Mission possible for ‘Generation Open’: open access and open attitudes for Open Access Week

Imagine the scene: it is the dead of night, and you are engaged on a dangerous mission. You are tense, alert for any noise. You must complete your task without being seen, or risk the shame and humiliation of failure… but it is not a pleasant undertaking!

Your mission? A critical matter of honour. To dispose of your family’s cassava peelings – not with the rest of your household waste, but smuggled into the murky depths of the pit latrine. Why?

“The stigma about cassava is mostly among the Kikuyu people of central Kenya,” explains Henry Ngugi, Kenyan scientist and former Maize Pathologist for Latin America at the International Maize and Wheat Improvement Center (CIMMYT). “Traditionally, the Kikuyu are very proud, and self-sufficiency in basic needs such as food is an important factor in this. That is, you cannot be proud if you cannot feed yourself and your family. Now, the other part of the equation regarding cassava is that, traditionally, cassava was eaten during seasons of severe food shortages. It is a hardy and drought-tolerant crop so it would be available when the ‘good food’ was not. This also meant that it was associated with hunger and poverty – inability to feed oneself.”

“Another factor that may have played a role in the way the Kikuyu view cassava is that some of the traditional cultivars produced high levels of cyanide and were toxic [if not properly cooked], so as a crop it was not very highly regarded to start with. Improved cultivars have been bred to remove this problem. But because of these issues, many people would not want their neighbours to know they were so hungry they had to rely on cassava, and would go to great lengths to conceal any evidence!”

The story is not the same everywhere: graceful and strong, this farmer tends her field of cassava, in the village of Tiniu, near Mwanza, northern Tanzania.

Opening up for Open Access Week

This year, 20–26 October is Open Access Week, a global event celebrating, promoting and sharing ideas on open access – that is, making research results, including both publications and data, freely and publicly available for anyone to read, use and build upon. Even more exciting for us, this year’s theme is ‘Generation Open’, reflecting the importance of students and researchers as advocates for open access – a call that falls on fertile ground at the Generation Challenge Programme (video below courtesy of UCMerced on YouTube).

We at GCP have been reflecting this week on different virtues of openness and transparency, and the perils of shame and secrecy. But before we go on, we’re sticking with cassava (carrying over from World Food Week!) but crossing the globe to China to celebrate the latest open-access publication to join the GCP parade. ‘Cassava genome from a wild ancestor to cultivated varieties’ by Wang et al is still practically a newborn, published on the 10th of October 2014.

The article presents draft genome sequences of a wild ancestor and a domesticated variety of cassava, with additional comparative analyses with other lines. It shows, for example, that genes involved in starch accumulation have been positively selected in cultivated cassava, and those involved in cyanogenic (ie, cyanide-producing) glucoside formation have been negatively selected. The authors hope that their results will contribute to better understanding of cassava biology, and provide a platform for marker-assisted breeding of better cassava varieties for farmers.

The research was carried out by a truly international team, led by scientists from the Chinese Academy of Tropical Agriculture Sciences (CATAS) and Chinese Academy of Sciences (CAS). Authors Wenquan Wang of CATAS and Bin Liu of CAS are delighted that their publication will be freely available, particularly in a journal with the prestige and high impact of the Nature family. As they observe, the open access to the paper will spread their experience and knowledge quickly to every corner of China and of the world where people have internet connections.

The work incorporated and partially built upon previous work mapping the cassava genome, which was funded by GCP in our project on Development of genomic resources for molecular breeding of drought tolerance in cassava (G3007.03), led by Pablo Rabinowicz, then with the University of Maryland, USA. This provides a perfect example of the kind of constructive collaboration and continuation that open access and sharing of research results can facilitate: by building on what has already been done, rather than re-inventing the wheel or working in isolation, we share, disseminate and amplify knowledge more rapidly and efficiently, with win–win outcomes for all involved.

One thing that makes the latest research even more special is that it was published in Nature Communications, which marked Open Access Week by going 100 percent open access from the 20th of October, making it an open-access flagship within the Nature Publishing Group – a clear indicator of the ever-increasing demand for and credibility of open-access publishing. We congratulate all of our open-access authors for making their work publicly available, and Nature Communications for its bold decision!

A matter of perspective: turning shame to pride and fears to opportunities

No shame here: a little girl clutches a cassava root in Kenya.

Of course, human beings worrying about their social status is old as humanity itself and nothing new. Food has never been an exception as an indicator. Back in mediaeval Europe, food was a hugely important status symbol: the poor ate barley, oats and rye, while only the rich enjoyed expensive and prestigious wheat. Although our ideas about what is luxurious have changed – for example, sugar was considered a spice thanks to its high cost – rare imported foods were something to boast about just as they might be today.

But why are we ashamed of eating the ‘wrong foods’ – like cassava – when we could take pride in successfully feeding our families? Many of the things we tend to try to hide are really nothing to be ashamed of, and a simple change in perspective can turn what at first seem like weaknesses into sources of pride (and there are two sides to the cassava saga, as we shall see later).

Throughout its existence, GCP has been characterised by its openness and transparency. We have worked hard to be honest about our mistakes as well as our successes, so that both we and others can learn from them. The rewards of this clear-eyed approach are clearly noted in our Final External Review: “GCP has taken an open and pro-active attitude towards external reviews – commissioning their own independent reviews (the case of the current one) as well as welcoming a number of donor reviews. There have been clear benefits, such as the major governance and research reforms that followed the EPMR [External Programme and Management Review] and EC [European Commission] Reviews of 2008. These changes sharply increased the efficiency of GCP in delivering benefits to the poor.”

Transparent decision-making processes for determining choices of methods have also improved the quality of our science, while open, mutually respectful relationships – including open data-sharing – have underpinned our rich network of partnerships.

One aspect of this open approach is, of course, our commitment to open access. All of our own publications are released under Creative Commons licences, and we encourage all GCP grant recipients to do the same, or to pursue other open-access options. When exploring our research publications you will note that many are directly available to download. Our website will act as an archive for the future, ensuring that GCP publications remain online in one place after GCP’s closure in December this year. See our Global Access Policy and our policy on data-sharing.

“Open access journals are just terrific,” says Jean-Marcel Ribault, Director of GCP. “It’s great to enable access to publications, and it’s important to promote sharing of data and open up analysis too. The next big challenge is data management, and assuring the quality of that data. At the end of the day, the quality of the information that we share with others is fundamental.”

That’s a challenge that many other organisations are also grappling with. Richard Fulss, Head of Knowledge Management at our host CIMMYT is currently working on standards and approaches for the quality and structure of data, with the aim of implementing open access to all data within five years, meeting guidelines being put in place across CGIAR. “The issues to resolve are threefold,” he explains. “You have a licence issue, a technology issue – including building the right platform – and a cultural issue, where you need to build a culture of knowledge sharing and make open access publishing the norm rather than the exception.”

Our partners at the International Center for Tropical Agriculture (CIAT) already have a strong open-access policy, and are debunking some cherished open-access myths.

It’s good to talk: saying no to secrecy

Back to cassava, and of course not everyone feels the same way about the same crop, as there are many sides to any story. In China, demand for cassava is soaring – for food, for animal feed and most of all as a raw material for starch and biofuel production – making breeding of resilient, productive cassava varieties even more important. Even within Kenya, there are those who are quicker to see the crop’s virtues. The Luhya people of western Kenya often mix cassava with finger millet or sorghum to make flour for ugali (a stiff porridge or dough eaten as a staple food in vast swathes of Eastern and Southern Africa). As Henry explains “one reason was that such ugali ‘stayed longer in the stomach’ in literal translation from local parlance meaning it kept you full for longer – which is scientifically sound because cassava has a crude starch that takes longer to digest, and lots of fibre!”

Meanwhile, watch the delightful Chiedozie Egesi, Nigerian plant breeder and molecular geneticist, in the video below to hear all about the high potential of cassava, both as a food in itself and as a raw material to make flour and other products – something some farmers have already spotted. “Cassava can really sustain a nation… we’ve seen that it can,” he says. “You have in Nigeria now some of the Zimbabwean farmers who left Zimbabwe, got to Nigeria, and they changed from corn [maize] to cassava, because they see the potential that it has.”

The power of openness is already showing itself in the case of cassava, as well as other root, tuber and banana crops. Check out RTBMaps, an online atlas developed by the CGIAR Research Program on Roots, Tubers and Bananas (RTB), using ‘scientific crowdsourcing’ to combine data on a wide range of variables, shared by many researchers, in a single map. Putting all that information together can help people make better decisions, for example on how to target breeding, or where disease threats are likely to be strongest. And for a sweet serving, here’s our humble contribution from Phase I to a world-favourite dessert!

We leave you with one final thought. It is not just cassava that is plagued with pride and prejudice; many foods attract high or low statuses in different regions – or even just variations of the same food. People in Asia and North America, for example, tend to prefer yellow maize, while Africans like their maize white. In fact, yellow maize still carries a powerful stigma in many parts of Africa, as this was the colour of the maize that arrived as external aid in periods of famine, oftentimes perceived in Africa as animal fodder and not human food in the countries it was sourced from. And thus yellow maize became synonymous with terrible times and the suffering and indignity of being unable to feed oneself and one’s family. Consequently, some of the famine-stricken families would only cook the yellow ‘animal-fodder’ maize in the dead of night, to avoid ‘detection’ and preserve family pride and honour.

This might at first blush appear to be a minor curiosity on colour and coloured thinking, were it not for the fact that when crops – such as sweet potato, cassava, or indeed maize – are bred to be rich in pro-vitamin A, and so provide plenty of the vitamin A that is particularly crucial for young children and pregnant women, they take on a golden yellow-orange hue. When promoting the virtues of this enriched maize in parts of Africa, it’s vital to know that as ‘yellow maize’ it would fall flat on its face, but as ‘orange maize’ or ‘golden maize’ it is a roaring success. A tiny difference in approach and label, perhaps, but one that is a quantum leap in nutritional improvement, and in ‘de-stigmatisation’ and accelerating adoption. Ample proof then that sharing details matters, and that it’s good to talk – even about the things we are a little ashamed of, thereby breathing substance into the spirit of the theme ‘Generation Open’.

Do have some of these uncomfortable but candid conversations this Open Access Week and live its spirit to the fullest every day after that! As for us here at GCP, we shall continue to sow and cultivate the seeds of Generation next for plant breeding into the future, through our Integrated Breeding Platform which will outlive GCP.

Poverty eradication through crop breeding for abundant harvests

Crop breeding, Drought, GCP, Poverty eradication No Responses »

Oct 152014

In recognition of the International Day for the Eradication of Poverty, October 17th, we are reflecting on what poverty means, how crop breeding helps eradicate poverty and transform lives, and how we have tried to maximise and measure those impacts.

In the early days of GCP, we were largely on uncharted seas and needed to chart a course to where our efforts would have the greatest impact, a process documented in our Pathways to impact brief No 1: Where in the world do we start? Instead of using a monetary definition of poverty, since this varies so widely between places and contexts, we took a different approach. As an indicator of true poverty, we used data on the number of stunted – ie, severely malnourished – children, overlaying this on maps showing where drought was most likely to occur. Our thinking was clear and simple: poverty + drought = where GCP needed to be.

Whatever else you may think they may lack, these children in Sibi village, Burkina Faso, definitely have verve, and look full of the energy they need to play!

A boy plays with an improvised hoop in Lukolela, Democratic Republic of Congo.

Drought routinely reduces harvests, and can be catastrophic. For example, nearly half (40 percent) of Africa’s maize-lands face occasional drought, reducing yields by between 10 and 25 percent, while a quarter suffers frequent drought, with overall losses of up to half the harvest – and total losses for some individual farmers. With climate change making droughts ever more common, drought was a natural priority for GCP from its inception.

Drought-tolerant crops are therefore the most important focus for the breeders of the GCP family, though not an exclusive one. Other key traits our breeders consider include resistance to pests and diseases and nutritional fortification, depending on the crop and location – and of course all varieties should yield well in good years too. Resilient improved varieties are particularly important for the poorest farmers, as they do not usually have access to measures such as irrigation or pesticides to combat environmental menaces. Typically, the poorest farmers also live in the most drought-prone drylands. Helping poor farmers to reap consistently abundant nutritious harvests means more food for their families and often a surplus to sell –reducing child malnourishment, and poverty in general.

Together we stand

The theme of the International Day for the Eradication of Poverty 2014 is Leave no one behind: think, decide and act together against extreme poverty, and it is one that echoes beautifully with the ethos of GCP. Collaboration and partnership have always been hallmarks of our approach, particularly in terms of empowering researchers in developing countries to implement – and lead – cutting-edge science. You can find a wealth of posts on our blog about our partnerships and the ‘GCP spirit’.

Collaboration is particularly important in crop breeding because one crop is often faced by all kinds of threats at once – a selection from the world’s least tasty smorgasbord of drought, heat, waterlogging pests, diseases, soil infertility, and much more. It is likely to be of no use breeding a super-crop that goes untouched by disease if it turns up its toes after a few dry days, or if no one likes the taste. That means researchers with different areas of expertise need to work together – and with farmers and extensionists too. Read the case for collective action in our Pathways to impact brief No 2: A call for collective action in agricultural research.

Impact by the numbers

GCP believes that using marker-assisted breeding (a range of efficient crop-breeding approaches that use genetic information to work out which plants have useful traits) to create improved varieties faster and more effectively is worth its extra cost, and has a real impact on farmers’ incomes. This cannot be taken for granted however, so get an introduction to the numerical approach in our Pathways to impact brief No 3: Molecular and conventional breeding through an economic lens. Our study found that women in Nigeria reported increased household incomes from growing improved cassava varieties, but also more time spent on cassava-related tasks – emphasising the need for researchers to be aware of the characteristics farmers – in this case predominantly women – value.

As we mark this year’s International Day for the Eradication of Poverty, we at GCP are proud to be contributing to the eradication of poverty by creating partnerships, expertise, and ultimately crop varieties that promise abundant harvests for the world’s poorest farmers and their families – helping their children grow up big, strong and free from poverty.

Things fall apart… and come together

By Eloise Phipps

Cassava – the tough, gutsy daughter of a poignant confluence of cultures, and the benevolent mother of millions when times get tough – is bursting onto the science scene after years of neglect. For October 15th, the International Day of Rural Women, we crown her the Queen of Crops. Read on to see why …

His mother and sisters worked hard enough, but they grew women’s crops, like coco-yams, beans and cassava. Yam, the king of crops, was a man’s crop.”

So wrote Chinua Achebe in his great novel, Things Fall Apart, set among the Igbo people in southeast Nigeria. His words are a reminder that men’s and women’s experiences, needs, activities and ambitions in the agricultural sphere can often be different – and that women’s contributions are all too often undervalued.

Cassava feeds more than half a billion people in the in the developing world. After rice and maize, it is the third-largest source of carbohydrates for people in the tropics, where it is grown across Africa, Asia and Latin America. Yet tough, unassuming cassava is a bit of an underdog – just like the women who grow it. We are celebrating the International Day of Rural Women by taking a special look at cassava, what it means for women, and the extraordinary things that can happen when Things Come Together!

A bright spot in a sea of green: a farmer in her field of cassava, in the village of Tiniu, near Mwanza, northern Tanzania.

It thrives on poor soils where other plants struggle, and it survives droughts that leave other crops biting the dust. For many rural mothers, cassava is the crop that keeps their families alive…”

“We must sing for you, great cassava…”

Hefty chunks of cassava – full of energy and nutrients – on sale in Kampala, Uganda.

Cassava’s story is one that is inextricably linked to centuries of pain and struggle. It was introduced to Africa in the 16^th century by Portuguese traders who brought it from Brazil – and took Africans back to Brazil as slaves.

Yam, native to Africa, was firmly established as the staple food of the Igbo people. Dominating their farming activities, it thus dominated the very routine of existence. So, control of yam affirmed men’s position at the top of the pinnacle. When cassava arrived, no one thought very much of it. For the Portuguese, it was a cheap source of carbohydrates. For the Igbo, it was a decidedly inferior crop to the long-beloved and much-revered yam.

Since the men were generally not much interested, Igbo women gradually adopted cassava as ‘their’ crop, a process that has been reinforced over the centuries. For example, Nigerian troop conscription during the First World War and the subsequent influenza pandemic caused a serious shortage of labour, particularly manpower. Women needed to grow more food, and cassava – more flexible and less labour-intensive than yam – was the natural choice, being also free from the cultural constraints that made yam the exclusive domain of men.

While no one would call cassava glamorous, plenty of women over the years have turned out to be quite happy that such a valuable crop ended up in their sphere of influence. While cassava is not often much of a cash crop in Africa, it is tough, resilient, and very useful for survival in difficult times. It thrives on poor soils where other plants struggle, and it survives droughts that leave other crops biting the dust. For many rural mothers, cassava is the crop that keeps their families alive.

What better words to sing cassava’s praises than those of Flora Nwapa, Nigeria’s first female novelist, in her Cassava Song? In ancient Igbo tradition, women sing their work, singing it into being and into completion, and her poem is a tribute to those work-songs.

And here, we have another Nigerian to join the chorus of praise – watch Emmanuel Okogbenin, molecular plant breeder, on the importance of cassava:

While our spotlight on Nigeria thus far has been purely coincidental, let’s also not forget that Nigeria is the global cassava giant, being far and away the world’s biggest producer and consumer of cassava. But do buckle up and let’s cross the great ocean, to another part of the planet, for an equally captivating cassava story…

… legend has it that the first cassava was birthed by a human woman…”

Crossing continents: A virgin-born, Amazonian Snow White planted in the earth

Of course, cassava is not exclusively a female province – it is grown by both women and men farmers around the world. But can you blame us for imparting it with a special feminine mystique, when legend has it that the first cassava was birthed by a human woman caught at the confluence of two cultures?

Many centuries before the Europeans arrived, cassava – often known in the New World as manioc – sustained peoples and cultures throughout the tropical lowlands of the Americas. The Tupí people of Brazil tell how, many years ago, the daughter of a chief became pregnant. Although she said that she had not been with a man, her father did not believe her, and threatened to kill her if she did not tell him the name of the child’s father. When he slept, however, he dreamt of a white-skinned warrior who told him that his daughter was telling the truth, and that one day, she would bear a great gift for all his tribe.

The chief’s daughter gave birth to a little girl, Maní, whose skin was as white as the moon and eyes were as dark as the night. She grew into a happy and beautiful baby, but died suddenly after her first birthday. Her mother watered the grave every day, as was the custom, and one day, a strange plant grew there that no one had ever seen before. Later, the earth cracked open, and the Tupí people saw a fruit that was as white as the dead child. They drew it from the ground, peeled and cooked it, and to their surprise found that it was delicious, and even renewed their strength. They called it mandioca or manioca, meaning ‘House of Maní’.

It is a haunting tale, rich with echoes of the cultural upheavals that followed the coming of the Europeans, ancient fears of female impurity, and the realities of infant mortality. But it leaves one thing in no doubt: poor little Maní’s legacy was a precious treasure, not just for the Tupí but for the world.

A busy Bea grows her way to cassava glory – with a little help from her friends

Female farmer reloaded: Being a rural woman farmer does not mean you have to have dirt under your fingernails all the time. Here’s Bea looking as elegant and regal as any queen.

Ghanaian cassava researcher Elizabeth Parkes is no puny pushover, but even so she met her match in gutsy and determined farmer Bea. Elizabeth laughs as she remembers how the story began: “She hadn’t planted cassava before in her life, but she wanted to go into cassava production. She came to me – she pestered me actually! I was tired of it, because she didn’t know anything and it was a time when I was finishing my PhD, and I thought no, this lady cannot take this precious time from me.”

When most people think of a farmer, they probably think of a man in a straw hat. But in defiance of this stereotype, women make up 43 percent of the agricultural labour force in developing countries, rising to at least 50 percent in sub-Saharan Africa and Eastern Asia. These millions of rural women have incredibly diverse lives, but a few things stay surprisingly constant. Female farmers tend to produce less than their male counterparts – not because they are worse at farming, but because they have less access to all kinds of resources and opportunities. These include anything from land itself to improved seed and new technologies, and from education and information to financial credit.

If this gap could be completely sealed, women could increase their harvests by 20 to 30 percent, translating to millions fewer hungry and malnourished people worldwide. Fortunately, with the right kind of support, female farmers can – and do – transform their lives in remarkable ways. Bea’s story came to just such a happy ending: with guidance from Elizabeth, her cassava-growing skills took off like a rocket, and she became so successful that she was recognised as the best farmer in her community. “These are things that make me glad… that at least I have impacted somebody who hadn’t planted cassava before, and it’s amazing,” says Elizabeth. “There are people out there who need us, and when we give them our best, they will give the world their best as well.”

Listen to Elizabeth in the podcast below, and you are bound to pick up her infectious enthusiasm!

When scientists like these come together, with a dash of the right support, marvellous things happen… cassava has been given a voice.”

Things Come Together

Elizabeth Parkes is a woman from Ghana, and Chiedozie Egesi is a man from Nigeria, himself of the Igbo people and a yam breeder in a past life. However, the two have a lot in common. They are dynamic African scientists with a passion for social justice, and for helping the poorest and most disadvantaged rural people through their work on cassava. When scientists like these come together, with a dash of the right support, marvellous things happen.

Read Elizabeth’s story here and more from her here, and catch up with Chiedozie here and here.

Cassava has traditionally been a forgotten ‘orphan’ in crop science research. Humble and unfashionable, it also has some special challenges for breeders, like its long growth cycle and complicated genetics, while its tough and uncomplaining nature meant that many people thought of it as an “anywhere, anyhow” crop – a very misleading myth, if ever there was one (with thanks to myth-buster Joseph Adjebeng, for that memorable cassava quote). Although the idea grew from a kernel of truth, cassava, like any other crop, needs a little love, and yields less when plagued by problems such as diseases or degraded and infertile soils. But, like Harry Potter, in recent years this orphan has come out from the cupboard under the stairs, and the magic has begun.

Wreathed in sunlight and smiles, a cassava farmer inspects her crop in Kratie, Cambodia.

Cassava’s no waif – luckily, as its tuberous roots are packed with staple carbohydrates. Here Ghanaian researcher, Elizabeth Parkes, shows off some huge and healthy cassava. These days Elizabeth is a pro when it comes to things crop-related, but it was not always so. “I remember we used to uproot volunteer cocoyam from a serious, busy lady farmer’s farm and we put it in our garden expecting to have a fast-growing plant overnight,” she admits. “The crops died and the busy woman farmer had to come and warn us never to step in her farm again. That was the first hard lesson learnt.” Elizabeth remains ready to learn, with a healthy respect for the knowledge and skills of the farmers she works with, an attitude she learned early on when she visited cocoa farms near her home town. “I loved the way farmers called colleagues by making unique sounds,” she says. “There are many paths to the farm but everyone knew the many routes to our many farms. This still amazes me.”

The plus side of cassava being neglected for so long is that it only needed a relatively small initial investment in local capacity-building and applying modern breeding methods to make a big impact, and set the ball rolling for serious cassava research. “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,” explains Chiedozie.

His team have released new cassava varieties that are resistant to diseases and rich in pro-vitamin A, providing the vitamin A that is particularly important for small children and childbearing women. He believes that these have the potential to transform the lives of the people – mainly rural women – who grow them. “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,” he says.

Elizabeth agrees that a new, “blessed and privileged era” has begun for cassava. “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.”

It seems that things have come together for cassava at last, and for Elizabeth, the personal rewards of being able to make real impacts are great. “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.”

After all, it seems that being a ‘woman’s crop’ might not be a put-down, but something to celebrate. Cassava has come a long way, from a pale princess lying under the earth, to a steadfast mother keeping the family going in the toughest of times, to a confident and majestic queen with a glorious reign ahead of her.

And so, for October 15th, in honour of the International Day of Rural Women, we crown her the Queen of Crops. Long live Queen Cassava!

Triumphs and tragedies, pitfalls and potential of the ‘camel crop’

We travel through space and time, with a pair of researchers who have a pronounced passion for a plant brought to Africa by seafaring Portuguese traders in the 16^th century. Fastforwarding to today, half a millennium later, the plant is widespread and deep inland, and is the staple food for Africa’s most populous nation – Nigeria.

Meet cassava, the survivor. After rice and maize, cassava is the third-largest source of carbohydrate in the tropics. Surviving, nay thriving, in poor soils and shaking off the vagaries of weather – including an exceptionally high threshold for drought – little wonder that cassava, the ‘camel’ of crops is naturally the main staple in Nigeria. And with that, it has propelled Nigeria to the very top of the cassava totem pole as the world’s leading cassava producer, and consumer: most Nigerians eat cassava in one form or another practically every day.

Great, huh? But there’s also a darker side to cassava, as we will soon find out from our two cassava experts. For starters, the undisputed global cassava giant, Nigeria, produces just enough to feed herself. Even if there were a surplus for the external demand, farming families, which make up 70 percent of the Nigerian population, have limited access to these lucrative external markets. Secondly, cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are deadly in Africa. Plus, cassava is a late bloomer (up to two years growth cycle, typically one year), so breeding and testing improved varieties takes time. Finally, cassava is most definitely not à la mode at all in modern crop breeding: the crop is an unfashionably late entrant into the world of molecular breeding, owing to its complex genetics which denied cassava the molecular tools that open the door to this glamour world of ‘crop supermodels’.

But all is not doom and gloom, which inexorably dissolve in the face of dogged determination. All the above notwithstanding, cassava’s green revolution seems to be decidedly on the way in Nigeria, ably led by born-and-bred sons of the soil: Chiedozie Egesi and Emmanuel Okogbenin (pictured right) are plant breeders and geneticists at the National Root Crops Research Institute (NRCRI). With 36 years’ collective cassava research experience between them, the two men are passionate about getting the best out of Nigeria’s main staple crop, and getting their hands into the sod while about it: “I’m a plant breeder,” says Chiedozie, with pride. “I don’t just work in a laboratory. I am also in the field to experience the realities.”

Hitting two birds with one stone…two stones are even better!
As Principal Investigators (PIs) leading three different projects in the GCP-funded Cassava Research Initiative, Chiedozie and Emmanuel, together with other colleagues from across Africa, form a formidable team. They also share a vision to enable farmers increase cassava production for cash, beyond subsistence. This means ensuring farmers have new varieties of cassava that guarantee high starch-rich yields in the face of evolving diseases and capricious weather.

Chiedozie is one of cassava’s biggest fans. His affection for, and connection to, cassava is almost personal and definitely paternal. He is determined to deploy the best plant-breeding techniques to not only enhance cassava’s commercial value, but to also protect the crop against future disease outbreaks, including ‘defensive‘ breading. But more on that later…

Emmanuel is equally committed to the cassava cause. As part of his brief, Emmanuel liaises with the Nigerian government, to develop for – and promote to – farmers high-starch cassava varieties. This ensures a carefully crafted multi-pronged strategy to revolutionise cassava: NRCRI develops and releases improved varieties, buttressed by financial incentives and marketing opportunities that encourage farmers to grow and sell more cassava, which spurs production, thereby simultaneously boosting food security while also improving livelihoods.

Standing tall. Disease resistance and high starch and yield aside, farmers also prefer an upright architecture, which not only significantly increases the number of plants per unit, but also favours intercropping, a perennial favourite for cassava farmers.

Cross-continental crosses and cousins, magic for making time, and clocking a first for cassava

No one has been able to manufacture time yet, so how can breeders get around cassava’s notoriously long breeding cycle? MAS (marker-assisted selection) is crop breeding’s magic key for making time. And just as humans can benefit from healthy donor organ replacement, so too does cassava, with cross-continental cousins donating genes to rescue the cousin in need. Latin American cassava is nutrient-rich, while African cassava is hardier, being more resilient to pests, disease and harsh environments.

Thanks to marker-assisted breeding, CMD resistance from African cassava can now be rapidly ‘injected’ much faster into Latin American cassava for release in Africa. Consequently, in just a three-year span (2010–2012), Chiedozie, Emmanuel, Martin Fregene of the Donald Danforth Plant Science Center (USA) and the NRCRI team, released two new cassava varieties from Latin American genetic backgrounds (CR41-10 and CR36-5). These varieties, developed with GCP funding, are the first molecular-bred cassava ever to be released, meaning they are a momentous milestone in cassava’s belated but steady march towards its own green revolution.

Marker-assisted selection is much cheaper, and more focused.”

On the cusp of a collaborative cassava revolution: on your marks…
With GCP funding, Chiedozie and Emmanuel have been able to use the latest molecular-breeding techniques to speed up CMD resistance. Using marker-assisted selection (MAS) which is much more efficient, the scientists identified plants combining CMD resistance with desirable genetic traits.

“MAS for CMD resistance from Latin American germplasm is much cheaper, and more focused,” explains Emmanuel. “There is no longer any need to ship in tonnes of plant material to Africa. We can narrow down our search at an early stage by selecting only material that displays markers for the genetic traits we’re looking for.” Using markers, combining traits (known as ‘gene pyramiding’) for CMD resistance is faster and more efficient, as it is difficult to distinguish phenotypes with multiple resistance in the field by just observing with the naked eye. This is what makes marker-assisted breeding so effective and desirable in Africa.

GCP’s mode of doing business coupled with its community spirit has spurred the NRCRI scientists to cast their eyes further out to the wider horizon beyond their own borders.

By collaborating with research centres in other parts of the world, Emmanuel and Chiedozie have made remarkable strides in cassava breeding. According to Emmanuel, “GCP helped us make links with advanced laboratories and service providers like LGC Genomics. The outsourcing of genotyping activities for molecular breeding initiatives is very significant, as it enables us to carry out analyses not otherwise possible.”

We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

‘Defensive’ breeding: partnerships to pre-empt catastrophe and combat disease
Closer home in Africa, as PI of the corollary African breeders community of practice (CoP) project, Emmanuel co-organises regular workshops with plant breeders from a dozen other countries (Côte d’Ivoire, DR Congo, Ethiopia, Ghana, Kenya, Liberia, Malawi, Mozambique, Sierra Leone, Tanzania, Uganda and South Sudan). These events are an opportunity to share knowledge on molecular breeding and compare notes.

Of the diseases that afflict cassava, CBSD is the most devastating. Mercifully, in Nigeria, the disease is non-existent, but Chiedozie is emphatic that this is by no means cause for complacency. “If CBSD gets to Nigeria, it would be a monumental catastrophe!” he cautions. “We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

Putting words to action, though this work on CBSD resistance is still in its early stages, more than 1,000 cassava genotypes (different genetic combinations) have already have been screened in the course of just one year. Chiedozie hopes that the team will be able to identify key genetic markers, and validate these in field trials in Tanzania, where CBSD is widespread. This East African stopover, Chiedozie emphasises, is a crucial checkpoint in the West African process. So the cassava CoP not only provides moral but also material support.

And Africa is not the limit. GCP-funded work on CMD resistance is more advanced than the CBSD work, though the real breakthrough in CMD only happened recently, on the international arena within which the African breeders now operate. According to Chiedozie, two entire decades of screening cassava genotypes from Latin America yielded no resistance to CMD. The reason for this is that although it is widespread in Africa, CMD is non-existent in Latin America.

Through international collaborative efforts, cassava scientists, led by Martin Fregene (now based in USA), screened plants from Nigeria and discovered markers for the CMD2 gene, indicating resistance to CMD. Once they had found these markers, the scientists were off and away! By taking the best of the Latin American material and crossing it with Nigerian genotypes that have CMD resistance, promising lines were developed from which the Nigerian team produced two new varieties. These varieties, CR41-10 and CR36-5, have already been released to farmers, and that is not all. More varieties bred using these two as parents are in the pipeline.

“GCP funding has given us the opportunity to show that a national organisation can do the job and deliver.”

Delivery attracts
The success of the CGP-funded cassava research in Nigeria lies in its in-country leadership. Chiedozie, Emmanuel and Martin are native Nigerian scientists and as such are – in many ways – best placed to drive a research collaboration to benefit the country’s farmers and boost food security. “GCP funding has given us the opportunity to show that a national organisation can do the job and deliver,” says Chiedozie.

This proven expertise has helped NRCRI forge other partnerships and attract more financial support, for example from the Bill & Melinda Gates Foundation for a project on genomic selection. GCP support has also bolstered communications with the Nigerian government, which has launched financial instruments, such as a wheat tariff,* to boost cassava production and use.

[Editors note: * wheat tariff: The Nigerian government is trying to reduce wheat import bills and also boost cassava commercialisation by promoting 20 percent wheat substitution in bread-making. Tariffs are being imposed on wheat to dissuade heavy imports and encourage utilisation of high-quality cassava flour for bread.]

“The government feels that to quickly change the fortunes of farmers, cassava is the way to go,” explains Emmanuel. He clarifies, “The tariff from wheat is expected to be ploughed back to support agricultural development – especially the cassava sector – as the government seeks to increase cassava production to support flour mills. Cassava offers a huge opportunity to transform the agricultural economy and stimulate rural development, including rapid creation of employment for youth.”

The Nigerian government is right in step aiding cassava’s march towards the crop’s own green revolution, as is evident in the the Minister of Agriculture’s tweet earlier this year, and in his video interview below. See also related media story, ‘Long wait for cassava bread’.

Clearly, the ‘camel’ crop – once considered an ‘orphan’ in research – has travelled as far in science as in geography, and it is a precious asset to deploy for food production in a climate-change-prone world. As Emmanuel observes, cassava’s future can only be brighter!

“Women can do advanced agricultural science, and do it well!” Elizabeth Parkes, cassava researcher, Ghana

Being a woman scientist in today’s world (or at any time in history!) is no mean feat, science traditionally having been the domain of men. We are therefore drawn to this sub-theme: Inspiring change, in addition to the global theme Equality for women is progress for all, To mark International Women’s Day tomorrow, UNESCO has developed an interactive tool which collates facts and figures from across the world on women in science. The cold scientific truth displayed in the attractive petri dish design shows that only 30 percent of researchers worldwide are women.

At GCP, we have been fortunate enough to have a cross-generational spectrum of, not only women scientists, but that even rarer species, women science leaders – who head a project or suite of projects and activities, and who actively nurture and mentor future science leaders – to ultimately contribute to the fulfilment of our mission: Using genetic diversity and advanced plant science to improve crops for greater food security in the developing world. The United Nations has designated 2014 as the Year of Family Farming. GCP’s women researchers have contributed to improving the lives of their farming counterparts the world over, especially in the developing world where on average, 43 percent of the agricultural labour force are women, rising to 60 percent and 70 percent in some regions. (FAO)

Please mind the gap…to leap to that all-important initiation into science

UNESCO’s Women in Science interactive tool

The UNESCO tool mentioned above and embedded to the left allows users to “explore and visualise gender gaps in the pipeline leading to a research career, from the decision to get a doctorate degree to the fields of science that women pursue and the sectors in which they work” with this affirmation: “Perhaps most importantly, the data tool shows just how important it is to encourage girls to pursue mathematics and science at a young age.”

In our International Women’s Day multimedia expo, we profile the life and work of a selection of our smart scientific sisters through words, pictures and sound, to explain just how they overcame obstacles, from taking that first hurdle to study science at an early age, to mobility up the research rungs to reach the very top of their game, all the while balancing work, life and family.

A blogpost fest to introduce our first special guests

Masdiar Bustamam

We begin our show with a blogpost fest, and first up is GCP’s original Mother Nature, renowned scientist and constant gardener of the molecular breeding plot, Masdiar Bustamam. After a virtual world-tour of research institutes early on in her career, Masdiar took the knowledge of molecular breeding back home, to the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD), where she personally took up the challenge to work with the fledgling world of biotechnology, set up a lab, and helped establish molecular breeding in her country. In an amazing 37-years-odd research career, Masdiar tended not only tender rice shoots, but also budding blossoms in the form of her many students, whom she nurtured and mentored throughout their studies, and who have now seamlessly inherited her mantle to carry on the mission with the same ever-bright spirit. More

Rebecca Nelson

We now skip continents and oceans to meet the feisty, continent- and crop-hopping scientist, Rebecca Nelson (Cornell University, USA). “I wanted to get out into the world and try and have a practical impact instead of doing research for the sake of research,” Rebecca says – and that she did, first leaving her native USA to work in the International Rice Research Institute (IRRI) in the Philippines. There she teamed up with friend and colleague, Masdiar Bustamam, to establish Masdiar’s laboratory at ICABIOGRAD, Indonesia. The American continent then called her back, where she moved countries and institutes, and switched from rice to maize research, marking the launch of her GCP experience – which simultaneously introduced her to her a whole new network of international crop researchers. This rich research tapestry was woven together by a poignant pain deep in her heart, as a mother herself, of “so many mothers not being able to feed their families.” Rebecca wanted to combat this problem, and crop science is her weapon. More

Zeba Seraj

Next, we meet another true mother of molecular plant breeding, Zeba Seraj (University of Dhaka, Bangladesh). Zeba, whose mind is perpetually on call in the pursuit of science, has been around the world, and from plants to animals and back again in the course of her multifaceted science career. During her PhD and postdoc experience in the UK, still with fauna, she cultivated her expertise in molecular biology and recombinant DNA technology, but a lack of opportunities in that field back in Bangladesh saw her enter the world of crop science, where she has remained ever since. Back at her alma mater, the University of Dhaka, she founded a molecular biology lab, and has nurtured and inspired generations of young biochemists. Her GCP project, using molecular markers to develop salt-tolerant rice, was a real eye-opener for her, and allowed her to truly ‘see’ how applied science and such a practical project would have a direct impact on her country’s food security, now and in the future. More

Sigrid Heuer

Our next scientist is also truly motivated by putting theory into practice through the application of upstream research all the way down the river, and directly into farmers’ fields. Sigrid Heuer (now with the Australian Centre for Plant Functional Genomics), a German national, has pursued her scientific ventures in Europe, Africa, Asia, and now Oceania, with many challenges along the way. Enter the Generation Challenge Programme, and the chance for Sigrid (then at IRRI) to lead a major project, the Pup1 rice phosphorus uptake project, which taught Sigrid the A–Z of project management, and gave her ample scope for professional growth. Her team made a major scientific breakthrough, which was not only documented in international journals, but was also widely covered by global media. From this pinnacle, Sigrid passed on the baton to other scientists and moved on to new conquests. More

Arllet Portugal

Now, all this research we’ve been celebrating generates a massive amount of data, as you can well imagine. What exactly can our scientists do with all that data, and how can they organise them? GCP’s Arllet Portugal, hailing from The Philippines, gives us the lowdown on smart and SHARP data management whilst also giving us some insights into how she started out on the long and winding road to leading data management for GCP’s Integrated Breeding Platform. In particular, Arllet describes the considerable challenge of changing researchers’ mindsets regarding the importance of effective data management in the context of their research, and enthuses over the excitement with which developing-country researchers welcome the GCP-funded electronic tablets they now use to collect and record data directly in the field. More

Armin Bhuiya

If there were a muse for young women scientists, it might very well be the subject of our next blogpost profile, Armin Bhuiya (Bangladesh Rice Research Institute). After completing her master’s degree on hybrid rice in her native Bangladesh, Armin was already thinking like a true change-catalyst scientist, trying to discover what line of research would be the most useful for her country and the world. After much deliberation, she embarked on a PhD focusing on developing salt- and submergence-tolerant rice. This wise choice would take her to study under the expert eye of Abdelbagi Ismail at IRRI, in The Philippines, with the helping hand of a GCP–DuPont postgraduate fellowship. There, she learnt much in the way of precise and meticulous research, while also taking advantage to self-train in modern molecular plant breeding methods. Our bright resourceful student has now advanced to the patient erudite teacher – as she takes home her knowledge of high-tech research methods to share with her colleagues and students in Bangladesh. More

Elizabeth Parkes

Hello Africa! Switching continents and media, we now we move from the written medium to tune in to the melodic tones of Elizabeth Parkes (Crops Research Institute [CRI] of Ghana’s Council for Scientific and Industrial Research [CSIR], currently on leave of absence at the International Institute of Tropical Agriculture [ IITA]). We’re now at profile number seven in GCP’s gallery of women in science. Elizabeth, who is GCP’s Lead Cassava Researcher in Ghana, narrates an all-inclusive engaging story on the importance to agriculture of women scientists, women farmers, and cassava the wonder crop – all captured on memorable sound waves in this podcast.

If the gravity of words inscribed holds more weight, you can also read in depth about Elizabeth in a blogpost on this outstanding sister of science. Witness the full radiance of Elizabeth’s work in the life-changing world in which she operates; as she characteristically says, “I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well.” And she is no exception to her own rule, as she grew professionally, apparently keeping pace with some of the giant cassava she has helped to develop through the years. But it is her role as nurturer, mentor and teacher that really raises her head-and-shoulders above the rest, from setting up a pioneering biotech lab at CRI–CSIR to conscientiously mentoring her many students and charges in work as in life, because, for Elizabeth, capacity building and cassava are inextricably coupled! More

Marie-Noëlle Ndjiondjop

In the wake of some recent high-profile screen awards, we close our multimedia expo with impressions of our science sisterhood through the medium of the seventh art: the magic visual world of the movies! A good fit for a Friday!

The following tasteful and tasty (you’ll see why!) blogpost takes our film fans right onto the red carpet to rub shoulders with our scientific screen stars!

The first screen star you’ll meet is Marie-Noëlle Ndjiondjop (Africa Rice Center), Principal Investigator (PI) of GCP’s Rice Research Initiative, who opens the video-viewing session with seven succulent slices of rice research delight. Her movies are set in the rice-growing lands of Africa, where this savoury cereal is fast becoming a staple, and tackles the tricky topics of rice-growing constraints, capacity building, molecular breeding methods, and the colossal capacity of community in collaborative research projects.

Jonaliza Lanceras-Siangliw

The following feature introduces the talented GCP PI Jonaliza Lanceras-Siangliw (BIOTEC, Thailand), whose community-minded project, set in the Mekong region, focused on strengthening rice breeding programmes by using a genotyping building strategy and improving phenotyping capacity for biotic and abiotic stresses. Though this title is something of a spoiler alert, we hope you tune in to this comprehensive reel to see the reality of molecular rice breeding in the Mekong. More

Soraya Leal-Bertioli

Last, and by no means least, is a captivating collage of clips featuring GCP researcher, Soraya Leal-Bertioli (EMBRAPA, Brazil) waxing lyrical about that hard genetic nut to crack: the groundnut, and how GCP’s Tropical Legumes I (TLI) project was crucial in getting the crop breeding community to share genetic resources, molecular markers, knowledge, and tools on a cross-continental initiative breaking boundaries in multiple ways.

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!

The Integrated Breeding FieldBook – An African agronomist’s perspective

Africa, Capacity building, Cassava, Crop information and data management, Integrated Breeding Platform No Responses »

Feb 242014

For this ‘IBP story-telling season’, our next stop is very fittingly Africa, and her most populous nation, Nigeria. Travel with us!

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.”

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.”

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

Africa, Capacity building, Cassava, Crop breeding, Researchers No Responses »

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.”

Visitors with working clothes on: NaCRRI Uganda’s Anthony Pariyo (left) and Williams Esuma (right) visiting NRCRI Umudike on a breeder-to-breeder visit in July 2012. Williams’ postgraduate studies were funded by GCP through the cassava CoP.

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 grand gathering: General Research Meeting (GRM) 2013

Closing GCP, Crop breeding, Events No Responses »

Participants at the 2013 GRM. High-resolution version on our Flickr account.

The General Research Meeting (GRM) is by far the largest and most important event on our calendar. This year’s GRM was held on September 27‒30 2013, with 135 people from 35 countries attending (see list).

Various presentations were made on progress and next steps on research in GCP projects, including for GCP’s Integrated Breeding Platform (IBP). Focus was on GCP’s nine focus crops in Phase II – beans, cassava, chickpeas, cowpeas, groundnuts, maize, rice, sorghum and wheat, with the poster sessions adding a couple more (see ‘sixty posters’ below). You can view the presentations made on our website (to see them in the context of the overall agenda), or on SlideShare (all gathered in one place). We have uploaded all but one presentation, where we’re still waiting for the presenter’s permission to publish. A comprehensive update on all GCP projects is here (PDF). The meeting was a blend of plenary sessions on core topics and research updates, and ‘drill-down’ breakouts on crops, data management and capacity building (the last two, in the context of IBP’s proposed Phase II, which had its own dedicated one-day stakeholder meeting after GRM, on 1st October).

Social were we…but we also did some heavy lifting
We didn’t just talk to ourselves: we made a bit of noise on social media to also bring in other voices into the GRM discourse and chit-chat, using the hashtag #GRM13, creating a good buzz of conversations. Also linking in to GRM were our LinkedIn followers. And neither was it all business, science and rigid structure: there was free-flow too, with an open afternoon where participants could take a relaxing break, organise their own meetings, or take a tour to Lisbon. Some of the scenes from the tour are posted on Flickr, as are other snapshots from the meeting. We’ve since gathered up some of the social media posts on Storify.

GRM was far from its grim-sounding abbreviation and hashtag on social media: exemplifying the best of the ‘GCP spirit’, the sessions were engaging, relaxed, conversational and spiced with humour and a light touch, despite the ‘heavy’ topics under discussion (see agenda). But the topic at hand was grim, since the situation is dire – drought affects almost all crops and all regions worldwide. As drought tolerance is our key focus since inception, most of the discussions naturally centred on this topic. Equally important is the scourge wrought by pests and disease, which afflict some crops more than others. For example, under most circumstance, cassava is naturally very drought-tolerant, but what good will this do if cassava survives drought only to succumb to the deadly pests and diseases that stalk this drought champion?

Sunset and ‘moon-rise’
GRM was also a time for both stocktaking and mapping the future given GCP’s sunset in 2014. A central and recurring theme was GCP’s transition strategy, and how – and where – to embed GCP-initiated projects that will extend beyond the Programme’s lifetime. For this, the CGIAR Research Programs (CRPs) are a natural first choice. GRM enjoyed a very good representation of the CRPs, with all six crop CRPs represented, some at the highest level.

A few members of our Executive Board also attended. Board Chair, Andrew Bennett, set the right tone for the meeting. In his remarks at the opening session, he emphasised that this was not a time for sadness, swan songs and moping as GCP approaches sunset. Rather, it was a time to appreciate the beauty of sunsets, in the sure knowledge that sunsets give rise to moon-rise!

“Say it succinctly in sixty seconds!”
The poster session was as lively as always, with a record of… (hold your breath!) 60 posters presented, surpassing the previous GRM in 2011 which attracted 53 posters.

Perfection! Sixty posters for sixty seconds
Sixty was a PERFECT number for the 60-second sizzle, where each poster presenter had a maximum of 60 seconds (and not a second more!) to present at plenary, devising whichever means necessary to attract the audience to their poster. It was easy to discern the brash ‘old hands’ who had perfected their art after several GRMs; the tricksters and various reincarnations of The Artful Dodger amongst them, trying to beat the clock; new and slightly jittery presenters who were more than just a little bewildered but still proved their mettle; and the new, sassy and confident. This beautiful blend apart, the poster session brought in not only new faces to add to the familiar ones, but also refreshing new tastes to diversify and sweeten our Staple of Nine crops. To our diet of cereals, legumes and tubers, poster presenters from The Philippines added eggplants, rounded off with bananas for dessert.

“Definitely time for dessert, and do not disturb!” they seem to be saying. Jean-Christophe Glaszmann (left) and Hei Leung (right), who played ace roles on a multi-partner GCP project on bananas.

♫ Welcome to the Hotel California! ♫…
As always, GRM was a mingling of old and new friends, a time for some paths to meet and for new forks to branch out, a season to reflectively look back and progressively face forwards. In keeping with Andrew’s continuity of sunsets giving way to moonrise, we said a group goodbye to Rajeev Varshney, former Genomics Theme Leader, who left the GCP Management Team in August. And we were happy to once again welcome, embrace and recognise two old friends – Jean Christophe Glaszmann (CIRAD) and Hei Leung (IRRI), who were, respectively ex-Subprogramme Leaders for genetic diversity and genomics in GCP Phase I, and continue to be involved with GCP as researchers, as will Rajeev.

In this picture, we caught up with them at a very appropriate moment: dessert during the Gala Dinner. Take it from us, these two guys are well versed in matters dessert, with a dash of science, as this blast from the past on bananas attests, also summarised in a Facebook photo-story here.

We are indeed a Hotel California of sorts – always open for check-in and checkout. As for leaving…we’re still working on the modalities of that!

And despite the fond farewell, truth is Rajeev is not going anywhere either, as far as GCP is concerned. You only needed to have been at GRM or following the conversations on Facebook and Twitter, especially the photos, to witness this. He was (delightfully!) all over the place, passing on his ‘positive epidemic’ of highly infectious enthusiasm and incredible energy. Here he is in action at the Gala Dinner in the photos below, which really need no caption. We’re sure you’ll be able to easily spot Rajeev, ‘high-fivin’ and ‘rapping’, eclipsing the GCP Director, who however appears quite pleased in his lower perch with Rajeev on the platform. But if you’re truly lost and can’t spot the super-charged high-energy guy in the photos, no worries! Here are some handy clues.

In distinguished company
Rajeev’s energy goes beyond GRM and GCP; this year as in previous ones, he received several awards, among them, the Young Crop Scientist Award by Crop Science Society of America, and the Illumina Agriculture Greater Good Initiative Award.

Hari Upadhyaya

Prior to these recognitions during the Gala Dinner, Jean-Marcel formally honoured ICRISAT’s Hari Upadhyaya (pictured) during plenary for two awards Hari had received in the course of the year, also from the Crop Science Society of America. These awards were for Hari’s notable contributions – at international level – to crop science, and to plant genetic resources.

Hari is a long-term GCP Principal Investigator, working primarily on sorghum. But that is not the only crop he works on. Hari was the lead author of the joint chickpea and pigeonpea chapter in our book on drought phenotyping.

Evaluation
Unlike other GRMs where we’ve requested participants to evaluate the meeting, we did not do so this year, since this is very likely the last meeting of its kind, and the goal of the evaluation is to use participant feedback to improve future meetings. With the help of our participants, we’ve applied the lessons we’ve learnt from them through the years to arrive at what we believe to be a winning combination, balancing the diverse interests of our participants for overall improvement of their GRM experience.
