CIMMYT’s work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.
Umm Zeina, a 40-year-old farmer living in El Nahal, in Sudan’s Gadarif State, was not happy with her yield, blaming the poor seeds and traditional techniques she was using. This was until she participated in the extensive seeds production training program organized by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).
“We learned a lot on how to produce seeds and how to control the parasite Striga mixed with crops. The training draws our attention to the fact that the availability of quality seed is the foundation for food production and productivity. As traditional farmers, we had very poor information about the availability, characteristics, and prices of seed of improved varieties,” Umm Zeina stressed.
ICRISAT’s extensive training attracted more than 350 (68 female) seed producer farmers from El Fashaga and El Nahal localities aimed at helping seed producers provide seeds of appropriate varieties for use by different categories of farmers. Farmers were also trained in better selection, treatment, and storage of seed from their own farms. The training also focused on the production of disease-free seeds to support agricultural productivity and success. The training helped to enhance farmers’ demand for improved seeds and eventually aimed to deliver improved seeds to more than 6000 farmers in El Fashaga, El Nahal and other neighboring localities.
This training was held as part of CIMMYT’s Sustainable Agrifood Systems Approach for Sudan (SASAS) program, which empowers farmers and herders to reduce the need for humanitarian assistance even in conflict-affected Sudan. In the context of the atrocious food crisis in Sudan, SASAS and partners work to ensure that farmers produce the quality seeds they need to enhance food production amid escalating conflict.
In El Fashaga and El Nahal localities, the seeds production training focused on sorghum, as this crop is widely adapted and drought tolerant as well as it is a staple crop to strengthen food security and contributes to agricultural diversity and economic growth in the regions where it is cultivated.
“During the training, we learnt a lot on how to choose the best seeds to produce improved seeds and how to choose the land, isolation area, and cleanliness to harvest. I was extremely interested to learn more about how to keep the seed to its purest form for replanting purposes and human or animal consumption,” said Tarig Hassan, a farmer living in El Nahal locality.
The seeds production training also aimed at maintaining seeds quality control through training and regulatory systems, and how to multiply and distribute seeds in a timely manner and at a price affordable for farmers. Farmers also learnt to use a revolving seed mechanism to make available seeds for many new seed producer farmers for the next season through farmer-to-farmer seeds distribution.
“The seed production training is not only on how to produce quality seeds and protect loss of seeds, but also about the use of diversified seeds of sorghum, millet and ground nut that serve for both food and nutrition security”, said Gizaw Desta, Senior Scientist in ICRISAT.
SASAS’s objective is to improve food security and access to income-generating opportunities through the adoption of sustainable agriculture practices and the promotion of agri-processing and post-harvest management. It focuses on supporting smallholder crop and livestock farmers to adapt their farming activities to climate change and abiotic pressures by diversifying their crops to further cushion themselves from climatic vagaries, reduce post-harvest loss, and improve market participation, and functionality. Women and youth are supported through training and agricultural and veterinary inputs to increase income generation activities and access to economic resources.
“At SASAS, we strive to train farmers in basic farm seed production. This helps preserve and expand the diversity of the seed on which our food systems in Sudan rely. Considering the dire food security situation in the country, we fully encourage farmers to be engaged in seeds production to provide different and improved seed varieties,” said Abdelrahman Kheir, SASAS Chief of Party in Sudan.
SASAS works with ICRISAT to uplift smallholder farmers and ensure food security in semi-arid tropics. SASAS partners are committed to elevating crop productivity, resilience, and sustainability vital to dryland communities’ prosperity. This steadfast commitment profoundly affects millions in the world’s most challenging agricultural regions.
Food security in the prevailing uncertain climatic and economic conditions can only be guaranteed by deliberate actions toward maximizing production, especially in stress-prone environments. The main priority of the CGIAR and NARS breeding programs is to enhance genetic gain in crops through the assessment of seed varieties with drought-resilient, nutritional, and yield traits. This is achieved by leveraging data-driven approaches and embracing contemporary tools and methodologies.
Innovative approaches such as molecular tools, doubled haploid technology, and refined breeding schemes have greatly contributed to the strides made in CIMMYT’s endeavor to elevate genetic gain within breeding pipelines. These advancements not only drive improved productivity but also promise cost-effective strategies for navigating the challenges posed by climate variability.
Molecular Tools
In maize breeding, traditionally, at each stage of the pipeline, entries are grown in multi-location trials. Phenotyping in multiple environments helps to select the best entries not only based on their genetic values but also on environmental factors and their interaction with diverse environments. However, this is also a labor-intensive and time-consuming step in the breeding pipeline. Molecular breeding offers a transformative solution by expanding breeding programs while minimizing phenotyping requirements. It is a well-known fact that trait phenotype results from both genetic and non-genetic factors, with genetic factors being contributed by the expression of genes at the DNA level.
Identifying genomic regions close to causative genes for traits of interest, such as high yield, disease resistance, or quality, can help to incorporate desirable genes/alleles into selected elite genotypes. DNA-based markers aid in efficiently tracking the inheritance of genetic traits, thereby facilitating the selection of desired traits in breeding programs. Marker-assisted forward breeding accelerates the selection of plants with desired traits by identifying the genetic markers associated with those traits. With such harnessed genotypic information, breeders can pre-select genetic material before embarking on the resource-intensive phenotyping stages. This strategic utilization of molecular markers, particularly in identifying susceptibility to key diseases like maize streak virus (MSV) and maize lethal necrosis (MLN), enables the judicious allocation of resources for phenotyping.
Figure 1. Summary of marker-assisted forward breeding across six breeding pipelines for MLN- and MSV-resistance haplotypes over the past six years.
Since 2018, CIMMYT has been implementing marker-assisted forward breeding for MSV and MLN. Since then, more than 100,000 pure breeding lines have been tested by examining their favorable haplotypes with a small set of 10 genetic markers and discarding the lines carrying unfavorable haplotypes for MSV and MLN resistance. In the last six years, nearly 30,000 lines have been rejected before undergoing field testing. In southern Africa, for instance, a rapid response to seed movement using molecular and serological techniques prevented the spread of MLN and facilitated the incorporation of resistance traits into new plant varieties.
Most hybrids in the final stages of breeding pipelines are passed through forward breeding. While Fall Armyworm, Gray Leaf Spot, common rust, and Turcicum Leaf Blight also cause substantial yield reductions in sub-Saharan Africa, research carried out under the AGG project indicates that the genetic makeup of these traits is oligogenic, governed by both moderate and small effect quantitative trait loci (QTLs), but lacking a single major-effect QTL and not amenable to forward breeding. This means that their resistance is influenced by complex multiple genetic factors, rather than being primarily controlled by a few major genetic regions. Alternatively, these biotic stress traits can be improved effectively through genomic selection.
Genomic selection is used to improve complex traits that are controlled by many small-effect QTLs. This approach does not require prior genetic information about the trait of interest and uses genome-wide marker information to estimate all marker effects and select individuals with high genomic-estimated breeding values (GEBVs). This means it uses data from various genetic markers to predict which individuals are likely to have desirable alleles for MSV and MLN. Genomic selection is being applied for grain yield under drought stress, and efforts are underway to extend its application to address more complex challenges related to plant diseases and pests. Foliar diseases are moderately complex traits.
Proof of concept on applying genomic selection for foliar diseases like gray leaf spot and northern corn leaf blight showed high prediction accuracies, supporting the implementation of genomic selection together with forward breeding for other traits at the early stage of the breeding pipeline. Implementing genomic selection for GY under optimum and drought management proved that maize breeders could obtain the same gain as with conventional breeding, where all entries are phenotyped in the field, but at approximately 35-40% less cost. Many candidate hybrids now entering the advanced stages of the breeding pipeline were developed using genomic selection. Several of our earlier studies (Beyene et al., 2015, 2016, 2019, 2021; Chaikam et al., 2019; Crossa et al., 2017; Prasanna et al., 2022; Vivek et al., 2017) showed that breeding pipelines achieved high genetic gain by adopting new molecular tools, thus confirming the benefit of adopting molecular breeding tools.
Currently, in CIMMYT’s eastern and southern breeding pipelines, all product profiles are using genomic selection at stage I, where the training population is evaluated in multiple locations with a sparse design, estimating the GEBVs for the unphenotyped lines, and using GEBVs and phenotypic BLUPs of test crosses in the selection for stage II. This process allows the handling of a large number of lines at stage I with a fixed budget without losing selection accuracy. Since 2017, we have used the “test half and predict half” strategy (Figure 2), where all the lines were genotyped with mid-density markers, and the selected ~50% of the total stage I lines were testcrossed and evaluated in multiple locations to be used as a training population to estimate the GEBVs for the other 50% of the unphenotyped lines for the traits of interest. High prediction correlations were observed in three selected product profiles for GY under optimum, managed drought, and low soil N conditions (Figure 3).
Genomic selection is also implemented to reduce the breeding cycle. However, our final products are three-way cross hybrids, where genomic selection is applied only to select the best line rather than selecting the best hybrid combinations. Historical data were used to test the possibility of reducing the breeding cycle. However, our results showed that the use of historical data to predict 100% of lines from the current year yielded low to moderate prediction correlations both under optimum and drought conditions for GY, anthesis date, and plant height (Figure 4). Incorporating 10 to 30% of the testing population into the training population leads to high prediction correlations. This concludes that by using historical data, the training population, which needs to be test-crossed and evaluated in multiple locations every year, can be reduced from 50% to 10-30%, which helps breeders allocate the saved resources to evaluate more lines without losing prediction accuracy.
Doubled Haploid Technology
Doubled haploid technology speeds up the creation of inbred lines by producing entirely uniform lines. Pedigree line development is a traditional method in plant breeding aimed at gradually improving and stabilizing the genetic makeup of the new variety over time. It involves multiple generations of controlled crosses between parent plants with known characteristics. Each subsequent generation is carefully selected based on specific traits of interest, such as yield, disease resistance, or quality. Pedigree line development is expensive, particularly when nurseries are in remote locations.
Unlike traditional methods where some genetic variation remains, doubled haploid lines are completely homogeneous. This means that there is increased heritability of desirable traits and improved accuracy of selection. Doubled haploid technology, which is more compatible with the use of molecular markers, simplifies breeding processes and shortens the time needed to develop inbred lines (Chaikam et al., 2019).
The first doubled haploid facility in Africa was established in 2013 and is extensively used by the CGIAR, NARES, and the private sector. Over the past five years, 1,349 populations have been induced and more than 223,144 doubled haploid lines delivered to breeding programs from CGIAR, NARES, and the private sector in sub-Saharan Africa. Shifting from traditional pedigree-based breeding to doubled haploid technology has shown a high impact on key breeding metrics (gain per cycle and gain per year) not only in CIMMYT but also in national partners’ breeding programs, thus increasing genetic gain within the available budget.

The Africa-China-CIMMYT Science Forum in Nairobi gathered experts from China and Africa to explore strategies for transforming agrifood systems through innovation and cooperation. Organized by CAAS and CIMMYT, the forum emphasized the importance of collaboration in addressing food security, rural poverty, and climate resilience in Africa. Key discussions focused on the benefits of technology transfer and research partnerships to support smallholder farmers and advance agricultural modernization across the continent.
Maize production in Kenya is a critical component of the country’s agriculture and food security. However, climate change poses a serious threat to its production. Changes in temperature and precipitation patterns can affect maize growth, reduce yields, and increase the incidence of pests and diseases.
Prolonged droughts and unpredictable rainfall can lead to crop failures, while extreme weather events can damage crops and infrastructure. As the climate continues to change, it is essential for Kenyan farmers to adopt resilient agricultural practices and more adapted seed products to safeguard maize production and ensure food security for the population.
For decades, seed companies as well as governments and donors have invested in maize hybrid breeding. Dozens of new hybrids have been made available to seed companies throughout East Africa for multiplication and distribution. These hybrids are designed and tested to outperform older hybrids in terms of yield under rainfed conditions, to include tolerance to drought and pests.
However, the potential impact of these investments has been hampered by the slow turnover of hybrids among farmers. Research has shown that, despite the availability of newer, higher-performing varieties, farmers tend to purchase older, less productive hybrids. The ‘turnover problem’ in Kenya has been described by CIMMYT researchers in a recent publication.[1]
One of the constraints responsible for the low turnover of varieties is a lack of information among farmers on the performance of the newer products. Despite advancements in the development of new seeds and the retail infrastructure to reach farmers, neither the public nor the private sector is generating and disseminating information on the performance of different maize seed products across various agroecologies. Farmers therefore have choice overload but lack objective information on relative seed performance required to make informed seed choices across seasons and growing conditions.
CIMMYT conducted a field experiment to shed light on the potential influence of seed-product performance information on farmers’ seed choices. The study involved aggregating and packaging farmer reported yield data for some seed products and presenting this to randomly selected farmers at the point of sale to assess whether the new information would influence their choice of products. The study was conducted in Kirinyaga and Embu counties where, like many parts of Kenya, farmers have access to a diverse range of maize seed products from seed companies which promise benefits like higher yields and improved resilience but lack objective information on their performance which could support their choices, including when to switch and to what.
The study was conducted in March 2024, at the onset of the long rain season. The research team collaborated with 36 local agro-dealers in five towns and surveyed over one thousand farmers. Farmers were intercepted as they approached the agro-dealer outlets and briefed about the study. Upon consent, they were informed on the benefits of trying something new (experimenting with varieties) and were offered a voucher for one free bag of maize seed to encourage them to try a seed product new to them. They then were randomly assigned to two experimental groups: treatment and comparison. Participants in the treatment group were shown a chart containing product-specific yield data on maize hybrids grown in their counties (see the chart below). The chart contained farmer-reported yields from the previous year’s long rain season aggregated at two levels: county average yield and the average yield of the top 25% of farmers who realized the highest yields. The latter demonstrated the actual potential of a seed product. They were asked that, if they wished, they could choose the voucher product for experimentation from the list but they were not required to. Participants in the comparison group were offered placebo information that would not affect their seed choice: they were given some fun facts about Kenya and agriculture in Kenya. We assess the effect of the information on the choice of the bag of seed they were buying with the voucher to experiment with.
Table 1: Product-specific performance information on maize seed products in Kirinyaga March-August 2023 *actual product names have been removed for this blog*
Before they made any purchases, the customers were asked about which maize seed they intended to buy. After purchase, they were interviewed again to find out which maize seeds they bought and how they had used the voucher.
What we found
Majority of the treatment farmers had a very positive evaluation of the information they received, indicating that they found it relevant and useful when making seed choice. Specifically, over 90% of them said that the information was trustworthy and easy to understand while about 80% said that the information was easy to recall. Over 80% of them disagreed that the list of varieties was too long to comprehend, the information on varieties was similar and hard to differentiate and that it was hard for them to choose a variety from the list.
This positive evaluation of the information is also reflected in their seed choices. Pre-purchases (before they entered the agrodealer store), farmers who were exposed to the performance information showed increased certainty in their choices and a higher inclination towards products listed in the product performance data, particularly the top-performing varieties. While 5% of the comparison farmers indicated that they did not know what to buy with their vouchers, only 2% of the treatment farmers suffered the same uncertainty. Such farmers relied mostly on agro-dealers to recommend a product they could experiment with.
As shown by the bar chat below, only 7% of comparison group farmers desired to use their vouchers on (or had an effective demand for) products which were the top two in the product performance lists. This increased to 27% among the information group farmers, representing an increase of 286% in the demand of top performing products.
However, although our intervention relaxed an essential constraint (product performance information) and increased the demand for some seed products, the actual purchases were subject to other constraints, stock-outs key among them. As a result, both groups showed shifts from initially desired products in their actual purchases. Even so, the treatment group maintained a stronger alignment with the listed products, exhibiting a higher likelihood of purchasing top-performing products. Only 5% of farmers in comparison group used their vouchers to purchase products which were top two in the product performance lists. This increased to 13% among farmers in the treatment group, representing a 160% increase in the likelihood of purchasing the best performing products in the lists.
Reflections
Slow varietal turnover among maize farmers in E. Africa is a pervasive problem and there is no one solution to it. This research shows that information on product performance can be an effective approach in bringing to the attention of farmers newer, more adapted and better yielding seed products. Dissemination of such information can be incorporated in extension programs, shared at the point of sale, shared through SMSs and WhatsApp messages, displayed in posters fixed in public places, etc.
The findings offer clear recommendations for future investments in seed systems development. These include the implementation of new product testing regimes to ensure quality and objectivity of performance data, testing what other information would be useful to farmers – beyond yield data, exploring new marketing options to reach farmers more effectively, and considering additional approaches to empower farmers with the knowledge they need to make informed decisions thus leading to improved agricultural productivity, resilience, and livelihoods.
In conflict-ridden Sudan, Gadarif State in Eastern Sudan is the most important region for sorghum production, with about 5-6 million feddan (5.18-6.22 acres) cultivated on an annual basis on large scale farms equipped with agricultural machinery. However, like the country, the state is covered with vertisols, clay-rich soils that shrink and swell with changes in moisture content, that become waterlogged and cannot be properly cultivated during rainy season.
To address the issue, technical experts from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) are mapping areas affected by waterlogging in two localities, namely El Fashaga and El Nahal, to identify the most suitable lands to establish large drainage implementing sites integrated with improved crop varieties of sorghum. This work is part of CIMMYT’s Sustainable Agrifood Systems Approach for Sudan (SASAS) program, which works with farmers and herders to reduce their need for humanitarian assistance in conflict-affected Sudan.
“To address the issue of vertisols affected by water logging in Al Gadarif, the prominent agricultural region in Sudan, we used the map developed by ICRISAT in 2023 and consulted with local farmers to identify 100 hectares El Fashaga and El Nahal localities to improve drainage and avoid waterlogging,” said Gizaw Desta, senior scientist at ICRISAT.
Waterlogging is common on poorly drained soil or when heavy soil is compacted, preventing water from being drained away. This leaves no air spaces in the saturated soil, and plant roots literally drown. Waterlogging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death. In Gadarif state, 2.3 million hectares and 1.8 million hectares of vertisols are under high and moderate waterlogging conditions that impair crop production during the rainy season, leading to food insecurity if not reversed with appropriate agricultural practices.

“For years, my farm has been flooded by water during the rainy season, and I cannot cultivate sorghum as plants die of water suffocation”, said Ali Ahmed, a farmer from Al-Saeeda area of Al-Nahal locality who is affected by waterlogging. “Alternatively, we as farmers affected by waterlogging were forced to cultivate watermelon instead of our main staple food sorghum. This shift in the crops we cultivate is hardly affecting our income. I am glad that ICRISAT is working to establish drainage systems and address waterlogging within our lands.”
“At SASAS, we strive to ensure that farmers have access to fertile lands and other agricultural inputs. We work with our partners to address all problems facing farmers including waterlogging to help farmers continue producing their staple food and cash crops,” said Abdelrahman Kheir, SASAS chief of party in Sudan.

In the rural districts of Mbire and Murehwa in Zimbabwe, the CGIAR Agroecology Initiative (AE-I) has embarked on a comprehensive strategy that places farmers’ opinions at the heart of interventions to tackle the multifaceted challenges of agroecosystems. Recognizing challenges such as pest and disease outbreaks, periodic drought, inadequate grazing lands, and limited access to quality seeds and livestock breeds, the AE-I team has initiated a collaborative process involving various stakeholders to develop tailored agroecological solutions.
This integrated approach emphasizes active participation and cooperation among agricultural extension services, including the Department of Agricultural Technical and Extension Services of Zimbabwe (AGRITEX), food system actors (FSAs), and technology providers. These organizations have collaborated to form Agroecology Living Landscapes (ALLs) to identify, test, and iterate relevant innovations.
“This collaborative innovation and ongoing co-designing cycle empower local communities and fosters agricultural sustainability, positioning Zimbabwe as a model for agroecology transition,” said Vimbayi Chimonyo, CIMMYT scientist and crop modeler. “With these efforts, the AE-I is improving current agricultural practices but also building a foundation for future resilience in Zimbabwe’s rural districts.”
A representation diagram of the co-designing cycle.
To ensure a well-informed process, the AE-I research team began its efforts by identifying dominant value chains in the two districts. In Murehwa, these included horticulture, maize, groundnuts, and poultry; while in Mbire, sorghum, cotton, and livestock. Challenges noted included production constraints (availability of improved seed and labor), biophysical constraints (water availability, increased incidents of fall armyworm), economic (market access) and social (agency).
Next, the AE-I research team, and the ALLs conducted a series of surveys, focus group discussions, and key informant interviews to understand existing opportunities that might address the challenges and aid in strengthening the value chains. The AE-I team discovered opportunities related to addressing labor shortages and improving access to improved technologies.
As a result, the research team introduced appropriate scale machinery, suggested seed and livestock fairs to increase access to agroecological inputs, established a series of demonstration plots to showcase technologies that improve water use, and increased mitigation efforts for fall armyworm. After introducing machinery, seed and livestock fairs, and testing the technologies during the 2022/23 season, AE-I returned to ALL members to discuss the impact the activities had on their production systems and determine if any modifications were necessary.
Participants suggested increased visibility of the new technologies and methods, so the AE-I team enhanced demonstration plots and added 100 baby plots during the 2023-24 farming season.
Integrating adaptive testing and feedback yielded valuable information from farmers, providing a strong base for further adaptations in the 2023-24 farming season. This continuous engagement promoted adaptive and context-specific solutions within the AE-I, ensuring that interventions aligned with evolving community needs.
Technologies being tested
To achieve the visions of each ALL, context-specific technologies are being tested to ensure synergy across the identified value chains and collaboration among different food system actors.
Technology/Innovation
Description
Demo plots
2022-23: Twenty mother plots were established to compare the performance of cereal planted in, push-pull, and conventional practices on productivity, rainwater use efficiency, and pest biocontrol.
2023-24: Additional treatments, including biochar, live mulch, and traditional treatments, were introduced. One hundred eleven baby plots were established where farmers adapted mother protocols to suit their contexts.
Farmer Field Days
Conducted for the established demonstration plots in Mbire and Murehwa, these field days showcased the technologies to a broader audience and acted as an agent of evaluation and feedback for the AE-I team.
Mechanization
A service provider model was adopted to introduce appropriate scale machinery, addressing the drudgery associated with farming operations. Equipment provided included threshers, basin diggers, two-wheel tractors, rippers, mowers, chopper grinders, and balers. Training on operation, repair, and maintenance was also provided.
Capacity building
Yearly work plans, co-designed by ALLs, identification of training needs, gaps, and priorities. Facilitated by AGRITEX, these trainings equip farmers with knowledge essential to facilitate agroecology transition and fulfil ALL visions.
Monitoring and evaluation is a valuable component in the co-designing process where the AE-I establishes a feedback loop, engaging farmers and government stakeholders in participatory monitoring and evaluation. This ongoing exercise analyzes various indicators across different experimental treatments, providing valuable insights into the effectiveness and suitability of these approaches within the agricultural context. This continuous analysis leads to further co-designing of tailored solutions for facilitating the agroecology transition.
Farmers and stakeholders from AGRITEX welcomed and appreciated the co-designing process, as they felt empowered by the entire process. They expressed how it gives them ownership of the technologies being implemented through the AE-I project.
The success of the AE-I in the Mbire and Murehwa districts hinges on active participation and collaboration among FSAs. By continuously evaluating and integrating feedback on innovations and addressing challenges through context-specific interventions, the initiative is paving the way for adopting agroecological practices in farming, enhancing the resilience of local food systems.

Florence Mutize’s thriving fields of maize, in Bindura, a small town in Mashonaland Central region of Zimbabwe, serve as living proof of the successes of Conservation Agriculture (CA), a sustainable cropping system that helps reverse soil degradation, augment soil health, increase crop yields, and reduce labor requirements while helping farmers adapt to climate change. The seeds of her hard work are paying off, empowering her family through education and ensuring that a nutritious meal is always within reach.
“I have been dedicated to these CA trials since 2004, starting on a small plot,” said Mutize. “Now, with years of experience and adaptation to changing climates, I’ve seen my yields increase significantly, harvesting up to a tonne of maize on a 30 by 30m plot using direct seeding and ripping techniques together with crop residue to cover the soil and rotating maize with soybean.”
Mutize is one of many mother trial host farmers implementing CA principles through the CGIAR Ukama Ustawi regional initiative in Bindura. A mother trial is a research approach involving testing and validating a suite of climate-smart agriculture technologies to identify the best-performing ones which can then be adopted on a larger scale.
Nestled in the Mazowe valley, Bindura experiences a subtropical climate characterized by hot, dry summers and mild, wet winters, ideal for agricultural production. But the extremes of the changing climate, like imminent dry spells and El Niño-induced threats, are endangering local farmers. Yet, smallholder farmers like Mutize have weathered the extremes and continued conducting mother trials, supported by the agriculture extension officers of the Agricultural and Rural Development Advisory Services (ARDAS) Department of the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development.
“Where I once harvested only five bags of maize, rotating maize with soybeans now yields 40 bags of maize and 10 bags of soybeans,” Mutize proudly shares.
The UU-supported CA program also extends to farmers in Shamva, like Elphas Chinyanga, another mother trial implementer since 2004.

“From experimenting with various fertilization methods to introducing mechanized options like ripping and direct seeding, these trials have continuously evolved,” said Chinyanga. “Learning from past experiences, we have gotten much more benefits and we have incorporated these practices into other fields beyond the trial area. I am leaving this legacy to my children to follow through and reap the rewards.”
Learning has been a crucial element in the dissemination of CA technologies, with CIMMYT implementing refresher training together with ARDAS officers to ensure that farmers continue to learn CA principles. As learning is a progressive cycle, it is important to package knowledge in a way that fits into current training and capacity development processes.

This process could also be labelled as “scaling deep” as it encourages farmers to move away from conventional agriculture technologies. Reciprocally, scientists have been learning from the experiences of farmers on the ground to understand what works and what needs improvement.
Inspired by the successes of his peers in Shamva, Hendrixious Zvomarima joined the program as a host farmer and saw a significant increase in yields and efficiency on his land.
“For three years, I have devoted time to learn and practice what other farmers like Elphas Chinyanga were practicing. It has been 14 years since joining, and this has been the best decision I have made as it has improved my yields while boosting my family’s food basket,” said Zvomarima.
The longevity and success of the initiative can be attributed to committed farmers like Mutize, Chinyanga, and Zvomarima, who have been part of the program since 2004 and are still executing the trials. Farmer commitment, progressive learning, and cultivating team spirit have been the success factors in implementing these trials. CIMMYT’s long-term advocacy and learning from the farmers has been key to a more sustainable, resilient, and empowered farming community.
“Achieving food security by mid-century means producing at least 50 percent more food,” said U.S. Special Envoy for Global Food Security, Cary Fowler, citing a world population expected to reach 9.8 billion and suffering the dire effects of violent conflicts, rising heat, increased migration, and dramatic reductions in land and water resources and biodiversity. “Food systems need to be more sustainable, nutritious, and equitable.”
CIMMYT’s 2030 Strategy aims to build a diverse coalition of partners to lead the sustainable transformation of agrifood systems. This approach addresses factors influencing global development, plant health, food production, and the environment. At DialogueNEXT, CIMMYT and its network of partners showcased successful examples and promising directions for bolstering agricultural science and food security, focusing on poverty reduction, nutrition, and practical solutions for farmers.
Without healthy crops or soils, there is no food
CIMMYT’s MasAgro program in Mexico has enhanced farmer resilience by introducing high-yielding crop varieties, novel agricultural practices, and income-generation activities. Mexican farmer Diodora Petra Castillo Fajas shared how CIMMYT interventions have benefitted her family. “Our ancestors taught us to burn the stover, degrading our soils. CIMMYT introduced Conservation Agriculture, which maintains the stover and traps more humidity in the soil, yielding more crops with better nutritional properties,” she explained.
CIMMYT and African partners, in conjunction with USAID’s Feed the Future, have begun applying the MasAgro [1] model in sub-Saharan Africa through the Feed the Future Accelerated Innovation Delivery Initiative (AID-I), where as much as 80 percent of cultivated soils are poor, little or no fertilizer is applied, rainfed maize is the most widespread crop, many households lack balanced diets, and erratic rainfall and high temperatures require different approaches to agriculture and food systems.
The Food and Agriculture Organization of the United Nations (FAO) and CIMMYT are partnering to carry out the Vision for Adapted Crops and Soils (VACS) movement in Africa and Central America. This essential movement for transforming food systems endorsed by the G7 focuses on crop improvement and soil health. VACS will invest in improving and spreading 60 indigenous “opportunity” crops—such as sorghum, millet, groundnut, pigeon pea, and yams, many of which have been grown primarily by women—to enrich soils and human diets together with the VACS Implementers’ Group, Champions, and Communities of Practice.
The MasAgro methodology has been fundamental in shaping the Feed the Future Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, an effort between government agencies, private, and public partners, including CGIAR. AID-I provides farmers with greater access to markets and extension services for improved seeds and crop varieties. Access to these services reduces the risk to climate and socioeconomic shocks and improves food security, economic livelihoods, and overall community resilience and prosperity.
Healthy soils are critical for crop health, but crops must also contain the necessary genetic traits to withstand extreme weather, provide nourishment, and be marketable. CIMMYT holds the largest maize and wheat gene bank, supported by the Crop Trust, offering untapped genetic material to develop more resilient varieties from these main cereal grains and other indigenous crops. Through the development of hardier and more adaptable varieties, CIMMYT and its partners commit to implementing stronger delivery systems to get improved seeds for more farmers. This approach prioritizes biodiversity conservation and addresses major drivers of instability: extreme weather, poverty, and hunger.
Food systems must be inclusive to combat systemic inequities
Successful projects and movements such as MasAgro, VACS, and AID-I are transforming the agricultural landscape across the Global South. But the urgent response required to reduce inequities and the needed investment to produce more nutritious food with greater access to cutting-edge technologies demands inclusive policies and frameworks like CIMMYT’s 2030 Strategy.
“In Latin America and throughout the world, there is still a huge gap between the access of information and technology,” said Secretary of Agriculture and Livestock of Honduras, Laura Elena Suazo Torres. “Civil society and the public and private sectors cannot have a sustainable impact if they work opposite to each other.”
Ismahane Elouafi, CGIAR executive managing director, emphasized that agriculture does not face, “a lack of innovative science and technology, but we’re not connecting the dots.” CIMMYT offers a pathway to bring together a system of partners from various fields—agriculture, genetic resources, crop breeding, and social sciences, among others—to address the many interlinked issues affecting food systems, helping to bring agricultural innovations closer to farmers and various disciplines to solve world hunger.
While healthy soils and crops are key to improved harvests, ensuring safe and nutritious food production is critical to alleviating hunger and inequities in food access. CIMMYT engages with private sector stakeholders such as Bimbo, GRUMA, Ingredion, Syngenta, Grupo Trimex, PepsiCo, and Heineken, to mention a few, to “link science, technology, and producers,” and ensure strong food systems, from the soils to the air and water, to transform vital cereals into safe foods to consume, like fortified bread and tortillas.
Reduced digital gaps can facilitate knowledge-sharing to scale-out improved agricultural practices like intercropping. The Rockefeller Foundation and CIMMYT have “embraced the complexity of diversity,” as mentioned by Roy Steiner, senior vice-president, through investments in intercropping, a crop system that involves growing two or more crops simultaneously and increases yields, diversifies diets, and provides economic resilience. CIMMYT has championed these systems in Mexico, containing multiple indicators of success from MasAgro.
Today, CIMMYT collaborates with CGIAR and Total LandCare to train farmers in southern and eastern Africa on the intercrop system with maize and legumes i.e., cowpea, soybean, and jack bean. CIMMYT also works with WorldVeg, a non-profit organization dedicated to vegetable research and development, to promote intercropping in vegetable farming to ensure efficient and safe production and connect vegetable farmers to markets, giving them more sources for greater financial security.
Conflict aggravates inequities and instability. CIMMYT leads the Feed the Future Sustainable Agrifood Systems Approach for Sudan (SASAS) which aims to deliver latest knowledge and technology to small scale producers to increase agricultural productivity, strengthen local and regional value chains, and enhance community resilience in war-torn countries like Sudan. CIMMYT has developed a strong partnership funded by USAID with ADRA, CIP, CRS, ICRISAT, IFDC, IFPRI, ILRI, Mercy Corps, Near East Foundation, Samaritan’s Purse, Syngenta Foundation, VSF, and WorldVeg, to devise solutions for Sudanese farmers. SASAS has already unlocked the potential of several well-suited vegetables and fruits like potatoes, okra, and tomatoes. These crops not only offer promising yields through improved seeds, but they encourage agricultural cooperatives, which promote income-generation activities, gender-inclusive practices, and greater access to diverse foods that bolster family nutrition. SASAS also champions livestock health providing food producers with additional sources of economic resilience.
National governments play a critical role in ensuring that vulnerable populations are included in global approaches to strengthen food systems. Mexico’s Secretary of Agriculture, Victor Villalobos, shared examples of how government intervention and political will through people-centered policies provides greater direct investment to agriculture and reduces poverty, increasing shared prosperity and peace. “Advances must help to reduce gaps in development.” Greater access to improved agricultural practices and digital innovation maintains the field relevant for farmers and safeguards food security for society at large. Apart from Mexico, key government representatives from Bangladesh, Brazil, Honduras, India, and Vietnam reaffirmed their commitment to CIMMYT’s work.
Alice Ruhweza, senior director at the World Wildlife Fund for Nature, and Maria Emilia Macor, an Argentinian farmer, agreed that food systems must adopt a holistic approach. Ruhweza called it, “The great food puzzle, which means that one size does not fit all. We must integrate education and infrastructure into strengthening food systems and development.” Macor added, “The field must be strengthened to include everyone. We all contribute to producing more food.”
Generating solutions, together
In his closing address, which took place on World Population Day 2024, CIMMYT Director General Bram Govaerts thanked the World Food Prize for holding DialogueNEXT in Mexico and stressed the need for all partners to evolve, while aligning capabilities. “We have already passed several tipping points and emergency measures are needed to avert a global catastrophe,” he said. “Agrifood systems must adapt, and science has to generate solutions.”
Through its network of research centers, governments, private food producers, universities, and farmers, CIMMYT uses a multidisciplinary approach to ensure healthier crops, safe and nutritious food, and the dissemination of essential innovations for farmers. “CIMMYT cannot achieve these goals alone. We believe that successful cooperation is guided by facts and data and rooted in shared values, long-term commitment, and collective action. CIMMYT’s 2030 Strategy goes beyond transactional partnership and aims to build better partnerships through deeper and more impactful relationships. I invite you to partner with us to expand this collective effort together,” concluded Govaerts.
[1] Leveraging CIMMYT leadership, science, and partnerships and the funding and research capacity of Mexico’s Agriculture Ministry (SADER) during 2010-21, the program known as “MasAgro” helped over 300,000 participating farmers to adopt improved maize and wheat varieties and resource-conserving practices on more than 1 million hectares of farmland in 30 states of Mexico.
While maize is the primary staple food crop in Zambia, its productivity on farmers’ fields reaches on average only about 20 percent of what it could achieve with good agronomic practices. Some reasons for this inefficiency are use of traditional varieties, low fertilizer use, and ineffective weed and pest control.
Closing the gap between potential and realized yields would have major benefits for farmers in Zambia, both in terms of income and food security at the household and national levels. One possibility to increase maize productivity is by increasing crop diversity through the inclusion of legumes in maize-based farming systems. This could be done through intercropping, growing legumes in the rows between maize plants, or crop rotations and alternating maize and legumes in the same field from season to season.
CIMMYT scientists, along with collaborators from the Zambia Agriculture Research Institute (ZARI) and the University of Zambia’s School of Agricultural Science, set out to determine which cropping systems might lead to increased productivity for maize farmers in Zambia and their results were published in the journal Field Crops Research.
“There is great potential in Zambia to increase yields to help ensure food security,” said Mulundu Mwila, PhD candidate and scientist at ZARI. “We wanted to determine the cropping systems that offered the most benefits.”
Setting up the study
For this research, ZARI and CIMMYT scientists established maize-based cropping systems trials, comprising maize monocropping, and maize-legume rotations and intercrops under both ‘conventional’ tillage, and Conservation Agriculture, across 40 farms in a variety of agroecological zones in Zambia. The team also conducted household surveys in the same communities hosting the on-farm trials to determine the share of households with enough cultivated land to benefit from the tested cropping systems.
Researchers found that the tested cropping systems produced more maize per hectare compared to non-trial host farms in the same region. The greatest positive effect uncovered was that maize-legume rotations in Zambia’s Eastern Province had the potential to increase maize yield by 1 to 2 tons per hectare, per growing season. “The Eastern Province trials showed better results because of stable and adequate rainfall amounts and distribution and because of using groundnut as a rotation crop,” said Mwila.
Researchers attributed the small effect of legumes on maize yield in the Southern Province to low levels of biomass production and nitrogen fixation, due to low and erratic rainfall, and to low residue incorporation because of livestock grazing. Conversely, the small effect of legumes on maize yield in the Northern Province might be attributed to the high rainfall amount in the region, leading to high rates of leaching of residual nitrogen during the growing season as well as the use of common beans as the preceding crop.
Finding the right amount of land
With evidence showing the potential benefits of maize-legume rotations, the availability of land is a constraint for small farms across sub-Saharan Africa, thus it is important to quantify the land area needed for farmers to implement maize-legume rotations.
“Our findings match prior research showing the benefits of maize-legume rotations in Eastern Zambia” said Silva. “However, implementing maize-legume rotations remains a challenge for many smallholders due to small farm sizes.”
Nearly 35, 50, and 70% of the surveyed farms in the Northern, Eastern, and Southern Provinces, respectively, had enough land to achieve the same level of maize production obtained on their farm with the yields of the maize-legume rotations tested in the on-farm trials. “With our findings showing increased maize yields, and our efforts to determine the amount of land needed for food and nutrition security at household level, the next steps can be to facilitate methods to disseminate this information to policy makers and to farmers that have enough land area to benefit from diversified cropping systems,” said Silva.
For farmers with not enough land to reap the benefits of maize-legume rotations, intercropping legumes within the maize has shown promising results. The researchers also call for further research to specify the contributing factors to small farms not seeing benefits from maize-legume rotations.
Chris Ojiewo, from CIMMYT, emphasizes the urgent need for African farmers to produce more food within restricted areas to accommodate the continent’s growing population. He advocates for increasing crop productivity by developing resilient varieties and advanced production systems that can thrive in intensified and drought-prone conditions. Ojiewo suggests boosting maize yields from one ton per hectare to higher levels through innovative agricultural practices, highlighting CIMMYT’s role in addressing food security challenges exacerbated by climate change.

Farmers interact with soils daily, supporting the entire food system. Empowering them with tools for research and scalable learning initiatives is crucial.
Speaking as a panelist at the 2024 Africa Fertilizer and Soil Health (AFSH) summit, Paswel Marenya, CIMMYT senior scientist, emphasized the need to enhance farmers’ capacities to effectively utilize digital tools.
“Digital tools do not inherently lead to impactful changes unless they enhance farmers’ capabilities in managing soil health,” said Marenya. “The potential of a digital tool should enable farmers to shorten the cycle from receiving information to applying new techniques.”

Simple, easy to use tools
One promising solution is the development of user-friendly platforms that synthesize essential information from cutting-edge research into practical tools.
“In partnership with IFDC, CIMMYT is currently collaborating to develop an interface that synthesizes essential information into a user-friendly digital platform. This interface would be complemented by tools that allow for on-site testing,” said Marenya.
“CIMMYT aims to design digital tools that not only improve access to information but enhance the farmers’ ability to learn, innovate, and adapt. This approach promises real progress beyond more recommendations,” said Marenya.
This sentiment was echoed by Leigh Winowiecki, soil and land health global research lead at CIFOR-ICRAF, who discussed advancements in soil health monitoring and highlighted the Land Degradation Surveillance Framework (LDSF) which collects data on various indicators of soil health.

Addressing the forum as the keynote speaker for the side event titled, “Digging deeper: Advancement in soil health monitoring for sustainable food systems and climate resilience,” Winowiecki showcased the global implementation and impact of the framework, noting its implementation in 40 countries.
“This framework is a field-based method that collects data on various indicators of soil health, land degradation, and vegetation diversity across landscapes,” Winowiecki said.
The findings from the framework guide practical interventions to mitigate soil erosion and influence policy.
Annie Wakanyi, director of partnerships & business development at One Acre Fund, highlighted how they prioritize farmers by providing high-quality inputs on credit, ensuring they are distributed near their farm fields, and offering training on usage, as well as assisting farmers in accessing markets for the surplus they produce.

Professor Nalivata of Lilongwe University of Agriculture and Natural Resources emphasized the importance of addressing soil erosion to achieve soil health in Africa using Malawi as a case study. He discussed policy implementation on fertilizer, promoting climate-smart agricultural practices and research as strategies implemented to address soil degradation in Malawi, calling for more initiatives like incentives for farmers and building human capacity.
“This can be achieved if we maintain a collaborative approach involving government, academia, the private sector, and donor communities to transform soil health and improve livelihoods,” said Nalivata.

Improving soil health is critical to sustainable agriculture, and for addressing climate change, tackling environmental challenges, and enhancing food security. Through projects by CIMMYT and partners, potential scalable solutions are under development, but additional work is still required.
“To effectively scale up soil health initiatives, we need to prioritize investments and establish a framework that maximizes returns,” said Bram Govaerts, CIMMYT director general, during the 2024 Africa Fertilizer and Soil Health (AFSH) Summit in Nairobi, Kenya. “It is crucial to use simple, quantifiable indicators for systematic assessments and decision-making, and to broaden these indicators to foster investment from public, private, and civil actors.”
As a keynote speaker in the “Strategies to Foster Africa’s Resilience to the Global Fertilizer Crisis” parallel session, Govaerts highlighted the intertwined challenges of soil health and fertilizer accessibility. “95% of our food comes from the soil, yet in 14 countries the cost of fertilizer has more than doubled. Fertilizers contribute to 2% of global greenhouse gas emissions and are often mismanaged—overused in some regions and underutilized in others.”
The transition to a more sustainable and climate-resilient approach to soil health and fertilizer use requires a comprehensive structure that considers broader aspects of agricultural sustainability. “To enhance soil health effectively, a clear framework is necessary that includes investment prioritization, integrated soil management, extension and advisory services, and the utilization of data and technology,” Govaerts added.
This recommended framework included identifying and prioritizing investment opportunities, balancing organic and inorganic inputs, strengthening extension systems, and leveraging technology to provide farmers real-time advice.
One practical example of effective soil health management in practice is CIMMYT’s Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub. The project helps farmers cope with high fuel and fertilizer prices by providing them with innovative tools and information to manage cost and supply disruptions. This addresses systemic weaknesses in agriculture by accelerating market-based delivery of improved seed, fertilizer, and critical information to farmers.
“Under AID-I, rapid soil testing has been prioritized. Collaborating with the International Fertilizer Development Center (IFDC) and mobile soil labs like those in Zambia exemplify innovative data point collection strategies,” said Govaerts.
During the panel discussion, Anne Muriuki, principal research officer at the Kenya Agricultural and Livestock Research Organization (KALRO) highlighted the key challenges that African countries face in accessing fertilizers during global crises and the impact on agricultural productivity. “Farmers face scarcity and high costs, leading to reduced yields and increased reliance on unsustainable fertilizers. These issues not only reduce agricultural productivity, but they also aggravate food insecurity and economic instability.”
David Nielsen, a former World Bank official, stressed the importance of having site-specific soil information and investing in human capital and educational institutions to increase soil science expertise and improve the availability of site-specific information. “These two issues should be high priorities. They are crucial, especially when fertilizer access is limited, but they remain vital even with adequate fertilizer supply.”
Douglas Kerr, vice president of business development at the IFDC discussed how governments, international non-governmental organizations (NGOs), and the private sector can collaborate to ensure continuous access to fertilizer during a global crisis. The Sustain African Program was an example of IFDC’s role in gathering market information and developing a concept that has since been integrated into ongoing operations. “In a nutshell, multi-stakeholder collaboration needs to be open, transparent, supportive, and unified.”
Charlotte Hebebrand, director of communications and public affairs at the International Food Policy Research Institute (IFPRI), emphasized the need to increase fertilizer production within Africa, improve access to markets, and address response constraints to reduce shocks. “A major focus is on repurposing subsidies. It is sensitive but critical to determine the most efficient way to support farmers and promote soil health.”
Mehti Filali, senior vice president of OCP in West Africa, highlighted successful case studies from Ethiopia and Nigeria, where domestic initiatives and regional cooperation have resulted in significant agricultural growth. “Ethiopia has doubled crop production and created tailored fertilizer formulas, while Nigeria’s initiative has consolidated fertilizer procurement, created jobs, and saved US $250 million in foreign exchange. OCP’s contribution, though modest, has been critical, marked by significant milestones such as soil testing and the development of blending units.”
As Africa continues to face these challenges, the response must be dynamic, drawing on both local knowledge and scientific data. Robust data governance is essential for integrating soil health into market-driven decision-making, promoting crop diversification, and integrating organic and inorganic inputs for sustainable agriculture. “Let us remember the importance of integrating soil fertility management in a step-by-step manner, prioritizing action tailored to specific locations and conditions. Sophisticated extension systems, backed up by robust data, are crucial,” Govaerts concluded.
With 96% of its population engaged in farming and crop production, residents of the province of Niassa in the northern part of Mozambique rely heavily on agriculture for both their own nutritional needs and household income.
Famers in Niassa face many challenges in achieving successful agricultural development, including a 60% yield gap between male head of household farms and female led farms and while improved crop varieties are available, their rate of adoption is uneven across the province.
Implemented by CIMMYT in partnership with key collaborators and supported by Irish Aid, the Transformative Dryland Crops Project aims to enhance food security and boost incomes for more than 14,000 farm families in Niassa.

Speaking at the launch meeting, Niassa’s Secretary of State, Lina Maria da Silva Portugal said, “This project focuses on leveraging technology and innovative approaches to bolster resilience and sustainability which will benefit all of Niassa.”
The Transformative Dryland Crops Project will focus on crops known for their drought tolerance, such as pigeon peas, groundnuts, common beans, and soybeans. By adopting a ‘hub-model’ approach, the project will enhance learning and technology dissemination, facilitating collaboration among farmers, farmer organizations, service providers, buyers, and processors. This collaborative effort will ensure the effective implementation of the project and maximize its impact on the ground.
“Through collaborative efforts with local stakeholders, we aim to narrow the gender yield gap, increase adoption rates of improved crop varieties, and enhance overall agricultural productivity, said Irish AID Ambassador, Adrian Fitzgerald.
Governor of Lichinga, Judite Massengele, Niassa’s capitol, said, “The launch of this project marks a significant milestone in the journey towards enhancing food security and improving livelihoods here in Niassa.”

Transformative changes
Besides increased agricultural productivity, enhanced food security, and income generation, the Transformative Dryland Crops Project promotes gender equity, increases resilience to climate shocks, implements sustainable resource management, builds capacity among farmers and extension agents and facilitates inclusive market systems.
“The Transformative Dryland Crops Project will impact many different parts of the agricultural system of Niassa,” said Moses Siambi, CIMMYT Africa regional director. “The key part of our implementation plan is the knowledge that all these systems and stakeholders are interconnected and any intervention in one of part of the system must account for its effects on the entire system in order to be sustainable.”
As the world grapples with climate change, resilient crops such as millets play an increasingly important role. Their ability to thrive in low soil fertility and limited moisture levels makes them ideal for Africa’s changing climate. However, despite their potential, it remains largely untapped.
In an initiative to address the untapped potential and the growing challenges associated with the cultivation of pearl and finger millets in Africa, a high-profile discussion convened experts from various fields. This session, part of a workshop titled “Bottlenecks to Expansion of Pearl and Finger Millets in Africa,” organized by the Bill & Melinda Gates Foundation in collaboration with the Senegalese Institute of Agricultural Research (ISRA) and CIMMYT, aimed to identify and prioritize key bottlenecks in crop improvement.

Significance of the International Year of Millets
The United Nations General Assembly declared 2023 the International Year of Millets to raise awareness of and direct policy attention to the nutritional and health benefits of millets and their suitability for cultivation under adverse and changing climatic conditions. The program highlighted the critical need to promote sustainable agriculture and enhance food security by adopting climate-resilient crops like millets, which play an important role in mitigating the effect of climate change, due to their adaptability to adverse and changing climatic conditions.
“We have been actively engaged in gathering input and support from all over the world, not just from Africa and Asia but also from regions like Latin America and Eastern Europe,” said Makiko Taguchi of the Food and Agriculture Organization (FAO). “This year has seen a surge in interest and collaboration in the millet community and we are excited about the possibilities that lie ahead,” she added.

National strategies to enhance millet production
In an effort to ensure food security and achieve production goals over the next five years in Senegal, a strategic plan encompassing various key initiatives will be implemented to meet the demands of millets.
Hamidou Diallo, from the Ministry of Agriculture, Rural Equipment, and Food Sovereignty of Senegal (MAERSA), summarized the strategy. First, is a focus on enhancing production and productivity. Second, the plan calls for the use of high-quality seeds and collaboration with ISRA to provide foundational seeds. Third, aiming to equip producers with the necessary tools and equipment. Last, the plan seeks to increase the overall cultivated area of millets.
“We align ourselves with the needs of the local community. By doing this, it ensures that the initiatives undertaken are not only impactful but also resonate with the agricultural landscape and the needs of the communities served,” said Diallo.

Innovative initiatives for the Dryland Crops Program
Kevin Pixley, director of the Dryland Crops Program (DCP) and Wheat Program director a.i. at CIMMYT, highlighted four initiatives in which the program is involved. One is the establishment of the Africa Dryland Crops Improvement Network, comprising national program scientists and led by the steering committee from Eastern and Southern Africa (ESA) and Western and Central Africa (WCA). Their mandate is examining investments in capacity development and infrastructure and shape breeding programs. Second, a legumes mining project at Colorado State University, focusing on genetic diversity and using big data tools to identify resilient traits. Third, working on gene editing projects such as reducing rancidity in pearl millets in countries that are open to these technologies. Last, the Vision for Adapted Crops and Soils (VACS) project, that will include millets as a prioritized crop. These initiatives are crucial for creating pathways to improve farmers’ livelihoods and popularize millets.
“Creating an effective pathway is critical to these approaches. We need to find innovative ways to reach more farmers with options to improve their livelihood and popularize millets across different market segments,” said Pixley.

CIMMYT’s program on Dryland Crops is at the forefront to improving breeding and seed systems, with the aim to improve the livelihoods of small-scale producers and consumers of these crops in sub-Saharan Africa.
Aware of the changing needs of the global community, CIMMYT has begun on a journey to advance research and broaden its impact by implementing the Dryland Crops Program. This approach is based CIMMYT’s 2030 Strategy, which has the potential to shape the future of agriculture as a catalyst of climate resilience, sustainable and inclusive agricultural development, and food and nutrition security.
The program is critical in promoting climate resilience, sustainable agricultural practices, and food and nutrition security in sub-Saharan Africa. CIMMYT is working on dryland crops like millets and legumes, which have untapped potential for contributing to food security, particularly in climate-vulnerable regions.
Research and innovative labs
Geoff Morris from Colorado State University shared insights on the recently concluded United States Agency for International Development (USAID) Innovation Lab on Sorghum and Millets. This activity spanned the entire value chain from trait discovery to breeding program support to the development of value-added products. The most successful projects, in his opinion, were those led by African-based scientists.
“It is essential for Africa scientists to be in the driver sear to ensure that research agenda aligns with their needs,” he said. “There is a gap in knowledge not about what we know here but about what U.S. researchers know about supporting African breeders. It’s crucial for researchers to define the needs to guide effective collaborations,” said Morris.
Pioneering role in millet sector growth
The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) has contributed significantly to driving growth in the millet sector, including innovation generation and knowledge sharing. Damaris Odeny, ICRISAT India, highlighted the organization’s contributions particularly in the agri-business incubation platform. The platform serves as a bridge, identifying suitable technologies to specific regions and supporting local entrepreneurs in deploying these technologies to reach smallholder farmers. While the model has been successful in India, its adoption in Africa has been slower, owing to regional differences and varying levels of investments.

The Feed the Future Innovation Lab for Crop Improvement, managed by USAID and Cornell University efforts in fostering regional collaborations funds a center for innovations across regions, fostering regional collaborations that are critical for sharing knowledge and resources, benefiting not only regions within Africa but also further afield.
“Moving forward, we should align these initiatives and identify synergies to maximize their impact. This approach will encourage greater engagement and the adoption of innovative solutions at the local level,” said Odeny.
The path forward for millets in Africa and beyond is not only promising but essential for addressing issues of food security, climate resilience, and sustainable development. This can be accomplished by aligning these initiatives with global sustainability goals and focusing on innovative, collaborative efforts.
Changing the narrative through communication
Turning to the power of communication, Douglas Gayeton, co-founder of The Lexicon emphasized the role of effective messaging in changing people’s perceptions of millets.
“When consumers understand what they are purchasing and how it aligns with their values, they can make informed decisions that benefit the entire food system,” said Gayeton.
He also underscored the importance of changing the narrative around millets. He emphasized the importance of shifting away from terms like ‘neglected’ and ‘orphaned’ crops to more positive empowering language that resonates with consumers and policy makers.
“In order to change the food system, we must provide consumers with information at the point of purchase that applies to their values. By linking that benefit to consumer values, this approach has the potential to significantly expand millet markets,” said Gayeton.

The discussions highlighted the valuable lessons to be learned from the efforts to enhance millet utilization in Africa and other regions. The collaboration across various sectors, from government to research institutions and the private sector, highlights the multifaceted approach in addressing the challenges facing millet cultivation and utilization. Recognizing the significance of local engagement and the empowerment of local scientists underscores a crucial lesson: solutions need to be tailored to the specific context, utilize local knowledge, and address local needs to ensure sustainability. In addition, the significant impact of communication in reshaping perceptions about millets demonstrates the importance of storytelling in shaping consumer behavior and policy.
In a world grappling with regional conflicts, climate change, and fragile food systems, the G7 emphasized sustainable agriculture and food security as essential for global stability in a recent communique. CIMMYT supports this vision through the Vision for Adapted Crops and Soils (VACS) initiative, which the G7 recognized as essential in transforming food systems. VACS aims to boost agricultural productivity with climate-resilient crops and healthy soils.
“With our partners, we will work on concrete and ambitious actions to achieve long-term sustainable development, strong environmental, social, and governance standards, and shared prosperity worldwide,” stated the G7 communique.
Fortifying indigenous crops
The G7 statement highlights the importance of dryland crops for sub-Saharan Africa, particularly ancestral grains and peas in securing nutrient-rich diets. CIMMYT, with over 75 partners such as WorldVeg and the Kenya Agricultural and Livestock Research Organization (KALRO), implements the VACS Quick Wins Seed Systems Project across west, east, and south Africa. The project promotes adoption of dryland grains and legumes, helps smallholders obtain climate-resilient seeds, and connects them with markets and agri-services. CIMMYT and its partners recently published a report which identifies the required training in crop breeding to support project implementation across the continent.
“VACS is working to improve the livelihoods of smallholders,” said Bram Govaerts, CIMMYT’s director general. “CIMMYT is implementing VACS focused on crop breeding, seed systems, partnerships, and capacity development. These areas protect our most important grains from further fragility.”
CIMMYT is also leading genetic research by predicting novel traits necessary for future crop varieties. A 2023 study published in Molecular Plant by CIMMYT scientists identified essential traits in six crops: sorghum, pearl millet, groundnut, cowpea, maize, and common bean. These characteristics could improve global food and nutrition security. High-yielding traits in legumes are being scaled up for delivery by CIMMYT and Afriseed through the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, targeting over 35,000 smallholders in Zambia during 2023-2024.

Capacity development through sustained global partnerships
Several G7 members, including the United States, support CIMMYT’s efforts with VACS. A key component of the initiative is capacity building for local researchers and practitioners. A recent initiative aims to train African breeding programs and research professionals, creating a cohort of VACS Fellows to strengthen local and regional food systems. In Guatemala, InnovaHubs, through partnership with CGIAR, Mexico, and Norway, brings farmers closer to markets, technologies, and high-quality seeds.
Strategy for the future
With over 130 countries depending on food imports and over 1.3 billion people considered food insecure, CIMMYT’s 2030 Strategy provides a comprehensive plan forward for agrifood systems through innovative research and partnerships. “Our partners provide the local knowledge and expertise to ensure our research has an impact on smallholder communities. Only through close collaboration with local actors can we transform global food production to become more inclusive and sustainable,” said Govaerts. “We stand ready to support G7 goals for shared prosperity.”

While healthy soils and crops are key to improved harvests, ensuring safe and nutritious food production is critical to alleviating hunger and inequities in food access. CIMMYT engages with private sector stakeholders such as Bimbo, GRUMA, Ingredion, Syngenta, Grupo Trimex, PepsiCo, and Heineken, to mention a few, to “link science, technology, and producers,” and ensure strong food systems, from the soils to the air and water, to transform vital cereals into safe foods to consume, like fortified bread and tortillas.
National governments play a critical role in ensuring that vulnerable populations are included in global approaches to strengthen food systems. Mexico’s Secretary of Agriculture, Victor Villalobos, shared examples of how government intervention and political will through people-centered policies provides greater direct investment to agriculture and reduces poverty, increasing shared prosperity and peace. “Advances must help to reduce gaps in development.” Greater access to improved agricultural practices and digital innovation maintains the field relevant for farmers and safeguards food security for society at large. Apart from Mexico, key government representatives from Bangladesh, Brazil, Honduras, India, and Vietnam reaffirmed their commitment to CIMMYT’s work.
