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!

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…”

Cassava’s story is one that is inextricably linked to centuries of pain and struggle. It was introduced to Africa in the 16th 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.

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.

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’Cassava leaf. Photo: N Palmer/CIAT

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 16th 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 in science

“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)

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

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.

Rebecca Nelson

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.

Zeba Seraj

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.

Sigrid Heuer

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.

Arllet Portugal

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.

Armin Bhuiya

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.

Elizabeth Parkes

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!

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.

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 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 masters 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.”

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!

‘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!

Breathing life into support services

By addressing the needs at the heart of quality agricultural research, right there on the station, GCP was the first to cotton on to a crucial missing link between researcher, research station, and support services.” – Hannibal Muhtar

Want to cut to the chase and only need the bare bones of this story? Skip over to the short version

“One thing that really energises me,” enthuses GCP Consultant Hannibal Muhtar, “is seeing people understand why they need to do the work, and being given the chance to do the how.” And so was born another wonderfully fruitful GCP collaboration. Hannibal, who describes the assignment as “a breath of fresh air,” was asked to identify, together with GCP project Principal Investigators, African research sites of ongoing or potential GCP Research Initiative projects where effective scientific research might be hampered by significant gaps in one fundamental area: infrastructure, equipment and support services.

Meet Hannibal Muhtar (Audio clip)

As at June 2012, the 19 sites selected were:

Embarking on the voyage to change, storms ‘n’ all
Hannibal, armed with years of practical experience in the application of engineering sciences in agriculture and developing countries, as well as an attentive ear to the real needs of researchers, embarked on a series of visits to these research stations in 2010 and 2011, meeting with staff of all levels, departments and functions, carrying out in-depth analyses and draw up concrete recommendations for infrastructure and support service investments for each of the sites so that good-quality field evaluations (‘phenotyping’ in ‘breeder-speak) of GCP-funded projects could be conducted. Thanks to funding from GCP’s Integrated Breeding Platform (IBP), and to the openness, commitment and energy of research staff on the ground to implement these recommendations, the efforts of multiple cross-cutting partnerships across Sub-Saharan Africa are, in 2012, starting to bear fruit. But it has not all been smooth sailing, and the storms encountered along the way to reach this end goal should not be underestimated.

Weeds, wear and tear, and a walk on the wild side
The obstacles, says GCP’s Director of Research, Xavier Delannay (pictured, can often be mundane in nature – a  lack of or faulty weather stations or irrigation systems, or fields ravaged by weeds or drainage problems and in dire need of rehabilitation, for example. Yet such factors compromise brilliant research. A simple lack of fencing, Xavier and Hannibal expound, commonly results not only in equipment being stolen, but also in roaming cattle and wild animals – boars, monkeys, hippopotamus and hyena, to name but a few – stomping over precious experiment sites and posing serious threats to field staff safety. “The real challenge lies not in the science, but rather in the real nuts-and-bolts of getting the work done in local field conditions,” he explains.’’

Hannibal concurs: “If GCP had not invested in these research support infrastructure and services, then their investment in research would have been in vain. Tools and services must be in place as and when needed, and in good working order. Tractors must be able to plough when they should plough.’’

But a critical change is also needed in mindset and budgeting. ‘’The word ‘maintenance,’’’ a Senegalese partner commented to Hannibal, describing his institute, “does not exist in our vocabulary and is not a line-item on our budget.”

The problem then is not always about limited funds but rather much more on how the funds available are budgeted, excluding the all-essential support services.

Getting down to the brass tacks of local empowerment, and aiming higher
Multi-lingual and fluent in English, Arabic and French, Hannibal employed a multi-faceted customised approach, based on the needs of each site, be it sharing his tricks-of-the-trade and improvising local solutions, or guiding researchers in identifying their specific needs, as well as on where and how to request equipment, just to mention a few examples. In other cases he would teach local station managers to build and apply simple yet revolutionary tools such as land-levellers (referred to as ‘floats’ in industrial-speak), as well as row-markers for more uniform spacing between rows and plants in the field.

In addition, he would organise a training workshops in either English or French, with different content for technicians, machine operators and station managers. The dedication demonstrated by this latter group to both learn and continue these efforts after the training was particularly pertinent for ensuring the long-term sustainability of the investments.

A colourful menu of options, then, for achieving one common overarching objective, which, as summarised neatly by Xavier, is: “The effective running of local experiment stations, for facilitating local research, improving local crops, and ultimately leading to empowerment and self-reliance of local farming communities.”

“At the end of the day, it’s about achieving food security and improving livelihoods,” Hannibal emphasises. Looking back at some of the research stations that are now well-equipped and are being managed well, and the improved crop varieties being produced and projected, Hannibal highlights the “harmonious chain” triggered as a result: “Food security and better livelihoods pave way for healthy, well-fed families, and agriculture growing beyond subsistence into an economic activity,” Hannibal concludes.

Lights, curtain… ACTION!
Much like in theatre, with all the ‘props’ in place, Hannibal reports that field trials are now performing well, thanks to the all-important ‘backstage’ support service elements being in good shape. Hannibal likens the positive feedback from the partners he has worked with to “A glass of cold water, after a long day in the sun!”

And there’s a beautiful simplicity to the impacts described: “With proper infrastructure in place, and with research station staff duly equipped with the hands-on expertise and practical know-how to utilise and apply this infrastructure and training, we’re now seeing field experiments being conducted as they should be, and getting good-quality phenotyping data as a result,” says Xavier. “Moreover,” he continues, “by providing glass-houses or the capacity to irrigate in the dry season, we are enabling breeders to accelerate their breeding cycles, so that they can work all year round, rather than having to wait until the rain comes.” Sites hosting GCP projects on rice in Nigeria, as well as on sorghum and rice in Mali, are just a few examples of those enjoying off-season work thanks to new irrigation systems.

Similar good news is expected soon for cassava in Ghana and in northern Nigeria. And yet more good news: in some cases, the impacts have not been limited to the trials, or even to the research trials and stations alone, as Xavier highlights with an example from Kenya: “The establishment of an irrigation system on a plot at Koibatek Farmer Training Centre – a partner of Egerton University – yielded excellent results for chickpea experiments. We emphasised that we did not want the equipment to be ‘bracketed’ exclusively for science and experiments. So, it was also used to train staff and farmers from the local community as well. This was greatly appreciated.”

Seeing the nuts-and-bolts now firmly in place for the majority of the sites visited, Hannibal believes GCP has facilitated a pioneering approach to local capacity building: “By addressing the needs at the heart of quality agricultural research, right there on the station, GCP was the first to cotton on to a crucial missing link between researcher, research station, and support services,” he reveals.

…Another missing link…
But the job is not quite done. One crucial gap is the sensitisation of upper management – those at the helm of national research institutes and research station Directors – to support and sustain infrastructure, training and related services. In some cases, costs could be easily met by utilising a priceless asset that most institutes already have, and which they could put to greater us – land and a controlled environment.

Upper management needs to be actively on board. “A research institute should work like a good sewing machine,” says Hannibal. “All well-oiled, all parts working well, and everybody knowing what they need to do.”

In the meantime, however, results from the field suggest that researchers in GCP projects are already reaping the benefits from improved infrastructure and support services, and are already off to a good start.

The stage is therefore set: backstage and props are well primed, performance trials are acting like they should, and the ‘theatre directors’ have an eye on sustainability after GCP’s final curtain call in 2014.

So, long may the show go on, with a cautionary word, however, to continually seek ways to not only maintain but also enhance performance!
