CIMMYT has strengthened agricultural research and breeding programs in Zimbabwe by donating machinery to Gwebi College of Agriculture to modernize breeding efforts and enhance genetic gains. This support equips breeding stations with advanced tools, reduces field labor, and expands research opportunities, including for women in technical roles. By fostering research partnerships and developing high-yield, climate-resilient maize varieties, CIMMYT is driving innovation to combat pests, diseases, and climate challenges, ultimately improving smallholder farmers’ productivity and supporting Zimbabwe’s goal of increasing maize yields.
Time is of the essence, but we are not making the most of it in the fight against hunger. In 2015, world leaders agreed to set ambitious targets for addressing humanity’s most pressing concerns, which shaped the 2030 Agenda and became widely known as the Sustainable Development Goals (SDGs). We are only five years from 2030, but SDG 2 Zero Hunger has completely slipped through our fingers. In 2023, there were between 713 million and 757 million undernourished people in the world. The latest estimates point to an uncomfortable truth: hunger is on the rise, and we will not meet SDG 2 by the end of this decade.
The outlook is so bleak that 153 Nobel and World Food Prize recipients signed an open letter published on Jan. 14 calling on political and business leaders worldwide to seriously fund “moonshot” efforts to change our current trajectory and meet the food requirements of a global population of 9.7 billion people by 2050. The renowned signatories are sounding the alarm at the dawn of 2025 because it takes decades to reap the rewards of agricultural research and development programs, but also because yields of staple crops are stagnating or even declining around the world at a time when food production should increase between 50% to 70% over the next two decades to meet expected demand.
Joint 2024 World Food Prize Laureate and former U.S. Envoy for Global Food Security Cary Fowler coordinated the global appeal, which was discussed during a hearing with the US Senate Committee on Agriculture in Washington, D.C. The open letter published afterward listed the most promising scientific breakthroughs that should be prioritized to sustainably increase food production, including “improving photosynthesis in staple crops such as wheat and rice to optimize growth; developing cereals that can source nitrogen biologically and grow without fertilizer; as well as boosting research into hardy, nutrition-rich indigenous crops that have been largely overlooked for improvements.”
The good news is that we already have the platform of cutting-edge science to develop and scale up these innovations where they are most needed in Mexico and in nearly 90 countries where CIMMYT works with the support of an unrivalled network of international donors and local partners.
Increasing Wheat’s Ability to Capture, Use Sunlight
Varieties of wheat plants differ in their capacity to use sunlight to produce grain. The main goal of breeders is to increase wheat’s yield potential to harvest more grain sustainably and from the same area of arable land. At present, current breeding can increase wheat’s average yield potential by 1% annually, but it would be necessary to achieve average yield increases of at least 1.7% year after year to meet the expected demand by 2050. Research is focusing on photosynthesis in wheat spikes to boost yield potential. Spike photosynthesis adds on average 30% to grain yield of elite wheat lines developed at CIMMYT, but these gains can go as high as 60% in wheat’s wild relatives and landraces. The strategy is to tap into this underutilized potential to boost yields of modern wheat varieties that are also better adapted to a warming and drier world, and resistant to known and new pests and diseases. We wish to accelerate this research and are seeking a US$100 million investment in the platform.
Boosting Nitrogen Use Efficiency in Wheat
Wheat is the world’s largest nitrogen fertilizer consumer, which contributes significantly to greenhouse gas emissions and soil degradation. Groundbreaking research led by CIMMYT is increasing wheat’s ability to use nitrogen more efficiently, thereby reducing its dependency on nitrogen fertilizer by between 15% to 20%, depending on regional farming systems. Increased nitrogen use efficiency has been achieved after successfully transferring a natural ability to inhibit biological nitrification from wheat’s wild relatives to modern wheat varieties. Biological nitrification inhibition (BNI) is a natural process that provides wheat plants with a more sustained source of nitrogen available in the soil, thereby increasing their nitrogen use efficiency. BNI wheat is a game-changing innovation that will contribute to significantly reducing agriculture’s nitrogen footprint sustainably without compromising yields or grain quality. While the BNI research platform has received its first investment for wheat, an additional investment of US$30 million per crop would expand the platform to maize, millet, and sorghum.
Improving and Scaling Up ‘Opportunity Crops’
CIMMYT recently partnered with the United Nations Food and Agriculture Organization (FAO) to advance the global Vision for Adapted Crops and Soils (VACS) endorsed by the G7, which aims to sustainably increase the production of diverse, nutritious, and climate-adapted indigenous and traditional food crops grown on healthy soils. We have identified seven “opportunity crops,” including pearl millet, finger millet, pigeon pea, cowpea, mung bean, and amaranth, that can be grown sustainably and significantly improve nutrition and food security in sub-Saharan Africa. At present, the VACS partner network is working hard to develop new varieties of these opportunity crops and to build pathways for African farmers to access improved seeds and markets for their produce. The soil component of the VACS movement is underfunded, so we are looking for a US$500 million investment to launch a strong VACS Soils initiative.
A Parting Shot
Improved photosynthesis and increased nitrogen use efficiency in wheat, and nutrient-dense indigenous crops are exciting “moonshot” efforts already building resilient food systems that may help humanity avert a global food catastrophe in two decades’ time. But political will and available funding for agricultural research and development will ultimately determine if these and many more urgently needed scientific breakthroughs will reach their full potential in the fight against hunger in a more food insecure and unstable world.

“Five of us borrowed $100 from our Vikoba group and invested it in seed production. Not only did we repay the loan with interest, but we also made a profit,” says Skola Sichalwe, a member of an extraordinary group of women who are transforming their community in Ivuna Village, Momba District. Vikoba groups, grassroots savings and credit associations, operate as informal microfinance systems in rural communities, empowering members with access to small loans and promoting financial independence. These groups often provide a lifeline for women seeking financial stability and growth in rural areas. What began as small savings groups has blossomed into a powerful movement of women breaking barriers and creating a legacy of resilience, innovation, and success. These women—once skeptical about venturing into seed production—are now thriving entrepreneurs, producing quality sorghum seeds and inspiring others in their community to follow their lead. Their journey began with a chance encounter with Miss Zainab Hussein, a passionate seed producer and a youth champion. Her vision and mentorship planted the first seeds of change. “I used to think farming was just about survival,” says Pauline Martin. “But Zainab showed us that with the right knowledge and tools, farming can be a business; a way to change our lives.”
A leap of faith in seed production
Before venturing into the world of seed production, these women were members of Vikoba groups, pooling their savings to lend and borrow money. While this system was helpful for meeting immediate financial needs, it offered little opportunity for growth or long-term investment. Everything changed when Zainab Hussein, an experienced seed producer and youth champion, began attending their meetings. Zainab introduced the group to the potential of improved seeds and the opportunities in seed production. She explained how adopting high-quality sorghum seeds could significantly increase yields and profits, far exceeding the returns from what traditional grain farming could offer. Her visits became a game changer, sparking curiosity and inspiring action among the women. “Zainab’s dedication inspired us,” says Skola Sichalwe. “She didn’t just train us. She believed in us.” As a trainer, mentor, and role model, Zainab played a central role in their transformation. She guided the women through the complexities of seed production, teaching them essential planting techniques, helping them understand TOSCI regulations, and offering practical solutions to challenges they encountered along the way. “She showed us how seed production could not only improve yields but also become a profitable business,” recalls Pauline Martin.

Inspired by Zainab’s success, the women saw an opportunity to turn their savings into a sustainable investment. This journey was further supported by the establishment of Youth and Women Quality Centers (YWQCs) under the Center for Behavior Change Communication (CBCC) and the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA)project through CIMMYT. The AVISA project, led by CIMMYT, piloted the YWQC model to address key challenges faced by rural farmers, including limited access to quality seeds, market linkages, and knowledge on improved farming practices. These community-led centers serve as hubs that enhance last-mile seed access by working with seed companies and local producers, ensuring a consistent supply of quality seed. They also facilitate market linkages by connecting farmers with aggregators and off-takers, improving market access and profitability. Additionally, YWQCs provide capacity-building initiatives, equipping youth and women with training in farming practices, local seed production, and business skills. The model further promotes collective action by encouraging farmers to form associations, strengthening their bargaining power and collective marketing efforts. These centers became hubs of opportunity, providing essential infrastructure and resources such as access to certified seeds, extensive training, and advanced farming technologies such as the multi-crop thresher through a cost-sharing arrangement. This technology not only improved efficiency but also ensured the quality of processed seeds, increasing its market value. The project also facilitated crucial linkages between the women and certified seed producers, ensuring they had access to high-quality inputs for their production. In some cases, the project even helped them find markets for their seeds, closing the loop and creating a sustainable business model. And so, they began the journey of seed production, transforming not only their own lives but also their community.

With loans from their Vikoba groups, they purchased quality seeds and accessed the tools, training, and market linkages provided by the YWQCs. “For years, we saved money but didn’t know what to invest in,” says Halima Kajela. “Seed production gave us a clear opportunity to grow.”
Challenges: A Test of Determination
The journey wasn’t without hurdles. Rodents feasted on the carefully spaced sorghum seeds, a new planting method the women had to adopt for certification. “Broadcasting seeds was easier, but seed production required precise planting and spacing,” Halima explains. “This made it harder to protect the seeds from pests and animals.” Excessive rain washed away seedlings, requiring several rounds of replanting. Cattle from neighboring farms often invaded their fields, causing further damage. Adopting good agronomic practices such as proper spacing, timely weeding, and regular inspections was initially difficult for these women, who were unaccustomed to the disciplined approach required in seed production. Despite these setbacks, the women persevered. With Zainab’s guidance and support from the YWQCs, they implemented solutions like using seed planters which saved time and effort during planting, knapsack sprayers helped combat pests and diseases, and multi-crop threshers simplified the post-harvest process. All these tools saved time and improved efficiency.
Triumph in the fields
And their hard work paid off. In their very first season, the women achieved remarkable success, producing three tons of TARISOR 2, an improved sorghum variety. This achievement not only set them apart from other first-time producers in the district, but also marked the beginning of a transformative journey.

The impact of their efforts went far beyond the impressive harvest. Ten women became officially registered seed producers with the Tanzania Official Seed Certification Institute (TOSCI), gaining recognition and credibility in the seed production business. Two members received specialized training in seed and fertilizer dealership, equipping them to expand their services and outreach to the community. Four women ventured into distributing essential agricultural inputs, such as maize seeds and hermetic bags, further diversifying their income streams and supporting local farmers. Recognizing the need for efficient post-harvest processing, the group collectively contributed to the purchase of a multi-crop thresher. This crucial investment significantly streamlined their operations, reducing labor and ensuring higher-quality processed seeds. Their efforts quickly translated into financial rewards. Within a short time, they sold one ton of their high-quality seeds, earning over $700. As word of their success spread, demand for their seeds continued to grow, promising even greater opportunities in the seasons ahead.
A ripple effect of change
Their success has had a profound effect on their community. The women’s achievements have earned them respect, and their influence is inspiring others to follow in their footsteps. “Before this, I didn’t believe in seed production,” says Pauline. “But after seeing Zainab’s success and what we achieved, even my husband now supports me fully in this venture.” Their impact extends beyond their fields. Other Vikoba groups have invited them to share their knowledge on seed production, and 10 new women have expressed interest in joining the initiative. By making improved sorghum varieties more accessible, they’ve also helped increase production and reduce food insecurity in their village.
Looking ahead: Planting seeds for the future
Inspired by their success, the women have ambitious plans. With a clear vision for the future, they are determined to expand their seed production enterprise and bring its benefits to a wider community. One of their primary goals is to extend their production to neighboring wards, such as Mkomba. To make their knowledge and improved seed varieties more accessible, they plan to establish demonstration plots closer to the village center. These plots will serve as practical learning sites, allowing more farmers to experience the advantages of using certified seeds and adopting best practices. “The demand for quality seeds is growing,” says Halima Kajela, one of the group members. “We’re committed to meeting that demand and helping more farmers improve their yields.” They are also exploring ways to diversify their operations. They aim to invest in distributing other agricultural inputs and post-harvest services such as threshing, to support farmers in the community and generate additional income. For these women, seed production isn’t just a business—it’s a symbol of empowerment.

Kenyan farmers continue to face significant challenges in accessing quality seed, particularly for dryland crops. To address this, Kenya introduced the Standard Certified Seed (SCS) class as a strategic initiative to bridge the gap between fully certified seed and informal farmer-saved seed, as semi-formal seed classes such as quality-declared seed are not legally recognized.
Officially launched in 2020, the SCS class offers a unique opportunity and has the potential to transform the seed sector for open-pollinated and vegetatively propagated crops, including indigenous vegetables, by ensuring quality while making seed production and certification more accessible and affordable. During a recent panel discussion, Lilian Gichuru, Seed Systems Specialist for Eastern and Southern Africa for the Dryland Crops Program at CIMMYT, highlighted its importance. She asked a critical question: “How can we leverage the opportunity presented by standard seed to ensure the delivery of quality seed to farmers, especially in underserved areas?”
This was the focus of a session on sustainable seed delivery systems at the Seed Trade Association of Kenya (STAK) Congress & Expo, held in Nairobi on November 6 and 7, 2024. Themed “Leveraging Technologies That Strengthen Agricultural Resilience and Climate-Smart Seed Systems,” the event served as a platform for knowledge-sharing, collaboration, and innovation. CIMMYT participated as one of the sponsors of the Congress.
To set the stage for the panel discussion, Ephraim Wachira, Deputy Director for Seed Certification at the Kenya Plant Health Inspectorate Service (KEPHIS), provided an overview of the SCS and highlighted Kenya’s efforts to implement its certification process. He described initiatives such as awareness meetings for seed merchants, training programs for outgrowers on certification processes, seed production and agronomic practices, and field inspections to ensure quality compliance. KEPHIS conducted field inspections, sampling, and laboratory testing to ensure quality compliance for 106 metric tons of seed—including sorghum, green gram, and cowpea—during a pilot phase, with a portion of the seed certified and labeled.
Despite these achievements, challenges persist. Limited farmer knowledge, dispersed farms, high production costs, and the impacts of climate change—such as the need for irrigation solutions—continue to pose obstacles. Slow adoption by mainstream seed companies and technical difficulties with online certification systems also hinder progress. However, opportunities lie in increased funding for climate-smart crops, government support for dryland agriculture, and growing farmer awareness. Wachira emphasized the importance of stakeholder engagement, saying, “Collaboration and stakeholder engagement are critical to ensuring farmers access high-quality seeds and advancing Kenya’s food security goals.”
The panel discussion provided valuable insights from Ephraim Wachira, Mutheu Ngila of Dryland Seeds, Thomas Kariuki, Head of Seed Production at Simlaw Seed, and Mulemia Maina, Managing Director of Agri Experience. Lilian Gichuru moderated the session and guided the conversation as the panel unpacked the concept of standard seed and evaluated its impact and progress.
Panelists emphasized that the standard certified seed class relaxes certain certification requirements, such as reducing the number of field inspections, lowering isolation distances, and adjusting allowable off-types. This adjustment is made without compromising essential quality standards, including disease tolerance limits, which are largely unaffected by the standard seed class protocols. The standard seed class remains a certified seed class.
“The concept of standard seed came from the realization that many farmers rely on farm-saved seed, which is often of unknown quality,” said Wachira. “Standard seed provides an option that improves seed quality while making production and certification of these important crops more practical and affordable.”
Despite its potential, the adoption of SCS faces significant challenges. One key issue is the high cost of production. “Production costs remain high, limiting the price advantage of standard seed. Seed companies often need to operate across multiple locations to meet certification standards, which drives up costs,” explained Mutheu Ngila of Dryland Seeds.
Another issue is low farmer awareness of the availability of certified standard seed for dryland crops—this lack of awareness has slowed adoption. “Farmers need to know that standard seed is a better option than farmer-saved seed in terms of quality,” said Gichuru. Without sufficient awareness, farmers continue to rely on informal systems, which are often less reliable and can introduce disease.
Logistics are another major challenge. Wachira noted, “Many standard growers register plots of less than one acre in scattered locations, making efficient inspections difficult. The small and dispersed production areas drive up costs and complicate the inspection process.” However, this challenge creates an opportunity for private inspection services to serve these remote plots.
The limited commitment of seed companies to this class of seeds remains an obstacle. Many companies have hesitated to invest in standard certified seed production due to concerns about profitability and the need for clearer differentiation in price and quality.
The panelists outlined several solutions to overcome these challenges and identified opportunities to scale standard certified seed.
One promising strategy is community-based production and certification. Mulemia Maina of Agri Experience emphasized the importance of localizing seed production. “Localizing seed production can save farmers significant costs. Transporting seed from distant regions is expensive, but if farmers can access seed locally, it becomes much more affordable.” In addition, localizing field inspections could lower costs and increase efficiency. “KEPHIS is ready to train more private community inspectors and district inspectors to manage this category of seed,” Wachira explained. This model could enable private companies to engage more farmers and improve the efficiency of certification.
Another opportunity is the growing emphasis on climate-resilient crops. Donors and government initiatives are increasingly prioritizing crops such as sorghum, millet, and pigeon pea that thrive in dryland conditions. These efforts align with the goal of scaling up the production of standard seed.
Raising awareness among farmers about the benefits of standard seed is critical to encouraging adoption. Thomas Kariuki, Head of Seed Production at Simlaw Seed, noted that creating more capacity-building programs for farmers would help them understand their role and expectations in seed multiplication. “We also need to engage consumers to understand the quality and value of standard seed to protect market potential,” he added.
To successfully scale up standard certified seed, all stakeholders—government, private sector, and donors—must work together to address challenges and leverage opportunities.
The private sector plays a critical role in driving adoption. Kariuki stressed the importance of incentivizing seed companies to engage in the production of standard seed. “Balancing affordability, accessibility, and quality is critical,” he said. “This is how we ensure farmers benefit while seed companies remain viable.”
Capacity building is essential to train seed companies, inspectors, and farmers on the production, certification, and benefits of this class of seed. In addition, regulatory adjustments should be made to facilitate the certification process. For example, the introduction of specialized inspectors for field inspections could eliminate the need for companies to use KEPHIS inspectors.
Developing markets for dryland crops is also vital to stimulate demand and encourage seed production. Finally, promoting collaboration among stakeholders will ensure the alignment of policies and resources.
Kenya is a world leader in standard seed certification, having developed robust protocols and standards that ensure quality without imposing prohibitive costs. Other countries are exploring similar models, but Kenya’s success could serve as a blueprint for others in Africa.

As Gichuru reflected, “Standard seed represents an opportunity to transform Kenya’s seed sector. But it will take collective effort, patience, and continued investment in awareness and capacity building to realize its full potential.”
Mutheu echoed this sentiment, emphasizing the importance of balancing quality, affordability, and accessibility: “Balancing affordability, accessibility, and quality is critical. This is how we ensure that farmers benefit while seed companies remain viable.”
As Wachira concluded, “Standard certified seed is about giving farmers a better option—one that is affordable, accessible, and of high quality. Let’s bring these benefits to the farmers who need them most.”
A handful of azolla (Photo: Telma Sibanda, CIMMYT)
Often referred to as “green gold,” Azolla is a small, free-floating and fast-growing aquatic fern with immense potential in driving towards agriculture sustainability. Thriving in waterlogged environments, this hardy plant forms a symbiotic relationship with nitrogen-fixing cyanobacteria, making it a natural fertilizer for crops like rice. Rich in protein, Azolla is also an affordable, eco-friendly feed for livestock and fish, reducing reliance on commercial alternatives. Its rapid growth and carbon sequestration capabilities contribute to climate resilience and resource efficiency. The water in the pond is enriched with nitrogen and can be used to irrigate plants/crops, increasing its value to farmers. Farmers in low-income regions are embracing Azolla as a game-changer, unlocking opportunities to boost productivity, improve soil health, and transition toward more sustainable farming practices.
Recognizing Azolla’s potential, the CGIAR-funded Transformational Agroecology across Food, Land, and Water Systems Initiative, also known as the Agroecology Initiative (AEI) in Zimbabwe, is integrating it into agroecological approaches in Murehwa. This initiative, which operates through five work packages (WPs), is reimagining farming systems by combining innovative business models (WP3) with agroecological technologies (WP1).

In one of the districts in Murehwa, AEI Zimbabwe selected poultry business model working in collaboration with Hamara Chicks, focusing on resilient and dual-purpose Sasso chickens. Known for their resistance and ability to free-range, these chickens provide both meat and eggs, offering farmers diversified income streams. Hamara Chicks implemented a two-stage model: first the brooding stage, where farmers raise chicks up to four weeks old and then sell them to other farmers who raise them from juveniles to maturity. While promising, the first cycle faced challenges, including a lack of affordable, nutritious feed, and difficulties in securing a market post-brooding and after maturity. To address these issues, WP1 and WP3 identified Azolla as a potential supplemental or alternative feed to support the poultry business model.
The dilemma of Azolla: Two sides of the coin
Azolla farming offers a compelling mix of benefits for sustainable agriculture. Environmentally friendly and resource-efficient, Azolla farming requires minimal land, water, and inputs, making it particularly suitable for small-scale farmers seeking cost-effective solutions. Its rapid growth is one of its standout attributes; under optimal conditions, Azolla can double its biomass in just 3-5 days. This rapid growth allows farmers to produce significant quantities of forage with limited investment, significantly reducing feed costs and increasing overall profitability. Its ability to be harvested daily ensures a consistent and reliable feed supply.
Nutritionally, Azolla is a powerhouse. With a protein content of 25-30% (dry weight), it is packed with essential amino acids, vitamins such as A, B12, and beta-carotene, and essential minerals. When incorporated into livestock and poultry diets, Azolla contributes to improved health, faster growth rates, and better production results. For smallholder poultry farmers, these benefits translate into tangible gains in meat and egg production, providing a pathway to higher incomes. Moreover, Azolla’s agricultural utility extends beyond animal feed. Its nitrogen-fixing capability enriches soil fertility, reducing reliance on synthetic fertilizers and supporting sustainable crop production systems.
However, as promising as Azolla is, its cultivation is not without challenges. Water availability is a critical requirement, posing a potential barrier in regions with limited water resources. In Murehwa, Zimbabwe, where the CGIAR-funded Transformational Agroecology Initiative is promoting Azolla, horticulture farmers already have access to reliable water sources, alleviating this concern.
Another challenge is the maintenance of Azolla ponds. To thrive, Azolla requires well-managed conditions, including optimal pH levels and nutrient balance. Poorly maintained ponds can compromise growth and productivity. Recognizing this, farmers participating in the initiative have received extensive hands-on training to effectively manage and sustain these conditions effectively, ensuring that Azolla remains a viable and productive resource.
Empowering farmers through training and capacity building
The initiative partnered with KDV Consultancy to train 70 farmers, including 40 women in Murehwa, equipping them with essential skills for Azolla cultivation. The training sessions focused on pond construction, maintenance, and integration of Azolla into poultry feeding systems. This hands-on approach ensures that farmers can sustainably enhance their poultry value chains.

By co-designing solutions with farmers, the initiative prioritizes their needs and challenges, and promotes practical, farmer-driven outcomes. Empowering farmers with the knowledge and tools to implement sustainable practices not only strengthens their resilience but also enhances the long-term sustainability of poultry production in Murehwa. This collaborative effort is laying the groundwork for a more robust and adaptive agricultural future.
The integration of Azolla farming represents a promising step towards achieving a more sustainable and resilient agricultural system in Murehwa. By addressing the feed challenges faced by poultry farmers, Azolla not only enhances poultry production but also contributes to the broader goals of food security and economic stability in the region. As the Transformational Agroecology across Food, Land, and Water Systems project progresses, the positive impacts of innovative practices like Azolla farming continue to support the well-being and livelihoods of farmers in Murehwa.

Ethiopia faces increasing challenges from climate change, including erratic rainfall, soil erosion and longer dry seasons. With a rapidly growing population of more than 120 million, the country’s agricultural systems and natural resources are under considerable pressure. To address these challenges, the Scaling Conservation Agriculture-based Sustainable Intensification (SCASI) project, launched in March 2022 and implemented by CIMMYT and CFGB networks with the financial support from the Development Fund of Norway, offers a promising solution. SCASI integrates Conservation Agriculture-based Sustainable Intensification (CASI) practices to improve productivity while conserving natural resources.
The SCASI initiative is an exemplary model of how holistic agricultural approaches can enhance crop productivity, improve soil health, and build resilience to climate change in Ethiopia. Here’s an overview of the project’s key components and impacts.
Key components of CASI
CASI is a comprehensive production system in which conservation agriculture (minimum tillage, covering the soil surface with mulch and use of cereals and legumes in the form of intercropping or crop rotation) is combined with improved seeds, application of recommended organic and inorganic fertilizers, use of best management practices (recommended seed rate, timely weeding, proactive pest management, etc.) to increase productivity per unit area while improving the health of the production environment (soil, climate, fauna and flora and biodiversity). CASI also includes practices that help optimize the mixed crop-livestock systems by reducing the competition for crop residues through the promotion of alternative fodder crops, alley cropping, agroforestry and other locally adapted innovations.
Implementation across Ethiopia
Targeted Regions: The initiative was implemented in eight districts in the Amhara, Oromia, Benishangul-Gumuz, and South Ethiopia regions, each with unique agricultural contexts.
Direct Impact: Approximately 15,000 households (more than 75,000 smallholder farmers) have directly benefited, been capacitated, and gained access to sustainable practices that improved their productivity and livelihoods.
Partnership: Creates a unique partnership between national institutions, international organizations, and NGOs to support and strengthen national capacity to demonstrate and scale up CASI practices. Implements a collaborative and inclusive process in which partners contribute based on their expertise, capacity, and thematic focus.
How do we implement SCASI?

The SCASI project uses an approach that integrates collaborative partnerships, with CIMMYT leading action research, the Ministry of Agriculture and regional offices aligning policy, and NGOs (CFGB, FHE, TDA, MSCFSO) engaging communities. It is supported by a comprehensive implementation framework that includes large-scale demonstrations to illustrate the benefits of CASI, action research to adapt practices to local needs, and capacity building to empower farmers and stakeholders for sustainable adoption and scalability.
CIMMYT’s researchers, provide action research findings that highlight the multifaceted approach of the SCASI initiative, which focuses on context-specific solutions to improve agricultural productivity and sustainability in Ethiopia. Birhan Abdulkadir, SCASI project leader and agronomist at CIMMYT, said, “We conducted a comprehensive participatory assessment to identify the major production constraints in the 40 kebeles and developed site-specific packages from the combinations of CASI practices. These were implemented in mega demonstrations on host farmers plots with close support from CGFB networks and BoAs. We facilitated access to inputs and provided technical backstopping.”
The project also uses farmer-centered approaches to promote the practices. Host farmers train other farmers and share knowledge and skills through farmer field schools (FFS), self-help groups (SHG), various farmer social networks and media. All these scaling efforts are coherent, inclusive and effective in different contexts and have played a crucial role in catalyzing the adoption and scaling up of CASI practices over the past nearly three years.
The merits of SCASI
The SCASI project has had a significant impact in Ethiopia, particularly in helping farmers improve productivity and soil health. As evidence of the project’s effectiveness in addressing the challenges farmers face, Birhan Abdulkadir noted that by adopting minimum tillage and using crop residues as mulch and compost, among other recommended practices, farmers have dramatically increased their maize yields. This approach not only improves productivity and soil health but also saves time on weeding and reduces production costs.
In August 2024, a delegation of donor representatives and implementing partners visited the Benishangul Gumuz Region and Wolaita Zone for a joint monitoring and evaluation field visit. This visit provided valuable insights into the impact of the project in Ethiopia. Interacting with technology adopters and government partners, the team observed positive results and encouraging examples of how the project is improving agricultural practices. These interactions highlighted the benefits of the interventions, reinforcing the project’s effectiveness in improving farmers’ livelihoods and promoting sustainable practices in the region. In total, 3,700 hectares of agricultural land in the Asosa zone are now using SCASI, demonstrating the project’s widespread impact.
Mr. Bobeker Holeta, Head of the Benishangul Regional State Bureau of Agriculture, emphasized the commitment to understanding the SCASI project over the past two years. He highlighted its effectiveness as a sustainable to improve farmers’ food security and climate resilience. As a result, the regional government has decided to expand the use of this technology to cover 50% of the region’s agricultural land. He believes this decision is an important step in supporting farmers and transforming the agricultural system, ultimately leading to a more resilient and productive agricultural landscape.
Mr. Beshir Hitman, a host farmer from Asosa Zone in Akendo Afafri village, has experienced significant benefits from adopting SCASI technology. Starting with just 0.4 hectares two years ago, he has now expanded his operations to 2.5 hectares. Previously, farmers relied on broadcasting and multiple tillage systems, which were effective but labour intensive. Mr Hitman points out that the SCASI methods have not only improved his crop production and productivity but have also saved him time and labor by minimizing weeding.

The thriving maize fields of farmer Fantan Karamala in Dunga Arumela village, Ura district, Asosa zone illustrate the effectiveness of the SCASI project. Her commitment has resulted in an impressive six quintals increase in maize yield. By incorporating mulching with crop diversification and expanding her demonstration to 2 hectares, she has successfully intercropped soybean with maize, significantly increasing her income.
Farmers in the Wolaita zone are also inspired by the principles and benefits of SCASI technology. Many have adopted sustainable practices that enhance productivity and improve soil health. The positive impact on yields and incomes has motivated these farmers to adopt innovative approaches, fostering a community-wide commitment to resilience and food security. Their shared experiences highlight the transformative potential of technology in their farming practices.

Adanech Bebiso shared her experience, stating, “We began using SCASI after the training we received in 2021. Along with inputs like improved seeds, ginger, taro, sweet potatoes, and forage plants, we also received regular technical support. Previously, using conventional techniques yielded minimal results for many years. SCASI has transformed our operations, and we are reaping the benefits. I started with a 60x40m plot, and my maize harvest increased dramatically from 6 to 16 quintals. This farm has improved our lives in many ways, and we are truly benefiting from this endeavor.”
The reduction of multiple tillage and the production of organic fertilizers, such as vermicompost, have empowered women to become more actively involved in farming. In addition, the availability of fodder has opened up new opportunities for farmers, allowing them to explore alternative businesses such as livestock fattening and dairy production. Many farmers are replacing local cows with improved varieties to enhance milk production and dairy quality.
These changes not only improve the farmers’ livelihoods but also foster social cohesion and build economic capital within the community. For example, the establishment of Self-Help Groups (SHGs) has become a valuable platform for technology transfer, financial savings, and access to credit, further supporting their agricultural and business endeavors.
Host farmers like Amarech Koricho play a key role in their communities by sharing their knowledge. She has trained around 50 fellow farmers in her area about SCASI practices. As a result, these farmers are thriving and actively adopting CASI practices to improve their land management and crop production. Their collective efforts are having a significant impact on sustainable agriculture in the region.
During the joint monitoring visit facilitated by CIMMYT, Tilahun Tadesse, Program Manager of the Terepeza Development Association (TDA), emphasized the advantages of the SCASI approach. He noted that farmers wereexperiencing higher yields per hectare and greater resilience during droughts compared to conventional methods. He attributed the success of these trials to farmers’ commitment, progressive learning, and increased awareness. The variety ofcrops grown onthe demonstration plots are producingimpressive results, further demonstratingthe effectiveness of the SCASI project.
Lessons and future directions
Action research conducted over two years in four regions of Ethiopia highlights the potential of SCASI to drive agricultural transformation. By integrating conservation agriculture with sustainable intensification principles, it effectively addresses immediate agricultural challenges while building resilience to the impacts of climate change. This initiative goes beyond increasing agricultural productivity and improving soil health; it also promotes the expansion of social capital and strengthens system resilience. The practices have effectively reached rural communities through various channels, including radio, demonstrating that targeted, long-term promotion efforts increase the uptake of CASI. The tangible successes experienced of early adopters motivate non-adopters to join the movement. Additionally, host farmers play a crucial role in cascading knowledge and practices to their peers, further facilitating the scaling up of CASI practices. By combining sustainable farming practices with community-based solutions, SCASI empowers farmers to overcome collectively address challenges.
Looking ahead, a sustained commitment to institutional capacity building, the integration of CASI-friendly policies into regional and national frameworks, and effective resource mobilization will be critical to sustaining the momentum of SCASI and expanding its benefits throughout Ethiopia. By expanding the initiative’s reach, CIMMYT and its partners aim to foster a more resilient, productive and sustainable agricultural future that adapts to the country’s diverse agro-ecological conditions. This collective effort will not only improve food security but also empower communities to thrive in the face of climate challenges.
CIMMYT collaborated with Tecnologico de Monterrey’s FEMSA Biotechnology Center in the development and validation of nutraceutical corn. By leveraging Mexico’s maize diversity through the world’s largest germplasm bank, CIMMYT contributed expertise in crossbreeding to help incorporate traits such as higher protein, fatty acids, and antioxidants, supporting advancements in food security and sustainable agriculture.
Senior representatives from CIMMYT visited the John Innes Centre to strengthen their strategic partnership focused on advancing global wheat research. Key collaborative efforts include the Wheat Disease Early Warning Advisory System (DEWAS) and research on genetic resistance to wheat blast. CIMMYT’s Director General, Dr. Bram Govaerts, emphasized the long-standing partnership’s global impact, noting that around 70% of the world’s wheat is linked to CIMMYT’s network. Dr. Sarah Hearne, Chief Science and Innovation Officer, highlighted the shared commitment to providing sustainable solutions that enhance farmers’ resilience and productivity worldwide.
From 11 -22 November 2024, global leaders convened in Baku, Azerbaijan for COP29. Dubbed the finance COP, critical intersections of climate change, food systems, and sustainable development took center stage. This year’s conference reflected both the progress and the persistent challenges in addressing the climate crisis, marking a critical moment in the climate negotiations.
Food Systems at the Forefront
COP29 highlighted the undeniable importance of transforming global food systems as a cornerstone of effective climate action. Initiatives like the Harmoniya platform and the Declaration on Methane from Organic Waste shows the global community’s recognition of agriculture as both a contributor to and a solution for greenhouse gas emissions. However, the broader discussions were a reminder of the gap between ambition and implementation, with financial commitments and concrete action plans often falling short.
While food systems gained visibility, the debates often revealed tensions, particularly on issues like global stocktake outcomes, financing, and the integration of mitigation and adaptation strategies. Despite these challenges, the coordination and cohesion within the food systems community were commendable, reflecting a collective resolve to carry the momentum forward.
COP 29 – Baku, Azerbaijan
Key Outcomes and Agreements
Climate Finance and the NCQG
A central focus of COP29 was the New Collective Quantified Goal on climate finance (NCQG). While the actual need for climate finance is estimated at $1.3 trillion annually, the outcomes of COP29 fell short, with only $300 billion explicitly committed to developing countries. The inclusion of voluntary contributions from non-traditional donors like China and the UAE added nuance but failed to resolve the broader financial gaps.
Mitigation Work Programme
Discussions on the Mitigation Work Programme highlighted fundamental disagreements over whether the program should prioritize specific actions linked to the global stocktake. While some nations sought prescriptive approaches, others emphasized the voluntary nature of nationally determined contributions (NDCs). These debates highlight the complexities of aligning global and national climate priorities.
Adaptation and Resilience
The global goal on adaptation progressed with the launch of the Baku Adaptation Roadmap, though challenges remain in refining and agreeing upon adaptation-related indicators. Meanwhile, the Sharm El Sheikh Joint Work on Agriculture and Food Security moved forward with plans for an online portal to share best practices and tools for climate action.
Collaborative Frameworks
The conference saw advancements in collaborative mechanisms such as the Paris Agreement Crediting Mechanism under Article 6, which aims to enhance transparency and accountability in carbon markets. Platforms like Harmoniya and the Global Nitrous Oxide Hub were also launched to streamline efforts in addressing specific climate challenges.

At the Mechanization and Extension activity’s exhibition stand, visitors explored an array of machinery specifically tailored to small-scale farming needs. Among the featured equipment were basin diggers, two-wheel tractors, multi-crop threshers, chopper grinders, trailers, and peanut butter processing machines, including a groundnut sheller, peanut roaster, and peanut butter-making machine. Each piece of equipment aligns with existing activities within the initiative to demonstrate practical solutions for improving labor efficiency and enhancing crop productivity which might be needed during agroecology transitions.
The basin digger drew significant attention, especially from farmers encountering it for the first time or wanting to know more about how they could become service providers. Designed for creating basins such as those established under the Pfumvudza/Intwasa conservation agriculture program, the basin digger can significantly reduce labor and time in land preparation, especially for those with limited access to manual labor.
The service provision model: a pathway to accessible mechanization
Participants interested in the service provision model received first-hand information on the benefits of the program and how they could sign up. The service provision model is a key part of the Feed the Future Zimbabwe Mechanization and Extension activity, designed to facilitate year-round access to mechanization services in farming communities.
Through this model, trained service providers are established locally, offering a range of fee-based services, including land preparation, crop management, post-harvest processing, value addition, and transportation. This model makes essential machinery accessible to farmers without requiring them to purchase it outright. To support the establishment of service providers, three financing options are offered:
Loan facility: Prospective service providers apply for a loan from BancABC, with a 30% initial deposit of the total machinery cost. Upon approval, the balance is paid directly to the machinery supplier, who then delivers the equipment.
Hire purchase agreement: Service providers may opt for a hire purchase arrangement with the manufacturer, where machinery is provided after an agreed deposit, with the remaining balance paid over three to four months.
Outright cash purchase: Community members with funds can purchase machinery.
Strong community interest and prospects for growth
The Mechanization and Extension activity stand generated substantial interest among farmers in both districts. In Murewa, 95 participants engaged with the display, with eight potential service providers expressing interest in acquiring the peanut butter-making machine, manual groundnut sheller, and peanut roaster. Groundnut production is high in Murewa, so farmers were especially intrigued by the value addition machinery, which opens new opportunities for processing and marketing.
“As groundnut farmers, these machines will give us a business opportunity to sell peanut butter in large quantities,” said attendee Colleta Nzara of Murewa district.
“We used to lose so much money by just selling unshelled groundnuts because very few could manually process into peanut butter, but with these machines, the whole process is so much easier,” said Florence Mutize of Murewa district.
In Mbire, where 57 participants visited the stand, the basin digger was a major attraction.
“This is the first time I am seeing this machine that can ease our labor burdens when making our Pfumvudza plots,” said Jennifer Nyatande from Mbire district. “I’m eager to invest in one to both reduce costs on my farm and offer services to others.“

The 2024 Agroecology Fairs provided an opportunity to demonstrate how mechanization can be both accessible and transformative for smallholder farmers. With growing interest from local communities, the Mechanization and Extension activity continues to work toward sustainable agricultural development across Zimbabwe’s rural districts.
Sundhani Tharu, a 44-year-old farmer from Pattharbojhi, Madhuwan-1 in the Bardiya district, in the mid-west of Kathmandu, is a leading example of how sustainable agricultural practices not only enhance crop production but also contribute to human and environmental health. Her dedication to a balanced approach to farming, which includes crop-livestock integration and the principles of the 4Rs of nutrient stewardship, has had a significant impact on her farm and the wider community.
Sundhani lives in a joint family of 58 members, with farming as the primary source of income. On their 8.13 hectares of land, they grow staple crops like rice, maize, mustard, and lentils, while also raising 26 cows, 17 buffaloes, and 45 sheep. Through this integration of crop production and livestock, Sundhani has built a closed-loop farming system where farmyard manure (FYM) from the livestock nourishes the crops, and crop residues feed the animals, ensuring minimal waste and promoting a natural balance between animals, crops, and soil health.

Central to her success is her application of the 4Rs of nutrient stewardship, which involves applying the right source of nutrients at the right rate, at the right time, and in the right place. This approach ensures that her crops receive the essential nutrients they need while minimizing environmental impact. With support from the USAID-supported Nepal Seed and Fertilizer (NSAF) Project, implemented by CIMMYT, Sundhani has been trained in nutrient management techniques, including the 4R principles. These practices have helped her optimize fertilizer use and significantly improve her crop yields, doubling her maize production from 30 to 60 quintals per hectare.
Sundhani also prioritizes the use of farmyard manure, which plays a vital role in her farming system. The manure from her livestock is carefully composted and used as a natural fertilizer, enriching the soil with organic matter and nutrients. This reduces her reliance on synthetic fertilizers, which can harm the environment and deplete soil health over time. By using farmyard manure, Sundhani is not only improving soil fertility but also promoting a healthier ecosystem for future generations.
Similarly, the importance of a healthy diet is another key focus of Sundhani’s farming journey. Her farm provides her family with a diverse range of crops, including rice, maize, mustard, and vegetables like cauliflower, tomatoes, and potatoes. These crops contribute to a balanced, nutrient-rich diet for her large family, ensuring that they receive essential nutrients from fresh, organic produce. Sundhani’s vegetable farming is further enhanced through climate-smart practices like intercropping and mulching, which protect the soil, conserve water, and increase the variety of crops she can grow.
In addition to her focus on nutrient management and healthy diets, Sundhani has embraced Integrated Soil Fertility Management (ISFM), a holistic approach to soil health. ISFM combines organic and inorganic fertilizers, along with improved crop varieties and efficient nutrient management techniques, to enhance soil fertility and ensure long-term agricultural productivity. Through ISFM, Sundhani has achieved sustainable growth in her farming operations while safeguarding the environment for future generations.

Though Sundhani can hardly read or write, she is contributing to the “One Health” movement—a global initiative that connects the health of people, animals, and the environment through best management practices in agriculture. By integrating crops and livestock, using farmyard manure, and applying the 4Rs of nutrient stewardship, she promotes a sustainable, eco-friendly system that enhances food security, improves soil health, and protects natural resources.
Looking ahead, Sundhani is determined to expand her farming ventures. She plans to venture into seed production for rice and mustard and hopes to increase her earnings from NPR 5 lakh (USD 3,740) to NPR 8 lakh (USD 5,987). By continuing to inspire her community and advocate for local vegetable markets, Sundhani envisions a future where farming is not only a source of livelihood but a cornerstone for a healthy, thriving ecosystem.
Sundhani Tharu’s story highlights the power of nutrient stewardship and sustainable farming to create healthier soils, crops, and communities. Through her dedication to the 4Rs, ISFM, and promoting farmyard manure use, she is paving the way for a future where agriculture is in harmony with nature—benefiting both people and the planet.
CIMMYT’s economists Adeeth Cariappa and Vijesh Krishna examine the potential of agricultural carbon markets to boost sustainable farming in India while addressing climate change. Their study, published in Climate Policy, reviewed seven carbon farming projects in Haryana and Madhya Pradesh, finding limited participation from smallholders and marginalized communities, with women making up just 4% of participants.
Although new sustainable practices such as zero tillage and intercropping were adopted, key challenges remain, including poor communication, insufficient training, and delayed payments—resulting in nearly 28% of farmers abandoning these practices. To improve outcomes, the authors recommend offering better financial incentives, ensuring timely payments, and improving project implementation through partnerships with research institutions. Digital technologies like remote sensing and satellite imagery are expected to play a critical role in improving carbon credit monitoring and farmer participation going forward.
CIMMYT is happy to announce four new, improved tropical and subtropical maize hybrids that are now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Latin America and similar agro-ecologies in other regions. NARES and seed companies are hereby invited to apply for licenses to pursue national release, scale-up seed production, and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is January 31st, 2025. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrids were identified through rigorous, years-long trialing and a stage-gate advancement process which culminated in the LT23-STG5-THW, LT23-STG5-THY, and 01-23MASTCHSTW Stage 5 Trials. The products were found to meet the stringent performance and farmer acceptance criteria for CIMMYT’s breeding pipelines that are designed to generate products tailored in particular for smallholder farmers in stress-prone agroecologies of Latin America.
CIMMYT, through the CGIAR-supported Ukama Ustawi initiative, is supporting women farmers in Zimbabwe to lead the fight against climate change. By adopting climate-smart practices like zero tillage and growing drought-resistant crops such as orange maize, cowpeas, and lab-lab, farmers like Susan Chinyengetere are ensuring food security, generating income, and inspiring others. These techniques not only strengthen resilience against erratic weather but also enable women to balance traditional roles while driving sustainable agriculture. With access to affordable seeds, mechanization, and strong farmer networks, CIMMYT is fostering lasting solutions to climate adaptation across Zimbabwe and beyond.
