closer to international institutes like CIAT and other CG Centres – we work together, so they understand our system better and we understand how they function.” He adds, “We are getting technical backstopping from CGIAR Centres, so as a national partner we are doing work, and they are supplying germplasm. That’s the partnership that will continue in the future.”

The weapon used by this ‘revolutionary army’ is GCP’s double-barrelled approach which combines both traditional and molecular breeding practices and is proving to be effective in developing new, more productive bean varieties to combat drought and disease. Specifically of the TLI project, Asrat says, “It lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.”

Daniel A Demissie contemplates looming rain clouds across the parched terrain

The ‘monster’, climate change, rears its ugly head only to be shot down expertly by Asrat and the mighty beans as he reveals, “A lot of farmers are growing our varieties, and, because of changing weather or instability, many people are starting to grow beans; beans are now becoming a major crop, especially in our mandate area.”

Capacity building …
At this stage, the major impact of the TLI beans component in Ethiopia has been on capacity building – both in terms of human resources and physical infrastructure, as Asrat illustrates, “In our breeding programme, capacity building has been an important aspect: scientists in our national system are being exposed to new technology, information, and training; we also have a full irrigation system in about 10 hectares of land, which will revolutionise our work.”

Magical bean diversity

… and on to farmers
By building on lessons learnt throughout this project, current impacts for the national science system will be translated into ‘real impacts’ in farmers’ fields in the near future. Indeed, Asrat hopes his future work will involve “getting the material into the hands of farmers, to see some impact or change, and to modernise and speed up breeding processes using markers developed by this project.”

Beanstalks: giant potential in Ethiopia

So the ‘magic beans’ of our story tell of a rich brew brimming with such potent ingredients as molecular breeding, capacity building, partnerships spanning continents and research systems, true teamwork with the farmers in the fields, and the drive to conquer the new challenge of a changing climate.

The impacts from the TLI project are the pot of gold at this rainbow’s end, showing that fairy tales do come true, where ‘magic beans’ put down roots and grow real shoots, and are not just ‘castles in the air’.
