Global concerns are escalating as population growth, climate challenges and regional conflicts contribute to a food crisis. CIMMYT, in collaboration with 13 countries, is registering 160 drought-tolerant maize varieties to address changing climatic conditions, underscoring the need for unified efforts in global agricultural organizations.
On December 9, 2023, CIMMYT and the World Vegetable Center (WorldVeg) signed a memorandum of understanding (MoU) to further promote research and development, capacity strengthening activities and facilitate joint learning and the exchange of information and technology between the two organizations.
Sustainable diversification of food systems, good agricultural practices and safe and sustainable development of cereal and vegetable production systems and agrifood value chains sits at the core of this partnership.
The ultimate objective of the MoU is to further contribute to the achievement of the Sustainable Development Goals (SDGs), in particular SDG1 and SDG2, enhancing food and nutrition security, reducing rural and urban poverty and increasing employment opportunities in particular for women and youth.
CIMMYT and the World Vegetable Center are already partners in the Southern Africa Accelerated Innovation Delivery Initiative Rapid Delivery Hub (AID-I). Â Through this program, it is distributing seed kits directly to vulnerable populations such as pregnant and lactating mothers and children under five, as well as improving soil health, promoting the production of traditional African vegetables, and increasing employment opportunities through building vegetable businesses. Recent impacts in Zanzibar are a good example.

âThis collaboration between CIMMYT and WorldVeg is a testament to the potential of collective action, highlighting sustainable solutions and community empowerment as essential elements in combating malnutrition and enhancing overall well-being. We are building on the foundation already established by our collaborations within the Accelerated Innovation Delivery (AID-I) project in southern and eastern Africa,â said CIMMYT Director General, Bram Govaerts. âCIMMYT is excited to expand our connection with WorldVeg to bring innovations to even more people as crop diversification encourages improved nutrition.â
âThe World Vegetable Center is proud to deepen our work with CIMMYT. Reaching the Sustainable Development Goals will require not only advanced technologies but also systems to deliver those innovations to the people that need them most and this partnership will enable both priorities,â said Director General of the World Vegetable Center, Marco Wopereis. âPromoting and enhancing the availability of nutritious vegetables and cereals are vital to achieving these aims.â
By providing farmers with more options, CIMMYT and WorldVeg will promote the cultivation of diverse crops that are essential for a balanced and nutritious diet particularly among vulnerable communities around the world. By raising awareness about the significant benefits of incorporating different vegetables and cereals into daily diets, the partnership will inspire and encourage millions of people to fully embrace diversification and improved nutrition.

About the World Vegetable Center
The World Vegetable Center (WorldVeg) is an international non-profit institute for vegetable research and development. It mobilizes resources from the public and private sectors to realize the potential of vegetables for healthier lives and more resilient livelihoods.
WorldVegâs globally important genebank, improved varieties, production and postharvest methods help farmers to increase their vegetable harvests, raise incomes in poor rural and urban households, create jobs, and provide healthier, more nutritious diets for families and communities. With headquarters in Taiwan, field operations are led from regional centers in Benin, India, Mali, Tanzania and Thailand, and through offices in other key countries.
Latest advances in sensor technology and data processing allow early detection, mapping and monitoring of crop infestation, helping prevent large-scale outbreaks.
A recent study published in Nature Scientific Reports, assesses the capability of very high-resolution satellite (VHRS) imagery and high-resolution unmanned aerial vehicles (UAVs) imagery for high-throughput phenotyping and detecting impacts of wheat rusts in earlier crop growth stages. UAVs and VHRS offer high potential for nonintrusive, extensive, rapid and flexible measurements of plant biophysical properties at very high spatial and temporal scales.
The studyâled by CIMMYT in partnership with the Ethiopian Institute of Agricultural Research (EIAR) and Lincoln Agritech Ltd from New Zealandâestablishes that these advanced sensor technologies are emerging as gamechangers in crop health management. They save time, complement traditional disease scoring methods and field surveys, and are cost-effective.
Further, the study establishes that multispectral VHRS sensors can pave the way for the upscaling of disease severity assessment from plot to regional scales at early growth stages.
Wheat rust is a global challenge
Globally, crop infections are an increasing threat to crop production and food security. Increased cross-border trade and travel, coupled with a changing climate are resulting in increased frequency and severity of crop disease outbreaks. Of all the diseases that affect wheat, wheat rusts are among the most damaging, capable of causing epidemics on a vast scale with significant economic and production losses. As of date, global losses from wheat rusts equate to 15 million tonnes per year (USD $2.9 billion). In Ethiopia, a major stripe/yellow-rust epidemic in 2010 affected an estimated 600,000 hectares, resulting in production losses of 15â20% and causing economic losses of USD $250 million. Similarly, a stem/black rust (SR) epidemic from 2013-2014 infected approximately 40,000 hectares. SR, which can cause 100% crop loss within weeks, is re-emerging as a major concern to wheat production.
Early detection, monitoring and timely intervention is key
Rapid early-season detection, monitoring and timely control of wheat rusts in susceptible varieties are critical to avoid large-scale outbreaks, especially in countries where fungicides are scarcely available or too costly for smallholders. UAV-based high-throughput phenotyping (HTP) has been recently investigated to support wheat improvement breeding, in particular, to assess plant growth development, canopy architecture, physiology, reaction to abiotic stress, crop disease and insect pest response, and wheat yield.
Figure 1
Spectral and thermal measurements at the plant and canopy levels allow for monitoring the interactions between plant germplasm and environmental (abiotic and biotic) factors. The current study identifies several spectral features from UAV and VHRS multispectral imagery that have strong assessment power for the detection of combined wheat rust diseases at early crop growth stages.
During a randomized trial conducted in Ethiopia, six bread wheat varieties with differing rust resistance were monitored using UAV and VHRS. In total, 18 spectral features were tested to assess stem and yellow rust disease progression and associated yield loss. Spectral properties of the wheat canopy (e.g., pigmentation, moisture, and biomass) are altered under rust disease stress. Using multispectral images and derived vegetation indices, it is possible to determine crop susceptibility to diseases and consequently can be used for detection and monitoring of wheat rusts.
Figure 2
Recent research on wheat, maize and dry bean demonstrated strong and significant correlations between vegetation indices extracted from UAV and VHRS imagery, confirming the feasibility of VHRS-HTP targeting biomass and yield; however, such satellite applications for plant breeding programs are still scarce.
Looking ahead to upscaling
This study provides valuable insight into the upscaling capability of multispectral sensors for disease detection from UAV imagery at 5Â cm per pixel to pan-sharpened satellite imagery at 50Â cm per pixel, demonstrating a first step towards upscaling disease detection from plot to regional scales. Further work will expand and improve current methodology to examine the VHRS detection capability towards machine and deep learning techniques (e.g., convolutional neural network) to allow for continuous monitoring systems, focusing on both single and mixed rust diseases under different treatments (e.g., variable fungicide rates, irrigation rates).
The early detection of diseases through spectral analysis and the integration of machine learning algorithms offers invaluable tools to mitigate the spread of infections and implement prompt disease management strategies.

On October 4, 2023, CIMMYT continued its online seminar series â Catalysts of Change: Women Leaders in Science. The event featured a talk by Esther Ngumbi, an entomologist and academic at the University of Illinois Urbana-Champaign.
A riverside farm
Born into a small, rural community on the Kenyan coast, Esther Ngumbi grew up farming alongside her family. âI enjoyed the process of growing crops because I knew at the end of the season, we would have extra food for ourselves,â she explained. By the age of seven she decided she wanted to go it alone, and her father provided a small strip of land by the river, where she took to growing vegetables.
âEvery morning I would sit there and just enjoy looking at this thriving cabbage patch I had,â she says. âAnd then one day the rains came. It rained for three days, the field flooded, and by the time the water receded I had lost my cabbages. The joy that had built was gone.â
âBut this heartbreak continued,â she added. âHalfway through the season I would watch all our hard work go to waste.â Along came insects, drought, or floodingâall the stresses associated with climate changeâand for her family it would mean no food. Ngumbi soon realized that this was not limited to her familyâs farm: her neighbors, community, county, and country were all impacted by these challenges, leading to widespread food insecurity.
Feeding curiosity
âAs a girl I was very curious,â said Ngumbi. âHow do these insect pests find our crops? And when they find them, why arenât our crops resilient enough to overcome these stresses? Little did I know that this curiosity would lead me into what my career is today: an entomologist.â
âBut growing up in a rural village there were no role models; there were no scientists. There were no people I could look up to and be inspired to know that you could make a career out of entomology or that you could be a woman in science.â
Despite initially considering a career in accountancy, Ngumbi ended up studying for a BSc in biochemistry and zoology at Kenyatta University, where she immediately fell in love with practical research. âStepping into the lab was such an exciting day for me,â she recalled. âI had so many questions, and I remember not wanting to leave because I wanted to answer all the questions I had grown up with.â
Later, extra-curricular experience at a local research center would feed her interest in entomology. The scientists she ended up working with ran a biological control program to assess how maize is impacted by lepidoptera pests, and the natural biological control agents that could be used to combat these. âHow do plants communicate and call for help? Through releasing a chemical. I discovered that there is a wave of communication happening between our food crops and the community of organisms that associate with plants.â
Eager to learn more, Ngumbi went on to pursue an MSc before joining a Ph.D. program at Auburn University in Alabama, USA. âMy parents had always told me that education is the gateway out of poverty, and they consistently encouraged me to go to the highest level. I knew I had to go to the top.â
At Auburn she had the opportunity to delve deeper into how plants defend themselves, and her successful research into beneficial soil microbes led to at least three U.S. patents. Following a few post-doctoral positions, she landed a role at the University of Illinois Urbana-Champaign, where she currently works as an assistant professor in the Departments of Entomology and African American Studies.
Bringing others along
Ngumbi credits mentorship with getting her to where she is today. âAt Kenyatta University my teachers saw a spark in me; I was curious and wanted to find answers. Mentors introduced me to scientists the International Centre of Insect Physiology and Ecology (ICIPE), so I could carry out experiments beyond what we were doing as part of my course.â
She recalled walking across the stage during her Ph.D. graduation ceremony, a key moment of reflection. âIt was real that there were very few women like me in science. That I was only one of the many women I had grown up with that was privileged to have a PhD. And I wanted not to be the only person,â she said. âI wanted to make sure that I would leave open the same door I had walked through. That I would do my best to bring other women along.â
âI would step up to be a mentor. Step up to encourage other women. Step up to encourage other children from rural communities to say: you can do it, you can dream, you can follow your passions, you can be a scientist.â
With this in mind, Ngumbi ensures she collaborates with others in all areas of her research, incorporating young researchers into her labs and working directly with farmers. âIâm committed to ensuring that farmers who work so hard â especially smallholders â can grow crops and see all their hard work pay off.â
âI will continue to follow this journey of finding solutions to feed our growing planet, but I know that I cannot do it alone. We need all of us,â she added. âWe still have very few women scientists â UNESCO estimates around 30% â and I hope that by the time Iâm done with my career that number changes. But itâs going to depend on all of us.â
Ngumbiâs talk was followed by a Question and Answer led by Olivia Odiyo, a CIMMYT research associate based in Nairobi. The full discussion can be viewed online here. Spanish and French-language audio is also available.
Wheat DEWAS, funded by the Bill & Melinda Gates Foundation and the UKâs Foreign, Commonwealth & Development Office, is expanding to strengthen wheat resilience in East Africa and South Asia. The collaborative effort is led by CIMMYT and Cornell University, which includes 23 organizations across continents.
Nigerian wheat scientists and millers recently recognized and thanked CIMMYT for its contributions to four new wheat varieties released to farmers, citing the varietiesâ exceptional performance in field trials and farmers’ fields across national wheat-growing regions.
âThe release of these four wheat varieties, uniquely tailored to suit our local conditions, has marked a significant milestone in enhancing food security and farmer livelihoods,â said Ahamed T. Abdullahi, agronomist for wheat value chains at the Flour Milling Association of Nigeria (FMAN), in a recent message to CIMMYTâs Global Wheat program. âThe improved characteristics, such as higher yield potential, enhanced disease resistance, and adaptability to local climatic conditions, have significantly boosted wheat productivity. Moreover, the quality profiles of these varieties, as expressed in Nigeria, comply fully with the standards required by the local industry.â
Two of the varieties are bread wheat and yield up to 7 tons of grain per hectare, according to a recent Nigeria Tribunearticle. The other two are durum wheat, a species grown to make pasta and foods such as couscous and tabbouleh. One of those, given the name LACRIWHIT 14D in Nigeria, was from a CIMMYT wheat line selected for its novel genetic resistance to leaf rust and high-yield potential under irrigated conditions. It was also released in Mexico under the name CIRNO C2008 and is the countryâs number-one durum wheat variety, according to Karim Ammar, a wheat breeder at CIMMYT.

âAside from its high yield potential, it has considerable grain size and an aggressive grain fill that is expressed even under extreme heat,â explained Ammar. âThese characteristics have certainly helped its identification as outstanding for Nigerian conditions.â
Writing on behalf of FMAN and the Lake Chad Research Institute (LCRI) of Nigeriaâs Federal Ministry of Agriculture and Rural Development, Abdullahi said, âWe deeply appreciate the expertise and support provided by CIMMYT throughout the development and release process. Your team’s technical guidance on the access to germplasm has played a crucial role in equipping our farmers and extension agents with the necessary skills and resources for successful wheat cultivation.â
Nigeria has a fast-growing population which, coupled with increasing per capita demand for wheat, has made increasing wheat production a national priority, according to Kevin Pixley, director of the Dryland Crops and Global Wheat programs at CIMMYT.
âUntil recently, Nigeria produced only 2% of the wheat it consumes, but potential exists to double the current average yield and expand wheat production by perhaps 10-times its current area,â said Pixley. âNew wheat varieties will be essential and must be grown using sustainable production practices that improve farmersâ livelihoods while safeguarding long-term food security and natural resources.â
Abdullahi said the release of the varieties demonstrated the power of collaborative research and highlighted the potential for future collaborations. âWe look forward to continued collaborations and success in the pursuit of sustainable food systems.â
CIMMYT and partners in Kenya recently marked the 10th anniversary of two major facilities that have been crucial for maize breeding in sub-Saharan Africa. The Maize Doubled-Haploid (DH) facility and the Maize Lethal Necrosis (MLN) screening facility at the Kenya Agriculture and Livestock Research Organization (KALRO) centers in Naivasha and Kiboko, respectively, have made immense contributions to the rapid development of higher-yielding, climate-resilient and disease-resistant maize varieties for smallholder farmers across the continent.

âThese two facilities have been instrumental in furthering KALROâs mission to utilize technology in the service of Kenyaâs smallholder farmers,â said KALRO Director General/CEO, Eliud Kireger. âThey also exhibit the spirit of cooperation and collaboration that is necessary for us to meet all the challenges to our food systems.â
âDeploying a higher yielding maize variety may not be impactful in eastern Africa if that variety does not have resistance to a devastating disease like MLN,â said CIMMYTâs Director General Bram Govaerts. âThese two facilities demonstrate the holistic methods which are key to working towards a more productive, inclusive and resilient agrifood system.â
Maize DH facility
Hybrid maize varieties have much higher yields than open-pollinated varieties and are key to unlocking the agricultural potential of maize producing countries. The doubled haploid process is an innovative technology producing within a year genetically true-to-type maize lines that serve as building blocks for improved maize hybrids.
Unlike conventional breeding, which takes at least 7 to 8 generations or crop seasons to develop parental lines, DH lines are generated within two seasons, saving significant time, labor and other resources. DH maize lines are highly uniform, genetically stable, and are more amenable to the application of modern molecular tools, making them perfect resources for breeding elite maize hybrids.

The aim of CIMMYTâs maize DH facility is to empower the breeding programs throughout the low-and middle-income countries in Africa by offering a competitive, accessible, not-for-profit DH production service that will accelerate their rate of genetic gain and fast-track development of improved maize varieties for farming communities.
Since 2017, the DH facility has delivered 280,000 DH lines from 1,840 populations of which 20% were delivered to public and private sector partners. CIMMYT maize breeding programs and partner organizations have embraced the use of DH technology, with many of the newest maize hybrids released in Africa being derived from DH lines. The facility has also served as a training ground so far for over 60 scientists and hundreds of undergraduate students in modern breeding technologies.
âBefore 2013, DH technology was mainly employed by private, multinational corporations in North America, Europe, Asia and Latin America,â said CIMMYTâs DH Facility Manager, Vijay Chaikam. âBut the DH facility operated by CIMMYT at the KALRO Kiboko research station is specifically targeted at strengthening the maize breeding programs by the public sector institutions as well as small-and medium-size enterprise seed companies in Africa.â
The maize DH facility at Kiboko, Kenya, was established with funding support from the Bill & Melinda Gates Foundation and inaugurated in September 2013. The facility includes an administrative building, seed quality laboratory, training resources, artificial seed dyer, a cold-storage seed room, a chromosome doubling laboratory, greenhouse and a state-of-the-art irrigation system to support year-round DH production in the 17-hectare nursery.
MLN screening facility
MLN is a devastating viral disease that can decimate farmersâ fields, causing premature plant death and unfilled, poorly formed maize ears, and can lead to up to 100 percent yield loss in farmersâ fields. Though known in other parts of the world for decades, the disease was first identified in eastern Africa in 2011. By 2015, MLN had rapidly spread across eastern Africa, including Kenya, Uganda, Tanzania, South Sudan, Rwanda, Democratic Republic of Congo and Ethiopia. CIMMYT scientists quickly discovered that almost all the commercial maize cultivars in eastern Africa were highly susceptible to the disease.
Against this backdrop, CIMMYT and KALRO recognized the urgent need for establishing a screening facility to provide MLN phenotyping service and effectively manage the risk of MLN on maize production through screening of germplasm and identifying MLN-resistant sources. The facility was built with funding support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture, and inaugurated in September 2013.

âThe MLN screening facility is a key regional resource in breeding for resistance to a devastating viral disease. The facility is indeed one of the key factors behind successful management of MLN and helping stem the tide of losses in eastern Africa,â said Director of the Global Maize Program at CIMMYT and One CGIAR Plant Health Initiative, B.M. Prasanna. âFighting diseases like MLN, which do not respect political boundaries, requires strong regional and local collaboration. The successes achieved through the MLN Screening facility in the past 10 years embody that spirit of collaboration.â Indeed, farmers in the region now have access to over twenty genetically diverse, MLN-tolerant/resistant maize hybrids released in eastern and southern Africa.
The facility is the largest dedicated MLN screening facility in Africa and has evaluated over 230,000 accessions (over 330,000 rows of maize) from CIMMYT and partners, including over 15 national research programs, national and multinational seed companies. The facility covers 20 hectares, of which 17 hectares are used for field screening of germplasm. Dedicated laboratories and screen houses cover the remaining 3 hectares.
âMLN phenotyping service is conducted under stringent quarantine standards and the high-quality data is shared with all the CGIAR and public and private partners. The MLN screening service has helped breeding programs across the continent, aided in undertaking epidemiological research activities, and supported capacity building of students from diverse institutions, and regional stakeholders regarding MLN diagnosis and best management practices,â said CIMMYTâs Maize Pathologist in Africa, L.M. Suresh.
âThe output of MLN resistant lines and hybrids has been remarkable,â said Director of Phytosanitary and Biosecurity at the Kenya Plant Health Inspectorate Service (KEPHIS), Isaac Macharia. âAnd the facility has strictly adhered to quarantine regulations.â
In Uganda, the MLN facility was crucial in the ârelease of the first-generation MLN tolerant hybrids and dissemination of MLN knowledge products that minimized the economic impact of MLN,â said the Director of Research of the National Crops Resources Research Institute, Godfrey Asea.
Peter Mbogo, maize breeder with Seed Co Group, said, âThis is the only quarantine facility in the world where you can screen against MLN under artificial inoculation. It has been an excellent return on investment.â
Many people on the islands of Zanzibar face food insecurity and nutritional challenges. The Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub, implemented by CIMMYT, has partnered with the World Vegetable Center (WorldVeg) to directly distribute health diet seed kits to vulnerable households, while prioritizing vulnerable groups such as pregnant and lactating mothers and children under five.
The kits contain a diverse selection of nutrient-rich vegetables specifically chosen for their high nutritional value, ensuring optimal health and development.

To date, the partnership has reached an impressive number of households in Zanzibar. Over 1,350 health diet seed kits have been distributed, or one seed kit per household, benefiting approximately 4,050 individuals (considering at least three people per household). These numbers showcase the tangible impact AID-I has made in addressing the root causes of malnutrition and hidden hunger, providing a sustainable pathway towards improved health and a brighter future for Zanzibar.
The World Vegetable Center (WorldVeg) conducts research, builds networks, and carries out training and promotion activities to raise awareness of the role of vegetables for improved health and global poverty alleviation.
âThis initiative holds tremendous promise in fostering long-term improvements in food security, nutrition, and overall well-being for the communities in Zanzibar and shows the power of collaboration,â said Kevin Kabunda, CIMMYT lead for the AID-I project.
Seed variety encourages improved nutrition
A key strength of the seed kits lies in their diversity. Each kit comprises a range of seeds for various crops, including legumes and nutrient-rich vegetables. This includes amaranth consumed as leafy and grain, African eggplant, Ethiopian mustard, African nightshade, and cowpea. The combination of these diverse crops ensures a more resilient and nutritious food supply, essential to combating malnutrition and fostering agricultural sustainability in the islands.
The seed kits are tailored to suit the local agroecological conditions, considering the specific needs and preferences of farmers in Zanzibar. This localization approach enhances the adoption of the kits and maximizes their potential impact on food security and dietary diversity.
âThe partnership between WorldVeg and CIMMYT has been invaluable in driving the success of this activity in Zanzibar,â said Jeremiah Sigalla, WorldVeg technical lead for the AID-I project in Zanzibar. âBy providing farmers with these healthy diet seed kits, we aim to promote the cultivation of diverse crops that are essential for a balanced and nutritious diet and its attendant benefits, particularly among vulnerable communities.â
By raising awareness about the significant benefits of incorporating diverse vegetables into daily diets, the partnership has inspired and encouraged the community to fully embrace the intervention. This collaboration between CIMMYT and WorldVeg is a testament to the potential of collective action, highlighting sustainable solutions and community empowerment as essential elements in combating malnutrition and enhancing overall well-being in Zanzibar.

The Honorable Shamata Shame Khamis, the minister of Agriculture, Irrigation, Natural Resources and Livestock in Zanzibar joined a health diet seed kit distribution event at Michiweni district in Pemba, on June 30, 2023, where he commented that the consumption of nutritious vegetables in Zanzibar is very low, and malnutrition-related cases are increasing because of poor daily diets. He also extended his appreciation to the AID-I project, recognizing that this initiative is not only important but also timely, as it serves to meet the urgent need for promoting and enhancing the availability of nutritious vegetables in Zanzibar.
CIMMYT’s partnership with the Government of India, which spans more than five decades, is one of the longest and most productive in the world.
In October, a group of about 18 scientists from Bihar Agricultural University (BAU), Indian Council for Agricultural Research (ICAR), and Dr. Rajendra Prasad Central Agricultural University (RPCAU) visited CIMMYT headquarters in Mexico to participate in the course on “Innovation in Agri-food Systems through the Hub Model”.
In a strategic move to improve food security and promote agricultural development, Syngenta Foundation Nigeria, one of the key partners in the Dryland Crops Program (DCP), has introduced a new initiative known as the AVISA Farmers’ Hub. The initiative was launched at an event in the Murya Community of Obi Local Government Area in the Nasarawa State of North Central Nigeria. The Farmers’ Hub aims to support and empower farmers in the region, contributing to the overall objectives of the DCP.
The introduction of the Farmersâ Hub comes at a time when smallholder farmers in the region are grappling with limited access to essential resources such as knowledge, high-quality inputs, modern technology, and reliable markets, all of which are critical for achieving high-quality agricultural productivity.
A farmers’ hub (FH) is an all-inclusive commercial platform that provides diverse inputs such as seeds, seedlings, fertilizers, and crop protection products, as well as price and weather information. In addition, it provides farmers with value-added services such as aggregation, cleaning, sorting and grading of produce, bulk sales, training, equipment leasing and rental, financing, and trade credit. Smallholder farmers can now take advantage of the opportunities provided by the Farmers’ Hub by transitioning from subsistence agriculture to a commercially oriented system.

During the event, the Country Program Manager of Syngenta Foundation Nigeria, Isaiah Gabriel, emphasized the foundation’s dedication to commercializing AVISA crops: “The foundation is working to facilitate the commercialization of cowpea, sorghum, groundnuts, and pear millet.â Gabriel also emphasized the importance of raising awareness among farmers and establishing a platform that provides smallholder farmers with improved seeds, seedlings, fertilizers, mechanization, and other value-added services. He urged farmers in the state to maximize their utilization of the Farmers’ Hub and its services, which are intended to facilitate improved seed production and service delivery.
The Farmers’ Hub was established with the goal of resolving access issues, optimizing yields, aggregating grains, and overcoming market challenges. Finally, the hub hopes to improve food security and increase the income of smallholder farmers.
Prof. Mary Yeye, the National Coordinator of AVISA, commended the initiative and emphasized the importance to farmers of taking advantage of the project and making prudent use of its resources as she addressed the participants.
Experts in attendance, that included Prof. Lucky Omoigui, a seed system specialist from the International Institute of Tropical Agriculture (IITA), Prof. SG Gaya, a groundnut breeder from Bayero University Kano (BUK), and Prof, Alhassan Lalihu from the Federal University Lafia, discussed several of the obstacles to high agricultural productivity. These factors include restricted access to improved seeds, expensive fertilizers, and security concerns. The experts lauded the Farmers’ Hub as the final step in delivering resources to smallholder farmers. In addition, they urged all levels of government to intensify efforts to subsidize input costs and improve farmers’ security.
The program manager of the Nasarawa State Agricultural Development Program, Emmanuel Alanama, responded by thanking Syngenta Foundation for selecting Nasarawa State for this significant project. He acknowledged that 75 to 80 percent of the state’s population are farmers and expressed the willingness of the state government to collaborate and support any agricultural initiatives.

Rowland Alaku, manager of the Farmers’ Hub, assured farmers that they would have guaranteed access to quality seeds. The farmers in attendance expressed their gratitude for the initiative and promised to utilize the hub fully in order to benefit their own farming endeavors.
Other dignitaries in attendance included Prof. Johnson Onyibe from Ahmadu Bello University (ABU), Zaria; Dr. Teryima Iorlamen from the University of Agriculture, Makurdi; and several village heads. More than 150 farmers, stakeholders, and government officials attended the event, highlighting its importance.

Farmers, stakeholders, and partners, including seed companies, Hamara Chicks, PHI Commodities, the International Livestock Research Institute (ILRI), BioHUB Trust (BHT), Kurima Machinery and Technology, and Zimplow Limited, participated in the Seed and Livestock Fair in the Mbire and Murewa districts of Zimbabwe, which showcased indigenous and improved seed varieties and different technologies to strengthen crop and livestock value chain systems.
Initiated by CIMMYT in 2022, as the CGIAR Initiative on Agroecology, these series of fairs have become instrumental in bringing agrodealers closer to farmers and showcasing sustainable technologies and innovations that have the potential to strengthen production systems. It was also an opportunity for the agroecology initiative team to provide feedback to farmers and stakeholders on ongoing activities and technologies that were being tested since the initiative’s inception in Zimbabwe. By adopting a multi-partner approach, these fairs bring local food systems actors together to ensure food and nutrition security and improved income for farmers.
“The agroecology initiative has been collaborating with an array of organizations and institutes that can support our mission towards promoting agroecology and improving farming production, including other CGAIR entities like IWMI and ILRI, Hamara Group, Ecolyfe, and PHI Commodities,” said Dorcas Matangi, research associate at CIMMYT.
This year’s edition of the seed and livestock fair “Fostering Synergies: Diverse Crops, Livestock and Inclusive Communities” advocated for enhancing synergies within the farm to foster sustainable agroecology transitions for resilient food and nutrition outcomes. With over 800 farmers and stakeholders participating, the event provided a vibrant platform for knowledge sharing, exploration of indigenous and improved seed varieties, and sensitization of innovative technologies.
“The seed and livestock fairs hosted by the agroecology initiative bring together farmers and food system actors from all walks of life to foster learning around agroecology, which includes the importance of diversity (crop and livestock) while also appreciating local innovations in the respective area,” said Jesca Mapfinya, a Murewa farmer.
The right seed, assures a good harvest
Various seed companies participated in the fair to showcase different seeds which are well adapted in Murewa and Mbire districts. Each agroecological region in Zimbabwe is unique, with adaptable seed varieties that are either landrace or improved. Local landraces and many underutilized crop species are adapted to weather and climate variability, climate change, and extreme weather such as drought and heat stress. Farmers indicated that their motivations for growing landraces are related to sustainable farming systems suitable for social, cultural, nutritional, and agronomic traits. Their place in rural communities remains important, providing much-needed functional diversity and social capital. Including improved varieties within the basket of options can further intensify production systems in these communities.
“Primarily, we sell seed varieties and build farmer capacity around appropriate agronomic practices. The seed fairs are a good platform to match seeds and systems and allows a farmer to provide feedback about our seed varieties and how they are performing in the respective areas,” said Onesmous Satenga, SeedCo.

Building crop and livestock synergies
For the first time since the inception of the fairs, livestock such as cattle, sheep, goats, chicken and rabbits were displayed. Partners, including ILRI and the Hamara Chicks, who are into sasso chicken and feed production, reiterated the importance of crop diversity for improved livestock nutrition. ILRI and the Grasslands Research Institute exhibited various local feedstocks and alternative livestock feed grasses and also presented several feed formulations. Farmers also provided feedback on the feeding strategies employed for different livestock.
“We feed cattle with poultry litter, maize grain, maize stover, and groundnut shells in various proportions depending on the availability of these feed sources. Forage legumes such as velvet bean (mucuna pruriens) and lablab (lablab purpureus) have been introduced, and we have started to grow these for feed,” said Samson Tashaya, Murewa farmer.

Of keen interest to farmers and stakeholders was the sasso breed of chickens that the Hamara Group was promoting.
“We have recently joined as partners with CIMMYT and are promoting hybrid chicken production, especially sasso, here in Murewa ward 27 and 4. This is our first time coming to this seed fair, and it was a learning opportunity. The interactions with farmers were really good,” said Alan Norton, team leader at Hamara Chicks.
Modernizing smallholder production systems
Mechanization experts from Kurima Machinery and Zimplow shared their recommendations at the fair. They acknowledged that farmers rely heavily on scarcely available labor and production activities that are backbreaking. They advocated for modern production systems to produce more food and support economic transformation. Experts from Kurima Machinery and Zimplow demonstrated several machines that could aid farmers in various on-farm activities.
“This fair has come at the right time as I begin land preparation for my pfumvudza (conservation agriculture plots). I have seen how the basin digger works, and I am keen to purchase an instrument to make my work much easier,” said Chief Chisunga, Mbire.
âThis crop season’s outlook is still unclear, but weather experts have warned of an intense El Nino event likely to happen in the second half of the season. Technologies such as conservation agriculture can ensure good moisture retention in crop fields, and it needs to be paired with good agronomic practices,” said Tafadzwanashe Mabhaudhi, climate and food systems expert.

The event saw four Chinese institutions sign agreements with CIMMYT to promote mutual partnership: the Institute of Crop Sciences at CAAS, Huazhong Agricultural University, Henan Agricultural University, and Xinjiang Academy of Agricultural Sciences. Additionally, a ceremony was held in which 28 alumni and four partner institutions received awards for their contributions to scientific collaboration.
A fruitful partnership
China and CIMMYT have had a fruitful partnership over the past 45 years in areas including shuttle breeding, genomic research, sustainable crop systems and trainings that have greatly contributed to strengthening Chinaâs food security with positive spillover effects to neighboring countries in the region.
The successful CIMMYT-China collaboration in shuttle breeding from the 1980s laid the foundations for the establishment of CIMMYTâs office in China in 1997. Bilateral cooperation then expanded to set up a Joint Lab between CIMMYT and the Ministry of Agriculture and Rural Affairs (MOARA), in which more than 20 Chinese agricultural research institutes also participated. More recently in 2019, CIMMYT and the Jiangsu Academy of Agricultural Sciences jointly opened a new screening facility for the deadly and fast-spreading fungal wheat disease, fusarium head blight.

CIMMYT has transferred approximately 26,000 wheat seed samples to more than 25 institutions in China, which are now using these materials in their breeding or crop improvement programs. As a result of these efforts, 300 wheat cultivars derived from CIMMYT germplasm have been released and are currently grown on 10% of Chinaâs wheat production area. This collaboration between CIMMYT and China has yielded 10.7 million tons of wheat grain with an estimated value of $3.4 billion.
Additionally, CIMMYT-derived maize varieties have been planted on more than one million hectares across China, and 3,000 new inbred maize lines have been introduced through CIMMYT to broaden the genetic base of Chinese breeding efforts in southwestern provinces.
In a visit to 5 model sites for maize marketing in midwestern Nepal, 30 federal, provincial and local agricultural authorities were impressed with the coordination and capacity development among market actors, improved supply chain management and leveraging of government support, all of which are benefiting farmers and grain buyers.
Following visits to commercial maize fields and hearing stakeholdersâ perceptions of progress and key lessons, the authorities proposed additional funding for irrigation, machinery, grain grading and crop insurance, among other support, and promised to help expand activities of the model sites, which were established as part of the Nepal Seed and Fertilizer (NSAF) project.
Led by CIMMYT with funding from the United States Agency for International Development (USAID) and in its second-last year of operation, the project is working to raise crop productivity, incomes and household food and nutrition security across 20 districts of Nepal, including 5 that were severely affected by the catastrophic 2015 earthquake and aftershocks which killed nearly 9,000 and left hundreds of thousands homeless.

The visitors included officials and experts from the Ministry of Agriculture and Livestock Development (MoALD); the Department of Agriculture (DoA); the Ministry of Land Management, Agriculture and Cooperatives (MoLMAC); the Agriculture Development Directorates (ADD) for Lumbini and Sudurpaschim provinces; the Agriculture Knowledge Centres (AKC) of Banke, Kailali, Kanchanpur, Dang, and Kapilvastu districts; the Prime Minister Agriculture Modernization Project (PMAMP) offices of Dang and Bardiya; and the National Maize Research Program; the Department of Livestock Services; along with NSAF project team members.
The participants interacted with farmers, cooperative leaders, traders, rural municipality officials and elected representatives, and feed mill representatives. Sharing their experiences of behavioral change in maize production, farmers emphasized the benefits of their strengthened relationships with grain buyers and their dreams to expand spring maize cultivation.
Shanta Karki, deputy director the General of Department of the DoA lauded CIMMYT efforts for agriculture growth, improved soil fertility and sustainable agriculture development through NSAF.
Madan Singh Dhami, secretary, MoLMAC in Sudurpaschim Province, emphasized the importance of irrigation, building farmersâ capacities and interactions with buyers, and applying digital innovations to catalyze extension.
CIMMYT scientists have been based in CIMMYTâs office in Nepal and worked with Nepali colleagues for more than three decades to boost the productivity, profitability and ecological efficiency of maize- and wheat-based cropping systems and thus improve rural communitiesâ food security and livelihoods.
Smallholder mechanization out scaling depends upon the availability of skilled mechanics who are fully oriented with machinery operation. However, this crucial skillset is often identified as a missing link. In many instances, lack of care or regular checks and the absence of readily available mechanics has led to the failure of mechanization projects in sub-Saharan Africa, with frequent machine breakdowns and equipment left sitting idle long after a project intervention. Across smallholder farming communities, this phenomenon can be seen through the presence of obsolete and abandoned machinery often serving as breeding grounds for birds.
The Feed the Future Zimbabwe Mechanization and Extension Activity, funded by the United States Agency for International Development (USAID), aims to break this vicious cycle by improving the skillset of local mechanics and helping them stay in tune with evolving innovations in farm machinery. Implemented by CIMMYT, this activity targets existing mechanics across ten districts in Zimbabwe, offering specialized maintenance services to providers who own machinery. Through investing in their training, local capacity to troubleshoot, service and repair machinery will increase.

Gaining practical experience
 The program approaches training through full immersion and a deep dive into the individual components of key equipment. Workstations are set up to include a diesel engineâwhich forms the core of most of the machineryâa two-wheel tractor and post-harvest machines such as the multi-crop thresher, feed-chopper grinder and peanut butter machine.  For most of the participants, the workshop presents them with first-hand experience of handling such machinery.
 Andy Chagudhuma and Tendai Machonesaâfrom Bikita and Chiredzi, respectivelyâwere among the first ten mechanics to participate in the five-day training. âI learned about all the machines here,â says Chagudhuma, âbreaking them apart and fixing them. We worked through different scenarios while perfecting our knowledge on the operation of all the machinery.â With new skills gained, they eagerly await the opportunity to offer their expertise to service providers in their local areas, and a newfound confidence fuels their commitment to providing support through repair and maintenance work.
 However, one remaining challenge is the notable absence of female participants in the training. While the field of mechanics is often male-dominated, the Mechanization Activity seeks to promote a gender-inclusive environment for local mechanics and service providers through awareness meetings and skills training. In the future, more machinery and technical trainings will be targeted specifically towards women as a way to redress this imbalance.
Overall, the benefits of the training echo far beyond the workshop itself. Through the skills acquired, opportunities for additional income generation increase, and the participation of rural youths in mechanization-oriented businesses and a thriving local economy are possible. By empowering local mechanics, the Mechanization Activity not only breathes life into their communities and the machinery sector but also paves the way for one of the projectâs key objectivesâthe establishment of successful and entrepreneurial service providers.
The Seed Production Technology for Africa (SPTA) project, led by CIMMYT, has been selected by the CGIAR Gender Impact Platform as a successful case study of integrating gender into crop breeding.
The case study, published in Frontiers in Sociology, is one of fourteen that the CGIAR Genetic Innovation Gender strategy is drawing on to showcase lessons learned from practical experience. These case studies form a critical part of the efforts to pursue gender responsive or gender-intentional breeding and explore how these can inform larger breeding pipelines.
Maize is widely grown by both women and men in Africa. Evidence of gender-differentiated preferences for maize varieties remains inconclusive; however, there is evidence of gendered differences in management practices. Hybrids produced using SPTA segregate 1:1 for pollen producing and non-pollen producing plants referred to as 50% non-pollen producing (FNP) varieties. Previous research showed FNP offered a yield benefit under low input conditions. In the early stage of its inception, the project quickly recognized the potential implications of hybrids produced using SPTA for women and other resource-constrained smallholders in Africa.
Understanding gender-based differences
From the start, the SPTA team conducted a gender review that underscored the fact that women in the region often use less fertilizer than men, a challenge that is further compounded by cultivation of smaller plots and lower quality soils. This review led the breeding team to explicitly target women and resource-poor farmers with an ambition to increase yields on womenâs fields. From here henceforth, SPTA made it a priority to understand gender-based differences in performance and preference for new FNP maize varieties. This process involved ensuring both women and men farmers host trials to evaluate and attest to the performance of the FNP hybrids.
But these efforts were not without challenges. The team also found significant gender differences, particularly among women farmers in crop management practices and between farmersâ stated preferences during participatory varietal selection exercises and the varieties they used at home. This suggested that initial on-farm evaluations were not adequate for predicting real world demand for varieties. Moving forward, the evaluation strategy of SPTA evolved to enable variety evaluations under farmersâ preferred management practices.
The success of the SPTA team in ensuring that gender considerations were strongly embedded into the breeding program is attributed to strong collaboration across disciplines that included social scientists and gender researchers working closely with breeders, allocating funding to allow exploration, testing of gender topics and responsive variety evaluation tools and strong buy-in from leadership and donors. As the SPTA case highlights, there is value in starting small, building productive partnerships and collaborating to pilot and develop proof of concept for new models.
