To address challenges caused by maize diseases and pests, AATF renews its commitment to the TELA maize project, which works towards the commercialization of transgenic drought-tolerant and insect-proof maize varieties to safeguard food security in Sub-Saharan Africa.
The Livestock Production Systems in Zimbabwe (LIPS-ZIM) project promotes climate-relevant innovation to better manage livestock disease and production systems.
Agrovita, which launched in 2021, aims to boost the productivity of 900 farmers over three years through actions that improve their communities’ food security by implementing regenerative farming practices across almost 30,000 acres. The program also aims to ensure that 50% of its beneficiaries are women.
Through decades-long Asian and global partnerships, the International Maize and Wheat Improvement Center (CIMMYT) is refining and spreading a suite of resource-conserving, climate-smart innovations for highly diverse maize- and wheat-based cropping systems, including more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations.
“Zero-tillage and residue management for cereals — that is, sowing the seed directly into unplowed soils and residues from the preceding rice crop — has been adopted on a significant area in the transact of Indo-Gangetic Plain, with positive impacts on crop yields, profitability, and resource-use efficiencies,” said Tek Sapkota, senior scientist in agricultural systems/climate change, CIMMYT.
The paper “Conservation agriculture for sustainable intensification in South Asia,” published in the science journal Nature Sustainability reported that, compared to the conventional practice, conservation agriculture resulted overall in a 4.6% higher grain yield, a 14.6% improvement in water use efficiency, and a 25.6% greater net economic return. The net economic return was 40.5% higher for full conservation agriculture but, given the benefits of partial adoption of the practices, rigid adherence to an “all or nothing” approach to spread conservation agriculture in South Asia does not seem warranted.
Conservation agriculture also offers several ecosystem services. In the study data, global warming potential was reduced by as much as 33.5% in rice-wheat systems, values that are consistent with other research. Moreover, conservation agriculture-based practices provide an economically feasible alternative to burning rice residues, a serious public health threat in northwestern India given the roughly 23 million tons of residues that are burned each year in the region.
“More widespread adoption of zero-tillage in India has been made possible with the development of next-generation tractor-drawn implements that allow direct seeding into heavy residues, as well as business models whereby implement owners contract out with neighboring farmers to sow their crops and provide other services,” said Sapkota. “National governments in South Asia are actively promoting conservation agriculture to address residue burning and other farming sustainability problems.”
Fitting conservation agriculture to maize farming in Mexico
Efforts to adapt conservation agriculture and promote its adoption by farmers operating highly-diverse, mostly rainfed maize-based cropping systems in Mexico have had mixed results. A recent study assessed soil health in 20 trials in starting between 1991 and 2016 in agro-ecologies ranging from handplanted traditional systems to intensive irrigated systems, contrasting conservation agriculture effects with those of local conventional practices, which commonly involve tillage, residue removal, and continuous maize production.
As reported in the 2021 paper “Effects of conservation agriculture on physicochemical soil health in 20 maize-based trials in different agro-ecological regions across Mexico,” published in the science journal Land Degradation and Development, conservation agriculture increased maize yields at most sites by 0.85 tons per hectare, on average. Organic matter and nitrates were higher in topsoils under conservation agriculture and soil aggregate stability was greater, meaning the soil more effectively moved air and water to plant roots. For other soil health parameters, such as nutrient content, pH, or compaction, most values were determined more by local soil type than by crop management.
“Given the significant variation across agro-ecologies, local adaptive trials are important to assess the effects of conservation agriculture on soil health and fit it to local conditions,” said Simon Fonteyne, a CIMMYT cropping systems agronomist and first author of the paper.
Emissions control
Several recent studies have assessed the costs and potential of various sustainable intensification technologies for reducing greenhouse gas emissions in India, Bangladesh and Mexico. Their findings can help inform national policies on food security, economic development and environment, including those relating to the Paris Agreement.
In the 2019 study “Cost-effective opportunities for climate change mitigation in Indian agriculture,” published in the journal Science of the Total Environment, CIMMYT and partners found that estimated total emissions from Indian agriculture were 481 tons of CO2 equivalent (MtCO2e) in 2012, with crops contributing over 40% and livestock nearly 60%. Under a business-as-usual scenario, agricultural greenhouse gas emissions in India would be 515 MtCO2e by 2030. This annual emissions could be reduced by 85.5 MtCO2e through adoption of mitigation practices and about 80% of that reduction could be achieved through measures that would actually save money and, in many cases, could be implemented with current technology. The efficient use of fertilizer, zero-tillage, and rice-water management could deliver more than 50% of the technical abatement potential.
“Realization of this mitigation potential will depend largely on the extent adoption by farmers,” said Sapkota, who was lead author of the study. “Large-scale adoption of apparently win-win options is not happening, so the government of India will need to apply appropriate policy measures and incentives, consistent with its food security and emission reduction goals.
A similar study in Bangladesh, reported in the 2021 paper “Quantifying opportunities for greenhouse gas emissions mitigation using big data from smallholder crop and livestock farmers across Bangladesh,” published in the journal Science of the Total Environment, found greenhouse gas emissions from agriculture in Bangladesh of 76.8 MtCO2e for 2014–15. Yearly emissions by 2030 under a business-as-usual approach would approximate 86.9 MtCO2e and, by 2050, about 100 MtCO2e. Adoption of realistic, climate-smart crop and livestock management options to reduce emissions offer mitigation opportunities of 9.51 MtCO2e per year by 2030 and 14.21 MtCO2e by 2050. As much as 75% of this potential can be achieved through cost-saving options that benefit smallholder farmers. As is the case for India, realization of this potential largely depends on the degree to which supportive policies and measures can encourage farmer adoption.
A similar rapid assessment of costs for to mitigate greenhouse gas emissions from crops, livestock, and forestry in Mexico found a national mitigation potential of 87.9 MtCO2eq per year, fully 72.3 MtCO2eq from livestock. As reported in the 2022 paper, “Quantification of economically feasible mitigation potential from agriculture, forestry and other land uses in Mexico,” published in the science journal Carbon Management, implementing mitigation potential on Mexican cropland could bring net benefits, compared to livestock and forestry options, which involve net costs. In the 2021 paper “Reduced Water Use in Barley and Maize Production Through Conservation Agriculture and Drip Irrigation” a reduction of emissions caused by lower fuel use in conservation agriculture of 192 kg CO2 ha−1 was measured in farmers fields, as well as an increase in soil carbon and a reduction in water use.
To provide a comprehensive overview of women and gender issues in agriculture, the Food and Agriculture Organization (FAO) recently released “The status of women in agri-food systems,” which provides compelling examples of policies and programs with a review of what has worked and specific recommendations. The report concludes that increasing women’s empowerment is essential for women’s well-being and has a positive impact on agricultural production, food security, diets, and child nutrition.
Despite the importance of agrifood systems for women’s livelihoods and the welfare of their families, women’s roles are marginalized, and their working conditions are likely to be worse than men’s–irregular, informal, part-time, low-skilled, labor intensive and thus vulnerable.
The International Center for Maize and Wheat Improvement (CIMMYT) recognizes the pressing need for gender equality measures in agri-food systems and has initiated many specific projects to address gender equality. In addition, CIMMYT is committed to introducing a gender component into all its research, programs, and interventions.
“It is an acknowledgment that gender and social equity has always been a critical component of the sustainability of any initiative, regardless of the crop and the geographic area affected,” said Bram Govaerts, CIMMYT’s Director General. “CIMMYT is now more intentional about addressing gender equality issues and we recognize the same old methods might not be the most effective.”
FAO: the collection of high-quality data are paramount for monitoring, evaluating and accelerating progress on gender equality in agrifood systems
In the past, many initiatives have relied on surveys to gather data from farmers, producers, consumers, and other stakeholders. However, in traditional rural societies, survey-based data collection might not be the best way to evaluate women’s agency, as the deeply rooted cultural restrictions might not allow them to talk openly about sensitive issues, like their relationship with a spouse.
As part of the Accelerating Genetic Gains in Maize and Wheat for improved livelihoods in Asia and Africa (AGG) project, in Bihar India, CIMMYT researchers developed an innovative storytelling approach to data collection: using vignettes, farmers are given short stories to relate to their household circumstances. Stories are also easier to remember and help build a connection with the characters quickly.
This storytelling method debunked some long-held ideas about women’s role in agriculture in this area of India, creating a more nuanced view of how and why women engage in agriculture. This method will lead to richer qualitative data, which can improve the development and sustainability of gender interventions.
FAO: Social protection programs have increased women’s employment and enhanced women’s resilience.
CIMMYT’s partnership with the Cereal Systems Initiative for South Asia (CSISA) specifically supports women farmers by improving their access and exposure to modern and improved technological innovations, knowledge and entrepreneurial skills. CSISA works in synergy with regional and national efforts, collaborating with public and private-sector partners.
FAO: interventions must be designed to close gender inequalities and empower women.
While CIMMYT has produced many improved maize varieties, CIMMYT researchers discovered that these new varieties may fall short in meeting the needs of women and the poorest of farmers. We need to explore novel approaches to evaluating farmer demand for seed, considering new questions instead of continuing to look for gender-based differences in preferences.
A first step in that direction is to determine how demand for maize seed differs among farmers according to their needs, priorities, and resource limitations. Gender is a large part of that equation, but the CIMMYT researchers also advocate for other considerations, like how maize fits into household food security and livelihoods, decision-making dynamics around maize production, and seed accessibility.
Internal efforts at CIMMYT
While the FAO report is focused on women in the agri-food system, CIMMYT has also engaged several internal initiatives to ensure a more diverse portfolio of researchers and to cultivate a stronger sense of inclusion at CIMMYT and in the wider scientific community.
At CIMMYT, between 20 and 25 percent of staff in the science career track–careers involving field, lab, data, and socioeconomic work–are female. In 2022, Alison Bentley, Director of CIMMYT’s Global Wheat Program, and Nele Verhulst, cropping systems agronomist started Women in Crop Science at CIMMYT. The group aims to connect and build a network of women in the science career track and commits to achieving a more inclusive environment at CIMMYT and within the Consultative Group for International Agricultural Research (CGIAR).
The group recently received the Inclusive Team award at the inaugural CGIAR Inclusive Workplace Awards.
CIMMYT is also helping to develop the next generation of women scientists through the annual Jeanie Borlaug Laube Women in Triticum Awards, which recognizes scientific excellence and leadership potential. To date., over 60 women scientists have received leadership training and professional development opportunities meant to support them as they join the community of scholars who are fighting hunger worldwide.

Smallholder farmers have long been considered purely subsistence producers without the capacity to participate in commercial value chains. This has led to their exclusion from many agribusiness enterprises which typically focus on medium- to large-scale growers.
Through the Accelerated Innovation Delivery Initiative (AID-I), the International Maize and Wheat Improvement Center (CIMMYT) and partners are supporting smallholder farmers to enter viable legume value chains. Soybean is one crop experiencing a rapidly expanding market. This is a unique opportunity for small-scale farmers to access a legume value chain, one that drives sustainable intensified farming for improved income and livelihoods.
In the Kasenengwa District, in eastern Zambia, Josephine Mbewe produces soybean for local oil production and grain traders who export the commodity to neighboring countries like Zimbabwe and Malawi. She is one of many farmers who are benefitting from the Agriculture Development Agent model, a concept that has been developed by CIMMYT’s implementation partner Catholic Relief Services (CRS) and scaled up in the AID-I project.
“For years we always wanted to produce for the market, but the costs were just too high. In addition, we didn’t exactly know who to sell to so this model really helps us as we sell our products locally but knowing that our aggregated produce will go to distant consumers. This model is helping us to have access to high quality inputs such as improved seed, crop chemicals, fertilizers, and other related products,” Mbewe said.
The Agriculture Development Agent model aims to create a consortium of village based agrodealers who double as seed producers multiplying seed and selling it to surrounding farmers. The same dealers buy back the grain and sell it to oil pressing companies and export commodity trading companies.
The AID-I project scales promising innovations with proven ability to address some of the systemic constraints that have discouraged agribusinesses from engaging with smallholder farmers.
“This is a model that is leveraged on community social capital where trust exists between the ADA and the local farmer,” said James Nguluwe from CRS. “Issues related to seed diversion or side marketing of the harvested crop are kept at a bare minimum as farmers don’t want to spoil their relationship with the Agriculture Development Agent and their general reputation within the community.”
“The model is also catalytic to the use of improved seed as farmers have to produce using a particular seed type. The interactions with ADA over soya seed, production and reverse purchase set up has seen the farmers extending to procure improved maize varieties as well, as opposed to times past where they would recycle seed and reap poor harvests,” he said.
Paitana Mwanza, an ADA agreed and spoke of his positive experiences of the model.
“I have had no contractual breach with the farmers. When they buy the seed, we agree on a separate grain buy back arrangement – the farmers have always delivered as per agreement.”
For years, farmers have been growing recycled seed and use of improved seed has been very uncommon among smallholder farmers. Having a financial incentive where ADAs provide an assured market is proving to be a good enough incentive to facilitate behavioral change.
Agribusiness agents face high costs associated with aggregation of produce, which the Agriculture Development Agent model overcomes. Farmers are organized and supported by ADAs, who are registered market players that have been extensively trained in business practices, seed handling and seed and grain production. As such, both grain traders and processors can make a realistic profit through this innovative system that facilitates small-scale farmers accessing new markets.
One of the key objectives of the AID-I project is to ensure that participating in market systems is a choice for smallholder farmers and exclusion from viable value chains is a thing of the past. The Agriculture Development Agent model promises to transform not only eastern Zambia but the whole country at large.
It is an important year for biofortification: 2023 will mark the 20th anniversary of this nutrition-agricultural innovation, for which its pioneers were awarded the World Food Prize.
More than three billion people around the world, mostly in Africa, Asia, and Latin America, cannot afford a nourishing, diverse diet that provides enough vitamins and minerals (micronutrients). While efforts to pursue dietary diversity—the accepted gold standard for optimal health—must continue, a healthy diet remains out of reach for a vast majority of the world’s population.
The consequences are dire. A staggering two billion people get so little essential micronutrients from their diets that they suffer from “hidden hunger”, the often-invisible scourge of micronutrient malnutrition.
To combat hidden hunger requires a range of context-specific combinations of evidence-based interventions that complement each other, including dietary diversification, supplementation, commercial food fortification, biofortification, and public health measures (like safe water, sanitation, and breastfeeding).
It is imperative to implement interventions that are practical and accessible in regions and among people most affected by hidden hunger, such as women and children in rural farming families in low- and middle-income countries (LMICs), who primarily eat what they grow. This is particularly important during periods of rapid growth and development like in the first 1,000 days of life, after which the negative impacts of an insufficient diet become largely irreversible.
In this 20th anniversary year of HarvestPlus and biofortification, we review biofortification’s role, advantages, and scale as an essential part of CGIAR-wide effort to improve global nutrition.
“Biofortified crops are going to be game-changers in dealing with… malnutrition in our world today.”
Dr. Adesina, President of the African Development Bank, World Food Prize Laureate
Staple food crops contain fewer vitamins and minerals than animal-based foods and some vegetables and fruits. Yet wheat, maize, rice, cassava, sweet potato, beans, pearl millet, and other staple foods make up the foundation of most diets around the world, and should therefore be as nutritious as possible.
Staple foods also offer nutritional protection against food systems shocks, especially for vulnerable populations who are unable to access a healthy and diverse diet, and whose reliance on staple food crops increases during times of crises. Through biofortification, staple crops can contribute a high proportion of the micronutrients needed for good health and nutrition.
Biofortification efforts to date have focused mainly on using conventional plant breeding and agronomic techniques to add more of the micronutrients most lacking in diets around the world—zinc, iron, and vitamin A— into staple crops. This approach acknowledges that many poor people cannot afford or access the variety of non-staple foods they need for optimal health, and are often underserved by other large-scale public health nutrition interventions.
“[Biofortified] crops provide a sustainable source of much needed nutrients to rural communities.”
Prof. Watts, Chief Scientific Advisor and Director for Research and Evidence, UK Foreign, Commonwealth and Development Office
Eating poor-quality, and often unsafe, food perpetuates a cycle of poverty, infection, and malnutrition. Enriching nutrients into staple crops that farmers are already eating provides a safety net against severe levels of deficiency and helps mitigate challenges of nutrition insecurity due to climate change.
CGIAR transdisciplinary, participatory, and action-oriented research and innovations to improve nutritional outcomes, including biofortification, are making a vital contribution towards realizing Sustainable Development Goal 2 to end hunger and all forms of malnutrition.
Biofortified crops are targeted mostly at rural food systems in LMICs, where deficiencies in vitamin A, iron, and zinc are highly prevalent. Young children, adolescent girls, and women are the priority groups for biofortification because their relatively high micronutrient needs predispose them to hidden hunger.
The scientific body of evidence supporting biofortification spans over two decades. Each biofortified crop is the subject of extensive research to evaluate its intrinsic nutritional value and its potential impacts on human nutrition and health.
Vitamin A orange sweet potato (OSP) was the first biofortified staple to be delivered at scale and evaluated in sub-Saharan Africa, a joint effort by HarvestPlus, the International Potato Center, and the International Food Policy Research Institute. It has very high levels of vitamin A (traditional white varieties contain none) and long-term studies indicate it can help reduce diarrhea in children and is a cost-effective way to improve population vitamin A intake, thereby improving child and maternal health and reducing the likelihood of vitamin A deficiency. Breeding efforts are now simultaneously increasing the iron content of OSP, to deliver more of multiple stacked micronutrients.
Evidence from additional randomized controlled trials have demonstrated that nutrient-enhanced staple crops generate positive direct and indirect health effects on multiple age groups, for example:
Supplementation studies have clearly shown that improvements in micronutrient status, particularly zinc, vitamin A, and iron status, generate improvements in immunity, growth, and multiple other dimensions of good health. The improvements are not specific to how the micronutrients are delivered (e.g., by food or pills), but rather due to positive changes in nutritional status.
“The reason for growing these varieties, is better yield, more profitability and better zinc nutrition for our families.”
— Mr Tariq, Pakistani farmer
Adoption of biofortification is demand driven. All released biofortified varieties are agronomically competitive in the agricultural zone(s) for which they were developed, relative to the varieties farmers already grow.
Crop breeding efforts are responsive to the expressed priorities and preferences of farming families and their countries. High yields are among the traits considered non-negotiable by breeders and farmers alike, and are a driver for national authorities to approve the release of new varieties in their countries to farmers to grow them.
“[Nyota, an iron bean] can easily give me over 3 tons per hectare, as compared to other varieties that yield about 2 tons.”
— Mr Burde, Kenyan seed producer
Breeding pipelines are dynamic and always adapting to new stresses. Nutrient-enriched varieties of crops are continuously improved by breeders who breed varieties for progressively higher levels of micronutrients, which are also agronomically competitive (e.g., disease and pest resistant), well adapted to a wide range of climatic conditions (e.g., drought and heat tolerant), and exhibit food quality traits desired by farmers, food processors, and consumers (e.g., fast cooking time and good taste).
In Pakistan, one of the highest wheat-consuming countries in the world, the zinc wheat variety Akbar-2019 is now a ‘mega-variety’. It provides 30 percent more zinc and 8-10 percent higher yield than previous popular varieties. Developed by the International Maize and Wheat Improvement Center (CIMMYT) in partnership with HarvestPlus, and released by the Wheat Research Institute of the Ayub Agricultural Research Institute, Faisalabad, Akbar-2019 is also resistant to rusts and well adapted to a range of sowing dates. Farmers attest to the good quality of the chapatti (flat bread) made from its flour. Akbar-2019 is already being grown on more than three million hectares of land—and soon an estimated 100 million people will eat chapatti made from its flour and reap the benefits of added zinc in their diets.
“My father-in-law… has expressed a desire to continue growing only biofortified zinc wheat from now on. In addition to the grain quality, the plants also grow well in tough geographical conditions.”
— Ms Devi, Indian farmer
In Nigeria, HarvestPlus and partners including the International Institute of Tropical Agriculture have developed varieties of vitamin A cassava with multiple traits attractive for farmers. Survey data indicates vitamin A cassava varieties have an average fresh root yield of 20.5 metric tons per hectare (MT/Ha), well above the average yield of 10.2 MT/Ha of other improved but non-biofortified varieties. Nearly 2.1 million farmers are growing vitamin A cassava in Nigeria, providing added dietary vitamin A to over 10 million people in a country where vitamin A deficiency is a severe, yet preventable, public health problem.
To establish new crops with higher levels of micronutrients, breeders tap into the spectrum of genetic diversity stored within global plant gene banks to find nutrient-dense qualities from underutilized plant species (including wild species or those naturally evolved in certain geographic areas).
Through breeding for improved nutrition, biofortification also transfers otherwise untapped variation for traits other than micronutrients into newly developed crops, increasing the genetic agrobiodiversity not only in biofortified varieties, but also non-biofortified varieties derived from crossing micronutrient-dense plant ‘parents’ to produce high micronutrient ‘offspring’.
Micronutrient genes are not subject to erosion in the breeding process (as genes are for disease or pest resistance), like the dwarfing genes in wheat and rice that catalyzed the green revolution.
CGIAR has committed to mainstreaming improved nutrient traits in most of their breeding lines through crop breeding, given its proven cost-effective and sustainable approach to enriching staple food crops.
Governments and other “Our aim should be to make every family farm a biofortified farm.”
— Dr MS Swaminathan, World Food Prize Laureate, Father of Indian Green Revolution
HarvestPlus partners, collaborators, and advocates support country-level initiatives that promote the integration of biofortified seeds, crops, and foods into local, national, and regional policies and programs. These collective efforts and alliances are the catalyst behind the scale up to over 86 million people in farming households eating nutrient-enriched foods in 2022, 22% more than in 2021.
In 2022, a declaration adopted by the African Union to scale up food fortification and biofortification in Africa—to make nutrient-rich foods sustainably available, accessible, and affordable—was centered on ensuring healthy diets reach those who need them most.
The Government of DR Congo has committed to scaling biofortified crop adoption and production, and its integration into the wider food system. Biofortified crops are included as one component of a wide-reaching, multi-sectoral nutrition program, funded with a loan from the World Bank.
In India, the Indian Council of Agricultural Research established minimum levels of iron and zinc to be bred into national varieties of pearl millet. The All-India Coordinated Research Project on Pearl Millet encouraged National Agricultural Research Systems to begin breeding programs for micronutrients along with higher yields in 2014. Joint efforts by the International Crops Research Institute for the Semi-Arid Tropics and HarvestPlus to enhanced the levels of iron in pearl millet have brought notable endorsement of biofortification by the Honorable Prime Minister Modi as a solution to address malnutrition.
The Copenhagen Consensus, a global research think-tank and policy advisory group, assessed biofortification and concluded for every USD 1 spent on biofortification, as much as USD 17 in benefits could be generated, and deemed biofortification, supplementation, and fortification as some of the smartest ways to spend money and advance global welfare.
Systematic reviews and ex-ante (before intervention) analyses of several micronutrient-crop and country scenarios have shown that biofortification is highly cost-effective when measured by the World Bank’s criteria of cost per Disability-Adjusted Life Year (DALY) saved. These analyses show biofortified crops to be in the range of USD 15-20 per DALY saved—far below the World Bank’s cost-effectiveness threshold of USD 270 per DALY.
“Patience, perseverance, and vision are required to achieve the cost-effectiveness of linking agriculture and nutrition in general, and biofortification in particular. The donors to the CGIAR system realized this by continuing investments well after the 20th anniversaries of CIMMYT and the International Rice Research Institute.” — Howarth (Howdy) Bouis, HarvestPlus Founding Director, World Food Prize Laureate
The number of vulnerable rural families and communities growing and benefiting from nutrient-enriched crops has significantly increased year over year. Today, over 86 million people in farming households are eating biofortified foods—progressing rapidly towards 100 million in later 2023.
Eliminating malnutrition requires multiple solutions, and biofortification is an extremely important part of CGIAR’s efforts in pursuit of this goal.
Research has proven biofortification to be an efficacious, cost-effective, and scalable innovation that can play a pivotal role in transforming food systems to deliver affordable and accessible nutritious food for all.

Numerous actors — from African startups to global humanitarian organizations — are responding to the continent’s food challenges. For Sub-Saharan Africa to meet its food needs as climate change persists, the region must first overcome some basic hurdles.
Harisankar Nayak, a CIMMYT supported PhD student, received significant honors from the Government of India for his PhD thesis. The Indian Council for Agricultural Research (ICAR) – Indian Agricultural Research Institute (IARI) recognized Nayak’s exceptional academic performance and thesis work during the 61st convocation ceremony held in New Delhi on February 24, 2023. The Vice President of India, Shri Jagdeep Dhankhar, presided over the ceremony. Nayak was awarded the IARI Merit medal for his thesis, “Machine learning evidence-based agronomic practices for higher yield and lower emission in rice-wheat system,” published in the esteemed journal Field Crops Research.
Nayak’s research involved comparing multiple machine learning methods to identify the primary drivers and causes of wheat yield variability in northwestern India. His findings provide important methodology to identify variables involved when one farm’s yield is less than a similar farm in the same area. With these variables classified, policymakers, government ministries, and farmers themselves can take steps to raise yield, sustainably, across the entire north-western Indo-Gangetic Plain.
Timothy Krupnik, Country Representative for Research and Partnerships and Systems Agronomist at CIMMYT-Bangladesh, and Nayak’s PhD supervisor from CIMMYT, expressed his pride in Nayak’s achievements. “I saw first-hand how much work he put into his research, and he richly deserves this honor. The same was opined by Dr C. M. Parihar, Nayak’s supervisor from IARI, Dr. M.L. Jat, former principal scientist, CIMMYT-India and Dr T B Sapkota, senior scientist, Agricultural System/Climate Change, CIMMYT. In addition, this is an excellent example of the capacity development work arising from CIMMYT’s collaborations with ICAR and IARI.”
Nayak also led research examining the sustainability of rice production in the same area of India, which determined that nitrogen use could be reduced without impacting rice yields. “To be recognized by ICAR and IARI, among many other worthy students, is a great honor,” said Nayak. “CIMMYT provided crucial material support, helping me facilitate my research. Just as important were the opportunities to collaborate with CIMMYT scientists.” Nayak’s work is vital for addressing the challenges posed by a changing climate and feeding a growing population.
As part of its crucial mission to accelerate wheat adaptation to rapidly changing climate conditions due to global warming, the Heat and Drought Wheat Improvement Consortium (HeDWIC) with the support of the Foundation for Food & Agriculture Research (FFAR) has granted 10 awards since 2021, crowdsourcing innovative research from around the world.
Like other crops, wheat – which makes up 20 percent of the human diet – is affected by threats to the global food system from persistent population growth and economic and climate pressures. These challenges are further exacerbated by the fallout from the COVID-19 pandemic and the war in Ukraine. There is an urgent need to prioritize climate resilient wheat varieties to protect this food staple.
Some five years after HeDWIC was launched in 2014 to incorporate the most advanced research technologies into improving heat and drought tolerance of wheat, the Intergovernmental Panel on Climate Change reported that climate change was having an impact on food security through increasing temperatures, changing precipitation patterns and greater frequency of extreme weather events in its Special Report on Climate Change and Land.
“While some areas are becoming more conducive to wheat growing, crop yields are suffering in other regions around the world traditionally known as bread baskets,” said wheat physiologist Matthew Reynolds, who leads HeDWIC at the International Maize and Wheat Improvement Center (CIMMYT).
“Wheat is one of our fundamental crops, and we must spare no effort in protecting it from current and future challenges,” said Saharah Moon Chapotin, FFAR executive director. “Global collaborations are necessary to address global concerns, and these grants are bringing together international teams to share and build the science and research that will ensure the stability of this crop.”
The 10 recipient projects are under the umbrella of the HeDWIC project Harnessing Translational Research Across a Global Wheat Improvement Network for Climate Resilience, funded by FFAR. The first five awardee projects were identified in 2021, and an additional five projects were awarded in 2022.
To boost new ideas in “climate-proofing” crops, HeDWIC conducts virtual meetings that include all awarded research teams to take advantage of the collective global expertise in heat and drought resilience, leading to cross-pollination of ideas and further leverage of resources and capabilities.
In March, Reynolds led in-person discussions with some of the collaborating researchers at CIMMYT’s experimental research station on the outskirts of Ciudad Obregon, a city in Mexico’s Sonoran Desert, during CIMMYT’s annual Visitors’ Week.
Projects awarded in 2022
“The HeDWIC mini proposal allows us to explore the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat. The controlled irrigation conditions for wheat grown in Obregon give us the opportunity to quantify photosynthesis by fluorescence while drought develops. Detecting a drought-specific fluorescence response and/or the interaction between active and passive fluorescence is relevant for breeding selecting purposes as well as large spatial scale detection of drought by monitoring the plant.” – Onno Muller, Forschungszentrum Jülich, Institute of Bio- and Geosciences, Germany
“Heat stress during grain filling can restrict the availability of carbohydrates needed for grain development. India has been experiencing sudden spikes in both minimum and maximum temperatures by 3 to 5 degrees above normal from late-February onwards, which is an important time for wheat grain-filling and has resulted in declining wheat productivity. Our team is examining the ability of pre-flowering nitrogen applications to support biomass accumulation and overcome the grain-filling source (carbohydrate) limitation during heat spikes. If successful, the results could have broad-reaching benefits given that farmers are familiar with and well-skilled in using nitrogen applications regimes in crop management.” – Renu Pandey, Division of Plant Physiology, Indian Agricultural Research Institute
“The HeDWIC funding provides a unique opportunity to test how the regulatory sugar, trehalose 6-phosphate (T6P) can protect wheat yields against increasingly common chronic and acute heat stress events. We have already shown that T6P spray increases wheat yields significantly in field conditions under a range of rainfall in wet and dry years. With increasing likelihood of heat stress events in the years ahead, in unique facilities at CIMMYT, we will test the potential of T6P to protect reproductive development from catastrophic yield loss due to chronic and acute heat.” – Matthew Paul, Rothamsted Research, UK
“Over the last decade, we have developed heat tolerant wheat germplasm at the University of Sydney that maintains yield under terminal heat stress. In our new HeDWIC project, this material will be tested under combined drought and heat stress under field conditions. This will provide plant breeders with highly valuable information on field tested germplasm for use in accelerated breeding programs targeting combined heat and drought tolerance. The work is critical for future food security considering the inextricable link between temperature and plant water demand, and the increased frequency and intensity of heat and drought events under projected climate change.” – William Salter, University of Sydney, Australia
“Wheat Rht-1 dwarfing genes were an essential component that led to spectacular increases in grain yields during the Green Revolution. Although Rht1 and Rht2 are still used widely in wheat breeding 50 years after they were introduced, they are suboptimal under drought conditions and are often associated with a yield penalty. Using a more extensive range of Rht-1 dwarfing alleles that were developed at Rothamsted, we will introduce them into CIMMYT germplasm to optimize biomass and ultimately increase grain yields under drought stress.” – Steve Thomas, Rothamsted Research, UK
Additional comments from 2021 awardees
“This opportunity has enabled the collection of significant amounts of data that will contribute to the advancement of knowledge in crop physiology and root biology. It has also provided early career researchers with opportunities to gain hands-on experience, develop important skills, and grow their networks. Additionally, this initiative has stimulated further ideas and collaborations among researchers, fostering a culture of innovation and cooperation that is essential for progress.” – Hannah Schneider, Wageningen University & Research, Netherlands
“The project is a unique opportunity for research groups from around the world to coordinate efforts on identifying ways to improve heat tolerance of wheat.” – Owen Atkin, Australian National University, Australia
“It is important to understand how high temperature limits crop growth and yield and to identify genetic variation that can be used for breeding climate resilient crops. This project has already begun to develop new methods for rapidly screening growth and physiological processes in genetically diverse panels which we hope will be invaluable to researchers and breeders.” – Erik Murchie, University of Nottingham, UK
“This project will provide novel phenotyping screens and germplasm to breeders and lay the groundwork for genetic analysis and marker development.” – John Foulkes, University of Nottingham, UK

ABOUT CIMMYT
The International Maize and Wheat Improvement Center (CIMMYT) is an international organization focused on non-profit agricultural research and training that empowers farmers through science and innovation to nourish the world in the midst of a climate crisis. Applying high-quality science and strong partnerships, CIMMYT works to achieve a world with healthier and more prosperous people, free from global food crises and with more resilient agri-food systems. CIMMYT’s research brings enhanced productivity and better profits to farmers, mitigates the effects of the climate crisis, and reduces the environmental impact of agriculture.
CIMMYT is a member of CGIAR, a global research partnership for a food secure future dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources.
Senior government officials in Zambia have embraced the rollout of the International Maize and Wheat Improvement Center’s (CIMMYT’s) new innovations which target smallholder farmers and agriculture-based value chain actors in the country.
On January 17, 2023, CIMMYT Director General Bram Govaerts met with Minister of Agriculture Reuben Mtolo Phiri. The Minister reassured Govaerts that the investments made by CIMMYT in the country had the Government’s full support.
Earlier this year, a delegation led by Cary Fowler, the US Special envoy for Global Food Security met the Minister and his team at the Government complex in Lusaka, Zambia’s capital, to deliberate on a variety of agriculture development issues concerning the country.
Govaerts’ visit came off the back of the new Accelerated Innovation Delivery Initiative (AID-I), a CIMMYT-led project funded by the United Stated Agency for International Development (USAID). The project seeks to scale up promising innovations that could transform the maize and legume value chains within the southern African region, with a focus on Zambia, Malawi and Tanzania.
“As the Government of Zambia, we intend to create a private sector driven economy for which agriculture plays a critical role. Having progressive partners like CIMMYT helps us achieve this cause and this new program is received with open arms,” said Phiri.
The aims of the AID-I project include strengthening seed systems, the promotion and adoption of stress-tolerant maize and legume varieties, demonstration of good agriculture practices that respond to the effects of climate change and addressing systemic constraints in maize and legume value chains.
Through AID-I, CIMMYT experts are working with over 20 global, regional, national and local partners including the Alliance for a Green Revolution in Africa (AGRA), Catholic Relief Services (TLC), Total Land Care (TLC), the International Water Management Institution (IMWI) and World Vegetable Center.
Also attending the meeting was AID-I Technical Lead and CIMMYT Scientist Hambulo Ngoma who discussed some of the latest project activities.
“As this project focuses on accelerated delivery, we have set up more than 40 demonstrations in eastern Zambia with the intention of showcasing stress-tolerant varieties for maize and legume under conservation agriculture. In addition, we are showcasing other good agriculture practices such as strip cropping which not only enhances intensified crop production but is a biological control for fall armyworm,” Ngoma said.
The Minister appreciated the rationale of the project and indicated that participatory variety selection for farmers was crucial if they were going to maximize their yields and returns from farming.
Phiri further emphasized that CIMMYT and partners’ investment in legume value chain strengthening came at a welcome time as upscaling soya bean production was a key priority in the Government’s strategic plan for agricultural development because of its export-ready market within the region.
“Markets such as Zimbabwe, Mozambique and Tanzania can readily take up the soya we produce, and we are looking to export legumes such as soya and groundnuts to East Africa. This project therefore fits very well within our strategic road map,” Phiri said.
The demonstration plots set up by CIMMYT experts will help farmers grow the right varieties for their agro ecologies and have greater response capabilities to the export market opportunities the Government is facilitating.
The Minister also indicated that he hoped CIMMYT would assist in strengthening the country’s capacity to deal with fall armyworm. CIMMYT Global Maize Program Director B.M. Prasanna reassured Phiri that through the Zambian Agriculture research Institute (ZARI), CIMMYT had already released three fall armyworm-tolerant varieties. He also discussed how the AID-I project would be instrumental in scaling up their uptake, especially amongst smallholder farmers who have minimal disposable income to buy enough pesticides to control the pest.
Concluding the meeting, Govaerts spoke of CIMMYT’s commitment to supporting Zambia achieve its food security and agricultural export goals.
“As CIMMYT, we want you to recognize us as a listening partner. We are of the conviction that we can only combat climate change and achieve shared prosperity through the strength of convening power, where we leverage on each other’s strength.”
As the project is focused on scaling existing promising technologies and innovations, rapid transformative results are on the horizon for the people of Zambia.
Leading scientists, practitioners and representatives of development agencies, and international and non-governmental organizations reimagine the path to achieve Zero Hunger at a time when recurring crises driven by food insecurity, climate change and conflict stretch both emergency response and development efforts to the limit.
The exercise aims to trigger disruptive thinking around how long-term development investments can help build more resilient communities. Stronger cooperation mechanisms between the humanitarian and development sectors are necessary to break the cycle of recurrent crises by building local agency and capacities. Aid and development beneficiaries in vulnerable communities must be front and center in every effort seeking to achieve a hunger free and sustainable planet.
The brief has been endorsed by a group of experts who participated in the 2022 Borlaug Dialogue of the World Food Prize in Des Moines, Iowa.
How can we overcome the primary obstacles to a food secure, resilient, and inclusive world?
The first challenge involves addressing fractures between aid and development organizations that work in silos without sharing information, objectives, learnings, and resources. The authors make a strong case for increasing cooperation – rather than competition – to confront the intricate and interconnected challenges of climate change, food insecurity and conflict.
In addition, they advocate for more ambitious and community-centered interventions that prioritize systemic change over emergency responses to food crises. The change of perspective implies shifting the emphasis from addressing immediate humanitarian needs to investing in long-term resilience.
The third recommendation is to phase out outdated top-down planning and policy-making processes that fail to align with community needs, delegate decisions or transfer resources directly to partners on the ground. Listening to the needs of beneficiaries and affected communities from the start of any intervention is considered the most significant step to achieve lasting change.
CIMMYT and partners are leading by example and catalyzing change in sub-Saharan Africa
With funding from the United States Agency for International Development (USAID), CIMMYT and other CGIAR centers, in partnership with innovation generators and organizations on the ground, will develop and scale up solutions for transforming farming systems by implementing the Accelerated Intervention Delivery Initiative (AID-I) in Malawi, Tanzania and Zambia, and the Sustainable Agrifood Systems Approach for Sudan (SASAS). Both initiatives answer the need for stronger cooperation between the humanitarian and development sectors by creating a common space where aid and research organizations work together on the ground to address the urgent and long-term needs of vulnerable communities to their mutual advantage.
These CIMMYT-led projects will establish innovation hubs or networks for developing, testing, and adapting sustainable farming practices and technologies to the needs of local farmers actively engaged in participatory research and extension activities, building cooperative relationships, and leveraging the existing collaboration between One CGIAR research systems. As a result, co-creation between partners and project beneficiaries is at the heart of every research activity, co-development process and scaling endeavor.
AID-I will adopt market-based approaches to provide critical information and innovations to 3 million smallholder farmers, who will maintain or increase local food production and mitigate the impacts of the global food, fuel, and fertilizer crises. Small and medium sized enterprises will be supported to strengthen innovative approaches to agricultural value change development, creating agricultural systems that are built for long-term resilience and success.
Similarly, SASAS will take a multi-crop approach focusing on soil fertility management to achieve productivity gains and inclusive agriculture-led economic growth in the Greater Khartoum, Blue Nile and South Kordofan regions of Sudan. CIMMYT will leverage on-the-ground partnerships to adapt and replicate previously successful Integrated Agrifood Systems Initiatives (IASI) projects, empowering communities to ensure the agricultural transformation works for their needs.
Ultimately, both initiatives shift their focus from crisis response to building long-term resilience and aim to achieve rapid but lasting climate-smart impacts that demonstrate the power of small-scale agriculture as a major driver of transformative change by expanding access to improved technologies, tools, and information in sub-Saharan Africa.

Scientists at the International Maize and Wheat Improvement Center (CIMMYT) are helping to scale up wheat production and productivity in Malawi.
The political conflict between Russia and Ukraine has disrupted food supply chains globally and Malawi’s wheat supply has been adversely affected. As a response, Pyxus Trading, the biggest agribusiness private company in Malawi, has endeavored to partner with CIMMYT to accelerate the growth of wheat production in the country.
At a recent visit by CIMMYT’s Director General Bram Govaerts, the executive management of Pyxus provided detailed updates of how CIMMYT has facilitated access to 100 improved wheat varieties now undergoing trials in Malawi. The visit was part of the Accelerated Innovation Delivery Initiative (AID-I), a new project funded by the United States of Agency for International Development (USAID).
Attending the Pyxus field visit was United States Department of State Special Envoy for Global Food Security Cary Fowler, Dina Esposito, Assistant to the Administrator at USAID Bureau of Resilience and Food Security, and other USAID staff.
Speaking at a field tour this January at the Pyxus farm headquarters, Commercial Manager John Gait expressed the importance of achieving self-sufficiency in countries like Malawi.
“It’s become very apparent with the global supply chain disruptions of wheat and related commodities that countries like Malawi should rise to a level of self-sufficiency for strategic commodities such as wheat,” Gait said. “Through the help of CIMMYT, we managed to obtain materials for 100 varieties which we have put under trial. Our objective is to select varieties that are most adapted to our agroecology and provide us with satisfactory yields and grain quality sufficient for our processing ambitions.”
CIMMYT Sustainable Agrifood Systems (SAS) Director Sieg Snapp affirmed CIMMYT’s support for private sector companies like Pyxus.
“When they told me they were searching for high performing genetic materials I told them about the Global Wheat Program and how such material could easily be obtained from our headquarters in Mexico,” Snapp said. “I immediately facilitated linkages between Pyxus and CIMMYT headquarters which saw the quick delivery of the varieties. Considering that it was quite recent, I am impressed to see that the trials are already so well established.”
Achieving global food security will require cooperation and collaboration between partners from different sectors. One of CIMMYT’s strategic thrusts is to encourage public-private partnerships where national governments can leverage on the competencies and capabilities of the private sector.
“We aim to be catalytic in all our functions. We believe we have a critical role in ensuring that countries like Malawi have access to the best genetics to ensure that they meet their food requirements. I am happy Pyxus identified us a strategic partner to work with in their wheat program, and through working hand in hand with the government and other key players, the quest to achieve food self-sufficiency can have a shortened pipeline,” Govaerts said.
In addition to witnessing the wheat trials, Govaerts received a tour of the entire Pyxus operations which included the groundnut and forestry operations. Pyxus staff each took turns explaining the various business models the company was employing to contribute to Malawi’s export earnings and food security.
As a commitment to help Malawi realise increased wheat production, CIMMYT will be closely following the Pyxus trials and providing technical support to ensure that the best varieties adopted are rapidly scaled.
