The Minister of Agriculture and Rural Affairs for China, Tang Renjian, visited CIMMYT headquarters on Thursday, 11 January, along with dignitaries from the Ministry of Agriculture and Rural Affairs (MARA) and the Embassy of China. Tang, the former governor of Gansu province in China, attended the site with the aim of building on collaborative scientific work between his country and CIMMYT through the Joint Laboratory for Maize and Wheat Improvement in China.
CIMMYT was delighted to host Tang to showcase the benefits of the CIMMYT-China relationship for wheat and maize, and to identify opportunities for sustained collaboration. The highly regarded minister was able to hear about work including genetic analysis service for agriculture and methods to close the gap between farmers and research, as well as to observe CIMMYTâs facilities and field experiments. The meeting laid the foundations for potential future CIMMYT-China projects in areas such as germplasm exchange, molecular breeding, climate-resilient technology, and training.
Bram Govaerts, director general of CIMMYT, said, âShowcasing our science to Tang is an exciting chance for CIMMYT and China to grow what is already a fruitful partnership, impacting millions of people globally.â
Exemplifying impactful global partnerships
Since 1974, the CIMMYT-China relationship has improved the lives of millions of people via numerous evidence-based scientific projects, with support from the Chinese Academy for Agricultural Sciences (CAAS). Through five decades of partnership, the collaboration has resulted in up to 10.7 million additional tons of wheat for Chinaâs national output with a value of US $3.4 million.
CIMMYTâs contribution to Chinaâs wheat and maize is significant. In terms of wheat, 26% of wheat grown in China has been derived from CIMMYT germplasm since the year 2000, with Chinese scientists adding more than 1,000 accessions to the CIMMYT gene bank. CIMMYT maize varieties have been planted on more than 1 million hectares in China, with the partnership responsible for the release of 13 commercial varieties.

More recently, scientists have played an important role in the free exchange of germplasm between China and countries in Africa, which will help to mitigate against any gene pool loss caused by climate-induced extreme weather events and enable the development of more resilient crop varieties.
Tang said, âWitnessing first-hand the work of CIMMYTâs scientists in Mexico is inspiring. We look forward to exploring further how we can build on the excellent relationship between China and CIMMYT to address global agricultural challenges.â
Govaerts said, âWe hope that this partnership continues in order to address the need for nutritious crops and to develop innovative solutions for smallholder farmers.â
The collaboration between CIMMYT, the Regional Wheat and Maize Research Center RWMRC and the Krishi Gobeshona Foundation is set to significantly boost lentil production in Bangladesh’s Rajshahi region. By introducing high-yielding lentil varieties and modern farming practices, and offering farmer support through training and resources, this initiative aims to capitalize on underused lands, enhance food security, and reduce imports, promising a substantial increase in the local lentil supply.
CIMMYT advances agricultural mechanization to boost smallholder farming, targeting efficiency and inclusivity. Addressing challenges like financial access and market collaboration, it fosters mechanization scaling through initiatives like MasAgro in Mexico, MasAgro Africa and tools like Scaling Scan. This approach aims to rejuvenate agriculture for youth, under the guidance of director general Bram Govaerts, ensuring sustainable and globally inclusive agricultural systems.
CIMMYT has introduced 20 heat-resistant maize hybrids in South Asia, including Pakistan, to boost resilience against climate change and support smallholder farmers. This breakthrough, achieved after a decade of collaboration with regional research institutes and seed companies, aims to secure food supplies amid rising temperatures. Through initiatives like Pakistan’s Agricultural Innovation Programme, CIMMYT is committed to enhancing maize production and food security, showcasing the power of scientific innovation in addressing global agricultural challenges.
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 agricultureâs 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 agricultureâdiverse 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 CIMMYTâs contribution to COP 28, Bram Govaerts, CIMMYTâs 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.
âOur 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,â 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 tomorrowâs climatic and environmental conditions.
âOur 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,â 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,â 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.
âDrought-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,â 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: Â conservation agriculture, cropping system diversification and site-specific nutrient management and their impact on food production, climate change adaptation and mitigation.
âAs the science continues to develop, we need to harness digital capacity to co-create sustainable solutions alongside local, indigenous knowledge,â said Sapkota. âWhile 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.â
CIMMYT-BISA-ICAR organized a two-week training program on conservation agriculture (CA) to demonstrate how CA can be a sustainable farming method and an effective tool for farmers and scientists in both irrigated and rainfed systems to manage agrifood system risks.

The training was jointly conducted by CIMMYT in collaboration with the Borlaug Institute for South Asia (BISA) and the Indian Council of Agricultural Research â Central Soil Salinity Research Institute (ICAR-CSSRI). It was held at the BISA research facilities in Jabalpur and Ludhiana, India, and ICAR-CSSRI in Karnal, India, from 9 December to 24 December 2023.
Creating resilient agrifood systems
Conservation agriculture is an ecosystem approach to agricultural land management based on three interrelated principles: minimal soil disturbance, permanent soil cover, and crop diversification. It helps farmers boost yields, regenerate natural resources, reduce cultivation costs, and create resilient production systems. This helps protect the environment and enhance livelihoods of rural populations, especially in the Global South.
In this region, the rural population depends on natural resources â land, freshwater, and coastal fisheries â for survival. However, the depletion of soil fertility, scarcity of water resources, exacerbated by environmental pollution and climate change-induced stresses, prove challenging to irrigated and dryland agriculture production systems. This puts agrifood systems in South Asia and Africa under tremendous pressure.
Despite the benefits, farmers face significant barriers to adopting CA practices. Lack of knowledge and skills, limited access to appropriate seeds and equipment, lack of policy support, under-developed value chains, and non-acceptance of the fact that CA can yield better results and long-term benefits often prevents farmers from adopting CA practices. Hence, capacity development is vital for the adaptation and scaling of CA-based technologies among smallholder farmers.
To cater to these needs, an Advanced Course on Conservation Agriculture in Asia â a Gateway for Sustainable and Climate Resilient Agrifood Systems was launched in 2010. Later, it was expanded to North Africa. The course links scientific advances and multidisciplinary approaches for upgrading the skills of participants for sustainable intensification and diversification of production systems, enhancing resilience, and conserving natural resources. Since its inception, this training series has directly benefited about 220 researchers, development personnel, and policymakers from 20 countries.
The 12th edition of the training in India saw mid-career researchers and development officers from Morocco, Egypt, Bangladesh, and India participate. Approximately 40% of the attendees were women.
Highlights from the India training programÂ
The inaugural session commenced on 9 December 2023 at the NASC Complex in New Delhi, India. Present at the opening ceremony were chief guest S.K. Chaudhari, deputy director general – Natural Resource Management, ICAR; Arun Joshi, CIMMYT regional representative and managing director of BISA; and Mahesh K Gathala, course coordinator, and Alison Laing, agroecologist from CIMMYT in Bangladesh.
During the welcome address, Joshi informed that CIMMYT and BISA are committed to capacity development of national partners around the world. Chaudhari emphasized the effectiveness in facilitating innovations in CA management. âUnder increasing climate variability and change, the need to manage agronomic risks is even more significant and CA is an effective tool for farmers and scientists in irrigated and rainfed systems,â he said.
Participants were introduced to the genesis, background, and objectives of the course by Gathala. Resource persons across diverse disciplines informed the participants about innovative and cutting-edge research in all aspects of CA in both irrigated and dryland cropping systems, including advanced agronomy; mechanization; farm, soil, and water interactions; plant protection, health and crop breeding; climate resilience; farming systems simulation and analysis; agribusiness management; womenâs empowerment and gender equity; and agricultural extension and out-scaling. Participants also gained practical knowledge and skills at the BISA research stations where extensive trainings were conducted under the guidance of Ravi Gopal Singh, Raj Kumar, and Lalit Sharma, course coordinators. They organized a series of sessions, along with the hands-on training, at the CA experiment farm in the BISA research facilities. Participants also toured 500 acres of farms at each of the locations. They visited farm facilities such as wheat research trials, molecular laboratory, precision nitrogen nutrition facility, seed processing unit, and farm machinery section.

The group also visited ICAR-CSSRI facilities in Karnal where R.K. Yadav, director, ICAR- CSSRI, welcomed the participants and highlighted the international and national collaboration activities at CSSRI and how long-term experiments on CA are managing and generating science-based evidence to inform policy and capacity building.
Special visits were organized to farm machinery manufacturers in the region to facilitate industry-participant interactions. Participants visited the Landforce factory at Amargarh, a leading manufacturer of all ranges of farm equipment – from seeding to harvesting and processing. This firm is equipped with the latest manufacturing facilities and techniques such as robotic welding, assembling and automated paint. Later, the group visited the National Agroindustry at Ludhiana, a top manufacturer of planters including bed planters, zero till drills, Happy Seeders, pneumatic and precise planters.
Finally, participants were taken to the farmer fields to interact with the farmers and observe the impact first-hand. They met with a progressive farmer group at Karnal who shared their experiences of practicing CA for the last few years. Post these visits and learning sessions, a closing ceremony was organized at CSSRI at Karnal which was chaired by R.K. Yadav and attended by special guests Rajbir Singh, ADG-ICAR and ML Jat, global director RFFS, ICRISAT. âThe session on CA machinery was very helpful and carbon credit was an essential part of our learning. We also got an opportunity to exchange our ideas and experiences with researchers from Morocco, Egypt, and Bangladesh. We sincerely thank the organizers for making us confident and technically smart CA personnels,â said a participant from India.

Much has changed since many CIMMYT scientists attended university. In the past decades, the STEM field was predominantly male, with far less representation from marginalized groups and communities. Challenged by societal prejudices, only a handful of young women pursued STEM subjects, which further influenced career choices made by them, reinforcing the gender gap.
The gender gap in STEM is still significant, but times are changing. âAt CIMMYT, we are deeply committed to promoting the voice of youth, marginalized communities, and women to improve the rigor of science for sustainable development. This includes investment in mentorship, learning from champions and pioneers, and appropriate performance assessment guidelines,â said Program Director of CIMMYT’s Sustainable Agrifood Systems, Sieglinde Snapp. âIt is a long journey with bumps along the way, but I am proud to be in solidarity with the Global South, where we champion gender and social inclusion every day.â
On International Day of Women and Girls in Science 2024, five CIMMYT scientists who inspire, support, and open doors for many young women and underrepresented groups with their scientific work and pay-it-forward commitment share their motivation behind charting a career in STEM and encourage more young women and make the field more inclusive.

Hailing from a farming family, Beyhan Akin was always surrounded by the beauty and potential of agriculture. She wished to contribute to her farming community, so 35 years ago, she joined CIMMYTâs wheat research program. Akin reminisced about her early days, how there were few women scientists, and the realization that if she succeeded, she could motivate more to follow in her footsteps.
“Agriculture science is expanding beyond core crop science with huge potential for interdisciplinary research and innovation. I hope young women students and scientists get the opportunity to pursue and excel in these fields. Increased advocacy and investmentâgrants, fellowshipsâat an institutional level is crucial to motivating and supporting the aspirations of women in science,â said Akin. âIt might have taken a long time for women scientists like us to be in positions of influence, but I hope we can ensure the path is far less challenging today for these young women pursuing agriculture science/STEM.â

“Search out mentors. Donât be afraid to either ask for help when you need it or to promote your achievements. And build networks,â advises Alison Laing to young women scientists starting in the field. Based in Bangladesh and working across South and Southeast Asia for over 15 years, Laing hopes that girls have opportunities to choose science education and become women with rewarding careers in fields that interest them, especially in non-traditional STEM disciplines.
Laing remembers how her mentor early in her career, the late John Schiller, a rice agronomist at the International Rice Research Institute (IRRI), encouraged her enthusiasm for learning and research. âHe taught me so much about doing research in Southeast Asia, and I am indebted to him for his motivation and support in showing me how rewarding and interesting a scientific career can be.â She hopes other young students and scientists will have such mentors in their lives.
Sabina Tiwari, assistant research associateÂ

Fascinated by nature, plants, and how they thrive in diverse environments, Sabina Tiwariâs journey in science led her to become a plant breeder. âThe indefinite potential of agriculture to improve lives made me realize how powerful agricultural science can be. This led to the motivation that I could create a positive difference in the world by being part of crop science and technology while working alongside great scientific minds, both men and women. Today, to young girls aspiring to make a difference in the world, I recommend they empower their cause through science and innovations.”
According to Tiwari, mentorship programs, internships, and job-shadowing experiences that helped her career must be extended to young women to gain practical exposure and knowledge of the possibilities in agriculture science.

For Mazvita Chiduwa, a career in agriculture science has been rewarding. âI love the adventure involved in discovery in agriculture. I am inquisitive, and this career allows me to ask questions and seek answers,â said Mazvita.
Chiduwa believes society needs to embrace the participation of women and girls in STEM education and careers and that stereotypes about women not being cut out for STEM, prevalent even today, must be done away with.
To young girls and women aspiring for a career in STEM, Chiduwa says, âGo for it. There is a need for your uniqueness to contribute a wholesome solution to our worldâs challenges.â
Luisa Cabrera Soto, research associate Â

“A feminine perspective and approach are needed to enrich research,â reminds Luisa Cabrera Soto. âIn a society where almost half of the members are female, I hope equity and inclusion will help improve under-representation in STEM.â
According to Cabrera, it is essential that women in science continue to challenge the gender prejudices and stereotypes that still exist. âDon’t let the spark of your curiosity go out. As a food science professional, I can say that there are still discoveries to be made and, through it, the probability of finding innovative solutions to global challenges such as food security.â
Researchers, including Sieg Snapp from CIMMYT, are pioneering crops that fertilize themselves by harnessing atmospheric nitrogen. This revolutionary breakthrough promises to slash synthetic fertilizer use, combat environmental damage, and usher in a new era of sustainable agriculture. A leap towards greener, self-sustaining food production is on the horizon.
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.
With generous support from USAID, CIMMYT, in collaboration with the lead organization World Food Programme and partner organizations SNV, Tree of Life, and MTDC, has significantly enhanced climate resilience in Zimbabwe through the promotion of conservation agriculture practices under the Zambuko Livelihoods Initiative initiated, since 2020.
Climate change poses a threat to yields and food security worldwide, with plant diseases as one of the main risks. An international team of researchers, surrounding professor Senthold Asseng from the Technical University of Munich (TUM), has now shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.
With a global cultivation area of 222 million hectares and a harvest volume of 779 million tons, wheat is an essential food crop. Like all plant species, it is also struggling with diseases that are spreading more rapidly compared to a few years ago because of climate change. One of these is wheat blast. In warm and humid regions, the fungus magnaporthe oryzae has become a serious threat to wheat production since it was first observed in 1985. It initially spread from Brazil to neighboring countries. The first cases outside of South America occurred in Bangladesh in 2016 and in Zambia in 2018. Researchers from Germany, Mexico, Bangladesh, the United States, and Brazil have now modeled for the first time how wheat blast will spread in the future.

Regionally up to 75% of total wheat acreage affected
According to the researchers, South America, southern Africa, and Asia will be the regions most affected by the future spread of the disease. Up to 75% of the area under wheat cultivation in Africa and South America could be at risk in the future. According to the predictions, wheat blast will also continue to spread in countries that were previously only slightly impacted, including Argentina, Zambia, and Bangladesh. The fungus is also penetrating countries that were previously untouched. These include Uruguay, Central America, the southeastern US, East Africa, India, and eastern Australia. According to the model, the risk is low in Europe and East Asiaâwith the exception of Italy, southern France, Spain, and the warm and humid regions of southeast China. Conversely, where climate change leads to drier conditions with more frequent periods of heat above 35 °C, the risk of wheat blast may also decrease. However, in these cases, heat stress decreases the yield potential.

Dramatic yield losses call for adapted management
The affected regions are among the areas most severely impacted by the direct consequences of climate change. Food insecurity is already a significant challenge in these areas and the demand for wheat continues to rise, especially in urban areas. In many regions, farmers will have to switch to more robust crops to avoid crop failures and financial losses. In the midwest of Brazil, for example, wheat is increasingly being replaced by maize. Another important strategy against future yield losses is breeding resistant wheat varieties. CIMMYT in collaboration with NARs partners have released several wheat blast-resistant varieties which have been helpful in mitigating the effect of wheat blast. With the right sowing date, wheat blast-promoting conditions can be avoided during the ear emergence phase. Combined with other measures, this has proven to be successful. In more specific terms, this means avoiding early sowing in central Brazil and late sowing in Bangladesh.
First study on yield losses due to wheat blast
Previous studies on yield changes due to climate change mainly considered the direct effects of climate change such as rising temperatures, changing precipitation patterns, and increased CO2 emissions in the atmosphere. Studies on fungal diseases have so far ignored wheat blast. For their study, the researchers focused on the influence of wheat blast on production by combining a simulation model for wheat growth and yield with a newly developed wheat blast model. Environmental conditions such as the weather are thus included in the calculations, as is data on plant growth. In this way, the scientists are modeling the disease pressure in the particularly sensitive phase when the ear matures. The study focused on the influence of wheat blast on production. Other consequences of climate change could further reduce yields.
The Excellence in Agronomy Initiative, supported by CGIAR centers including CIMMYT, is driving significant advancements in sustainable farming. Highlighting a case from Cambodia, this initiative exemplifies how innovative agronomy, adapted for climate resilience, is transforming agriculture globally. CIMMYT’s role in this collaborative effort underscores its commitment to sustainable agricultural development and climate change adaptation.
In a significant breakthrough for Somalia’s agriculture, Filsan Seed Company and CIMMYT have introduced Siman, a high-yielding hybrid maize. Developed under CIMMYT’s Stress Tolerant Maize for Africa program, Siman marks a new era of enhanced productivity and food security in Somalia. Stay tuned for more on this game-changing agricultural innovation.
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.
