In August 2022, the arrival of a container ship at the port in Cotonou, Benin signaled a major milestone in a developing South-South business relationship that holds the potential to produce a massive change in agricultural practices and output in Benin and across West Africa.
The delivery of six-row seeder planters from India marks the initial fruit of a collaboration between Indian manufacturer Rohitkrishi Industries and Beninese machinery fabricator and distributor Techno Agro Industrie (TAI) that has been two years in the making.
Connecting partners in the Global South
A major area of focus for the Green Innovation Centers for the Agriculture and Food Sector (GIC) projects launched in 15 countries by Germanyâs Federal Ministry for Economic Cooperation and Developmentâs special initiative One World No Hunger is fostering cooperation between nations in the Global South.
This story began through the partnership between the Green Innovation Centers for the Agriculture and Food Sector and The International Maize and Wheat Improvement Center (CIMMYT) to increase agricultural mechanization in 14 countries in Africa and 2 in Asia.
GIC in India has been working with Rohitkrishi to develop appropriate mechanization solutions for smallholding farmers in India since 2017.
Under this new cross-border goal, GIC India discussed with Rohitkrishi the opportunity to adapt machines to the agroecological and socio-economic systems of African countries where continued use of traditional farming methods was drastically limiting efficiency, productivity, and yield. Rohitkrishi assessed the need and pursued this opportunity for long-term business expansion.
Small machines for smallholders
Before connecting with farmers and manufacturers in Benin, Rohitkrishi was busy solving problems for smallholding farmers in India, where large manufacturers focus on agricultural machinery designed and produced to meet the needs of the bigger, commercial farms. Sameer Valdiya of GIC India and Sachin Kawade of Rohitkrishi put their heads together to develop a plan for producing machines that could make a differenceâand then convince smallholding farmers to try them.
By adapting an existing machine and incorporating continuous feedback from farmers, they created a semi-automatic planter. This unique, co-creative process was accompanied by an equally important change in farmer mindset and behaviorâfrom skepticism to the demonstrated impact and cost-benefit of the planter that was clear to each farmer.
These farmers were the first to adopt the technology and promoted it to their peers. Their feedback also drove continued improvementsâa fertilizer applicator, new shaft and drive, safety features, night-lights and (perhaps most importantly) a multi-crop feature to make it useful for planting potatoes, ginger, and turmeric.
Today, Rohitkrishi has distributed 52 semi-automatic planters across India, and these machines are being used by up to 100 farmers each. Users are seeing a 17-20 percent increase in productivity, with an accompanying increase in income, and 30 percent of users are women.
The seeders are a roaring success, but Rohitkrishi is focused on continued improvement and expansion. As they continue to respond to adjustments needed by farmers, the company plans to sell 1000 semi-automatic planters per year by 2025. Reaching that goal will require both domestic and foreign sales.
Market opportunity meets technological need
Thanks to the active partnership of CIMMYT and Programme Centres dâInnovations Vertes pour le secteur agro-alimentaire (ProCIVA), TAI in Benin emerged as a promising early adopter of Rohitkrishiâs planters outside India. Seeing a remarkable opportunity to establish a foothold that could open the entire West African market to their products, Rohitkrishi began the painstaking process of redesigning their machine for a new context.
This ambitious project faced numerous challengesâfrom language barriers, to the definition of roles amongst major players, to major COVID-19 and supply chain delays. The arrival of the seeders, however, is a major accomplishment. Now Rohitkrishi and TAI will begin working with government representatives and farmer-based organizations to ensure the equipment performs well on the ground and meets Beninâs agroecological requirements.
Once final testing is completed in the coming months, Rohitkrishiâs seeders will have the chance to demonstrate what a difference they can make for soy and rice production in Benin.
âWhen developing countries with similar contexts and challenges forge alliances and business connections to share their knowledge, expertise, and problem-solving skills with each other, this kind of direct South-South collaboration produces the most sustainable advances in agricultural production, food security, and job creation,â said Rabe Yahaya, agricultural mechanization specialist at CIMMYT.
Meanwhile, CIMMYT is studying this pilot project to identify opportunities for reproducing and expanding its success. Through the Scaling Scanâa web-based, user-friendly tool to assess ten core ingredients necessary to scale-up any innovationâCIMMYT is helping Rohitkrishi and TAI set ambitious and reachable goals for scalability.
Most importantly, the Scaling Scan results will identify areas for course correction and help Rohitkrishi and its partners continue to be sensitive to farmer feedback and produce equipment better suited to needs on the ground.
In sub-Saharan Africa, 85% of the population couldn’t afford an energy- and nutrient-sufficient diet. In the 12 most afflicted countries, World Bank data shows 9 out of 10 people struggle to afford a nutritious meal.
Climate change aggravates risk to make food even more unaffordable and crops more susceptible to crop pests and diseases.
CIMMYT maize research guides startups and nonprofits across Africa to act and put pressure on public and private actors to avert food insecurity and regional instability.
As climate change threats accelerate, new technologies, products, and approaches are required for smallholder farmers to mitigate and adapt to current and future threats. Targeting smallholder farmers will benefit not only the farmers but the entire agri-food system through enhanced locally relevant knowledge that harnesses handheld sensors and advisories on management options, soil status, weather, and market information.
The Agriculture Innovation Mission for Climate (AIM for Climate / AIM4C) seeks to address climate change and global hunger by uniting participants to significantly increase investment in, and other support for, climate-smart agriculture and food systems innovation over five years (2021â2025).
The International Maize and Wheat Improvement Center (CIMMYT), as a partner of AIM for Climate, organized a breakout session titled “Smart Smallholder Fertilizer Management to Address Food Security, Climate Change, and Planetary Boundaries” during the AIM for Climate Summit in Washington DC, May 8-10, 2023.
Fertilizers are essential for increasing crop yields and ensuring food security, yet fertilizer use for food and fodder is severely skewed at the global level, leading to over-fertilization in some regions and under-fertilization in others.
Farmers in low-income countries are highly vulnerable to fertilizer supply shortages and price spikes, which have direct consequences for food prices and hunger. Improving fertilizer efficiency and integrated organic and inorganic sources is important globally as nutrient loss to the environment from inappropriate input use drives greenhouse gas emissions and pollution.
Innovation Sprint
Because smallholder farmers are the primary managers of land and water, the CIMMYT-led AIM4C Innovation Sprint, Climate-Resilient soil fertility management by smallholders in Africa, Asia, and Latin America is designed to implement and scale-up a range of climate robust nutrient management strategies in 12 countries, and to reach tens of millions of smallholder farmers in close collaboration with nearly 100 public-private partners organizations.
Strategies include innovations in extension where digital tools enable farmer-centered private and public advisories to increase the uptake of locally adapted nutrient management practices. Connecting farmers to investors and markets provides financial support for improved nutrient management.
By tailoring validated fertility management practices to their specific conditions, and integrated use of legumes and manure, smallholders will optimize productivity, enhance climate resilience, and mitigate greenhouse gas emissions. Research from other organizations has determined that improved fertilizer management can increase global crop yield by 30% while reducing greenhouse gas emissions.
Right place, right time
âWe need locally adapted fertilizer management approaches that work for smallholder farmers. By tailoring validated fertility management practices to their specific conditions, smallholders will optimize productivity, enhance climate resilience, and mitigate greenhouse gas emissions,â said Sieg Snapp, CIMMYTâs Sustainable Agricultural Systems Program Director. She continued, âWhat is needed now is major investment in data synthesis. Through this SPRINT we are exploring options to enable taking sensors to scale, to reach tens of millions of farmers with hyper-local soils information.â
Inequality is the core of the problem in fertilizer management: some regions apply more than the required amount, where in other regions fertilizer application is insufficient for plant needs, leading to low yields and soil degradation.
âFertilizer efficiency can be improved through application of the right amount of fertilizer using the right source employing the right methods of application at the right time of plant demand,â said Tek Sapkota, CIMMYT Senior Scientist, Agricultural System/Climate Change.
The session included presentations by the Foundation for Food & Agriculture Research (FFAR), UN Foundation, Pakistan Agricultural Research Council (PARC), Stockholm International Water Institute (SIWI), USDA, and Alliance of CIAT-Bioversity. Highlights sustainable and climate-smart practices in Pakistan, novel plant genetics for improved nitrogen cycling, and soil water and nutrient management in the Zambezi to tackle food security and climate change challenges.
AMES, IOWAâThe Council for Agricultural Science and Technology (CAST) has announced the 2023 Borlaug CAST Communication Award goes to Alison Bentley.
While Bentley is known for her global research on wheat genetics, she is also recognized for her proficiency in science communication. Bentley has a passion for delivering practical applications from innovation to farmers, extensive reach through communicating and influencing, and mentoring and support of individuals and community efforts. Bentley’s exceptional work in raising awareness about the importance of wheat as a food crop is also evidenced by her wide-ranging list of communication activities.
In 2022 alone, Bentley delivered 20 scientific presentationsâincluding five international keynote talks and 15 additional invited talks. Bentley focused her communication efforts around two major areas. The first area was her rapid, science-led response to the impact of the Russian/Ukraine war on global wheat production through a communication article in Nature, followed with a social media campaign and numerous presentations and invited policy briefings. Her second area of focus was a major communications campaign by initiating and leading the Women in Crop Science network. This network was developed to address key issues such as the promotion and championing of females throughout their research careers, creating equal opportunities, and increasing visibility of members.
The extensive breadth of Bentleyâs outreach ranges from classic science presentations and open access articles to blogs, podcasts, YouTube videos, and Twitter campaigns. All these formats demonstrate her commitment to science communication and reaching as wide an audience as possible in an accessible way to engage with important, current topics regarding wheat supplies and plant breeding.
The official presentation of the award will take place at a special side event during the World Food Prize Borlaug Dialogue event in Des Moines, Iowa, in October. The Borlaug CAST Communication Award honors the legacy of Norman Borlaug, a Nobel Prize winner and author of the first CAST publication, and Dr. Charles A.

The United Nations declared 2023 as the International Year of the Millet.
Millet, with other resilient cereal crops, provides a nutritious and affordable option to families worldwide. CIMMYT and ICRISAT are scaling-up millet cultivation when climate change has placed pressure to protect the food systems that safeguard food security in Africa.
Bram Govaerts, CIMMYT Director General, promotes 5 adaptation measures that can transform global agri-food systems, making them more resilient to climate shocks to help vulnerable regions cope with diminishing yields and forced migrations.
Public and private crop research organizations worldwide have worked behind the scenes for decades, bolstering the resilience of staple crops like maize and wheat to fight what is shaping up to be the battle of our time: feeding humanity in a biosphere increasingly hostile to crop farming.
In the case of wheat â which provides some 20% of carbohydrates and 20% of protein in human diets, not to mention 40% of total cereal exports â harvests spoiled by heat waves, droughts, and crop disease outbreaks can send food prices skyrocketing, driving world hunger, poverty, instability, human migration, political instability, and conflict.
Century-high temperature extremes and the early onset of summer in South Asia in 2022, for example, reduced wheat yields as much as 15% in parts of the Indo-Gangetic Plains, a breadbasket that yearly produces over 100 million tons of wheat from 30 million hectares of crop land.
Around half the worldâs wheat crop suffers from heat stress, and each 1 °C increase in temperature reduces wheat yields by an average 6%, according to a 2021 review paper âHarnessing translational research in wheat for climate resilience,â published in the Journal of Experimental Botany, which also outlines nine goals to improve the climate resilience of wheat.
Droughts and shrinking aquifers pose equally worrying threats for wheat, said Matthew Reynolds, a wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the study. âWater availability is the biggest factor influencing potential yield in a majority of wheat environments globally,â Reynolds explained. âStudies predict severe water scarcity events for up to 60% of the worldâs wheat-growing areas by the end of this century.â
Science and sources to toughen wheat
Along with modernized, more diverse cropping systems and better farm policies, more resilient varieties are crucial for sustainable wheat production, according to Reynolds and a wheat breeder colleague at CIMMYT, Leo Crespo, who added that breeders have been working for decades to stiffen wheatâs heat and drought tolerance, long before climate change became a buzzword.
âBreeding and selection in diverse environments and at targeted test sites characterized by heat and natural or simulated drought has brought farmers wheat varieties that perform well under both optimal and stressed conditions and weâre implementing new technologies to speed progress and lower costs,â said Crespo, mentioning that the Centerâs wheat nurseries SAWYT and HTWYT target semi-arid and heat-stressed environments respectively and are sent yearly to hundreds of public and private breeders worldwide through the International Wheat Improvement Network (IWIN). “Retrospective analysis of IWIN data has shown that heat tolerance has been increasing in recent years, according to a 2021 CIMMYT study.”
âClimate change is a serious driver of potential disease epidemics, since changeable weather can increase selection pressure for new virulent pathotypes to evolve,â said Pawan Singh, a CIMMYT wheat pathologist. âWe must be ever vigilant, and the IWIN is an invaluable source of feedback on potential new disease threats and changes in the virulence patterns of wheat pathogens.â
In the quest to improve climate resilience in wheat, CIMMYT âpre-breedingâ â accessing desired genetic traits from sources like wheatâs grassy relatives and introducing them into breeding lines that can be crossed with elite varieties â focuses on specific traits. These include strong and healthy roots, early vigor, a cool canopy under stress, and storage of water-soluble carbohydrates in stems that can be used as stress intensifies to complement supplies from photosynthesis, as well as an array of traits that protect photosynthesis including âstay-greenâ leaves and spikes and pigments that protect the delicate photosynthetic machinery from oxidative damage caused by excess light.
Though elite breeding lines may contain genetic variation for such traits, in pre-breeding researchers look further afield for new and better sources of resilience. The vast wheat seed collections of CIMMYT and other organizations, particularly seed samples of farmer-bred heirloom varieties known as âlandraces,â are one potential source of useful diversity that cutting-edge genetic analyses promise to help unlock.
Rich diversity for wheat is still found in farmersâ fields in India, in the northern states of the Himalayan region, the hill regions, and the semi-arid region of Rajasthan, Gujarat, Karnataka. The landraces there show tolerance to drought, heat, and saline soils.
The so-called âsynthetic wheatsâ represent another plentiful source of resilience genes. Synthetics are the progeny of crosses of tetraploid wheat (having four chromosomes, like the durum wheat used for pasta) with wild grass species. CIMMYT and other organizations have been creating these since the 1980s and using them as bridges to transfer wild genes to bread wheat, often for traits such as disease resistance and heat and drought tolerance.
The study, creation, and use of bridging lines, landraces, and seed collections with useful traits as part of pre-breeding is described in the 2021 paper âProgress and prospects of developing climate resilient wheat in South Asia using modern pre-breeding methods,â published in the science journal Current Genomics.
Lines with new sources of heat- and drought-tolerance from CIMMYTâs pre-breeding are also distributed to public and private breeders worldwide via the IWIN for testing as the Stress Adapted Trait Yield Nurseries (SATYNs), according to the paper. These special nurseries are grown by national and private breeders throughout South Asia, for example in Afghanistan, Bangladesh, India, Iran, Nepal, and Pakistan. Lines from the nursery have on occasion been released directly as varieties for use by farmers in Afghanistan, Egypt, and Pakistan.
A critical challenge in pre-breeding is to identify and keep desirable wild genes while culling the undesirable ones that are also transferred in crosses of elite breeding lines with landraces and synthetics. One approach is through physiological pre-breeding, where complementary crosses are made to improve the crop performance under drought and heat stress. The second approach is using genomic prediction, on the basis of seeds, or accessions, in the gene bank collection that have gone through genomic and phenotyping analysis for target traits such as heat and drought tolerance. These approaches can also be combined to boost the speed and effectiveness of selecting strong varieties.
Breeding revolutions
Wheat breeding is being revolutionized by advances in âhigh-throughput phenotyping.â This refers to rapid and cost-effective ways to measure wheat performance and specific traits in the field, particularly remote sensing â that is, crop images taken from vehicles, drones, or even satellites. Depending on the wavelength of light used, such images can show plant physiochemical and structural properties, such as pigment content, hydration status, photosynthetic area, and vegetative biomass. Similarly, canopy temperature images from infrared photography allow detection for crop water status and plant stomatal conductance. Â âSuch traits tend to show better association with yield under stress than under favorable conditionsâ, said Francisco Pinto, a CIMMYT wheat physiologist who is developing methods to measure roots using remote sensing. âA remotely sensed âroot indexâ could potentially revolutionize our ability to breed for root traits, which are critical under heat and drought stress but have not been directly accessible in breeding.â
Innovative statistical analysis has greatly increased the value of field trials and emphasized the power of direct selection for yield and yield stability under diverse environments.
Initial results from genomic selection programs, particularly where combined with improved phenotyping techniques, also show great promise. The potential benefits of combining a range of new technologies constitute a valuable international public good.
New initiatives
Launched in 2012, the Heat and Drought Wheat Improvement Consortium (HeDWIC) facilitates global coordination of wheat research to adapt to a future with more severe weather extremes, specifically heat and drought. It delivers new technologies â especially novel wheat lines  to wheat breeders worldwide via the International Wheat Improvement Network (IWIN), coordinated for more than half a century by CIMMYT.
HeDWIC is supported by the Foundation for Food and Agriculture Research (FFAR) and is part of the Alliance for Wheat Adaption to Heat and Drought (AHEAD), an international umbrella organization set up by the Wheat Initiative to bring the wheat research community together and to exchange new germplasm, technologies and ideas for enhancing tolerance to heat and drought.

To address challenges caused by maize diseases and pests, AATF renews its commitment to the TELA maize project, which works towards the commercialization of transgenic drought-tolerant and insect-proof maize varieties to safeguard food security in Sub-Saharan Africa.
The Livestock Production Systems in Zimbabwe (LIPS-ZIM) project promotes climate-relevant innovation to better manage livestock disease and production systems.
Agrovita, which launched in 2021, aims to boost the productivity of 900 farmers over three years through actions that improve their communitiesâ food security by implementing regenerative farming practices across almost 30,000 acres. The program also aims to ensure that 50% of its beneficiaries are women.
Through decades-long Asian and global partnerships, the International Maize and Wheat Improvement Center (CIMMYT) is refining and spreading a suite of resource-conserving, climate-smart innovations for highly diverse maize- and wheat-based cropping systems, including more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations.
âZero-tillage and residue management for cereals â that is, sowing the seed directly into unplowed soils and residues from the preceding rice crop â has been adopted on a significant area in the transact of Indo-Gangetic Plain, with positive impacts on crop yields, profitability, and resource-use efficiencies,â said Tek Sapkota, senior scientist in agricultural systems/climate change, CIMMYT.
The paper âConservation agriculture for sustainable intensification in South Asia,â published in the science journal Nature Sustainability reported that, compared to the conventional practice, conservation agriculture resulted overall in a 4.6% higher grain yield, a 14.6% improvement in water use efficiency, and a 25.6% greater net economic return. The net economic return was 40.5% higher for full conservation agriculture but, given the benefits of partial adoption of the practices, rigid adherence to an âall or nothingâ approach to spread conservation agriculture in South Asia does not seem warranted.
Conservation agriculture also offers several ecosystem services. In the study data, global warming potential was reduced by as much as 33.5% in rice-wheat systems, values that are consistent with other research. Moreover, conservation agriculture-based practices provide an economically feasible alternative to burning rice residues, a serious public health threat in northwestern India given the roughly 23 million tons of residues that are burned each year in the region.
âMore widespread adoption of zero-tillage in India has been made possible with the development of next-generation tractor-drawn implements that allow direct seeding into heavy residues, as well as business models whereby implement owners contract out with neighboring farmers to sow their crops and provide other services,â said Sapkota. âNational governments in South Asia are actively promoting conservation agriculture to address residue burning and other farming sustainability problems.â
Fitting conservation agriculture to maize farming in Mexico
Efforts to adapt conservation agriculture and promote its adoption by farmers operating highly-diverse, mostly rainfed maize-based cropping systems in Mexico have had mixed results. A recent study assessed soil health in 20 trials in starting between 1991 and 2016 in agro-ecologies ranging from handplanted traditional systems to intensive irrigated systems, contrasting conservation agriculture effects with those of local conventional practices, which commonly involve tillage, residue removal, and continuous maize production.
As reported in the 2021 paper âEffects of conservation agriculture on physicochemical soil health in 20 maize-based trials in different agro-ecological regions across Mexico,â published in the science journal Land Degradation and Development, conservation agriculture increased maize yields at most sites by 0.85 tons per hectare, on average. Organic matter and nitrates were higher in topsoils under conservation agriculture and soil aggregate stability was greater, meaning the soil more effectively moved air and water to plant roots. For other soil health parameters, such as nutrient content, pH, or compaction, most values were determined more by local soil type than by crop management.
âGiven the significant variation across agro-ecologies, local adaptive trials are important to assess the effects of conservation agriculture on soil health and fit it to local conditions,â said Simon Fonteyne, a CIMMYT cropping systems agronomist and first author of the paper.
Emissions control
Several recent studies have assessed the costs and potential of various sustainable intensification technologies for reducing greenhouse gas emissions in India, Bangladesh and Mexico. Their findings can help inform national policies on food security, economic development and environment, including those relating to the Paris Agreement.
In the 2019 study âCost-effective opportunities for climate change mitigation in Indian agriculture,â published in the journal Science of the Total Environment, CIMMYT and partners found that estimated total emissions from Indian agriculture were 481 tons of CO2 equivalent (MtCO2e) in 2012, with crops contributing over 40% and livestock nearly 60%. Under a business-as-usual scenario, agricultural greenhouse gas emissions in India would be 515 MtCO2e by 2030. This annual emissions could be reduced by 85.5 MtCO2e through adoption of mitigation practices and about 80% of that reduction could be achieved through measures that would actually save money and, in many cases, could be implemented with current technology. The efficient use of fertilizer, zero-tillage, and rice-water management could deliver more than 50% of the technical abatement potential.
âRealization of this mitigation potential will depend largely on the extent adoption by farmers,â said Sapkota, who was lead author of the study. âLarge-scale adoption of apparently win-win options is not happening, so the government of India will need to apply appropriate policy measures and incentives, consistent with its food security and emission reduction goals.
A similar study in Bangladesh, reported in the 2021 paper âQuantifying opportunities for greenhouse gas emissions mitigation using big data from smallholder crop and livestock farmers across Bangladesh,â published in the journal Science of the Total Environment, found greenhouse gas emissions from agriculture in Bangladesh of 76.8 MtCO2e for 2014â15. Yearly emissions by 2030 under a business-as-usual approach would approximate 86.9 MtCO2e and, by 2050, about 100 MtCO2e. Adoption of realistic, climate-smart crop and livestock management options to reduce emissions offer mitigation opportunities of 9.51 MtCO2e per year by 2030 and 14.21 MtCO2e by 2050. As much as 75% of this potential can be achieved through cost-saving options that benefit smallholder farmers. As is the case for India, realization of this potential largely depends on the degree to which supportive policies and measures can encourage farmer adoption.
A similar rapid assessment of costs for to mitigate greenhouse gas emissions from crops, livestock, and forestry in Mexico found a national mitigation potential of 87.9 MtCO2eq per year, fully 72.3 MtCO2eq from livestock. As reported in the 2022 paper, âQuantification of economically feasible mitigation potential from agriculture, forestry and other land uses in Mexico,â published in the science journal Carbon Management, implementing mitigation potential on Mexican cropland could bring net benefits, compared to livestock and forestry options, which involve net costs. In the 2021 paper “Reduced Water Use in Barley and Maize Production Through Conservation Agriculture and Drip Irrigation” a reduction of emissions caused by lower fuel use in conservation agriculture of 192 kg CO2 haâ1 Â was measured in farmers fields, as well as an increase in soil carbon and a reduction in water use.
To provide a comprehensive overview of women and gender issues in agriculture, the Food and Agriculture Organization (FAO) recently released âThe status of women in agri-food systems,â which provides compelling examples of policies and programs with a review of what has worked and specific recommendations. The report concludes that increasing womenâs empowerment is essential for womenâs well-being and has a positive impact on agricultural production, food security, diets, and child nutrition.
Despite the importance of agrifood systems for womenâs livelihoods and the welfare of their families, womenâs roles are marginalized, and their working conditions are likely to be worse than menâsâirregular, informal, part-time, low-skilled, labor intensive and thus vulnerable.
The International Center for Maize and Wheat Improvement (CIMMYT) recognizes the pressing need for gender equality measures in agri-food systems and has initiated many specific projects to address gender equality. In addition, CIMMYT is committed to introducing a gender component into all its research, programs, and interventions.
âIt is an acknowledgment that gender and social equity has always been a critical component of the sustainability of any initiative, regardless of the crop and the geographic area affected,â said Bram Govaerts, CIMMYTâs Director General. âCIMMYT is now more intentional about addressing gender equality issues and we recognize the same old methods might not be the most effective.â
FAO: the collection of high-quality data are paramount for monitoring, evaluating and accelerating progress on gender equality in agrifood systems
In the past, many initiatives have relied on surveys to gather data from farmers, producers, consumers, and other stakeholders. However, in traditional rural societies, survey-based data collection might not be the best way to evaluate womenâs agency, as the deeply rooted cultural restrictions might not allow them to talk openly about sensitive issues, like their relationship with a spouse.
As part of the Accelerating Genetic Gains in Maize and Wheat for improved livelihoods in Asia and Africa (AGG) project, in Bihar India, CIMMYT researchers developed an innovative storytelling approach to data collection: using vignettes, farmers are given short stories to relate to their household circumstances. Stories are also easier to remember and help build a connection with the characters quickly.
This storytelling method debunked some long-held ideas about womenâs role in agriculture in this area of India, creating a more nuanced view of how and why women engage in agriculture. This method will lead to richer qualitative data, which can improve the development and sustainability of gender interventions.
FAO: Social protection programs have increased womenâs employment and enhanced womenâs resilience.
CIMMYTâs partnership with the Cereal Systems Initiative for South Asia (CSISA) specifically supports women farmers by improving their access and exposure to modern and improved technological innovations, knowledge and entrepreneurial skills. CSISA works in synergy with regional and national efforts, collaborating with public and private-sector partners.
FAO: interventions must be designed to close gender inequalities and empower women.
While CIMMYT has produced many improved maize varieties, CIMMYT researchers discovered that these new varieties may fall short in meeting the needs of women and the poorest of farmers. We need to explore novel approaches to evaluating farmer demand for seed, considering new questions instead of continuing to look for gender-based differences in preferences.
A first step in that direction is to determine how demand for maize seed differs among farmers according to their needs, priorities, and resource limitations. Gender is a large part of that equation, but the CIMMYT researchers also advocate for other considerations, like how maize fits into household food security and livelihoods, decision-making dynamics around maize production, and seed accessibility.
Internal efforts at CIMMYT
While the FAO report is focused on women in the agri-food system, CIMMYT has also engaged several internal initiatives to ensure a more diverse portfolio of researchers and to cultivate a stronger sense of inclusion at CIMMYT and in the wider scientific community.
At CIMMYT, between 20 and 25 percent of staff in the science career trackâcareers involving field, lab, data, and socioeconomic workâare female. In 2022, Alison Bentley, Director of CIMMYTâs Global Wheat Program, and Nele Verhulst, cropping systems agronomist started Women in Crop Science at CIMMYT. The group aims to connect and build a network of women in the science career track and commits to achieving a more inclusive environment at CIMMYT and within the Consultative Group for International Agricultural Research (CGIAR).
The group recently received the Inclusive Team award at the inaugural CGIAR Inclusive Workplace Awards.
CIMMYT is also helping to develop the next generation of women scientists through the annual Jeanie Borlaug Laube Women in Triticum Awards, which recognizes scientific excellence and leadership potential. To date., over 60 women scientists have received leadership training and professional development opportunities meant to support them as they join the community of scholars who are fighting hunger worldwide.

Smallholder farmers have long been considered purely subsistence producers without the capacity to participate in commercial value chains. This has led to their exclusion from many agribusiness enterprises which typically focus on medium- to large-scale growers.
Through the Accelerated Innovation Delivery Initiative (AID-I), the International Maize and Wheat Improvement Center (CIMMYT) and partners are supporting smallholder farmers to enter viable legume value chains. Soybean is one crop experiencing a rapidly expanding market. This is a unique opportunity for small-scale farmers to access a legume value chain, one that drives sustainable intensified farming for improved income and livelihoods.
In the Kasenengwa District, in eastern Zambia, Josephine Mbewe produces soybean for local oil production and grain traders who export the commodity to neighboring countries like Zimbabwe and Malawi. She is one of many farmers who are benefitting from the Agriculture Development Agent model, a concept that has been developed by CIMMYTâs implementation partner Catholic Relief Services (CRS) and scaled up in the AID-I project.
âFor years we always wanted to produce for the market, but the costs were just too high. In addition, we didnât exactly know who to sell to so this model really helps us as we sell our products locally but knowing that our aggregated produce will go to distant consumers. This model is helping us to have access to high quality inputs such as improved seed, crop chemicals, fertilizers, and other related products,â Mbewe said.
The Agriculture Development Agent model aims to create a consortium of village based agrodealers who double as seed producers multiplying seed and selling it to surrounding farmers. The same dealers buy back the grain and sell it to oil pressing companies and export commodity trading companies.
The AID-I project scales promising innovations with proven ability to address some of the systemic constraints that have discouraged agribusinesses from engaging with smallholder farmers.
âThis is a model that is leveraged on community social capital where trust exists between the ADA and the local farmer,â said James Nguluwe from CRS. âIssues related to seed diversion or side marketing of the harvested crop are kept at a bare minimum as farmers donât want to spoil their relationship with the Agriculture Development Agent and their general reputation within the community.â
âThe model is also catalytic to the use of improved seed as farmers have to produce using a particular seed type. The interactions with ADA over soya seed, production and reverse purchase set up has seen the farmers extending to procure improved maize varieties as well, as opposed to times past where they would recycle seed and reap poor harvests,â he said.
Paitana Mwanza, an ADA agreed and spoke of his positive experiences of the model.
âI have had no contractual breach with the farmers. When they buy the seed, we agree on a separate grain buy back arrangement â the farmers have always delivered as per agreement.â
For years, farmers have been growing recycled seed and use of improved seed has been very uncommon among smallholder farmers. Having a financial incentive where ADAs provide an assured market is proving to be a good enough incentive to facilitate behavioral change.
Agribusiness agents face high costs associated with aggregation of produce, which the Agriculture Development Agent model overcomes. Farmers are organized and supported by ADAs, who are registered market players that have been extensively trained in business practices, seed handling and seed and grain production. As such, both grain traders and processors can make a realistic profit through this innovative system that facilitates small-scale farmers accessing new markets.
One of the key objectives of the AID-I project is to ensure that participating in market systems is a choice for smallholder farmers and exclusion from viable value chains is a thing of the past. The Agriculture Development Agent model promises to transform not only eastern Zambia but the whole country at large.
