It is no secret that Africa is urbanizing at breakneck speed. Consider Lagos. In 1950 the Nigerian city boasted a population of a few hundred thousand. Today that number has soared to around 14 million. It is estimated that by 2025 half of Africaâs population will live in urban areas.
This demographic transformation has had dramatic consequences for human health and nutrition. Urban dwellers are far more likely to rely on cheap highly-processed foods, which are shelf-stable but poor on nutrients.
These statistics, presented by moderator Betty Kibaara, Director of the Food Initiative at The Rockefeller Foundation, framed the 2020 African Green Revolution Forumâs policy symposium on âAdvancing Gender and Nutrition.â The forum comprised two tracks. One focused on addressing the needs of nutritionally vulnerable urban consumers, particularly women; the other on gender-based financing in the African agri-food system
Speaking in the first track, Natalia Palacios, maize quality specialist at the International Maize and Wheat Improvement Center (CIMMYT), underlined the enormity of the challenge. âWe need to provide affordable, nutritious diets … within planetary boundaries,â she said.
Many of the panelists pointed out further dimensions of the challenge â from evidence deficits around the continentâs urban populations to the amplifying effects of the COVID-19 crisis. Palacios stressed that the bedrock of any response must be effective partnerships between governments, companies and non-profit actors working in this area.
âThe really important thing is to start working together,â she said, âto start developing the strategies together instead of providing things or demanding things.â Speaking to the role of organizations like CIMMYT, Palacios highlighted the need to work closely with the private sector to understand the demand for agricultural raw materials that can be converted into nutritious diets.
Rich nutrition within reach
Palaciosâ most recent research efforts focus on precisely this question. She and a team of researchers, including CIMMYT senior scientist Santiago Lopez-Ridaura, explored how various innovations in maize production have improved the macro- and micro-nutrient content of the grain and led to healthier maize-based agri-food systems.
CIMMYT, HarvestPlus and the International Institute of Tropical Agriculture (IITA), together with several stakeholders, have been deeply involved in work to improve the nutritional quality of staple-dependent food systems. In partnership with a broad network of national and private-sector partners, they have released over 60 improved maize and wheat varieties fortified with zinc or provitamin A in 19 countries.

The International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) recently launched a project that aims to research the drivers and barriers to adoption of conservation agriculture in southern Africa, and to develop strategies for achieving adoption and impact at scale.
The project, Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA), will apply social and scaling science to understand the biophysical, socioeconomic, institutional, and policy drivers and barriers to the adoption of conservation agriculture technologies and practices.
The ACASA project is supported by the Norwegian Agency for Development Cooperation (Norad) and will be implemented in Malawi, Zambia, and Zimbabwe in collaboration with partners and farmers in the region.
The project was officially launched online on September 16, 2020. Zambiaâs Minister of Agriculture, Michael Katambo, noted that it is a timely intervention, as the livelihoods and food security of smallholder farmers in southern Africa are increasingly being threatened by climate change and variability, which have led to a steady decline in the production of food staples and an increase in the number of food and nutrition-insecure people.
âIt is now clear that current productivity and production levels cannot be expected to meet our requirements for food and nutrition security,â Katambo said in a speech read on his behalf by Moses Mwale, Director of the Department of Agriculture. âConservation agriculture has a proven potential to increase and stabilize crop yields, and to support sustainable and resilient production systems and rural livelihoods.â
Proven benefits
Conservation agriculture â a farming system that promotes minimum soil disturbance, permanent soil cover and diversification of plant species â can efficiently increase agricultural productivity while reducing land degradation and improving soil health for more productive, profitable, and sustainable farming.
Substantial on-farm evidence has been generated on the agronomic and economic benefits of conservation agriculture, first introduced in the 1970s in South Africa. Consequently, donors and governments have made a lot of investments to promote and scale conservation agriculture technologies and practices among smallholder farmers in the region. Despite all these efforts, however, the adoption rate among smallholder farmers remains low.
“We should not let the low adoption of conservation agriculture discourage us. Let us use this opportunity to reflect and identify the missing link and come up with more sustainable solutions to the problem,” said the IITA Director for Southern Africa, David Chikoye.
âAlthough adoption of improved practices by most resource-poor farmers is primarily determined by the potential immediate benefits on crop yields, profits, risk, and livelihoods, there are a number of biophysical, socioeconomic, institutional, and policy factors that promote or hinder adoption of conservation agriculture. The project, therefore, aims to identify the adoption drivers and barriers, and to develop pathways and strategies for inclusive scaling of conservation agriculture practices,â said  Arega Alene, Agricultural Economist at IITA and leader of the ACASA project.
Christian Thierfelder, Principal  Cropping Systems Agronomist at CIMMYT, highlighted some of the bottlenecks for conservation agriculture adoption, noting they were linked more to socioeconomic and cultural factors rather than biophysical. “Conservation agriculture is a viable and proven climate-smart farming system. Future research efforts should go towards understanding farmers’ decision-making and behavioral change, as well as profitability,” Thierfelder said.
Other key partners include the Food and Agriculture Organization of the United Nations (FAO), the African Conservation Tillage Network (ACT) and Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA).
The project launch was attended by policymakers, donors, members of national and regional conservation agriculture taskforces, national and international research institutions, universities, international development institutions, private seed companies, non-governmental organizations, and farmer organizations.

About IITA:
The International Institute of Tropical Agriculture (IITA) is a not-for-profit institution that generates agricultural innovations to meet Africaâs most pressing challenges of hunger, malnutrition, poverty, and natural resource degradation. Working with various partners across sub-Saharan Africa, we improve livelihoods, enhance food and nutrition security, increase employment, and preserve natural resource integrity. IITA is a member of CGIAR, a global agriculture research partnership for a food-secure future.
The CGIAR Research Program on Maize (MAIZE) is proud to release its 2019 Annual Report.
Around the world, the COVID-19 crisis has emphasized the need to strengthen food systems while improving the food security and livelihoods for the most vulnerable, especially the resource-constrained smallholder farmers.
In 2019 MAIZE and its partners made great advances in the development of improved stress-tolerant maize varieties, continued their battle against fall armyworm in both Africa and Asia, and maintained their focus on sustainable intensification of maize-based cropping systems in sub-Saharan Africa, South Asia and Latin America where maize plays a critical role in food and nutritional security, income and livelihoods of millions of resource-constrained smallholders and consumers. We look forward to continued productive collaborations as we transition with our partners into an integrated, inclusive One CGIAR designed to meet the UN Sustainable Development Goals.
Led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Institute of Tropical Agriculture (IITA) as its main CGIAR Consortium partner, MAIZE focuses on increasing maize production for the 900 million poor consumers for whom maize is a staple food in Africa, South Asia and Latin America.
Stakeholders in the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project have pledged to strengthen efforts to deliver desirable stress tolerant, nutritious and high-yielding maize and wheat varieties to smallholder farmers in a much shorter time. The alliance, comprising funders, national agricultural research systems (NARS), private seed companies, non-governmental organizations, the International Maize and Wheat Improvement Center (CIMMYT) and, for the maize component the International Institute for Tropical Agriculture (IITA), made these assurances during virtual events held in July and August 2020, marking the inception of the 5-year AGG project.
The initiative seeks to fast-track the development of higher-yielding, climate resilient, demand-driven, gender-responsive and nutritious seed varieties for maize and wheat, two of the worldâs most important staple crops. The project is funded by the Bill & Melinda Gates Foundation, the Foreign, Commonwealth & Development Office (FCDO), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).
Tackling current and emerging threats
Jeff Rosichan, scientific program director of the Foundation for Food and Agricultural Research (FFAR), acknowledged the significant and ambitious aim of the project in tackling the challenges facing maize and wheat currently and in the future. âWe are seeing the emergence of new pests and pathogens and viral diseases like never before. A lot of the work of this project is going to help us to tackle such challenges and to be better prepared to tackle emerging threats,â he said.
AGG builds on gains made in previous initiatives including Drought Tolerant Maize for Africa (DTMA), Improved Maize for African Soils (IMAS), Water Efficient Maize for Africa (WEMA), Stress Tolerant Maize for Africa (STMA) and Delivering Genetic Gain in Wheat (DGGW), with support from partners in 17 target countries in sub-Saharan Africa (SSA) and South Asia.
Hailu Wordofa, agricultural technology specialist at the USAID Bureau for Resilience and Food Security, underscored his expectation for CIMMYTâs global breeding program to use optimal breeding approaches and develop strong collaborative relationships with NARS partners, âfrom the development of product profiles to breeding, field trials and line advancement.â
Similarly, Gary Atlin, senior program officer at the Bill & Melinda Gates Foundation lauded the move toward stronger partnerships and greater emphasis on the CIMMYT and IITA breeding programs. âThe technical capacity of partners has increased through the years. It is prudent to ensure that national partnerships continue. It is always a challenging environment, this time multiplied by the COVID-19 crisis, but through this collaboration, there is a greater scope to strengthen such partnerships even more,â he said.

Symbiotic partnerships with great impact
âFrom the NARS perspective, we are committed to doing our part as primary partners to deliver the right seed to the farmers,â said Godfrey Asea, director of the National Crops Resources Research Institute at the National Agriculture Research Organization (NARO), Uganda. âWe see an opportunity to review and to use a lot of previous historical data, both in-country and regionally and to continue making improved decisions. We also reiterate our commitment and support to continuously make improvement plans in our breeding programs.â
Martin Kropff, director general of CIMMYT, recognized the tremendous impact arising from the longstanding cooperation between CIMMYTâs maize and wheat programs and national programs in countries where CIMMYT works. âA wheat study in Ethiopia showed that 90% of all the wheat grown in the country is CIMMYT-related, while an impact study for the maize program shows that 50% of the maize varieties in Africa are CIMMYT-derived. We are very proud of that â not for ourselves but for the people that we work for, the hundreds of millions of poor people and smallholder farmers who really rely on wheat and maize for their living and for their incomes,â he said.
Founder and Chief Executive Officer of East Africa-based Western Seed Company Saleem Esmail expressed optimism at the opportunities the project offers to improve livelihoods of beneficiaries. âI believe we can do this by sharing experiences and by leveraging on the impacts that this project is going to bring, from new technologies to new science approaches, particularly those that help save costs of seed production.â
He, however, observed that while the target of fast-tracking varietal turnover was great, it was a tough call, too, âbecause farmers are very risk averse and to change their habits requires a great deal of effort.â
On his part, director of Crop Research at the Oromia Agricultural Research Institute (OARI) in Ethiopia Tesfaye Letta revealed that from collaborative research work undertaken with CIMMYT, the institute has had access to better-quality varieties especially for wheat (bread and durum). These have helped millions of farmers to improve their productivity even as Ethiopia aims for wheat self-sufficiency by expanding wheat production under irrigation.
âWe expect more support, from identifying wheat germplasm suitable for irrigation, developing disease resistant varieties and multiplying a sufficient quantity of early generation seed, to applying appropriate agronomic practices for yield improvement and organizing exposure field visits for farmers and experts,â he said.
Challenges and opportunities in a time of crisis
Alan Tollervey, head of agriculture research at Foreign, Commonwealth and Development Office (FCDO) and the UK representative to the CGIAR System Council, emphasized the need for continued investment in agricultural research to build a resilient food system that can cope with the demands and pressures of the coming decades. This way, organizations such as CIMMYT and its partners can adequately deliver products that are relevant not only to the immediate demands of poor farmers in developing countries â and the global demand for food generally â but also to address foreseen threats.
âWe are at a time of intense pressure on budgets, and that is when projects are most successful, most relevant to the objectives of any organization, and most able to demonstrate a track record of delivery. CIMMYT has a long track history of being able to respond to rapidly emerging threats,â he said.
Felister Makini, the deputy director general for crops at the Kenya Agricultural Research Organization (KALRO) lauded the fact that AGG not only brings together maize and wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, âwhich will be crucial to our envisioned strategy to achieve socioeconomic change.â
Zambia Agriculture Research Organization (ZARI) maize breeder Mwansa Kabamba noted that the inclusion of extension workers will help to get buy-in from farmers especially as far as helping with adoption of the improved varieties is concerned.
In its lifecycle, the AGG project aims to reduce the breeding cycles for both maize and wheat from 5-7 years currently to 3-4 years. By 2024, at least 150,000 metric tons of certified maize seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares and benefit 64 million people. It also seeks to serve over 30 million households engaged in wheat farming the target countries.

Seed systems are complex and dynamic, involving diverse, interdisciplinary actors. Women play an important role in the seed value chain, although underlying social and cultural norms can impact their equal participation. Gender-sensitive seed systems will create more opportunities for women and increase food security.
The International Maize and Wheat Improvement Center (CIMMYT) convened a multi-stakeholder technical workshop titled, âGender dynamics in seed systems in sub-Saharan Africa and worldwide lessonsâ on December 2, 2019, in Nairobi, Kenya. Researchers and development practitioners operating in the nexus of gender and seed systems shared lessons learned and research findings to identify knowledge gaps and exchange ideas on promising â and implementable â interventions and approaches that expand opportunities for women in the seed sector.
A new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG), seeks to achieve these results by speeding up genetic gains in maize and wheat breeding to deliver improved, stress resilient, nutritious seed to smallholders in 13 countries in sub-Saharan Africa (SSA) and four in South Asia. The 5-year AGG project is funded by the Bill & Melinda Gates Foundation, the UK Department for International Development (DFID) and the U.S. Agency for International Development (USAID).

Striga, an invasive parasitic weed with purple-colored flowers, looks striking and harmless. But, beyond that mark of beauty, is a nutrient-sucking monster that stunts crops such as maize and sorghum, leaving affected farmers counting losses.
Witchweed thrives in poor soils with low rainfall conditions. It is prevalent in farming systems with poor crop management practices and in communities where farmers use minimal or no fertilizer. Once maize begins germinating in Striga-prevalent soil, it stimulates Striga seeds to germinate. Striga then attaches to the roots of the host plant, sapping nutrients from the plant, leading to stunting. The potential yield loss can reach up to 100%. Some farmers attempt to uproot it once they notice it germinating alongside their maize plantation, but this is often too late because damage is done as soon as the parasite attaches to the maize roots. When mature, the weed deposits tens of thousands of tiny seeds into the soil. This makes it very difficult for farmers to get rid of it.
To tackle this challenge, farmers need to apply inorganic fertilizer, which is not always affordable, or animal manure to enrich the soil before planting. They are also advised by researchers and extensionists to practice crop rotation or intercropping with legumes such as beans, soybean or groundnuts that restrict Strigaâs germination. Â In the Assessment of Management Options on Striga Infestation and Maize Grain Yield in Kenya, for example, researchers recommend that Striga control measures include a combination of herbicide-resistant or maize varieties with native genetic resistance intercropped with legumes.
Nevertheless, while a few control measures have been moderately successful, the problem still persists, especially in western Kenya, eastern Uganda and lake zone of Tanzania, where farmers have frequently voiced their frustrations at the ubiquity of this invasive weed.
âWhile crop rotation with crops such as soybean or beans may break the cycle of Striga, its seed can stay in the soil and remain viable for up to 10 years,â says Dan Makumbi, a maize breeder with the International Maize and Wheat Improvement Center (CIMMYT), who is leading research efforts against the witchweed.

A blow to optimal yield potential
Maize is a staple crop that is predominantly cultivated by smallholder farmers in western Kenya and the lake region. It is an important source of food security and livelihoods of millions of people in the region, but constraints such as Striga prevent farmers from obtaining the cropâs ideal potential.
âThe yield loss would have been adequate to cover my familyâs food requirements for a year,â Naliaka said. âFrom two farming seasons, I could harvest a sufficient quantity of maize and sell some surplus to pay my childrenâs school fees. With the Striga menace, all that is but a dream.â
Just like Naliaka, Norah Kayugi, a 40-year-old widowed mother of six children from Siaya County in Kenya, has seen her maize production fall to less than 8 bags of 90kgs per acre. In normal circumstances, they would obtain at least 16 bags of maize per acre. The significant yield loss sets back many affected households in a big way, as they experience food shortage only a few months after harvest. Some divert their reduced incomes for food purchases, possibly leaving other priorities such as health and education of their children unattended.
Kayugi, who has been a farmer since 1997, now takes on casual jobs to supplement her farming in order to support her family, being the sole breadwinner following her husbandâs demise years ago. âI plant vegetables, beans and maize to sustain my family. My one-acre farm yields about 10 bags of 90ks each. But I know for sure that were it not for this weed, the yield potential could reach 30 bags of 90kgs each per acre.â

Standing up to multiple farming stresses
These smallholders, like their counterparts elsewhere in sub-Saharan Africa, already face other farming challenges, including climate change-induced droughts, pests such as the fall armyworm, diseases like maize lethal necrosis (MLN), and declining soil fertility, among others. While CIMMYT has registered breakthroughs in developing maize varieties that tolerate such stresses, on-going efforts against Striga are also taking shape, challenges notwithstanding.
The development and deployment of the imazapyr-resistant (IR) maize has been one such instance of effective Striga control. With this method, herbicide-resistant maize seeds are coated with herbicide. The seed germinates and absorbs some of the herbicide used to coat it. The germinating maize stimulates Striga to germinate and as it attaches to the maize root, it is killed before it can cause any damage. Despite its effectiveness, sustaining this technology presented a major challenge to seed companies.
âIt was costly for seed companies, as they needed to establish and sustain the operation of separate seed treatment units dedicated to production of the herbicide-coated maize seed. Once you establish a line to dress the seed with the chemical, you cannot use it to treat any other seeds as the chemical will destroy them,â said Makumbi.
Seed companies â like NASECO in Uganda, Kenya Seed Company in Kenya, Western Seed Company and FreshCo in Kenya, and Meru Agro in Tanzania â obtained financial and technical support from a partnership initiative coordinated by African Agricultural Technology Foundation (AATF) and backed by CIMMYT to scale commercialisation of StrigAwayTM maize in East Africa. The initiative was funded by USAIDâs Feed the Future Partnering for Innovation program through Fintrac and it supported the seed companies to establish seed treatment facilities to handle herbicide resistant maize. This allowed each of the companies to have a fully dedicated facility for herbicide resistant maize seed processing. âRight now, herbicide resistant maize hybrid seed is available on the market in Kenya, Tanzania and Uganda,â Makumbi said.

Native hope
In the past few years, Makumbi and his team, in collaboration with the International Institute for Tropical Agriculture (IITA) and the Kenya Agricultural and Livestock Research Organization (KALRO), have redirected their efforts towards breeding for native genetic resistance to Striga. This means developing seeds which are naturally resistant to Striga, reducing the need for herbicides. The early indication is that there are several parental lines showing potential to tolerate or resist Striga, and these are being used to develop hybrids. The hybrids, which offer multiple benefits for farmers, are under wide scale testing in Kenya.
âIn our tests, we are not only looking at Striga resistance alone but also other important traits such as good yield under optimal conditions, drought stress and low soil fertility, resistance to major foliar diseases including gray leaf spot, Turcicum leaf blight, maize streak virus and ear rots,â Makumbi noted.
As these breeding efforts continue, there is light at the end of the tunnel. The hope of farmers taking back full control of their maize farms from Strigaâs âbewitching waysâ in the near future remains alive.

As plant pests and diseases continue to evolve, with stresses like drought and heat intensifying, a major priority for breeders and partners is developing better stress tolerant and higher yielding varieties faster and more cost effectively.
A new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG), seeks to achieve these results by speeding up genetic gains in maize and wheat breeding to deliver improved, stress resilient, nutritious seed to smallholders in 13 countries in sub-Saharan Africa (SSA) and four in South Asia. The 5-year AGG project is funded by the Bill & Melinda Gates Foundation, the UK Department for International Development (DFID), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).
The maize component of the project brings together diverse partners, including the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA) as co-implementers; national agricultural research systems (NARS); and small and medium-sized (SME) seed companies.
Ambitious targets
At the inception meeting of the maize component of AGG on July 10, 2020, project leaders, partners and funders lauded the ambitious targets that aim to bolster the resilience and better the livelihoods, food and nutritional security of millions of smallholder farmers in SSA. At least 150,000 metric tons of certified seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares by 2024 and benefiting 64 million people.
âWe are developing climate resilient, nutritious, efficient, productive maize varieties for the farming community in sub-Saharan Africa. We will continue to work closely with our partners to develop product profiles, which are centered on the varieties that are really needed,â said CIMMYT Interim Deputy Director for Research Kevin Pixley.
AGG draws a solid foundation from previous projects such as Drought Tolerant Maize for Africa (DTMA), Improved Maize for Africa Soils (IMAS), Water Efficient Maize for Africa (WEMA) and Stress Tolerant Maize for Africa (STMA). Several high-yielding maize varieties that tolerate and/or resist diseases such as maize lethal necrosis (MLN), gray leaf spot (GLS), northern corn leaf blight, maize streak virus (MSV), turcicum leaf blight (TLB) and are drought-tolerant (DT), were developed and released to farmers across SSA. Varieties with nutritional traits such as nitrogen use efficiency (NUE) and quality protein maize (QPM) were also developed in the preceding initiatives.

A matter of âlife or deathâ
âWhen farmers are confronted by aggressive farming challenges, they want products that address those challenges at the earliest opportunity. Waiting for years could mean the difference between life and death,â remarked David Chikoye, the director of Southern Africa Hub at IITA.
A key focus of AGG is to incorporate gender-intentionality – special attention to the needs of women farmers and consumers – from the traits bred into new varieties, through the communication and technology deployment strategies.
âAGG provides an excellent opportunity to reorient our maize breeding, seed scaling and delivery strategies for greater impact on the livelihoods of smallholder farmers, especially women and the disadvantaged communities that are not well reached so far,â said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize. âOur vision is to accelerate genetic gains to 1.5-2 percent annually across different breeding pipelines in the 13 participating countries in SSA and to reach over 10 million households with improved varieties.â
AGG will strengthen the capacity of partners to achieve and sustain accelerated variety replacement — or turnover — and increase genetic gains in farmersâ fields.
Old vs new
Many improved varieties have been released in the past decade. However, the turnover of old and obsolete varieties with new and improved ones is not happening as quickly as anticipated.
âWe are producing good products and getting them out, but not at the speed that farmers need. How do we make it possible and profitable for seed companies to quickly introduce new hybrids?â posed Gary Atlin, program officer at the Bill & Melinda Gates Foundation. âWe need to move towards a breeding and seed system where we know that we can develop a new product in 4 or 5 years and then get it to the farmers much more quickly. This is a complex problem.â
To enhance AGGâs ability to identify new products that perform well for farmers under their challenging circumstances, on-farm testing will be scaled up significantly.
Guest of honor, Ethiopiaâs Minister of State for Agriculture Mandefro Nigussie, lauded CIMMYTâs support in improving the resilience and productivity of maize and wheat in the country. He observed that this has helped improve maize productivity in Ethiopia from around 2 tons/ha to about 4 tons/ha over the past two decades.
âWe consider such a huge accomplishment as a combination of efforts in germplasm development and breeding efforts of CIMMYT and the Ethiopian national programs. That partnership will flourish further in this new project,â he said.
Seed companies play a crucial role in delivering improved seed varieties to smallholder farmers. Masindi Seed Company Limited, located in Ugandaâs mid-western region, is one such enterprise.
It traces its beginnings back to the Masindi District Farmers Association (MADFA) more than a decade ago. At the time, the association, which was comprised of about 9,000 farmers, was organized into a seed out-grower scheme of the then government-led Uganda Seed Project.
While its members were well trained, operated professionally and did their out-grower work diligently, the association faced one major challenge that almost broke it up: the âcertifiedâ seed they bought from some seed firms could not germinate.
âAt the time that we were operating solely as a farmersâ association, we did our best to grow maize seed for various seed companies who would then go on to produce and supply certified seed,â said Eugene Lusige, Masindi Seed general manager. âBut we soon realized that a lot of the certified seed that we bought was of very poor quality due to their inability to germinate or because of low germination rates. This caused our farmers huge losses. We instead took this situation as a blessing in disguise, venturing into the certified seed production business based on our experience.â
Such turn of events meant the association had to not only produce the right seed, at the right price, at the right time and with the attributes their farmers desired, but also had to provide an opportunity to generate income for its members. By establishing Masindi Seed Company in 2009, the association members fulfilled their dream and ended up killing several birds with one stone by addressing multiple seed production challenges.
Over the past few decades, the liberalization of the Ugandan seed industry has seen it morph from government control, largely with the support of public sector research institutions, to increased private sector participation. This saw a resurgence in local and foreign-based seed firms involved in seed production, processing and marketing, which significantly contributed to increased delivery of certified seed to farming communities.

Reliable and beneficial partnerships
As one of the enterprises operating in the formal seed market, Masindi Seed has grown from strength to strength over the years, working closely with the National Crops Resources Research Institute (NaCRRI) of the National Agricultural Research Organization (NARO) in Uganda. The Longe 5D, an open pollinated variety (OPV) â an improved version of the Longe 5 â was the first certified seed that ushered them into the seed production and marketing landscape in 2009. The company accessed hybrids and parental materials from NARO, which works very closely with the International Maize and Wheat Improvement Center (CIMMYT) to obtain improved stress tolerant maize.
âBesides the parental materials we receive from CIMMYT through NARO, we are trained on best practices in quality seed production, and receive materials and financial support for some of our operations,â Lusige said.
In the first year, the company produced about 120-150 tons of the Longe 5D variety, which has remained their flagship product over the past decade. Currently, the variety has up to 65 % share of the companyâs annual seed production capacity, which stands at about 1,200 tons. The annual capacity is poised to reach 2,400 by 2025 due to growing demand from farmers. The first stress tolerant hybrid, UH5053, was introduced in 2013 and two more hybrids have since gone into commercial production.
âThe hybrids have much higher yield than the OPVs and other varieties in the market in this region. They are stress tolerant and some are early maturing,â Lusige said âBut, the advantage with the Longe 5D is that it is much cheaper, with a seed packet going for less than its hybrid equivalent. So, it is best suited for the resource-constrained farmers who may not have the funds to buy artificial fertilizer. However, under normal farmer conditions, it yields between 1.5-1.8 tons per acre compared to a hybrid that can produce about 3 tons or more.â
The Longe 5D is also a quality protein maize (QPM) variety, which combats hidden hunger by providing essential amino acids that children and lactating mothers need, according to Godfrey Asea, director of the National Crops Resources Research Institute at NARO.
âOne of the initiatives we have been working on is nutritious maize, with some of the OPVs that we have released in the past being QPM varieties,â Asea said. âWe are thinking of integrating more nutrient qualities such as vitamin âAâ in new varieties, some of which are in the release pipeline. We have also acquired genetic resources that are rich in zinc. QPM varieties, as well as varieties that are biofortified with vitamin A and zinc are very important in improving household nutrition in the future for resource-constrained maize-dependent communities.â
To make farmers aware of available seed and important attributes, marketing and promotional activities through radio, flyers, banners, field days and on-farm demonstrations come in handy. For some newer varieties, the company goes as far as issuing small seed packs to farmers so they can see for themselves how the variety performs.

From a regional outfit to the national stage
In the beginning, growth was slow for Masindi Seed due to capacity and financial constraints to sustain promotional activities. Around 2013 and 2015, the company received support from the Alliance for a Green Revolution in Africa (AGRA) to scale-up its marketing and promotional efforts, which greatly enhanced Masindi Seedâs capacity and visibility. From then on, Masindi Seed went from being just a small regional-focused outfit to a nation-wide seed firm, marketing seed as far as northern and eastern Uganda.
By working closely with farmers, Masindi Seed Company puts itself at a strategic position to understand farmersâ preferred traits better. They have found that farmers prefer traits that allow them to earn more, such as higher yield, which allows them to harvest much more maize and sell the surplus for much-needed income.

Seed that farmers can trust
Alinda Sarah, who doubles up as both a contract farmer for Masindi Seed and a large-scale grower for maize grain, agrees that obtaining the right seed that is guaranteed to germinate and offers a higher yield is a major boost to her trade.
âAll I require is seed that I trust to have the attributes I want. What works for me is the seed that offers a higher yield, and can tolerate common stresses including drought, diseases and pests. This way, I can sustain my farming business,â she says.
The second attribute the farmers keep mentioning to Masindi agricultural extensionists is the maturity period, with farmers inclined to prefer faster maturing varieties, such as varieties that mature in 90 days. Ultimately, beyond some of these desirable and beneficial traits, the farmer is, before anything else, interested in the germinability of the seed they buy.
âBy confirming the attributes that we tell them regarding our varieties with what they see at demo farms, the farmers trust us more,â Lusige said. âTrust is good for a business like ours and we try our best to preserve it. In the past, we have seen how some companies who lost the trust of their customers quickly went out of business.â
âBesides offering improved seed to farmers, we encourage our partner seed companies to support and teach the farmers good agronomic practices such as proper fertilizer requirements and application rates, early planting, appropriate spacing, weed control, integrated pest management and intercropping with legumes,â said Daniel Bomet, maize breeder at NARO.

Developed by CABI in partnership with leading researchers and institutions, the portal is a free-to-access platform that enables the sharing of research data, insights and outputs, and includes a range of key features such as posting research updates, identifying collaborators, and posting questions to the community.
The Research Collaboration Portal is the official platform for the Fall Armyworm R4D International Consortium. B. M. Prasanna, Director of CIMMYTâs Global Maize Program and the CGIAR Research Program on Maize (MAIZE) and co-chair of the portal steering committee commented, âThe fall armyworm research collaboration portal will serve as an effective platform for communicating on research actions of the Fall Armyworm R4D International Consortium, led by CIMMYT and IITA. We encourage all the members of the Fall Armyworm R4D International Consortium to actively contribute to the portal.â
Fall armyworm (Spodoptera frugiperda) is an invasive insect pest that feeds on more than 80 plant species, causing major damage to maize, rice, sorghum, sugarcane but also other vegetable crops and cotton.
The pest is native to tropical and subtropical regions of the Americas. However, in 2016 it was reported for the first time in Africa, where it is causing significant damage to maize crops and has great potential for further spread and economic damage.
Fall armyworm has since spread to the Near East and Asia and, according to the Food and Agriculture Organization of the United Nations (FAO), it will likely soon be present in southern Europe. The FAO says that once fall armyworm is a resident pest in a country, it is there to stay and farmers need significant support to manage it sustainably in their cropping systems through integrated pest management activities.
The Fall Armyworm Research Collaboration Portal, funded by the UK Department for International Development (DFID) and the Directorate-General for International Cooperation (DGIS) of the Netherlands under the Action on Invasives program, will also encourage researchers to post preprints of research articles to the new agriRxiv, which offers researchers and students access to preprints across agriculture and allied sciences.
The portal will help reduce the duplication of research into fall armyworm prevention and management, provide a route for the rapid sharing of results and highlight opportunities for collaboration â encouraging rapid, iterative experimentation and global teamwork to address the spread and impact of fall armyworm.
A unique consortium of global and Pakistan scientists has helped to drive the countryâs recent growth in annual maize output to 6.3 million tons â nearly double the 2010 output â and energized the domestic production of affordable, quality seed of more nutritious and climate-resilient maize varieties.
With funding from the U.S. Agency for International Development (USAID), support from the Pakistan Agricultural Research Council (PARC) and other national experts, and coordination by the International Maize and Wheat Improvement Center (CIMMYT), the seven-year Agricultural Innovation Program (AIP) for Pakistan has contributed to the dramatic growth in national maize productivity that began in the early 2000âs, when more farmers adopted hybrid seed and better management practices.
âA key AIP focus has been to reach smallholder and marginal farmers with affordable maize seed from domestic suppliers, thus reducing maize seed imports that cost Pakistan nearly $80 million in 2018-19,â said AbduRahman Beshir, CIMMYT maize seed system specialist for South Asia. âAs part of this, the program has provided dozens of private companies with market-ready maize products and parental seed, as well as training in product marketing and business management and supporting the production and distribution of 175 tons of maize seed for on-farm demonstrations and promotion.â
âThe testing of diversified maize products and release of new varieties represent encouraging progress,â said AbduRahman Beshir (foreground), CIMMYT maize seed system specialist, speaking during a traveling seminar, âbut only advances in quality seed production and a competitive seed business at scale, with a strong case for investment by the private sector, will allow farmers to benefit.â (Photo: Waheed Anwar/CIMMYT)
Products from AIP have included more nutritious, diversified maize lines and varieties with tolerance to drought, infertile soils and insect pests, reducing the risk of smallholder farm families for whom losing a crop is catastrophic, according to Syed Khadem Jan, a farmer from Bajaur District of the tribal areas of Pakistan.
âOur area is very fragmented and maize yields have averaged less than 2 tons per hectare, due to the lack of improved varieties and management practices,â Jan said. âThe new maize seed with drought-tolerance is what farmers are looking for and will help to secure our food and livelihoods.â
Pakistan farmers sow maize on 1.3 million hectares in diverse ecologies ranging from 30 meters above sea level on the arid plains of Sindh Province to nearly 3,000 meters in the Karakoram mountain range of Gilgit Baltistan Province and as part of complex, irrigated cropping rotations in Punjab Province and small-scale, rain-watered farms in Khyber Pakhtunkhwa Province. Yellow maize is used widely in poultry feed and white maize for various foods including unleavened roti. Despite rising domestic demand for maize, production in Pakistan faces challenges that include a lack of maize varieties for various uses and ecologies, a weak seed delivery system, high seed prices, and unpredictable weather.
Since 2014, AIP has supported the testing by public and private partners in Pakistan of more than 3,000 maize products from breeding programs of CIMMYT and partners such as the International Institute of Tropical Agriculture (IITA). The extensive testing resulted in the identification of 60 new maize hybrids and varieties which CIMMYT handed over, together with their parental lines and breeder seed, to 16 public and private partners, according to Beshir.
âThe maize seed distributed through AIP is enough to sow some 9,000 hectares, potentially benefitting nearly 110,000 families,â he said. âSimilarly, CIMMYT has shared over 150 elite maize lines that have various preferred traits to foster variety registration, on-farm demonstrations, high-volume seed production, and intensive marketing. These contributions have broadened the genetic diversity and resilience of Pakistanâs maize and, through fast-track testing, saved partners at least eight years and considerable money, over having to develop them on their own from scratch and to pass them through conventional adaptation trials.â

Biofortified varieties provide better nutrition
Through AIP and national partners such as the University of Agriculture Faisalabad, farmers are testing pro-vitamin-A-enriched maize hybrids that are also remarkably high-yielding, helping to address one of the countryâs chronic nutritional deficiencies. With the same aim, in 2017 the national variety evaluation committee approved the release of two âquality protein maizeâ hybrids, whose grain has enhanced levels of the amino-acid building blocks for protein in humans and other monogastric animals.
Thanking USAID and the government of Pakistan, as well as 22 public and private partners across the maize value chain, Muhammed Imtiaz, CIMMYT country representative for Pakistan and AIP project leader, underscored the importance of specialty maize products for vulnerable communities.
âStrengthening âAgriculture-to-Nutrition Pathwaysâ is a centerpiece of AIP and part of CIMMYT efforts to provide nutritious food for the needy,â Imtiaz said. âThe introduction and evaluation of quality protein, Provitamin A and zinc enriched maize products represent a significant contribution both for the maize seed sector and Pakistanâs agricultural transformation.â
Addressing a 2020 AIP meeting, Muhammad Azeem Khan, PARC Chairman, urged stakeholders to use the new maize varieties. âI want to reiterate the importance of collaboration among public and private stakeholders to produce seed at scale, so that the diverse maize varieties can make it to the farmers’ fields as quickly as possible,â he said.
Maize seed producers acknowledge the value of AIP training and support in new business models. âWe are grateful to CIMMYT for reviving and helping the crawling maize seed industry to walk,â said Aslam Yousuf, Managing Director of HiSell Seeds Private Ltd. Company. âNow we need to learn to run.â
Dating back to the 1960s, the research partnership between Pakistan and CIMMYT has played a vital role in improving food security for Pakistanis and for the global spread of improved crop varieties and farming practices. Norman Borlaug, Nobel Peace laureate and first director of CIMMYT wheat research, kept a close relationship with the nationâs researchers and policymakers.

The outbreak of maize lethal necrosis (MLN) disease in east Africa in 2011 (first reported in Kenyaâs South Rift Valley) was a major concern, given that maize is the regionâs most important staple crop. This disease is caused by co-infection of plants with two viruses â maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) â and can cause yield losses of up to 90%. It spread rapidly across east Africa, compromising food and economic security for several million smallholder farmers.
MLN is a complex challenge that must be addressed through a multipronged approach. While significant advances have been made through intensive efforts by CIMMYT and other partners in terms of identifying and developing MLN tolerant or resistant hybrids, the rapid spread of the epidemic over the last few years remains a concern for farming communities, policy makers, national plant protection organization and the commercial seed sector, as well as the international scientific community.
There is also increasing suspicion that commercial seed flows may have been the initial source of the dissemination of the MLN-causing viruses over large distances, and it is thought that transmission of MCMV through contaminated maize seed continues to be a major risk factor in the spread of MLN across east Africa and beyond. However, there is a lack of reliable information on various aspects of MLN epidemiology, including the rate of MCMV transmission through seed.
The project on âPreventing Seed Transmission of Maize Lethal Necrosis in Africaâ aims to generate a better understanding of these epidemiological issues to allow for more effective control of MCMV transmission through commercial seed, support the development of effective, evidence-based phytosanitary regulations, reduce MLN disease pressure in eastern Africa, and curb the spread to non-endemic countries in other parts of the continent.
Objectives
Develop appropriate protocols for assessing MLN transmission through seed
Develop reliable and cost-effective diagnostic protocols for curbing the spread of MCMV/MLN through seed implemented by NPPOs and commercial seed companies.
Determine the rates of transmission for the East African and US (Hawaiian) isolates of MCMV in tropical, subtropical and temperate maize germplasm
Understand the mode of MCMV transmission through commercial seed within endemic areas to allow more effective control
Determine the distribution of MCMV in maize seed, and the effects of seed treatments on virus transmission
Identify economical treatment methods to reduce or prevent MCMV transmission through seed for commercial seed industry and casual seed trade
Generate detailed understanding of the role of root debris on persistence of MCMV in the soil, the persistence of the virus in different soil types, and the duration of virus viability in the soil
Disseminate science-based knowledge and evidence generated through this project to National Plant Protection Organizations (NPPOs) and Ministries of Agriculture in sub-Saharan Africa
The fall armyworm (Spodoptera frugiperda; FAW), an insect-pest native to the Americas, has been a persistent and serious pest of maize for over a century. Public and private sector scientists in the Americas â particularly in Brazil and the United States â have developed and deployed effective strategies to control the pest.
Incidence of fall armyworm was first reported in Nigeria in January 2016, and subsequently in over 40 countries across Africa. In Asia, the pest was first reported in India in mid-2018, and has since emerged in several countries in the Asia-Pacific. Strategies for fall armyworm management in both Africa and the Asia-Pacific can benefit immensely from those already fine-tuned in the Americas, with necessary customization to fit local agroecologies and farming systems. There is also a need to intensively work on various aspects of integrated pest management (IPM) for effective and sustainable fall armyworm management. This includes Research-for-Development (R4D) for discovering, validating and piloting best-bet technological interventions or management practices.
This project brings together the expertise of key institutions with long-standing experience in effectively dealing with transboundary insect-pests to strengthen the capacities of Africa- and Asia-based institutions in fall armyworm management. The goal is to develop and disseminate comprehensive, expert approved, IPM-based fall armyworm pest management practices that will enable various stakeholders â especially farmers, extension agents, and pest control advisors â to effectively scout, determine the need for, and appropriately apply specific interventions to control the fall armyworm in maize and other crops in Africa and Asia.
Objectives
Develop, publish and disseminate comprehensive, expert-approved, IPM-based information resources for various stakeholder groups
Integrate traits for fall armyworm resistance into the CIMMYT breeding pipeline
Establish a fall armyworm Research-for-Development (R4D) Consortium
