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.

Every year, public and private sector partners participate at The International Maize Improvement Consortium for Africa (IMIC-Africa) Field Day for Southern Africa, a unique event that seeks to transform the maize sector. The 2025 field day, hosted at the University of Zimbabwe farm on April 9th, brought together an eclectic blend of partners from seven African countries, including long-standing collaborators and new entrants such as AMAC Seeds and Grow Trade Seeds. Moving beyond just showcasing key achievements and new germplasm to partners, the field day fostered critical and meaningful discussions and experience sharing among partners, from lab to farm.

By offering access to both early- and advanced-generation maize lines, the event was a critical intersection point where public and private players align to tackle the continent’s most pressing agricultural challenges. In addition, members have the opportunity to test their pre-commercial hybrids through CIMMYT-led multi-location trials, ensuring that the products are carefully evaluated across diverse agroecologies and for essential traits such as drought tolerance, pest resistance and high yield potential. It also provides an avenue for suggesting improvements to the demonstrations, ranging from labelling.

We took time to get a clear perspective from CIMMYT scientists, private and public sector representatives.

Q: How important is the IMIC-Africa Field day in addressing maize sector challenges?

“Success of breeding programs is hinged on injection of new genetics that drive gains. Developing high value inbred and donor lines is an expensive process and platforms such as IMIC Africa help reduce product development costs in maize breeding programs of the partners and reduce time taken to deliver solutions to farmers,” emphasized Aparna Das, Senior Technical Program Manager for the Global Maize Program.

“It is rare to get an opportunity to observe and select hundreds of lines in one location as it offers each participant an opportunity to see the performance potential of each line at a glance” said James Gethi, southern Africa Seed Systems Specialist and IMIC Africa southern Africa coordinator.

Mainassara Zaman-Allah, CIMMYT’s Country Representative for Zimbabwe, reflected on the core strengths of the consortium, “It has been 8 years since the launch of the initiative, and one of the core strengths of IMIC-Africa is its inclusivity. Whether from a national agricultural research institution, maize seed company or international agricultural research organizations, IMIC-Africa opens its doors for all involved in maize breeding for the African market. This diversity enables us to leverage a broad range of expertise and resources, to articulate the challenges faced by African farmers.”

Q: What impact have the maize lines had on breeding programs?

“We have seen major improvements in the vigor of materials displayed that open a new frontier for single cross hybrid varieties development” commented Oswell Ndoro from AMAC seeds, a new member of IMIC Africa, signalling optimism for the future.

Walter Trevisan, consultant for Helix Seeds, praised CIMMYT’s Zimbabwe scientists for their collaborative support in selections, “Thank you very much for this outstanding work! We sure appreciate the help of the CIMMYT Zimbabwe scientists in helping us with this task.”

Davison Chaingeni from ARISS, formerly DR&SS Zimbabwe, echoed this, “We continue to see value in getting more DH-based lines. We hope the vigor translates to yield.”

 

 

 

 

 

 

 

 

 

Q: Take us through on what was on offer in the field, where science meets need and demand.

“An array of 624 CIMMYT maize lines were on display, which consisted of 614 new lines from 4 different product profiles providing insights into the performance of different materials. The materials span early-, intermediate, and late- maturity groups to nutritious maize breeding pipelines. A critical component of the field display was trait donor lines where 5 lines were on display for selection. The traits donor lines on display were for drought, drought & heat and Low N & MLN tolerance. This comprehensive showcase enabled seed companies and NARS partners to make informed selections, tailored to their breeding needs,” Gethi explained.

Development of provitamin A-enriched maize (PVA) addresses one of the emerging challenges in combating hidden hunger and animal feed. He further adds, “On display were 126 lines originating from the PVA-enriched maize breeding pipeline. The efforts underscore CIMMYT’s commitment to address regional nutritional needs through targeted breeding initiatives.”

Q: What improvements would partners like to see moving forward?

Amsal Tarekegne, head of breeding at Zamseed Seed Company, pointed to a practical bottleneck, “It is a challenge understanding the pedigree information provided in the field book due to its length.”

 

 

 

 

 

 

 

 

 

 

Yet, the road ahead still demands refinement.  Lubasi Sinyinda from Zambia Agricultural Research Institute (ZARI), one of the NARS partners in IMIC-Africa since its inception, noted, “I would like to see more fall armyworm (FAW) and heat-tolerant lines displayed.”

For new entrants like Petros Guveya of Grow Trade Seed company, navigating CIMMYT’s updated heterotic groupings was a challenge, underlining the need for improved orientation for first-time participants.

On the brighter side, Themba Mutuvira complimented the design of the fields by indicating they were easy to navigate through. “The fields were well labelled, and we had no challenges at all identifying the materials”

A living laboratory for Africa’s Maize future

The 2025 IMIC-Africa Field Day was not just an event, but a living laboratory of innovation, critique, and partnership. In the face of mounting climate pressures, pest threats, and nutritional gaps, such platforms offer a rare and invaluable opportunity for the maize breeding community to align, adapt, and accelerate. As IMIC-Africa evolves, the call from partners is clear: deepen inclusivity, enhance clarity, and continually refine the experience to ensure that each plot, each line translates into impact on the farm and food on the table. The future of Africa’s maize sector will be built not in silos, but in such collaborative spaces where science meets the lived realities of farmers and seed companies alike.

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

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

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

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.

New Breakthrough in Wheat Blast Resistance: A Novel Non-2NS QTL Identified

A newly published study has identified a significant breakthrough in the ongoing battle against wheat blast: a novel quantitative trait locus (QTL), named Qwb.cim-7D, located on the long arm of chromosome 7D and derived from Aegilops tauschii, offers stable and moderate resistance to wheat blast—independently of the widely used 2NS translocation.

Wheat blast, caused by Magnaporthe oryzae pathotype Triticum (MoT), is a rapidly spreading disease threatening wheat production, particularly in tropical and subtropical regions of the world. First detected in Brazil in 1985, the disease has since caused devastating yield losses—up to 100% in severe cases. Its transboundary spread, including recent incursions in Bangladesh and Zambia, has intensified international concerns about food security, especially among vulnerable smallholder farming communities. Control through chemical means has proven unreliable, placing even greater emphasis on the development and deployment of resistant wheat cultivars.

For years, wheat breeders have relied on a single major source of genetic resistance—the 2NS/2AS translocation from Aegilops ventricosa. While initially effective, recent field observations—particularly in Brazil—suggest that wheat blast pathogens are evolving to overcome this resistance. Despite extensive efforts, previous studies have failed to identify any non-2NS QTLs with both significant and stable effects across environments in field trials.

A New Genetic Solution for Blast Resistance

In a recently published study entitled “A novel QTL on chromosome 7D derived from Aegilops tauschii confers moderate field resistance to wheat blast”, CIMMYT’s wheat pathology team and collaborators reported the identification of a novel and consistent QTL—Qwb.cim-7D—which provides significant resistance to wheat blast independent of the 2NS translocation.

The donor bread wheat line, Gladius*2/KU 2097, inherited its resistance from the resistant Ae. tauschii accession ‘KU-2097’. Field experiments were conducted at two Precision Phenotyping Platforms (PPP) in Bolivia (Quirusillas and Okinawa) and one PPP in Bangladesh (Jashore), under artificially inoculated conditions—ensuring a robust evaluation of resistance. The QTL was mapped to the long arm of chromosome 7D, where it explained between 7.7% and 50.6% of the phenotypic variation across different environments. This is a significant finding, as previous studies identified non-2NS resistance loci with typically small effects (less than 10%) and inconsistent performance. In contrast, Qwb.cim-7D is the first moderate-effect QTL to demonstrate stable resistance across multiple field conditions.

To facilitate its adoption in breeding pipelines, researchers successfully converted the flanking DArTseq markers into KASP markers—enabling more efficient marker-assisted selection.

Importantly, Qwb.cim-7D provides approximately half the resistance effect of 2NS, highlighting its value as a complementary resistance factor. When deployed through gene pyramiding strategies alongside 2NS and Rmg8, this new QTL could help breeders develop varieties with stronger and more durable resistance to the evolving wheat blast pathogen.

This breakthrough marks a turning point in global wheat blast resistance breeding. It addresses the urgent need to diversify the genetic basis of resistance and equips breeders with a viable new tool to safeguard wheat yields. As wheat blast continues to threaten food security in key regions, the introgression of Qwb.cim-7D into breeding programs offers a promising path toward enhanced crop resilience and improved farmer protection.

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

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

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

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

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.

Rising from adversity: The inspiring success of Asma and Tasin’s engineering workshop

Asma Akter and her daughter, Tasin Fahariya, have emerged as inspiring examples of resilient agriculture-based light engineering (ABLE) entrepreneurs in Bangladesh. Their journey began in the face of tragedy when Asma, at 38, lost her husband to COVID-19. As the proprietor of Belal Engineering Workshop, a family business started by her late husband 32 years ago, Asma took on the responsibility of running the manufacturing enterprise.

The initial challenges were daunting. Customers lost trust in the company’s ability to deliver quality products on time under the leadership of a woman. Even their experienced workshop staff felt insecure about their job prospects under the new management. Financial institutions were hesitant to provide loans to a woman-led business, making it difficult to purchase raw materials for production.

However, their fortunes changed with the connections they made. Tasin received training in Financial Management, Digital Marketing, and Technical Drawing and Design. These courses enhanced her professional skills and boosted her confidence to lead the business effectively. They secured a loan of over US$4,300 from Gram Unnayan Kendra (GUK), addressing their capital needs.

They connected with dealers across Bangladesh, significantly expanding their customer base. They branded their products through smart packaging and organizational branding with logos, which helped them compete more effectively in the market.

As a result of these interventions, Asma and Tasin’s business has seen remarkable growth. They’ve expanded from 10 dealer points to 14, adding new geographical regions to their network. Their order volume and sales have increased tremendously. The mother-daughter duo’s achievements go beyond financial gains—their success underscores the importance of diverse viewpoints in enhancing and optimizing manufacturing processes.
