As the conflict continues in Sudan, harshly disrupting agricultural extension communication and research linkages, Suliman Gadalla, a 55-year-old farmer from Shagarab West Village in Khasum Algrba Locality, Kassala State, eastern Sudan, feels proud that farmers in his village are eagerly asking him about the new sorghum variety he is growing on his farm. Gadalla is very satisfied with his experience using a chisel plough, growing certified seeds, and applying chemicals to control herbicides.
âEvery day, no fewer than 10 farmers visit my field to gain firsthand experience in using proper agricultural technologies and to learn more about the new sorghum varieties I am growing,â said Gadalla.
“When I learned about the new sorghum varieties grown on Sulimanâs farm and saw their good growth, I told myself I must follow what he is doing to understand the benefits of the new planting methods and wait until harvest to see the yield of the new varieties. If the trial is successful, I plan to get some seeds from my friend Suliman, either by purchasing or borrowing, and cultivate the new varieties next season on my farm,â said Hassan Rahamtalla, a 57-year-old farmer in West Shagarab Village in Khashum.
Under the aegis of the SASAS program, the USAID-funded SFSI was launched in May 2024 in response to Sudan’s food security challenges. SASAS partners strive to increase crop yields through the adoption of certified seeds and Quality Declared (QD) seeds of improved crop varieties.
Through farmers’ demonstration fields, SASAS partners CIMMYT and Harvest Investment Company LTD work extensively to accelerate the adoption of two newly released sorghum varieties, Butana and Dahab, and make their seeds available to communities through demonstration farms established in over ten villages across four localities in Kassala State.

âIn addition to inclusive agricultural advisory services, one expected outcome of the demonstration fields is to provide high-quality seeds of the new sorghum varieties, which will increase variety options for farmers and enhance seed system security through improved seed availability,â said Omar Ali, SASAS Seeds Systems Officer.
SASAS partners fully supported the cultivation of 60 feddans in Kassala State as demonstration farms to provide agricultural advisory services that deliver critical information on improved crops, soil, and water management to rural communities through extension, demonstration campaigns, and market linkages.
âThe knowledge and skills I gained from the on-farm training are amazing. We were given real experience in ploughing our lands using a chisel and disk harrow and learned how to treat our seeds against fungal diseases and insect pests,â said Hawa Adam, a 45-year-old female farmer from New Halfa, adding that learning how to use herbicides to control weeds was very useful.
âSupport from SASAS came at a critical time as the armed conflict spread into new areas across the country, reducing the areas allocated for improved seed production. Through the SFSI farmersâ demonstration fields, we are exposing farmers to new varieties and enabling them to produce high-quality seeds of these varieties so that we ensure seed availability for the next farming season,â said SASAS Program Chief of Party Abdelrahman Kheir.
Agricultural research in Sudan has shown that certified seeds sourced from foundation seeds increase the yield of sorghum by at least 40% compared to seeds obtained from farmers’ bags. Seed multiplication of sorghum under the proposed area (450 feddans) will produce a quantity of certified seeds with the potential to plant a significant area of sorghum for food and feed in the 2025 growing season.

Thatâs how much farmers have saved this century, through use of disease-resistant wheat varieties. Modern wheat can thank its âwild relativesâ â grassy cousins millions of years old and tested through extremes of earthâs climate â for most of its resistance genes.
Despite such remarkable achievements in wheat breeding, weâve only scratched the surface of the genetic potential in wheatâs wild relatives. With climate change intensifying and the rapid evolution and spread of pathogens â a new strain of fungus can circulate in the jet streamâitâs imperative that we increase investment in researching this largely untapped genetic diversity. Doing so could revolutionize wheat production, ensuring food security while dramatically reducing agricultureâs 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.
Whatâs 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 cousinsâ 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 wheatâs 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.
Rebecca Benson, a 30-year-old mother of three from Igurusi village in Mbeya, Tanzania, is living proof of how small efforts against food loss can significantly impact peopleâs lives. Her journey unfolded during a recent USAID field mission in Tanzania for CIMMYTâs Southern Africa Accelerated Innovation Delivery Initiative (AID-I) project when we visited a grain storage facility operated by the Igurusi Agricultural Marketing Cooperative Society (AMCOS). This local cooperative provides storage facilities and connects rice farmers to buyers, ensuring their produce is preserved and marketed efficiently. The warehouse stores over 1,000 tons of paddy, which is dried, stored, and ready for market.
As we toured the warehouse, we noticed that between the collection and storage of produce, small amounts of paddy had spilled onto the ground. Although this might seem like a minor oversight, it quickly became clear that what could have been discarded as waste was, for some, a valuable resource.
Turning Food Loss into Livelihood
A few meters away, we noticed Rebecca winnowing paddy. Intrigued by the picturesque scene of wind blowing away chaff, we approached her and soon discovered her remarkable story. Initially shy, Rebecca gradually opened up to us and shared her story of resilience and great inspiration. Four years ago, Rebecca left a comfortable life for one filled with struggle. She had been in an abusive marriage but decided to rebuild her life after an altercation with her husband almost turned fatal.
âHe would drink and become very violent. I had endured a lot but realized that he might one day kill me. I was very scared,â Rebecca narrated.
Starting life on her own and without access to her familyâs land, she struggled to continue her rice farming, facing the overwhelming costs of leasing land and maintaining a farm. As her situation worsened, she found it increasingly difficult to provide for her children.

In her quest for survival, Rebecca began collecting waste paddy from spillage at the AMCOS warehouse. Initially, after threshing, it was just enough for her family to feed on, but she soon realized she could sell some of the rice to generate income. With the cooperativeâs permission, she started collecting, cleaning, and selling the grains at Tsh 700 per kilogram. On average, Rebecca gathers over 20 kg of rice daily, which helps her pay rent, school fees, and feed her family. Although a tedious task to sift through the soil and rocks, Rebecca does it enthusiastically.
While she hopes to one day acquire land and return to farming, Rebecca remains grateful for the opportunity she has now. “It is hard work, and I want to improve my life and that of my children. I have not been able to save enough to lease land for farming, but that is my goal,â she said. The work also keeps her busy and has granted her independence from her abusive partner, allowing her to support her family on her own.
The Reality of Post-Harvest Grain Loss
In Sub-Saharan Africa, post-harvest grain loss amounts to millions of dollars in lost revenue and a reduction in food security due to inadequate storage facilities and improper handling during drying and transport. While AMCOS works hard to preserve crops and prevent large-scale food loss, the small quantities of spilled rice are an unavoidable consequence of handling large volumes. For Rebecca, however, these spilled grains represent a lifeline. Through her resourcefulness, she has turned what could have been wasted into an opportunity, providing her family with food and financial stability.

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.Â
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.Â
“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said.Â
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.Â
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). Â
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.Â
“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.Â
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.Â
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. Â
“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.Â
Vision for sustainability
Rajendraâs 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.Â

On Pemba Island, part of Tanzaniaâs 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 amaranthâa vegetable high in fiber, protein, and essential micronutrientsâare 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. âI discovered that I could produce my own seeds and amaranth flour,â she said. âThis opened up new opportunities for me to take control of my farming practices and increase my self-sufficiency.â
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. âIt takes three months to harvest seeds, so I must be patient and committed to nurturing healthy crops,â she said. âI must also be precise in caring for the seeds through harvesting, drying, tapping, and sifting.â
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.

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 regionâs 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 communitiesâ 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 Ethiopiaâs 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.
âIt is crucial to understand that the benefits of CSA technologies often extend beyond boosting yields,â said CIMMYT systems agronomist Tesfaye Shiferaw, who passionately described the program’s successes so far. âFor 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.â
âThis underscores the vital role of CSA technologies, especially under challenging conditions,â he explained. âDuring our field visit to those sites, such anecdotes were repeatedly emphasized.â

Streams begin to flow
Farmer testimonies from the field attest to the numerous benefits of CSA practices. âThis area was known for its high runoff and water erosion some years ago,â said Giday Hagos, a 70-year-old farmer from Folfolo village. âProducing 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 mountainâs base began to flow, and I started farming immediately using the stream for supplementary irrigation.â
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. âLast year, I was able to generate an income of about ETB 90,000 (approx. $815) from the sale of onions,â he explained. âAnd this year, expanded the farming activities to other areas by renting additional plots.â
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.

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 countryâs 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 farmersâ 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 Zambiaâs 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 âlet’s chatâ 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 alliesâincluding donors, governments, NGOs, and businessesâto 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 Zimbabweâs 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 farmersâ 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 CIMMYTâs 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 farmersâ fields in terms of crop productivity and return on investment.
Umm Zeina, a 40-year-old farmer living in El Nahal, in Sudanâs Gadarif State, was not happy with her yield, blaming the poor seeds and traditional techniques she was using. This was until she participated in the extensive seeds production training program organized by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).
âWe learned a lot on how to produce seeds and how to control the parasite Striga mixed with crops. The training draws our attention to the fact that the availability of quality seed is the foundation for food production and productivity. As traditional farmers, we had very poor information about the availability, characteristics, and prices of seed of improved varieties,â Umm Zeina stressed.
ICRISATâs extensive training attracted more than 350 (68 female) seed producer farmers from El Fashaga and El Nahal localities aimed at helping seed producers provide seeds of appropriate varieties for use by different categories of farmers. Farmers were also trained in better selection, treatment, and storage of seed from their own farms. The training also focused on the production of disease-free seeds to support agricultural productivity and success. The training helped to enhance farmersâ demand for improved seeds and eventually aimed to deliver improved seeds to more than 6000 farmers in El Fashaga, El Nahal and other neighboring localities.
This training was held as part of CIMMYTâs Sustainable Agrifood Systems Approach for Sudan (SASAS) program, which empowers farmers and herders to reduce the need for humanitarian assistance even in conflict-affected Sudan. In the context of the atrocious food crisis in Sudan, SASAS and partners work to ensure that farmers produce the quality seeds they need to enhance food production amid escalating conflict.
In El Fashaga and El Nahal localities, the seeds production training focused on sorghum, as this crop is widely adapted and drought tolerant as well as it is a staple crop to strengthen food security and contributes to agricultural diversity and economic growth in the regions where it is cultivated.
âDuring the training, we learnt a lot on how to choose the best seeds to produce improved seeds and how to choose the land, isolation area, and cleanliness to harvest. I was extremely interested to learn more about how to keep the seed to its purest form for replanting purposes and human or animal consumption,â said Tarig Hassan, a farmer living in El Nahal locality.
The seeds production training also aimed at maintaining seeds quality control through training and regulatory systems, and how to multiply and distribute seeds in a timely manner and at a price affordable for farmers. Farmers also learnt to use a revolving seed mechanism to make available seeds for many new seed producer farmers for the next season through farmer-to-farmer seeds distribution.
âThe seed production training is not only on how to produce quality seeds and protect loss of seeds, but also about the use of diversified seeds of sorghum, millet and ground nut that serve for both food and nutrition securityâ, said Gizaw Desta, Senior Scientist in ICRISAT.
SASASâs objective is to improve food security and access to income-generating opportunities through the adoption of sustainable agriculture practices and the promotion of agri-processing and post-harvest management. It focuses on supporting smallholder crop and livestock farmers to adapt their farming activities to climate change and abiotic pressures by diversifying their crops to further cushion themselves from climatic vagaries, reduce post-harvest loss, and improve market participation, and functionality. Women and youth are supported through training and agricultural and veterinary inputs to increase income generation activities and access to economic resources.
âAt SASAS, we strive to train farmers in basic farm seed production. This helps preserve and expand the diversity of the seed on which our food systems in Sudan rely. Considering the dire food security situation in the country, we fully encourage farmers to be engaged in seeds production to provide different and improved seed varieties,â said Abdelrahman Kheir, SASAS Chief of Party in Sudan.
SASAS works with ICRISAT to uplift smallholder farmers and ensure food security in semi-arid tropics. SASAS partners are committed to elevating crop productivity, resilience, and sustainability vital to dryland communities’ prosperity. This steadfast commitment profoundly affects millions in the world’s most challenging agricultural regions.
Science without policy is just academia; policy without science is just guesswork. Through a blend of robust field research and policy advocacy, CIMMYT aims to bridge the gap between policy and practice in promoting sustainable agricultural practices through crop diversification in South Asia.
Taking Bangladesh as an example, CIMMYTâs work in the country highlights the critical need to link research with policy to achieve sustainable agricultural practices, enhance food security, and improve farmer livelihoods.
The power of research-informed policy
Bangladesh’s agriculture is highly rice-centric; although rational, this is risky and arguably unsustainable. This means there needs to be a focus on crop diversification, which is one of the approaches toward sustainable agriculture that can address socioeconomic and environmental challenges.
Recognizing these challenges, CIMMYT has been at the forefront of developing solutions by conducting extensive multi-location on-site and on-farm trials that consider the socioeconomic and pedoclimatic dimensions of farm households.
Additionally, CIMMYT analyzes historical policies and initiatives that have been implemented by the Bangladeshi government and international partners to promote crop diversification. Several opportunities for improvement were identified in past policies and project implementation; addressing these challenges requires bridging the gap between policies and research to scale up crop diversification efforts.
Through the RUPANTAR and CGIAR Transforming Agrifood Systems in South Asia (TAFSSA) projects, CIMMYT-Bangladesh has developed an analytical tool to understand the political economy of crop diversification policies and practices. When applied to agriculture policy research, this tool can be tailored to any country and policy context in South Asia.
For example, while the government recognizes crop diversification in its agriculture policies starting with the Fifth Five-Year Plan, substantial funding for crop diversification efforts was only recently allocated. Integration of crop diversification into the government’s annual funding systems is essential to mainstream crop diversification in agriculture.
Many crop diversification policies and projects primarily focus on production, neglecting market systems development for new crops. Similarly, research suggests insufficient attention is paid to cold storage and other infrastructure needed to support diversification.
Most initiatives appear to have been project-driven, resulting in short-lived action without long-lasting impact. Insufficient coordination and support from government agencies appears to have affected projects led by both governments and development partners.
Stakeholder engagement spreads awareness
Without translating research into policy, we leave innovation on the shelf. CIMMYT-Bangladesh disseminates research findings to policymakers through the country Priority Investment Plan for the crop sector at the Bangladesh Agricultural Research Council (BARC), and South Asian Association for Regional Cooperation (SAARC) member countries through regional consultation workshops on accelerating the transformation process for sustainable and nutrition-sensitive food systems.
Looking ahead, CIMMYTâs efforts in South Asia remain dedicated to bridging the gap between research and policy. Ongoing projects aim to generate robust evidence, advocate for informed policy decisions, and foster partnerships across sectors. By continuing to lead in this space, CIMMYT strives to contribute to a more resilient agrifood system for South Asia.
Maize production in Kenya is a critical component of the country’s agriculture and food security. However, climate change poses a serious threat to its production. Changes in temperature and precipitation patterns can affect maize growth, reduce yields, and increase the incidence of pests and diseases.
Prolonged droughts and unpredictable rainfall can lead to crop failures, while extreme weather events can damage crops and infrastructure. As the climate continues to change, it is essential for Kenyan farmers to adopt resilient agricultural practices and more adapted seed products to safeguard maize production and ensure food security for the population.
For decades, seed companies as well as governments and donors have invested in maize hybrid breeding. Dozens of new hybrids have been made available to seed companies throughout East Africa for multiplication and distribution. These hybrids are designed and tested to outperform older hybrids in terms of yield under rainfed conditions, to include tolerance to drought and pests.
However, the potential impact of these investments has been hampered by the slow turnover of hybrids among farmers. Research has shown that, despite the availability of newer, higher-performing varieties, farmers tend to purchase older, less productive hybrids. The âturnover problemâ in Kenya has been described by CIMMYT researchers in a recent publication.[1]
One of the constraints responsible for the low turnover of varieties is a lack of information among farmers on the performance of the newer products. Despite advancements in the development of new seeds and the retail infrastructure to reach farmers, neither the public nor the private sector is generating and disseminating information on the performance of different maize seed products across various agroecologies. Farmers therefore have choice overload but lack objective information on relative seed performance required to make informed seed choices across seasons and growing conditions.
CIMMYT conducted a field experiment to shed light on the potential influence of seed-product performance information on farmersâ seed choices. The study involved aggregating and packaging farmer reported yield data for some seed products and presenting this to randomly selected farmers at the point of sale to assess whether the new information would influence their choice of products. The study was conducted in Kirinyaga and Embu counties where, like many parts of Kenya, farmers have access to a diverse range of maize seed products from seed companies which promise benefits like higher yields and improved resilience but lack objective information on their performance which could support their choices, including when to switch and to what.
The study was conducted in March 2024, at the onset of the long rain season. The research team collaborated with 36 local agro-dealers in five towns and surveyed over one thousand farmers.  Farmers were intercepted as they approached the agro-dealer outlets and briefed about the study. Upon consent, they were informed on the benefits of trying something new (experimenting with varieties) and were offered a voucher for one free bag of maize seed to encourage them to try a seed product new to them. They then were randomly assigned to two experimental groups: treatment and comparison. Participants in the treatment group were shown a chart containing product-specific yield data on maize hybrids grown in their counties (see the chart below). The chart contained farmer-reported yields from the previous yearâs long rain season aggregated at two levels: county average yield and the average yield of the top 25% of farmers who realized the highest yields. The latter demonstrated the actual potential of a seed product. They were asked that, if they wished, they could choose the voucher product for experimentation from the list but they were not required to. Participants in the comparison group were offered placebo information that would not affect their seed choice: they were given some fun facts about Kenya and agriculture in Kenya. We assess the effect of the information on the choice of the bag of seed they were buying with the voucher to experiment with.
Table 1: Product-specific performance information on maize seed products in Kirinyaga March-August 2023 *actual product names have been removed for this blog*
Before they made any purchases, the customers were asked about which maize seed they intended to buy. After purchase, they were interviewed again to find out which maize seeds they bought and how they had used the voucher.
What we found
Majority of the treatment farmers had a very positive evaluation of the information they received, indicating that they found it relevant and useful when making seed choice. Specifically, over 90% of them said that the information was trustworthy and easy to understand while about 80% said that the information was easy to recall. Over 80% of them disagreed that the list of varieties was too long to comprehend, the information on varieties was similar and hard to differentiate and that it was hard for them to choose a variety from the list.
This positive evaluation of the information is also reflected in their seed choices. Pre-purchases (before they entered the agrodealer store), farmers who were exposed to the performance information showed increased certainty in their choices and a higher inclination towards products listed in the product performance data, particularly the top-performing varieties. While 5% of the comparison farmers indicated that they did not know what to buy with their vouchers, only 2% of the treatment farmers suffered the same uncertainty. Such farmers relied mostly on agro-dealers to recommend a product they could experiment with.
As shown by the bar chat below, only 7% of comparison group farmers desired to use their vouchers on (or had an effective demand for) products which were the top two in the product performance lists. This increased to 27% among the information group farmers, representing an increase of 286% in the demand of top performing products.
However, although our intervention relaxed an essential constraint (product performance information) and increased the demand for some seed products, the actual purchases were subject to other constraints, stock-outs key among them. As a result, both groups showed shifts from initially desired products in their actual purchases. Even so, the treatment group maintained a stronger alignment with the listed products, exhibiting a higher likelihood of purchasing top-performing products. Only 5% of farmers in comparison group used their vouchers to purchase products which were top two in the product performance lists. This increased to 13% among farmers in the treatment group, representing a 160% increase in the likelihood of purchasing the best performing products in the lists.
Reflections
Slow varietal turnover among maize farmers in E. Africa is a pervasive problem and there is no one solution to it. This research shows that information on product performance can be an effective approach in bringing to the attention of farmers newer, more adapted and better yielding seed products. Dissemination of such information can be incorporated in extension programs, shared at the point of sale, shared through SMSs and WhatsApp messages, displayed in posters fixed in public places, etc.
The findings offer clear recommendations for future investments in seed systems development. These include the implementation of new product testing regimes to ensure quality and objectivity of performance data, testing what other information would be useful to farmers â beyond yield data, exploring new marketing options to reach farmers more effectively, and considering additional approaches to empower farmers with the knowledge they need to make informed decisions thus leading to improved agricultural productivity, resilience, and livelihoods.
In conflict-ridden Sudan, Gadarif State in Eastern Sudan is the most important region for sorghum production, with about 5-6 million feddan (5.18-6.22 acres) cultivated on an annual basis on large scale farms equipped with agricultural machinery. However, like the country, the state is covered with vertisols, clay-rich soils that shrink and swell with changes in moisture content, that become waterlogged and cannot be properly cultivated during rainy season.
To address the issue, technical experts from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) are mapping areas affected by waterlogging in two localities, namely El Fashaga and El Nahal, to identify the most suitable lands to establish large drainage implementing sites integrated with improved crop varieties of sorghum. This work is part of CIMMYTâs Sustainable Agrifood Systems Approach for Sudan (SASAS) program, which works with farmers and herders to reduce their need for humanitarian assistance in conflict-affected Sudan.
âTo address the issue of vertisols affected by water logging in Al Gadarif, the prominent agricultural region in Sudan, we used the map developed by ICRISAT in 2023 and consulted with local farmers to identify 100 hectares El Fashaga and El Nahal localities to improve drainage and avoid waterlogging,â said Gizaw Desta, senior scientist at ICRISAT.
Waterlogging is common on poorly drained soil or when heavy soil is compacted, preventing water from being drained away. This leaves no air spaces in the saturated soil, and plant roots literally drown. Waterlogging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death. In Gadarif state, 2.3 million hectares and 1.8 million hectares of vertisols are under high and moderate waterlogging conditions that impair crop production during the rainy season, leading to food insecurity if not reversed with appropriate agricultural practices.

âFor years, my farm has been flooded by water during the rainy season, and I cannot cultivate sorghum as plants die of water suffocationâ, said Ali Ahmed, a farmer from Al-Saeeda area of ââAl-Nahal locality who is affected by waterlogging. âAlternatively, we as farmers affected by waterlogging were forced to cultivate watermelon instead of our main staple food sorghum. This shift in the crops we cultivate is hardly affecting our income. Â I am glad that ICRISAT is working to establish drainage systems and address waterlogging within our lands.â
âAt SASAS, we strive to ensure that farmers have access to fertile lands and other agricultural inputs. We work with our partners to address all problems facing farmers including waterlogging to help farmers continue producing their staple food and cash crops,â said Abdelrahman Kheir, SASAS chief of party in Sudan.
In Colombia, maize is the most important cereal, integral to culture, tradition, and diet. In 2019, Colombia consumed 7.2 million tons of maize, a quarter of which was white-grain maize used for human food (the remainder was yellow-grain maize for animal feed, with a small portion for industrial uses). National production is concentrated in the departments of Meta, Tolima, CĂłrdoba, Huila, and Valle del Cauca. Native and creole maize varietiesâthe latter comprising farmer varieties of mixed native and other ancestriesâare grown for use in traditional dishes or for sale at local markets.
Due to climate change, socioeconomic pressures, and the out-migration of smallholder farmers seeking better livelihoods, native maize varieties and the unique genetic qualities those varieties embody are endangered. We aim to design strategies that benefit smallholders who wish to continue in agriculture and perhaps continue growing native varieties valued in their communities, fostering the conservation and production of native maize. CIMMYT in Mexico has already facilitated commercial linkages between chefs in Mexico City and tourist areas (for example, in the states of Oaxaca, YucatĂĄn, and the State of Mexico), sourcing blue maize landrace grain from farmers in mutually beneficial arrangements.
CIMMYT and local partners have launched an ambitious initiative to map and strengthen the value chain of native maize in the departments of Nariño, Cundinamarca, BoyacĂĄ, Valle del Cauca, and Putumayo to promote beneficial farmer-market linkages and better understand Colombiaâs maize value chain. Carried out under the Nature Positive Initiative of OneCGIAR, the project is documenting maize conservation, marketing, and consumption to design a critical path that strengthens the value chain of Colombian native maize and benefits agriculture and the economy of rural Colombian communities.
Most native maize varieties in Colombia are grown on small plots for home consumption, exchange, and the sale of surplus grain. âThe production is planned so that the percentage of sales is lower than consumption,â explains a farmer from Nariño. âMaize grain is sold in traditional markets, typically on Saturdays or Sundays, most often as fresh white and yellow corn.â
In such markets, farmers may also sell their grain to intermediaries, but only in the markets of Nariño is the sale of creole and native maize varieties acknowledged. Varieties include yellow Capia, white Capia, yellow Morocho, and Granizo, with Chulpe being less common. The grain purchased is used to prepare a variety of traditional dishes and beverages.
The most commonly grown varieties are intended for the market and probably the regional and urban cultural groups that consume them, such as in Guaitarilla, Nariño, where large crops of white maize are marketed through intermediaries and traders to satisfy demand.
âA variety that is not widely grown may become more prominent due to market changesâsuch as the rise of niche markets,â the research team notes. Good examples are the departments of Pasto, Nariño, and Cundinamarca, where maize is increasingly grown to meet demand from buyers of purple or colored maize.
We have already identified several possible niche markets for smallholder maize varieties:
Fair trade enterprises. They promote the commercialization of national products at fair prices for farmers, offering maize in various forms from regions such as BoyacĂĄ and Cundinamarca.
Restaurants. They use maize in traditional dishes, reinterpretations of Colombian cuisine, and culinary experiments.
Small-scale local intermediaries. Without a fixed physical space, they distribute products to end users and other businesses.

Significant challenges may hamper these and other possible market opportunities in the maize value chain. Farmers, for example, face high production costs, climate change losses, competition from neighboring countries, dependence on intermediaries for sales, and a lack of land. For their part, buyers struggle with obtaining consistent production volumes from farmers, lack storage infrastructure, and face postharvest pest and disease management challenges.
While they are compelled by the need to feed their families and, if possible, grow enough grain to sell for a profit, smallholder maize farmers have also expressed interest in preserving maize diversity and their cultural practices.
âWe are not interested in growing monocultures for marketing; we grow maize out of love to continue preserving it,â comments a farmer from Nariño. Another farmer adds: âI would grow or sell more if the production were aimed at protecting agrobiodiversity, food security, sovereignty, and preserving cultural practices.â

To understand how niche markets could influence the conservation and rescue of native and creole maize in Colombia and, at the same time, design a critical path that strengthens the value chain and promotes fair and efficient niche markets, CIMMYT and its partners are conducting focus group interviews and buyer-meets-seller events. The aim is to mitigate challenges highlighted by the actors and create beneficial conditions for farmers and consumers, promoting a better future for Colombian smallholder farmers.
We deeply thank CIMMYT partners in Colombia for their contributions to this work: Andrea Gomez, Andrea PinzĂłn, and Jeisson RodrĂguez.

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

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

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

This process could also be labelled as âscaling deepâ as it encourages farmers to move away from conventional agriculture technologies. Reciprocally, scientists have been learning from the experiences of farmers on the ground to understand what works and what needs improvement.
Inspired by the successes of his peers in Shamva, Hendrixious Zvomarima joined the program as a host farmer and saw a significant increase in yields and efficiency on his land.
âFor three years, I have devoted time to learn and practice what other farmers like Elphas Chinyanga were practicing. It has been 14 years since joining, and this has been the best decision I have made as it has improved my yields while boosting my familyâs food basket,â said Zvomarima.
The longevity and success of the initiative can be attributed to committed farmers like Mutize, Chinyanga, and Zvomarima, who have been part of the program since 2004 and are still executing the trials. Farmer commitment, progressive learning, and cultivating team spirit have been the success factors in implementing these trials. CIMMYT’s long-term advocacy and learning from the farmers has been key to a more sustainable, resilient, and empowered farming community.
