Catalyzing smallholder farming in Mexico
Scientists from CIMMYT, founded in Mexico in 1966, have pursued decades of participatory research with Mexicoâs smallholder maize farmers to improve their local varieties for traits like yield and insect resistance, while preserving their special grain quality, as well as testing and promoting zero-tillage and other resource-conserving farming practices.
Smallholder farm operations account for more than 80% of all farms worldwide and produce roughly 35% of the worldâs food, according to FAO census data and follow-up studies.
An estimated two-thirds of the Mexicoâs farmers are smallholders, typically working challenging agroecologies scattered across the countryâs mountainous terrain and applying generations-old subsistence practices to grow low-yielding local maize varieties.
Ancient milpa multicropping systems can lift up the present and future
The milpa intercrop â in which maize is grown together with beans, squash, or other vegetable crops â has a millennial history in the Americas and can furnish a vital supply of food and nutrients for marginalized, resource-poor communities.
One hectare of a milpa comprising maize, common beans, and potatoes can provide the annual carbohydrate needs of more than 13 adults, enough protein for nearly 10 adults, and adequate supplies of many vitamins and minerals, according to a CIMMYT-led study in the western highlands of Guatemala, an isolated and impoverished region, reported in Nature Scientific Reports in 2021.
But milpas are typically grown on much smaller areas than a hectare, so households cannot depend on this intercrop alone to satisfy their needs. A solution? Customized milpas that merge farmersâ age-old wisdom and practices with science-based innovation.
An example is planting fruit trees â guava, avocado, mango, peaches, or lime among others â among milpa crops in lines perpendicular to hill slopes. The practice was tested and promoted in the Los Tuxtlas region of the state of Veracruz by Mexicoâs National Institute of Forestry, Agriculture, and Livestock Research (INIFAP) and the Colegio de Postgraduados (ColPos) and has been refined by farmers in other areas through CIMMYT-led innovation networks.
In Los Tuxtlas the practice provided added income and nutrition, dramatically reduced erosion, improved land and water-use efficiency by around 50%, and boosted soil health and fertility.
In the state of Puebla and other parts of South and southwestern Mexico, milpa-fruit tree intercrops have worked well on steep hillsides. In the state of Oaxaca, for example, versions of the practice have notably improved farming by indigenous communities in the Mixe and Mazateca regions, supported by outreach of the Mexican Agency for the Sustainable Development of Hillsides (AMDSL), a partner in a CIMMYT research hub in the region.
Research by AMDSL and CIMMYT on smallholder plots in two Oaxaca municipalities where farmers have been combining milpas with peach and avocado production and conservation agriculture practices for more than a decade found that cropping diversification, together with use of zero tillage and keeping crop residues on the soil rather than removing or burning them, raised total yearly crop outputs by as much as 1.7 tons per hectare and reduced farmersâ risk of catastrophic crop losses due to droughts or other climate extremes.
Blue maize pleases diners and delivers profits
Farmersâ local maize varieties yield less than hybrids but are still grown because they provide ideal grain quality for traditional foods, as well as marketable stalks and leaves to feed farm animals and maize husks for wrapping tamales, to name a few products.
Building on longstanding partnerships with INIFAP and the Autonomous University of Chapingo (UACh) to improve local varieties and preserve maize genetic diversity in Mexico, CIMMYT breeders have recently developed improved blue maize hybrids and open-pollinated varieties.
Sought by restauranteurs worldwide for its flavor and beauty, blue maize grain normally comes from native varieties grown by smallholder farmers on small plots with low yields and variable quality.
The new CIMMYT varieties are derived from traditional Guatemalan, Mexican, and Peruvian landraces and feature higher yields, more consistent grain quality, and enhanced resistance to common maize diseases, offering smallholders and other Mexican farmers a profitable product for the countryâs booming restaurant industry and for export chains.
Parental inbred lines of the new hybrids have been distributed to private and public partners, who are developing their own hybrids and OPVs in Mexico. CIMMYT continues to test the new hybrids under various farming systems to ensure they produce stable yields when grown in farmersâ fields.
Data driven extension
Using cutting-edge data systems, CIMMYT has leveraged information from nearly 200,000 plots representing more than 26,000 hectares across diverse agroecologies to offer Mexican farmers â including smallholders â site-specific recommendations that make their farming systems more productive, resilient, and sustainable. The initiative was supported by MasAgro, an integrated development partnership of Mexico and CIMMYT during 2010-21 and funded by Mexicoâs Secretariat of Agriculture and Rural Development (SADER).

Women leaders in science: reaching out to break through
On August 15, 2023, CIMMYT organized the third series of the Catalysts of Change: Women Leaders in Science virtual seminar for a conversation on advancing womenâs leadership in science, showcasing a wealth of power-packed insights and success stories.
Featuring Catherine Bertini, an accomplished leader in international organization reform and a powerful advocate for women and girls, the TED talk meets fireside chat style seminar began with a pre-recorded message from Catherine highlighting how women as catalysts of change can play an essential role in breaking through gender barriers in leadership roles. âEach of us must define for ourselves what’s important to us. We should assume opportunities to lead and to improve. We need to reach out, look forward and say, I’m going to make a difference. We can all be a catalyst for change,â stated Catherine, the 2003 World Food Prize laureate.
CIMMYT Director General Bram Govaerts highlighted the importance of recognizing the immeasurable contributions of women leaders in science. âWe want more women leaders in organizations like CIMMYT. Through the recently launched CIMMYT 2030 Strategy, we are taking one step further in ensuring that gender equality isnât just a concept but a reality, he reiterated. “The CIMMYT 2030 Strategy leverages a systems approach to overcome barriers to achieving gender equity by providing more opportunities to hear and learn from current women leaders in all capacities,â explained Govaerts.
âGirls can do anything,â Catherine set the scene for her presentation, showcasing personal stories based on her remarkable career and leadership journey. She detailed her distinguished career of improving the efficiency and operations of organizations serving poor and hungry people around the world. Sharing behind-the-scenes insights and actionable takeaways, Catherine wanted participants to walk away remembering, âhere are some of the things that I have learned that I’d like to share with you today: engage in meaningful networking opportunities; be intentional about the impacts you want to create; understand your own tolerance level; be grounded in your principles, and champion inclusive leadership by mentoring others.â
Natalia Palacios, a member of the Woman in Science group at CIMMYT, interviewed Catherine. âCatherineâs contributions have been instrumental in enhancing food security, nutrition, and gender equality. Her advocacy has shed light on the crucial roles that women play in food production, family nutrition and community resilienceâareas that are aligned with CIMMYTâs mission,â said Natalia. Responding to Nataliaâs question on proud moments, Catherine talked about the Trust Fund she created with her World Food Prize to support programs that increased opportunities for girls and women to attend school. âI created the Catherine Bertini Trust Fund for Girlsâ Education. There are some wonderful stories of support we’ve given. I learned that nobody should underestimate their potential to be a role model,â she added.
Catherine also addressed questions from session participants on how to build inclusive organizations through a learning culture; tips to help employees adapt to new technology in the age of artificial intelligence (AI);Â and approaches to manage culture change: how to find the balance and address tensions and trade-offs.
The third session ended with closing remarks from Bram who expressed his gratitude to Catherine for participating in the Catalysts of Change Seminar Series, highlighting her incredible leadership journey and unwavering passion in accelerating the advancement of women in leadership. âThis was such an inspiring conversation. There are two take home messages for me: let us appreciate the contributions of those who came before us; and we need more dialogue and to listen to each other much more,â he concluded, underscoring CIMMYTâs commitment to changing the leadership equation through greater representation of women leaders at CIMMYT and CGIAR.

Smallholder Mexican farmers adopt resource-conserving innovations: slowly and in bits
Small-scale farmers in Mexico often adopt conservation agriculture innovations gradually and piecemeal, to fit their diverse agroecological and socioeconomic contexts and risk appetites, according to studies and the on-farm experience of CIMMYT.
Research and extension efforts need to consider this in work with smallholders, said Santiago Lopez-Ridaura, a CIMMYT specialist in agricultural systems and climate change adaptation.
“Farmer practices typically involve heavy tillage before seeding, growing maize as a monocrop, and removing crop residues after harvest for use as forage,â explained Lopez-Ridaura. âFull-on conservation agriculture (CA) is a radical shift, requiring farmers to reduce or eliminate tillage, keep a permanent cover of crop residues on the soil, and diversify the crops they grow. It can support more intense yet environmentally friendly farming, reducing erosion, improving soil fertility and water filtration, boosting crop yields, and saving farmers money. However, it also requires purchasing or contracting specialized sowing implements and fencing fields or agreeing with neighbors to keep livestock from eating all the residues, to name just a few changes.â
Lopez-Ridaura and colleagues published a 2021 analysis involving farmers who grew maize and sorghum and keep a few livestock on small landholdings (less than 4 hectares), with limited mechanization and irrigation, in the state of Guanajuato, Central Mexico.
They found that scenarios involving hybrid maize plus a legume crop with zero-tillage or keeping a residue mulch on the soil provided an average net profit of some US $1,600 (MXP 29,000) per year, in addition to ecological benefits, added forage, and more stable output under climate stress.
âUsing a modeling framework from Australiaâs Commonwealth Scientific and Industrial Research Organization (CSIRO) that combines bioeconomic simulation, risk analysis, adoption theory, and impact assessment, we not only confirmed the worth of conservation agriculture but found that disaggregating CA into smaller component packages and including a more productive crop and variety were likely to increase farmersâ adoption, in riskier settings.â
Advancing more sustainable farming in Mexico
Conservation agriculture can generate substantial economic and environmental benefits under marginal conditions, particularly by enhancing climate change resilience, increasing soil organic matter, and retaining soil moisture. In Central Mexico dryland maize yields rose by 38-48%, after 10 years of implementing CA.
CIMMYT has studied and promoted zero-tillage for maize and other resource-conserving practices in Mexico for more than three decades, but efforts to spread sustainable farming and use of improved maize and wheat varieties redoubled thanks to MasAgro, a research initiative led by the Center and supported by the government of Mexico during 2010-21. Testimonials such abound of Mexican smallholder farmers who have adopted and benefited from CA practices through CIMMYT and national partners’ efforts in MasAgro and other initiatives.
- Looking to lower his farm costs without losing output, wheat and oil crop farmer Alfonso Romo of Valle de Mayo, state of Sonora, began practicing CA in 2010. âWe’ve learned a lot and this year (2022) we obtained the same yields as we used to get through conventional practices but, following more sustainable farming methods, with a 30 and even 40% savings in fertilizer.”
- With CA practices he adopted in 2018 through MasAgro, maize farmer Rafael Jacobo of Salvatierra, state of Guanajuato, obtained a good crop despite the late dispersal of irrigation water. Seeing his success and that of other nearby farmers, neighbor Jorge Luis Rosillo began using CA techniques and has noticed yearly improvements in his soil and yields. “I did everything the technicians recommended: keeping the residues on the soil and renewing only the sowing line on soil bedsâŠ. There are lots of advantages but above all the (cost) savings in land preparation.”
- Farmers in the Milpa Sustentable project in the YucatĂĄn Peninsula have improved maize yields using locally adapted CA methods, in collaboration with the Autonomous University of YucatĂĄn. Former project participant Viridiana Sei said she particularly liked the respectful knowledge sharing between farmers and project technicians.
- CA practices have allowed more than 320 women farmers in the Mixteca Region of the state of Oaxaca to provide more and better forage for the farm animals they depend on, despite drought conditions, through the Crop and Livestock Conservation Agriculture (CLCA) project supported by the International Fund for Agricultural Development (IFAD). According to farmer MarĂa MartĂnez Cruz, “… it hasn’t rained much and everything’s dry, but our verdant oat crop is allowing us to keep our farm animals fed.”
- With CLCA support and facing Mexico’s increasingly fickle rainy season, farmer Mario GuzmĂĄn Manuel of San Francisco ChindĂșa village in Oaxaca began using CA and says he’ll never go back to the old practices. “We used to do as many as two harrow plowings to break up the soil, but if we leave the residues from the previous crop, they hold in the soil moisture more effectively. People hang onto the old ways, preferring to burn crop residues, but we should understand that this practice only deprives the soil of its capacity to produce.”
A Mexican farm research program gains praise and interest for use abroad
Leveraging the leadership, science, and partnerships of the Mexico-based CIMMYT and the funding and research capacity of Mexicoâs Secretariat of Agriculture and Rural Development (SADER) during 2010-21, the program known as âMasAgroâ has helped up to 500,000 participating farmers to adopt improved maize and wheat varieties and resource-conserving practices on more than 1 million hectares of farmland in 30 states of Mexico.
As a result of MasAgro research hubs operating across Mexicoâs multiple and diverse agroecologies to promote the sustainable intensification of maize and wheat farming systems â including improved varieties and resource-conserving, climate-smart practices â yields of project participants for maize were 20% higher and for wheat 3% higher than local averages. Similarly, average net incomes for participating maize farmers were 23% greater and 4% greater for wheat farmers, compared to local averages.
The MasAgro biodiversity component gathered and analyzed one of the worldâs largest-ever samplings of maize and wheat genetic diversity, including CIMMYTâs own vast seed bank collections, to help identify and characterize new genes of interest for breeding. As one result, more than 2 billion genetic data points and over 870,000 data entries from associated field trials are freely available to the scientific community, via the projectâs online repository.
MasAgro has involved national and local research organizations, universities, companies, and non-government organizations working through more than 40 research platforms and 1,000 demonstration modules, while building the capacity of thousands of farmers and hundreds of technical and extension experts who serve them.
State-level partners sign on to MasAgro
Through MasAgro, CIMMYT entered into research and development partnerships with 12 Mexican states. An example is the mountainous, central Mexican state of Guanajuato, home to the El BajĂo region, one of Mexicoâs most productive farm areas but which also suffers from soil degradation, water scarcity, and climate change effects â challenges faced by farmers throughout Mexico. The governor of Guanajuato visited CIMMYT headquarters in Mexico in June 2023 to review progress and agree on follow-up activities.
CIMMYT has worked with Guanajuato state and local experts and farmers themselves to test and promote innovations through 7 research platforms reaching nearly 150,000 hectares. As of 2020, new crop varieties and resource-conserving, climate-smart management practices had helped underpin increases of 14% in irrigated wheat production and, under rainfed farming systems, improved outputs of 28% for beans, 150% for local maize varieties and 190% for hybrid maize, over state averages.
An integral soil fertility initiative has included the analysis and mapping of more than 100,000 hectares of farmland, helping Guanajuato farmers to cut costs, use fertilizer more effectively, and reduce the burning of crop residues and associated air pollution.
Service centers for the rental and repair of conservation agriculture machinery are helping to spread practices such as zero tillage and residue mulches. Supported by CIMMYT advisors, Guanajuato farmers are entering into equitable and ecologically friendly production agreements with companies such as Nestle, Kelloggâs, and Heineken, among other profitable and responsible public-private arrangements.
Acclaim and interest abroad for MasAgro
MasAgro has received numerous awards and mentions as a model for sustainable agricultural development. A few examples:
- The Inter-American Development Bank (IDB) mentioned the program as an example of successful extension.
- The Organization for Economic Cooperation and Development (OECD) cited MasAgro for promoting productive and sustainable agriculture.
- The United Nations Development Program (UNDP) lauded MasAgro for promoting climate-resilient agriculture.
- During the 2018 G20 summit in Argentina, MasAgro was considered a model for coordinating agricultural research, development, innovation, technology transfer, and public-private partnerships.
- Bram Govaerts, now Director General of CIMMYT, received the 2014 Norman Borlaug Field Award for his work at the time as leader of MasAgroâs farmer outreach component.
- MasAgro research hubs were recently used as a guide by USAID for efforts in Sudan and Eastern Africa. They have also been replicated in Guatemala and Honduras.
Moving out and beyond
In Central America and Mexico, the inter-connected crises of weak agri-food systems, climate change, conflict, and migration have worsened, while small-scale farmers and marginalized sectors remain mired in poverty.
Capitalizing on its experience in MasAgro, CIMMYT is a major partner in the recently launched CGIAR initiative, AgriLAC Resiliente, which aims to build the resilience, sustainability, and competitiveness of agrifood systems and actors in Latin America and the Caribbean, helping them to meet urgent food security needs, mitigate climate hazards, stabilize vulnerable communities, and reduce forced migration. The effort will focus on farmers in Colombia, El Salvador, Honduras, Mexico, Nicaragua, and Peru.
As described in a 2021 science journal article, CIMMYT also helped create the integrated agri-food system initiative (IASI), a methodology that was developed and validated through case studies in Mexico and Colombia, and leverages situation analysis, model predictions, and scenarios to synchronize public and private action toward sustainable, equitable, and inclusive agri-food systems.
âCIMMYTâs integrated development approach to maize system transformation in Mexico and Colombia laid the foundations for the IASI methodology by overcoming government transitions, annual budget constraints, and win-or-lose rivalries between stakeholders, in favor of equity, profitability, resilience and sustainability,â said Govaerts.
The 2021 Global Agricultural Productivity (GAP) report âStrengthening the Climate for Sustainable Agricultural Growthâ endorsed IASI, saying it ââŠis designed to generate strategies, actions and quantitative, Sustainable-Development-Goals-aligned targets that have a significant likelihood of supportive public and private investment.â
SPG Coalition: CIMMYT is a leading organization for climate-smart agriculture, nutrient-use efficiency, and pest and fertilizer management
The Coalition on Sustainable Productivity Growth for Food Security and Resource Conservation (SPG Coalition) brings together researchers, non-governmental organizations, and private sector partners to advance a world with greater access to nutritious food and affordable diets. The Coalition recognizes that increasing the productivity of natural resources through climate adaptation and mitigation is instrumental to reaching this goal.
In a recent report, the SPG Coalition provides a path forward for NGOs, research institutions, and government agencies to strengthen agrifood and climate policies. The report contains real-life, evidence-based examples to further the sustainable production and conservation of natural resources, detailing the potential impacts on social, economic, and environmental conditions.
CIMMYT features prominently in the report as a leading organization focused on 4 main areas: climate-smart agriculture, nutrient-use efficiency (NUE), and pest and fertilizer management.
Nutrient-use efficiency and fertilizer management
While chemical fertilizers increase crop yields, excessive or improper use of fertilizers contributes to greenhouse gas emissions (GHG) and increases labor costs for smallholders. Efficient NUE is central to nutrient management and climate change mitigation and adaptation.
In India, CIMMYT, along with the Borlaug Institute for South Asia (BISA), CGIAR Research Centers, and regional partners, tested digital tools like the Nutrient Expert (NE) decision support tool which measures proper fertilizer use for optimized yields and provides nutrient recommendations based on local soil conditions.
The majority of smallholders who applied the NE tool reported higher yields while emitting less GHG emissions by 12-20% in wheat and by around 2.5% in rice as compared with conventional fertilization practices. Farmers also recorded double economic gains: increased yields and reduced fertilizer costs. Wider government scaling of NE could enhance regional food security and mitigate GHG emissions.
The Feed the Future Nepal Seed and Fertilizer (NSAF) project, led by CIMMYT and USAID, advocates for climate-smart agriculture by linking smallholders with improved seed, providing capacity-building programs, and promoting efficient fertilizer use. With a vast network established with the support from the Government of Nepal, NSAF successfully provides smallholders with expanded market access and nutritious and climate-resilient crop varieties.
Climate-smart maize breedingÂ
Since its arrival to sub-Saharan Africa (SSA) in 2016, fall armyworm (FAW) has devastated maize harvests for countless smallholders on the continent. Economic uncertainty caused by unstable yields and climate stressors like drought coupled with this endemic pest risk aggravating food insecurity.
CIMMYT and NARES Partner Institutions in Eastern and Southern Africa are spearheading a robust pest management project to develop, screen, and introduce genetically resistant elite maize hybrids across SSA. South Sudan, Zambia, Kenya, and Malawi have already deployed resistant maize varieties, and eight other countries in the region are projected to release their own in 2023. These countries are also conducting National Performance Trials (NPTs) to increase awareness of host plant resistance for the sustainable control of FAW and to sensitize policymakers on accelerating the delivery of FAW-tolerant maize varieties.
The establishment of FAW screening facilities in Africa permits more rapid detection and breeding of maize varieties with native genetic resistance to FAW, facilitating increased deployment of these varieties across Africa. The sustainable control of FAW demands a rapid-response effort, overseen by research organizations and governments, to further develop and validate genetic resistance to fall armyworms. Achieving greater impact for maize smallholders is critical to ensuring improved income and food security in Africa. It is also paramount for biodiversity conservation and removing labor burden on farmers applying additional synthetic pesticides to prevent further losses by the pest.
âThe SPG Coalition report emphasizes the power of partnership to enhance financial and food security for smallholder communities in the Global South. This is fully in line with the recently launched CIMMYT 2030 strategy. Itâs also an important reminder to assess our strong points and where more investment and collaboration is needed,â said Bram Govaerts, CIMMYT director general.
Climate Adaptation Atlas will support evidence-based solutions in Sri Lanka
We are all aware the immense challenges countries face due to climate change, particularly its impacts on vital sectors like agriculture, forestry and livestock. The agriculture industry is profoundly affected by unpredictable weather patterns and frequent incidences of extreme events such as floods, droughts and landslides. Consequently, finding effective solutions to address these issues becomes of paramount importance. Climate-resilient agriculture necessitates the adoption of sustainable crop and land management technologies.
In the context of South Asia, Sri Lanka stands out as one of the most severely affected countries by the impacts of climate change. The nation contends with a multitude of hazards, ranging from floods and landslides in the western and southwestern regions, drought and pest outbreaks in the northern region and coastal erosion along the coastal belts. These examples underscore the growing complexity and challenges associated with managing climate risks and patterns, especially when multiple hazards occur simultaneously.
In response, Sri Lanka has implemented climate-smart agricultural interventions, including the development and introduction of stress-tolerant crop varieties, rainwater harvesting, the introduction of energy-efficient irrigation systems, implementation of soil and water conservation programs and crop diversification. However, the agricultural sector still faces formidable challenges. There is a lack of up-to-date information on climate change and its impacts, a fragmented institutional setup, overlapping mandates and limited capacity for information sharing. To address these issues, we require zone-based planning and institutional collaboration. Integrating spatial considerations into rehabilitation and development interventions is the main consensus among stakeholders. All ongoing and planned programs need vulnerability information, and there is a consensus among stakeholders on the need to integrate spatial considerations into rehabilitation and development interventions.
This is where the Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project becomes an invaluable asset in expediting Sri Lanka’s journey towards climate-smart agriculture. Recent evidence highlights the need for a comprehensive assessment of location-specific climate actions to bridge knowledge gaps within the country. Through the Atlas, we will quantify localized climatic risks today and, in the future, assess their likely impacts on agriculture and identify key adaptation options to mitigate these risks. This knowledge will strengthen Sri Lanka’s food security and reduce its vulnerability to climate-related hazards. By complementing traditional methods of risk characterization with novel approaches like intensity and frequency analysis of hazards and historical crop yields, our efforts will gain added efficacy.
ACASA, therefore, offers us a unique opportunity to foster collaboration, share knowledge and develop evidence-based innovative solutions to confront the challenges posed by climate change in Sri Lanka. It serves as a platform to connect hazards, practices, tools and adaptation options. By intertwining various aspects of climate change and gaining a deeper understanding of its spatial and temporal dimensions through the Atlas, Sri Lanka is steadfast in its commitment to building resilience and creating a sustainable future for generations to come.

CIMMYT director general and cropping system scientist to receive the 2023 Glenn Anderson Lectureship Award
The Canadian Phytopathological Society (CPS) will bestow on Bram Govaerts, director general of CIMMYT, the 2023 Glenn Anderson Lectureship Award, during the upcoming International Congress of Plant Pathology (ICPP2023) in Lyon, France, on August 21, 2023.
The award honors the legacy of Robert Glenn Anderson (1924-81), eminent Canadian agricultural scientist and former CIMMYT wheat research director who helped ignite in India the âgreen revolution,â a rapid modernization of agriculture during the 1960s-70s and by which that nation went from grain shortages and hunger to becoming a leading grain exporter.
A bioscience engineer and soil scientist who is a PhD graduate from Belgiumâs Katholieke Universiteit Leuven and has worked in Africa, Asia, and Latin America, Govaerts will give the keynote address âAgrifood system for a food and nutrition secure world: From efficiency to resilience,â describing in part the relevance of CIMMYT and its partnersâ work.
âEarly warning and surveillance systems are key to building resilience in food insecure communities and regions,â said Govaerts. âSupporting this, in concert with national agricultural research systems and private partners, CIMMYT crop breeding programs yearly disseminate dozens of disease resistant, climate resilient varieties of maize, wheat, and dryland cereals, where they are most needed.â
âThe Centerâs science and partnerships have helped prevent the spread of deadly crop pests and diseases in sub-Saharan Africa and South Asia,â he added, âand we have new âGlenn Andersonsâ who are doing exactly what is needed to strengthen global food security, with plant health innovations and systemic thinking.â
Borlaugâs wish: Take it to the farmer
Working with scientists, training specialists, extension agents, farmers, and communications and technology experts, a CIMMYT program led by Govaerts for over a decade in Mexico applied the admonition of Norman E. Borlaug, Nobel laureate and colleague of Anderson, to âtake it to the farmer,â combining the right seed with the right conservation agriculture production practices embedded in integrated markets, while recognizing and incorporating farmer knowledge.
âOngoing efforts of the Center and national and local partners are promoting the adoption of conservation agriculture-based sustainable intensification to transform food systems throughout the Global Southâ Govaerts explained. âThe training offered, and the advisory systems supported by CIMMYTâs work aim to empower women and disadvantaged social groups, while offering opportunities for fulfilling livelihoods to a new generation of farmers who will grow nutritious food for all.â
A CIMMYT scientist since 2007 as a Post-doctoral Fellow, Maize and Wheat based Cropping Systems Management, and current director general, in 2014 Govaerts received the World Food Prizeâs âNorman Borlaug Award for Field Research and Application from the World Food Prizeâ for the development and spread of sustainable agricultural systems. He is A.D. White Professor-at-Large at Cornell University and, in 2020, was elected a Fellow of the American Society of Agronomy (ASA) for outstanding contributions to the field of agronomy.
The Robert Glenn Anderson lecture series on the security of the world food supply was first given at joint meetings of the Canadian Phytopathological Society (CPS) and American Phytopathological Society (APS) in 1986 and an endowment fund was then established by the CPS. More recently, the Lecture has been given at the International Congresses of Plant Pathology (ICPP1998 to 2018).
As a Robert Glenn Anderson lecturer, Govaerts enters the hallowed company of other distinguished scientists who have been invited to give the address, including Norman E. Borlaug (1992); Per Pinstrup-Andersen, Emeritus Professor of Cornell University (2000), South African researcher Jennifer A. Thomson (2015); and late World Food Prize laureate and CIMMYT wheat director, Sanjaya Rajaram (2019).

Atlas crucial to strengthen Nepalâs capacity to cope with climate change
Nepal, like other South Asian nations, faces significant environmental challenges, including climate change and air pollution. The impacts of climate change in Nepal are profound, with species moving to higher elevations, glaciers melting and an increase in extreme precipitation events. Despite only contributing a fraction of global greenhouse gas emissions, Nepal ranks fourth on the Global Climate Risk Index. This vulnerability is attributed to the country’s unique geographical features, characterized by remarkable topographical variation spanning from 60 to 8,848 meters within just 190 kilometers from North to South. In addition to economic challenges and micro-climates, Nepal is highly susceptible to the consequences of climate change, particularly in the mid-and far-western hills and mountains.
To tackle these challenges, Nepal has taken proactive measures by implementing various adaptation strategies. Key initiatives include the National Adaptation Program of Action (NAPA), National Adaptation Plan (NAP 2021-2050), Agriculture Development Strategy (ADS-2015-2035) and the Green, Resilient, & Inclusive Development (GRID) plan. These initiatives have played vital roles in building resilience. Nepal has also launched the Climate-Smart Village program at the local level in all seven provinces, offering grassroots training on carbon and energy efficiency, biodiversity conservation and water management practices. Another notable achievement is the ‘The Himalayan Climate and Water Atlas,’ which utilizes data from five major river basins and historical climate records to project future climate hazards and extreme events.
Furthermore, Nepal developed the National Climate Change Policy (NCCP) in 2019, prioritizing eight thematic areas including agricultural and food security. The Vulnerability and Risk Assessment Report by the Ministry of Environment (2021) has also examined vulnerability and risks in eight thematic areas and one cross-cutting area for the preparation and implementation of the National Adaptation Plan. This report not only assesses the various dimensions (exposure, sensitivity, adaptive capacity, and risk) of climate change impacts across multiple sectors but also offers a range of adaptation options to address the adverse effects.
To successfully implement and translate the NCCP into action, it is crucial to identify where and how to invest. By aligning with the Atlas of Climate Adaptation in South Asian Agriculture (ACASA), Nepal reaffirms its commitment to addressing the intersection of agriculture and the environment. By leveraging the Atlas, Nepal will expedite its efforts to mitigate the impacts of climate change on agriculture, with a comprehensive understanding of various dimensions of risks and vulnerability. The Atlas will provide a detailed breakdown of risks specific to different commodities, enabling the development of effective mitigation and adaptation solutions.
By complementing ongoing efforts to manage risks and enhance adaptation strategies, the Atlas will serve as a testament to Nepal’s determination to strengthen its capacity to cope with climate change. It will make an invaluable contribution to climate change adaptation technologies, assisting government entities at all levels in formulating effective policy guidelines. By integrating research findings, indigenous knowledge, and cutting-edge technologies, the Nepal Agricultural Research Council (NARC) firmly believes that the Atlas represents another crucial step towards implementing a holistic approach to mitigate and adapt to the negative impacts of climate change on agriculture.

Bangladesh to improve risk characterization at a granular level with Atlas
Bangladesh is one of the most climate-vulnerable countries in the world. The climate risks are negatively impacting the country’s agricultural sector, which constitutes nearly 12% of the countryâs GDP. Additionally, 40% of the countryâs workforce rely on agriculture for a major portion of their income (BBS, 2021-22).
Despite these challenges, Bangladesh has demonstrated remarkable economic growth by strategically investing in climate resilience and disaster preparedness over the years. The country has gained global recognition as a leader in these areas, driving its overall development. However, escalating climate risks continue to pose threats to Bangladesh’s progress, particularly impacting the most vulnerable segments of society and jeopardizing the nation’s growth trajectory.
In response to these challenges, Bangladesh has made concerted efforts to develop climate adaptation strategies. A significant milestone was the launch of the GCA Global Hub on locally led adaptation by the Honorable Prime Minister Sheikh Hasina in 2022. This groundbreaking initiative aims to support one million climate-vulnerable migrants in Bangladesh. The government has also formulated policies, plans and programs to combat the impacts of climate change. The Bangladesh Climate Change Strategy and Action Plan (BCCSAP), formulated in 2009 and updated in 2022, focuses on six thematic areas, with five and six emphasizing adaptation and mitigation, respectively. Another important initiative is the Bangladesh Delta Plan 2100, prepared in 2017, which categorizes the entire country into six hotspots. To safeguard the agricultural sector from climate change, Bangladesh has also developed vulnerability Atlases such as the ‘Bangladesh Climate and Disaster Risk Atlas: Volume 1 & 2’ and the ‘Climate Adaptation Services Bangladesh (Haor region).’
While significant progress has been made in risk mapping, there is room for improvement. For instance, the current Atlases operate at the district level, and there is immense potential to downscale them to the upazila (sub-district) level to achieve enhanced granularity. Additionally, transforming the Atlases from report format to a more interactive and user-friendly online one would be beneficial.
The Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project aligns with the goals of BCCSAP, focusing on location-specific climate change adaptation and mitigation strategies in agricultural production. The Atlas will play a crucial role in quantifying localized climatic risks, assessing their impacts on agriculture today and in the future, and identifying key adaptation options to mitigate these risks. This knowledge will strengthen Bangladesh’s food security and reduce its vulnerability to climatic risks.
The Bangladesh Agricultural Research Council (BARC) will actively utilize the Atlas, leveraging agro-geospatial data to expedite decision-making processes. BARC will further leverage its expertise in geospatial tools, crop zoning information systems, GIS-based mobile apps, climate information databases and drought monitoring systems, further combined with the knowledge base of Atlas to ensure informed and evidence-based actions. Moreover, collaborating with ACASA to develop an advanced and interactive online Atlas expands the country’s scope and fosters stakeholder participation, enabling informed decision-making and refined risk characterization at a granular level.

Adaptation Atlas is a positive step towards climate resilient agriculture
India holds an impressive record in agricultural production. We are among the largest producers of milk, pulses, tea, spices, cashew, jute and bananas. Additionally, we rank as the second-largest producer of wheat, rice, fruits and vegetables. Our agricultural sector has experienced notable growth, with production increasing from 3 to 127 times since the 1970s. We have also witnessed a substantial boost in agricultural productivity, with yields per hectare rising from 0.7 to 2.3 tons during the same period.
Despite these achievements, we face pressing challenges that threaten our agricultural landscape. Water scarcity, soil degradation, pest and disease outbreaks, and the intensifying impacts of climate change need urgent attention.
In India, we observe that minimum temperatures are rising faster than maximum temperatures. We also witness a more pronounced temperature increase during the rabi (winter) season than the kharif (monsoon) season. Rainfall is becoming more variable with increasing episodes of extreme rainfall. These climate risks increase our food and livelihood insecurity.
We need advanced technological interventions and optimized resource allocation to address these challenges. Our development path, “Amrit Kaal,” necessitates climate-friendly practices prioritizing low carbon, water, nitrogen and energy usage. To further realize this vision, adopting 5Ms based on better markets, regional planning for monsoons, improved mechanization, management of micro-irrigation and new fertilizers, and mainstreaming the insurance is pivotal.
India has undertaken research, development and policy initiatives to build resilience in our food production system. However, the growing challenges of climate extremes demand sustained global efforts. The Indian Council of Agricultural Research (ICAR) therefore, welcomes international collaboration to exchange experiences and knowledge in climate action. We believe that collective efforts and shared expertise will strengthen our adaptation strategies.
In this regard, the Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project can play a vital role. ICAR is glad to support ACASA and will deploy a team of young scientists to contribute to and benefit from this Adaptation Atlas. Furthermore, we are pleased to offer our website as a platform to host the Atlas, facilitating its broader utilization within our country. We thank the Borlaug Initiative in South Asia (BISA) and the Bill and Melinda Gates Foundation (BMGF) for initiating this project in India.
Together, let us pave the way toward a climate-resilient future for agriculture, safeguarding our farmers’ livelihoods and securing food for future generations.

Building technical capacity for emerging agri-research science and big data management
Working alongside smallholder farmers, the Cereal Systems Initiative for South Asia (CSISA) project, has forged partnerships at the state and center levels to bridge the gap between innovation and the adoption of sustainable agricultural systems. In its current phase (2022-2025) in India, CSISA is helping mainstream innovation processes into the programing of national and state institutes through joint extension and research activities, including capacity building initiatives. Chaudhury Charan Singh Haryana Agriculture University (CCSHAU) is one of Asiaâs biggest agricultural universities, located at Hisar in state of Haryana, India. Initially a campus of Punjab Agricultural University, Ludhiana, it became an autonomous institution in 1970 and contributed significantly to both the Green and White Revolutions in India.
Together with CCSHAU, CSISA recently initiated a landscape diagnostic survey (LDS) under the universityâs rural agricultural work experience (RAWE) program for students graduating with an honors Bachelor of Science in agriculture. The twin objectives of this initiative were to gain an understanding of the existing challenges and opportunities for different cropping systems in Haryana through a bottom-up approach and to prepare students for careers in agriculture by building their practical skills in digital agriculture and big data management. This, explained CCSHAU Vice Chancellor B.R. Kamboj, who led the collaboration with CSISA, would provide recent graduates with the opportunity to âdesign a survey schedule, collect data in digital format, understand how farmers are adopting new technologies, and the learnings and challenges associated with each cropping system.â
Developing solutions for tomorrowâs problems
The predominant cropping systems practiced within the three ecologies of Haryana state are: the rice-wheat cropping system (RWCS); the cotton-wheat cropping system (CWCS); and the pearl millet-mustard cropping system (PMCS). The landscape diagnostic survey was carried out in parts of Sirsa and Hisar districts (for CWCS), Rewari and Mahendergarh districts (for PMCS) and Panipat, Yamunanagar, and Kurukshetra districts (for RWCS). The entire survey design was based on farmersâ participatory engagement and the cropping system framework.
A thorough process of survey design, including the training of master trainers, followed by orientation for students, was undertaken by the universityâs RAWE faculty with support from CSISAâs technical team and participating KVKs. Students collected data from farming households using questionnaires and analyzed them using different analytical tools and techniques. Based on farmersâ responses, important data points about the regionâs three crucial cropping systems were recorded and a book entitled Cropping Systems of Haryana â Challenges and Opportunities was published earlier this year, documenting the research process, data generated, results, and conclusions.
This has been a unique experience for both students and faculty that culminated in a research program with hands-on training. In the long run, this approach to capacity building for students is expected to support fieldwork and studies that help develop solutions to tomorrowâs problems in agricultural development. âThe commitment of CCSHAU to implement a strong RAWE program under the technical guidance of CSISA, with support from the district KVKs, and student participation made this publication a strong endorsement and reference for similar RAWE programs across states and central universities,â acknowledged Peter Craufurd, CSISA project lead for India.
Lessons from the field
The survey helped build studentsâ capacity to design and understand data collection methods, analysis, and management with actual field exposure. Additionally, the qualitative data-gathering experience allowed them to develop their understanding of farmersâ perspectives in adopting or rejecting a particular technology or recommendation. Sharing her experience of the field sessions, RAWE student Muskanâ group leader for the rice-wheat cropping system survey, said, âThis process of data gathering, and field exposure is very motivating. I have a better understanding of our farmersâ practices and challenges.â
Another participating RAWE student and group leader for the cotton-wheat cropping system survey, Nilanchal Nishan said, âthis exposure has helped me understand how policies and technology advancements affect farmers and their interaction with these changes over the yearsâ.
âThe entire process, from training to data management and curation, was fascinating for us,â said Aman Kumar, who led the pearl millet-mustard cropping system (PMCS) survey. He added that such field exposure will make students more aware of the trends and prevalent practices in the agricultural sector and help them choose their future field of research and study in a way that is in sync with real-time developments. These sentiments were echoed by RC Aggarwal, deputy director general for education at the Indian Council of Agricultural Research (ICAR), who called for more collaborations and capacity development exercises of this nature to be initiated in other state agriculture universities.

Set an example of how to thrive
In July 2023, CIMMYT launched a new seminar series on womenâs leadership â Catalysts of Change: Women Leaders in Science. Pitched as a âTED Talk meets fireside chatâ, the series shines a spotlight on successful women who are leaders in their fields, providing a platform for them to share insights from their lives and careers. Taking into consideration the fact that leadership can take make many different forms, the talks will highlight women who are leaders in all sorts of disciplines and capacities.
“We want more women leaders in science organizations and institutions like our own,â explains CIMMYT Director General Bram Govaerts. âTo achieve this goal we need proper representation, and we need role models that balance science, business insights and decision-making to provide opportunities to hear from women leaders about their life journeys, lessons and insights.â
Disruption without destruction
The second event in the series, held online on July 18, featured presentation by Altagracia GĂłmez Sierra, a leader in sustainable business, Chair of Mexicoâs Western Business Promoter Council, and one other the most influential women in agribusiness and energy within the region. During her talk, GĂłmez emphasized that while many challenges persist, social and political changes across the world are presenting new opportunities for women to advance in leadership roles.
âAs we enter a time of absolute change in this new decade, I think women have their best shot at stopping the reproduction of poverty and entering into leadership positions that were previously denied to them,â she said. âAnd in doing so, we should learn to be disruptive without being destructive. We should build on what we already have and keep pushing it forward.â
GĂłmez pointed to the advantage of being trained to develop soft skills, which companies and recruiters increasingly see as equally valuable as technical ones. âI think women are trained, even as young girls, to be very effective communicators. They are trained to be part of larger teams or communities and to advance forward without leaving people behind,â she told attendees. âI think thatâs an attribute that women â and you as women in science â can bring to the table and communicate. And that is something that I believe, whether it’s in the short or long term, does eventually get recognized.â
Help girls aspire to leadership
GĂłmez also outlined the importance of supporting womenâs leadership at all ages, and crucially even before entering the workforce. âWhat we sometimes fail to realize is that true innovation comes from the small businesses that constitute up to 76% of new jobs worldwide. And that 90% of companies are still family-run. So, when we think about changing companies, we need to think about changing families and how families work,â she explained. âBecause if we truly want to give women a shot, we need to give girls a shot.â
“I would invite every one of you, if you have girls at home, to encourage them not only to be prepared to take on leadership roles, but also to aspire to them,â she added. âYou can do this by setting an example of how to thrive.â
âI believe that the decade of the 2020s, in spite of all the challenges, is truly a wonderful opportunity for girls and women across the world â especially in science.â She ended her talk by encouraging attendees to do anything they can to enhance inclusion â particularly enhancing the accessibility of infrastructure, technology, and education for rural communities â in order to advance business objectives with social as well as economic profitability.
GĂłmezâ presentation was followed by a Q+A session led by Maria Itria Ibba, head of the Wheat Quality Laboratory and cereal chemist at CIMMYT. The full discussion can be viewed online here. Spanish and French-language audio is also available.
A new Climate Adaptation Atlas to safeguard South Asian agriculture
Climate change is no longer a distant threat but a reality that profoundly affects our lives. Among the most vulnerable regions to climate change, South Asia stands out because it is home to over 100 million farmers and produces over 285 million metric tons of milled rice and 128 million metric tons of wheat (FAO 2020-21). Among 193 countries worldwide, South Asian countries rank in the top quarter for climate risk and are experiencing rising meteorological and climate-related disasters. These pose significant challenges to farmers and the 216 million people in South Asia living in extreme poverty (World Bank, 2018), further jeopardizing their food security and livelihoods.
Considering this, with support from the Bill & Melinda Gates Foundation, the Borlaug Institute for South Asia (BISA) is working with national agriculture research systems in South Asia to develop the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).
The Atlas brings together spatially explicit South Asian data on the nature and evolving patterns of climate hazards. It will assess climate risks using gridded, village-scale analyses and through historical crop yield data and satellite signatures. The Atlas will consider the exposure of smallholder populations, farms and crop and livestock enterprises. It will assess the vulnerability or adaptive capacity of those populations and impacts on the regionâs critical commodities. Importantly, the Atlas will provide a unique set of on-line tools and a portfolio of adaptation options to underpin better decisions regarding investments in agricultural technologies, climate information services, and policies. The project will also focus on building the capacity of concerned stakeholders such as multi-lateral agencies, government bodies, NGOs, and the private sector in the use of Atlas assets, through training materials, tutorials, and periodic workshops. This will enable informed investments and policy decisions to benefit 100 million farmers in South Asian region. For wider use, the Atlas will be embedded online as an open-source, web-enabled and interactive and dynamic tool for easy access by all concerned stakeholders.
Drawing on the expertise and experience of South Asian nations such as Bangladesh, India, Nepal, and Sri Lanka, which have suffered from extreme heat, prolonged droughts, and severe flooding in key crop-producing areas, ACASA represents an example of collaboration and knowledge exchange to reduce farmers’ risks and offer them ways to adapt.
BISA and CIMMYT are pleased to anchor this remarkable collaboration that leverages multi-disciplinary expertise and perspectives to address the complex challenges posed by climate change, linking the detailed characterization of climatic risks with mitigation technologies and policies to meet the needs of diverse stakeholders. The proposed work will contribute actively to the CIMMYT2030 Strategy where one of the 5 impact areas is centered around Climate adaptation and Mitigation. The entire strategy designs a path toward a Food and Nutrition Secure world through science and innovation in the midst of a global climate crisis.
Established in 2011 by CIMMYT and the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) is a non-profit international organization that applies advanced technologies to improve food systems and food security, nutrition, livelihoods, and the environment in South Asia, home to more than 300 million undernourished people.
