Rajendra Kathariya, a 41-year-old resident of Joshipur-2 in Kailali district, far-west of Kathmandu, has transformed his life and that of his family of five through commercial agriculture. Despite many challenges, Rajendra has remained committed to achieving financial sustainability through enhanced farming practices. Over the last two years, his partnership with Nepal Seed and Fertilizer (NSAF) and CIMMYT, in collaboration with Nisrau Multipurpose Cooperative, a partner cooperative of NSAF, has been instrumental in his success.
Moving from traditional to modern farming
Previously, Rajendra cultivated cereal crops using traditional methods which often led to food crises for his family. However, he has now shifted to cultivating various crops throughout the year using modern farming techniques on his 1.02 ha of land and an additional 2.71 ha which he has leased.
“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said.
Remarkable achievements in crop production
Last year, Rajendra cultivated rice on 3.72 ha, yielding 8.8 metric tons (t) worth NPR 250,000 (US $1,880.71). Similarly, he sold 3.8t of spring maize from 1.35 ha, earning NPR 110,000 (US $827.51). This year, he expanded maize cultivation to 2.03 ha, with an expected income of NPR 200,000 (US $1,504.57). His potato crop yielded 5.5t worth NPR 125,000 (US $940.35), with an additional 5.5t stored for future sale.
In addition to crops, Rajendra has established a pig farm, earning NPR 400,000 (US $3,009.13) in 2023 from selling pigs. He received a feed-making machine for pigs from NSAF, under its support to agribusiness Micro, Small and Medium Enterprises (MSMEs).
Embracing modern technology and techniques
Rajendra uses both organic and chemical fertilizers and follows improved farming techniques such as hybrid seeds, line sowing, and machinery use. He owns a mini tiller and rents other machinery as needed. This year, with support from NSAF, he used a drone to spray fertilizer on his spring maize, significantly reducing labor and time.
“I have viewed videos of drones spraying fertilizer but never imagined it happening on my spring maize land. As a demonstration, 0.57 ha was used for nano urea spraying. The task was completed within five minutes of the drone taking flight. Similarly, I was astonished to learn that a drone can cover 2.02 ha in a mere 20 minutes,” he shared.
Intercropping and future plans
Rajendra has also implemented intercropping, combining maize with legumes on a 0.10-hectare plot. “Spring maize-legume intercropping is productive and effective for farmers such as me. We can make a profit from legumes, as well as spring maize. I will continue using this practice in the future,” he said.
Financial investments and community impact
The profits from agriculture have helped Rajendra to manage his household comfortably. He can now provide education for his four children, manage household expenses, and also pay the loan that he had taken for his household expenses. In addition, he recently invested NPR 250,000 (US $1,880.71) to build a new pig shed. He also sells his produce in local markets at Joshipur, Kailali.
“I have travelled a long way from being a subsistence farmer to engaging in commercial farming. This shift from traditional to improved farming technologies has been made possible with the support of NSAF/CIMMYT. I am grateful for their assistance and encouragement,” Rajendra said.
Vision for sustainability
Rajendra’s story reflects his dedication and hard work. “I was working as a daily wage laborer in India, hoping to secure a promising future for my children. Today, I can achieve complete sustainability through agriculture and provide quality education and a better life for my children,” he shared.

On Pemba Island, part of Tanzania’s Zanzibar archipelago, more women are engaging in vegetable production and value addition, bolstering household nutrition and income security. This movement is significant in areas where modern agricultural technology and awareness of nutrient-rich crops like amaranth—a vegetable high in fiber, protein, and essential micronutrients—are limited.
Mariam Salim, who lives in Mjini Ole village on Pemba Island, is among the women embracing amaranth cultivation. Along with 272 other farmers, 53% of whom are women, she attended a three-day training course on vegetable cultivation and value addition. Funded by the United States Agency for International Development (USAID), through CIMMYT under the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) project, and implemented by the World Vegetable Center, the training covered good agricultural practices, as well as the cultivation and processing of grain amaranth into flour.
The training equipped Mariam with essential knowledge and skills to enhance her agricultural productivity and livelihood.
Sowing seeds for success
Participants received seed kits containing eight varieties of nutritious traditional African vegetables, including African eggplant, African nightshade, amaranth, cowpea, and Ethiopian mustard. Farming a diverse range of crops supports food security and improves community nutrition.
During the training, Mariam realized the potential of growing grain amaranth for seed production. “I discovered that I could produce my own seeds and amaranth flour,” she said. “This opened up new opportunities for me to take control of my farming practices and increase my self-sufficiency.”
Seed production is a vital part of sustainable agriculture, enabling farmers like Mariam to boost productivity, diversify crops, and adopt climate-smart practices. By venturing into seed production, Mariam not only gained a valuable skill but also contributed to conserving and propagating important crop varieties within her community.
Mariam now sells seeds to other farmers, providing her with a new income source while supporting the broader agricultural community by facilitating access to quality seeds. Since the training in July 2023, Mariam has harvested 150 kg of seeds, selling them per kilogram (kg), earning US $450 and enhancing her household income security.
Healthy choices for communities
As the first woman in her community to undertake such an endeavor, Mariam is inspiring other women to explore new farming and food processing opportunities. Through the AID-I project on Zanzibar Island, more than 500 women have started home gardening to access quality vegetables for family consumption and business purposes, introducing new crop varieties and increasing household vegetable consumption.
This light bulb moment underscores the transformative power of education and knowledge-sharing initiatives under AID-I. By providing farmers with information on vegetable grain production and value addition, the project fosters self-reliance and innovation in sustainable farming practices.
Mariam’s detailed description of her seed production process highlights her dedication to agricultural innovation and community health. “It takes three months to harvest seeds, so I must be patient and committed to nurturing healthy crops,” she said. “I must also be precise in caring for the seeds through harvesting, drying, tapping, and sifting.”
The World Vegetable Center promotes home gardening among women. More than 500 participants actively cultivate and process vegetables into nutrient-dense packs. By growing their own vegetables, these women access nutritious food for their families, generate income from surplus produce, and improve health and well-being within the community.

As the summer cultivation season began in May 2024, Fatima Hassan, a 52-year-old farmer from New Halfa, Kassala State, in eastern Sudan, faced an uncertain future. Like thousands of other farmers in her region, Fatima lacked the financial means to purchase seeds, fertilizers, herbicides, or even hire a tractor. The ongoing armed conflict in Sudan had severely disrupted agricultural activities, leaving farmers without the necessary resources to cultivate their land.
‘When I learned about the Sudan Food Security Initiative (SFSI), I was extremely happy. The support from the initiative has given me and my family renewed hope,’ Fatima said while tending to her groundnut farm.”

Under the aegis of the SASAS program, the USAID-funded SFSI was launched in May 2024 in response to Sudan’s food security challenges. Targeting over 50,000 farmers in the New Halfa scheme, the initiative aims to strengthen resilient food production systems by providing significantly subsidized agricultural inputs and technologies, ensuring that farmers can sustain and enhance their farming practices despite the ongoing conflict in the region.

Sowing seeds of optimism
‘Support from SASAS came at a critical time as the armed conflict spread into new areas across the country, de-risking the crucial summer planting season. Through the SFSI, we are enabling farmers to adopt improved technologies and inputs at more affordable rates, thereby enhancing Sudan’s domestic food production,’ said SASAS Program Chief of Party Abdelrahman Kheir.
The SFSI provides each farmer with a 70% subsidy on a comprehensive package that includes land preparation for 0.42 hectares (ha), improved seeds for groundnut and sorghum, crop protection supplies, fertilizers, and agricultural advisory services. This initiative has already resulted in the planting of 14,568 ha of sorghum and 5,882 ha of groundnut. The crops are showing promising signs, with germination progressing well across all cultivated areas.
‘We had lost all hope of benefiting during this cultivation season. The subsidized land preparation, seed purchase, and other inputs have given us a lifeline. In the past, I was not able to buy fertilizers and herbicides, so my sorghum production was poor. This time things have changed dramatically, and we are well-equipped for a good cultivation season,’ said Hamid Rahama, a farmer from northern Halfa. Hamid echoes the optimism shared by many farmers in the region.”
Focus on a sustainable and food secure ecosystem
One of the most significant aspects of the initiative is its focus on building a sustainable seed production system. In partnership with 120 farmers and a private seed company, 252 ha (189 ha of sorghum and 63 ha of groundnut) were established for seed production in New Halfa. The initiative is projected to yield 360 metric tons (t) of sorghum and 270 t of groundnut seeds, thereby enhancing the resilience of the local agricultural ecosystem.
The anticipated yields from these efforts instill a much-needed optimism in an otherwise challenging situation. For groundnuts, the expected yield is 4.5 t/ha, resulting in an output of 26,000 t, enough to meet the nutritional needs of over 1.2 million people. Likewise, the sorghum harvest is projected to reach 54,000 t, providing sustenance for approximately 720,000 people.

The bold sections indicate the changes made for grammatical correctness, including unit consistency and phrasing adjustments.
In addition to providing inputs, the SASAS program also addresses broader food security challenges by ensuring that farmers receive the necessary technical support throughout various agricultural operations. This includes the introduction of drought-tolerant sorghum varieties, which are showcased to farmers through field days and demonstration plots.
Despite the numerous challenges posed by the ongoing conflict in Sudan, CIMMYT and its partners involved in implementing the SASAS initiative remain undeterred. Although the ongoing armed conflict has compelled many local agriculture advisory companies to scale back their operations due to security and logistical difficulties, the teams remain committed to supporting Sudanese farmers and improving agricultural productivity, thereby contributing to Sudan’s overall food security.
‘We lost a significant number of improved seed production fields due to the conflict. Nevertheless, we ensured the provision of all necessary certified seeds for the SFSI, along with top-quality herbicides,’ said the CEO of Harvest Agricultural Company Isam Ali. He added that despite considerable challenges in transporting agricultural machinery due to security issues, the company completed all land preparations in a timely manner for farmers.
The early impact of SFSI is evident in the renewed hope and optimism among farmers in New Halfa, who are now better equipped to face the challenges of the summer cropping season and contribute to the nation’s food security. With the harvest dates approaching—November for groundnuts and December for sorghum—the initiative is on track to significantly enhance food production in the region, providing a lifeline to thousands of farmers such as Fatima and Hamid.

Climate change is upending weather patterns across Africa, presenting dire challenges for farming communities. In Zambia, the impact is particularly harsh. Agriculture is the lifeblood of the economy, with two-thirds of the country’s workforce employed in agriculture, and 78% of these workers are women.
The country faced a severe El Niño during the 2023/2024 season, causing a severe drought that devastated over 1 million hectares of cropland. The president declared it a national disaster. El Niño events typically result in catastrophic drops in crop yields, often reducing maize harvests by 30-40%. These events not only impact food security but also hinder economic growth, with the agricultural sector’s contribution to Zambia’s GDP dropping from 9.4% to 3.39%.
The devastating El Niño-induced drought in Zambia is starkly illustrated by the story of Melody Limweta, a 31-year-old farmer. She and her husband, Collins Manenekela, have seen their already fragile livelihood pushed to the brink by severe water shortages. Typically, they rely on dry season gardening and small-scale farming, including raising chickens, during the rainy season. However, the drought has dried up local water sources, making gardening impossible and sharply reducing their income. The couple’s practice of planting maize in the same field each year with recycled seeds and traditional methods has worsened their situation, as the El Niño-induced rainfall deficits have led to poor yields. Their primary source of food and income has withered in the field due to insufficient rainfall.
A consortium of partners led by the International Maize and Wheat Improvement Center (CIMMYT) have joined together as a rapid delivery hub for these challenging times, providing vital support to rural communities and families such as Melody and Collins. Farmers have a strong voice in this unique delivery mode. With support from the people of the U.S. government, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) is promoting access to drought-tolerant crops, climate-busting and nutritious legume seeds, agricultural advice and early warning systems to combat climate change. AID-I provides critical support to ensure that millions of smallholder farmers in the Haut-Katanga region of DR Congo, Malawi, Tanzania, and Zambia have access to information and innovations needed for gains in food production that help buffer drought, flood and rising food, fuel, and fertilizer prices.
Speed and Scale: planting drought-tolerant maize
The idea of the ADI-I as a rapid delivery hub is to make available innovations and agronomic information at both speed and scale. Traditional farming methods and crops struggle with climate extremes like El Niño, which bring prolonged dry spells and heatwaves. Drought-tolerant maize varieties offer a promising solution by enhancing agricultural resilience. These adapted maize varieties yield 30-50% more than traditional ones under drought conditions, as demonstrated in recent trials during El Niño periods. However, these improved varieties are only useful when in farmers’ hands.
Working with local partners, AID-I is scaling drought-tolerant maize varieties to help Zambian farmers manage unpredictable weather patterns. In the 2023/2024 season, approximately 27% of Zambia’s smallholder farmers saw a significant boost in their maize harvests, benefiting over 900 thousand people in drought-affected regions, owing to drought-tolerant maize varieties. Over six hundred thousand households planted drought-tolerant maize varieties and produced 235 thousand metric tons of maize, accounting for 19% of Zambia’s maize production in the 2023/2024 season. This is huge return, as only 10% of the maize-growing area being planted with these resilient varieties.
Crop diversification for family nutrition
In addition to drought-tolerant maize, studies indicate that diversifying with legume crops is crucial for managing weather extremes, especially droughts and for improving soil health. Planting legumes helps spread the risk with varied planting and harvest times, cushioning the impact of erratic rainfall on crop yields. Women can feed their families due to crops like peanuts that mature early and need less rainfall. The benefits are sustained over time, as combining legumes with cereals improves overall nutrition and soil health, even amid unpredictable weather.
To support this effort, AID-I linked over 2,000 farmers to high-quality seeds for groundnuts (peanuts) and soybeans. On average, each household harvested about 80 kg of groundnuts and 175 kg of soybeans, earning roughly $75 and $58, respectively. Collectively, this initiative produced about 205 metric tons of these crops, accounting for around 14.3% of Zambia’s total production in the drought-stricken season. Farmers had a voice in choosing which crop varieties to grow through a feedback system called ‘let’s chat’ where with an ordinary flip phone farmers could call in and learn from their neighbour’s recorded commentary and testimonials. For the first time ever, farmers could provide comments on which crops they preferred, providing a lifeline of communication with agritraders, government and agricultural advisors.
A recent assessment found that Zambian women made up 60% of those benefiting from cowpeas, 65% from groundnuts, 62% from soybeans, and 36% from drought-tolerant maize.
Forewarned is forearmed – early-warning systems
Weather information services, especially early warnings about upcoming droughts, are vital for helping farmers adapt to climate change. Accurate and timely weather forecasts enable farmers to make informed decisions about planting, resource use, and crop management. This reduces losses and boosts productivity. Research shows that access to climate information can significantly increase crop yields and incomes, with some farmers experiencing up to a 66% boost in yields and a 24% rise in income.
The forecast of an El Niño for the 2023/2024 season prompted an early warning campaign to raise awareness about the hazards associated with El Niño and provide response mechanisms for smallholder farmers. AID-I used an Interactive Voice Response platform hosted by Viamo, a global social enterprise that uses mobile technology to connect people to valuable information and services. This rapid El Niño advisory campaign reached over 500 thousand farmers, with 60% male and 40% female listeners, and 93% of them under 35 years old. The campaign provided crucial advice on planting schedules, drought-resistant crops, and water-saving techniques.
Additionally, AID-I established demonstration sites that showcased effective winter crop production methods and introduced over 2,000 farmers to innovative agricultural practices. These interventions significantly improved farmers’ ability to respond to the drought.
Looking ahead
Scaling the adoption of drought-tolerant maize, improved legumes, and timely advisories is vital to protecting Zambia’s agriculture from climate extremes. The introduction of an AID-I-supported digital advisory campaign in September 2023 was a turning point for farmers like Melody and Collins. By engaging with the content, they learned about improved seeds, crop rotation, and better agronomic practices, which helped them cope with ongoing challenges and protect their resources. Initiatives like this can help families on the margins survive and rebuild agricultural production faster.
AID-I’s impact on families like Melody and Collins shows that investing in rapid delivery hubs is crucial for building resilience in farming communities. Expanding such initiatives will ensure more smallholder farmers have access to the innovations needed to maintain or increase food production amid climatic challenges.
Additionally, studies by organizations like Springer and the American Geophysical Union highlight the importance of integrating rapid delivery hubs into mainstream agricultural programs to enhance climate resilience and food security. Therefore, this necessitates an open call for international development allies—including donors, governments, NGOs, and businesses—to incorporate initiatives like AID-I into broader agricultural agendas, essential for fostering resilience and ensuring the future stability of farming communities in Zambia and beyond.

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.
“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.
The launch of the ‘Rajaram-DCM Shriram Scholarship’ to foster the next generation of agricultural scientists and the unveiling of Dr. Sanjaya Rajaram’s bust at the DialogueNEXT conference in Mexico were significant initiatives.
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.”
Directors from Excellence in Agronomy visit modules and platforms at CIMMYT’s South Pacific Hub in Oaxaca, Mexico (Photo: CIMMYT)
“It was a stunning experience for me to understand the operation of a hub and see farmers interact directly with field technicians, applying the principles of Conservation Agriculture. I remember a lady from Oaxaca telling us how productive she has become using la matraca, a simple, manual seeder and fertilizer,” says Mandla Nkomo during his recent visit to the Mixteca oaxaqueña in southern Mexico.
Mandla is the chief growth officer for the Excellence in Agronomy Initiative (EiA) which, “gathers more than 10 CGIAR Research Centers whose goal is to create solutions to problems that farmers face globally. EiA works on a foundation that is driven by demand to understand the challenges farmers are dealing with, and bring forth a development system for innovation that is capable of coping with those challenges and finding solutions that can be tested, validated, and scaled,” he mentions.
His searching for a system that triggers and diffuses innovation for farmers motivated Mandla to visit the hubs in Oaxaca, Mexico. “We are here because we wanted to study all the hubs and the projects based on the methods CIMMYT and its collaborators have developed in Mexico. One of the things we consider at EiA is the successful and sustainable transition from individual use to working within a partner network.”
“What we have seen here is the work of our colleagues from CIMMYT. For the last decade, they have come up with these hubs or innovation centers situated across different agroecological regions in Mexico. What is unique about the hubs is the ecosystem they are creating, which in my opinion, is what brings excellence in agronomy,” says Mandla.
The hubs are a management approach for innovation that was developed in Mexico based on initiatives like MasAgro-Cultivos para México. Due to its big impact, it’s being replicated in Asia, Africa, and in other Latin America countries. In addition, it lies in the heart of CGIAR initiatives.
About this methodology, Mandla says those who participate in it, are trying to understand the challenges that farmers truly face. Then a platform is developed to do proper research that responds to farmers’ needs. Subsequently, they test it in modules which provides proof of the impact these solutions are having as compared to conventional farming. Finally, these solutions are transferred to areas called extension, from which large-scale innovations are implemented.
During his visit to the research platform in Santo Domingo Yanhuitlan and to modules for innovation, extension areas, seed warehouses, post-harvest modules and machinery locations at different towns in Oaxaca, Mandla Nkomo and other visitors from EiA had the opportunity of learning not only how the South Pacific Hub operates but also witnessed how this management approach for innovation is socially and culturally relevant to one of the most diverse regions in the country.
“These days have been truly amazing. They have been very useful in refining the picture of what’s possible to do and scale. Mexico is a megadiverse country with varied agroecology. Our approach can be replicated in many parts of the world. I’m very excited with what we have seen. The country that gave us corn is now providing the world with solutions that will have major impacts on global food security. So, it is now our task (me and the whole EiA team) to find ways to pass this on to other latitudes”.

Stronger partnerships, innovation, and agile science for impact were resounding themes when CIMMYT researchers from the Sustainable Agrifood Systems (SAS) program in Africa gathered in Nairobi to develop the program’s implementation roadmap in alignment with the CIMMYT 2030 Strategy.
The three-day retreat from 25-28 March, attended by research teams from the eastern, western, southern, and Horn regions of Africa, provided a platform to share insights and chart a course towards sustainable agricultural development for the continent.
Routes to amplifying research impact
In her opening remarks, SAS Program Director, Sieglinde Snapp, emphasized the importance of grounding the CIMMYT 2030 Strategy in the African context and the urgent need for actionable plans to address pressing challenges in agrifood systems. Snapp drew attention to the significance of collaboration with public, private, and civil society stakeholders, highlighting how inclusive partnerships are essential for driving meaningful change. She urged the team to focus on turning strategic vision into tangible plans, with clear milestones to track progress.
“Humanity pulled together and got to the moon in the 60s. Conventional science and engineering got us there,” said Snapp. “However, when we have high uncertainty and high-value conflicts, we need to have all stakeholders at the table. We need to do action science and think of what the actual science looks like.”
Christian Witt, senior program officer at the Bill & Melinda Gates Foundation, delivered a keynote address focusing on the importance of advancing agronomy globally and exploring opportunities at the national level. He advocated for a balanced approach to tackling macroeconomic challenges while fostering grassroots innovation that augments impact. He also underscored the CIMMYT 2030 Strategy’s critical role across CGIAR, calling for a pivot in funder influence towards a unified, demand-driven research methodology.

Deep diving into the strategy
The retreat also featured a panel discussion on the CIMMYT 2030 Strategy. From the value of strategic partnerships to the need for excellence in research and delivery, the panel highlighted the key pillars of CIMMYT’s strategy and underscored the importance of aligning efforts with global priorities and challenges.
Participants discussed the role of data systems for agile agronomy, noting the need for innovative methodologies to harness the vast amount of data available. They placed key focus on empowering farmers, particularly through initiatives like the BACKFEED Farmer Agency. This inclusive feedback system enables knowledge co-creation via mobile phones, fostering networking among farmers of diverse backgrounds. Regular and spontaneous interactions facilitate data collection, addressing social exclusion in agricultural information channels faced by those with multiple vulnerabilities.
Paswel Marenya, SAS associate program director for Africa, shared thought-provoking insights on the Pathways to Impact. He demonstrated how complementarity and bundled approaches, impact orientation, evidence-supported scaling, subsidiarity, localization, and training of farmers and communities, and inclusive seed systems, can transform food systems.
During an analysis of the strategy in the African context, central inquiry focused on identifying areas where SAS could deliver the greatest value. Discussions revealed a consensus on several key priorities: the need of developing and implementing policies from the ground up, addressing the specific needs of smallholder farmers, enhancing capacity for sustainable development, ensuring inclusivity for youth and women, expanding innovative solutions, and encouraging regional collaboration. These common themes highlight a united drive towards comprehensive and impactful agricultural advancement across Africa’s diverse landscapes.
On implementing the strategy, attendees discussed a range of plans and proposals:
Diversify from maize to alternative crops, such as pigeon peas.
Engage stakeholders in agile agronomy discussions to identify impact pathways.
Train the private and public sectors for climate-smart agriculture.
Address concerns regarding prevailing inefficiencies within the formal seed system and the lack of business models for non-hybrid seeds like groundnut or wheat.
Identify opportunities for financial inclusion through aggregator and off-taker models.
Consider the importance of mechanization policies, markets, and extension services.
Engage strategically in the humanitarian-development-peace nexus, as the majority of food insecurity is found in conflict areas.
Improve nutrition education and meet local demand for nutritious crops like pigeon pea and groundnut.
Consider the role of data and analytics in humanitarian-development-peace pathways, policy engagement for building value chains, and the significance of impact pathways.
Promote the importance of open science, data sharing, and addressing gaps between product enhancement and production.

Eyes on the future
In reflections at the end of the retreat, Snapp reiterated the importance of investing in soil resilience through agile agronomy and participatory research to foster collaboration and inclusivity in decision-making processes. She focused on the significance of foresight targeting and market intelligence, particularly in regions grappling with soil degradation and the impact of the climate crisis. Her presentation highlighted key priorities for driving impactful agricultural development, including effective data management, climate adaptation, and alignment of existing solutions with climate goals. The interconnectedness of foresight targeting, seed systems, and agile agronomy was underscored, emphasizing the importance of collaboration and addressing essential topics like nitrogen and climate change. Additionally, Snapp reiterated the crucial role of collaborative efforts between different teams and organizations in effectively advancing agricultural research and development initiatives.
To cap off three days of intense discussions and strategy-building, participants took part in fun team-building activities that echo CIMMYT’s core values of excellence, integrity, and teamwork.
Maize is the second most important cereal in Laos after rice, driven primarily by the demand for animal feed in neighboring countries such as China, Thailand, and Vietnam. Laos has an export-oriented maize sector, with most of the country’s production destined for these markets. The sector reached its peak in 2016, when production levels hit 6 metric tons per hectare across an area of 0.26 million hectares.
Over 90% of Laos’s maize production relies on rain-fed agriculture, with maize grain and stover serving as the primary source of feed for smallholder farmers who depend on mixed crop and livestock farming systems for their livelihoods. However, between 2016 and 2022, total maize area and production declined significantly, contracting by 64% and 70%, respectively. Several factors contributed to this decline, including volatile market prices, competition from cassava and other crops, rising production costs, and yield losses due to pests, diseases, and soil nutrient degradation because of monocropping.
Additionally, Laos relies on imported hybrid maize seed, primarily from Thailand and Vietnam, which creates a dependence on external suppliers and exposes farmers to price fluctuations. Recognizing the importance of improving maize productivity and sustainability, the Laotian government is taking steps to enhance local capacity for seed production and ensure access to affordable high-quality feed.
Enhancing local hybrid maize seed production
Recognizing the importance of enhancing the availability and accessibility of quality maize seed and feed, CIMMYT and Laos’s National Agriculture and Forestry Research Institute (NAFRI) have initiated the evaluation of high-yielding maize hybrids for both grain and stover quality. In 2023, 12 yellow-kernel maize hybrids developed by the CIMMYT-Asia breeding program underwent evaluation in Laos. The same set of hybrids is undergoing evaluation in 2024 to identify stable and suitable germplasm. According to Siviengkhek Phommalath, director of the rice and cash crop research center at NAFRI, the 2023 evaluation provided promising results, with at least two hybrids performing better or on par with widely grown commercial ones in Laos. These hybrids exhibit high productivity, particularly in terms of grain and stover quality. However, further validation is planned for 2024, with the introduction of additional testing sites to assess performance across various environments.
Following thorough evaluations across multiple years and environments, the most suitable dual-purpose maize hybrids will be allocated to NAFRI by CIMMYT along with their parental lines, to kickstart local seed production. However, the capacity of national partners needs to be strengthened to initiate local hybrid maize seed production effectively, and this necessitates the integration and coordination of efforts among all stakeholders in the seed and feed value chains in Laos.
Capacity building across seed and feed value chains
In response to the need for capacity building in local hybrid seed production and ensuring a consistent supply of high-quality seed and feed to Laotian smallholder farmers, NAFRI has collaborated with CIMMYT under the CGIAR Sustainable Intensification of Mixed Farming Systems (SIMFS), Seed Equal, and Plant Health Initiatives to organize an international training workshop on enhancing access to quality maize seed and feed in the crop-livestock farming system of Lao PDR, which took place from May 7-9, 2024.

The three-day interactive workshop, held in Vientiane, brought together 28 specialists from various organizations, including NAFRI, Souphanou Vong University, the Upland Agriculture Research Center (UARC), Provincial Agriculture and Forestry Offices (PAFO), as well as maize seed importers and grain traders from different provinces within the country.
The first day was dedicated to understanding the challenges and opportunities of the maize seed value chain. Participants were divided into three groups based on their practical backgrounds and invited to discuss challenges, stakeholder roles, and develop actionable recommendations for better coordination across value chains. This multi-stakeholder platform aimed to comprehend the challenges and opportunities of the crop-livestock farming nexus and integrate them into a more sustainable and productive system. It also served as a forum to promote synergistic partnerships among value-chain actors in enhancing local access to good quality seed and feed. The following days focused on various essential components of quality hybrid seed production, including understanding product profiles and market segments, realizing the economics of hybrid maize seed production, seed quality assurance, management of maize pests and diseases, and enhancing maize stover quality.
A collaborative approach
Workshop participants highlighted the challenges they face in acquiring maize seeds from external sources, citing inconsistent delivery times and limited availability of preferred varieties as factors that posed significant operational constraints. “The development of a competitive domestic maize seed system would ensure timely seed supply for farmers and save resources for the nation,” said Maisong Yodnuanchan, an agripreneur from Xiangkhouang province. His concerns resonated with fellow agripreneurs Bounmy Si and Teuang Sophapmixay, from Oudomxay and Hua Phan provinces, respectively, who both acknowledged the challenges associated with the current reliance on imported seeds and the potential benefits of a sustainable, locally produced seed supply.

The training workshop offered valuable insights into addressing these concerns, providing a comprehensive overview of effective seed system development and the technical aspects of seed production applicable to a wide range of crops beyond maize. “This is the first ever training I received in my career and the knowledge gained will be directly applicable to my research activities at the UARC,” said researcher Malay Soukkhy. Recognizing the unique context of Laos compared to most of its neighboring countries with more established seed systems, AbduRahman Beshir, CIMMYT’s seed systems specialist for Asia and the lead trainer and facilitator for the workshop, emphasized the need for a collaborative approach to develop a custom solution for Laos. The workshop itself exemplified this collaborative spirit, incorporating a variety of engaging formats such as group discussions, lectures, assignments, and participant presentations. Subject matter specialists from CIMMYT offices in Nepal, India, and Kenya, as well as experts from Alliance Bioversity-CIAT and ILRI offices in Asia, shared valuable experiences applicable to Laos’s seed and feed systems.
Cementing partnerships
While addressing the participants, Timothy J. Krupnik, regional director for CIMMYT’s Sustainable Agrifood Systems Program in Asia, opened the workshop by acknowledging the invaluable support of NAFRI for organizing the event and collaborating under the CGIAR mixed farming initiative. He highlighted the imminent finalization of a Memorandum of Understanding (MoU) between CIMMYT and NAFRI, which will pave the way to further cement partnerships and establish a long term CIMMYT operations in Laos.
NAFRI’s Director General, Chanthakhone Bualaphan, presided over the workshop and emphasized the importance of continued collaboration between CIMMYT and NAFRI. Bualaphan requested CIMMYT’s continued focus on capacity building in Laos, encompassing both human resource development and institutional strengthening. She further highlighted the establishment of a specific target for domestic hybrid maize seed production, aligning with the government’s self-sufficiency goals. To translate plans into action, Bualaphan emphasized the need for future training programs to be more action-oriented and practical. She concluded by reiterating NAFRI’s unwavering support for CIMMYT’s expanded activities in Laos, with the ultimate objective of significantly improving the livelihoods of Laotian farmers. The workshop culminated with the presentation of certificates to participants and the development of a collaborative follow-up plan for deploying well-tailored maize germplasm within the mixed farming system of Laos.

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.
