CIMMYT’s work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.
Honoring the life and legacy of Fred Palmer

With sorrow we report the passing on June 14 of Anthony F. E. (Fred) Palmer, former maize agronomist and physiologist who contributed notably to the International Maize and Wheat Improvement Center (CIMMYT) networking and capacity building during crucial periods.
A British national, Palmer joined CIMMYT as a post-doctoral fellow in 1968 and retired from the center in 1996. With undergraduate studies in Agronomy at the University of Reading, Palmer completed masters and doctoral degrees in Crop Physiology at Cornell University. His early years at CIMMYT headquarters included work in maize physiology, agronomy and training.
In 1972 Palmer moved to Pakistan, serving as a production agronomist in that key Green Revolution setting until 1978, when he returned to Mexico as a training officer. “Fred was a true gentleman as a researcher and trainer,” said Stephen Waddington, retired CIMMYT maize agronomist who worked with Fred in Africa. “He was a mentor and friend to many junior CIMMYT staff, including myself, and countless trainees and visiting scientists from partner countries.”
Capitalizing on his experience and accomplishments, in 1985 CIMMYT posted Palmer to Nairobi, Kenya, as the team leader of the East African Cereal Project, funded by the Canadian International Development Agency (CIDA). During the project’s third phase, Palmer helped to establish and guide an entry-level crop management training program, in conjunction with the Kenya Agricultural Research Institute (KARI) and Egerton University, targeting maize researchers from eastern and southern Africa. Based at the university’s Njoro campus, the effort included construction of training facilities and guest rooms and Palmer successfully prepared Egerton administrators and faculty to take over the program, according to Joel Ransom, a North Dakota State University professor who served as a CIMMYT maize agronomist in Asia and sub-Saharan Africa.
“Scores of young agronomists mastered the fundamentals of on-farm research through that program,” Ransom said. “Palmer’s mentoring, training, and leadership greatly advanced the professional development of African maize and wheat scientists.”
Matthew Reynolds, CIMMYT distinguished scientist and wheat physiologist, recalls talking to Palmer about the latter’s efforts to apply fledgling tools for measuring photosynthesis in the field, a topic in which he had specialized at Cornell. “Fred was a very kind and unassuming man who treated everyone with respect, qualities that made him a great training officer and a well-regarded colleague,” said Reynolds.
Palmer firmly believed that national partners needed the capacity to train staff, particularly those fresh out of university studies, strengthening both their knowledge and professional linkages.
“By bringing young scientists together and working with them as a multidisciplinary research team,” Palmer wrote in a report on CIMMYT training in eastern and southern Africa, “it is anticipated that these scientists will learn to value each other’s work as essential to successful research.”
The CIMMYT community sends its warmest condolences to the Palmer family.

In 2018, CIMMYT continued to innovate and forge strategic alliances to combat malnutrition, tackle the effects of climate change and respond to emerging threats.
Building on the release of a new wheat genome reference map, our researchers more precisely tagged genes for valuable traits, including disease resistance, heat tolerance, and grain quality, in more than 40,000 CIMMYT wheat lines.
In collaboration with our partners, CIMMYT released 81 maize and 48 wheat varieties. More than 40,000 farmers, scientists and technical workers across the world took part in over 1,500 training and capacity development activities. CIMMYT researchers published 338 journal articles.
As the maize-hungry fall armyworm spreads from Africa to Southeast Asia, CIMMYT joined with more than 40 partners in an international consortium to advance research against the devastating insect pest.
CIMMYT used a scaling approach to extend the benefits of crop research to more farmers and consumers in developing countries in transformative and lasting ways. Smallholder farmers in Mexico, Pakistan and Zimbabwe are benefitting from the use of appropriate machinery and implements for efficient and climate-smart agriculture. A manual developed with the Food and Agriculture Organization (FAO) of the United Nations offers technical and business advice for local entrepreneurs offering mechanized services, such as sowing or threshing, to smallholder farmers.
As part of taste tests in Ethiopia, Kenya, and Tanzania, consumers indicated their willingness to pay a premium for quality protein maize (QPM), which contains enhanced levels of the amino acids needed to synthesize protein.
A CIMMYT-led study on gender has explored the lives and viewpoints of 7,500 men and women from farming communities in 26 countries, providing invaluable information that will lead to better productivity and food security.
2018 showed us that the passion and values of staff and partners help CIMMYT to have major impact on the livelihoods of smallholders and the poor. This Annual Report pays tribute to them.

Are high land rental costs pricing African youth out of agriculture?

A new study shows that youth can face higher land rental prices than older farmers in Tanzania and other parts of sub-Saharan Africa.
“The rising importance of land rental markets reflects increasing rural population densities in many parts of the continent,” said Jordan Chamberlin, an agricultural economist with the International Maize and Wheat Improvement Center (CIMMYT) and study co-author.
“Evidence that the effective costs of rental market participation are relatively higher for younger farmers suggests that the markets are not yet mature,” Chamberlin explained. “This appears to stem partly from weak contract enforcement norms that make land rental arrangements more sensitive to trust and reputation. That puts younger farmers, who have not yet built up such social capital stocks, at a disadvantage.”
As many as three-quarters of Tanzanian youth are employed in agriculture, and with rural populations in Africa expected to rise over the next several decades, the region will experience an increasing scarcity of land relative to labor.
Young people today are already inheriting less land than previous generations and waiting longer to obtain the land they do inherit, according to the authors, who observe as one result a rising dependence on labor markets.
“Wage income’s importance will continue to rise in rural areas of sub-Saharan Africa, but policymakers should also foster equitable access to land for young agricultural entrepreneurs,” said Chamberlin.
The authors recommend measures such as tenant-landlord “matchmaking” programs, arrangements that encourage land sales by older farmers to younger farmers, and clarifying and simplifying regulations and procedures for title conversions and land purchases.
“Local governments may also share information about land rental rates for different areas, to provide a reference for rental negotiations,” added Chamberlain.

Seeds of progress
The maize seed sector in east and southern Africa is male-dominated. However, there are women working in this sector who are breaking social barriers and helping to improve household food security, nutrition and livelihoods by providing jobs and improved seed varieties to farmers.
Researchers from the International Maize and Wheat Improvement Center (CIMMYT) conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies.
Millions at lower risk of vitamin A deficiency after six-year campaign to promote orange-fleshed sweet potato

STOCKHOLM, Sweden — Millions of families in Africa and South Asia have improved their diet with a special variety of sweet potato designed to tackle vitamin A deficiency, according to a report published today.
A six-year project, launched in 2013, used a double-edged approach of providing farming families with sweet potato cuttings as well as nutritional education on the benefits of orange-fleshed sweet potato.
The Scaling Up Sweetpotato through Agriculture and Nutrition (SUSTAIN) project, led by the International Potato Center (CIP) and more than 20 partners, reached more than 2.3 million households with children under five with planting material.
The project, which was rolled out in Kenya, Malawi, Mozambique and Rwanda as well as Bangladesh and Tanzania, resulted in 1.3 million women and children regularly eating orange-fleshed sweet potato when available.
“Vitamin A deficiency (VAD) is one of the most pernicious forms of undernourishment and can limit growth, weaken immunity, lead to blindness, and increase mortality in children,” said Barbara Wells, director general of CIP. “Globally, 165 million children under five suffer from VAD, mostly in Africa and Asia.”
“The results of the SUSTAIN project show that agriculture and nutrition interventions can reinforce each other to inspire behavior change towards healthier diets in smallholder households.”
Over the past decade, CIP and partners have developed dozens of biofortified varieties of orange-fleshed sweet potato in Africa and Asia. These varieties contain high levels of beta-carotene, which the body converts into vitamin A.
Just 125g of fresh orange-fleshed sweet potato provides the daily vitamin A needs of a pre-school child, as well as providing high levels of vitamins B6 and C, manganese and potassium.
Under the SUSTAIN project, families in target communities received nutritional education at rural health centers as well as cuttings that they could then plant and grow.
For every household directly reached with planting material, an additional 4.2 households were reached on average through farmer-to-farmer interactions or partner activities using technologies or materials developed by SUSTAIN.
The project also promoted commercial opportunities for smallholder farmers with annual sales of orange-fleshed sweet potato puree-based products estimated at more than $890,000 as a result of the project.

Perspectives from the Global South
The results of the initiative were published during the EAT Forum in Stockholm, where CGIAR scientists discussed the recommendations of the EAT-Lancet report from the perspective of developing countries.
“The SUSTAIN project showed the enormous potential for achieving both healthy and sustainable diets in developing countries using improved varieties of crops that are already widely grown,” said Simon Heck, program leader, CIP.
“Sweet potato should be included as the basis for a sustainable diet in many developing countries because it provides more calories per hectare and per growing month than all the major grain crops, while tackling a major nutrition-related health issue.”
At an EAT Forum side event, scientists highlighted that most food is grown by small-scale producers in low- and middle-income countries, where hunger and undernutrition are prevalent and where some of the largest opportunities exist for food system and dietary transformation.
“There are almost 500 million small farms that comprise close to half the world’s farmland and are home to many of the world’s most vulnerable populations,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT).
“Without access to appropriate technologies and support to sustainably intensify production, small farmers — the backbone of our global food system — will not be able to actively contribute a global food transformation.”
Matthew Morell, director general of the International Rice Research Institute (IRRI), added: “If the EAT-Lancet planetary health diet guidelines are to be truly global, they will need to be adapted to developing-world realities — such as addressing Vitamin A deficiency through bio-fortification of a range of staple crops.
“This creative approach is a strong example of how to address a devastating and persistent nutrition gap in South Asia and Africa.”

Biofortified maize and wheat can improve diets and health, new study shows
TEXCOCO, Mexico (CIMMYT) — More nutritious crop varieties developed and spread through a unique global science partnership are offering enhanced nutrition for hundreds of millions of people whose diets depend heavily on staple crops such as maize and wheat, according to a new study in the science journal Cereal Foods World.
From work begun in the late 1990s and supported by numerous national research organizations and scaling partners, more than 60 maize and wheat varieties whose grain features enhanced levels of zinc or provitamin A have been released to farmers and consumers in 19 countries of Africa, Asia, and Latin America over the last 7 years. All were developed using conventional cross-breeding.

“The varieties are spreading among smallholder farmers and households in areas where diets often lack these essential micronutrients, because people cannot afford diverse foods and depend heavily on dishes made from staple crops,” said Natalia Palacios, maize nutrition quality specialist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study.
More than 2 billion people worldwide suffer from “hidden hunger,” wherein they fail to obtain enough of such micronutrients from the foods they eat and suffer serious ailments including poor vision, vomiting, and diarrhea, especially in children, according to Wolfgang Pfeiffer, co-author of the study and head of research, development, delivery, and commercialization of biofortified crops at the CGIAR program known as “HarvestPlus.”
“Biofortification — the development of micronutrient-dense staple crops using traditional breeding and modern biotechnology — is a promising approach to improve nutrition, as part of an integrated, food systems strategy,” said Pfeiffer, noting that HarvestPlus, CIMMYT, and the International Institute of Tropical Agriculture (IITA) are catalyzing the creation and global spread of biofortified maize and wheat.
“Eating provitamin A maize has been shown to be as effective as taking Vitamin A supplements,” he explained, “and a 2018 study in India found that using zinc-biofortified wheat to prepare traditional foods can significantly improve children’s health.”
Six biofortified wheat varieties released in India and Pakistan feature grain with 6–12 parts per million more zinc than is found traditional wheat, as well as drought tolerance and resistance to locally important wheat diseases, said Velu Govindan, a breeder who leads CIMMYT’s work on biofortified wheat and co-authored the study.
“Through dozens of public–private partnerships and farmer participatory trials, we’re testing and promoting high-zinc wheat varieties in Afghanistan, Ethiopia, Nepal, Rwanda, and Zimbabwe,” Govindan said. “CIMMYT is also seeking funding to make high-zinc grain a core trait in all its breeding lines.”
Pfeiffer said that partners in this effort are promoting the full integration of biofortified maize and wheat varieties into research, policy, and food value chains. “Communications and raising awareness about biofortified crops are key to our work.”

Paswel Marenya is a Senior Scientist at the International Maize and Wheat Improvement Center (CIMMYT). He is the global coordinator of the SIMLESA project, based in Nairobi.
Marenya holds an MSc in Applied Economics and a PhD in Natural Resources Policy and Management, both from Cornell University. His research focuses on maize-based smallholder systems in eastern and southern Africa, and on the analysis of pathways and impacts of technology adoption within the framework of sustainable intensification.
He has published research on farmer policy, farmer preferences for supporting technology adoption among maize farmers in Malawi, soil quality mediated returns to fertilizer, and the macro impacts of disease tolerant varieties. He is currently working on understanding the most effective investment priorities for strengthening climate-smart agriculture in eastern and southern Africa.
Fodder for thought
A recent study shows the slow adoption of conservation agriculture practices in sub-Saharan Africa, despite their multiple benefits for smallholder farmers. In Zimbabwe, it is estimated that no more than 2.5% of cropland is cultivated under conservation agriculture principles.
One of the constraints is the lack of appropriate machinery and tools that reduce drudgery. “Addressing a wide set of complementary practices, from nutrient and weed management and judicious choice of crop varieties to labor demand, is key to making conservation agriculture profitable and feasible for a greater number of farmers,” said Christian Thierfelder, Principal Scientist at the International Maize and Wheat Improvement Center (CIMMYT).
Farmers in the district of Murehwa, in Zimbabwe’s Mashonaland East Province, have embraced sustainable farming systems. They are benefitting from higher yields and new sources of income, and they are improving soil fertility.

Cosmas and Netsai Garwe’s homestead copes well despite the erratic weather. They own a lush one-acre field of maize and well-fed livestock: 18 cows, 9 goats and 45 free-range chickens. Two years after a crop-livestock integration initiative funded by the Australian Centre for International Agricultural Research (ACIAR) ended, the family still benefits from the conservation agriculture practices they learnt.
“We were taught the value of minimum tillage using direct seeding, rotation, mulching and weeding to ensure that our maize crop thrived,” explained Cosmas Garwe. “Intercropping and crop rotation with legumes like soybean, pigeon pea and velvet beans really improved our soil,” said Netsai Garwe.
Like the Garwes, more than 2,000 farmers in Murehwa district are scaling the production of lablab and velvet beans, which implies almost complete adoption. Effective extension support, local innovation platforms, and access to profitable crop and livestock markets have been key drivers for widespread adoption.
Better soil and cash cows
Many of these smallholder farmers’ fields have been under cultivation for generations and the granitic sandy soils, predominant in the area, have become very poor in soil organic matter, a key component of soil fertility.
“Nitrogen-fixing green manure cover crops such as velvet beans, lablab and jack beans can provide an affordable way for smallholder farmers to bring back soil fertility, especially nitrogen, into the soil,” explained Thierfelder. “Once the soils become responsive to mineral fertilizer again, a combination of leguminous crop rotations, manure use and in-organic fertilizer will provide stable and sustained crop yields of maize, their main food crop, even under a changing climate.”
Starting the second year the Garwes tried conservation agriculture on a 0.4-hectare plot, their yields improved, realizing 1.2 tons. As an additional benefit, the cover crops could be used as new animal feed sources, so they could keep maize crop residues as soil cover and increase the amount of organic matter in the soils.
Adoption of green manure cover crops was not easy at first, but farmers from Murehwa quickly realized that lablab and velvet beans improved the fattening of cattle and poultry. Drying the cover crop, they were able to produce protein-rich hay bales, sought-after in winter when other fodder stocks usually run low.
Better-fed, healthier animals meant better sales, as the Garwes could now get around $1,200 for one cow. Neighboring farmers soon found this new crop-livestock system appealing and joined the initiative.

Saving for a dry day
The economic opportunities for farmers in Murehwa go beyond cow sales. In 2013, the Klein Karoo (K2) seed company offered contracts to farmers for the production of lablab seed. Suddenly the crop became highly profitable, which trigged adoption by almost all the farmers in the area.
As explained by extension officer Ngairo, “there is lablab and velvet beans grown everywhere, at homestead plots, school gardens… using ripline seeding techniques and showing the widespread adoption of conservation agriculture practices in the ward.”
Better incomes from livestock, fodder and lablab seeds had ripple effects for these Murehwa communities.

Since they adopted lablab and conservation agriculture practices in 2013, Kumbirai and Lilian Chimbadzwa transformed their asset base. They were able to complete their four-bedroom house, connect their homestead with the national electricity network and send their daughter to a nearby boarding school.
Despite prolonged dry spells during the last season and the threat of fall armyworm, these farmers have been coping much better than those practicing conventional tillage farming.
“Farmers taking up lablab and other leguminous cover crops have not only improved their incomes, but also the resilience of their farming systems,” explained Isaiah Nyagumbo, Cropping Systems Agronomist at CIMMYT. “Conservation agriculture practices such as mulching help retain soil moisture, while pests and diseases are less prominent in diversified fields planted with stress tolerant maize varieties and legume cover crops.”

For CIMMYT and other institutions willing to scale sustainable intensification practices in Africa, there is plenty to learn from the farmers in Murehwa.
New research in the district has started to test how climate-adapted push-pull systems support smallholder farmers in overcoming the invasive fall armyworm using biological means. These systems involve conservation agriculture, green manure and legume intercropping, and planting high-productivity fodders surrounding the plots. This would also reduce the reliance on pesticides, which may be harmful for humans and the environment.
Conservation agriculture works for farmers and for sustainable intensification
The International Maize and Wheat Improvement Centre (CIMMYT) and the Association for Strengthening Agricultural Research in Eastern and Southern Africa (ASARECA) gathered agriculture leaders, experts, ministers and permanent secretaries from 14 countries in the region May 2-4, 2019 in Kampala, Uganda. These experts reflected on the lessons learned from the eight year-long Sustainable Intensification of Maize and Legumes farming systems in Eastern and Southern Africa (SIMLESA) project, funded by the Australian Centre for International Agricultural Research (ACIAR).
During this regional SIMLESA policy forum, ministers of agriculture signed a joint communiqué calling for mainstreaming conservation agriculture practices and enabling sustainable intensification of African agriculture, in response to the ongoing agroecological crisis and fast-growing population.
The minister of agriculture, animal industry and fisheries of Uganda, Vincent Ssempijja, reminded that “Africa is paying a high price from widespread land degradation, and climate change is worsening the challenges smallholder farmers are facing.” Staple crop yields are lagging despite a wealth of climate-smart technologies like drought-tolerant maize varieties or conservation agriculture.
“It is time for business unusual,” urged guest speaker Kirunda Kivejinja, Uganda’s Second Deputy Prime Minister and Minister of East African Affairs.
Research conducted by CIMMYT and national partners in Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Tanzania and Uganda under the SIMLESA project provided good evidence that sustainable intensification based on conservation agriculture works — it significantly increased food crop yields, up to 38%, as well as incomes, while sustainably preserving soil health.
In Malawi, where conservation agriculture adoption rose from 2% in 2011 to 35% in the 2017/18 season, research showed increases in water infiltration compared to the conventional ridge-and-furrow system of up to 90%, while soil organic carbon content increased by 30%. This means that soil moisture is better retained after rainfall, soil is more fertile, and plants grow well and cope much better during dry spells.
The SIMLESA project revealed that many farmers involved in CIMMYT research work, like Joseph Ntirivamunda in Rwanda, were interested in shifting towards more sustainable intensification practices. However, large-scale adoption still faces many hurdles.
“You cannot eat potential,” pointed out CIMMYT scientists and SIMLESA project leader Paswel Marenya. “The promise of conservation agriculture for sustainable intensification needs to be translated into more food and incomes, for farmers to adopt it widely.”

The scale conundrum
Farmers’ linkages to markets and services are often weak, and a cautious analysis of trade-offs is necessary. For instance, more research is needed about the competing uses of crop residues for animal feed or soil cover.
Peter Horne, General Manager for ACIAR’s global country programs, explained that science has an important role in informing policy to drive this sustainable transformation. There are still important knowledge gaps to better understand what drives key sustainable farming practices. Horne advised to be more innovative than the traditional research-for-development and extension approaches, involving for instance the private sector.
Planting using a hoe requires 160 hours of labor per hectare. A two-wheel tractor equipped with a planter will do the same work in only 3 hours.
One driver of change that was stressed during the Kampala forum was the access to appropriate machinery, like the two-wheel tractor equipped with a direct planter. While hoe planting requires 160 hours of labor per hectare, the planter needs only 3 hours per hectare, enabling timely planting, a crucial factor to respond effectively to the increased vagaries of the weather and produce successful harvests. While some appropriate mechanization options are available at the pilot stage in several African countries like Ethiopia or Zimbabwe, finding the right business models for service provision for each country is key to improve access to appropriate tools and technologies for smallholder farmers. CIMMYT and ACIAR seek to provide some answers through the complementary investments in the Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project.
CASI can be scaled but requires tailoring sustainable intensification agronomic advices adapted to local environment and farming systems. Agricultural innovation platforms like the Mwanga mechanization youth group in Zimbabwe are one way to co-create solutions and opportunities between specific value chain actors, addressing some of the constraints farmers may face while implementing conservation agriculture practices.
Providing market incentives for farmers has been one challenging aspect, which may be overcome through public-private partnerships. Kilimo Trust presented a new consortium model to drive sustainable intensification through a market pull, linking smallholder farmers with food processors or aggregators.
“SIMLESA, as a long-term ambitious research program, has delivered remarkable results in diverse farming contexts, and conservation agriculture for sustainable intensification now has a more compelling case,” said Eric Huttner, ACIAR research program manager. “We should not ignore the complexity of conservation agriculture adoption, as shifting to new farming practices brings practical changes and potential risks for farmers, alongside benefits,” he added. As an immediate step, Huttner suggested research to define who in the public and private sectors is investing and for what purpose — for example, access to seed or machinery. Governments will also need further technical support to determine exactly how to mainstream conservation agriculture in future agricultural policy conversations, plans and budgets.
“Looking at SIMLESA’s evidence, we can say that conservation agriculture works for our farmers,” concluded Josefa Leonel Correia Sacko, Commissioner for Rural Economy and Agriculture of the African Union. During the next African Union Specialized Technical Committee in October 2019, she will propose a new initiative, scaling conservation agriculture for sustainable intensification across Africa “to protect our soils and feed our people sustainably.”

Shifting to a demand-led maize improvement agenda
Partners of the Stress Tolerant Maize for Africa (STMA) project held their annual meeting May 7–9, 2019, in Lusaka, Zambia, to review the achievements of the past year and to discuss the priorities going forward. Launched in 2016, the STMA project aims to develop multiple stress-tolerant maize varieties for diverse agro-ecologies in sub-Saharan Africa, increase genetic gains for key traits preferred by the smallholders, and make these improved seeds available at scale in the target countries in partnership with local public and private seed sector partners.
The project, funded by the Bill & Melinda Gates Foundation and the United States Agency for International Development (USAID), is led by the International Maize and Wheat Improvement Center (CIMMYT), and implemented together with the International Institute for Tropical Agriculture (IITA), national agricultural research systems and seed company partners in 13 countries in sub-Saharan Africa.
The meeting was officially opened by the Deputy Director of the Zambia Agriculture Research Institute (ZARI), Monde Zulu. “Maize in Africa faces numerous challenges such as drought, heat, pests and disease. Thankfully, these challenges can be addressed through research. I would like to take this opportunity to thank CIMMYT and IITA. Your presence here is a testament of your commitment to improve the livelihoods of farmers in sub-Saharan Africa,” she said.
The International Maize and Wheat Improvement Center (CIMMYT) and its partners are working together in the fight against challenges such as drought, maize lethal necrosis and fall armyworm. The STMA project applies innovative technologies such as high-throughput phenotyping, doubled haploids, marker-assisted breeding and intensive germplasm screening to develop improved stress-tolerant maize varieties for smallholder farmers. The project team is also strengthening maize seed systems in sub-Saharan Africa through public-private partnerships.
The efforts are paying off: in 2018, 3.5 million smallholder farmers planted stress-tolerant maize varieties in 10 African countries.

Yielding results
CIMMYT researcher and STMA project leader Cosmos Magorokosho reminded the importance of maize in the region. “Maize is grown on over 35 million hectares in sub-Saharan Africa, and more than 208 million farmers depend on it as a staple crop. However, average maize yields in sub-Saharan Africa are among the lowest in the world.” Magorokosho pointed out that the improved maize varieties developed through the project “provide not only increased yields but also yield stability even under challenging conditions like drought, poor soil fertility, pests and diseases.”
“STMA has proved that it is possible to combine multiple stress tolerance and still get good yields,” explained B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE). “One of the important aspects of STMA are the partnerships which have only grown stronger through the years. We are the proud partners of national agricultural research systems and over 100 seed companies across sub-Saharan Africa.”
Keynote speaker Hambulo Ngoma of the Indaba Agricultural Policy Research Institute (IAPRI) addressed the current situation of maize in Zambia, where farmers are currently reeling from recent drought. “Maize is grown by 89% of smallholder farmers in Zambia, on 54% of the country’s cultivable land, but productivity remains low. This problem will be exacerbated by expected population growth, as the population of Zambia is projected to grow from over 17 million to 42 million by 2050,” he said.

Down to business
On May 8, participants visited three partner local seed companies to learn more about the opportunities and challenges of producing improved maize seed for smallholder farmers.
Afriseed CEO Stephanie Angomwile discussed her business strategy and passion for agriculture with participants. She expressed her gratitude for the support CIMMYT has provided to the company, including access to drought-tolerant maize varieties as well as capacity development opportunities for her staff.
Bhola Nath Verma, principal crop breeder at Zamseed, explained how climate change has a visible impact on the Zambian maize sector, as the main maize growing basket moved 500 km North due to increased drought. Verma deeply values the partnership with the STMA project, as he can source drought-tolerant breeding materials from CIMMYT and IITA, allowing him to develop early-maturing improved maize varieties that escape drought and bring much needed yield stability to farmers in Angola, Botswana, the Democratic Republic of the Congo, Tanzania and Zambia.
At QualiBasic Seed, STMA partners were given the opportunity to learn and ask questions about the company’s operations, including the seed multiplication process in Zambia and the importance of high-quality, genetically pure foundation seed for seed companies.

Young ideas
The meeting concluded with an awards ceremony for the winners of the 2019 MAIZE Youth Innovators Awards – Africa, established by MAIZE in collaboration with the Young Professionals for Agricultural Development (YPARD). These awards recognize the contributions of young women and men under 35 who are implementing innovations in African maize-based agri-food systems, including research-for-development, seed systems, agribusiness, and sustainable intensification. This is the second year of the MAIZE Youth Awards, and the first time it has been held in Africa. Winners include Hildegarde Dukunde of Rwanda and Mila Lokwa Giresse of the Democratic Republic of the Congo in the change agent category, Admire Shayanowako of the Republic of South Africa and Ismael Mayanja of Uganda in the research category, and Blessings Likagwa of Malawi in the farmer category.

MARPLE team recognized for international impact

The research team behind the MARPLE (Mobile And Real-time PLant disEase) diagnostic kit won the International Impact category of the Innovator of the Year 2019 Awards, sponsored by the United Kingdom’s Biotechnology and Biological Sciences Research Council (BBSRC).
The team — Diane Saunders of the John Innes Centre (JIC), Dave Hodson of the International Maize and Wheat Improvement Center (CIMMYT) and Tadessa Daba of the Ethiopian Institute for Agricultural Research (EIAR) — was presented with the award at an event at the London Science Museum on May 15, 2019. In the audience were leading figures from the worlds of investment, industry, government, charity and academia, including the U.K.’s Minister of State for Universities, Science, Research and Innovation, Chris Skidmore.
The BBSRC Innovator of the Year awards, now in their 11th year, recognize and support individuals or teams who have taken discoveries in bioscience and translated them to deliver impact. Reflecting the breadth of research that BBSRC supports, they are awarded in four categories of impact: commercial, societal, international and early career. Daba, Hodson and Saunders were among a select group of 12 finalists competing for the four prestigious awards. In addition to international recognition, they received £10,000 (about $13,000).
“I am delighted that this work has been recognized,” Hodson said. “Wheat rusts are a global threat to agriculture and to the livelihoods of farmers in developing countries such as Ethiopia. MARPLE diagnostics puts state-of-the-art, rapid diagnostic results in the hands of those best placed to respond: researchers on the ground, local government and farmers.”
On-the-ground diagnostics
The MARPLE diagnostic kit is the first operational system in the world using nanopore sequence technology for rapid diagnostics and surveillance of complex fungal pathogens in the field.
In its initial work in Ethiopia, the suitcase-sized field test kit has positioned the country — one of the region’s top wheat producers — as a world leader in pathogen diagnostics and forecasting. Generating results within 48 hours of field sampling, the kit represents a revolution in plant disease diagnostics. Its use will have far-reaching implications for how plant health threats are identified and tracked into the future.
MARPLE is designed to run at a field site without constant electricity and with the varying temperatures of the field.
“This means we can truly take the lab to the field,” explained Saunders. “Perhaps more importantly though, it means that smaller, less-resourced labs can drive their own research without having to rely on a handful of large, well-resourced labs and sophisticated expertise in different countries.”
In a recent interview with JIC, EIAR Director Tadessa Daba said, “we want to see this project being used on the ground, to show farmers and the nation this technology works.”

Development of the MARPLE diagnostic kit was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the CGIAR Platform for Big Data in Agriculture’s Inspire Challenge. Continued support is also provided by the BBSRC’s Excellence with Impact Award to the John Innes Centre and the Delivering Genetic Gain in Wheat project, led by Cornell University and funded by the UK’s Department for International Development (DFID) and the Bill & Melinda Gates Foundation.
