As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the worldâs food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.
Achieving widespread food and nutritional security for the worldâs poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.
The importance of agroecological methods is starting to be a necessity across the Congo Basin. CIMMYT researcher, Prasanna Boddupalli, emphasises the importance of agroecological methods for biodiversity-smart agricultural development.

Small-scale farmers in Mexico often adopt conservation agriculture innovations gradually and piecemeal, to fit their diverse agroecological and socioeconomic contexts and risk appetites, according to studies and the on-farm experience of CIMMYT.
Research and extension efforts need to consider this in work with smallholders, said Santiago Lopez-Ridaura, a CIMMYT specialist in agricultural systems and climate change adaptation.
“Farmer practices typically involve heavy tillage before seeding, growing maize as a monocrop, and removing crop residues after harvest for use as forage,â explained Lopez-Ridaura. âFull-on conservation agriculture (CA) is a radical shift, requiring farmers to reduce or eliminate tillage, keep a permanent cover of crop residues on the soil, and diversify the crops they grow. It can support more intense yet environmentally friendly farming, reducing erosion, improving soil fertility and water filtration, boosting crop yields, and saving farmers money. However, it also requires purchasing or contracting specialized sowing implements and fencing fields or agreeing with neighbors to keep livestock from eating all the residues, to name just a few changes.â
Lopez-Ridaura and colleagues published a 2021 analysis involving farmers who grew maize and sorghum and keep a few livestock on small landholdings (less than 4 hectares), with limited mechanization and irrigation, in the state of Guanajuato, Central Mexico.
They found that scenarios involving hybrid maize plus a legume crop with zero-tillage or keeping a residue mulch on the soil provided an average net profit of some US $1,600 (MXP 29,000) per year, in addition to ecological benefits, added forage, and more stable output under climate stress.
âUsing a modeling framework from Australiaâs Commonwealth Scientific and Industrial Research Organization (CSIRO) that combines bioeconomic simulation, risk analysis, adoption theory, and impact assessment, we not only confirmed the worth of conservation agriculture but found that disaggregating CA into smaller component packages and including a more productive crop and variety were likely to increase farmersâ adoption, in riskier settings.â
Advancing more sustainable farming in Mexico
Conservation agriculture can generate substantial economic and environmental benefits under marginal conditions, particularly by enhancing climate change resilience, increasing soil organic matter, and retaining soil moisture. In Central Mexico dryland maize yields rose by 38-48%, after 10 years of implementing CA.
CIMMYT has studied and promoted zero-tillage for maize and other resource-conserving practices in Mexico for more than three decades, but efforts to spread sustainable farming and use of improved maize and wheat varieties redoubled thanks to MasAgro, a research initiative led by the Center and supported by the government of Mexico during 2010-21. Testimonials such abound of Mexican smallholder farmers who have adopted and benefited from CA practices through CIMMYT and national partners’ efforts in MasAgro and other initiatives.
Anurag Kumar is a senior research associate in CIMMYT under the Cereal System Initiative for South Asia (CSISA) project in India.
He is involved in Coordinating trials and demonstrations of the rice-wheat cropping system in Bihar. Other than coordinating trials and demonstrations, he is effectively strengthening partnerships with national and private partners. The extension of proven technologies is the core of the project so synergizing the effort of each partner for better spread.
Leveraging the leadership, science, and partnerships of the Mexico-based CIMMYT and the funding and research capacity of Mexicoâs Secretariat of Agriculture and Rural Development (SADER) during 2010-21, the program known as âMasAgroâ has helped up to 500,000 participating farmers to adopt improved maize and wheat varieties and resource-conserving practices on more than 1 million hectares of farmland in 30 states of Mexico.
As a result of MasAgro research hubs operating across Mexicoâs multiple and diverse agroecologies to promote the sustainable intensification of maize and wheat farming systems â including improved varieties and resource-conserving, climate-smart practices â yields of project participants for maize were 20% higher and for wheat 3% higher than local averages. Similarly, average net incomes for participating maize farmers were 23% greater and 4% greater for wheat farmers, compared to local averages.
The MasAgro biodiversity component gathered and analyzed one of the worldâs largest-ever samplings of maize and wheat genetic diversity, including CIMMYTâs own vast seed bank collections, to help identify and characterize new genes of interest for breeding. As one result, more than 2 billion genetic data points and over 870,000 data entries from associated field trials are freely available to the scientific community, via the projectâs online repository.
MasAgro has involved national and local research organizations, universities, companies, and non-government organizations working through more than 40 research platforms and 1,000 demonstration modules, while building the capacity of thousands of farmers and hundreds of technical and extension experts who serve them.
State-level partners sign on to MasAgro
Through MasAgro, CIMMYT entered into research and development partnerships with 12 Mexican states. An example is the mountainous, central Mexican state of Guanajuato, home to the El BajĂo region, one of Mexicoâs most productive farm areas but which also suffers from soil degradation, water scarcity, and climate change effects â challenges faced by farmers throughout Mexico. The governor of Guanajuato visited CIMMYT headquarters in Mexico in June 2023 to review progress and agree on follow-up activities.
CIMMYT has worked with Guanajuato state and local experts and farmers themselves to test and promote innovations through 7 research platforms reaching nearly 150,000 hectares. As of 2020, new crop varieties and resource-conserving, climate-smart management practices had helped underpin increases of 14% in irrigated wheat production and, under rainfed farming systems, improved outputs of 28% for beans, 150% for local maize varieties and 190% for hybrid maize, over state averages.
An integral soil fertility initiative has included the analysis and mapping of more than 100,000 hectares of farmland, helping Guanajuato farmers to cut costs, use fertilizer more effectively, and reduce the burning of crop residues and associated air pollution.
Service centers for the rental and repair of conservation agriculture machinery are helping to spread practices such as zero tillage and residue mulches. Supported by CIMMYT advisors, Guanajuato farmers are entering into equitable and ecologically friendly production agreements with companies such as Nestle, Kelloggâs, and Heineken, among other profitable and responsible public-private arrangements.
Acclaim and interest abroad for MasAgro
MasAgro has received numerous awards and mentions as a model for sustainable agricultural development. A few examples:
Moving out and beyond
In Central America and Mexico, the inter-connected crises of weak agri-food systems, climate change, conflict, and migration have worsened, while small-scale farmers and marginalized sectors remain mired in poverty.
Capitalizing on its experience in MasAgro, CIMMYT is a major partner in the recently launched CGIAR initiative, AgriLAC Resiliente, which aims to build the resilience, sustainability, and competitiveness of agrifood systems and actors in Latin America and the Caribbean, helping them to meet urgent food security needs, mitigate climate hazards, stabilize vulnerable communities, and reduce forced migration. The effort will focus on farmers in Colombia, El Salvador, Honduras, Mexico, Nicaragua, and Peru.
As described in a 2021 science journal article, CIMMYT also helped create the integrated agri-food system initiative (IASI), a methodology that was developed and validated through case studies in Mexico and Colombia, and leverages situation analysis, model predictions, and scenarios to synchronize public and private action toward sustainable, equitable, and inclusive agri-food systems.
âCIMMYTâs integrated development approach to maize system transformation in Mexico and Colombia laid the foundations for the IASI methodology by overcoming government transitions, annual budget constraints, and win-or-lose rivalries between stakeholders, in favor of equity, profitability, resilience and sustainability,â said Govaerts.
The 2021 Global Agricultural Productivity (GAP) report âStrengthening the Climate for Sustainable Agricultural Growthâ endorsed IASI, saying it ââŠis designed to generate strategies, actions and quantitative, Sustainable-Development-Goals-aligned targets that have a significant likelihood of supportive public and private investment.â
The Coalition on Sustainable Productivity Growth for Food Security and Resource Conservation (SPG Coalition) brings together researchers, non-governmental organizations, and private sector partners to advance a world with greater access to nutritious food and affordable diets. The Coalition recognizes that increasing the productivity of natural resources through climate adaptation and mitigation is instrumental to reaching this goal.
In a recent report, the SPG Coalition provides a path forward for NGOs, research institutions, and government agencies to strengthen agrifood and climate policies. The report contains real-life, evidence-based examples to further the sustainable production and conservation of natural resources, detailing the potential impacts on social, economic, and environmental conditions.
CIMMYT features prominently in the report as a leading organization focused on 4 main areas: climate-smart agriculture, nutrient-use efficiency (NUE), and pest and fertilizer management.
Nutrient-use efficiency and fertilizer management
While chemical fertilizers increase crop yields, excessive or improper use of fertilizers contributes to greenhouse gas emissions (GHG) and increases labor costs for smallholders. Efficient NUE is central to nutrient management and climate change mitigation and adaptation.
In India, CIMMYT, along with the Borlaug Institute for South Asia (BISA), CGIAR Research Centers, and regional partners, tested digital tools like the Nutrient Expert (NE) decision support tool which measures proper fertilizer use for optimized yields and provides nutrient recommendations based on local soil conditions.
The majority of smallholders who applied the NE tool reported higher yields while emitting less GHG emissions by 12-20% in wheat and by around 2.5% in rice as compared with conventional fertilization practices. Farmers also recorded double economic gains: increased yields and reduced fertilizer costs. Wider government scaling of NE could enhance regional food security and mitigate GHG emissions.
The Feed the Future Nepal Seed and Fertilizer (NSAF) project, led by CIMMYT and USAID, advocates for climate-smart agriculture by linking smallholders with improved seed, providing capacity-building programs, and promoting efficient fertilizer use. With a vast network established with the support from the Government of Nepal, NSAF successfully provides smallholders with expanded market access and nutritious and climate-resilient crop varieties.
Climate-smart maize breedingÂ
Since its arrival to sub-Saharan Africa (SSA) in 2016, fall armyworm (FAW) has devastated maize harvests for countless smallholders on the continent. Economic uncertainty caused by unstable yields and climate stressors like drought coupled with this endemic pest risk aggravating food insecurity.
CIMMYT and NARES Partner Institutions in Eastern and Southern Africa are spearheading a robust pest management project to develop, screen, and introduce genetically resistant elite maize hybrids across SSA. South Sudan, Zambia, Kenya, and Malawi have already deployed resistant maize varieties, and eight other countries in the region are projected to release their own in 2023. These countries are also conducting National Performance Trials (NPTs) to increase awareness of host plant resistance for the sustainable control of FAW and to sensitize policymakers on accelerating the delivery of FAW-tolerant maize varieties.
The establishment of FAW screening facilities in Africa permits more rapid detection and breeding of maize varieties with native genetic resistance to FAW, facilitating increased deployment of these varieties across Africa. The sustainable control of FAW demands a rapid-response effort, overseen by research organizations and governments, to further develop and validate genetic resistance to fall armyworms. Achieving greater impact for maize smallholders is critical to ensuring improved income and food security in Africa. It is also paramount for biodiversity conservation and removing labor burden on farmers applying additional synthetic pesticides to prevent further losses by the pest.
âThe SPG Coalition report emphasizes the power of partnership to enhance financial and food security for smallholder communities in the Global South. This is fully in line with the recently launched CIMMYT 2030 strategy. Itâs also an important reminder to assess our strong points and where more investment and collaboration is needed,â said Bram Govaerts, CIMMYT director general.
Climate change is no longer a distant threat but a reality that profoundly affects our lives. Among the most vulnerable regions to climate change, South Asia stands out because it is home to over 100 million farmers and produces over 285 million metric tons of milled rice and 128 million metric tons of wheat (FAO 2020-21). Among 193 countries worldwide, South Asian countries rank in the top quarter for climate risk and are experiencing rising meteorological and climate-related disasters. These pose significant challenges to farmers and the 216 million people in South Asia living in extreme poverty (World Bank, 2018), further jeopardizing their food security and livelihoods.
Considering this, with support from the Bill & Melinda Gates Foundation, the Borlaug Institute for South Asia (BISA) is working with national agriculture research systems in South Asia to develop the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).
The Atlas brings together spatially explicit South Asian data on the nature and evolving patterns of climate hazards. It will assess climate risks using gridded, village-scale analyses and through historical crop yield data and satellite signatures. The Atlas will consider the exposure of smallholder populations, farms and crop and livestock enterprises. It will assess the vulnerability or adaptive capacity of those populations and impacts on the regionâs critical commodities. Importantly, the Atlas will provide a unique set of on-line tools and a portfolio of adaptation options to underpin better decisions regarding investments in agricultural technologies, climate information services, and policies. The project will also focus on building the capacity of concerned stakeholders such as multi-lateral agencies, government bodies, NGOs, and the private sector in the use of Atlas assets, through training materials, tutorials, and periodic workshops. This will enable informed investments and policy decisions to benefit 100 million farmers in South Asian region. For wider use, the Atlas will be embedded online as an open-source, web-enabled and interactive and dynamic tool for easy access by all concerned stakeholders.
Drawing on the expertise and experience of South Asian nations such as Bangladesh, India, Nepal, and Sri Lanka, which have suffered from extreme heat, prolonged droughts, and severe flooding in key crop-producing areas, ACASA represents an example of collaboration and knowledge exchange to reduce farmers’ risks and offer them ways to adapt.
BISA and CIMMYT are pleased to anchor this remarkable collaboration that leverages multi-disciplinary expertise and perspectives to address the complex challenges posed by climate change, linking the detailed characterization of climatic risks with mitigation technologies and policies to meet the needs of diverse stakeholders. The proposed work will contribute actively to the CIMMYT2030 Strategy where one of the 5 impact areas is centered around Climate adaptation and Mitigation. The entire strategy designs a path toward a Food and Nutrition Secure world through science and innovation in the midst of a global climate crisis.
Established in 2011 by CIMMYT and the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) is a non-profit international organization that applies advanced technologies to improve food systems and food security, nutrition, livelihoods, and the environment in South Asia, home to more than 300 million undernourished people.
Adding value to millets can be achieved through various ways, such as incorporating them into baking. By celebrating the International Year of Millets, individuals and communities are encouraged to explore the versatility of millets and contribute to their preservation and use for a healthier and more sustainable future.

The primary focus of this project is on providing technical support to maize and associated crops growers, to develop, validate and implement a working methodology based on a technological menu that responds to the needs of their agri-food systems, aligned with the 2021-2024 government program of the Iguala municipality in Mexicoâs Guerrero state.
The project aims to align with the Sustainable Development Goals: SDG 2 – Zero Hunger; SDG 3 – Good Health and Well-Being for People; SDG 12 – Responsible Consumption and Production; SDG 13 – Climate Action; SGD 17 – Partnerships for the Goals.
Direct project scopes:
The Accelerated Varietal Improvement and Seed Delivery of Legumes and Dryland Cereals in Africa (AVISA) project increased demand-driven, gender equitable and timely access to quality seeds and inputs for small-scale producers by strengthening links between seed producers, farmers and grain aggregators, particularly women and young farmers. Partners included national agricultural research and extension systems (NARES), the Syngenta Foundation for Sustainable Agriculture (SFSA), the Center for Behavior Change Communication (CBCC) and the Tanzania Seed Traders Association (TASTA).
The project, which involved 188 NARES scientists from nine countries in East and Southern Africa (ESA) and West and Central Africa (WCA), tested different impact pathways to improve the scalability of dryland crop innovations. They identified 58 regional market segments for crops such as sorghum, pearl millet, finger millet, groundnut, chickpea and pigeonpea, of which 28 were prioritized for breeding pipelines. Target product profiles were consolidated and priority traits were addressed through a crop health/pathology network. Breeding programs were implemented through shared pipelines, regional trials were conducted and 2,461 farmers participated in tricots.
Efforts included the formation of a cowpea WCA working group, the identification of 26 common bean market segments in East Africa, and the implementation of awareness and demand generation activities using a variety of promotional methods. Data-driven decisions were prioritized, resulting in the creation of breeding informatics teams, quality assurance/control pipelines, and digitization templates.
The project also established governance structures and steering committees for the two target regions in sub-Saharan Africa, as well as operational committees and elected representatives to ensure the functioning and sustainability of the CGIAR-NARES dryland crops network.
In addition, the project targets the Sustainable Development Goals: SDG 2 – Zero Hunger; SDG 13 – Climate Action; SGD 17 – Partnerships for the Goals.

The recently concluded Sorghum Conference brought together researchers, scientists, and experts from around the world to discuss the potential and challenges associated with this resilient crop. Participants shared their key takeaways, experiences, and insights during the event, shedding light on the importance of sorghum and its potential applications.
The International Maize and Wheat Improvement Center (CIMMYT) demonstrated valuable insights and technological advances in a variety of sessions, helping to shape the future of sorghum cultivation and products. CIMMYT has initiated a crop improvement program, known as the Dryland Crop Program (DCP) focusing on sorghum, millet, chickpea, pigeon pea and groundnuts. The program is establishing a network with stakeholders in 17 countries in Africa to collaboratively create, develop, and implement a crop improvement network. This approach will enable CIMMYT and the network to identify suitable products for specific market segments, establish joint breeding pipelines, conduct germplasm testing, and ultimately release and scale up superior seed varieties, thereby improving the quality and yield of these dryland crops, ensuring food security, and promoting sustainable agricultural practices.
Among the speakers and presenters at the conference were six National Agricultural Research Extension Systems (NARES) partners. They presented their findings, addressing critical topics such as adaptation genetics and genomics, climate and environmental change, sorghum yield optimization techniques, and the development of new sorghum products for human consumption.
These are some of their reflections:
Exploring the diverse applications of sorghum
Henry Nzioka from Kenya Agricultural and Livestock Research (KALRO) focused on the resiliency, adaptability, and versatility of sorghum. He appreciated the presentations that highlighted the resilience of sorghum in harsh environments. His research presentation focused on biological control measures and genetic resistance for managing the striga weed in sorghum. His findings aligned with one of the objectives of the conference, which was to develop climate-aware weed management technologies. Nzioka acknowledged the need to bridge the gap between research and the various actors in the sorghum value chain. In addition, he gained valuable knowledge regarding the application of modeling tools and farmer research networks.
âThe knowledge gained here can contribute to the advancement of sorghum-related industries or research. However, its relevance will be country specific as different countries have different preferences and it may also depend on level of technological advancement of respective countries. Countries can be provided with a basket of options from which they can pick the best bet for advancement.â
The importance of collaboration and the potential of sorghum
Charles Bett of KALRO, commended the high quality of the research papers and posters presented and emphasized the event’s timeliness and extensive use of technology. Bett was motivated by the research methodologies employed by other participants and gained new insights that he intends to incorporate into his own work. He summarized the impact of the conference as the realization of sorghum’s enormous potential for reducing food and nutrition insecurity and boosting household incomes. Bett presented on the evaluation of agricultural mechanization levels in the sorghum value chain, which aligned with the conference’s goal of reducing losses and increasing productivity. His reflections and lessons learned include the necessity of a broader coverage of thematic areas at future conferences and the dissemination of existing sorghum technologies to address productivity limitations. âWhile it is important to continue working on technology development, more efforts should be put on dissemination of existing technologies and address productivity depressing constraints.â
Promoting Sorghum as the future crop
Baba Haoua from INRAN, Niger emphasized the future potential of sorghum. The presentations and discussions inspired him and reinforced his belief that sorghum is destined to become a major player in the global agricultural landscape. Haouaâs own research on dual-purpose sorghum perfectly aligns with the objectives of the conference and he left the event knowledgeable and well-connected, eager to continue his work with vigor.
Promoting agroecological transition and regional research on sorghum
Assitan Daou, from the Institut dâEconomie Rurale (IER) in Mali emphasized the suitability of sorghum as a crop for growing populations in varying climates and the significance of an agroecological transition for adaptation to climate change. His poster presentation centered on sorghum cropping systems under rainfed conditions, which aligned with the conference’s goals of increasing crop productivity, adapting to climate variations, and bolstering the resilience of small-scale farmers. He considers the viability of sorghum production, the breaking of boundaries in the sorghum value chain, and the factors driving future sorghum demand. The exchange with other researchers, as well as the opportunity to improve his communication skills and establish contacts for future collaboration, satisfied Daou’s expectations for the conference. He learned new research techniques, such as crop modeling, and believes the knowledge he gained at the conference will advance sorghum-related industries and research.
Recognizing the resilience and potential of sorghum
Rekiya Abdoulmalik, from the Institute of Agriculture Research (IAR) in Nigeria, presented about the stability evaluation of recently released dwarf sorghum lines, which aligned with the conference’s objective of revealing the genetic potential of sorghum in various environments. The conference motivated her to explore new ideas and directions for her research, particularly regarding the significance of root system architecture for drought resistance. She left the conference with new knowledge and a vision for climate-smart sorghum varieties that can meet food and feed requirements.
Exposing the economic worth of sorghum
Alex Zongo, from the Institut de l’Environnement et des Recherches Agricoles (INERA) / CNRST in Burkina Faso, was inspired by the conference to shift the focus of his research to understanding the value of sorghum for inclusive and sustainable agriculture. He gained a deeper understanding of sorghum’s uses, such as in baking, brewing, and animal feed. Zongo was inspired by the conference to investigate the economic contribution of sorghum and increase stakeholder awareness. âNew knowledge shows that crop association (which mobilizes sorghum to a greater extent) helps to stabilize crop yields through soil fertility management. We therefore need to study its economic contribution.â
