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.

Fidelia González 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.

Double the Harvest, Double the Income: Intercropping for Yield, Income and Security

Written by dmedina on . Posted in Blogs.

In the quiet villages of eastern India, a transformation is unfolding—led by smallholder farmers and powered by the science of intercropping.

“I got a good price for the cabbages, and I’m hopeful maize will do just as well. Look at it—it’s healthy and thriving,” says Nirmala Devi with a proud smile. At 45, Nirmala tends her small farm in Butijhari village, Kishanganj, Bihar.

She is one of 20 women in her village redefining farming through knowledge-sharing, new skills, and small-scale entrepreneurship.

“For the past two rabi (winter) seasons, we’ve been practicing intercropping with maize, Nirmala says, gesturing toward her fields. “We not only sell what we grow – cabbage, garden pea, beans, spinach, etc – but also exchange it among ourselves, depending on what we need at home.”

This approach has brought more than just additional income. It’s improving household nutrition, providing animal fodder, and increasing land productivity by growing two crops in the same plot during the rabi season.

Growing Together

Not only in villages of Kishanganj, into the villages of Coochbehar and Malda in West Bengal, farmers are seeing similar results. Now in their second year with the CIMMYT-led intercropping project, they are seeing substantial benefits—improved yields, additional income, and greater resilience against climate and or the failure of any single crop.

While intercropping isn’t new, this approach is different. CIMMYT and its partners, supported by the Australian Centre for International Agricultural Research (ACIAR), are promoting additive intercropping in wide-row staple crops like maize across India, Bangladesh and Bhutan.

Swaraj Dutta from Dr. Kalam Agriculture College under Bihar Agriculture University, working on the project, explains how this works: “We help farmers adjust the way they plant maize—either 60-60 cm spacing in single rows or a paired-row system at 30-90 cm. Between these rows, short-duration vegetables like cabbage, spinach, or legumes thrive early in the season.”

Maize and More

“The intensive cultivation of rice and maize (and previously wheat) is placing significant stress on natural resources and is becoming increasingly unsustainable in the face of growing climate change challenges. Yet, many farmers continue with these practices, even as returns diminish, due to a fear of diversifying,” explains Biplab Mitra of Uttar Banga Krishi Viswavidyalaya (UBKV), the university is supporting the intercropping project in Coochbehar and Malda districts of West Bengal.

“Traditionally, maize has been grown densely and often as a monocrop following rice in these regions. However, maize’s adaptability to both kharif and rabi seasons presents an opportunity to shift away from this unsustainable pattern”, added Mitra.  Through intercropping maize with vegetables during the rabi season farmers are now exploring more diversified and resilient farming systems that reduce pressure on resources and improve income potential.

“We used to grow only maize after rice,” says Santos Deb from Dinhata village, Coochbehar, standing proudly beside his wife Sochirani Deb. “But now, following the advice of scientists from UBKV, we intercrop. Two different crops, one cereal and one vegetable from the same field in the same season—that’s something we never attempted.”

On just 800 square meters, Barman adopted paired-row planting and added vegetables between maize rows. After covering input costs, he earned an additional ₹15,000–17,000 (US$180–200) for the vegetables, gained fresh food for the family, and produced fodder for their livestock. “This has been very rewarding for us. I have started growing in all my plots now,” he beams. “We’ll keep intercropping every rabi season throughout our lives.”

Intercropping offers a crucial buffer against climate-related risks by providing farmers a valuable source of additional income during the rabi season. Adverse weather events such as high winds, untimely late-season rains or storms often cause maize to lodge, resulting in significant yield losses and reduced income. By adopting intercropping, farmers can cover production costs earlier in the season and minimize exposure to climate-related economic losses.

Some farmers, like Kamal Ganesh from Chapati village in Kishanganj, see intercropping as a form of security against unpredictable harvests. “I grew cabbage and cauliflower under the project. Due to unavoidable circumstances, I was delayed in applying fertilizer and irrigating my maize crop, so the maize yield may be poor this harvest. But I’ve already earned a profit from the vegetables. Having a second crop in the same field acts as a safety net—if one fails, the other can still bring returns,” he explains.

Looking Ahead

Researchers assert that the project’s introduction of vegetable intercropping with maize offers new opportunities for diversification and resilience in the agriculture sector already stressed by climate change.

For many farmers, this is just the beginning. Alison Laing, leading the intercropping project at CIMMYT, shares her optimism: “This is only our second harvest across India, Bangladesh, and Bhutan, and already we’re seeing encouraging results. More and more farmers want to try it next season.”

Laing noted that further adjustments, including crop selection based on management needs, market value, and nutritional benefits, as well as efficient fertilizer use and market linkages, are being explored by researchers to enhance sustainability and broader adoption. “Apart from maize, we’ve also introduced intercropping in sugarcane fields in Meerut, Uttar Pradesh, in collaboration with the Indian Institute for Farming Systems Research (ICAR-IIFSR). We will review and analyse the results from the past two years in both maize and sugarcane practices to better understand farmers’ needs and support wider adoption,” she added.

Wide Row, Additive INTERCROPPING Project, led by CIMMYT and funded by ACIAR, is a 5-year initiative (launched in 2023) bringing together research institutions and agriculture scientists from India, Bangladesh and Bhutan to help smallholder farmers boost yields, increase their resilience to climate change and improve nutrition.  

Seeds of Change: Transforming agriculture in Koraput, Odisha

Written by dmedina on . Posted in Features.

Nestled amidst the enchanting Eastern Ghats in southern Odisha lies Koraput district, where agriculture is more than just a livelihood — it is a vital part of cultural identity. For Ranti Golari, a 58-year-old farmer from Jantaput village, this bond with the land runs deep. Yet, like many women farmers in her community, she faces numerous challenges. As she explains, “Reaching the marketplace is time-consuming,” she says, “and often, I return home empty-handed because there are no seeds available.”

A Deep-Rooted Farming Heritage

Koraput’s agricultural heritage is as unique as its landscape. For centuries, tribal communities have cultivated this land using practices passed down through generations. Their traditional methods received global recognition in 2012 when the Food and Agriculture Organization (FAO) designated Koraput as a Globally Important Agricultural Heritage System. This accolade celebrates their sustainable practices, which preserve native biodiversity, ensure food security, and protect the environment.

Local farmers possess an intrinsic understanding of their land, knowing precisely which crops will thrive in each season and how to maintain soil health. However, behind this legacy lies a complex web of challenges that threaten the region’s agricultural sustainability.

Challenges Beneath the Surface

Although agriculture employs 44% of Odisha’s workforce, it contributes only 24% to the state’s economy, reflecting low productivity and incomes.

Land fragmentation is a critical issue — 93% of farmers own less than two hectares, with the average size shrinking to just 0.95 hectares. These scattered plots reduce bargaining power and limit access to quality inputs and advanced farming technologies. Koraput’s remote location exacerbates these problems, leaving farmers disconnected from market trends and newer farming practices.

Women farmers, who make up 57% of Odisha’s agricultural workforce, face additional barriers. Weekly markets, known as padwas, are often 10 kilometers away, requiring arduous travel through rugged terrain. Limited transport and safety concerns compound their struggles. The unreliable quality of seed, often untreated or mixed with inferior varieties, further undermines their efforts.

Economic constraints further compound the problem. High seed costs, limited credit access, and weak market bargaining power trap farmers in a cycle of low productivity and profitability. As Ranti poignantly puts it, “Sometimes, the harvest barely matches the seeds we sow. Five bags sown and five bags harvested — how can farming be beneficial?”

A Solution Through Smallholder Aggregation

The Transforming Agrifood Systems in South Asia (TAFSSA) initiative introduced the innovative Small Farmers Large Field (SFLF) model to address these challenges. This approach aggregates fragmented land holdings and promotes collaboration among smallholder farmers.

Potatoes, with their rapid growth and soil-building properties, proved to be an ideal crop for the region. Rich in nutrients and widely accepted in the local diet, potatoes offer consistent market demand and opportunities for value-added processing.

In Kharif 2023, 54 farmers participated in the SFLF pilot, which focused on four key pillars:

  1. Access to quality seed: Farmers received standardized potato seed tubers, rigorously graded and sorted for quality.
  2. Streamlined seed delivery: Seeds were distributed directly to villages, saving time and transportation costs, especially for women farmers.
  3. Knowledge enhancement: Workshops and trainings, conducted in partnership with the local NGO Pragati, empowered farmers with improved agricultural practices.
  4. Market integration: By linking farmers to Farmer Producer Organizations (FPOs), the initiative strengthened their collective bargaining power, enabling them to obtain better prices for quality produce.

Economic Opportunities and Impact

As the world’s second-largest producer of potatoes, India offers immense potential for the crop. The introduction of rainy season potato production in Koraput allows farmers to supply fresh produce when market demand peaks, ensuring higher profits.

The impact of the SFLF initiative goes beyond economic gains. Reduced input costs, increased yields, and diversified incomes have improved financial stability, allowing families to invest in education and healthcare. Socially, the program fosters community bonds and empowers farmers through collective action and resource sharing.

Looking Ahead

The success of the SFLF model underscores the importance of targeted interventions that address seed quality, market access, and knowledge gaps. For farmers like Ranti, these changes mean more than agricultural improvement — they represent hope for preserving their heritage while building a sustainable future.

Koraput’s journey illustrates that agricultural transformation thrives when economic progress aligns with cultural preservation. As these farmers innovate and adapt, their experiences offer valuable lessons for similar regions across India.

With Innovations, They Protect Maize Biodiversity

Written by dmedina on . Posted in Blogs.

Rural women in Quintana Roo have been guardians of maize for generations. Today, with sustainable innovations and the support of technicians like Esmeralda Andrade, they are strengthening their role in food security and biodiversity conservation.

For generations, native maize has been at the heart of food systems and cultural identity in the Mayan communities of Quintana Roo. The women of these communities, heirs to the legacy of Mesoamerican societies that shaped native maize, have long selected and conserved seeds, ensuring the continuity of the varieties best adapted to their environments. In their hands, maize is not just a crop—it is a legacy.

Today, however, this legacy faces growing threats. High production costs, competition with less diverse farming systems, and increasing pressure from climate change are putting the biodiversity of native maize at risk. In response to these challenges, the Food and Nutritional Security for Rural Communities in the State of Quintana Roo project—promoted by the state government and CIMMYT—is working to strengthen agricultural productivity, seed conservation, and the sustainability of maize-based systems. At the center of these efforts are women.

In Quintana Roo, 74% of agricultural production units use native or criollo maize seeds, making the state a stronghold of maize biodiversity. However, data from INEGI’s 2022 Agricultural Census also reveal that only 17.9% of these units are headed by women. Despite their traditional role in conserving seeds, managing storage, and selling in local markets, the gender gap in agriculture remains significant.

To help close this gap, the project has prioritized training for women farmers—equipping them with scientific knowledge and technical tools to improve crop productivity and market access. These initiatives provide spaces for women to exchange seeds, learn improved agronomic practices, and build stronger support networks. Community seed houses and native maize multiplication plots have been established to support these efforts.

Esmeralda Andrade, one of the project’s technicians, promotes the integration of traditional knowledge with scientific approaches. “Many of our producers grow native maize, and use the lunar calendar to guide planting and management activities. They’ve also adopted innovations like optimal planting arrangements, seed treatment, and agroecological pest management,” says Esmeralda, highlighting how innovation can strengthen tradition.

This blend of knowledge strengthens food security and reduces the vulnerability of communities to climate change. “One of the key changes we’ve seen is that farmers now have a more sustainable outlook. They understand the importance of soil conservation and the quality of their agricultural products,” she adds.

The project has also been a platform for breaking down gender barriers in agriculture. As a female technician, Esmeralda has faced the challenge of working in communities where agricultural decisions have traditionally been made by men. “In the area where I work, due to customs and traditions, it is mostly men who attend meetings and workshops, so it can be difficult to engage with them,” she explains. However, the support of community leaders has been key to building trust and fostering inclusion.

Thanks to these efforts, more and more women producers are increasingly participating in decisions related to agricultural production and family food security. “The impact of women technicians is clear. Rural women are participating more in production activities and financial education. This fosters teamwork in rural households, where women are now making decisions—not just helping in the fields,” says Esmeralda.

The Food and Nutritional Security for Rural Communities in the State of Quintana Roo project not only aims to improve productivity and market access—it is also planting a seed of change in the role of women in agriculture. By providing them with tools to strengthen their role as guardians of maize, it is also enhancing their economic autonomy, community participation, and capacity to shape the future of agriculture in the region.

“My message to other women interested in becoming technicians or leaders in the agri-food sector is: don’t forget your worth and your abilities. Believe in your value—and above all, know that you’re not alone. You are supported every step of the way. There’s still a long road ahead,” Esmeralda concludes.

With projects like this, the rural women of Quintana Roo are showing that the best way to ensure the future of maize is through training, organization, and empowerment. In their hands, the legacy of native maize will continue to flourish.

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.

Caring for the Earth to Secure the Future

“The conventional way we used to prepare the land involved heavy soil disturbance, and now we see that’s not necessary. We used pesticides that were, let’s say, not kind to the soil. Now, we are becoming increasingly mindful of the environment — and it turns out to be more profitable. Today, I wouldn’t dare use a pesticide or any polluting product that could harm people or the environment.”

Leopoldo is a farmer from Sinaloa participating in the Supporting Responsible Sourcing in Mexico project — a collaboration between Kellogg Company and CIMMYT. For him, ceasing the practice of burning crop residues and instead using them to cover and protect the soil from erosion signifies a shift in values and a better way of practicing agriculture — one that actively contributes to regenerating the Earth.

The agronomic innovations adopted by farmers involved in the project promote a more balanced relationship with nature, aiming to strengthen a responsible sourcing model that ensures equilibrium between the economic, social, and environmental needs of both current and future generations. This contributes to a more sustainable production and consumption model, capable of feeding a growing global population within planetary boundaries.

If current patterns of production and consumption persist, it is estimated that in less than 30 years we would require the resources of three Earths to meet global needs. The rising scarcity of water and the reduction in arable land—driven by urban expansion and soil degradation—are clear reminders that our planet’s natural resources are finite. These facts underline the urgent need to accelerate the adoption of sustainable practices in agrifood systems.

Within the observance of International Mother Earth Day, efforts like the Supporting Responsible Sourcing in Mexico project serve as a reminder of the importance of forging a new relationship with the planet. Above all, they emphasize recognizing the Earth and its ecosystems as the shared home of all humanity. Failing to care for this home could lead us into further crises — in health, socioeconomic stability, and food security — and agriculture offers powerful solutions to safeguard this common home.

Globally, the agriculture sector is responsible for 24% of greenhouse gas emissions — which contribute to climate change — and 70% of freshwater withdrawals from rivers, lakes, and aquifers. Additionally, for every 1°C increase in global temperature, cereal yields are estimated to decrease by about 5%. Therefore, a new model of sustainable production and consumption must aim for reduced environmental impact, while increasing productivity and delivering benefits for farmers.

The Conservation Agriculture practices promoted by the Kellogg-CIMMYT project are advancing these goals: in just three years of work in Sinaloa and Guanajuato, nearly 7,000 hectares have adopted sustainable agricultural practices, leading to a 36% increase in average maize productivity. In 2021 alone, more than 350 farmers were engaged across over 2,400 hectares, producing nearly 26,000 tons of yellow maize through sustainable intensification technologies.

Looking ahead, the initiative aims to impact around 20,000 hectares to produce close to 180,000 tons of maize with a reduced carbon footprint. Already, farmers have achieved reductions in fuel use for grain production and improved water-use efficiency in irrigation.

“We save on machinery, on fuel, on agrochemicals, and on fertilizers. Now we produce with higher quality and at a lower cost because we practice minimal tillage. They also teach us integrated pest management and even how to optimize fertilizer use,” says Leopoldo, highlighting a system that also eliminates crop burning, one of the leading causes of wildfires.

By providing farmers with the knowledge and tools they need to integrate sustainable production methods, we benefit not only the Earth — but all of humanity.

A transformative leap in effective subaward implementation: Inside the revitalized sorghum and millets breeding programs at ZARI

Written by dmedina on . Posted in Blogs.

In the heart of Africa’s farming landscape, the Zambia Agricultural Research Institute (ZARI) is setting a new standard for agricultural research and climate resilience, thanks to a critical subgrant from the Bill & Melinda Gates Foundation, facilitated by the Africa Dryland Crops Improvement Network (ADCIN).

Established in August 2023 and convened by CIMMYT’s Dryland Crops Program (DCP), ADCIN is a collaborative network uniting over 200 scientists from more than 17 countries across sub-Saharan Africa. Its mission is to create a dynamic and sustainable community to develop and deliver improved varieties of dryland crops in the region. By leveraging the collective expertise of its multidisciplinary members, ADCIN strives to accelerate the access of enhanced crop varieties to smallholder farmers.

Through this partnership, ZARI has modernized its facilities and practices, creating a model for agricultural innovation in Eastern and Southern Africa. These advancements reflect a powerful vision of enhancing the capacity of breeding programs, improving crop resilience, and boosting food security for communities across the continent.

The Challenges of Transformation

Historically, ZARI faced significant challenges that limited its potential. As Lloyd Mbulwe, Acting Chief Agriculture Research Officer at ZARI, recalls:

“We faced research-related hurdles, from outdated lab facilities and inefficient irrigation systems to limited digital infrastructure and insufficient seed storage.”

These issues hindered not only ZARI’s ability to innovate but also its capacity for collaboration with regional and international partners.

With limited resources, ZARI was unable to meet the demand for high-quality, consistent research and innovation. Data collection was often manual, errors were common, and collaboration was difficult. The lack of modern infrastructure restricted the scope of experiments and the institute’s ability to respond to critical regional issues such as climate change and food insecurity.

A New Era of Modernization and Strategic Partnerships

In partnership with ADCIN, ZARI has received targeted funding and technical support, enabling transformative upgrades across its infrastructure that are redefining its research capabilities.

“The upgrades have reshaped our research capabilities,” Mbulwe explains. “With new equipment, enhanced data management systems, and a suitable greenhouse, we’re conducting better plant breeding experiments that directly address the region’s target product profiles.”

In July 2023, CIMMYT’s Dryland Crops Program conducted breeding program assessments of ZARI’s Golden Valley location, where the national institute’s sorghum and millets breeding programs are being conducted. Mark Nas, CIMMYT’s Sorghum and Millets Breeder for Eastern and Southern Africa, describes ZARI’s program as, “a high-potential program composed of talented and dedicated researchers and technicians, but in need of significant infrastructure upgrades if they are to meaningfully contribute to the shared regional breeding pipelines.”

With a subaward granted to ZARI by the end of 2023, Mbulwe and his team quickly worked on implementing the suggested improvements from the program assessments. Key upgrades include a greenhouse facility for speed breeding and controlled drought research, allowing researchers to rapidly produce lines for regional trials, while evaluating regional materials for drought tolerance. Enhanced water storage and solar power installations now enable uninterrupted research, even during power outages, a frequent challenge in this region. Transitioning to Starlink internet has also strengthened ZARI’s capacity for regional and international collaboration, and real-time data delivery, bridging communication gaps and enabling seamless data sharing.

Boosting Capacity for Impact

The new facilities have transformed ZARI’s capacity for impactful research. Rapid generation advance techniques, where breeding populations are quickly advanced through successive selfing generations, allow ZARI researchers to conduct multiple plantings within a year—dramatically boosting progress in line development.

Additionally, the upgrades also enable off-season research through the ZAMGRO Project, which has expanded water storage capacity from 45 cubic meters to an impressive 3,600,000 cubic meters. With year-round breeding, farming and water management research are now possible, giving ZARI an edge in breeding programs.

Mbulwe shares how automated data collection systems and standardized procedures have further improved the precision and reproducibility of ZARI’s research. “Our teams are now equipped to produce high-quality data leading to actionable results,” he says. “These improvements ensure the quality of outcomes and make our processes more efficient.”

A Vision for the Future

Looking ahead, ZARI plans to scale its research impact by establishing a Center of Excellence for Climate-Smart Agriculture and establishing a biotechnology lab to advance genetic improvement. Expanding greenhouse and irrigation systems, as well as enhancing digital infrastructure for data management, are key priorities. ZARI also aims to strengthen public-private partnerships to bridge the gap between research and practical applications for farmers across Zambia and beyond.

Inspiration and Best Practices for Other NARES Institutions

ZARI’s success story serves as an inspirational blueprint for other National Agricultural Research and Extension Systems (NARES) institutions. Through strategic partnerships, targeted investments in infrastructure, and an emphasis on capacity building, ZARI has shown what is possible when organizations and their leaders commit to modernizing and adapting to the evolving challenges of agriculture.

From irrigation upgrades to energy-efficient, solar-powered facilities, ZARI’s best practices are setting the stage for similar projects in other regions. “We’ve demonstrated that modernization can make a profound difference in NARES breeding programs,” says Dr. Mbulwe. “It’s about leveraging every resource to upgrade our plant breeding capabilities to address the challenges that climate change and food security bring to our region.”

The Role of ADCIN in Agricultural Innovation

ADCIN has been instrumental in supporting this transformation. Through its technical assistance, funding, and strategic guidance, ADCIN has empowered ZARI and other NARES institutions to elevate research standards across Africa. By aligning investments with regional research priorities, ADCIN not only supports individual institutions but also strengthens agricultural networks on a continental scale. Harish Gandhi, Associate Director of CIMMYT’s Dryland Crops Program, states, “We are operating in a new and transformative model of working with our partners. We want our partners to be resourced to succeed.”

ADCIN’s efforts to enhance research capacity, foster collaboration, and improve governance have seen significant returns. “This partnership has made ZARI a stronger institution,” Mbulwe asserts. “Our research output, regional partnerships, and access to funding have all grown. ADCIN’s support reaffirms its commitment to advancing the excellence of regional breeding and other research in dryland crops across Africa.”

Take-Home Message

ZARI’s journey is a prime example of the power of strategic investment, collaboration, and a shared commitment to addressing climate and food security challenges by building the capacity of national programs through equitable subawards. As it continues to innovate, ZARI remains a symbol of progress for agricultural research across Sub-Saharan Africa. With support from ADCIN, ZARI’s advancements signal a brighter, more resilient future for African dryland crops agriculture—one rooted in science, collaboration, and the promise of food security for all.

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 m². 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.
