On July 17-18, 2023, 87 wheat scientists gathered to learn about new approaches and methods for wheat improvement in Faisalabad, Pakistan. CIMMYT and the Wheat Research Institute, Faisalabad (WRI-FSD) jointly organized a two-day training. The course covered two topics: high throughput genotyping technologies and high throughput phenotyping platforms. The trainees, who were able to attend in person or remotely and 27% of whom were women, hailed from 17 NARES partners across Pakistan.
After being welcomed by the Director General of Ayub Agricultural Research Institute (AARI), Akhtar Ali, and CIMMYT’s Country Representative, TP Tiwari, participants received an update on the status of wheat in Pakistan from Muhammad Sohail, national wheat coordinator for the Pakistan Agricultural Research Council (PARC). Subsequently, WRI-FSD Director, Javed Ahmed, discussed wheat research in Punjab, where over 70% wheat is grown in Pakistan. Kevin Pixley, interim director of CIMMYT’s Global Wheat Program, joined the proceedings remotely for a conversation about CIMMYT’s and CGIAR’s collaboration with NARES. Participants discussed the model’s successes, bottlenecks, the role of NARES, and the potential for capacity development. The conversation generated broad interest and suggestions for enhancing the partnership’s effectiveness. Akhtar Ali, Muhammad Sohail, and Javed Ahmed all spoke very highly about CIMMYT’s support in Pakistan.
This event was organized as part of a collaborative project entitled “Rapid development of climate resilient wheat varieties for South Asia using genomic selection” that is jointly managed by Kansas State University and CIMMYT with funding from the USAID Feed the Future program.
“Training emphasized the need for an output-oriented researcher that covered the development of climate-resilient wheat varieties, given the environmental challenges we are experiencing like, drought and heat, and highlighted the importance of innovative methodologies and advanced tools for high throughput phenotyping and genotyping for sustainable and resilient wheat production in Pakistan” said Muhammad Ishaq, a senior research officer and one of the training participants from Kohat Research Station, Khyber Pakhtunkhwa.
At the conclusion of the training, Javed, direct of WRI Faisalabad, commended CIMMYT’s support and suggested continuing the pace of training. Dr. Tiwari stressed the importance of such efforts will help Pakistan’s scientists develop and deploy climate resilient, impactful wheat varieties to boost wheat production and reduce wheat imports in the country.

One of the world’s largest crop pathogen surveillance systems is set to expand its analytic and knowledge systems capacity to protect wheat productivity in food vulnerable areas of East Africa and South Asia.
Researchers announced the Wheat Disease Early Warning Advisory System (Wheat DEWAS), funded through a $7.3 million grant from the Bill & Melinda Gates Foundation and the United Kingdom’s Foreign, Commonwealth & Development Office, to enhance crop resilience to wheat diseases.
The project is led by David Hodson, principal scientist at CIMMYT, and Maricelis Acevedo, research professor of global development and plant pathology at Cornell University’s College of Agriculture and Life Sciences. This initiative brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.
Wheat DEWAS aims to be an open and scalable system capable of tracking important pathogen strains. The system builds on existing capabilities developed by the research team to provide near-real-time model-based risk forecasts and resulting in accurate, timely and actionable advice to farmers. As plant pathogens continue to evolve and threaten global food production, the system strengthens the capacity of countries to respond in a proactive manner to transboundary wheat diseases.
The system focuses on the two major fungal pathogens of wheat known as rust and blast diseases. Rust diseases, named for a rust-like appearance on infected plants, are hyper-variable and can significantly reduce crop yields when they attack. The fungus releases trillions of spores that can ride wind currents across national borders and continents and spread devastating epidemics quickly over vast areas.
Wheat blast, caused by the fungus Magnaporte oryzae Tritici, is an increasing threat to wheat production, following detection in both Bangladesh and Zambia. The fungus spreads over short distances and through the planting of infected seeds. Grains of infected plants shrivel within a week of first symptoms, providing little time for farmers to take preventative actions. Most wheat grown in the world has limited resistance to wheat blast.
“New wheat pathogen variants are constantly evolving and are spreading rapidly on a global scale,” said Hodson, principal investigator for Wheat DEWAS. “Complete crop losses in some of the most food vulnerable areas of the world are possible under favorable epidemiological conditions. Vigilance coupled with pathogen-informed breeding strategies are essential to prevent wheat disease epidemics. Improved monitoring, early warning and advisory approaches are an important component for safeguarding food supplies.”
Previous long-term investments in rust pathogen surveillance, modelling, and diagnostics built one of the largest operational global surveillance and monitoring system for any crop disease. The research permitted the development of functioning prototypes of advanced early warning advisory systems (EWAS) in East Africa and South Asia. Wheat DEWAS seeks to improve on that foundation to build a scalable, integrated, and sustainable solution that can provide improved advanced timely warning of vulnerability to emerging and migrating wheat diseases.
“The impact of these diseases is greatest on small-scale producers, negatively affecting livelihoods, income, and food security,” Acevedo said. “Ultimately, with this project we aim to maximize opportunities for smallholder farmers to benefit from hyper-local analytic and knowledge systems to protect wheat productivity.”
The system has already proven successful, contributing to prevention of a potential rust outbreak in Ethiopia in 2021. At that time, the early warning and global monitoring detected a new yellow rust strain with high epidemic potential. Risk mapping and real-time early forecasting identified the risk and allowed a timely and effective response by farmers and officials. That growing season ended up being a production record-breaker for Ethiopian wheat farmers.
While wheat is the major focus of the system, pathogens with similar biology and dispersal modes exist for all major crops. Discoveries made in the wheat system could provide essential infrastructure, methods for data collection and analysis to aid interventions that will be relevant to other crops.
CIMMYT targets some of the world’s most pressing problems: ending poverty, ensuring food for the future, mitigating climate change and improving the lives of farmers and consumers (especially women). CIMMYT is a CGIAR Research Center and has long been the world’s leading center for research on maize and wheat. This research capacity is being harnessed to achieve the crucial goals of climate resilience, and food and nutrition security.
Most of the world’s people depend on annual grain crops for their survival. Yet some of the world’s poorest men and women produce cereals. Annual grain farming has exacerbated climate change. The world’s great challenges of achieving climate resilience and nutrition security are being addressed by focusing CIMMYT’s research and development (R&D) on maize, and wheat, as well as on underutilized grain and legume crops.
Highlights from the 2022 Annual Report:
Annual cereal farming tends to release carbon into the atmosphere, while degrading the soil. Improving the soil takes years, and the high annual variation in weather demands long-term experiments. Field trials by CIMMYT over many years show that farmers can return carbon to the soil by using minimum tillage, rotating cereals with legumes, and by applying animal manure and strategic amounts of nitrogen fertilizer. As soil fertility improves, so do farmers’ yields.
Eleven million farmers in India alone produce maize, usually without irrigation, exposing families to climate-related disaster. Twenty new hybrids bred by CIMMYT out-perform commercial maize, even in drought years. One thousand tons of this heat-tolerant maize seed have now been distributed to farmers across South Asia.
Some wheat is rich in zinc and iron, which prevent anemia, especially in children. Yet naturally-occurring phytic acid in wheat blocks the body’s absorption of these minerals. A technique developed by CIMMYT lowers the cost of assaying phytic acid, so plant breeders in developing countries can identify promising lines of wheat faster. CIMMYT is also helping to reduce food imports by learning how other crops, like cassava and sorghum, can be blended with wheat to make flours that consumers will accept.
Some wheat hotspots are warm, dry, and subject to plant diseases. CIMMYT collaborates with plant breeders worldwide through the International Wheat Improvement Network (IWIN) to test promising new wheat lines in these tough environments. As more places become warmer and drier with climate change, CIMMYT and allies are developing wheat varieties that will thrive there.
Harvesting more maize in the future will depend on higher yields, not on planting more land. In plant breeding programs in Africa, South Asia and Latin America, CIMMYT and partners are already developing maize varieties and hybrids that will be released in just a few years. A review of these efforts reveals that annual yield increases will be about twice the rate achieved from 1973 to 2012.
Sorghum, millets, pigeon pea, chickpea and groundnuts have been favorite food crops in Africa for centuries. They are already adapted to warm, dry climates. CIMMYT is now working with national research programs to ensure that new crop varieties have the traits that male and female farmers need. Seed systems are being organized to produce more of Africa’s preferred crops.
Researchers can only breed new crop varieties if someone saves the old ones from extinction. CIMMYT does that with its world-class collection of wheat and maize seed. In 2022, CIMMYT’s two separate wheat and maize germplasm banks were combined into one. Modern techniques, such as vacuum-sealed seed packets and QR codes, allow rapid response to requests for seed from plant breeders around the world.
CIMMYT is helping Nepali farmers to plant maize in the lowlands, in the spring, when most land lies fallow. In 2022, CIMMYT provided training and investment to 2,260 farmers (35% women), who earned, on average, an additional $367 in one year. The added income allowed these farmers to invest in health care and schooling for their children.
Mexican farmers are saving money, harvesting more and selling their grain more easily. Some 4,000 farmers are now selling on contract to food manufacturing companies. The farmers lower production costs by using CIMMYT innovations in irrigation, fertilizer application and ecological pest control. Yields increase, the soil improves, and farmers find a ready market for their harvest.
The stories we have highlighted in this article are just some of the ones included in the Annual Report. See the full text of all the stories in “Harvesting Success” to learn how CIMMYT scientists are doing some of the most important research, for some of the world’s best causes.
India can applaud a hallmark in national food production: in 2023, the harvest of wheat—India’s second most important food crop—will surpass 110 million tons for the first time.
This maintains India as the world’s number-two wheat producer after China, as has been the case since the early 2000s. It also extends the wheat productivity jumpstart that begun in the Green Revolution—the modernization of India’s agriculture during the 1960s-70s that allowed the country to put behind it the recurrent grain shortages and extreme hunger of preceding decades.
“Newer and superior wheat varieties in India continually provide higher yields and genetic resistance to the rusts and other deadly diseases,” said Distinguished Scientist Emeritus at CIMMYT, Ravi Singh. “More than 90 percent of spring bread wheat varieties released in South Asia in the last three decades carry CIMMYT breeding contributions for those or other valued traits, selected directly from the Center’s international yield trials and nurseries or developed locally using CIMMYT parents.”
Wheat grain yield in Indian farmers’ fields rose yearly by more than 1.8 percent—some 54 kilograms per hectare—in the last decade, a remarkable achievement and significantly above the global average of 1.3 percent. New and better wheat varieties also reach farmers much sooner, due to better policies and strategies that speed seed multiplication, along with greater involvement of private seed producers.
“The emergence of Ug99 stem rust disease from eastern Africa in the early 2000s and its ability to overcome the genetic resistance of older varieties drove major global and national initiatives to quickly spread the seed of newer, resistant wheat and to encourage farmers to grow it,” Singh explained. “This both protected their crops and delivered breeding gains for yield and climate resilience.”
CIMMYT has recently adopted an accelerated breeding approach that has reduced the breeding cycle to three years and is expected to fast-track genetic gains in breeding populations and hasten delivery of improvements to farmers. The scheme builds on strong field selection and testing in Mexico, integrates genomic selection, and features expanded yield assays with partner institutions. To stimulate adoption of newer varieties, the Indian Institute of Wheat and Barley Research (IIWBR, of the Indian Council of Agricultural Research, ICAR) operates a seed portal that offers farmers advanced booking for seed of recently released and other wheat varieties.
Private providers constitute another key seed source. In particular, small-scale seed producers linked to the IIWBR/ICAR network have found a profitable business in multiplying and marketing new wheat seed, thus supporting the replacement of older, less productive or disease susceptible varieties.
Farm innovations for changing climates and resource scarcities
Following findings from longstanding CIMMYT and national studies, more Indian wheat farmers are sowing their crops weeks earlier so that the plants mature before the extreme high temperatures that precede the monsoon season, thus ensuring better yields.
New varieties DBW187, DBW303, DBW327, DBW332 and WH1270 can be planted as early as the last half of October, in the northwestern plain zone. Recent research by Indian and CIMMYT scientists has identified well-adapted wheat lines for use in breeding additional varieties for early sowing.
Resource-conserving practices promoted by CIMMYT and partners, such as planting wheat seed directly into the unplowed fields and residues from a preceding rice crop, shave off as much as two weeks of laborious plowing and planking.
“This ‘zero tillage’ and other forms of reduced tillage, as well as straw management systems, save the time, labor, irrigation water and fuel needed to plant wheat, which in traditional plowing and sowing requires many tractor passes,” said Arun Joshi, CIMMYT wheat breeder and regional representative for Asia and managing director of the Borlaug Institute for South Asia (BISA). “Also, letting rice residues decompose on the surface, rather than burning them, enriches the soil and reduces seasonal air pollution that harms human health in farm communities and cities such as New Delhi.”
Sustainable practices include precision levelling of farmland for more efficient irrigation and the precise use of nitrogen fertilizer to save money and the environment.
Science and policies ensure future wheat harvests and better nutrition
Joshi mentioned that increased use of combines has sped up wheat harvesting and cut post-harvest grain losses from untimely rains caused by climate change. “Added to this, policies such as guaranteed purchase prices for grain and subsidies for fertilizers have boosted productivity, and recent high market prices for wheat are convincing farmers to invest in their operations and adopt improved practices.”
To safeguard India’s wheat crops from the fearsome disease wheat blast, native to the Americas but which struck Bangladesh’s wheat fields in 2016, CIMMYT and partners from Bangladesh and Bolivia have quickly identified and cross-bred resistance genes into wheat and launched wheat disease monitoring and early warning systems in South Asia.
“More than a dozen wheat blast resistant varieties have been deployed in eastern India to block the disease’s entry and farmers in areas adjoining Bangladesh have temporarily stopped growing wheat,” said Pawan Singh, head of wheat pathology at CIMMYT.
Building on wheat’s use in many Indian foods, under the HarvestPlus program CIMMYT and Indian researchers applied cross-breeding and specialized selection to develop improved wheats featuring grain with enhanced levels of zinc, a micronutrient whose lack in Indian diets can stunt the growth of young children and make them more vulnerable to diarrhea and pneumonia.
“At least 10 such ‘biofortified’ wheat varieties have been released and are grown on over 2 million hectares in India,” said Velu Govindan, CIMMYT breeder who leads the Center’s wheat biofortification research. “It is now standard practice to label all new varieties for biofortified traits to raise awareness and adoption, and CIMMYT has included high grain zinc content among its primary breeding objectives, so we expect that nearly all wheat lines distributed by CIMMYT in the next 5-8 years will have this trait.”
A rigorous study published in 2018 showed that, when vulnerable young children in India ate foods prepared with such zinc-biofortified wheat, they experienced significantly fewer days of pneumonia and vomiting than would normally be the case.
Celebrating joint achievements and committing for continued success
The April-June 2018 edition of the “ICAR Reporter” newsletter called the five-decade ICAR-CIMMYT partnership in agricultural research “…one of the longest and most productive in the world…” and mentioned mutually beneficial research in the development and delivery of stress resilient and nutritionally enriched wheat, impact-oriented sustainable and climate-smart farming practices, socioeconomic analyses, and policy recommendations.
Speaking during an August 2022 visit to India by CIMMYT Director General Bram Govaerts, Himanshu Pathak, secretary of the Department of Agricultural Research and Education (DARE) of India’s Ministry of Agriculture and Farmers Welfare and Director General of ICAR, “reaffirmed the commitment to closely work with CIMMYT and BISA to address the current challenges in the field of agricultural research, education and extension in the country.”
“The ICAR-CIMMYT collaboration is revolutionizing wheat research and technology deployment for global food security,” said Gyanendra Singh, director, ICAR-IIWBR. “This in turn advances global peace and prosperity.”
According to Govaerts, CIMMYT has concentrated on strategies that foster collaboration to deliver greater value for the communities both ICAR and the Center serve. “The way forward to the next milestone — say, harvesting 125 million tons of wheat from the same or less land area — is through our jointly developing and making available new, cost effective, sustainable technologies for smallholder farmers,” he said.
Wheat research and development results to date, challenges, and future initiatives occupied the table at the 28th All India Wheat & Barley Research Workers’ Meeting, which took place in Udaipur, state of Rajasthan, August 28-30, 2023, and which ICAR and CIMMYT wheat scientists attended.
Generous funding from various agencies, including the following, have supported the work described: The Australian Centre for International Agricultural Research (ACIAR), the Bill & Melinda Gates Foundation, the Federal Ministry for Economic Cooperation and Development of Germany (BMZ), the Foreign, Commonwealth & Development Office of UK’s Government (FCDO), the Foundation for Food & Agricultural Research (FFAR), HarvestPlus, ICAR, the United States Agency for International Development (USAID), funders of the One CGIAR Accelerated Breeding Initiative (ABI), and the Plant Health Initiative (PHI).
Intention, collaboration and commitment are critical to bridging the research and practice gap. Gender development practitioners and researchers from CGIAR centers, universities, national agricultural research and extension systems (NARES), civil society, and donor representatives this week shared insights from their research and work at the gender conference in New Delhi, India.
The discussion and exchange promises to create collaborations and opportunities devoted to improving the conditions and agency of women, youth and Indigenous communities in the Global South. “Transformative research can lead to meaningful impact,” said Angela Meentzen, senior gender researcher at CIMMYT. “We have been looking forward to this conference because coming together as researchers, scientists and development practitioners, we can discuss and share insights from each other’s practices and experiences from the field.”
Leading researchers and scientists from CIMMYT Asia and Africa presented their research and enriched the gender discussions at the conference. Meentzen said that CIMMYT is proud to support gender research that contributes meaningfully to transformative change and impact.
Below are highlights of four research poster presentations by our researchers (of the six presented by CIMMYT) at the conference:
Scientist Vijayalaxmi Khed examined how women manage excess workload (working inside and outside the house), a clear trade-off between productive and leisure time without change in domestic responsibilities. Due to domestic workload, she found that women’s time away from farms does not translate into leisure. Another important finding was that women with more agency had less time for leisure, unlike for men.
In her poster presentation, she concluded that rural women’s nexus of time poverty and decision-making has “clear implications for the development and diffusion of laborsaving technologies in agriculture.”
Working on the same study with Khed, Vijesh Krishna explored the relationship between women’s involvement in agricultural activities and decision-making. His presentation, ‘Farm managers or unpaid laborers?’, from the study covering 347 wheat-farming households across two years, concludes that “despite playing a crucial role in wheat farming in central India, most women lacked the ability to influence decisions.”
Gender-intentional maize breeding for better adoption and productivity in sub-Saharan Africa
Michael Euler, agriculture and resource economist, in his poster presentation explained how an on-farm trial to improve gender-intentional breeding and varietal adoption in maize was designed by CIMMYT breeders and researchers.
The study hypothesized that gender dynamics in household labor allocation and decision-making in maize systems influence trait preferences and farmers’ adoption of varieties. So, researchers conducted on-farm trials and household surveys with individual women and men household members to capture differences in their trait preferences in maize cultivation—production systems, seed demand and seed access—with 800 smallholder farmers in Zimbabwe and Kenya.
Euler emphasized the influence of socioeconomic and agroecological factors, including biotic–abiotic stress, in the household decisions on maize varietal adoption.
He concluded that the study results will help “guide the product development of regional maize breeding programs and strengthen communities’ adaptation to the changing environmental conditions for maize cultivation.”
Adoption of a weeding technology may lead to labor displacement of marginalized women laborers
Presenting a poster for the same session as Euler, Maxwell Mkondiwa—in a study coauthored with colleagues Khed and Krishna—highlighted how rapid diffusion of a laborsaving technology like herbicides could exclude the marginalized further. The study occurred in India’s state of Bihar, looking at nonfarming rural poor, primarily women, from socially marginalized groups.
From data on chemical weeding, the study analyzed the technology’s impact on inequality— highlighting how marginalized women laborers who work on manual weeding are then replaced by men who apply herbicides.
He stressed that not enough research is devoted to understanding whether farmer adoption of laborsaving technologies worsens economic inequalities or reinstates labor into better tasks. “We hope the evidence we generated will help researchers and policymakers develop relevant actions toward more inclusive innovations, and support laborers with new skills for the transitions,” said Mkondiwa.
Women exhibit limited technical knowledge and experience social benefits differently in male-headed households of CASI technology adoption
Emma Karki, in her poster, explained that there is limited knowledge of the impact of technology adoption on women in a male-headed household in South Asia—with decision powers generally resting with male household members. The research tried to understand the gendered differences in the evaluation of technology adoption in male-headed households using conservation agriculture-based sustainable intensification (CASI) technology as a case study.
The study focused on identifying the commonalities and differences in the experiences and evaluation of CASI technology. Results indicated that “despite technology adoption, women had limited mechanistic understanding compared to men, with similar limitations on women’s time use and capacity development,” said Karki.
For future CASI promotion, Karki concluded: “Reducing information gaps and incorporating technological preferences of women needs prioritizing, including creating opportunities for them to access knowledge and engage both men and women in critical discussions surrounding gender norms.”
Similarly, Moti Jaleta’s research presentation highlighted the challenges of mechanization adoption for smallholder farmers in Ethiopia, primarily women. “Intentional research, whether in gender or social development, helps identify problems and opportunities for change,” endorsed Jaleta.
Meaningful research helps achieve gender and social inclusion goals
The ‘From Research to Impact: CGIAR GENDER Impact Platform and ICAR Conference 2023’, between October 9-12, 2023, in New Delhi, gathered researchers from 68 countries. In her inaugural address at the conference’s opening, the President of India Smt. Draupadi Murmu affirmed, “For ecologically sustainable, ethically desirable, economically affordable and socially justifiable production, we need research which can enable conditions to reach these goals.”
At the end of the four-day conference—with 60 research presentations and six plenary sessions—the organizers and participants reflected on their resolve ‘From Research To Impact,’ and the promise to recognize and collectively address the gender and social inequities in agrifood systems development.
Bhumi Shara Khadka is a 35-year-old community business facilitator who has made significant strides in agriculture and community development. Her journey began after completing training in sales skill development and technical capacity building for community business facilitators (CBF) organized by the Cereal Systems Initiative for South Asia (CSISA) in June 2022 and April 2023, respectively. This training opened up new opportunities, and she soon secured a job as a CBF. However, her ambitions didn’t stop there.
In February 2022, the Cereal Systems Initiative for South Asia (CSISA) recognized her potential and recommended her for a role as a community business facilitator with Laxmi Agrovet, a local agribusiness. To prepare for her new position, Ms. Khadka underwent additional training in various areas, including running sales meetings, farm mechanization, post-harvest handling and the fundamentals of sales and marketing. With these tools in hand, she set out to make a difference in the lives of farmers and the broader community.
To date, Khadka has conducted 97 sales meetings with farmer groups where she explains improved production methods, plant protection, post-harvest handling and how to market agriculture products effectively. She also demonstrates and sells Laxmi Agrovet agri-inputs such as seeds, fertilizer and tools. She gets a 20% commission on sales, bringing her an average net monthly income of NPR3,375 (US$26). Her role as community business facilitator also involves linking farmers with the local government agriculture program. As a result of her efforts, three farmers have each acquired a mini power tiller at a 50% subsidy.
Inspired by Khadka’s example, Chitra Bahadur Rokaya, acting director of the Agricultural Regional Directorate in Surkhet, Nepal, has expressed his desire to visit farmers and learn more about the activities of community business facilitators like Khadka during the technical capacity-building training to CBF in April 2023. Rokaya has expressed gratitude to trainees who attended the IPM training organized by CSISA and would visit the field sites of the trainees, if possible.
Khadka has also used her knowledge as a business facilitator and IPM trainee to establish her commercial vegetable farm, which, with her investment and CSISA’s technical support, now occupies five ropani (0.01 hectares). Her husband helps out and Bhumi sells the produce at local markets in Melkuna and Badichour, Surkhet, with traders often coming to the farm to buy from her directly. Last year, she earned NPR227,000 (US$1,733) of which her net income was NPR63,500 (US$485). Since starting the farm, the family’s food habits and those of her neighbors have changed for the better. Last year, the family kept a quarter of the vegetables she produced for their consumption, and she gave about 10% to neighbors.
Last year, under Khadka’s facilitation, 48 farmers cultivated vegetables on an average of 0.02 hectares each, each achieving an average net profit of NPR63,500 (US$485). Khadka also owns a power tiller, which she rents out for others to use, earning NPR35,000 (US$267) last year from this service provision activity.
In addition to her business and professional success, Khadka completed high school in 2014, underlining the significance of her accomplishments. Khadka’s remarkable journey is an inspiring agriculture success story, showcasing the transformative power of women empowerment in rural communities. Her dedication, knowledge and entrepreneurial spirit have improved farmers’ lives and elevated the entire community’s access to nutritious food. Her unwavering commitment to her work has brought her well-deserved recognition, and she is a beacon of hope for others in similar fields of endeavor.
On October 4, 2023, Sieglinde Snapp, program director of the Sustainable Agrifood System (SAS) program, along with the country representative of CIMMYT and project lead of the Nepal Seed and Fertilizer Project (NSAF) Dyutiman Choudhary, visited the National Soil Science Research Center (NSSRC) under the Nepal Agricultural Research Council (NARC). The chief of NSSRC, Shree Prasad Vista, and his team welcomed Snapp and the team from CIMMYT. In the meeting, Vista presented an overview of NSSRC’s work and emphasized the collaborative work with NSAF. He focused on the achievements NSSRC has accomplished with the joint efforts of NSAF. He highlighted the launch of the Digital Soil Map and new fertilizer recommendations. He also reflected on the benefits of soil health cards to the farmers that NSAF supported. In addition, he prioritized the importance of collaboration to improve the livelihood of farmers. He appreciated the cross-learning that CIMMYT has been providing for knowledge transfer and adopting best management practices. After the meeting, the team visited the NSSRC’s laboratory, which provided insights about their soil research activities.
Following the visit to NSSRC, Snapp and CIMMYT colleagues visited the NARC Head Office within the same premises. The Executive Director of NARC, Dhurbaraj Bhattari, welcomed the delegates in his office. The ED presented an overview of NARC and its primary focus. He emphasized the importance of collaborative work with CIMMYT. After the presentation, the delegates from CIMMYT, NARC and NSSRC discussed critical issues regarding sustainable agricultural practices. The primary focus of the meeting was the strategies to boost sustainable agricultural productivity to enhance crop yields, value chain enhancement for farmer’s benefits, policy development for collaboration and harmonization to encourage horizontal and vertical cooperation between different stakeholders, need for investment in research and infrastructure at the grassroots level for addressing the challenges faced by farmers.
Addressing the meeting, Snapp focused on the importance of partnership aligning with CIMMYT’s latest strategies to facilitate knowledge transfer and the adoption of best practices. She also raised her concerns regarding the loss of crops between harvest and storage. She reflected on the commitment of CIMMYT to improving agriculture through science and innovation to change the livelihood of farmers. She showed her commitment to ongoing collaboration for sustainable agricultural development.
The meeting provided a platform to strengthen the longstanding collaboration between CIMMYT and NARC to address the challenges faced by farmers to enhance agricultural productivity through sustainable approaches. The Executive Director of NARC extended heartfelt gratitude for CIMMYT’s support, which has played a pivotal role in transforming the lives of countless farmers. He also expressed hope for continued collaboration in the future.
Snapp visited CIMMYT Nepal from October 3-7, 2023. 2023. During her visit, she interacted and engaged with various stakeholders, including Nepal staff, farmers in the field, agricultural cooperatives, government authorities, seed growers, suppliers and feed mills.
In Nepal, the International Water Management Institute and CIMMYT conducted research on Sustainable Intensification of Mixed Farming System (SI-MFS) in collaboration with local governments in Gurbakot Municipality of Surkhet and Haleshi Tuwachung Municipality of Khotang.
The research found a noticeable shift in farmers’ interest in farming practices, where successful implementation of innovation and scaling, it’s crucial to have farmers’ interest and ownership in interventions.

Are agroecological approaches, based for example on the use of legumes and manure, enough by themselves to ensure a long-term increase in annual crop yields in sub-Saharan Africa (SSA), without using more mineral fertilizer?
The answer is no, according to a team of agronomists who have published an in-depth analysis of 150 scientific articles on annual crops (maize, sorghum, millet, rice, cassava, etc.) and tropical legumes, both annual grain legumes (cowpea, groundnut) and legume trees (acacia, sesbania) in tropical environments.
These publications collate 50 years of knowledge on nutrient balances in sub-Saharan Africa, biological nitrogen fixation by tropical legumes, manure use in smallholder farming systems and the environmental impact of mineral fertilizer.
“When we look at comparable climate conditions and physical soil constraints, yields of maize – the main source of calories for people – in sub-Saharan Africa are three to four times lower than elsewhere in the world. This is largely due to the fact that mineral fertilizer use (nitrogen, potassium) is on average four times lower there”, says Gatien Falconnier, a researcher at CIRAD based in Zimbabwe and lead author of the article. “On average, 13 kg of nitrogen are used per hectare and per year in sub-Saharan Africa, for all crops, bearing in mind that the poorest farmers have no access to nitrogen fertilizers and therefore do not use them. It is mainly agri-business and vegetable farmers that have access to fertilizers”, adds François Affholder, an agronomist at CIRAD based in Mozambique and co-author of the article.
“Our objective is not to produce like Europe or North America, but to produce more and more regularly according to the seasons and the years, and thus to increase the economic sustainability of our farming systems. To do so, we must ensure a minimum level of nutrients for crops, which require essential mineral elements for efficient photosynthesis, and therefore growth. Soils are typically lacking in mineral elements in sub-Saharan Africa, and the largely insufficient organic inputs lead to nutrient deficiencies in crops. This is the main limiting factor for crop yields, excluding drought situations”, says Pauline Chivenge of the African Plant Nutrition Institute (APNI). “The work by Christian Pieri showed as early as 1989 that it is possible to restore high levels of fertility to African soils through a balanced approach to organic and mineral nutrient inputs”, says François Affholder.
The article highlights five reasons why more mineral fertilizer is needed in sub-Saharan Africa:
“If we take account of biophysical production factors, such as climate and soil, and shortages of land and agricultural workers, it will be impossible to reach a satisfactory production level by fertilizing soils only with manure and using legumes”, says Leonard Rusinamhodzi, an agricultural researcher at the Ghana International Institute of Tropical Agriculture.
However, “agroecological principles linked directly to improving soil fertility, such as recycling of mineral and organic elements, crop efficiency and diversity, with for example agroforestry practices and cereal-legume intercropping, remain essential to improve soil health. Soil fertility is based on its organic matter content, provided by plant growth that determines the biomass that is returned to the soil in the form of roots and plant residues. Efficient mineral fertilizer use starts a virtuous circle. These nutrients are crucial for the sustainability of agricultural productivity”, says Gatien Falconnier.
The researchers therefore argue for a nuanced position that recognizes the need to increase mineral fertilizer use in sub-Saharan Africa, in a moderate manner based on efficient practices, in conjunction with the use of agroecological practices and appropriate policy support. This balanced approach is aimed at ensuring long-term food security while preserving ecosystems and preventing soil degradation.

Paraguay’s Minister of Foreign Affairs, Ambassador Julio César Arriola, recently bestowed on Man Mohan Kohli, retired wheat geneticist of CIMMYT the “Comendador” award of the country’s National Order of Merit, highlighting the scientist’s “…exceptional contribution to Paraguayan agriculture and economy.”
A native of India, where he completed schooling including a Ph.D. in wheat genetics, Kohli worked at CIMMYT during 1971-2004 on topics including spring x winter wheat crosses, resistance in wheat to the rust and other diseases, and the improvement and promotion of triticale, a wheat x rye hybrid.
In 1978 he was assigned to a CIMMYT regional program involving wheat breeding, development and training in collaboration with countries of the Southern Cone of South America, which included facilitating the regional testing and exchange of wheat breeding lines and selection data.
As of 2004, Kohli has been an active part-time consultant with Paraguay’s national wheat program and the Bioceres Group in Argentina.
“Funding ended for CIMMYT wheat research in Paraguay in 1993,” Kohli said. “In 2003 we started direct cooperation again through a joint venture including the Ministry of Agriculture and Livestock, the Paraguayan Chamber of Cereals and Oilseeds Exporters, and CIMMYT.”
“Back in 2003, Paraguay was producing about 320,000 tons of wheat each year and importing over 200,000 tons. Now, yearly output is around 1 million tons and the country exports almost a third of that.”
Kohli said the joint initiative had promoted higher-yielding wheat varieties and farming methods, lowered the costs of agrochemicals, and helped form associations involving farmers and millers—the complete cycle from sowing to marketing for wheat.
Paraguayans eat an average of over 85 kilograms of wheat each year as pasta, bread and other bakery products.
Kohli’s career has led him to work with science luminaries such as M.S. Swaminathan, Glenn Anderson, Joe Rupert, Cal Qualset, Warren Kronstad, Frank Zillinsky, and Sanjaya Rajaram, among others.
“I met CIMMYT scientist and eventual Nobel Peace laureate, Dr. Norman E. Borlaug, in 1967,” Kohli said. “We continued to meet every year on his visits to India and, when I was about to finish my Ph.D. in 1970, he invited me to join the team at CIMMYT.”
“It has been a privilege and honor to have worked alongside many dedicated colleagues at CIMMYT and national programs who have contributed significantly to building research capacities and global food security over the last 50 years. This award is dedicated to all of them and the farmers who have been the primary source of inspiration for our work”.

A recent webinar organized by CIMMYT brought together three experts to discuss the importance of millets as key contributors to improving food and nutrition security and resilience to climate change. Offering a wealth of knowledge and insights, the panel discussion was moderated by Kevin Pixley, director of the Dryland Crops Program (DCP), who led a dynamic and engaging discussion highlighting CIMMYT’s work on dryland crops, the climate resiliency and versatility of millets, and biofortification initiatives.
“Millet improvement programs are central to regional dryland crop improvement networks”, stated Harish Gandhi, breeding lead for DCP. Providing a comprehensive overview of the program, Gandhi emphasized its significance in addressing food and nutrition security as well as climate resilience. “With partners, we are co-designing and co-implementing crop improvement strategies, catalyzing the development of effective and sustainable crop improvement networks”, he said. The dryland crop improvement networks bring together 17 National Agricultural Research and Extension Systems (NARES) in Western, Central, Eastern and Southern Africa working jointly to cultivate the potential and impacts of sorghum, pearl millet, groundnut, cowpea, bean, pigeon pea and chickpea. The program is aligned with CGIAR and the CIMMYT 2030 Strategy to transform agrifood systems through a dense network of impactful partnerships for enhanced sustainability, productivity and profitability.
The climate resiliency and adaptability of millets to arid and semi-arid regions make them a staple for smallholder farmers in Africa. “Millet is a drought-tolerant, climate-resilient crop with profound nutritional benefits. It’s rich in iron, zinc and other essential nutrients, making it a promising food against malnutrition and diet-related diseases”, emphasized Maryam Dawud, project lead at the Lake Chad Research Institute in Nigeria. Highlighting the significance of millets in building resilient agricultural systems, Dawud also explored innovations in millet consumption in diverse food products, including gluten-free options.
Mahalingam Govindaraj, senior scientist at HarvestPlus-Alliance Bioversity and CIAT, gave insights into crop biofortification, underlining the pressing need for crop nutritional enhancement due to widespread deficiencies, especially in the Global South. He introduced the HarvestPlus developed Biofortification Priority Index (BPI) which enables decision makers to make informed decisions about crop selection, target nutrients and countries. Additionally, Govindaraj highlighted the success of biofortification in enhancing essential micronutrients, especially in pearl millet, and discussed the science, technology and innovations that help to drive the mainstreaming of biofortification within CGIAR and NARES breeding and testing programs.
During the Q&A session, the speakers addressed questions from the audience of more than 150 participants, clarifying misconceptions and expanding on their subjects. Questions from the engaging audience span a wide range of themes and included the significance of different millet types and why they are frequently grouped together; the correlation between zinc and iron content in pearl millets, particularly in relation to their high fiber content; and the strategic approach of dryland crops in supporting capacity building for the NARES, among many other topics.
As the webinar came to a close, it was evident that millets are more than just cereals; they offer a promising solution to a variety of global food system challenges. From their resilience in harsh climates to their rich nutritional value and potential for innovation in various food products, millets stand as a beacon of hope in developing climate-resilient agriculture for a sustainable future.
The webinar is also accessible in Spanish, French and Hindi.
Climate change poses a significant challenge to agricultural production and food security worldwide. “Rising temperatures, shifting weather patterns and more frequent extreme events have already demonstrated their effects on local, regional and global agricultural systems”, says Kevin Pixley, Dryland Crops Program director and Wheat Program director a.i. at CIMMYT. “As such, crop varieties that can withstand climate-related stresses and are suitable for cultivation in innovative cropping systems will be crucial to maximizing risk avoidance, productivity and profitability under climate-changed environments.”
In a new study published in Molecular Plant, scientists from CIMMYT, Alliance of Bioversity International and CIAT, the International Institute of Tropical Agriculture (IITA) and national agricultural research programs in Burkina Faso, Ethiopia, Nigeria, Tanzania and Uganda to predict novel traits that might be essential for future varieties of popular crops. Having surveyed nearly 600 agricultural scientists and stakeholders, they identify likely agronomic changes in future cropping systems seeking sustainability, intensification, resilience and productivity under climate change, as well as associated essential and desirable traits, especially those that are not currently prioritized in crop improvement programs.
Focusing on six crops which hold vital importance for African food security and CIMMYT and CGIAR’s mission—maize, sorghum, pearl millet, groundnut, cowpea and common bean—the authors review opportunities for improving future prioritized traits, as well as those they consider ‘blind spots’ among the experts surveyed.
Predicting future essential traits
The results of the study speak to the need for considering cropping systems as central to climate change resilience strategy, as well as the need to reconsider the crop variety traits that will eventually become essential.
Overall, experts who participated in the survey prioritized several future-essential traits that are not already targeted in current breeding programs — mainly water use efficiency in pearl millet, groundnut, and cowpea; adaptation to cropping systems for pearl millet and maize; and suitability for mechanization in groundnut. The survey confirmed that many traits that are already prioritized in current breeding programs will remain essential, which is unsurprising and consistent with other recent findings. While smarter and faster breeding for currently important traits is essential, the authors suggest that failure to anticipate and breed for changing needs and opportunities for novel characteristics in future varieties would be a big mistake, compromising farmers’ resilience, improved livelihood opportunities, and food security in the face of changing climate.
Importantly, the authors explain, the predicted future-essential traits include innovative breeding targets that must be prioritized. They point to examples such as improved performance in inter- or relay-crop systems, lower nighttime respiration, improved stover quality, or optimized rhizosphere microbiome, which has benefits for nitrogen, phosphorous and water use efficiency.
The authors emphasize that the greatest challenge to developing crop varieties to win the race between climate change and food security might be innovativeness in defining and boldness to breed for the traits of tomorrow. With this in mind, they outline some of the cutting-edge tools and approaches that can be used to discover, validate and incorporate novel genetic diversity from exotic germplasm into breeding populations with unprecedented precision and speed.
