As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s 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 world’s 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.
CIMMYT is collaborating in a major project in Uganda, led by NaSARRI, to fortify sorghum with the essential nutrients iron and zinc to combat malnutrition in East Africa. Over four years, this partnership, which includes universities and research organizations, aims to improve the nutritional value of sorghum for human and livestock consumption using conventional breeding. This effort reflects CIMMYT’s commitment to sustainable agriculture and food security, with a focus on improving crop quality and safety to support healthier communities and livestock.
The 2023 UN Climate Change Conference (COP 28) took place from November 30 to December 12, 2023, in Dubai, UAE. The conference arrived at a critical moment when over 600 million people face chronic hunger, and global temperatures continue to rise at alarming rates. CIMMYT researchers advocated for action into agriculture’s mitigating role in climate change, increasing crop diversity, and bringing the tenets of sustainability and regenerative agroecological production systems to a greater number of farmers.
Directly addressing the needs of farmers, CIMMYT proposed the creation of an advanced data management system, training, and protocols for spreading extension innovations such as digital approaches and agronomic recommendations to farmers via handheld devices to harmonize the scaling in Africa of regenerative agriculture—diverse practices whose outcomes include better productivity and environmental quality, economic feasibility, social inclusivity, and nutritional security.
CIMMYT presented research showing that in times of fertilizer shortages, targeting nitrogen supplies from inorganic and organic sources to farms with minimal access to nitrogen inputs can improve nitrogen-use efficiency and helps maintain crop yields while limiting harm from excesses in fertilizer use. Examining how food production is driving climate change, CIMMYT promoted ways to lessen climate shocks, especially for smallholder farmers who inordinately suffer the effects of climate change, including rising temperatures and extended droughts. Improved, climate-resilient crop varieties constitute a key adaptation. Boosting farmer productivity and profits is a vital part of improving rural livelihoods in Africa, Asia, and Latin America.
When asked about CIMMYT’s contribution to COP 28, Bram Govaerts, CIMMYT’s director general, highlighted the inclusion of agriculture in the COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action as part of various potential solutions for climate change, an effort that CIMMYT supported through advocacy with leaders and government officials.
“Our participation addressed some of the pressure points which led to this significant recognition. It further cleared our role as an active contributor to discussions surrounding the future of food and crop science,” said Govaerts.

Hearne explained the process that characterizes plant DNA to identify the ideal, climate-adaptable breeding traits. This classification system also opens the door for genetic modeling, which can predict key traits for tomorrow’s climatic and environmental conditions.
“Our thinking must shift from thinking of gene banks to banks of genes, to make vibrant genetic collections for humanity, opening up genetic insurance for farmers,” said Hearne.
Working towards a food system that works for the environment
With an increased strain on food production, sustainability becomes critical for long-term human and environmental health. Sarah Hearne and Tek Sapkota, agricultural systems and climate change senior scientist, from CIMMYT participated in a panel discussion: Responsible consumption and sustainable production: pathways for climate-friendly food systems. They shared how progress in genetic innovation and fertilizer use can contribute to sustainable consumption and a resilient food system.
Fertilizer use remains highly skewed, with some regions applying more fertilizer than required and others, like sub-Saharan Africa, not having sufficient access, resulting in low crop yields. However, to achieve greater food security, the Global South must produce more food. For that, they need to use more fertilizer. Just because increased fertilizer use will increase greenhouse gases (GHGs) emissions, institutions cannot ask smallholder farmers not to increase fertilizer application. Increased GHGs emission with additional fertilizer application in low-input areas can be counterbalanced by improving Nutrient-Use Efficiency (NUE) in high-output areas thereby decreasing GHGs emissions. This way, we can increase global food production by 30% ca with the current level of fertilizer consumption.

“This issue needs to be considered through a holistic lens. We need to scale-up already proven technologies using digital extensions and living labs and linking farmers with markets,” said Sapkota.
On breeding climate-resilient seeds, Hearne addressed whether farmers are accepting new seeds and how to ensure their maximum adoption. Hearne detailed the partnership with CGIAR and NARS and the numerous technologies advancing the selection of ideal breeding traits, considering shortened breeding cycles, and responding to local needs such as heat or flood tolerance, and traditional preferences.
“Drought-tolerant maize, developed by CIMMYT and the International Institute of Tropical Agriculture (IITA), has benefited over 8 million households in sub-Saharan Africa, which proves that farmers are increasingly receptive to improved seeds. With a better selection of appropriate traits, we can further develop and distribute without yield penalties,” said Hearne.
Regenerative and agroecological production systems
Researchers have studied regenerative and agroecological production systems for decades, with new and old research informing current debates. These systems restore and maintain ecosystems, improving resource use efficiency, strengthening resilience, and increasing self-sufficiency. In his keynote presentation, Sapkota presented 3 examples of regenerative agriculture and agroecological systems: conservation agriculture, cropping system diversification and site-specific nutrient management and their impact on food production, climate change adaptation and mitigation.
“As the science continues to develop, we need to harness digital capacity to co-create sustainable solutions alongside local, indigenous knowledge,” said Sapkota. “While we should continue research and innovation on cutting-edge science and technologies, we should also invest in knowledge sharing networks to spread access to this research; communication is fundamental for further adoption of these practices.”
In Busia, Chris Ojiewo from CIMMYT and partners are spearheading the adoption of high-yielding millet varieties to boost food security and tackle climate change. This initiative aims to equip farmers with quality seeds and modern farming techniques, ensuring the sustainable cultivation of millet, a crop resilient to harsh climates.

Dr. Ravi Prakash Singh, associated with CIMMYT, is awarded the Padma Shri. He’s recognized for his global impact in agricultural science, notably developing over 730 climate-resilient, high-yield wheat varieties, benefiting small-holder farmers.
The livestock sub-sector is one of the most important arms of the agricultural sector, contributing to the livelihoods of 70% of Zimbabwe’s rural population. Sustainable livestock production depends on the maintenance of healthy and productive animals which requires paying particular attention to the problems of both endemic and introduced animal diseases and zoonotic. Climate relevant livestock production practices such as fodder management and conservation, water harvesting, and manure management have been identified as solutions to increasing livestock productivity.
The Livestock Production Systems in Zimbabwe (LIPS-Zim) project, funded by the European Union (EU) focuses on increasing agricultural productivity in Zimbabwe’s semi-arid, agro-ecological regions IV and V. Led by the International Livestock Research Institute (ILRI) and in partnership with CIMMYT, the French Agricultural Research Center for International Development (Cirad) and the University of Zimbabwe (UZ), LIPS-Zim is working in 10 districts of Zimbabwe, i.e. Matabeleland South Province (Beitbridge and Gwanda districts), the parched Matabeleland North Province (Binga, Hwange and Nkayi districts), Midlands (Gokwe North district), Masvingo (Chiredzi and Zaka districts), Manicaland (Buhera district) and Mashonaland East (Mutoko district). LIPS-Zim is conducting research that seeks to increase livestock feed productivity and well as reducing diseases and mortality of livestock.
Main objectives
Core to the project is to increase the adoption of climate-relevant innovations (e.g feeding) in livestock-based production systems and improve the surveillance and control of livestock diseases. CIMMYT’s main thrust in this project is based on the recognition that at least 50% of the arable land area in semi-arid region IV and V of Zimbabwe is still put to maize despite extension recommendations for farmers to grow the more resilient small grains in those regions. Given the above, and to address their food and feed needs, farmers in those regions need drought-tolerant and nutritious maize varieties that are resilient in those dry environments. CIMMYT’s work is thus focusing on testing the feed value of these nutritious and drought tolerant maize varieties when intercropped with various legumes such as mucuna, cowpea, lab-lab and pigeonpea. CIMMYT is also testing the later, along with climate smart production techniques such as conservation agriculture and water harvesting practices.
CIMMYT’s development and release of six new wheat varieties in Ethiopia, aimed at combating rust diseases and increasing yields, underscore its pivotal role in advancing agricultural self-sufficiency and productivity in the country. These varieties, covering the majority of Ethiopia’s wheat cultivation area, highlight CIMMYT’s significant contribution to enhancing food security and agricultural resilience.

In Zambia, smallholder farmers obtain their seed from a variety of sources. Over 75 percent of farmers in Zambia have adopted certified maize seed and about 30 percent in southern Africa, overall. The private sector has been instrumental in creating demand for certified and timely delivery of seed to remote areas, and the Government of Zambia’s Farmer Input Support Programme (FISP) has largely contributed to better accessibility to certified seed for farmers. In 2022–2023, of the three million registered smallholder farmers in Zambia, more than one million accessed certified seed through FISP.
Afriseed is a seed company in Zambia that has been gaining ground in local seed markets. It has emerged as a catalyst for helping smallholder farmers transition to new, high-yielding legume varieties. Afriseed provides solutions to help smallholders increase their agricultural productivity with improved seed varieties of cereals and legumes and assist them with technology transfer. The company aims to increase the food security and incomes of Zambia’s smallholder farming community, which accounts for 90 percent of agricultural output in the country. During the 2022–2023 farming season, a critical turning point was reached when Afriseed became a partner in the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, a two-year project under CIMMYT, with the aim of scaling-up production of certified seed varieties of soybean and common bean.
Under the partnership, Afriseed promotes the cultivation of improved legume seed through a smallholder farmer seed multiplication approach. By engaging with practicing smallholder farmers and signing grower contracts, basic seeds are multiplied into certified seed for soybean and common bean. Certified seed is a known variety produced under strict seed certification standards to support varietal purity. In collaboration with the Seed Control and Certification Institute (SCCI), the country’s national seed authority, contracted farmers received training on climate-smart agricultural techniques and seed production guidelines. Through extension services to seed growers, smallholder farmers can adhere to the seed production guidelines set out in the National Seed Act to ensure the quality of certified seed produced.

Afriseed has invested more than USD 335,000 toward supporting the production, aggregation, and processing of 317 t of certified climate-smart legume seeds—265 metric tonnes (MT) for soybean and 52 MT for common bean. Data have shown that the seeds were aggregated from 313 smallholder seed growers, 40 percent of whom were women, in Zambia’s Eastern Muchinga, Copperbelt and the Northern provinces. Seed aggregation improves access to quality seed varieties, increases crop yields and incomes, enhances integration into value chains, and creates market links for smallholder farmers.
Notable progress has been made with the contracted farmers, who have applied improved crop management practices and technologies on more than 600 ha of land to produce the seed. With this encouraging progress, Afriseed intends to scale up its last-mile seed distribution strategy to reach and directly help an estimated 35,000 underserved rural smallholder farming households with improved legume seeds in the 2023–2024 cropping season.
AID-I is one of the ways in which Feed the Future, the U.S. Government’s global food security and hunger initiative led by USAID, is taking immediate action to help cushion the blow of high fuel and fertilizer prices on farmers. One of the project’s initial actions is to strengthen local seed systems so that agribusinesses can reach smallholder farmers with a diversity of improved seeds varieties, including climate-resilient and more nutritious varieties for maize and legumes.
CIMMYT’s involvement in the TELA Maize Project has been instrumental in the development of new drought-tolerant and pest-resistant maize varieties, recently released by Nigeria’s Federal Government. This initiative, aimed at enhancing food security and agricultural productivity, underscores CIMMYT’s commitment to agricultural innovation and global collaboration in biotechnology.

More than 1,300 smallholder farmers, across the Mwenezi and Masvingo districts of Zimbabwe, braved the hot morning sun to attend the fourth edition of the seed and mechanization fair organized by CIMMYT and partners in early October 2023. The event, themed “Harnessing improved seed and mechanization for climate resilience,” saw these farmers from all walks of life—first timers to past attendees—eager to participate, learn and explore the innovations on display.
Evolving over time, the seed and mechanization fair has continued to serve as a strategic platform to connect local farmers with private sector companies while enhancing the uptake of drought-tolerant maize varieties and scale-appropriate machinery. “Since 2020, CIMMYT-driven seed fairs have encouraged smallholder farmers in semi-arid areas, to grow the right seed at the right time to avoid any shortcomings due to unpredictable of weather patterns,” said Christian Thierfelder, principal cropping systems agronomist at CIMMYT.
Fast approaching farming season
El Niño continues to pose a threat to farmers especially in semi-arid areas such as in Mwenezi district situated in southern Zimbabwe and Masvingo district in south-eastern Zimbabwe which are drought prone areas characterized by high temperatures, rainfall deficit, among other challenges. Through the seed fairs, CIMMYT, a consortium member of the World Food Program projects, R4 Rural Resilience and the Zambuko Livelihoods Initiatives supported by the Swiss Agency for Development and Cooperation (SDC) and USAID, has been at the forefront, advocating for and inspiring local farmers to buy and use seed varieties suitable for their environment, while encouraging farming as a business. In addition, the regional project Ukama/Ustawi Diversification in East and Southern Africa joined efforts to support farmers in income diversification from pure cereal-based systems to more diversified cereal-legume and mechanized farming systems.
“I believe this is the right function at the right time as we prepare for the next farming season. From this event, we anticipate that farmers will say, ‘Yes we have received new technology, yes we have knowledge on new varieties, yes we have information about the weather forecast’. We now have confidence that farmers are well-equipped and ready for the season to achieve the Zimbabwe Vision 2030,” said Isaac Mutambara, district development coordinator from Mwenezi.
Building resilience with drought-tolerant varieties
Amid climate change, equipping farmers with climate-smart knowledge and the right seed varieties has been central to the seed fairs. Working hand in hand with the government, CIMMYT has been breeding drought tolerant, orange maize with high nutritional value. “We encourage the growing and consumption of crops with nutritional value for household food security. Furthermore, we have different varieties of orange maize which are drought-tolerant,” said Thokozile Ndhlela, maize line development breeder. In addition, CIMMYT as part of HarvestPlus, has been encouraging the growing and consumption of nutritious NUA45 beans which are high in iron and zinc.
Mechanizing agriculture

The joint participation of the USAID funded ‘Feed the Future Zimbabwe Mechanization and Extension activity’, helped to emphasize the importance of transforming smallholder agriculture through scale-appropriate equipment. At the event, machinery manufacturers such as Prochoice, Kurima and Mahindra showcased cutting-edge machinery, designed to ease farming operations. These companies showed live demonstrations of two-wheel tractors, basin diggers, multiple crop threshers amongst others, effectively emphasizing the benefits of scale-appropriate mechanization. The innovations on display demonstrated the unwavering dedication of the private sector towards supporting farmers and driving agricultural innovation. “It has been a truly exciting opportunity operating the peanut sheller, while appreciating the different machinery in live action. I will consider buying this machine as it reduces the added burden of shelling and processing,” said Lungiwe Nyathi, a local farmer from Mwenezi.
Partnerships for growth
Various seed companies, including AgriSeeds, SeedCo, Farm and City, Super Fert, National Tested Seeds, Intaba Trading, Sesame for Life and K2, marketed appropriate seed varieties that ensure bumper harvests. Sales of seed, fertilizer and other inputs were high, with the total value of sales reaching US6,450. Vouchers were distributed to farmers who made high cash purchases of seeds. “I bought 45kgs of seed which I believe is a great start, and I am happy that I do not have to pay extra money for transporting the seed to my home,” said Martha Chiwawo, a farmer from ward 16 in Masvingo.
The fairs would not be complete without CIMMYT partners. While Zambuko Livelihoods Initiative shared their expertise in the district, SNV has been encouraging sustainable savings and lending schemes among farmers to purchase machinery while facilitating market access and reducing post-harvest losses. The World Food Programme (WFP) encouraged farmers to become resilient and self-sufficient through valuable knowledge and skills to improve their lives. In addition, the Mwenezi Development Training Centre (MDTC) focused on encouraging small livestock which are adaptable to the area. Additional partners Cesvi and Sesame for Life, who both operate in ward 6 of Mwenezi district, participated in the seed fairs for the first time. Both partners advance the production of high value crops—paprika and sesame—which have a ready export market and favorable prices for smallholder farmers. Government extension departments showed strong support while researchers from the Makoholi Research Station in Masvingo used the opportunity to talk to farmers about their research initiatives.
As the day came to an end, farmers were brimming with excitement and ready to embark on the season ahead with purchased, improved seed and a wealth of knowledge on innovative conservation agriculture practices. The event proved to be an invaluable opportunity for uniting farmers, government, seed companies, and partners in a shared mission to promote sustainable farming practices and ensure food security.

Maize is a vital crop in Zambia and Tanzania, both for farmers’ economic livelihoods and for delivering nutrients and sustenance to a large group of people. But maize is threatened by climate change, like more severe droughts, and from pests like fall army worm (FAW), which can completely devastate farmers’ fields.
Against this backdrop of looming threats, CIMMYT, as part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is partnering with the Zambia Seed Company Limited (Zamseed) to distribute seeds that are drought tolerant and resistant to the ravages of FAW. And because maize is a staple of many people’s diets, CIMMYT and Zamseed are also developing and distributing maize varieties enhanced with vitamin A.
To uphold maize variety integrity, CIMMYT and Zamseed are engaged in the capacity building of quality assurance and quality control for local stakeholders.
CIMMYT’s engagement with Zamseed involves efforts to popularize high yielding, drought-tolerant, and vitamin enhanced maize varieties in Zambia and Tanzania. Some of these efforts include demonstrations of the new varieties, field days held at different stages of maize development, and deliberate engagement of women throughout the entire seed selection, planting and harvesting effort.
“Our partnership with Zamseed started in October 2022,” said Ir Essegbemon Akpo, a CIMMYT maize seed systems specialist. “It has been a fruitful collaboration, delivering significant outputs to thousands of farmers in Zambia and Tanzania.”
To date, Zamseed has held 300 and 500 demonstrations in Tanzania and Zambia, respectively. The company has held many field days at the demonstration sites to showcase drought tolerant and vitamin A enhanced maize to hundreds of small-scale farmers.
“We have witnessed many farmers who visited the demonstration activities who are excited to see the new high yielding and drought tolerant varieties,” said Amsal Tarekegne of Zamseed.
Seeded by funds from the AID-I project, Zamseed is producing 60kg of Early Generation Seed (EGS) of parents of a FAW-tolerant hybrid maize variety. The company plans to produce 200kg of this hybrid for commercialization and launch in 2024.
To ensure that seeds delivered to farmers are of the highest quality, CIMMYT is working with Zamseed to develop quality assurance and control frameworks, involving genotyping of selected seeds at various times during the seed multiplication and distribution process.
Zamseed has been servicing the requirements of farmers in the sub-Sahara region since 1980, focusing on products that will enhance the profitability of the small-scale farmer and ensure household food security.
