The Mexican Revolution was not the only transformative movement to emerge in Mexico. Another profound transformation began in the Mexican countryside, and today, far from guns, today it continues to drive a more peaceful and resilient society through the integration of science, innovation and ancestral knowledge.
In the 1960s, Mexico set a precedent for global agricultural change. Today, that movement has evolved into a sustainability approach that responds to today’s challenges: climate change, biodiversity loss and the need to ensure food security. Under CIMMYT’s leadership, the Hub model has established itself as a key tool for delivering scientific solutions to producers, strengthening resilient and sustainable agricultural systems.
At CIMMYT, we believe that ensuring food security means not only producing healthier food but also conserving natural resources such as soil and water and promoting the well-being of farmers and their communities. Through the Hub model, we have promoted practices such as the sustainable management of staple crops such as maize and related crops, and the use of strategies to strengthen the seed system to meet the challenges of the agricultural sector.
A clear example of this approach is the Maíz Criollo Kantunil group in Yucatán. Led by Edgar Miranda, this collective of eight families has adopted innovative practices such as regenerative agriculture, efficient water use and agroecological pest management. By linking with the Hub model, the group has been able to conserve native seeds, strengthen local agroecology and generate social and productive benefits for their community.
“Our main objective is that the next generations will have seeds available to meet their food needs,” said Edgar Miranda. “We work with sustainable practices that allow us to conserve our resources and produce healthy crops,” he added.
In addition to supporting producers, the Hub model fosters associativity and community participation, essential pillars for building inclusive and resilient food systems. These activities are in line with national initiatives such as strengthening production chains, but also reflect CIMMYT’s commitment to a global approach to sustainable development.
CIMMYT’s strategy in Mexico not only supports producers in transforming their agricultural systems, but also promotes strategic alliances with public and private actors. These collaborations strengthen the integration of scientific solutions and sustainable practices, stimulate innovation in rural communities, and promote resilience to the challenges of climate change. With an approach based on science, inclusiveness and continuous learning, CIMMYT continues to contribute to building a more equitable, sustainable and prosperous future for Mexico and the world.

In the heart of Mbire’s Ward 2 in Zimbabwe, Tichaona Makuwerere has earned the trust of his community, not just as a farmer but also as a resourceful problem-solver. His journey began with “piece jobs” — manual labor that barely made ends meet. From providing firewood and bricks to renting an ox-drawn cart, Tichaona’s days were filled with tough and gritty work. Occasionally, he crossed into Zambia to collect baobab fruit for sale, returning with livestockpesticides, which he traded locally.
However, stability remained elusive. Jobs were scarce, and community hiring often favored personal connections. Undeterred, Tichaona turned to self-employment in 2007, offering ox-drawn ripping services to farmers. His commitment didn’t go unnoticed. When the CGIAR Agroecology Initiative (AEI) came to Mbire, the community recognized Tichaona’s entrepreneurial spirit and nominated him as a service provider.
AE-I brings together farmers and stakeholders to address local challenges and develop practical solutions in Mbire and Murewa. Through Agroecological Living Landscapes (ALLs)—collaborative spaces for innovation—various stakeholders work to identify, co-design, test, and adopt agroecological practices. One challenge identified was that agroecology can be labor-intensive, highlighting the need to reduce labor demands by integrating mechanization for manual activities such as crop planting, manure transportation, and threshing. Partnering with private sector organizations like Kurima Machinery, AE-I provides farmers in Mbire and Murewa with the tools and training necessary to make mechanized services more accessible.
Equipped for success through training and support
Tichaona’s journey with AE-I began with intensive training at Gwebi College of Agriculture in Zimbabwe, where he learned the intricacies of machine operation, repair, and business management. The hands-on experience gave him the confidence he needed. “It was a turning point,” said Tichaona. “The training gave me skills that are hard to come by here. I learned how to run and sustain an agricultural service business.”
In addition, Kurima Machinery provided practical guidance and support when delivering his new equipment kit, which included a two-wheel tractor, trailer, grass cutter, chopper grinder, ripper, thresher, and basin digger. Although Tichaona had no prior experience with engines, his determination, along with Kurima’s ongoing virtual support, helped him develop the skills needed to operate and maintain the equipment.
Scaling up from oxen to efficient mechanization
The kit has dramatically transformed Tichaona’s way of working. Where he once struggled with oxen, the two-wheel tractor can now complete a three-hour task in just 30 minutes. This leap in efficiency has enabled him to expand his services beyond ripping and transportation. Tichaona now offers grass cutting, baling, grinding, threshing, and basin digging services.
Mechanization has not only streamlined his business but also significantly increased his clientele. Previously, he served around 50 clients per year; now, with the tractor, he supports over 200 annual clients, many of whom are repeat customers. In a region where animal feed is scarce during the dry season, Tichaona’s baling services have become especially valuable. Over the past year, he has produced more than 3,000 bales, even attracting safari operators who use the bales as bait for animals.
“Hatisi kumira kutsvaga mabasa” (We keep going forward and look for new jobs), Tichaona reflected with pride. In his drive to grow, he has further diversified his services to include grinding forest products such as Faidherbia albida, acacia, and Piliostigma thonningii pods, producing affordable livestock feed for farmers. He acquired these skills during livestock feed production training at the ALLs.
Mechanization has not only improved productivity but also mitigated environmental risks. Grass cutting and baling have curbed the practice of uncontrolled burning, which previously caused frequent veld fires in Mbire and Murehwa. In recognition of the project’s success in promoting sustainable land use, the Environmental Management Authority (EMA) has invested in additional service kits for other wards.

Strengthening Resilience Amid Climate Uncertainty
Tichaona’s services have become indispensable in a community grappling with erratic weather patterns and prolonged droughts. By baling grass, sorghum stalks, and crop residues, he enables farmers to store feed for their livestock, mitigating risks during drought seasons. The benefits extend beyond livestock care—his machinery has helped farmers expand cultivable areas despite a shrinking planting season.
Moreover, Tichaona has stepped up as a water carrier during the dry months. With wells drying up, villagers often dig makeshift wells in distant riverbeds. Using his tractor, Tichaona fetches water from the borehole for the community. His efforts free up time for farmers to focus on land preparation and other critical tasks, boosting their productivity.
Building a Lasting Legacy at the Community Level
Tichaona’s success has translated into significant improvements for his family. His increased income has allowed him to build a new home and purchase land in Guruve town. He has also invested in goats for his children as a form of social security. “Kudya kaviri kwaitonetsa, ikozvino takutodya uye atichatenderi kuti muenzi asvika abve pamba asina kudya (We could barely afford two meals a day, but now we eat more than four meals. We ensure that no visitor leaves without eating),” he shared.
His generosity extends beyond his family. Tichaona provides free transportation for vulnerable residents, including the elderly, and offers free grinding services to low-income families. These acts of kindness have solidified his reputation as a respected and valued member of the community.
A Model of Adaptability and Determination
Tichaona’s journey has not been without challenges. Mechanical issues, such as trailer body wear, brake replacements, and two-wheel tractor bearing failures, have tested his resourcefulness. He stocks essential spare parts, conducts regular maintenance, and leverages Kurima Machinery’s support network for troubleshooting and repairs. Collaborating with other AE-I operators, he shares tips and techniques for maintaining machinery, ensuring consistent and reliable services.
As his confidence and skills grow, Tichaona is planning to expand his offerings. He envisions adding oil pressing for sunflower and groundnut as well as peanut butter production. Already, he has invested in a grinding mill operated by his wife, allowing him to focus on field services. His ambitions extend to poultry farming, where he plans to use his chopper grinder to produce feed, incorporating local products into his supply chain.
“Ndine hurongwa hukuru” (I have bigger plans ahead), Tichaona said. He dreams of drilling a borehole to support horticultureproduction, a venture that would benefit not only his family but also nearby farmers by providing easier access to water. His ultimate goal is to establish a comprehensive agricultural service hub, offering everything from land preparation to livestock feed production, to strengthen the community’s resilience.
A Model for Agroecological Transformation
Tichaona’s story exemplifies the far-reaching impact of empowering local service providers in rural agriculture. Through the CGIAR Agroecology Initiative, he transformed from being a community handyman to a pioneering agricultural entrepreneur in Mbire. His contributions not only enhanced agricultural efficiency and overall life for himself and his community, but also offered a blueprint for sustainable development in agriculture. His story reminds us that when local expertise is supported and equipped, it can transform communities into models of resilience and sustainable growth.
The foundation for a Vision for Adapted Crops and Soil (VACS) is capacity building: to boost adoption of opportunity crops, for nutritional security, diverse and climate-resilient cropping systems, to build healthy soils, a cohort of researchers and professionals is being supported to improve opportunity crops in Africa. Launched in October 2024 in Nairobi, Kenya, the VACS Capacity Project aims to train scholars and professionals in the latest plant breeding technologies. Professor Julia Sibiya, VACS Capacity Project Lead at CIMMYT, elaborates on how the project aims to contribute to the promotion, development and delivery of improved “crops that nourish” people, and the planet.
As part of the VACS Capacity Project, 30 Master and PhD students will be mentored by prominent experts in plant breeding. What support will they receive?
The students will be exposed to the latest technologies in plant breeding but will also learn from their mentors to deliver the VACS vision on opportunity crops and healthy soils.
The project also includes training of 40 mid-careers professionals. We want them to master the latest technologies and be able to apply them to develop improved opportunity crop varieties that will be used by farmers.
For maximum and long-term impact, the CIMMYT Academy, with the support of the Sustainable Agrifood Systems program, is developing gender-aware mentoring and curriculum on a wide range of topics, to directly address priorities of the 70 scholars and professionals. Expertise is being sourced at institutions such as Iowa State University, CIMMYT and African universities for robust e-learning modules on the entire plant breeding pipeline and seed systems, with materials updated and designed for the African continent.
What gaps does the VACS Capacity Project aim to address?
Today, in Africa, very few plant breeders and scientists working on plant improvement are focusing on the opportunity crops identified by VACS, such as finger millet, bambara groundnut, and amaranth. Most breeders focus on the main staples. This is why we want to build a critical mass of scientists who work on opportunity crops that are vital for food security and nutrition under climate change.
Besides increasing the critical mass of researchers working on the opportunity crops, we also want to bring up-to-date the skills of professionals in the breeding sector, which is a sector where technologies are evolving very quickly. Most of the approaches to crop improvement used today differ greatly from approaches used ten years ago, hence the request by many professionals to upgrade their skills.
In addition to the long-term training fellowships for Master and PhD students, we will provide targeted skills training to professionals, with short-term placements between one and six months in institutions where they can learn cutting-edge techniques that they will apply to opportunity crops.
The project is also designed to build networks and communities of practice around these crops, so people can collaborate in breeding and scaling efforts that are requested by farmers and consider market intelligence for impact pathways. This is in addition to exchanging knowledge and germplasm.
How does this project differ from other plant breeding capacity building projects?
The difference is that we will place professionals into institutions where they will be provided with hands-on training. We will work with universities, international research institutes, and the private sector, including seed companies. This is like offering internships to mid-career professionals who want to upgrade their skills or learn new ones.
Our approach also includes mentorships for both scholars and professionals. Mentors will be recruited from all over the world to assist the fellows in various aspects of their research journey. Last but not least, we hope to see researchers working with farmers so they can learn from each other.
What are the expected outcomes of reaching a “critical mass of plant breeders”?
The objective is to have sufficient breeders to implement crop breeding programs designed for opportunity crops. We also want to encourage them to apply modern techniques to improve opportunity crops and, this way, to contribute to the development of more nutritious plants that are grown in healthy soils. As I mentioned earlier, besides empowering scientists themselves, we also aim to create the conditions for effective collaboration and partnerships for the successful delivery of improved opportunity crop varieties, and this delivery will be accelerated by reducing the breeding cycle. Overall, it will allow us to scale up efforts towards opportunity crops worldwide.
The Africa Dryland Crops Improvement Network (ADCIN) emphasizes capacity building as a cornerstone for sustainable development and agricultural innovation. By addressing both human and infrastructure development, ADCIN is empowering research institutions and individuals across Africa to enhance agricultural practices, strengthen food security, and improve livelihoods in dryland regions.
In 2023, ADCIN made significant strides toward these goals by investing $1 million to strengthen National Agricultural Research and Extension Systems (NARES). This initiative focused on enhancing human capacity and infrastructure, equipping researchers, students, and institutions to address the unique challenges of dryland agriculture. The funding supported 32 awardees from East and Southern Africa (ESA) and West and Central Africa (WCA), including 15 visiting scientists, 7 students, 4 group training sessions, and 6 infrastructure development projects.
In 2024, ADCIN organized multiple training sessions in Senegal, Ethiopia, Nigeria, and Kenya, targeting seed system development, business sustainability, crop production improvements, and advanced data management techniques. These capacity-building efforts promoted knowledge sharing, collaborative research, and best practices in seed systems, crop breeding, agronomy, and data analytics. Four group training sessions were held: two in Kenya and Ethiopia for the ESA region, and two in Senegal and Nigeria for the WCA region.
Strengthening Seed Companies and CBOs for Growth in Nigeria
ADCIN, in collaboration with Syngenta Foundation Nigeria, hosted a two-day capacity-building workshop for seed companies and community-based organizations (CBOs) in Kano, Nigeria, on September 4–5. Supported by partners such as CDA, IITA, ICRISAT, and NASC, the workshop aimed to enhance seed production and commercialization efforts while promoting AVISA crops like sorghum, pearl millet, groundnut, and cowpea.
The workshop attracted 30 participants, including 20 CBOs and 10 seed companies, who were trained in topics such as seed production best practices, post-harvest handling, and seed certification standards. Key outcomes included the implementation of modern innovations like e-certification and seed tracking technologies, designed to improve transparency and efficiency in the seed sector.

Participants were also introduced to the Farmers’ Hub concept, which offers smallholder farmers access to essential agricultural inputs, machinery, and market opportunities. Many participants expressed enthusiasm about using the Farmers’ Hub to expand their customer base and grow their businesses.
“The networking opportunities provided by this training have been invaluable. I’m looking forward to applying what I’ve learned and taking my business to the next level,” shared one participant.
The training is expected to have a lasting impact on seed quality and foster business growth in Nigeria. By equipping CBOs to transition into fully operational seed companies, ADCIN is advancing the sustainability of Nigeria’s seed industry. Participants are now better prepared to tackle challenges in seed production, marketing, and regulatory compliance, paving the way for a more resilient seed sector.
With the knowledge gained from the workshop, participants are now better prepared to address the challenges of seed production, marketing, and regulatory compliance, paving the way for a more resilient and robust seed industry in Nigeria.
Promoting Crop Improvement in Senegal
From August 20-27, 2024, more than 50 breeding and crop protection technicians from nine West and Central African countries gathered in Saly, Senegal for a comprehensive training session. The training, co-funded by the AVISA project and organized by CIMMYT in collaboration with National Agricultural Research and Extension Systems (NARES) from nine West and Central African countries, including Burkina Faso, Cameroon, Chad, Ghana, Mali, Niger, Nigeria, Togo, and Senegal, aimed to improve the efficiency of cowpea, groundnut, pearl millet, and sorghum breeding operations.
Participants gained hands-on experience in key areas such as seed trial management, electronic data collection, and genotyping. These skills are essential for improving crop varieties and making them more resilient to local conditions.
Field trips to Bambey, Senegal allowed participants to practice techniques such as setting up and managing seed trials, leaf sampling for genotyping, and electronic data collection using tablets making research more efficient and accurate.

“This training has given me new insights into how we can improve our breeding programs and provide better seeds for our farmers. The practical sessions were particularly helpful,” said a participant.
By enhancing technicians’ skills in trial management and data collection, the training is expected to improve field data accuracy and contribute to the development of climate-resilient crop varieties, directly addressing regional food security challenges.
Enhancing Seed Producers’ Skills in Ethiopia
ADCIN held a three-day workshop in Addis Ababa, Ethiopia, from July 30 to August 1, 2024, focusing on building the capacity of the country’s seed producers. Organized in collaboration with the Ethiopian Institute of Agricultural Research (EIAR) and supported by CIMMYT, the workshop aimed to strengthen Ethiopia’s seed producers by improving their skills in key areas such as seed health management, seed business management, variety maintenance, breeder seed production, and postharvest handling.
The training attracted 19 participants from both the public and private sectors, including seed companies, producer associations and research centers. The sessions provided critical insights into the management of seed-borne diseases such as mycotoxins and aflatoxins, which affect crops like sorghum, chickpea, beans, and finger millet. Participants learned how to incorporate seed health testing into Ethiopia’s national certification process, which will help ensure healthier seeds and increased crop productivity.

The seed business management session introduced participants to the Business Model Canvas (BMC), a framework for creating viable and demand-driven seed business models. By emphasizing sustainable practices in seed production, processing, and marketing, the training equipped participants with the tools they need to grow their seed businesses and contribute to Ethiopia’s growing agricultural sector.
The workshop also discussed the importance of variety maintenance and breeder seed production, focusing on the genetic integrity of improved varieties. The postharvest handling session focused on seed storage techniques and pest management, helping participants in maintaining seed quality after harvest.
“This workshop has really opened our eyes to new business strategies and how we can ensure that our seed businesses remain profitable and sustainable,” shared a representative from a local seed company.
Through this training, ADCIN is supporting Ethiopia’s seed producers in their efforts to improve seed quality and business sustainability, thereby contributing to the long-term growth of the seed industry.
Equipping Breeders with Advanced Data Management Skills in Kenya
ADCIN held a training on modern biometrics, quantitative genetics and data management in Nairobi, Kenya, from 10 to 14 June.This capacity-building initiative brought together 43 participants from nine Eastern and Southern African (ESA)countries, representing breeding leaders, data champions, and young breeders working on crops such as chickpea, finger millet, pearl millet, pigeonpea, and sorghum.

The training focused on data-driven decision-making in breeding programs and covered topics such asexperimental design, advanced data analysis using the CGIAR Breeding Analytical Pipeline, and managing genotype x environment (GxE) interactions. Participants learned about the Breeding Management System (BMS), quality control processes, and practical applications of the CGIAR Breeding Analytical Pipeline, which enhancedtheir ability to analyze large datasets and improve breeding accuracy across the CGIAR-NARES network.
A Holistic Approach to Capacity Development
These training programs are just a small part of ADCIN’s broader initiative to build capacity across Africa’s dryland regions. These efforts, which focus on critical areas such as seed production, crop improvement, business sustainability, and data management, are helping to develop resilient agricultural systems capable of withstanding the challenges of dryland agriculture. As ADCIN works to strengthen robust and sustainable seed industries, these capacity-building programs will play an important role in increasing food security and improving the livelihoods of communities inAfrica’s drylands.
The collaborative long-term experiments (LTEs) established by CIMMYT and Ambo University on the Guder Mano Mezemer campus, specifically at the Abebech Gobena Agricultural Research Center (Photo: CIMMYT)
A collaboration effort between CIMMYT and Ambo University has positioned CIMMYT as the national leader in implementing high-impact technologies to improve the quality and quantity of cereal crop production in Ethiopia. This partnership, established over three decades ago at national and regional levels, has become a vital element in driving innovations and advancements in the agricultural sector.
A recent field visit to the LTEs, which were established three years ago, at the Abebech Gobena Agricultural Research Center in Guder, West Shewa Zone of the Oromia Region, demonstrated the importance of collaboration between research and development partners. The LTEs were established to study three main climate-smart interventions: nutrient management (including organic, inorganic, and residue-based practices), crop rotation, and intercropping, over an extended period of time. The event highlighted CIMMYT’s ongoing efforts to improve Ethiopia’s agricultural production, particularly by testing agronomic practices that increase yields and enhance soil health through the use of different organic fertilizers along with inorganic fertilizer and proper cereal-legume rotation over the past two years at the center and in farmers’ fields.
Focus areas of research
Research will focus on developing the best combination of locally available organic inputs with inorganic fertilizer, together with appropriate cereal-legume rotation on LTE plots, to monitor yield and soil health parameters such as organic matter accumulation over time, improve resource use efficiency, and enhance soil health. The main crops involved are:
Maize (Zea Mays): Jibat variety
Wheat (Triticum aestivum): Wane variety
Teff (Eragrostis teff): Quncho variety
Legumes: Faba bean, soybean, haricot bean, and pigeon pea
The LTE sites have served as demonstration and learning platforms for local communities. The cropping system in the area has traditionally been dominated by continuous monocropping of cereals for decades. In response, this collaborative LTE initiative has introduced four legume crops into rotation and intercropping systems, three of which are new to the area. Some of these new crops have been well received by farmers, who have selected the most promising options to try on their fields as “baby trials,” with the LTE plots referred to as “mother trials.” These efforts have been accompanied by training and resources for farmers and extension workers.
Community engagement and outcomes
The initiative has involved 55 farmers from three villages, with a focus on optimizing crop yields and promoting sustainable agriculture. Dr. Tesfaye Sida, an Agronomist/Sustainable Agrifood Systems at CIMMYT, highlighted the importance of these trials in improving food security and soil health in the intervention areas. He added, “This streamlined client-based collaboration, based on capacity development and knowledge transfer, is helping us to drive the pathways for climate-resilient, sustainable, and inclusive agricultural development for food and nutrition security in Ethiopia.”

On September 23, 2024, a significant stakeholder gathering, including academic professionals, research and development partners, and farmers, as well as local government decision-makers, visited the trial sites to observe the research activities and progress at the Guder Mano Mezemer campus in Birbirsa village, where CIMMYT and Ambo University are conducting collaborative research. During the event, Dr. Gizachew Kebede, a soil scientist at CIMMYT, highlighted the dual focus of the research: crop rotation and soil nutrient management. “Despite farmers’ familiarity with crop rotation, they often face challenges in identifying the best companion crops and appropriate sequences. We are addressing this by rotating cereals such as maize, wheat, and teff with legumes such as soybean and pigeon pea, some of which are new to the system and likely to improve soil fertility and system resilience. The other fascinating part of the research is the testing of both organic and non-organic fertilizers, an intelligent approach to determining best practices for soil health and productivity, with a particular focus on understanding long-term effects, with plans extending for at least a decade. This kind of knowledge transfer is crucial to improving agricultural productivity and sustainability in the community, and we have seen great results from the trials so far.”
Dr. Tesfaye Shiferaw, an agronomist/Sustainable Agrifood Systems emphasizes the model. “Initially these were long-term experiments (LTEs), which mainly established the long-term impacts of interventions (nutrient management, crop rotation, intercropping, etc.) on climate change effects, productivity, and soil health. However, during the demonstrations of these LTEs, local farmers expressed interest in trying the agricultural technology/intervention/practice of their choice. We then added potential other technologies that could be options and allowed them to conduct their own mini-trials (called baby trials) to increase the number of alternatives. In this context, the LTEs can now be referred to as “mother trials.”
Research collaborators also echoed this sentiment. Dr. Nigusie Bekele, Director of Guder Mezemer Campus, highlighted Ambo University’s pride in hosting trials and major events related to their research collaboration with CIMMYT. He emphasized the university’s commitment to multidisciplinary research and service to the community, noting that their partnership with CIMMYT is instrumental in this regard, particularly in promoting productive, inclusive, and resilient food systems in Ethiopia. Dr. Nigusie described their joint action research and innovation efforts as transformative, benefiting not only the local community but also the wider Ethiopian population dependent on smallholder agriculture.

The introduction of soybean and pigeon pea in the intervention villages has generated considerable interest among farmers, leading to increased participation and positive results. Farmer Shelema Hirpasa from Tuke Kutaye District was enthusiastic about the exceptional performance of these new crops, noting a stark contrast with the traditional varieties he had previously grown. Highlighting the advantages of crop diversification, he said: “I have been involved in farming since my childhood but have never seen such performance in my crops.” This reflects the transformative impact of these new agricultural practices on local farming communities.

This interaction highlights the importance of knowledge sharing and engagement in agricultural research, as stakeholders learn about innovative practices and advances being implemented in the field. The gathering also reflects the commitment of the various partners in the initiative, showcasing their shared interest in advancing agricultural research and promoting food security through collaboration between CIMMYT and Ambo University.
Media coverage and future directions
The collaboration and field visits have drawn media attention, with coverage from outlets such as the Oromia Broadcasting Network (OBN). This initiative, implemented by CIMMYT and Ambo University with support from One CGIAR’s Excellence in Agronomy (EIA) and Ukama Ustawi initiatives, is paving the way for sustainable and resilient agricultural practices in Ethiopia.
Through continued partnership and innovation, CIMMYT and Ambo University are not only transforming agricultural practices in the region but also contributing to the broader goal of food and nutrition security throughout Ethiopia.
Crops struggling to grow in drought conditions, Bihar (Photo: Moben Ignatius/CIMMYT)
Agriculture is one of the sectors most affected by droughts, which can last for months or even years. In Bihar, where rain-fed agriculture is the primary source of livelihood for many, droughts can be devastating for rural farmers. The growing threat of climate change to crop production and farming practices calls for adopting alternative farming methods. In 2022-23, many districts in Bihar experienced drought conditions.
To better understand the impact of drought on crop production practices and farmers’ livelihoods, researchers from CSISA, a CIMMYT-led project, conducted a survey in Bihar during both the Kharif and Rabi seasons of 2022-23, the year of the drought. In the Kharif season, 518 farmers from 11 districts, 39 blocks, and 79 villages were surveyed, while 339 farmers participated in the Rabi season survey. The primary goal of this data collection was to assess the impact of drought on agricultural practices and provide evidence to guide policy and decision-making processes.
The survey collected data on 123 variables related to rice production, including land preparation, cropping patterns for 2022 and 2021, crop establishment methods, irrigation management, fertilizer application, and weed management. Farmers also shared their perceptions of how the drought had altered their rice production practices and affected their livelihoods compared to the previous year.
For many farmers, the experience of the drought was harsh. Magni Singh from East Champaran reflected on the challenges: “This year (2022), the drought hit us hard. I could only plant paddy on a small piece of land, but with no rain, there was not much harvest. Our fragmented land makes efficient irrigation almost impossible, and relying on rain feels like gambling with each season. Farming in these conditions is becoming increasingly unsustainable.”
Similarly, Shanti Devi of Banka shared her struggles: “The season started with drought, and we struggled to get water to the crops. By the time the rain came, it was too late – it came during the harvest and damaged the crop. I couldn’t afford fertilizers in time, which made things worse. Every year, it feels like we’re battling both nature and rising costs.”
This drought impact assessment by CSISA is also valuable for further research, particularly for comparing rice production practices between drought and non-drought years. Such comparisons can help researchers and policymakers develop effective drought mitigation strategies tailored to farmers’ needs.

MoU signing event between Nepal and Bangladesh seed companies (Photo: Sirish Shrestha/CIMMYT)
In August 2024, four Nepalese seed companies and six international seed companies from India, Bangladesh, Japan and Thailand signed a memorandum of understanding (MoU) for custom seed production of cereals and vegetables in Nepal, opening up game-changing economic opportunities in South Asia. This agreement will allow international seed companies to produce seed in a suitable agroecology in Nepal and export to international markets. To support this, the Government of Nepal has agreed to exempt variety registration for export-oriented custom seed production and expedite the process with added incentives to attract more international seed companies. This move aims to position Nepal as a future regional seed production hub.
The conference attracted over 150 participants from 11 countries, including Bangladesh, Ethiopia, India, Japan, Kenya, Nepal, Pakistan, Singapore, Switzerland, Thailand, and the USA, representing research centers, civil society organizations, private seed companies, and national agricultural research systems (NARS). The event was organized under the USAID’s Nepal Seed and Fertilizer (NSAF) project which aims to foster Nepal’s seed market systems through the enhancement of stakeholders’ capacity in seed research, quality seed production, as well as the creation of an enabling environment that links seed companies with input and output markets.
Enhancing seed market systems in South Asia
The MoU is expected to enhance the seed market system in the region, create new economic opportunities for Nepal, boost agricultural exports, and generate income for farmers. It will also facilitate the transfer of advanced seed technology and foster stronger partnerships between seed companies in the region and beyond. Mr. M Anis Ud Dowla, Board Chairman of Advanced Chemical Industries (ACI) Limited, one of the largest business conglomerates in Bangladesh, expressed optimism about the partnership, citing Nepal’s favorable conditions for producing seeds of cool-season crops and the potential benefits for farmers in Nepal and Bangladesh.
In addition, ACI signed MoUs with Gorkha Seed Company and SEAN Seed Service Center, for the production of cereals and vegetable seeds, demonstrating growing confidence in Nepal’s seed sector where CIMMYT and its partners played a key role to enhance the capacity of the seed stakeholders for the past several years. “About 10 or 12 years ago, I had the opportunity to interact with the seed stakeholders in Nepal and at that time the seed sector was not viable, and the role of the private sector was insignificant. Now, I am impressed to see such seed sector transformation initiatives in Nepal,” says Manesh Patel, President of Asia and Pacific Seed Association (APSA) while acknowledging the effort made by CIMMYT and other seed stakeholders. He added that “it is time for Nepalese private seed companies to become a member of APSA to leverage regional opportunities.”
Untapped potential
Nepal’s diverse agroecology, encompassing tropical, subtropical, and temperate environments, provides an ideal condition for seed production of cereals, fruits, and vegetables. However, this potential remains largely untapped due to limitations within the country’s formal seed sector. The informal system dominates, leaving farmers with insufficient access to quality seeds. In 2023, the formal sector only met 25% of the total 180,000 metric ton requirement for cereal seeds. Consequently, Nepal heavily relies on imported seeds, particularly hybrid varieties of rice and maize, costing nearly half a billion dollars annually when accounting for both cereal seeds and grain imports.
Several factors hinder the development of Nepal’s seed sector: limited availability of high-yielding varieties that are tolerant to major biotic and abiotic stresses; a lack of farmer awareness regarding quality certified seeds and modern technologies; inadequate infrastructure for improved storage and road access; vulnerability to climate change impacts; insufficient incentives for private sector investment; and limited human and institutional capacity across the seed value chain.
To tackle these challenges and seize opportunities, the Government of Nepal has outlined key interventions through the National Seed Policy, National Seed Vision, and Agricultural Development Strategy (ADS). These policies aim to create seed roadmaps and foster an enabling environment to attract private sector participation. Recently, the government of Nepal approved the issuance of research and development licenses to private seed companies, allowing them to develop and deploy new seed varieties. Collaborative efforts by the Nepal Agricultural Research Council (NARC), Seed Quality Control Center (SQCC), and CIMMYT under the USAID-supported Nepal Seed and Fertilizer (NSAF) project are also leading to local seed companies producing hybrid seeds for rice, maize, and vegetables across various districts. However, this is at budding stage, and it needs to be scaled up further.
The nexus of seed security and resilient agrifood systems
The interplay between seed security and resilient agrifood systems is crucial for enhancing food security, particularly amidst climate change and global challenges. This relationship underscores the importance of robust seed systems that can adapt to various stresses while ensuring sustainable food production. “Seed systems are complex networks involving farmers, seed companies, service providers, and authorities, all working together to ensure high-yielding and resilient seeds reach farmers’ fields as quickly as possible,” said Bram Govaerts, Director General of CIMMYT, while addressing conference participants. He further emphasized that demand-oriented and effective seed systems help to harness the benefits of crop improvement.
The conference brought together prominent figures from South Asia and beyond, who shared their insights. “A well-functioning seed system guarantees seed security for all farmers,” noted BM Prasanna, Director of the Global Maize Program at CIMMYT, during his keynote address. He highlighted the critical nexus between seed security and resilient agrifood systems, emphasizing the need for technical, organizational, and institutional innovations. Prasanna also called for continuous public-private-producer collaboration to develop and strengthen seed systems in the global south.
Linking global and regional seed industry practices to fit into local conditions
The Hon. Minister of Agriculture and Livestock Development of Nepal, Ram Nath Adhikari, inaugurated the conference, welcoming delegates and emphasizing the event’s significance to Nepal’s agricultural sector. Benu Prasad Prasai, Chief of SQCC, shared emerging trends in Nepal’s seed industry, highlighting efforts to engage the private sector and reduce seed import dependency. “We need to harmonize and link seed policies across South Asia and beyond to fully capture the benefits of plant breeding gains,” said Prasai, while emphasizing Nepal’s potential for seed business and investment. Dyutiman Choudhary, NSAF project lead, echoed these sentiments, emphasizing the importance of international and regional partnerships in developing a vibrant seed market. He highlighted the need for enabling seed policies and regulations that facilitate market system development.
The discussions resulted in high-level recommendations to further augment Nepal’s seed sector: strengthening public-private partnerships in research and development to transform Nepal’s seed industry into a viable, resilient, and sustainable seed system; collaboration with foreign counterparts for joint research and technology exchange is vital to strengthening Nepal’s seed R&D and promoting custom seed production; legal frameworks must be developed and executed to create an enabling environment that strengthens public and private sector seed R&D efforts.

Ethiopia’s agricultural and food production systems face significant challenges due to soil acidity. Approximately 41% of the country’s cultivated land is affected, with 28% of this area being highly acidic. Heavy rainfall and inherent soil properties are significant drivers of this, and practices like continuous residue removal greatly accelerate these conditions.

The resulting acidic soil conditions can severely limit the uptake of critical nutrients, leading to lower yields and poorer crop responses to inputs. As a result, Ethiopia’s soil acidity conditions constrain the production and productivity of the country’s main staple crops and compromise efforts to achieve national food security.To help address these problems, policymakers, technical experts, and development partners in Ethiopia have come together to advocate for innovative data-driven solutions to remediate acid soils to raise crop yields and promote sustainable economic growth.
“At a national workshop convened by CIMMYT and the One CGIAR initiative on Excellence in Agronomy on 29 July 2024 in Addis Ababa, experts from CGIAR, the Ministry of Agriculture (MoA), the Ethiopian Institute of Agricultural Research (EIAR), universities, regional research institutes, the national soil health task force, NGOs, and other key stakeholders gathered to discuss acid soil management in Ethiopia. Participants emphasized that proper management of soil acidity could increase fertilizer use efficiency from 20% to as much as 90%, depending on the initial acidity levels and specific nutrients involved.
Tackling soil acidity
“Acidic soils are complex and widespread, affecting millions of hectares of arable land in Ethiopia,” said Tesfaye Shiferaw, an agronomist with CIMMYT’s Sustainable Agrifood Systems program and regional lead for the One CGIAR initiative on Excellence in Agronomy. “We understand the situation well and have developed innovative solutions under the GAIA project to address the issue. The spatial targeting framework created within the project represents a significant breakthrough, which the MoA has incorporated into Ethiopia’s nationwide acid soil reclamation initiative.”
Feto Esimo, Director General of EIAR, highlighted, “Addressing soil acidity is critical for enhancing food security and economic development in Ethiopia. A few years ago, we appealed to partners to intensify their efforts in creating sustainable strategies with lasting impacts for future generations. We are now seeing the GAIA project’s ongoing efforts effectively addressing these issues and offering potential solutions.”
The GAIA project approach

Researchers on the GAIA project have been evaluating alternative approaches to managing soil acidity, with a particular focus on lime application. This method aims to reduce aluminum toxicity and improve the availability of essential nutrients such as phosphorus (P), calcium (Ca), magnesium (Mg), and potassium (K) in the soil. Additionally, liming decreases the solubility and leaching of heavy metals and offers benefits for legumes, such as increased microbial activity and enhanced biological nitrogen fixation. The GAIA team’s detailed evaluation includes core activities like spatial targeting to identify priority areas for liming, determining optimal lime application rates, and assessing profitability for specific crop types.
The primary goal in Ethiopia is to guide targeted investments for effective soil health reclamation and increased agricultural productivity through liming and enhanced nutrient management. The project aims to establish a strategic spatial targeting framework, serving as both a policy tool and a blueprint for soil health management. This framework is designed to optimize lime application, ensuring it is prioritized in areas where it can deliver the highest return on investment for farmers and the government. Project outcomes also include expanding this framework for broader application.
Major project outcomes in Ethiopia
The GAIA research team conducted an in-depth investigation into the interactions between lime and fertilizer, developed a workflow and an essential policy tool integrated into the Ethiopian National Soil Information System (NSIS), and presented evidence-based recommendations on acid soil remediation to national and regional policy forums. The following significant system-level accomplishments have resulted from CIMMYT and partners’ research-driven recommendations.
Firstly, the Ethiopian Ministry of Agriculture (MoA) recognizes the GAIA project’s model as a successful blueprint for implementing and scaling up acid soil remediation nationwide. The government has launched a plan to reclaim 300,000 hectares of acidic cropland in 2024–2025, targeting around 10% of affected areas identified through the spatial targeting framework. To support this initiative, 1.4 billion ETB (approximately 12 million USD) has been allocated to manage acidic agricultural land. Additionally, at the National Stakeholder Consultation Forum on Acid Soils held in Bonga town, South-Western Region, in April 2023, the Ethiopian government prioritized soil acidity as a key focus. Since then, the government has reinforced its commitment to soil health programs, incorporating lime as an essential input alongside improved seeds and fertilizer.
These storylines were highlighted in July 2024 during a national working group meeting aimed at streamlining acid soil management strategies across Ethiopia. The meeting, led by GAIA and EiA in collaboration with the MoA and supported by the One CGIAR initiative EiA, underscored the strategic progress made by the GAIA project in addressing soil acidity. According to Feto Esimo, Director General of the EIAR, these advancements signify a substantial improvement, promising a lasting impact beyond the current agricultural season. He expressed appreciation for the project’s achievements and advocated for its expansion to serve as a model for similar soil health programs across the country.
“Lime is the most widely used remedy, and its effectiveness in increasing yields when combined with fertilizer is well-documented,” noted Temesgen Desalegn, Director of Natural Resources Management Research at EIAR. “In this context,” he continued, “the GAIA project is timely, offering a multifaceted approach to soil health management, not limited to acid soils. The project’s model has been widely welcomed and could provide a comprehensive strategy for other soil health initiatives in Ethiopia.”

The national working group meeting reached a consensus on recognizing project outcomes that drive system-level impacts. This effort to build a strong consensus extends beyond Ethiopia; it reflects a broader continental trend, highlighted by the Africa Fertilizer and Soil Health Action Plan: 2024–2034. This plan emerged from the Africa Fertilizer and Soil Health Summit held in May 2024 in Nairobi, Kenya, under the theme ‘Listen to the Land,’ organized by the African Union.
The GAIA project, funded by the Bill & Melinda Gates Foundation (BMGF), supports large-scale rehabilitation of acid soils in East Africa through data-driven insights and evidence-based recommendations for decision-makers. Led by CIMMYT in collaboration with various partners across Ethiopia, Kenya, Rwanda, and Tanzania, the project works in partnership with the Excellence in Agronomy (EiA) initiative of the One CGIAR. In Ethiopia, GAIA is implemented in cooperation with the Ethiopian Institute of Agricultural Research (EIAR).
In parts of the conflict-ridden Sudan, including the eastern regions such as Kassala and Gadarif, rainfall is sparse and recurring droughts caused by climate change compound the issue. Consequently, perennial grasses that are supposed to grow back year after year are dramatically disappearing.
In addition, uncontrolled and heavy grazing in large areas in Sudan is also negatively affecting soil by increasing erosion, and cattle hooves can compact the soil, preventing plant roots from receiving enough oxygen, water, and nutrients.
Due to these factors, many pastoralist groups in east Sudan are seeking grazing resources outside their recognized tribal territory. A major problem for these groups has been the recurrent droughts and the deterioration of pasture areas, which has forced them to stay longer in areas with rich grazing, thus competing with other groups and leading to frictions and conflicts.
Livestock-Food Systems Development (LFSD) is a component of the Sustainable Agrifood Systems Approach for Sudan (SASAS), funded by USAID, focused on the dairy and meat subsector of the livestock sector. The LFSD aims to enhance the utilization of appropriate forage and feeding options through the demarcation of migratory routes to ease access to grazing, avoid conflicts, and reduce long-distance livestock travel impact on livestock health.
Along with partners, Practical Action and International Livestock Research Institute (ILRI), LFSD, is establishing a 50 km migratory route demarcation from Al Hindiiyya to Banqir in the Atbara River locality, Kassala State, East Sudan. These routes connect villages to public grazing land for livestock to pass through without impacting farmland.
The intervention also includes reseeding 1,000 feddans (around 420 hectares) of grazing lands and creating water ponds for animals during the rainy season. SASAS is also enhancing water harvesting by using a tractor to increase soil moisture. The two interventions were recommended by local communities and agriculture and animal resources authorities in Kassala state.
“As the rainy season is commencing, we started working with the local communities and reseeding the targeted areas in rural Kassala and River Atbara localities as recommended by the Ministry of Agriculture,” said Dr. Abdallah Osman, Project Manager, Practical Action.

“To ensure the best results, we used a mix of five high-quality seed types, all of which were recommended by the Kassala State Ministry of Agriculture,” Osman said.
The reseeding will serve 15 villages and enhance grazing lands for over 100,000 animals in the area. In addition, water storing capacity will be increased by constructing 15 large water ponds.
“For the past decades, our grazing lands had diminished gradually, and we face huge challenges in feeding our livestock, especially during dry seasons. In most cases, we had to buy costly fodder and water trucking,” said Ahmed Hassan, a community leader and a herder from River Atbara Locality, Kassala State. “We feel very proud to participate in reseeding the grazing lands in our areas, as this will increase grass yield and quality, enabling us to feed our animals better.”
The intervention also aims to rehabilitate animal migratory route demarcations to ease access to grazing, avoid conflicts, and reduce long-distance livestock travel impact on livestock health.
“As farmers, we suffer a lot from animals that cross into our agricultural fields and destroy our crops. We are relieved that reseeding will create more grazing lands for herders, and the demarcation of animal routes will help reduce the chronic seasonal conflicts between farmers and herders,” said Haw Osman, a farmer from Am Safri, Kassala Rural locality.
“At SASAS, we strive to ensure that herders have access to rich grazing lands. We work with our partners to address all problems linked to overgrazing, reseeding pasture lands, and treating the causes of conflict between herders and farmers. We involve local communities in creating clear animal migration routes away from farms and increasing water sources for animals through water harvesting projects,” said Abdelrahman Kheir, SASAS Chief of Party in Sudan.

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.
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.
“Every 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,” said Gadalla.
“When I learned about the new sorghum varieties grown on Suliman’s 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,” 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.

“In 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,” 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.
“The 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,” 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.
“Support 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 farmers’ 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,” 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.

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.
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 people’s lives. Her journey unfolded during a recent USAID field mission in Tanzania for CIMMYT’s 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.
“He would drink and become very violent. I had endured a lot but realized that he might one day kill me. I was very scared,” Rebecca narrated.
Starting life on her own and without access to her family’s 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 cooperative’s 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,” 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.
Moving from traditional to modern farming
Previously, Rajendra cultivated cereal crops using traditional methods which often led to food crises for his family. However, he has now shifted to cultivating various crops throughout the year using modern farming techniques on his 1.02 ha of land and an additional 2.71 ha which he has leased.
“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said.
Remarkable achievements in crop production
Last year, Rajendra cultivated rice on 3.72 ha, yielding 8.8 metric tons (t) worth NPR 250,000 (US $1,880.71). Similarly, he sold 3.8t of spring maize from 1.35 ha, earning NPR 110,000 (US $827.51). This year, he expanded maize cultivation to 2.03 ha, with an expected income of NPR 200,000 (US $1,504.57). His potato crop yielded 5.5t worth NPR 125,000 (US $940.35), with an additional 5.5t stored for future sale.
In addition to crops, Rajendra has established a pig farm, earning NPR 400,000 (US $3,009.13) in 2023 from selling pigs. He received a feed-making machine for pigs from NSAF, under its support to agribusiness Micro, Small and Medium Enterprises (MSMEs).
Embracing modern technology and techniques
Rajendra uses both organic and chemical fertilizers and follows improved farming techniques such as hybrid seeds, line sowing, and machinery use. He owns a mini tiller and rents other machinery as needed. This year, with support from NSAF, he used a drone to spray fertilizer on his spring maize, significantly reducing labor and time.
“I have viewed videos of drones spraying fertilizer but never imagined it happening on my spring maize land. As a demonstration, 0.57 ha was used for nano urea spraying. The task was completed within five minutes of the drone taking flight. Similarly, I was astonished to learn that a drone can cover 2.02 ha in a mere 20 minutes,” he shared.
Intercropping and future plans
Rajendra has also implemented intercropping, combining maize with legumes on a 0.10-hectare plot. “Spring maize-legume intercropping is productive and effective for farmers such as me. We can make a profit from legumes, as well as spring maize. I will continue using this practice in the future,” he said.
Financial investments and community impact
The profits from agriculture have helped Rajendra to manage his household comfortably. He can now provide education for his four children, manage household expenses, and also pay the loan that he had taken for his household expenses. In addition, he recently invested NPR 250,000 (US $1,880.71) to build a new pig shed. He also sells his produce in local markets at Joshipur, Kailali.
“I have travelled a long way from being a subsistence farmer to engaging in commercial farming. This shift from traditional to improved farming technologies has been made possible with the support of NSAF/CIMMYT. I am grateful for their assistance and encouragement,” Rajendra said.
Vision for sustainability
Rajendra’s story reflects his dedication and hard work. “I was working as a daily wage laborer in India, hoping to secure a promising future for my children. Today, I can achieve complete sustainability through agriculture and provide quality education and a better life for my children,” he shared.

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