Soil health is fundamental to agricultural productivity, food security, and climate resilience. In Ethiopia and Nepal, deteriorating soil conditions—driven by acidity, nutrient depletion, and land degradation—pose a significant challenge to farmers and policymakers alike. Addressing these issues is not just a technical necessity but a pathway to ensuring long-term agricultural sustainability and economic stability.

Recognizing these shared challenges, CIMMYT facilitated a South-South exchange between Ethiopia and Nepal to foster collaboration, exchange knowledge, and explore innovative solutions for improving soil health.

Shared challenges, shared solutions

Both Ethiopia and Nepal face persistent soil health challenges that hinder agricultural productivity. In Ethiopia, soil degradation—stemming from issues like soil acidity, salinity, and nutrient depletion—has become a barrier to achieving higher agricultural productivity. Similarly, Nepal is navigating soil health concerns amidst small landholdings, urban migration, and climate impacts.

For both nations, sustainable soil management is critical to strengthening their agricultural sectors. This exchange provided an opportunity for researchers, policymakers, and agricultural experts to learn from each other’s experiences, leveraging successful approaches to improve soil quality and boost productivity.

A unique exchange of knowledge

From November 25–28, a Nepalese delegation—including CIMMYT scientists and representatives from Nepal’s Ministry of Agriculture and Livestock Development (MoALD) and the Nepal Agricultural Research Council (NARC)—visited Ethiopia to gain insights into its soil health initiatives.

Ethiopia has made significant progress in soil management through collaborations between government agencies, research institutions, and international partners. With CIMMYT’s support, the country has developed a National Soil Information System (NSIS), a comprehensive data-driven approach that guides interventions to improve soil health, increase productivity, and enhance food security.

During the visit, the Nepalese delegation met with leading Ethiopian institutions, including:

  • The Ministry of Agriculture (MoA)
  • The Ethiopian Institute of Agricultural Research (EIAR)
  • The Agricultural Transformation Institute (ATI)
  • The Holeta Agricultural Research Center
  • The National Agricultural Biotechnology Research Center

Through site visits and discussions, the delegation explored Ethiopia’s Vertisol management strategies, sub-soil acidity solutions, and data-driven soil health policies—areas that could be adapted to Nepal’s agricultural landscape.

A shared commitment to agricultural innovation

Beyond knowledge exchange, the visit served as a catalyst for long-term collaboration between the two countries. CIMMYT has been working in Ethiopia for over three decades, supporting research and technology development to enhance soil health and food security. In Nepal, CIMMYT scientists collaborate with national partners to strengthen agricultural commercialization and climate resilience.

During their visit, Nepalese delegates expressed particular interest in Ethiopia’s Geo-Nutrition approach, which connects soil quality to human health by analyzing how soil nutrients influence the nutritional value of crops. Nepal sees great potential in adopting this model to enhance both agricultural and public health outcomes.

Shanta Karki, Joint Secretary at Nepal’s Ministry of Agriculture and Livestock Development, reflected on the visit: “The insights we gained in Ethiopia will be instrumental in improving our soil health strategies.

We see great potential for collaboration between Ethiopia and Nepal in tackling common challenges like soil acidity and water management.” She added that another key area of learning was Geo-Nutrition, an innovative field that connects soil health to human health.

The concept, which Ethiopia has been actively exploring, looks at how soil quality influences the nutritional value of crops and ultimately the health of the populations that depend on them. The Nepalese delegation saw this as an opportunity to further develop their own approach to improving soil and human health simultaneously.

Looking Ahead: Building stronger partnerships

As CIMMYT continues to facilitate South-South exchanges, the goal is to adapt successful models from Ethiopia to Nepal while drawing lessons from Nepal’s unique agricultural landscape. The delegation left Ethiopia with renewed motivation to enhance soil health, not just for the benefit of farmers but for broader food security and economic resilience.

Narayan Prasad Khanal, Business Development Manager at CIMMYT Nepal, emphasized the importance of such exchanges. “The lessons learned here, particularly on sub-soil acidity management and Geo-Nutrition, will be crucial for enhancing our regulatory systems and addressing challenges in Nepal’s agriculture. This experience has shown us how important it is to adapt successful models from other countries and incorporate them into our own agricultural practices.

Shree Prasad Vista, Senior Scientist at the Nepal Agricultural Research Council (NARC), was particularly fascinated by Ethiopia’s innovative work on Vertisol management and soil acidity. He remarked, “The insights we gained from CIMMYT, particularly on Geo-Nutrition and soil acidity, will help enhance our agricultural practices and regulatory systems in Nepal.”

A Path toward collaborative solutions

As Ethiopia and Nepal continue to navigate similar agricultural challenges, the knowledge gained from this exchange will play a crucial role in shaping future soil health strategies. By learning from each other’s successes, both countries are positioning themselves to implement sustainable, climate-resilient soil management practices tailored to their unique context.

This exchange stands as a powerful example of how international collaboration fosters innovation, resilience, and food security. Through shared expertise and collective action, Ethiopia and Nepal are laying the foundation for stronger agricultural systems that will benefit future generations.

An entrepreneur’s journey in aquaculture: Fueled by partnership, innovation, and resilience

Written by dmedina on . Posted in Blogs.

Cosmas Chachi, a 46-year-old businessman, owns Triple Blessing Supermarket in Zambia’s Luwingu District. In 2000, Cosmas identified an opportunity to address the growing demand for fresh fish in his community and started selling the product in his local area. Like many rural entrepreneurs, Cosmas faced initial challenges such as unreliable supply chains, insufficient cold storage, and limited access to financing, all of which prevented him from meeting the rising demand from local customers. Undeterred, Cosmas embarked on a transformative journey into aquaculture.  

The turning point for Cosmas occurred in April 2023 when he participated in a training program on integrated aquaculture under the aegis of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, led by CIMMYT. The training implemented by the International Water Management Institute (IWMI), one of the key implementing partners of the project, emphasized sustainable intensification and equipped Cosmas with advanced skills in sustainable feed management, water quality control, efficient harvesting methods, and business management, among other areas.

“The training equipped me with expert knowledge in aquaculture management and skills to design and operate efficient fishponds,” Cosmas said. 

With his new-found expertise, Cosmas upgraded three of his existing fishponds and built six more, each measuring 13×15 meters. To meet customer demand, he introduced a strategic stocking system, staggering the placement of 1,000 fingerlings across his nine ponds. This innovation ensured consistent fish supply even during Zambia’s annual fish ban. “By stocking and harvesting my ponds, I can maintain a steady supply even during the national fish ban when local supply decreases because some other farmers who supply my supermarket depend on fish from natural water bodies,” Cosmas shared.  

Creating livelihoods and building resilience

Cosmas’ aquaculture enterprise has become an economic engine in his community, employing 25 permanent workers, primarily local youth, and offering seasonal jobs to 12 more. For Emmanuel Makumba, a shop attendant at Triple Blessing supermarket for the last eight years, the opportunity has been life changing. “The job at the supermarket helped me relocate from my village, build my own house, and send my children to a private school,” said Emmanuel. 

In June 2024, his business received a significant boost with the installation of a 15-ton cold storage facility, funded by IWMI through the AID-I project. The upgrade significantly reduced post-harvest losses and enhanced Cosmas’ fish storage capacity. It ensures a steady supply for his business and the farmers he supports, strengthening the local aquaculture value chain.  

“In the past, we could only purchase 50 to 100 kilograms (kg) of fish at a time, selling it at US$ 2.50 per kg,” Cosmas shared. With the new cold storage facility, Cosmas can now buy and store up to 700 kg of fish per harvest without the risk of spoilage. The effort not only secures a reliable supply for his business but also creates a dependable market for local consumers, fostering growth and sustainability in the region’s aquaculture sector.  

A ripple effect of progress: Expanding aquaculture for community impact

Today, Cosmas’ success goes beyond his supermarket. He owns a thriving restaurant, offering customers a unique dining experience with fresh fish from his ponds. “The training I received during the AID-I workshops helped me transform my passion for aquaculture into a successful business. Now, in addition to the supermarket, I own a popular restaurant and outdoor fishponds, offering customers a unique dining experience,” he said.

Building on his business success, Cosmas has further expanded his impact by transforming his fishponds into practical classrooms, offering free, hands-on training to aspiring fish farmers. Over the past year, he has trained 50 farmers in sustainable aquaculture best practices.  

As more farmers in Luwingu adopt these practices, local food security improves, and income streams diversify. Cosmas’ leadership is stabilizing the community’s food supply and improving diets with nutrient-rich fish. This aligns with AID-I’s broader goal to promote sustainable and scalable agricultural models.  

By September 2024, the AID-I project, through IWMI’s efforts, had supported 297 fish farmers with training, market linkages, and tools for success across Northern and Luapula Provinces: creating a ripple effect of progress and also addressing Zambia’s fish supply and demand gap. The project empowers communities to adopt innovative and sustainable aquaculture practices, driving growth in fish production and ensuring a more reliable supply to meet the needs of a growing population. As fish is a critical source of protein and essential nutrients, fostering a sustainable aquaculture sector is vital for supporting Zambia’s food security and nutritional goals.  

Cosmas’ journey exemplifies the power of partnerships, innovation, and resilience in driving community progress. It underscores the potential for a robust aquaculture sector in Zambia, where challenges spur solutions and success benefit entire communities. Through AID-I’s comprehensive interventions, Cosmas’ story of transformation offers a vision for sustainable development in rural Zambia, led by innovation and community empowerment.

The land that gives life: Tomasa and Fabián’s plot

Written by dmedina on . Posted in Blogs.

Somewhere in the enchanted valley of Santa Catarina Lachatao, Oaxaca, under the vast blue sky and in the heart of a land full of history and hope, Fabián Marcos Cano and Tomasa García Pérez are working toward the future they have long envisioned, their hands deep in the soil. In this land, where the Zapotec language gives its name to the territory, each seed sown by their hands is an act of trust.

Fabián, his gaze marked by years of experience, speaks of his land with the pride of someone who has learned to listen to the voice of the earth. “We used to plant the way God guided us,” he says, recalling the days when farming was a practice of intuition and inherited wisdom.

Today, with the support of SEFADER technicians like Reinalda Gómez and her team, they have transformed their approach to farming. Fabián and Tomasa have learned to respect the rhythms of the soil, to give back what they take, and to see each plant through a new lens. “It’s like food for food,” Fabián explains.

Corn and beans grow unhurriedly in their fields. The land is enriched with crop residues that were once fed only to livestock, along with compost that was once discarded. “It’s a lot of work, but it’s our life,” says Fabián, with the firm determination of someone who understands that effort is part of the cycle.

For Tomasa, each harvest is a link to her ancestors. “The land gives us life,” she says with unwavering certainty. In her fields, milpa thrives alongside squash, beans, amaranth, and purslane, in a balance that requires patience and respect. She has learned to let nature do its work, to understand that burning fields robs the soil of its ability to renew itself. “We pile up the weeds, let them decompose, and that’s how the land nourishes itself,” she explains.

The journey has not been easy. Last year, a violent storm destroyed much of their crop. “It grew beautifully, but the wind tore everything down,” Fabián recalls with resignation. But they are not giving up. “We make do with what God gives us, because it is more than enough for us.” What remains is harvested as seed for the next cycle.

Every application of bio-inputs, every crop diversification, every lesson shared by agricultural engineers has changed their way of farming and their understanding of life. The land, once seen as an adversary that imposed its own rules, is now an ally that responds generously to care.

The story of Fabián and Tomasa is a testament to resilience and learning. It is proof that agriculture can be different, that tradition and innovation can go hand in hand. Because in every bean they harvest, in every ear of corn they save for the next cycle, there is a valuable lesson: the land gives back what it receives. And in Santa Catarina, under the sun that shines on Fabián and Tomasa’s fields, life flourishes with strength.

Advancing gender and social inclusion in agroecology: Insights from the CGIAR Agroecology Initiative in Zimbabwe

Written by mcallejas on . Posted in Blogs.

Agriculture lies at the core of rural livelihoods, yet longstanding social inequities have stifled the potential of marginalized groups– particularly women and youth– to fully benefit. The CGIAR Agroecology Initiative (AE-I) recognizes gender and social inclusion as critical pillars in achieving sustainable agricultural transformation. By embedding these aspects within its framework, AE-I ensures that marginalized groups—especially women and youth—play a meaningful role in agroecology transitions.  

Current realities on women and youth in agriculture

Women and youth are central to Zimbabwe’s agricultural economy, yet they remain underrepresented or excluded in decision-making processes and face barriers to accessing   critical resources. Globally, women make up about 48% of the agricultural labor force in Sub-Saharan Africa (World Bank, 2024), yet they consistently face challenges in accessing land, credit, and markets. In Zimbabwe, these disparities are even more pronounced. In  Mbire and Murehwa districts, rural economic activities, including agriculture, rely heavily on women and youth. Women make up approximately 70% of the agricultural labor force (UNDP, 2024) in these regions, but they often lack control over resources needed to enhance productivity and economic stability such as land, credit, and markets.  

Agroecology Living Landscapes and Gender and Social Inclusion Matter

Embedding gender and social inclusion (GESI) into agroecology is not just a moral imperative but a foundational requirement for achieving lasting and transformative impact. Traditional top-down development approaches have often neglected marginalized groups’ unique needs and contributions, resulting in unsustainable outcomes. In contrast, the AE-I prioritizes inclusive and participatory processes, exemplified by its Agroecology Living Landscapes (ALLs), which serve as collaborative spaces where community members actively co-create locally relevant solutions.   

Central to the CGIAR Agroecology Initiative (AE-I) is a commitment to “do no harm—say no harm,” ensuring that the inclusion of women, youth, and other marginalized groups is safe, meaningful, and impactful. Including marginalized groups can disrupt existing power structures and opportunity hierarchies, so it must be done with contextual sensitivity. Young and old women are provided equal opportunities to participate in and contribute to the co-creation of innovations. However, systemic barriers-such as limited agency or entrenched gender norms-continue to hinder meaningful engagement. To address these challenges, AE-I collaborates with key stakeholders, such as the Ministry of Women Affairs, Community, Small and Medium Enterprises Development (MWACSMED), to advocate for gender mainstreaming. Concrete actions have included training programs, documentation of gender norms and their impacts, elevating women and youth role models, and ensuring equal participation in ALL activities. MWACSMED has evolved into a proactive stakeholder in this process. Initially a passive participant in ALL discussions, the ministry now plays a leadership role in addressing gender and social inclusion issues within the landscapes. This deliberate attention to GESI within ALLs has illuminated systemic barriers such as unequal access to resources, rigid cultural norms, and the exclusion of certain social groups.

Agroecology recognizes that inclusion is not merely about representation but about fostering environments where meaningful transformation can happen. For instance, cultural norms often limit the participation of women and youth in mixed-group activities. To address this, the AE-I initiated monthly “dialogues with elders,” engaging traditional authorities and community leaders to reconcile cultural traditions with transformative gender and social inclusion goals. These dialogues have yielded positive shifts in such perspectives. As one elder participant noted, “We value inputs from women and acknowledge their critical role in our community.”   

The transformative impacts of AE-I’s inclusive approach are increasingly visible. Across Murehwa and Mbire districts, Agroecology Living Landscapes (ALLs) are reshaping community dynamics by empowering previously marginalized groups, such as elderly women, to contribute to agricultural innovation. Within some of the activities of the Initiative, women and youth engagement is quite impressive, with over 60% of participants in seed fairs and field days. These figures highlight the significant potential for expanding women’s and youth’s opportunities to advance agroecological goals through gender- and youth-focused interventions. It also demonstrates their eagerness to engage in knowledge-sharing opportunities. Such initiatives improve livelihoods and build women’s and youths’ agency as active contributors to agricultural innovations. 

Inclusivity within ALLs is further is reinforced by low barriers to entry, emphasizing a willingness to learn and transform their crop and livestock production rather than asset ownership. This approach has expanded participation among resource-poor farmers, breaking down traditional exclusionary practices brought by other Donor programs.  

As one farmer remarked, “In the past, only those with cattle or fenced homesteads could join such programs on transformative change. Now, even those of us without such assets can participate.”  

Such practices have strengthened the confidence of marginalized farmers, enabling them to navigate complex production dynamics collectively.   

Building Economic Independence and Transforming Food Systems

The AE-I’s focus on inclusive value chains has begun to yield tangible economic benefits. In Mbire and Murehwa, women are transitioning from subsistence farming to economic independence by engaging in agroecological business models. For example, Sasso poultry farming has become a viable income-generating activity, allowing women to reinvest in their farm-level activities. Youth are also leveraging their involvement in agriculture to build assets, diversify income and nutritional sources, and secure a more stable future. 

A critical challenge remains exploitative market dynamics that limit farmers profitability. Farmers have raised concerns about the informal urban markets, where asymmetric power dynamics and a lack of competitive pricing mechanisms enable buyers to dictate unfavorable prices. Middlemen in the poultry markets suppress prices by 40%, while unstructured sorghum buyers pay 20–30% below market rates, eroding farmers’ profitability.  

Addressing these bottlenecks through cooperative-led marketing, digital trading platforms (e.g., Hamara App), and guaranteed off-take agreements ensures equitable economic participation and a resilient food system. 

Drudgery and Women in Agri-Food Systems

The transition to agroecology offers both opportunities and challenges, particularly for women, who bear the brunt of agricultural labor. In many rural communities, women are responsible for labor-intensive activities, including land preparation, weeding, and post-harvest handling.  

While agroecological practices promote sustainability and resilience, some approaches—such as conservation agriculture—can initially increase women’s workload, exacerbating drudgery and limiting their time for other economic or social activities.  

To ensure that agroecology transitions are both equitable and scalable, it is essential to integrate appropriate-scale mechanization that reduces labor burdens while maintaining ecological integrity. By embedding gender-responsive technologies into agroecological systems, AE-I can foster inclusive, productive and sustainable farming solutions.

To address this, the Initiative has facilitated the adoption of labor-saving technologies, improving access to mechanized solutions that ease women’s workload. In Mbire and Murehwa districts, 43 out of 95 women farmers now have access to basin diggers, significantly reducing the effort required to establish planting basins in conservation agriculture. Additionally, four multigrain threshers have been introduced in each district, enabling women to process small grain cereals more efficiently, cutting down the time spent on post-harvest handling.  

These innovations not only alleviate physical strain but also increase productivity, allowing women to participate in value-added activities and play a greater role in decision-making processes within the food system.  

By prioritizing appropriate-scale mechanization, the AE-I ensures that agroecology transitions foster inclusivity, sustainability, and economic empowerment for women farmers. 

Wrap up

The CGIAR Agroecology Initiative’s work in Mbire and Murehwa provides a step forward for centering gender and social inclusion into agricultural development. Through participatory methods, inclusive partnerships, and a focus on actor agency and opportunity for behavior change, the Initiative has redefined what it means to build sustainable and equitable food systems. For donors, partners, and other stakeholders, the AE-I offers a compelling case for investing in inclusive approaches that transform agriculture and uplift entire communities. As agroecology continues to evolve, centering gender and social inclusion will remain vital for achieving sustainable, impactful outcomes.  

 

Time Running Out to Avert Food Catastrophe, but There Is Hope

Written by dmedina on . Posted in Director General's corner, Features.

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.

Advisory services boost bean farming in Malawi

Written by dmedina on . Posted in Blogs.

For Malawian farmers Monica Levison and Liden Mbengo, the 2023-24 cropping season posed distinct challenges compared to prior years. Like many of their fellow smallholders, they grappled with the El Niño-induced drought, which severely impacted agricultural production across Southern Africa.

Despite these challenges, smallholders demonstrated extraordinary resilience due to crucial advisory services provided by the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub Project. The initiative enabled farmers to adopt climate-smart practices such as using drought-tolerant seeds and improved soil management techniques.

Connecting Farmers to Innovative Tools and Information

At the core of AID-I’s approach lies the delivery of innovative advisory services and proven agricultural technologies—strategies that have transformed the lives of farmers like Monica and Liden.

The AID-I project is transforming agriculture in targeted regions of the Democratic Republic of Congo, Malawi, Tanzania, and Zambia.

By providing smallholder farmers with critical information and innovative solutions, AID-I empowers them to enhance food production. The project focuses on strengthening legume and maize seed systems to enhance the availability and access to multi-stress-tolerant and nutritious crops. It also emphasizes delivering agricultural advisories to the last mile and improving soil health and fertilizer efficiency. These efforts are compounded with extensive training conducted by the Alliance of Bioversity International and CIAT through the Pan-Africa Bean Research Alliance (PABRA).

Seed Multiplication: A Key Entry Point for AID-I in Malawi

In Malawi, seed multiplication is a critical entry point for AID-I interventions. This approach ensures that farmers have access to high-quality, locally adapted seeds, reinforcing seed systems while supporting food security and resilience among smallholders. Through a network of demonstration plots, the initiative introduced high-demand bean varieties while showcasing modern agronomic practices, including proper planting techniques, precise fertilizer application, and effective pest and disease control strategies. These hands-on demonstrations equipped Malawian farmers with practical and sustainable methods to optimize bean cultivation, even during challenging conditions.

Monica’s Journey: From Small Harvests to Realizing Her Dreams

In Thambolagwa village, Monica had spent more than two decades growing beans only for her family’s consumption. After attending AID-I’s bean production training and receiving 2 kilograms (kg) of NUA35 seed from the demonstrations, she harvested 25 kg, significantly increasing her yield.

Building on this success, Monica planted the harvested seeds on one acre of land during the 2023-24 growing season and harvested 15 bags, each weighing 50 kg. She then sold part of her produce to Milele Agro Processing, earning over US$577.

“The training was incredibly valuable,” she said. “I’m looking forward to the 2024-25 season, during which I plan to expand my business by cultivating two acres of land. With the profits, I aim to make future investments in farming and save money to build a modern house for my family.”

AID-I Demonstrates the Power of Knowledge Through Mbengo’s Transformation

Liden, from Kang’oma Village, spent years planting four bean seeds in a single hole, unaware that this practice limited his agricultural potential. AID-I’s training introduced him to effective agronomic practices such as planting techniques, crop rotation, soil fertility improvement, and pest management as guided by PABRA.

“Following these guidelines, I harvested 15 kg of VTTT 924/4-4 and 18 kg of NUA35 from just half a kilogram of seed. In the previous year, I harvested only 3 kg after planting the same number of seeds and then nearly gave up on bean farming. The knowledge I have gained is priceless. It has reinforced my interest in bean farming and will stay with me forever,” said Mbengo.

Liden Mbengo, a farmer from Kang’oma Village, displays his impressive bean harvest, demonstrating the impact of AID-I training on improving yields and resilience.

A New Era for Malawian Bean Farmers

For extension workers such as Chrissy Minjale in Ntcheu district, the AID-I program has been transformative.

“The trainings were eye-opening for both us and the farmers,” she said. “Smallholder bean farmers in Malawi are likely to experience a significant increase in bean seed and grain production in the long run.”

Farmers and extension workers, inspect newly planted bean crops during a field visit, highlighting the hands-on learning provided by AID-I advisory services.

Field Learning and Adoption of Climate-Smart Practices

The program’s emphasis on linking farmers to off-takers, understanding climatic conditions, and adopting modern agronomic practices has sparked interest in bean farming across Malawi. As Yohane Nkhoma, a field extension officer in Ntchisi, observed:

“We now understand the importance of timing the first rains for beans and other crops. I’m committed to sharing this knowledge with hundreds of farmers in my area and helping them pay closer attention to the climatic conditions crucial for bean production. The results we have witnessed will encourage more farmers to engage in bean cultivation as a serious business.”

Scaling Impact: Training Thousands of Farmers

With over 11,007 farmers trained, 6,786 of whom are women, AID-I is not only improving yields but also empowering communities, building resilience, and igniting a wave of agricultural innovation.

The ripple effect of these interventions is clear. Beyond feeding their families, smallholder farmers are also paving the way for a more secure and sustainable future.

These individuals are more than beneficiaries. They are change agents whose successes inspire their communities and beyond.

As AID-I continues to amplify its impact, it is reshaping the trajectory of smallholder farming in Malawi and setting a precedent for resilience and food security across the region.

The future of farming here is thriving, innovative, and full of promise—as illustrated by Monica, Mbengo, and many more.

Exploring Azolla Farming as a Sustainable Feed Source for Poultry in Murehwa, Zimbabwe

Written by dmedina on . Posted in Blogs, News.

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.

Scaling Conservation Agriculture-based Sustainable Intensification in Ethiopia (SCASI): Empowering Farmers and Engaging Development Partners

Written by dmedina on . Posted in Features.

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 were experiencing 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 of crops grown on the demonstration plots are producing impressive results, further demonstrating the 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, the Borlaug Institute for South Asia (BISA), and the Indian Council of Agricultural Research (ICAR) jointly organized a three-week training course on conservation agriculture (CA) and regenerative agriculture (RA). The program focused on the potential of sustainable farming methods as vital tools for managing risks in agrifood systems in both irrigated and rainfed areas.

Held from December 3–23, 2024, the training brought together farmers, scientists, and stakeholders to explore innovative solutions to agrifood challenges. Sessions were held at the ICAR Indian Institute of Maize Research and BISA in Ludhiana, Punjab; the ICAR-Central Soil Salinity Research Institute in Karnal, Haryana; and the ICAR-Indian Institute of Farming Systems Research in Meerut, Uttar Pradesh, India.

Building Resilient Agrifood Systems

Conservation agriculture (CA) and regenerative agriculture (RA) are approaches to land management that prioritize ecosystem health. These practices are based on three core principles: minimal soil disturbance, continuous soil cover, and crop diversification. Together, they improve yields, restore natural resources, reduce farming costs, and develop resilient agricultural systems that protect the environment, enhance climate resilience, and improve rural livelihoods, particularly in the Global South.

In South Asia, where rural communities rely heavily on natural resources, farmers face significant challenges, including loss of soil fertility, water scarcity, pollution, and the effects of climate change. These pressures are straining agricultural systems, particularly in irrigated and dryland farming areas.

Despite the clear benefits of CA, adoption remains limited due to barriers such as lack of knowledge on how to implement CA in different agro-ecologies, limited access to appropriate tools, insufficient policy support, and low awareness of the long-term benefits of CA. To address these challenges, training and capacity development are essential for scaling up CA technologies among smallholder farmers and ensuring their long-term impact.

The Advanced Course on CA/RA in Asia was launched in 2010 by CIMMYT in partnership with the Indian Council of Agricultural Research (ICAR) to address the challenges of sustainable agriculture. Since its inception, advanced training workshops have been held annually, and this is the 13th edition.

The training bridges cutting-edge scientific research and multidisciplinary strategies, equipping participants with skills in sustainable intensification, diversification of production systems, resilience-building, and natural resource conservation. To date, CA training has benefited more than 220 researchers, policymakers, and development practitioners from 20 countries.

The 13th edition, held in India, welcomed mid-career researchers from Uzbekistan, Morocco, and India. The course was coordinated by Mahesh Gathala, Cropping Systems Agronomist, and Alison Laing, Agroecology Specialist, both from CIMMYT; Madhu Choudhary, Senior Scientist at ICAR-CSSRI; and Raj Kumar Jat, Senior Scientist at BISA.

Key Highlights of the Advanced Conservation Agriculture Training Course

The Advanced Conservation Agriculture (CA) course was inaugurated on December 4, 2024, at the NASC Complex in New Delhi. The inaugural address was delivered by S.K. Chaudhari, Deputy Director General for Natural Resource Management at ICAR, who highlighted the importance of CA in addressing climate challenges and managing agronomic risks. Chaudhari emphasized CIMMYT’s leadership in promoting CA in India and reflected on the impact of the program, saying, “I have been watching this course for many years. Many young scientists have benefited from this course.” He also fondly recalled the inaugural training session held 13 years ago and extended his best wishes to all the participants. Watch his complete statement here.

In Nepal, hope is slowly taking root in the mid-hills as communities and farmers transform traditional systems into productive, diversified, nutritious and market-oriented farming systems. Through the CGIAR Mixed Farming Systems (MFS) Initiative, farmers like Ms. Birma Sunar and communities like Gurbhakot in Surkhet are building a transformative pathway. Since 2022, CIMMYT and IWMI have been supporting communities in planning and engaging stakeholders in identifying organizational and technical solutions. The initiative aims to increase milk production through improved forages, improve nutrition and income diversification through high-value fruit trees, and improve water efficiency in vegetable production through micro-irrigation.   

Birma’s Journey: Overcoming Challenges, Cultivating Dreams

Birma Sunar, 49, a determined farmer from Surkhet, represents the aspirations of countless smallholder farmers struggling to survive on limited means. A Dalit woman and an amputee, her small plot of land was once dedicated to subsistence farming, leaving her family struggling to make ends meet. The maize and wheat she grew barely lasted a year, and her family of seven was struggling for food. With her husband earning meager wages as a day laborer, the family often faced food insecurity.  

Her perspective on farming began to change when she became involved with the Mixed Farming Initiative. Birma received training in the cultivation of high-value fruit trees and the planting of Napier grass to feed dairy cattle, as well as micro-irrigation techniques. With her new skills and the eight mango saplings and one lychee tree she received from the Initiative as part of  action research, she hopes to increase her family’s income..   

“I was unaware of commercial farming,” says Birma. “I have a lime tree and a banana tree in my field however, it used to be for home consumption. But now, once my mango and lychee trees start giving fruits, I hope to sell the produce in local markets and earn enough to buy essential household items and feed my family.”  

Last year, she planted high-value fruit saplings that are now growing into healthy plants, giving her hope for stability and food security in the future.

Youthful Aspirations: Santosh’s Agricultural Renaissance

After working abroad for a few years in the hope of a brighter future, Santosh KC, 25, returned home, disheartened yet determined. Equipped with the knowledge gained from his agricultural education and a passion for change, he started a nursery for high value fruit trees and improved forages and ventured into dairy farming with Napier grass.  

The journey was not easy. In the first year, Santosh faced losses, and his family doubted the viability of his efforts. But with unwavering dedication, he turned his fortunes around. Today, Santosh cultivates 45 ropanis (2.29 hectares) of land, raises 22 goats, and earns a steady income. He also participates in the Mixed Farming Initiative training organized jointly with the Gurbhakot municipality and mentors farmers on the benefits of mixed farming.   

“For many youths, farming doesn’t seem like a viable option. However, with support for modern agricultural techniques and market integration, we can build livelihoods that are not just sustainable but rewarding,” shares Santosh.  

A Municipal Vision: Building Resilient Communities

The Initiative has been jointly implemented by CIMMYT and IWMI in the local municipality of the working district. With the support of the initiative, the Gurbhakot municipality is playing a critical role in scaling up the benefits of mixed farming. Recognizing the value of the crops, the municipality has embraced Napier grass and high-value fruits as key components of its agricultural strategy. By prioritizing mangoes, lychees, oranges, and lemons, the municipality aims to improve household nutrition and create commercial opportunities for farmers.  

“We distributed high-value fruit trees to farmers last year under the theme ‘One Home, Two Fruit Plants’. This year, we’re planning a study to identify the best topography for different fruits. This knowledge will allow us to scale our goal to integrate these practices into larger public programs, creating decent livelihoods for farmers,” said Mr. Hasta Pun, Mayor of Gurbhakot Municipality.

A Vision for the Future  

The Mixed Farming Initiative has been critical in identifying solutions to bring tangible improvements to smallholder farmers like Birma and Santosh, but it has also strengthened local governance and resilience. In the three years of implementation, the pilot program in Gurbhakot in Surkhet and Halesi-Tuwachung in Khotang has set the stage for scaling up these efforts in more municipalities. By 2030, the initiative aims to impact 13 million people and ensure equitable opportunities for women, youth, and marginalized communities.  

By nurturing the saplings of high-value fruits and integrating forages, local leaders and farmers in the mid-hills of Nepal remain motivated and committed to rewriting their story —One of hope, resilience, and the promise of a food-secure future.   

Why early-stage on-farm sparse testing could be a game changer for crop breeding in Africa

Written by dmedina on . Posted in Blogs.

(Photo: CIMMYT)

Over 80% of the world’s 570 million farms are smallholder farms under 2 hectares, supporting rural livelihoods in impoverished regions. Smallholder farmers, who form a significant portion of the 690 million people experiencing hunger, need improved crop varieties to thrive under challenging conditions like low inputs, climate change stresses, and pests. 

Challenges of breeding for smallholder farmers 

Particularly at early stages, breeding programs face difficulties replicating the diverse and resource-constrained environments of smallholder farms, referred to as the Target Population of Environments (TPE). The TPE encompasses all locations where new crop varieties will be grown, characterized by varied biophysical conditions, environmental stresses, and farming practices. 

Conventional research stations, where new selection candidates are tested, don’t fully replicate smallholder conditions. Practices like manual labor for weed management or intercropping are common among smallholders but rarely modeled on research stations. This mismatch can lead to inaccurate predictions of crop performance on farms and discarding potentially successful candidate varieties. 

Early-Stage On-Farm Sparse Testing (OFST)

Early-stage OFST shifts testing to hundreds of smallholder farms at early stages, addressing two major issues. First, it evaluates crops under real-world, farmer-managed conditions. Second, it captures the diversity within the TPE by conducting trials on numerous farms. 

Using farm-as-incomplete-block (FAIB) designs, small farms test 3–5 candidate varieties, aligning with their plot size and resource constraints. A genomic relationship matrix connects trials across farms, ensuring comparability between farms and enhancing selection accuracy through the sharing of information. This approach reduce replication and enable testing more candidates, thereby improving breeding efficiency and providing a basis for accelerated parent recycling. Smallholder farmers are highly diverse, and careful sampling ensures a wide range of farmers can participate. The small land requirements of this approach allow small, poor and/or women farmers to equally participate.

On-Farm Testing and on-station testing: complementary yet demanding approaches

Early-stage on-farm testing complements, rather than replaces, on-station trials. Controlled assessments for traits like disease resistance and managed abiotic stresses remain essential at research stations. Conversely, insights from early-stage OFST can help refine on-station testing to better represent farming realities.

Scaling early-stage OFST demands strong partnerships between CGIAR, NARES, and farmers for decentralized trial management. Farmers must consent to participate and be compensated for risks. Additionally, significant resources and coordination are required to ensure trials are representative and reliable. 

Despite these challenges, early-stage OFST holds transformative potential. By aligning breeding programs with smallholder realities, it can deliver improved crop varieties faster and more effectively, enhancing food security for those who need it most.

The 29th Conference of the Parties (COP29): Navigating Food Systems and Climate Challenges

Written by dmedina on . Posted in News.

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 

  1. 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. 

  1. 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. 

  1. 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.

CIMMYT and the Indian Council of Agricultural Research (ICAR), New Delhi, co-hosted a one-day workshop on Long-Term Experiments (LTEs) in agriculture, focusing on Conservation Agriculture (CA) and Regenerative Agriculture (RA) practices. The workshop aimed to explore strategies for researchers from the national systems to come together with CIMMYT colleagues and identify ways to increase productivity, improve food security, strengthen climate resilience of agricultural systems, and enable Indian farmers and researchers to take advantage of innovations and new research in LTEs. 

The event brought together leaders from ICAR’s research divisions and institutes – including Natural Resource Management (NRM), Indian Agriculture Research Institute (IARI), Central Soil Salinity Research Institute (CSSRI) and the Research Complex for the Eastern Region (RCER) – with partner CGIAR centres CIMMYT, ICRISAT and IRRI, and others from donor agencies, private agricultural research organizations and the Borlaug Institute for South Asia (BISA). 

The event was chaired by Dr Suresh Kumar Chaudhari, Deputy Director General for Natural Resource Management at ICAR. In his remarks, Dr Chaudhari highlighted the critical role of LTEs in understanding evolving agri-food systems. He emphasized the value of revisiting past research with fresh perspectives, taking into account new knowledge, and taking a long-term, strategic view of our agricultural research portfolios.   

Dr. Prasanna Boddupalli, Regional Director for South Asia – CIMMYT, highlighted the importance of LTEs in generating knowledge for sustainable practices. He expressed hope that the workshop would inspire innovative ideas, such as the use of climate-resilient crop varieties like drought- and heat-tolerant maize, and the use of predictive analytics and machine learning to identify emerging trends  

Dr Alison Laing chaired the workshop. She outlined the objectives of the workshop and emphasize the importance of collaborative discussions in formulating guidelines and recommendations for ongoing and future experiments on CA and RA. She also highlighted the need for resource mobilization and contributions from the participating institutions.  

The opening session featured presentations by senior scientists, including Dr M.L. Jat (ICRISAT), Dr Rajbir Singh (ICAR-NRM ADG), Dr Rakesh Kumar (ICAR-RCER), Dr Madhu Choudhary (ICAR-CSSRI), Dr H.S. Jat (ICAR-IIMR) and Dr C.M. Parihar (ICAR-IARI). They provided insights into ongoing LTEs on CA and RA at their research institutions, including key research foci, discussed challenges and opportunities, and stressed the importance of ensuring the continuity of LTEs in the face of shifting priorities and donor fatigue. 

All participants then engaged in group discussions to address emerging priorities, funding challenges and barriers to implementation, and to identify ways in which LTEs can generate data to demonstrate the long-term impacts of agricultural practices and the performance of different cropping systems. These breakout sessions culminated in a plenary session where participants consolidated key issues and reached consensus on actionable recommendations. 

Dr Laing concluded the workshop by announcing that the recommendations would be compiled into a joint document to be submitted to ICAR-NRM, providing a roadmap for strengthening LTEs in India. 

In his vote of thanks, Dr Mahesh Gathala (CIMMYT) commended the participants for their valuable contributions to the objectives of the workshop’s. He expressed confidence in the collective commitment of scientists and institutions – public and private – to the advancement of LTEs and their critical role in strengthening agricultural and food system science and research.
