Can organic fertilizers rebuild Zimbabwe’s fragile soils?

“Our soils are exhausted. Even the best hybrid seed won’t yield much without nutrients. Organic fertilizers give us hope, but are they affordable and available? We need to understand our soils and make informed choices. This is an agrarian district; water isn’t scarce, but good soil is,” lamented Mrs. Munyoro, a district local authority official in Murehwa.

These words reflect a difficult reality confronting many smallholder farmers in Zimbabwe’s dryland farming regions: the urgent need to restore soil health in an increasingly fragile climate. With nearly 70% of the soils in districts like Murehwa and Mutoko classified as sandy, low in organic carbon, and prone to nutrient leaching, the potential for long-term productivity is steadily declining. Compounding this challenge is a decline in livestock populations due to disease, which reduces access to cattle manure, once a dependable source of organic nutrients.

To respond to these issues, the Resilience Building through Agroecological Intensification in Zimbabwe (RAIZ) project, led by the research consortium CIMMYT, is conducting field trials targeting soil fertility enhancement strategies that align scientific rigor with local practicality. These trials explore how conservation agriculture (CA) techniques and various organic fertility inputs—ranging from traditional manure to market-supplied products like Bokashi, Atlas orgfert (organic D), Orgfert, and Vermicompost—can sustainably improve soil fertility, structure, microbial health, and ultimately yield outcomes.

But why do these trials matter? The market is increasingly saturated with organic fertilisers, which offer both opportunities and dilemmas for smallholder farmers. From ZimEarthworms’ vermicompost, Bokashi, Orgfert, and Atlas orgfert (organic D) gaining visibility, questions remain around their affordability, accessibility, and context-specific performance. Farmers continue to rely on cattle manure where available, but rising livestock mortality, including from theileriosis (commonly referred to as January disease), is limiting this resource.

The RAIZ trials go beyond measuring yield data—they also evaluate farmer appreciation, labor requirements, and cost-effectiveness. Moreover, local authorities emphasize the importance of understanding how different organic inputs influence nutrient cycling, soil microbial activity, and overall soil fertility dynamics over time.

With several companies producing organic inputs, and cattle manure being a traditional staple, the big questions remain: What works best? What can farmers afford? And how can the findings shape broader adoption? This integrated approach is critical for guiding broader adoption of sustainable practices in Zimbabwe’s farming systems, where poor granite-derived sandy soils of low organic matter and low pH constitute up to 60% of the country’s arable land.

Insights from the Field

The farmer-led trial by Tracy Chokurongerwa in Murehwa offered compelling insights into the comparative value of organic inputs under both conventional and CA management, including intercropping setups such as maize–cowpea combinations. Treatments across plots were standardized to include five organic amendments: Vermicompost, Orgfert, Atlas orgfert (organic D), Bokashi, and cattle manure.

Bokashi showed notable improved performance compared to the previous season, while Atlas orgfert (organic D) emerged as the preferred input by farmers based on visual crop vigor and yield observations. ZimEarthworms’ vermicompost performed particularly well when combined with Compound D fertilizer, suggesting synergistic effects between organic and synthetic inputs. However, challenges with land topography and water retention reinforced the need for supporting practices such as contour ridges, stormwater diversion channels, and timely land preparation.

In another trial, one farmer tested intercropping with pigeon pea and echoed the preference for Atlas orgfert (organic D). A separate rate trial examined the impact of increasing organic input volumes, revealing a positive yield response under CA systems, although erosion risks on sloped terrain were a concern—emphasizing once again the importance of land and water management.

In Mutoko, trials faced additional variables. Termite infestation was notable in one plot, aggravated by water runoff and poor mulch management. However, plots that utilized decomposed leaf litter mulch showed better moisture retention and stronger crop establishment under conservation agriculture practices. At some sites, the differences between CA and conventional till plots were striking to all visitors, clearly demonstrating the regenerative capacity of CA-based systems.

These examples illustrate how site-specific conditions—such as slope, soil type, and mulch availability—heavily influence the outcomes of soil fertility interventions. Importantly, researchers noted that marginal land allocation for trials (often the only land farmers can offer) can limit replicability and yield potential, highlighting the tension between field research conditions and real-world farming constraints.

Highlights of the 2023/24 Season

The 2023/24 season was a year of experimentation and learning for the RAIZ project, as farmers diligently undertook the targeted trials with recommended organic fertilizer rates and conservation agriculture (CA) methods. A total of 51 farmers participated in farmer-led experiments, with 30 testing standard or recommended rates of organic amendments under CA techniques, and 21 evaluating different organic fertilizer rates. Six decentralized learning centers hosted demonstrations on maize variety performance, CA principles, sorghum, and manure use, providing a platform for peer learning and knowledge exchange.

Despite erratic rainfall ranging from 250 to 500 mm, the trials delivered critical insights into what works and where. Results showed limited maize harvests, while the trials emphasized understanding which soil amendments are most effective across different areas. This approach helps farmers avoid costly fertilizer investments by identifying locally affordable and sustainable soil enhancement options. The need for early land preparation and strategic planning at the start of the season was a key takeaway, particularly in the face of climate unpredictability and ongoing soil degradation.

Reflections from the Ground

One of the strongest messages from both farmers and stakeholders was a call for continuity. Participants appreciated the way research was embedded within farmer realities and stressed the importance of scaling the initiative. Farmer engagement from the outset, coupled with co-implementation of trials, has fostered a sense of ownership and trust.

A particularly telling observation was the presence of witchweed in conventional maize plots, reinforcing the importance of integrated soil fertility management and diversified cropping systems. Such findings not only validate CA and organic input combinations but also contribute to a growing body of evidence on how to manage parasitic weeds through ecological approaches.

With community trust, scientific insight, and early success stories in hand, the pathway to broader adoption of organic-based soil restoration strategies is becoming clearer. However, sustained support, adaptive extension services, and inclusive learning platforms will be critical to maintain momentum. For districts like Murehwa and Mutoko, soil health is the limiting factor—but with the right inputs, the right knowledge, and continued collaboration, smallholder farmers can rebuild the fertility foundation of their lands, and with it, secure the future of rural livelihoods.

Decades of on-station conservation agriculture trials reveal key farming insights for Zambia’s changing climate

Written by mcallejas on . Posted in Blogs.

Long-term research rarely offers quick fixes. More often, it is a patient pursuit, marked by seasons of uncertainty, occasional setbacks, and gradual, hard-won insights. Yet, when carefully managed, its outcomes can redefine farming systems and adaptation strategies to long-term climate trends.  

This is the story of CIMMYT‘s persistence, working alongside Zambia’s Ministry of Agriculture to maintain some of Southern Africa’s most critical long-term Conservation Agriculture (CA) experiments for over two decades. 

Scattered across Zambia’s contrasting agro-ecological zones, from the high rainfall Northern province to the drought-prone Southern Province, and the tropical savanna climate in the Eastern province, the Misamfu Research Station, Monze Farmer Training Centre, and Msekera Research Station have hosted these long-term trials, with Monze being established in 2005, Msekera in 2011, and Misamfu in 2016. Through searing droughts, erratic rainfall, floods, pest outbreaks and changing policy landscapes, these stations have systematically tested CA principles over multiple seasons, focusing on crop productivity, economic viability, and soil health, pest and disease dynamics, soil moisture and climate resilience among other aspects, to adapt CA to local farming conditions. More importantly, they have adapted these principles to Zambia’s diverse socio-economic realities and contexts. 

 

Testing CA under Zambia’s climate gradients

At the core of these trials is a simple, but essential question: “Can CA systems be adapted to Zambia’s smallholder farmer conditions to improve productivity, soil health, and resilience under climate variability?” 

Each research station offers a unique window into answering this question. For instance, Monze Farmer Training Centre located in Zambia’s Southern Province, hosts one of the oldest CA trials in the region. In addition, originally set up with eight main treatments and 32 trial plots, it has since expanded to 48 plots consisting of 12 treatments, testing CA under no-tillage against conventional plough-based systems with maize, cotton and sun hemp rotations of varying sequences. The plots have accumulated invaluable data, owing to the detailed and precise monitoring of yields, soil moisture, infiltration rates, pest and disease dynamics, soil quality indicators, and soil organic matter, year after year. 

Christian Thierfelder, CIMMYT’s Principal Cropping Systems Agronomist and founder of all long-term experiments reflects, “When we started, CA was a hot topic in Zambia. We wanted to know its benefits if you persist with these systems under Zambia’s conditions, not just for three or five years, but over decades”. 

Two decades later, key findings from these trials reveal that rotations that include cotton and/or sun hemp consistently outperform others in maize yields due to the nitrogen-fixing and soil-improving effects of the legume and deep-rooting cotton. CA plots, especially those combining minimum tillage, residue retention, and rotations, also demonstrate better soil moisture retention and infiltration, even in drought years. In fact, one striking observation has been that during intense rainfall events, water infiltration under CA plots is dramatically higher than under conventional systems, reducing flooding, erosion, and surface run-off. CA plots absorb and retain more moisture, a significant advantage as rainfall patterns become more erratic. 

However, the trials have also revealed complex trade-offs that researchers alike must accommodate. For example, while the maize-cotton-sun hemp rotation delivers exceptional yields, its economic viability hinges on market dynamics. When sun hemp seed and cotton commanded reasonable prices in the past, the system was highly profitable; in its absence, farmers risk sacrificing income for soil benefits alone. Another surprising insight comes from long-term soil organic carbon (SOC) trends. While CA systems reduce erosion and improve infiltration, the anticipated build-up of SOC has remained elusive, except at one long-term trial site outside Zambia at the Chitedze Research Station in Malawi. Thierfelder notes, “Declining rainfall, declining biomass, and declining soil carbon levels are interconnected. CA alone may not reverse these trends unless combined with complementary practices like manure application or agroforestry species.”

Adapting CA for high-rainfall areas

Misamfu Research Station, in Zambia’s wetter Northern Province, has wrestled with another challenge: CA’s performance under high-rainfall conditions. Since 2016, Misamfu has hosted the long-term CA systems trial. Originally designed to conserve moisture, CA systems, especially when planted on the flat, struggle with too much moisture, leading to waterlogging, and here, not drought, is the problem. CA plots without drainage interventions have underperformed in very wet years. Yet, new innovations are emerging. Permanent raised-beds and permanent ridges, two promising CA systems developed under irrigated systems, are showing promise by improving drainage while retaining CA’s soil health benefits. 

 “In relatively dry years, CA systems shine,” explains Thierfelder, “but under waterlogged conditions, we now know that permanent raised beds or ridges could be the missing link.” “Over the long-term, CA systems planted on the flat are capable of buffering high rainfall effects, probably due to improved infiltration”, remarked Blessing Mhlanga, CIMMYT’s Cropping Systems Agronomist.  

Capturing cumulative effects over time

Since 2011, the CA long-term experiment at Msekera Research Station in Eastern Zambia has revealed how CA performs beyond short-term seasonal gains. Unlike seasonal experiments, these trials capture the gradual, cumulative effects of CA on soil health, water use, weed and pest dynamics, and crop yields under real-world conditions. With ten treatments, including conventional tillage, ridge and furrow systems, and CA practices- such as direct seeding, residue retention, and crop rotations, the trials provide critical evidence. So far, results from Msekera show that no-tillage systems with crop residue retention, especially when combined with crop rotations, significantly improve soil moisture retention and structure, leading to more stable crop production over time. 

Why long-term matters

Long-term trials are essential to fully understand the benefits and limitations of CA across a full spectrum of climate conditions. Such trials require consistent donor support, strong partnerships with research station managers, and effective field management. Unlike short-term experiments, long-term trials capture the cumulative effects of CA practices across diverse seasons, including droughts and floods.  

These trials also show that CA is not a one-size-fits-all solution — its success hinges on continuous application over time. Since to date, rainfall patterns cannot be predicted precisely, deciding to adopt CA only in dry years is ineffective. Instead, long-term trials reveal how CA builds resilience and improves productivity year after year. 

This body of work is more than just a collection of experiments. It is a living archive, many years of climate, crop, and soil interactions, yielding insights impossible to capture through short-term trials. “We learned, for example, that infiltration rates under CA improved noticeably within just two years,” says Thierfelder. “But understanding yield trends, soil fertility dynamics or the role of rotations takes decades.” Moreover, these trials have shown that CA is not a one-size-fits-all solution. Its benefits are context-specific, often requiring adaptive management depending on rainfall, soil type, and market conditions. 

From plots to farmers’ fields

The value of this long-term work extends beyond research stations. Field days and exposure visits have allowed farmers and extension officers to engage directly with these trials, drawing lessons for their own fields. In some regions, farmers are already adapting lessons, adopting rotations, maintaining residues, experimenting with raised beds and permanent ridges, and tailoring CA to their realities. Importantly, the trials continue to evolve. While core treatments remain unchanged to preserve data integrity, small innovations, such as integrating manure or testing alternative rotations, are helping to sharpen recommendations for the next generation of CA practitioners.

The road ahead

As climate variability intensifies, the value of long-term research becomes even more critical. These trials offer answers to one of agriculture’s most urgent questions: How can CA be fine-tuned to deliver resilience and productivity? This is not just a scientific quest; it is about securing the future of Zambia’s smallholders, helping them navigate a more uncertain climate future, and ensuring their fields remain productive for the next generations. 

Women Who Nourish the Earth: Yuridia HernĂĄndez and the Feminine Strength in Sustainable Agriculture

Written by mcallejas on . Posted in Blogs.

In the lands of Oaxaca’s Mixteca, where rainfall no longer comes as it once did and the soil begins to feel the weight of years and intensive use, a network of women producers has taken on the task of healing the land—while also healing themselves. One of these women is Yuridia Hernández, who has decided to farm differently: with more awareness, less haste, and the support of other women who, like her, believe that a different kind of farming is possible. 

Since 2023, Yuridia has been part of the Secure Maize Supply Program of the Secretariat of Food Promotion and Rural Development (SEFADER), supported technically by engineer Griselda Cruz Guzmán. On her three-hectare plot, she has begun applying agroecological practices: minimum tillage, biological pest management, the use of bio-inputs, and the reincorporation of crop residues. “We’ve gone back to practices we were already forgetting. Now we see our plants are more resilient. That motivates us to keep going,” she explains.

Last year, she planted late, like many in the region, due to delayed rains. But she didn’t give up. “This is a rainfed plot, and although the weather isn’t the same anymore, we can still produce if we change how we do it,” she says firmly. Though she works alongside her husband and eldest son in a family production unit, Yuridia makes her own decisions for her plot. “At first it was difficult—he (her husband) prefers mechanized methods, using chemicals. I would tell him: ‘wait, let’s try other options.’ And though it was hard for him to give up plowing, now he sees the results. Little by little, he’s adopted new practices.” 

Like the Earth that gives life and regenerates when treated well, Yuridia has found a shared strength in other women. “In the group, you can feel when there are more women,” she says. “The men often come in with a different mindset, they find it harder to work as a team. But among women, it’s different: it’s enough to say, ‘how should we do this?’ and we organize ourselves.” She has especially formed close ties with another producer’s daughter, with whom she shares not just the work, but also a critical and forward-looking view of farming’s future: “We have that urge to do things differently, to improve them. And that’s made us a solid team. We pull each other forward—and also bring along the men who want to join.” 

What began as an individual effort has now become a small network of learning, experimentation, and mutual support. By sharing knowledge, organizing field visits, and discussing what works and what doesn’t, Yuridia and her peers have been able to strengthen themselves and those around them: “That’s how we’ve grown stronger—by building a network.” 

Beyond her own experience, she’s attended events at research platforms like those of INIFAP and CIMMYT, where she saw firsthand that sustainable practices can be applied in her context. “That’s where I said: this works, I want to replicate this,” she shares. 

Yuridia also knows that climate change is not a distant issue. “It’s hit us hard. Rains aren’t like before, pests show up suddenly. But with these practices, the system is adapting. Where we leave more residues, the plants stay vigorous.” That’s why she doesn’t hesitate to send a message to those who support research and technical assistance: “Thank you for promoting these activities. Research really does help us. It lets us change or bring back what we already knew. If we do nothing, we’ll lose our land. But if we have tools, if we see examples, we can move forward,” she says gratefully. 

Yuridia’s testimony reminds us that caring for the planet is not an abstract task—it starts in plots like hers, in voices like hers, in hands that sow with hope, science, and community. And just like the Earth, the women who care for and work the land have an immense capacity to regenerate, sustain, and transform. 

When the worm won’t wait: Battling Fall Armyworm with science, seeds and farmer-led solutions

Written by mcallejas on . Posted in Blogs.

The destructive Fall armyworm in a farmer’s field (CIMMYT)

Farmers in southern Africa face a double tragedy: drought in one season or flooded fields in another. Shredded leaves, twisted tassels, and frizzled maize cobs reflect more than just a failed harvest; they signal a deepening threat to food security and livelihoods. Compounding this hardship is the growing threat of pests and diseases, many of which are fuelled by climate change. Chief among them is the fall armyworm (FAW) (Spodoptera frugiperda), an invasive pest that arrived in Africa nearly a decade ago and continues to undermine smallholder farmers’ resilience, devouring crops stalk by stalk. 

Maize is central to food security in Zambia and Malawi, where it occupies up to 80% of cultivated land and accounts for over half of the daily calorie intake. In Zambia alone, more than 90% of smallholder households grow maize, underscoring its economic and political weight. Yet, in recent years, farmers have had to contend with losses not just from erratic rainfall and poor soils, but from pests and diseases that seem to multiply with each season. 

A recent CIMMYT-led study across 1,100 farming households in Malawi and Zambia, as part of the Southern African Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, highlights the long-recognized challenge of FAW damage. The study confirms that FAW is not only persistent but also costly. During 2023/2024 season, 70% of surveyed farmers reported FAW damage to their maize fields. On average, FAW infestations resulted in a 13.5% to 30% reduction in maize yields, translating to more than 230 kg of lost grain per hectare. Other crops were also heavily affected, with the rosette virus reducing groundnut yields by 27% and soybean rust causing up to 25% losses in soybean fields. 

The effects of FAW extend beyond crop harvests. It has also been shown to significantly undermine household income and food security. Although the 2023/2024 losses are slightly lower than earlier estimates, which ranged from 22% to 67% across Africa, they are still substantial enough to affect food security and livelihoods. Furthermore, the combined effects of FAW, rosette disease and rust had large income and food security impacts.  Households facing the triple burden of these pests and diseases – FAW, groundnut rosette virus and soybean rust on their three most important crops are twice as likely to experience food insecurity as compared to experiencing just one of these threats.  

In response, many farmers are turning to pesticides, improved seeds and crop rotation. However, as the data indicates, pesticides alone are far from being a comprehensive solution. They are often costly, frequently misapplied, and carry significant risks to both human and the environment. Moreover, FAW is increasingly developing resistance to commonly used pesticide formulations. Access to agricultural extension services remains limited: only 27% of surveyed farmers in Zambia and 54% in Malawi reportedly receiving such support. Without proper guidance on when and how to apply pesticides, their misuse can end up doing more harm than good. 

These findings highlight a broader challenge: the urgent need for sustainable, science- and data-driven solutions that are practical for farmers. At the core of the response is a new generation of maize hybrids with tolerance to FAW. CIMMYT in collaboration with its partners using conventional breeding has developed new generation of hybrids with native genetic (non-transgenic) tolerance to FAW. The breeding process is complex, requiring years of field testing across diverse agroecological zones to ensure adaptability and performance. 

In 2023, three FAW tolerant maize varieties developed by CIMMYT were officially released by the Zambia Agriculture Research Institute (ZARI) and sub-licensed to seed companies for commercialization. With support from AID-I and the CGIAR Sustainable Farming program, CIMMYT and partners are actively promoting these hybrids among smallholder farmers. The AID-I project has provided critical support to accelerate seed production of these hybrids. Zamseed and AfriSeed are leading efforts to bring these varieties to market.

Through the Sustainable Farming program, on-farm trials have been established across three agroecological gradients in Siavonga, Mazabuka, and Mbala districts to test the performance under farmer conditions and understand their impact on farmer outcomes. There are two treatments, which include growing the FAW-tolerant maize variety alone, and intercropping it with other legumes. Rather than assuming a one-size-fits-all solution, CIMMYT is using randomized control trials (RCTs) to assess the real-world performance of these varieties under varying conditions. The goal is not only to validate the science but to build a stronger case for scaling. 

In Siavonga, where high temperatures and erratic rainfall create ideal conditions for FAW outbreaks, early results show promising benefits from using FAW-tolerant maize varieties. Preliminary foliar damage assessment indicates significantly reduced infestation levels compared to susceptible varieties. In contrast, the benefits in Mazabuka are less pronounced, while in Mbala – a cooler, higher-altitude location with lower pest pressure- no major gains have yet been observed. These location-specific findings are critical for informing hyperlocal, evidence-based policymaking.  Equally important is building awareness and trust among farmers, ensuring they know these improved varieties exist and understand how to grow them applying good agronomic practices. Through AID-I, CIMMYT is working to close that gap, demonstrating the business case for investing in FAW tolerant maize seed to the private sector, and equipping farmers with knowledge that goes beyond what is in the bag.  

For example, a survey carried out in Malawi, Tanzania and Zambia revealed that awareness of FAW-tolerant maize varieties remains low, with only 19% of farmers in Malawi, 34% in Tanzania and 39% in Zambia had heard of FAW-tolerant maize varieties. This underscores the urgent need to scale up awareness campaigns and initiatives to stimulate demand. Encouragingly, among the farmers who are aware of these varieties, the majority expressed a willingness to purchase them at prices comparable to those of other hybrid maize varieties. This indicates a strong business case for private sector investment in seed multiplication and distribution to meet potential demand and expand access to FAW-tolerant maize hybrids. 

For many farmers in Southern Africa, the FAW remains a persistent threat. However, through science, strong partnerships, and a commitment to field-based evidence, the tide is turning, one trial, one variety, one growing season at a time. 

Evangelina Villegas: A Pioneer Woman in Agricultural Science, Inspired by Norman Borlaug

Written by dmedina on . Posted in News.

Norman Borlaug was awarded the Nobel Peace Prize in 1970 for leading an agricultural revolution in Mexico, specifically in the Yaqui Valley in Sonora, where he developed high-yield, disease-resistant wheat varieties that helped save the lives of thousands threatened by hunger.

His legacy, driven by CIMMYT in collaboration with the Government of Mexico, has had a profound and lasting impact on global food security. This legacy has inspired and empowered the role of numerous women in agricultural science, encouraging them to lead innovative and essential research to address global food challenges. 

Among the women who have stood out due to this influence is Evangelina Villegas, a Mexican scientist whose pioneering work in nutritional maize improvement had a global impact. Together with Dr. Surinder Vasal, Villegas developed quality protein maize (QPM), an innovation that significantly reduced malnutrition and improved nutritional quality for millions of people in developing countries. For these contributions, Evangelina Villegas was awarded the World Food Prize in 2000, becoming the first woman to receive this prestigious honor. 

Beyond her scientific achievements, Evangelina Villegas stood out for her commitment to mentoring new generations of researchers, especially women. Her efforts opened doors for more women scientists to participate in high-impact social projects, establishing her as a role model for female leadership in agricultural science. 

Villegas’s career clearly reflects the continuation of the social and scientific commitment initiated by Borlaug. Her example highlights how his legacy has not only positively influenced science but also played a crucial role in advancing gender equity within the agricultural and scientific sectors.

How Crops to End Hunger is transforming CGIAR crop breeding from the ground up

Written by dmedina on . Posted in Blogs.

When crop breeding succeeds, the impact is dramatic: improved varieties reach farmers, productivity increases, and resilience to climate change and disease improves. But breeding success doesn’t happen by chance. It relies on modern facilities, cutting-edge tools, and the ability to test and select for complex, evolving traits. That’s where Crops to End Hunger (CtEH) comes in. At CGIAR Science Week, the project team and beneficiaries demonstrated how.  

A project designed for exponential impact 

Launched in 2019, CtEH aimed to support the modernization of CGIAR’s crop breeding infrastructure, with support from GIZ, the Gates Foundation, the US government, DFID, and ACIAR. As it nears the end of the most recent two-year GIZ funding cycle, the project has made targeted investments in upgrading breeding station infrastructure, equipping them with advanced tools, building capacity across CGIAR and national breeding teams, and developing the foundational systems needed to accelerate the entire breeding process. 

Supporting CGIAR Centers’ core functions 

At CGIAR Science Week, Bram Govaerts, CIMMYT Director General, explained: “CtEH is crucial for implementing CIMMYT 2030 strategy. Support has increased our breeding capacity for maize, wheat, and newly added dryland crops that complement maize and wheat cropping systems.” 

One example is the Groundnut Biotic Stress Screening Network, established with CtEH support. The network has strengthened the capacity of partners in Uganda and Malawi to screen for groundnut rosette disease; a devastating disease spread by aphids can result in 100% crop loss, with annual losses of over $150 million. The screening network will enable development of resistant varieties. 

In Kenya, a $2.5 million worth infrastructure upgrade at the KALRO–CIMMYT Crop Research Facility in Kiboko, has accelerated breeding cycles. This investment is enabling the development of new varieties tailored to the needs of East African farmers. Drought-tolerant maize varieties developed through work in Kenya and Zimbabwe have expanded dramatically, from just 0.5 million hectares in 2010 to 8.5 million hectares across sub-Saharan Africa today. 

The Kiboko station is also a regional leader in pest and disease resistance. Its advanced screening capabilities for fall armyworm have led to the release of three tolerant maize hybrids, benefiting farmers in Kenya, Malawi, Zambia, Zimbabwe, South Sudan, and Ghana. The development of maize varieties resistant to maize lethal necrosis further demonstrates the station’s critical role in enhancing food security across the region. 

Operational improvements: more than bricks and mortar 

CtEH isn’t just about infrastructure; it’s also about operational transformation which profoundly change the breeding work. For instance, as Gustavo Teixeira explains, “The installation of reliable irrigation systems, one of CtEH’s key priorities, improves breeding efficiency in several ways. It enables off-season trials, allowing breeders to conduct multiple generations per year. It promotes plot control, ensuring uniformity across trial plots and data quality. Finally, it improves the ability to breed for drought tolerance.” 

In Ghana, Maxwell Asante of CSIR-CRI described how CtEH brought crop-neutral upgrades that have encouraged teams to strategically plan and align resources, enabled cost attribution to specific breeding programs, improving accountability, and fostered cross-location collaboration by making centralized services possible.  

These operational improvements are helping CGIAR and national systems move toward truly modern breeding programs that can operate with greater precision, speed, and coordination. 

Building for regional collaboration and innovation 

Bram Govaerts also emphasized that collaboration is central to the future of breeding, and that CtEH is helping to make that possible. 

“Strategic collaborations enhance our impact by leveraging diverse resources and expertise, especially through public-private partnerships that scale research and technology transfer for agricultural transformation.” 

Facilities and systems funded by CtEH are helping CGIAR foster cross-disciplinary innovation and strengthen ties with governments, donors, and technology companies. This makes it easier to bridge the gap between research and real-world application – exactly what’s needed to accelerate impact. 

Empowering women in breeding 

Infrastructure improvements under CtEH have considered inclusivity and gender equity. 

Aparna Das, CIMMYT Technical Lead, explained that modernized stations have been upgraded to better support women in breeding roles – such as providing restrooms and expression rooms in remote research stations, often located far from urban centers, which help attract talent. 

Why does this matter? Women breeders bring valuable perspectives, particularly in identifying gender-relevant traits, like cooking time, seed size, and ease of harvesting. Diverse, balanced breeding teams also tend to be more dynamic and innovative, leading to better science and more relevant products for farmers. 

Targeting the right traits 

Breeding for traits farmers need starts with the ability to test and measure those traits under real-world conditions. This can require specialized equipment. 

Maxwell Asante emphasized that this is where CtEH makes a difference: 

“Testing for traits is fundamental. And now, we’re not just selecting for yield – we’re breeding for disease resistance, climate resilience, cooking quality, and more. The only way to do this efficiently is through modern breeding infrastructure and processes.” 

Modern breeding enables scientists to combine multiple traits in a single variety and identify the best candidates with greater accuracy and confidence. This is made possible through CtEH investments in equipment and data analytics, such as Bioflow, the CtEH-funded breeding analytics pipeline developed for CGIAR and its partners. 

Long-term impact through smart design 

What makes CtEH unique is its sustainability-by-design approach. The project was structured to build long-lasting capacity and to leverage investments from across CGIAR Initiatives, amplifying both the quality of upgrades and their outcomes. 

Whether it’s enabling year-round trials, supporting new partnerships, or empowering a more diverse generation of breeders, CtEH is not just upgrading infrastructure, it’s also reshaping CGIAR and partners’ breeding. 

As CGIAR continues to respond to climate, nutrition, and food security challenges, projects like CtEH are making sure we have the tools, systems, and people in place to breed for tomorrow – starting today.

CIMMYT and WorldVeg Unite for Better Nutrition and Farmer Incomes

Written by dmedina on . Posted in Press releases.

MEXICO CITY — CIMMYT and the World Vegetable Center (WorldVeg ) accelerated its global partnership by launching a new WorldVeg office in Mexico at CIMMYT’s headquarters. This joint location will provide improved nutrition, soil health and earning potential for global farmers.

“When vegetables and cereals grow together, the benefits multiply for people and the planet,” said Bram Govaerts, Director General of CIMMYT.

Govaerts said he is eager to scale a proven global track record of collaboration across Mexico, Latin America and the wider world. CIMMYT and WorldVeg’s partnership is already delivering results in Mexico and Central America. For years, the organizations have collaborated to improve production in the traditional milpa system—where maize is grown with beans and squash, often known as the “three sisters.” Collaboration increased yields, helped balance diets and conserved biodiversity.

The collaboration also builds on the more than 100,000 people reached in Sudan, Malawi, Tanzania, and Zambia through CIMMYT and WorldVeg collaboration. These joint projects have improved dietary diversity, soil health and incomes by cultivating both vegetables and cereals. In Tanzania alone, the collaboration has increased the sales of value-added products by 50%.

“This partnership represents tangible, scalable diversification options for farmers,” said Marco Wopereis, Director General of WorldVeg. “Integrating vegetables into cereal systems improves nutrition, raises incomes, and builds sustainability, beginning in Mexico and expanding globally.”

Led by WorldVeg Scientist Roland Schafleitner, the WorldVeg Mexico office in partnership with CIMMYT, local universities, research organizations and farmers will identify and promote adapted vegetable varieties suitable for smallholder production, as well as intercropping systems.

This initiative will improve supply of nutrient-rich vegetables that directly address the pressing global challenge highlighted by a 2020 FAO report—that over 3 billion people worldwide lack affordable access to diverse and nutritious diets.

“Whether it is in the field or on plates – cereals and vegetables go better together,” said Govaerts. “This marks an acceleration CIMMYT’s efforts to work with other organizations that share in our mission to advance a more food- and nutrition-secure world for all. We are eager to partner with other organizations that share this focus.”

The strategic alliance between CIMMYT and WorldVeg marks the first of several anticipated collaborations, transforming CIMMYT’s global headquarters into a hub for food and agricultural innovation.

Fidelia GonzĂĄlez Galindo, a rural woman who challenges limits and transforms the countryside

Written by dmedina on . Posted in Blogs.

From the Sierra Norte of Puebla, Fidelia González Galindo has built her story with determination and courage. At 48 years old, González Galindo is responsible for the Cuautempan Research Platform in the state of Puebla and is part of CIMMYT’s Hub Valles Altos. Her work focuses on improving food security and strengthening native maize production—a mission born from her own struggle to access education.

Research platforms, like the one Fidelia coordinates, are spaces where innovative technologies are developed and validated to enhance agricultural production. These platforms explore improved farming practices, efficient soil and water resource management, and strategies for sustainability and food security. Through her work in Cuautempan, Fidelia strives to ensure that these innovations reach rural communities and are adapted to the real needs of women farmers.

Raised by her grandmother in a community where it was considered normal for women to dedicate themselves to the home and marriage, Fidelia defied these norms—challenging even the authority of the matriarch in her household. With her mother’s support, she pursued a different path, continuing her studies and eventually attending the Autonomous University of Chapingo. There, she faced not only academic challenges but also discrimination due to her Indigenous background and her status as a woman in a male-dominated field. “I never accepted that being a woman was a limitation,” she recalls.

Since returning to her region, Fidelia has tirelessly advocated for the autonomy of rural women, who often take charge of farming while men migrate in search of work. She has witnessed firsthand the challenges they face: limited access to quality seeds, financial constraints, physical disadvantages in labor-intensive tasks, the constant struggle to feed their families, scarce training opportunities, and the overwhelming burden of balancing household responsibilities with agricultural production. “Many times, women have to find additional jobs to support their families, which takes them away from improving their farming systems,” she explains.

To address the many challenges faced by rural women, Fidelia promotes knowledge-sharing on sustainable agricultural practices and works to empower women in decision-making processes. She has helped create support networks among women farmers, facilitated knowledge exchange, and organized training sessions with flexible schedules to accommodate family responsibilities. She also advocates for municipal and government support to fund productive projects, enabling women to generate income independently. “Knowledge is power, and if women learn to manage their resources, they can transform their lives and their communities,” she says.

Fidelia describes rural women as hardworking individuals, proud of their roots and committed to making meaningful changes in their environment. “They are bold women who, when they learn something new, apply it with determination. And the best part is that they don’t keep the knowledge to themselves—they share it with others so that everyone can improve,” she emphasizes. Beyond producing food, these women care deeply about their families’ health, soil conservation, and their children’s future.

Fidelia represents the relentless efforts of rural women who challenge the limits imposed by society. “Farming is not exclusive to men,” she declares with conviction. Her story is a testament to resilience, learning, and transformation. Through her work, she cultivates not only maize but also hope, knowledge, and a more equitable future for women in agriculture—proving that true change begins when women are empowered to lead from the land they know best.

Reinventing mechanization for Southern Zambia’s drylands: The story of Joe Akombaetwa

Written by dmedina on . Posted in Blogs.

In Dumba Camp, a small farming community in Mazabuka District, Joe Akombaetwa is proving that even in the face of unreliable rains and poor soils, small shifts in how farmers work the land can make all the difference. A farmer since 1992, Joe has lived through the growing impacts of climate change, its frequent shocks to the rain-fed systems, and the high risks it brings to farming families in Zambia’s Southern Province. For the past five years, he has worked as one of the earliest mechanization service providers (SPs) under the European Union-funded Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project. As a SIFAZ service provider, Joe acquired a set of machinery, including a two-wheel tractor, a trailer, a multi-crop thresher, and a sheller in 2021. Since then, he has been offering paid mechanization services to farmers in his community. But more than a service provider, Joe is an innovator, a machinery fabricator, and a businessman, creating tailor-made climate-smart mechanization solutions with the support of the SIFAZ project, responding directly to the challenges faced by farmers in his community.

Grounding innovation in reality

Joe’s innovations aren’t conceived in a lab—they’re forged in the field, shaped by the lived realities of his fellow smallholder farmers. One of his earliest breakthroughs came when he collaborated with SIFAZ engineers to design a T-bar to modify the Chinese single-row, no-till multi-crop planters into a double-row planter for a two-wheel tractor, allowing simultaneous planting of two rows instead of just one.

The original single-row planters, while functional, were slow and inefficient. “We wanted to save time and get the work done faster,” Joe explains. “So, we created the T-bar so that two planters could work together in tandem.”

But the innovation didn’t stop there. Joe received feedback from the farmers on the issue of high side separation between the seed and fertilizer openers on the planter. This high side separation of about 120 mm might be useful to reduce seed burning in an irrigated system for which the planter was developed, but Joe and his client farmers in the rain-fed system noticed reduced early plant growth, evidently resulting from delayed nutrient access by young seedlings of the crops. Further, the furrow covered by the press wheels of the planter was not optimum (leaving some seeds uncovered with soil), leading to germination failures.

With his own hands and tools, together with the SIFAZ engineers, Joe redesigned the seed placement system by better aligning the seed and fertilizer openers (with 50 mm side separation) and developing a flexible seed-covering kit fitted before each press wheel on the planter. These modifications addressed what agronomists refer to as “placement efficiency”, but for Joe, it was simply about “getting the seed and fertilizer placed close to each other for the plants to access the fertilizer early and firmly cover the seeds for optimum emergence.” To further improve performance, he added a balancing bar to help stabilize the planter across uneven ground, making the machine more practical for Southern Province’s uneven terrains and varying soil textures.

Bridging science with farmer-led solutions

Joe’s hands-on creativity is not new. Back in 2010, he was part of the team that co-developed an animal-drawn ripper, a widely adopted tool that aligns with Conservation Agriculture (CA) principles by reducing soil disturbance.

With a background in blacksmithing and metal fabrication from Kasisi, and early career exposure to seed certification at ACCI in Chilanga, Joe has long moved between formal agriculture and on-the-ground adaptation. Joe is aware of declining draft animals and the aging of the farmers in Zambia, which adds to the challenges faced by smallholder farmers. He sees a declining interest of rural youths in agriculture who do not want to walk behind the beasts or do labor-intensive manual work. Observing the ease with which large-scale commercial farmers operate rippers and boom sprayers, Joe wondered, “Why not adapt this to smallholder needs?”

Joe designed a double-row ripper and a mini boom sprayer for use with a two-wheel tractor. Compared to the traditional animal-drawn single-row rippers or the knapsack sprayers, the two-wheel tractor double-row ripper saves not only time, costs, and drudgery, but also makes farming interesting. “In just ten minutes, I can finish spraying a 16 m by 39 m field,” he says. It’s a leap in efficiency, and for farmers, who often juggle time, labor, and resource constraints, it’s a game-changer! Joe has sold a few rippers and boom sprayers to his neighboring farmers and different projects. The demand for the machinery is on the rise, which encourages him as a rural manufacturer.

Business with a purpose

Joe isn’t only an innovator; he’s also a sharp businessman. From ripping and planting to boom spraying and shelling maize, his mechanization services are in high demand among farmers in and around Dumba Camp. “Ripping has been the most profitable,” he notes. “Almost every farmer now wants it because of the sustainable farming practices introduced by SIFAZ.” He charges based on plot size and crop type, typically around ZMW 200–450 per hectare (approximately US$7–16) for services like no-till planting. But he also knows the realities farmers face. “Sometimes, I negotiate. I don’t want the price to scare away the farmers.” Demonstration days and field shows are his marketing lifeline. From the Cotton Development Trust-organized mechanization field days to local radio promotions, Joe has built a network of trust and visibility. He’s become a go-to name in the Dumba Camp and beyond.

Staying afloat in tough seasons

Last season, the El Niño-induced drought was a huge blow in farmers’ fields. Poor and uneven rainfall and economic strain slashed demand for mechanization services. But Joe stayed afloat by leaning on his farmer instincts. He didn’t sell off all his harvest, but instead, he stored 100 bags of maize and sold another 100 bags to have money for living. That food sovereignty, paired with diversified income from shelling and ripping, kept his business breathing through the drought.

A legacy in the making

Behind the machines and modifications is a father of five, two of whom are already following in his footsteps, bringing civil engineering skills into the family’s growing innovation portfolio. It’s a quiet generational shift powered by resilience, knowledge sharing, and an openness to adapt. Joe’s story reminds us that the future of farming isn’t only shaped by distant policies or global climate models, but also built, welded, and tested in the fields of Southern Zambia, where farmer-innovators like Joe bridge the gap between science and local adaptation.

Munich Statement on Agriculture, Biodiversity and Security: there is no security without food security

Written by dmedina on . Posted in News.

In February 2025, leading voices in the global food and agricultural system came together on the occasion of the Munich Security Conference to discuss how to achieve food security in an increasingly insecure world.

Biological diversity is key to food and nutritional security, but all too often neglected. The loss of agricultural biodiversity (which includes crop diversity) threatens not just the resilience of global food systems but also their productivity. This in turn undermines rural livelihoods and economic activity, increasing the likelihood of migration. It also heightens the risk of price spikes and restricts the availability of staple food products, which may hamper trade in important commodities as governments seek to shore up sufficient stockpiles for domestic markets.

Compromised food systems and agricultural biodiversity loss destabilize and damage communities, potentially to an existential level, while preserving agricultural biodiversity and investing in resilient farms are the foundations for peace and prosperity.  Stakeholders across the international community, including the security community, civilian agencies, civil society and businesses, should act to preserve and use agricultural biodiversity and promote sustainable agriculture by putting farmers first.

As the ultimate providers of life-sustaining nutrition, farmers are indispensable global security partners. Farmers provide a steadying economic force, but only if they have adequate safety, and access to land, investment, innovation, and functioning markets. It is imperative to provide farmers with the support, investment, and opportunities for innovation to adapt to changing global environmental conditions and persevere through social unrest and conflict. Farmers must be able to employ agricultural practices that concurrently promote nutrition, water security, human health, and biodiversity preservation. Prioritizing the delivery of nutrient-rich foods and bio-based products in ways that respond to water and weather stress is essential.

Crucially, for farmers to be successful, they need continued access to agricultural biodiversity. To ensure that, genebanks must be seen as a shared strategic strength.

Reliable, sufficient, and nutritious food for the current and future population depends on the crop diversity that underpins critical research and breeding efforts. Despite its increasing importance in light of a changing climate, the conservation and availability of crop diversity is increasingly at risk: it is declining in farmers’ fields and in the wild, and genebanks are chronically underfunded. Growing food demands, land degradation, and geopolitical tensions threaten crop diversity, and more generally agricultural economies.

Given their essential role in food security, genebanks should be strategically protected and funded. Sufficient attention and resources should be available to ensure an effective and efficient global system of genebanks under the policy umbrella of the International Treaty on Plant Genetic Resources for Food and Agriculture. In addition, the security community should incorporate food security and agricultural biodiversity into national and international security risk assessments and strategies.


Call to Action

It is our duty to alert the world to the threats to security and state stability posed by compromised food production systems and the loss of agricultural biodiversity. We wish to highlight the need for greater attention and investment from all stakeholders across governance, including the security sector, as well as civil society and the private sector.

Leading international organizations in agricultural biodiversity conservation and agricultural research, philanthropies, multinational corporations, and representatives from governments share this concern and endorse this statement arising from discussions at the 2025 Munich Security Conference.

Scaling conservation agriculture: Victor Munakabanze’s journey from trials to transformative adoption

Written by dmedina on . Posted in Blogs.

Each annual field tour offers a fresh perspective on the realities farmers face. It’s a window into how different agroecological conditions shape farming experiences and outcomes, revealing what works in farmers’ fields and what doesn’t under an increasingly unpredictable climate.

This year, in Zambia’s Southern Province, the story is promising, as good rains have set the foundation for a favorable crop—a stark contrast to the past season, marked by the El Niño-induced drought.

In the Choma district’s Simaubi camp, Conservation Agriculture (CA) trials paint a picture of resilience and adaptation. The area experiences a semi-arid climate with erratic rainfall averaging 600–800 mm annually, often prone to dry spells and drought years, such as the last, when only 350–400 mm were received. The soils are predominantly of sandy loam texture, with low organic matter and poor water retention capacity, making them susceptible to drought stress.

The area around Simaubi hosts seven mother trials, where a wide range of technologies are tested, and 168 baby trials, where a subset of favored technologies are adapted to farmers’ contexts. Each trial tests different maize-legume intercropping and strip cropping systems against conventional tillage-based practices. As adoption steadily rises, more farmers are experiencing firsthand the benefits of sustainable intensification.

A Champion in the Making

Meet Victor Munakabanze, a farmer with decades of experience and a passion for learning. He began his CA journey as a baby trial implementer, experimenting with the four-row strip cropping system on a 10 m by 20 m plot, with four strips of ripped maize and four strips of ripped groundnuts. Starting in the 2020/21 season—despite a slow start—he persevered. Instead of giving up, he and his wife embarked on a learning journey that led them to scale up and champion CA technologies in their community.

Victor has been part of CA trials under the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project in the Southern Province for five years and has seen the power of small steps in driving change. His initial trial plots sparked hope, showing him that improved yields were possible even under challenging conditions. Encouraged by these results, he expanded his CA practices to a 1.5-hectare plot during the 2024/2025 cropping season, investing in his farm using income from goat sales. He successfully integrated livestock within the cropping system, using goat manure to complement fertilizers—an approach that has not only improved soil fertility but also strengthened the farm’s sustainability.

From Experimentation to Expansion

Victor’s decision to adopt CA at scale was driven by tangible results. He found that intercropping maize and groundnuts in well-spaced rip lines could optimize overall yields better than conventional methods.

However, the transition wasn’t without challenges. In the first season, he started late and harvested little. The following year, delayed planting resulted in just four bags of maize from the 200 mÂČ. The El Niño event during the 2023/24 season wiped out his harvest completely. But through each setback, he refined his approach, improving his planting timing and weed management by incorporating herbicides when needed.

Now, his farm serves as a learning hub for fellow farmers from the surrounding community in Simaubi camp. They are drawn in by his success, curious about his planting techniques, and impressed by his ability to integrate crops and livestock. With 23 goats, a growing knowledge base, and a determination to share his experience, Victor embodies the spirit of farmer-led innovation. His story is proof that CA can be practiced beyond the trial plots—it is about ownership, adaptation, and scaling what works.

Inspiring Adoption, One Farmer at a Time

Victor’s journey highlights a crucial lesson: when farmers see the benefits of CA on a small scale, they are more likely to adopt and expand these practices on their own. His resilience, coupled with a keen eye for what works, has made him a role model in his community. From testing to real-world application, his success is growing evidence of the replicability of CA technologies. As adoption spreads, stories like Victor’s pave the way for a future where sustainable farming is not just an experiment—but a way of life.

Wheat plays a pivotal role in Ethiopia’s agricultural landscape. As the country’s second most important staple crop, it is crucial to national food security. Traditionally, wheat cultivation has been concentrated in Ethiopia’s highlands, but this has changed with the introduction of the ADAPT-Wheat project—an initiative designed to address the production challenges faced by Ethiopia’s irrigated lowland areas. Led by CIMMYT in partnership with the Ethiopian Institute of Agricultural Research (EIAR), the project aims to tackle key issues such as the lack of stress-tolerant wheat varieties and limited access to reliable seed sources.

Transforming wheat farming in Ethiopia’s lowlands

The Adaptation, Demonstration, and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project focuses on bridging critical wheat production gaps and introducing innovative solutions for smallholder farmers, particularly in the Afar and Oromia regions. By improving wheat production through new varieties and modern technologies, the project is not only increasing agricultural productivity but also transforming farmers’ livelihoods. The initiative aims to directly benefit 1,000 households, with a much wider impact expected across the two regions.

Financially supported by BMZ, the project aligns with Ethiopia’s broader goal of achieving food self-sufficiency. Researchers and national partners have witnessed a significant shift in wheat production practices, demonstrating the success of innovative agricultural technologies and improved collaboration among stakeholders.

Insights from researchers and partners

Bekele Abeyo, CIMMYT-Ethiopia Country Representative and project leader:

“The ADAPT-Wheat project marks a major milestone in Ethiopia’s wheat production journey. It introduces viable wheat technologies that are well-suited for the irrigated lowlands, enhancing both production and productivity in the pursuit of food and nutritional security.” 

Tolossa Debele, senior researcher and EIAR–DG representative:

“For years, CIMMYT has been instrumental in advancing Ethiopia’s wheat production system by introducing germplasm, improving varieties, and offering financial, equipment & technical support and training for both researchers and farmers. With the ADAPT-Wheat project, we’ve seen another tangible difference in the livelihoods of smallholder farmers, particularly in the Afar and Oromia regions. The project’s support, including the introduction of modern farm machinery, has not only enhanced mechanization at the farm level but has also contributed significantly to the broader objectives of national agricultural development.”

Major milestones and achievements

1. Building capacity for sustainable change

One of the project’s most significant accomplishments has been its strong emphasis on capacity building—both human and physical—to empower local communities in wheat farming. Key capacity-building initiatives include:

  • Training for researchers: Software and scientific writing training to enhance technical skills and scientific contributions.
  • Training of trainers (TOT) for agricultural experts: Development agents and district-level subject matter specialists were trained to share knowledge with farmers.

The project also included seed distribution, experience-sharing visits, and field days to disseminate knowledge and encourage peer learning. A notable outcome has been informal seed exchange among farmers, amplifying the project’s impact.

Through these efforts, the project successfully reached approximately 4,300 households and engaged a wide range of stakeholders, contributing to human capacity development, seed production and distribution, technology diffusion, and sustainable farming practices.

Additionally, infrastructure development—such as the construction of a quarantine facility and installation of air conditioning units at the Werer Research Center—has strengthened research capacity and maintained high standards for agricultural innovation. The procurement of essential farm machinery has also set the stage for more sustainable wheat farming in Ethiopia’s lowlands.

2. Introducing elite wheat lines

The project introduced 505 elite bread wheat lines and 235 durum wheat lines. From these, 111 bread wheat and 49 durum wheat genotypes were identified for their promising traits, including heat stress tolerance, early maturity, and superior yield components. These lines were rigorously tested across diverse agroecological zones to ensure adaptability.

3. Demonstrating modern irrigation technology and mechanization

The project didn’t stop at improving wheat varieties—it also introduced modern mechanization practices to enhance efficiency and yield. In the Afar and Oromia regions, pilot farms demonstrated advanced machinery such as:

  • Subsoilers
  • Bailers
  • Land levelers
  • Planters
  • Ridge makers
  • Multi-crop threshers

These technologies have been showcased at various farm sites to facilitate adaptation and scaling.

4. Releasing and adapting wheat varieties

The project identified eight wheat varieties (four bread wheat and four durum wheat) suited for Ethiopia’s lowland irrigated conditions.

Additionally, two new wheat varieties—one bread wheat and one durum wheat—were officially registered and released for large-scale production. These releases mark a significant milestone in Ethiopia’s efforts to strengthen wheat production systems.

5. Seed production and distribution

Ensuring the availability of high-quality seeds has been another key priority. Through partnerships with research centers, early-generation seeds were provided to private seed producers and farmers’ cooperative unions. Field monitoring ensured seed quality at harvest, resulting in the production of 430 quintals of certified seed.

Women and youth empowerment strategy

The ADAPT-Wheat project has made a deliberate effort to empower women and youth by ensuring they have access to high-quality seeds, training, and technical support. Notably, women comprised 32% of seed distribution beneficiaries, strengthening their role in improving food security and livelihoods.

Voices from the field: Farmers share their stories

Damma Yami’s story is a powerful example of how innovative agricultural initiatives can transform communities, especially in regions facing harsh environmental conditions.

“For many years, we have lived in arid conditions where livestock farming was our primary livelihood. However, with the challenges posed by weather trends, our traditional systems were no longer sufficient to maintain our livelihoods. The introduction of the ADAPT-Wheat project in recent years has reversed this trend. The project brought us wheat cultivation, as a new and golden opportunity for the farming community. We received high-yielding seeds, training, and technical support on farming practices, and soon we began to see impressive results. The benefits of the project are clear: it provides food for our families, generates income to send children to school, and helps meet other basic needs. As a farmer who engaged in this project, I can confidently say that the project has reshaped our future livelihood.”

Yeshiwas Worku, a 40-year-old farmer was among those who benefited from the project.

Yeshiwas explains that before the project, wheat cultivation was not traditionally practiced in his area, but it has now become a game-changer for the community. The introduction of modern farming tools, machinery, and access to improved crop varieties has been key to their success. With the help of the project, wheat production has not only become their main source of income but has also helped farmers gain confidence in their ability to sustain their livelihoods.

“We are now familiar with modern farming tools, machines, and practices thanks to the implementing partners of the ADAPT project. We also have access to improved crop varieties, which are crucial for better production and increased income. Now, wheat production has become the main source of our livelihood. This alternative farming opportunity has not only boosted our confidence but has also allowed us to secure a more sustainable livelihood for my family and me. I am deeply grateful to the project implementing partners for playing such a crucial role in transforming our lives. The impact has truly been transformative.”

A transformative impact on wheat production

The ADAPT-Wheat project, alongside CIMMYT’s ongoing work in Ethiopia, has significantly improved wheat production systems and enhanced the livelihoods of smallholder farmers in the lowland regions. More than just a This project is technological intervention, the project serves as a lifeline for smallholder farmers. By introducing innovative wheat technologies, improving seed availability, and empowering local communities, it directly contributes to Ethiopia’s food security goals while fostering economic growth and resilience in rural areas.

As Ethiopia continues its journey toward agricultural self-sufficiency, the success of the ADAPT-Wheat project serves as a model for sustainable agricultural development.

Bridging borders: A South-South exchange between Ethiopia and Nepal to tackle soil health challenges

Written by dmedina on . Posted in Blogs.

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.

Seeds of change: How QDS is transforming smallholder farming in Tanzania

Written by dmedina on . Posted in Blogs.

In Tanzania, access to high-quality seeds has significantly benefited smallholder farmers by improving their livelihoods. Despite impressive economic growth, poverty reduction has not kept pace, and malnutrition rates remain a challenge.

The Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project, funded by the Bill & Melinda Gates Foundation (BMGF), led by CIMMYT, and implemented in Tanzania by the Syngenta Foundation for Sustainable Agriculture (SFSA), is an excellent example of the positive impact of supporting smallholder farmers by ensuring seed availability, access, and affordability.

Tanzanian smallholder farmers face challenges in increasing yields and incomes due to a lack of affordable, high-quality seeds, inadequate agronomic training, and limited access to reliable markets. Distance from seed suppliers and agro-dealers, along with impassable roads, exacerbate the situation. In addition, the distribution networks of private companies that produce certified seeds are very limited, especially for underutilized crops.

The Quality Declared Seeds (QDS) system is a seed production system that ensures seed meets a minimum quality standard through inspection by an official seed certification system or a designated inspector from the local government authority. SFSA, through the AVISA project, is focusing on supporting the production of QDS by community-based groups for common bean and groundnut varieties in several districts in Tanzania.

Two QDS-producing farmer groups received free Early Generation Seed (EGS) capital, consisting of 200 kg of Selian 13 bean seed, 150 kg of Tanzanut seed, and 50 kg of Naliendele 2016 groundnut seed. As a result, the groups sold 1.35 MT of QDS for common beans and 2.00 MT of groundnuts to individual farmers in the Karatu and Bahi districts respectively.

“This initial investment by the AVISA project has, therefore, improved the incomes of these groups, and we are seeing an increased demand for larger volumes of improved seeds within seed value chain actors and off-takers,” states the Tanzanian Program Coordinator, Papias Binagwa.

Both the Tanzania Official Seed Certification Institute (TOSCI) and the Tanzania Agricultural Research Institute (TARI) have been instrumental in supporting this initiative by providing training to farmers on current regulations and seed production practices. The QDS-producing farmer groups have been hosting local smallholder farmers for informational visits and field demonstrations to showcase the use of improved varieties and agronomic practices that enhance yields. As a result, QDS-producing farmers are full of praise.

“Thanks to this initiative, I have more sources of income as my yields have significantly increased from the seeds I sourced from TARI-Selian and ALSSEM seed company. The training has improved my seed handling and management. My extra agronomic knowledge will also benefit my fellow farmers,” says Baraka Hamis from Karatu district.

Joyce Yuda from the Chamwiilee Agro-Live QDS-producing group further stated, “Thanks to the seed sales, I have paid my children’s school fees and renovated my house. My food is assured, and I have economic freedom.”
