The world needs better management of water, soil, nutrients, and biodiversity in crop, livestock, and fisheries systems, coupled with higher-order landscape considerations as well as circular economy and agroecological approaches.
CIMMYT and CGIAR use modern digital tools to bring together state-of-the-art Earth system observation and big data analysis to inform co-design of global solutions and national policies.
Our maize and wheat genebanks preserve the legacy of biodiversity, while breeders and researchers look at ways to reduce the environmental footprint of agriculture.
Ultimately, our work helps stay within planetary boundaries and limit water use, nutrient use, pollution, undesirable land use change, and biodiversity loss.

Functional diversification in agriculture seeks to maximize the potential of crops not only as sources of food but also as contributors to soil health, ecosystem stability, and economic sustainability. Through strategic design, agroecosystems can be strengthened to become more resilient, efficient, and productive. Mariel Guera, National Research Coordinator of the Sustainable Agrifood Systems (SAS) Program at CIMMYT, shares key recommendations for those interested in transitioning toward more diverse and functional systems.

Combining crops through practices such as maize–bean intercropping or maize–sesame relay planting enables more efficient use of system resources without reducing yields. These practices improve profitability, contribute to pest control, and promote efficient land use throughout the cropping cycle.
Assess before diversifying

Functional crop diversity reduces chemical inputs, improves soil health, and contributes to restoring ecological balance in the system. In the medium and long term, these benefits promote more efficient, regenerative production.
Intentional and knowledgeable diversification is key to achieving more resilient, productive, and sustainable agricultural systems. Incorporating functional crops that are adapted to local conditions and linked to clear objectives strengthens productive autonomy, improves profitability, and promotes more balanced agroecosystem management. For diversification to be effective, it is essential to assess the system, select appropriate species, and receive technical support.

CIMMYT played a key role in advancing research on yellow rust resistance by supporting field trials in Mexico and providing access to its extensive collection of traditional wheat varieties. Through its collaboration with the University of Zurich and Kyoto University, CIMMYT contributed to the identification of novel genetic regions in Asian landraces that offer resistance to the destructive fungus. Its leadership in conserving one of the world’s largest wheat germplasm collections continues to be vital for global efforts to develop disease-resilient wheat and safeguard food security through biodiversity.
In the May 2025 webinar co-hosted by CA4SH and the Vision for Adapted Crops and Soils (VACS), CIMMYT played a leading role through its co-leadership of VACS, promoting resilient food systems grounded in healthy soils and climate-adapted crops. Represented by Daniela Vega (CGIAR/CIMMYT), the Center highlighted VACS’ rapid growth and its efforts to bridge science, policy, and practice—supporting integrated soil health solutions, evidence-based decision-making, and advancing global commitments like the Soil Health Resolution.

Velu is in very distinguished company with his Derek Tribe award, with other CIMMYT awardees including Sanjaya Rajaram, who received the inaugural award in 2001 and was also the recipient of the world food prize in 2014, Ram Kanwar Malik (2015) and Ismail Çakmak (2007). Details about previous recipients of the Crawford Fund Derek Tribe Award are available here.
“Velu has an outstanding record of applying cutting-edge research to enhance agricultural productivity and natural resource management in developing countries. Over the past 15 years, his research at CIMMYT, Mexico, has played a pivotal role in breeding high-yielding, climate-resilient, and biofortified wheat varieties, addressing food security and malnutrition challenges across South Asia and Africa,” said Shaun Coffey, Chief Executive Officer, the Crawford Fund.
“Velu’s research has had significant impact, leading to the release of over 25 improved wheat varieties, benefitting millions of smallholder farmers in India, Pakistan, Nepal, Bangladesh, Ethiopia, and Mexico,” he said.
“Dr Govindan has been instrumental in integrating genomic selection, high-throughput phenotyping, and precision breeding techniques to accelerate genetic gains in wheat and zinc mainstreaming efforts at CIMMYT. His collaborations with national agricultural research systems (NARS) in developing countries have strengthened local breeding programs, enabling faster varietal development and dissemination,” said Shaun.
Velu’s work has received significant funding from international agencies such as the Bill & Melinda Gates Foundation, USAID, and other national and international funding, further demonstrating its global impact.
“Beyond breeding, Dr Govindan has contributed to sustainable agricultural practices by promoting climate-smart wheat varieties that require fewer inputs and are resilient to heat, drought, and resistant to multiple wheat diseases,” he said.
Prior to his role at CIMMYT, Velu was involved in pearl millet biofortification at ICRISAT through the HarvestPlus program, leading to the development of high-iron pearl millet hybrids adopted by smallholder farmers in India.
“He is also an advocate for capacity building, training young scientists and breeders across Asia and Africa; fostering the next generation of agricultural researchers; and actively participating in policy discussions that have influenced large-scale adoption of improved wheat varieties,” said Shaun.
“The Crawford Fund congratulates Dr Govindan on his lasting impact on global food security and natural resource management. We look forward to highlighting his work with the Derek Tribe address, and further raising awareness of the benefits to Australia and developing countries of agricultural research for food and nutrition security,” concluded Shaun.

Plans are underway for him to be presented with his award and deliver the 2025 Derek Tribe Address in the coming months. Information regarding the 2025 Derek Tribe Address will be shared when Dr Govindan’s trip is finalised.
In the lands of Oaxaca’s Mixteca, where rainfall no longer comes as it once did and the soil begins to feel the weight of years and intensive use, a network of women producers has taken on the task of healing the land—while also healing themselves. One of these women is Yuridia Hernández, who has decided to farm differently: with more awareness, less haste, and the support of other women who, like her, believe that a different kind of farming is possible.
Since 2023, Yuridia has been part of the Secure Maize Supply Program of the Secretariat of Food Promotion and Rural Development (SEFADER), supported technically by engineer Griselda Cruz Guzmán. On her three-hectare plot, she has begun applying agroecological practices: minimum tillage, biological pest management, the use of bio-inputs, and the reincorporation of crop residues. “We’ve gone back to practices we were already forgetting. Now we see our plants are more resilient. That motivates us to keep going,” she explains.

Last year, she planted late, like many in the region, due to delayed rains. But she didn’t give up. “This is a rainfed plot, and although the weather isn’t the same anymore, we can still produce if we change how we do it,” she says firmly. Though she works alongside her husband and eldest son in a family production unit, Yuridia makes her own decisions for her plot. “At first it was difficult—he (her husband) prefers mechanized methods, using chemicals. I would tell him: ‘wait, let’s try other options.’ And though it was hard for him to give up plowing, now he sees the results. Little by little, he’s adopted new practices.”
Like the Earth that gives life and regenerates when treated well, Yuridia has found a shared strength in other women. “In the group, you can feel when there are more women,” she says. “The men often come in with a different mindset, they find it harder to work as a team. But among women, it’s different: it’s enough to say, ‘how should we do this?’ and we organize ourselves.” She has especially formed close ties with another producer’s daughter, with whom she shares not just the work, but also a critical and forward-looking view of farming’s future: “We have that urge to do things differently, to improve them. And that’s made us a solid team. We pull each other forward—and also bring along the men who want to join.”
What began as an individual effort has now become a small network of learning, experimentation, and mutual support. By sharing knowledge, organizing field visits, and discussing what works and what doesn’t, Yuridia and her peers have been able to strengthen themselves and those around them: “That’s how we’ve grown stronger—by building a network.”
Beyond her own experience, she’s attended events at research platforms like those of INIFAP and CIMMYT, where she saw firsthand that sustainable practices can be applied in her context. “That’s where I said: this works, I want to replicate this,” she shares.
Yuridia also knows that climate change is not a distant issue. “It’s hit us hard. Rains aren’t like before, pests show up suddenly. But with these practices, the system is adapting. Where we leave more residues, the plants stay vigorous.” That’s why she doesn’t hesitate to send a message to those who support research and technical assistance: “Thank you for promoting these activities. Research really does help us. It lets us change or bring back what we already knew. If we do nothing, we’ll lose our land. But if we have tools, if we see examples, we can move forward,” she says gratefully.
Yuridia’s testimony reminds us that caring for the planet is not an abstract task—it starts in plots like hers, in voices like hers, in hands that sow with hope, science, and community. And just like the Earth, the women who care for and work the land have an immense capacity to regenerate, sustain, and transform.
In Zimbabwe, farmers are turning to conservation agriculture and climate-resilient crops such as millet, sorghum and cowpeas in order to combat the growing threat of drought, which has been exacerbated by El Niño. Traditional farming methods have left soils degraded and yields diminished, prompting many farmers, such as Memory Mukototse from Kaidza village, to adopt new techniques through programmes like the R4 Rural Resilience Initiative, which is led by the World Food Programme.
By comparing conservation and conventional farming methods, farmers have discovered that practices such as minimal soil disturbance, crop rotation and maintaining ground cover can greatly enhance harvests and improve water retention. Backed by CIMMYT, this farmer-driven research and peer-to-peer knowledge exchange, facilitated through seed fairs, group coordination and exchange visits, has not only enhanced food security, but also empowered communities to adapt and flourish in the face of challenging climatic conditions.

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.
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.
In a world where environmental and agrifood challenges demand urgent responses, the CGIAR-led Positive Solutions for Nature (Nature+) initiative is transforming agriculture into a catalyst for ecological regeneration and sustainable development.
In Colombia, CIMMYT has played a key role in implementing several activities under this initiative. These efforts have not only improved agricultural productivity but also promoted biodiversity conservation, sustainable resource management, and the strengthening of rural communities—with a special focus on youth, women, and native maize.
One of the first steps in Colombia was conducting a diagnosis and mapping key actors within agrifood systems across different regions. This assessment identified major challenges such as limited access to native seeds, soil degradation, and lack of access to fair market opportunities for smallholder farmers.
To ensure that promoted practices aligned with local realities and needs, CIMMYT worked closely with farmers to co-create solutions. A significant example was the support given to women producers to conserve native maize varieties. Workshops held in Cesar, Nariño, Putumayo, and Valle del Cauca included childcare spaces, enabling full participation by women.
Another important milestone was facilitating dialogue between producers and niche markets, helping connect farmers growing native maize with potential buyers. This has been key to revitalizing the value chain for these crops. In parallel, twelve community seed banks were strengthened in various regions, ensuring the availability of native varieties and encouraging intergenerational knowledge exchange.
CIMMYT also conducted extensive training activities, benefiting hundreds of farmers in the post-harvest management of native grains and seeds. In workshops held during 2023 and 2024, over 780 producers—many of them women—received training in practices such as harvesting, drying, shelling, and hermetic storage, which reduced post-harvest losses and improved seed quality.
Infrastructure improvements further supported these efforts. One standout example is the YEL-PUE Cumbe seed bank in Cumbal, Nariño—established with support from CIMMYT and the Bioversity-CIAT Alliance. This seed bank not only conserves agricultural biodiversity but also serves as an intergenerational learning hub, where farmers, students, and technicians share experiences and knowledge.
A key component of the initiative has been youth participation. Through collaboration with the José María Falla Educational Institution and youth networks like Herederos del Planeta, students have engaged in agroecological maize production. This involvement fosters stronger rural ties and ensures the continuity of traditional knowledge for future generations.
While challenges remain, the implementation of Positive Solutions for Nature in Colombia has demonstrated that agricultural production can go hand in hand with environmental conservation and community well-being. Thanks to collaborations with research centers such as CIMMYT, many Colombian farmers are now adopting regenerative practices, enhancing agrobiodiversity and boosting resilience to both climate and economic shocks.
Looking ahead, these efforts will continue within the CGIAR Multifunctional Landscapes Science Program. CIMMYT, in collaboration with other CGIAR centers, will focus on participatory varietal selection, business models to enhance the value of agrobiodiversity, connections to niche markets, and the empowerment of women as agents of biodiversity conservation.
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.
Munich Statement on Agriculture, Biodiversity and Security: there is no security without food security
The State of Mexico is supporting native corn preservation by providing MX$3.5 million in financial aid and equipment to local farmers. In collaboration with CIMMYT and UNAM, the government is advancing research to improve open-pollinated varieties and promote sustainable farming. As part of this effort, 833 seed accessions have been donated to enhance biodiversity and strengthen traditional maize cultivation. This initiative aims to support farmers while preserving Mexico’s rich maize heritage.
Somewhere in the enchanted valley of Santa Catarina Lachatao, Oaxaca, under the vast blue sky and in the heart of a land full of history and hope, Fabián Marcos Cano and Tomasa García Pérez are working toward the future they have long envisioned, their hands deep in the soil. In this land, where the Zapoteclanguage gives its name to the territory, each seed sown by their hands is an act of trust.
Fabián, his gaze marked by years of experience, speaks of his land with the pride of someone who has learned to listen to the voice of the earth. “We used to plant the way God guided us,” he says, recalling the days when farming was a practice of intuition and inherited wisdom.
Today, with the support of SEFADER technicians like Reinalda Gómez and her team, they have transformed their approach to farming. Fabián and Tomasa have learned to respect the rhythms of the soil, to give back what they take, and to see each plant through a new lens. “It’s like food for food,” Fabián explains.
Corn and beans grow unhurriedly in their fields. The land is enriched with crop residues that were once fed only to livestock, along with compost that was once discarded. “It’s a lot of work, but it’s our life,” says Fabián, with the firm determination of someone who understands that effort is part of the cycle.
For Tomasa, each harvest is a link to her ancestors. “The land gives us life,” she says with unwavering certainty. In her fields, milpa thrives alongside squash, beans, amaranth, and purslane, in a balance that requires patience and respect. She has learned to let nature do its work, to understand that burning fields robs the soil of its ability to renew itself. “We pile up the weeds, let them decompose, and that’s how the land nourishes itself,” she explains.
The journey has not been easy. Last year, a violent storm destroyed much of their crop. “It grew beautifully, but the wind tore everything down,” Fabián recalls with resignation. But they are not giving up. “We make do with what God gives us, because it is more than enough for us.” What remains is harvested as seed for the next cycle.
Every application of bio-inputs, every crop diversification, every lesson shared by agricultural engineers has changed their way of farming and their understanding of life. The land, once seen as an adversary that imposed its own rules, is now an ally that responds generously to care.
The story of Fabián and Tomasa is a testament to resilience and learning. It is proof that agriculture can be different, that tradition and innovation can go hand in hand. Because in every bean they harvest, in every ear of corn they save for the next cycle, there is a valuable lesson: the land gives back what it receives. And in Santa Catarina, under the sun that shines on Fabián and Tomasa’s fields, life flourishes with strength.
From 11 -22 November 2024, global leaders convened in Baku, Azerbaijan for COP29. Dubbed the finance COP, critical intersections of climate change, food systems, and sustainable development took center stage. This year’s conference reflected both the progress and the persistent challenges in addressing the climate crisis, marking a critical moment in the climate negotiations.
Food Systems at the Forefront
COP29 highlighted the undeniable importance of transforming global food systems as a cornerstone of effective climate action. Initiatives like the Harmoniya platform and the Declaration on Methane from Organic Waste shows the global community’s recognition of agriculture as both a contributor to and a solution for greenhouse gas emissions. However, the broader discussions were a reminder of the gap between ambition and implementation, with financial commitments and concrete action plans often falling short.
While food systems gained visibility, the debates often revealed tensions, particularly on issues like global stocktake outcomes, financing, and the integration of mitigation and adaptation strategies. Despite these challenges, the coordination and cohesion within the food systems community were commendable, reflecting a collective resolve to carry the momentum forward.
COP 29 – Baku, Azerbaijan
Key Outcomes and Agreements
Climate Finance and the NCQG
A central focus of COP29 was the New Collective Quantified Goal on climate finance (NCQG). While the actual need for climate finance is estimated at $1.3 trillion annually, the outcomes of COP29 fell short, with only $300 billion explicitly committed to developing countries. The inclusion of voluntary contributions from non-traditional donors like China and the UAE added nuance but failed to resolve the broader financial gaps.
Mitigation Work Programme
Discussions on the Mitigation Work Programme highlighted fundamental disagreements over whether the program should prioritize specific actions linked to the global stocktake. While some nations sought prescriptive approaches, others emphasized the voluntary nature of nationally determined contributions (NDCs). These debates highlight the complexities of aligning global and national climate priorities.
Adaptation and Resilience
The global goal on adaptation progressed with the launch of the Baku Adaptation Roadmap, though challenges remain in refining and agreeing upon adaptation-related indicators. Meanwhile, the Sharm El Sheikh Joint Work on Agriculture and Food Security moved forward with plans for an online portal to share best practices and tools for climate action.

Sundhani Tharu, a 44-year-old farmer from Pattharbojhi, Madhuwan-1 in the Bardiya district, in the mid-west of Kathmandu, is a leading example of how sustainable agricultural practices not only enhance crop production but also contribute to human and environmental health. Her dedication to a balanced approach to farming, which includes crop-livestock integration and the principles of the 4Rs of nutrient stewardship, has had a significant impact on her farm and the wider community.
Sundhani lives in a joint family of 58 members, with farming as the primary source of income. On their 8.13 hectares of land, they grow staple crops like rice, maize, mustard, and lentils, while also raising 26 cows, 17 buffaloes, and 45 sheep. Through this integration of crop production and livestock, Sundhani has built a closed-loop farming system where farmyard manure (FYM) from the livestock nourishes the crops, and crop residues feed the animals, ensuring minimal waste and promoting a natural balance between animals, crops, and soil health.

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

Though Sundhani can hardly read or write, she is contributing to the “One Health” movement—a global initiative that connects the health of people, animals, and the environment through best management practices in agriculture. By integrating crops and livestock, using farmyard manure, and applying the 4Rs of nutrient stewardship, she promotes a sustainable, eco-friendly system that enhances food security, improves soil health, and protects natural resources.
Looking ahead, Sundhani is determined to expand her farming ventures. She plans to venture into seed production for rice and mustard and hopes to increase her earnings from NPR 5 lakh (USD 3,740) to NPR 8 lakh (USD 5,987). By continuing to inspire her community and advocate for local vegetable markets, Sundhani envisions a future where farming is not only a source of livelihood but a cornerstone for a healthy, thriving ecosystem.
Sundhani Tharu’s story highlights the power of nutrient stewardship and sustainable farming to create healthier soils, crops, and communities. Through her dedication to the 4Rs, ISFM, and promoting farmyard manure use, she is paving the way for a future where agriculture is in harmony with nature—benefiting both people and the planet.
Participants of the seed systems and market intelligence team at the retreat in Kenya (Photo: CIMMYT).
The Seed Systems and Market Intelligence Team of the Sustainable Agrifood Systems (SAS) Program convened for a three-day retreat in Kenya. The retreat provided an opportunity to review ongoing research on seed systems and market intelligence conducted across CIMMYT projcts and CGIAR initiatives.
The event featured oral and poster presentations highlighting key findings from current research activities, fostering constructive feedback from colleagues. Discussion focused on strengthening the team’s technical capacity and ensuring its responsiveness to CIMMYT’s research programs and the broader CGIAR science agenda.
During the retreat, team members presented research spanning a wide range of topics. One key area focused on understanding the demands of farmers, processors, and consumers, for future crop traits, with the aim of informing breeding systems programs to maximize their impact.
The team highlight challenges faced by agro-processors, such as rancidity in pearl millet, which affects the shelf life of processed millet flour. Research also explored groundnut processing across different countries, revealing varied market demands.
In Malawi, groundnut markets prioritize grain size, color and uniformity-driven largely by export requirements-while oil content is less of a focus. In contrast, Nigerian markets demand high oil content for kuli kuli production and show a preference for early maturing varieties. Meanwhile, in Tanzania, an emerging peanut butter market has created opportunities for new groundnut varieties tailored to this product.
Seed systems research in Kenya highlighted how information and economic incentives for farmers and agro-dealers can serve as effective policy options to boost the adoption of new maize hybrids. These strategies have the potential to increase the market share of newly introduced hybrids in the maize seed sector.
The team showcased the impact of providing variety-specific, independently evaluated yield data for commercially available seed products under local conditions to guide farmers’ seed choices. Additionally, they explored the use of rebates as incentives for agro-dealers to stock new products and actively encourage farmers to try them. The role of price discounts and targeted information at the retail level for newly released varieties was also discussed as a way to promote adoption among farmers.
Another key area of research focused on how farmers perceive existing promotional materials distributed by seed companies. Feedback indicated that most leaflets and posters were not visually engaging. Farmers expressed a preference for materials that include visuals of plant stands, cob sizes, yield potential, and other critical details, presented in local languages like swahili.
Looking ahead, the team outlined a new four-year project supported by the Impact Assessment Group under the Genetic Innovations Action Area. This initiative will build on the current findings to generate further evidence on how information can accelerate farmer adoption of new seed products. It will also examine the role of agro-dealers as key information agents to disseminate knowledge effectively to farmers.
The meeting also highlighted the assessment of varietal turnover in Ethiopia and the role of the DNA Fingerprinting (DNA FP) approach in improving the accuracy of varietal identification. Accurate data generated through this method supports more robust studies on varietal adoption, turnover, and impact. It also enables the assessment of whether released varieties are being cultivated within their target agro-ecologies and contributes to understanding varietal diversity within production systems.
Discussions emphasized the relevance of the DNA FP approach for accurate data collection and its potential for broader application beyond Ethiopia, Tanzania, and Nigeria, where the IMAGE project is currently active. Expanding its use to other regions would further strengthen research efforts in seed systems and market intelligence.
Paswel Marenya, associate program director of SAS Africa, commended the team for the depth and breadth of their research and encouraged greater visibility of results within CIMMYT and beyond. As a key outcome of the meeting, the team committed to increasing its visibility in seed systems and market intelligence research while building a stronger, more qualified team to achieve this goal.
In terms of staffing, the team has a solid presence in Africa but aims to expand its reach through enhanced resource mobilization. Efforts are underway to strengthen the Seed Systems and Market Intelligence team’s presence in other regions where CIMMYT operates, including Latin America (LATAM) and South Asia.
