Climate change threatens to reduce global crop production, and poor people in tropical environments will be hit the hardest. More than 90% of CIMMYT’s work relates to climate change, helping farmers adapt to shocks while producing more food, and reduce emissions where possible. Innovations include new maize and wheat varieties that withstand drought, heat and pests; conservation agriculture; farming methods that save water and reduce the need for fertilizer; climate information services; and index-based insurance for farmers whose crops are damaged by bad weather. CIMMYT is an important contributor to the CGIAR Research Program on Climate Change, Agriculture and Food Security.
With food insecurity affecting 733 million people worldwide, the need for solutions is urgent as World Food Day draws near. CIMMYT’s leadership in promoting sustainable agricultural systems is exemplified by Sieglinde Snapp, Director of the Sustainable Agrifood Systems Program, who emphasizes the role of biodiversity in building resilient food systems. By encouraging the use of resilient crops like millet and sorghum, CIMMYT is working to improve soil health and enhance farmers’ livelihoods, especially in regions like sub-Saharan Africa. Empowering women and ensuring smallholder farmers have access to resources are key elements in transforming global food systems, a cause CIMMYT is deeply invested in.
Malho Marndi, a tribal farmer from Odisha,India, has been cultivating rice on her 10-acre farm for many years. However, worsening climate conditions and labor management challenges nearly pushed her to stop growing rice, except for personal consumption. The traditional method of transplanting seedlings into puddled fields was becoming unsustainable, and farmers across Odisha were experiencing yield declines that threatened their livelihoods.
To address these challenges, the Cereal Systems Initiative for South Asia (CSISA) project led by CIMMYT, introduced the Direct Seeded Rice (DSR) technology in select districts under the Odisha government’s DSR-Odisha project. DSR involves sowing rice seeds directly into the field, significantly reducing the need for labor and water—making it an attractive solution for smallholder farmers.
In the Kharif season of 2021, Malho participated in a DSR awareness program led by CSISA. Inspired by the success stories of fellow farmers, she decided to take a leap of faith and implement DSR on her own land.
The results were transformative. By adopting DSR on her 10-acre farm, along with an additional 9 acres she had leased, Malho saw her yields nearly double compared to the traditional methods she had previously used. Encouraged by these outcomes and supported by CSISA’s technical guidance, she expanded her cultivation to 40 leased acres and her original 10 acres in 2022. By 2023, she increased her leased land to 50 acres, bringing the total area under DSR to an impressive 60 acres.

Malho’s success didn’t end there. She became a service provider, investing in a tractor and rotavator to assist other smallholder farmers in her community. In 2023 alone, her machinery was used to support more than 30 acres of land. Today, she empowers both men and women farmers by renting out her equipment and encouraging the wider adoption of DSR.
Through mechanization and improved crop management practices, Malho now independently manages her rice and maize cultivation. Confident about the future, she hopes to see more resource-constrained farmers across Odisha adopt DSR, improving their yields and enhancing their livelihoods.
Rice is a critical staple for food security and a key export crop for India. The study published in Nature Communications explores context-specific pathways for increasing rice production in India, focusing on sustainable intensification — boosting yields without harming the environment or farm profitability.
The research analyzed over 15,000 field records across seven major rice-producing states in India using advanced machine learning techniques. The study identified nitrogen application and irrigation as key factors limiting yields, particularly in Eastern India (Bihar and Uttar Pradesh). By targeting farms with nitrogen and irrigation deficiencies, the study projects that yield gains could more than triple compared to general recommendations. Specifically, farms suffering from co-limitation by both nitrogen and irrigation could see the most significant gains in productivity and profitability.
Four scenarios for sustainable intensification were evaluated, ranging from blanket application of current nitrogen recommendations to highly targeted interventions. The analysis showed that targeted strategies, focusing on farms with the greatest yield constraints, could significantly improve nitrogen use efficiency and result in greater yields and profitability without excessive resource use.
The study highlights the potential of data-driven, context-specific solutions for rice intensification in India, emphasizing that targeted interventions could offer both higher returns for farmers and better environmental sustainability. It suggests a move away from “one-size-fits-all” approaches towards more precise, farm-specific recommendations based on local conditions and data. This approach could help close yield gaps while aligning with sustainable development goals.

When she first ventured into growing pigeon peas as a baby trial host farmer, Gogo Consilia Nyamunda doubted that intercropping them with maize would bring any benefits, especially given the weather had not been lenient over the past few years in Buhera district, in eastern Zimbabwe. “This year has been the hardest. I’ve never experienced such drought and heat stress, but it’s not just me—it’s affecting the entire country,” says Gogo Consilia. Yet, her production turned out to be better than that of farmers growing only maize, a popular crop in Southern Africa. Encouraged by the results, she expanded her efforts, dedicating half a hectare to pigeon peas. “From just 0.2 hectares of pigeon peas, I still managed to harvest 10 kilograms in these extremely dry conditions. It’s not just for feeding my chickens—other farmers are now interested in the seeds as well,” she explains.
In the face of a changing climate, building the resilience of local farmers is crucial to safeguarding both their meal baskets and livestock feed. In this context, LIPS Zimbabwe has emerged as a strategic initiative, deeply rooted in farmer-driven trials to scale fodder production while maximizing the potential of mechanization for smallholder farmers in Buhera. By integrating improved agronomic practices with scalable fodder production, LIPS Zimbabwe is helping farmers withstand the challenges posed by climate change.
Empowering local farmers through fodder production
In the same district, Shirley Makoni also began as a baby trial farmer, intercropping maize with jack bean, a leguminous crop resilient to drought. Her case highlights the importance of diversifying crops and adapting to the realities of climate change: despite initial skepticism, Shirley found that jack beans not only survived the drought but also provided valuable feed for her cows. “I didn’t think anything would come out of it, but the cows love the leaves and seeds. They’ve gained weight, and the crop has been easy to manage,” she shares. While her maize and other crops failed due to the severe weather, jack bean proved to be a reliable source of feed, allowing her to bale the leaves and even share the harvest with others.

One of the key strategies employed by LIPS Zimbabwe is the promotion of resilient fodder crops that can thrive under harsh climatic, semi-arid conditions where potential evapotranspiration far exceeds seasonal rainfall, which is often below 600 mm. This approach not only ensures a reliable source of feed for livestock but also contributes to the overall resilience of farming systems. The success story of farmers like Gogo Consilia Nyamunda highlights the transformative impact of these efforts.
“The idea of testing new innovations has paid off. Despite the poor sandy soils in Buhera, these fodder crops (jack bean and pigeon pea) have done well!” says Isaiah Nyagumbo, a Systems Agronomist leading the CIMMYT component of the LIPS-Zim project. “This means we now have a more diverse range of leguminous fodder crop species that can be grown in these semi-arid conditions, apart from the more common ones such as mucuna, lablab, and cowpeas.”
Some preliminary laboratory results also suggest that jack bean contains much higher crude protein than popular fodder legumes like mucuna. Jack bean could thus offer a new resilient feed option for farmers in these drought-prone regions and can be grown as an intercrop or in rotation with cereals.
Transforming fodder production through mechanization
Tying the LIPS Zimbabwe project together is the introduction of the mechanization component, from planting to processing the fodder crops, which is crucial for increasing the scale of fodder production in Zimbabwe’s semi-arid regions. By processing forage legumes such as jack bean, lablab, pigeon pea, mucuna, and cowpea, farmers can ensure a steady supply of nutritious feed for their livestock, even in the face of unpredictable weather patterns.
Local farmers in Buhera have been equipped with machinery such as a chopper grinder, hay balers, planters, and tractors, and trained to use and maintain the equipment. “Among the machinery at hand, the hay baler has been a great win for me, especially for the cows,” says Gandani Nhachi. “Last season, I made 27 bales of fodder, which has been vital for my herd. I’ve also grown my goat herd from 16 last year to 35 this year,” he proudly shares.
Building resilience for the future
As climate change continues to challenge farmers, initiatives like LIPS Zimbabwe are essential for building resilience. By combining traditional knowledge with modern practices, scaling fodder production, and embracing mechanization, farmers in Buhera are better equipped to protect their livelihoods and ensure food security. As Gandani puts it, “Climate change is inevitable, but with the right practices, we can still thrive. When I give my goats food, they multiply. Even if one side fails, all hope is not lost.”
That’s how much farmers have saved this century, through use of disease-resistant wheat varieties. Modern wheat can thank its “wild relatives” — grassy cousins millions of years old and tested through extremes of earth’s climate — for most of its resistance genes.
Despite such remarkable achievements in wheat breeding, we’ve only scratched the surface of the genetic potential in wheat’s wild relatives. With climate change intensifying and the rapid evolution and spread of pathogens — a new strain of fungus can circulate in the jet stream—it’s imperative that we increase investment in researching this largely untapped genetic diversity. Doing so could revolutionize wheat production, ensuring food security while dramatically reducing agriculture’s environmental footprint.
Without such efforts, epidemics or pandemics could devastate yields, potentially leading to massive applications of toxic agrochemicals and increased selection pressure for pests and diseases to develop resistance. The consequences would be far-reaching, impacting not only food security and the environment, but also geopolitical stability, potentially triggering human migration and conflict.
Today, wheat is the most widely grown crop on Earth, providing 20% of all human protein and calories and serving as the primary staple food for 1.5 billion people in the Global South.
However, with its future under threat, standard breeding approaches can no longer keep up with the pace of climate change. Research shows that climate shifts from 1980-2008 reduced wheat harvests by 5.5%, and global wheat production falls 6% for every degree-centigrade increase in temperature.
Wheat science urgently requires enhanced investments to scale up genetic studies of wild relatives, utilizing next-generation breeding tools. These tools include gene sequencing technologies, big-data analytics, and remote sensing technologies. Satellite imagery makes the planet a laboratory, allowing researchers to monitor traits like plant growth or disease resistance globally. Artificial intelligence can super-charge breeding simulations and quickly identify promising genes that enhance climate-resilience.
The basic genetic resources are already available: more than 770,000 unique seed samples are stored in 155 seed banks across 78 countries. These samples represent the full scope of known wheat genetic diversity, from modern varieties to ancient wild relatives and landraces developed at the dawn of agriculture.
What’s missing is funding to accelerate the search for specific genes and combinations that will fortify wheat against harsher conditions. This requires political will from key decision-makers and public interest. Nothing is more important than food security and the environmental legacy we leave to our children.
Harnessing the power of microorganisms
The genetic variation in seed banks is largely absent in modern wheat, which became genetically separate from other grass species 10,000 years ago and has undergone recent science-based breeding, constricting its diversity. Wheat needs its cousins’ diversity to thrive in a changing climate.
Beyond climate resilience and disease resistance, wild wheat relatives offer another exciting avenue for environmental benefits: enhanced interactions with beneficial microorganisms. These ancient grasses have evolved intricate relationships with soil microbes largely absent in modern wheat.
Some wild wheat relatives can inhibit soil microbes that convert ammonium to nitrate. While both are usable nitrogen forms for plants, nitrate is more prone to loss through leaching or gaseous conversion. Slowing this process of conversion, called nitrification, has profound implications for sustainable agriculture, potentially mitigating greenhouse gas emissions, improving nitrogen-use efficiency, and decreasing synthetic fertilizer use.
As proof of concept, the first and only crop (so far) bred to promote microbiome interaction is wheat, using a gene from a wild relative (Leymus racemosus) to slow nitrification.
In addition, wild relatives often form more effective symbiotic relationships with beneficial soil fungi and bacteria, enhancing nutrient uptake, drought tolerance, and natural pest defenses. Reintroducing these traits could reduce chemical inputs while improving soil health and biodiversity.
The benefits extend beyond the field. Wheat varieties that use water and nutrients more efficiently could reduce agricultural runoff, protecting water bodies. Enhanced root systems could increase soil carbon sequestration, contributing to climate change mitigation.
By systematically exploring wild wheat’s microbial interaction traits, wheat varieties can be developed that not only withstand climate challenges but also actively contribute to environmental restoration.
This represents a paradigm shift from crop protection through chemicals to resilience through biological synergies. Indeed, even a fraction of the US $1.4 trillion spent annually on agrochemical crop protection could work wonders to fortify wheat against present and future challenges.
The path forward is clear: increased investment in researching wild wheat relatives can yield a new generation of wheat varieties that are not just climate-resilient, but also environmentally regenerative. This will be a crucial step towards sustainable food security in a changing world.
CIMMYT Director General Bram Govaerts’ visit to The University of Queensland (UQ) on September 27, 2024, reinforced a long-standing partnership aimed at tackling global food security and sustainability challenges. For over 50 years, CIMMYT’s collaboration with Australian researchers has advanced wheat breeding, contributing significantly to Australia’s agricultural resilience. The visit emphasized expanding research on key crops like sorghum, millets, and legumes, while promoting sustainable practices and climate resilience in agriculture. This collaboration continues to drive innovations that benefit not only Australia but also regions across the Indo-Pacific and Africa.
At the UN General Assembly, the U.S. Department of State announced $5 million in food security assistance to advance the Vision for Adapted Crops and Soils initiative in Guatemala. Co-led by CIMMYT and FAO, it aims to enhance sustainable agriculture through innovative practices that improve soil health and crop diversity. This initiative, part of the U.S. Feed the Future program, will strengthen resilience to climate change and support Guatemala’s agricultural sector, directly benefiting the 1.6 million people dependent on farming. CIMMYT’s leadership ensures scientific expertise in crop and soil management is central to addressing food insecurity and malnutrition in the region.
Soils are the bedrock for plant health and sustenance, but how do we protect and enhance them to maximize their nutritional potential? Years of conventional farming practices have left many soils depleted, raising urgent concerns about how to rejuvenate them. The recent El Niño event during the 2023/24 farming season in southern Africa, bringing extreme weather conditions—ranging from prolonged droughts to intense floods—has exposed the vulnerability of these soils. Poorly managed soils, already strained by years of excessive tillage and lack of cover, struggle to retain moisture under such stress, leading to crop failures even after rainfall.
However, conservation agriculture (CA) offers a vital solution. By improving soil structure and moisture retention, CA practices provide a lifeline for crops in challenging conditions. Recognizing this, CIMMYT scientists are actively promoting CA among smallholder farmers across sub-Saharan Africa, highlighting its critical role in sustaining soil health and resilience in the face of climate challenges.
Described as lumps of soil particles that bind together strongly, soil aggregates play a vital role in maintaining soil health, supporting plant growth, and sustaining agricultural productivity. Formed by the combined effects of biological, chemical, and physical processes, the structure and stability of soil aggregates are crucial for several soil functions—primarily water infiltration, root growth, and resistance to erosion. Soil aggregates consist of various soil particles, including sand, silt, clay, and organic matter. There are different types of soil aggregates, including macroaggregates (>0.25 mm) and microaggregates (<0.25 mm), with macroaggregates typically more stable and beneficial for soil structure and functions.
Demonstrating the value of soil aggregate stability

Imagine three soil aggregate samples taken from the same field but under different management regimes—from virgin soil that has not been previously cropped, to land under conservation agriculture practices for the last 5 to 8 years, and soil conventionally ploughed annually before crop planting for many years. When these soil aggregates are gently immersed in clear water, stark differences can be noted. The aggregates from conventionally tilled soil, weakened by years of intensive cultivation, quickly disintegrate, turning the water murky and brown.
In contrast, the aggregates from virgin soil remain intact, preserving the water’s clarity even after several hours. The CA soil aggregates exhibit much better stability than those from the conventionally tilled soil but fail to remain as intact as those from the natural virgin soil. A simple lesson is drawn from this demonstration! Restoring degraded soils is a serious challenge. Even after 5 years of CA practices, soil organic carbon levels may only show modest improvement, and the aggregates, while more stable, still don’t match the condition of aggregates from virgin soil.
Soil recovery from a degraded state is a slow process that is not “a walk in the park.” Transitioning from conventional tillage to CA is challenging and slow, requiring years to rebuild organic matter and improve aggregate stability. Patience and careful soil management are vital, as degradation can occur rapidly, but recovery is a lengthy process. However, incorporating organic soil amendments like manure and compost, along with diversifying crops by introducing legumes such as cowpea, groundnut, soybean, mucuna, and pigeon pea, can accelerate this recovery. While degradation occurs rapidly, soil restoration demands a long-term commitment, but the rewards are worth the effort.
Exploring conservation agriculture as a source to improve soil health
Conservation agriculture is built on three key principles: reduced soil disturbance, permanent soil cover, and diverse crop rotation. Minimizing soil disturbance helps preserve soil structure, while permanent soil cover shields the soil against splash erosion and boosts microbial activity. Crop rotation enhances soil fertility, maintains aggregate structure, and disrupts pest and disease cycles. These principles are essential for soil recovery and the retention of organic matter.
Among these, permanent soil cover is often the most challenging for farmers to implement, yet it is critical for effective soil management. Demonstrating its importance, a simple test with water applied to soil samples with varying levels of cover illustrates splash erosion effects.
“Such a simple test mimics real-life conditions farmers face during rains. Soils without cover suffer significant erosion, while those with minimal or substantial cover show reduced erosion and improved water retention. This emphasizes the importance of maintaining permanent soil cover to foster microbial activity and enhance soil health,” highlighted Isaiah Nyagumbo, cropping systems agronomist.
In a nutshell, soil aggregate management is fundamental to climate resilience and agricultural sustainability. Through the adoption of conservation agriculture practices, smallholder farmers can significantly improve soil health, enhance water and nutrient retention, and increase crop resilience to climate stress. The journey from degraded to healthy soil is long and challenging, but with careful management and patience, the benefits are profound and lasting. By understanding and implementing these principles, farmers can build a more sustainable and resilient food system.
Perth, Australia – September 24, 2024 – Esteemed Professor Matthew Reynolds, Head of Wheat Physiology at CIMMYT, will deliver a pivotal plenary at the International Wheat Congress, centering on enhancing abiotic stress tolerance in wheat through the integration of complex traits by combining cutting-edge artificial intelligence with genetic diversity. This significant session promises to contribute valuable insights towards addressing the pressing global challenge of food security.
Pioneering Research to Future-Proof Wheat
Crop yield depends on a myriad of traits that interact across various dimensions such as growth stage, plant architecture, and growing environment. Until now, the complexity of these interactions has impeded precision breeding for traits like abiotic stress tolerance, input use efficiency, and yield potential. However, recent advancements in AI, remote sensing, and gene sequencing are making more deterministic breeding feasible.
In his presentation, Professor Reynolds will introduce a series of wiring diagrams representing trait interactions over time for wheat. These diagrams, based on empirical data and crop models, will serve as a framework for AI-assisted simulations to explore different breeding strategies. This innovative approach enables the genetic control of complex traits, allowing for more resilient wheat varieties that can withstand environmental stresses.
Collaborative Efforts Driving Innovation
This initiative is a collaboration between CIMMYT, the University of Florida, University of Queensland, and Wageningen University. The goal is to leverage advanced technologies to combine complex genetic traits in wheat, improving its tolerance to drought, heat, and poor soil conditions. This research holds significant promise for farmers worldwide, ensuring stable yields even under challenging growing conditions.
Impact and Benefits
Global Food Security: By developing high-yielding, climate-resilient wheat varieties, this research contributes to global food security, particularly benefiting farmers in South Asia and Africa.
Environmental Sustainability: Innovative research in Biological Nitrification Inhibition (BNI) addresses nitrogen pollution and enhances nitrogen use efficiency in wheat, contributing to environmental sustainability.
Disease Resistance: Advanced breeding techniques are being employed to develop wheat varieties resistant to devastating diseases like wheat rust, protecting yields and ensuring food security.
“By combining cutting-edge AI and genetic diversity, we are future-proofing wheat to thrive in challenging environments,” said Professor Matthew Reynolds.
The session will take place during Plenary Session 4 on Tuesday, September 24, 2024, from 8:30 am to 8:50 am at the Perth Convention and Exhibition Centre.
About CIMMYT
CIMMYT is a cutting-edge, non-profit, international organization dedicated to solving tomorrow’s problems today. By fostering improved production systems for maize, wheat, and other cereals through applied agricultural science, CIMMYT enhances the livelihoods and resilience of millions of resource-poor farmers while working towards a productive, inclusive, and resilient agrifood system within planetary boundaries.
A new study by CIMMYT, published in Global Change Biology, reveals that ancient wild relatives of wheat, which have adapted to extreme environmental conditions for millions of years, could be key to securing our future food supply. These wild varieties offer valuable genetic traits that can help modern wheat resist diseases, build climate resilience, and reduce agricultural emissions, making them essential for adapting to increasingly challenging growing conditions.

Agricultural activities, particularly the production of cereal crops and major staple foods like maize, wheat, teff, barley, and sorghum, are vital to the livelihoods of rural communities in Ethiopia. For example, about 80% of agricultural operations in the Tigray region’s Adwa district are related to cereal production. However, this, as well as agriculture in general, is highly susceptible to the effects of climate variability and change, which have a direct influence on farming communities’ rural livelihoods.
With support from the Development Fund (DF), CIMMYT is collaborating with several partners to address the challenges caused by climate variability in agriculture through the implementation of Climate-Smart Agriculture (CSA) technologies and practices. Efforts are currently focused on the Folfolo and Lalay Logomti watersheds in Adwa, where CSA demonstration sites are being implemented through Ethiopia’s Climate Adaptation and Rural Development (CARD)-II Program.
On 2 August 2024, CIMMYT scientists and experts from CSA-implementing partners under the CARD-II program visited the CSA demonstration sites to observe the ongoing activities, interact with farmers, and share their thoughts on progress so far.
Rehabilitating the natural environment
Since 2021, CIMMYT and partners, including the Relief Society of Tigray (REST), iDE, Women Empowerment Action, ORDA-Ethiopia, and HELVETAS, have been implementing numerous CSA-related activities on hillsides, farmlands, homesteads, and gullies. These activities provide multiple benefits for farmers to ensure food and nutrition security and include the management of natural resources, such as creating an arboretum, constructing trenches, and planting indigenous trees and forage plants in the upper catchments. Lower catchments and farmlands are undergoing biological and physical reclamation of gullies and riverbanks, trench construction, percolation ponds, crop diversification, and homestead plantations.
Moti Jaleta, a CIMMYT agricultural economist coordinating the implementation of CSA activities under the CARD-II Program, was excited by the visit and the effort farmers and partners have put into rehabilitating the natural environment and degraded croplands. He was also impressed by the food and feed crop technologies farmers have integrated into the rehabilitation work, as well as the overall benefits farmers have witnessed from their efforts.
“It is crucial to understand that the benefits of CSA technologies often extend beyond boosting yields,” said CIMMYT systems agronomist Tesfaye Shiferaw, who passionately described the program’s successes so far. “For example, in smallholder farming systems facing terminal droughts, an improvement in soil moisture content that would extend crop growth duration by just ten days can mean the difference between a complete crop failure and a normal yield.”
“This underscores the vital role of CSA technologies, especially under challenging conditions,” he explained. “During our field visit to those sites, such anecdotes were repeatedly emphasized.”

Streams begin to flow
Farmer testimonies from the field attest to the numerous benefits of CSA practices. “This area was known for its high runoff and water erosion some years ago,” said Giday Hagos, a 70-year-old farmer from Folfolo village. “Producing crops and engaging in other agricultural pursuits seemed unimaginable. But following the intervention of the CSA, I was very excited when the streams at the mountain’s base began to flow, and I started farming immediately using the stream for supplementary irrigation.”
Hagos used to grow cereal crops, but he was excited to make use of the potential offered by CSA technologies and has now shifted to market-driven commodities. “Last year, I was able to generate an income of about ETB 90,000 (approx. $815) from the sale of onions,” he explained. “And this year, expanded the farming activities to other areas by renting additional plots.”
The program was designed to increase productivity, adaptation, and sustainability while enhancing resilience to climate shocks through mitigation. So far, the successes are numerous. Upper catchment hills have seen an increase in vegetation cover, degraded lands have undergone regeneration, water runoff has decreased, groundwater yield has increased, streams and springs are thriving, soil moisture and forage availability have increased, and farmers have diversified their crop and livestock production. These are just a few of the multiple effects of the CSA technologies and practices implemented at the watershed level by the local farming community, the Relief Society of Tigray (REST), the Ethiopian government, and other local partners. The adoption of CSA technologies has also provided greater opportunities to reduce the harmful effects of climate change on agriculture and improve rural livelihoods.

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.

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.

Maize productivity in eastern and southern Africa faces numerous challenges, including biotic and abiotic stresses, as well as socio-economic factors. To tackle these constraints, CIMMYT, in collaboration with partners, has been developing elite multiple stress-tolerant maize hybrids for different market segments. The hybrids are rigorously evaluated in research stations under managed stresses, especially those faced by farmers, including drought, heat, and low nitrogen. The process is complemented with evaluations conducted in actual farmer conditions through a participatory approach, which enables researchers to identify traits preferred by farmers.
Over the years, and through consistent engagement with farming communities, CIMMYT and partners have established a large on-farm testing network to allow farmers to test the best-performing hybrids within their own fields and management. This ensures that new varieties selected for commercialization suit the needs, constraints, and priorities of smallholder farmers.
Centrality of ROFT in the variety development process
Regional on-farm trials (ROFTs) are a crucial step towards maximizing the impact of breeding investments. ROFTs help scientists understand the performance of pipeline hybrids under diverse management conditions. The data and insights gathered from these trials, led by district leads, are instrumental in identifying the best varieties to release. In Zimbabwe, the extensive on-farm testing is conducted with support from Zimbabwe’s government extension arm, the Department of Agricultural, Technical, and Extension Services (Agritex), and selected seed companies.
To help track the progress or challenges in varietal performance evaluation at the farm level, CIMMYT has been convening feedback sessions with district agriculture extension officers (DAEOs) across 19 districts. These sessions have been instrumental in strengthening the collaboration with Agritex, standardizing data collection, and improving data quality and returns from the established on-farm testing network.

The ROFT trials have been ongoing in Zimbabwe for over a decade across 19 districts, located in natural regions I, II, and III. These trials have been implemented by more than 137 AEOs and have involved over 1,000 farmers. The network deliberately included a diverse range of farmers, with around 40% being female plot managers, to encompass a wide range of smallholder farming practices.
Participatory engagement is key
Every year, CIMMYT produces improved varieties that are then taken up by partners, including National Agricultural Research System (NARS) partners and seed companies. The on-farm trials aim to generate agronomic performance data in comparison to the widely grown commercial varieties and farmers’ own varieties. This data is used for a rigorous advancement process, where varieties that pass the test are then furthered for licensing and possible commercialization by CIMMYT’s partners.
Farmer involvement at the final stage of the variety selection process is key to the success of these trials. Farmers evaluate the varieties based on their specific needs, on their farms. This step is crucial as it empowers farmers to have a say in the variety development process. CIMMYT actively uses this participatory selection approach, seeking input from farmers and refining breeding targets as necessary. Farmers communicate their preferences and feedback through the farmer evaluation sheets, helping breeders fine-tune their targets and develop varieties that meet farmers’ needs.
Another key element of the on-farm trials is that they help assess breeding progress in farmers’ fields in terms of crop productivity and return on investment.
