Theme: Climate adaptation and mitigation

Climate change threatens to reduce global crop production, and poor people in tropical environments will be hit the hardest. More than 90% of CIMMYT’s work relates to climate change, helping farmers adapt to shocks while producing more food, and reduce emissions where possible. Innovations include new maize and wheat varieties that withstand drought, heat and pests; conservation agriculture; farming methods that save water and reduce the need for fertilizer; climate information services; and index-based insurance for farmers whose crops are damaged by bad weather. CIMMYT is an important contributor to the CGIAR Research Program on Climate Change, Agriculture and Food Security.

Intercropping

Written by mcallejas on . Posted in Uncategorized.

The Intercropping project aims to identify options for smallholder farmers to sustainably intensify wide-row crop production through the addition of short-duration, high-value intercrop species and to help farmers increase their productivity, profitability and nutrition security while mitigating against climate change.

The focus is on intensification of wide-row planted crops: dry (rabi) season maize in Bangladesh, eastern India (Bihar and West Bengal states) and Bhutan, and sugarcane in central north India (Uttar Pradesh state). The primary focus is to sustainably improve cropping system productivity, however, the effects of wide-row, additive intercropping at the smallholder farm level will be considered, including potential food and nutrition benefits for the household.

There are many potential benefits of wide-row, additive intercropping, beyond increased cropping system productivity and profitability: water-, labor- and energy-use efficiencies; improved nutrition and food security for rural households; empowerment for women; and (over the longer term) increased soil health.

Little research has been conducted to date into wide-row, additive intercropping (as distinct from traditional replacement intercropping) in South Asian agroecologies. To successfully and sustainably integrate wide-row, additive intercropping into farmers’ cropping systems a range of challenges must be resolved, including optimal agronomic management and crop geometry, household- and farm-scale implications, and potential off-farm bottlenecks.

This project aims to identify practical methods to overcome these challenges for farming households in Bangladesh, Bhutan and India. Focusing on existing wide-row field crop production systems, the project aims to enable farmers to increase their cropping system productivity sustainably and in a manner that requires relatively few additional inputs.

Project activities and expected outcomes:

  • Evaluating farming households’ initial perspectives on wide-row, additive intercropping.
  • Conducting on station replicated field trials into wide-row, additive intercropping, focusing on those aspects of agronomic research difficult or unethical to undertake on farms.
  • Conducting on farm replicated field trials into wide-row, additive intercropping.
  • Determining how wide-row, additive intercropping could empower women. Quantify the long-term benefits, risks and trade-offs of wide-row, additive intercropping.
  • Describing key value/supply chains for wide-row, additive intercropping. Determine pathways to scale research to maximize impact.
  • Quantifying changes in household dry season nutrition for households representative of key typologies in each agroecological zone.

Ancient Wild Relatives Hold Key to Climate-Proofing Global Wheat Supply

Written by dmedina on . Posted in Press releases.

CIMMYT, Mexico, August 27, 2024 — Crop wild relatives that have survived changing climates for millions of years may provide the solution to adapting wheat, humanity’s most widely grown crop, to climate change. Two new studies led by the International Maize and Wheat Improvement Center (CIMMYT) reveal how tapping into this ancient genetic diversity can revolutionize wheat breeding and safeguard global food security.

As the weather becomes more erratic and extreme, wheat — providing 20% of all calories and protein globally and serving as the primary staple food for 1.5 billion people in the Global South — faces unprecedented threats. These include heat waves, delayed rains, flooding, and new pests and diseases.

“We’re at a critical juncture,” says Dr. Matthew Reynolds, co-author of both studies. “Our current breeding strategies have served us well, but they must now address more complex challenges posed by climate change.”

The research points to a vast, largely untapped reservoir of nearly 800,000 wheat seed samples stored in 155 genebanks worldwide. These include wild relatives and ancient, farmer-developed varieties that have withstood diverse environmental stresses over millennia. Although only a fraction of this genetic diversity has been utilized in modern crop breeding, it has already delivered significant benefits.

Proven impacts of wild wheat genes

One of the studies, a review published today in Global Change Biology (GCB)*, documents the immense impact of wild relatives’ traits, including on environmental sustainability. It finds that the cultivation of disease-resistant wheat varieties has avoided the use of an estimated 1 billion liters of fungicide just since 2000.

“Without transferring disease-resistant genes from wild relatives to wheat, fungicide use would have easily doubled, harming both human and environmental health,” says Dr. Susanne Dreisigacker, Molecular Breeder at CIMMYT and co-author of the review.

Sharing of new wheat breeding lines through the CIMMYT-led International Wheat Improvement Network, comprising hundreds of partners and testing sites around the world, increases productivity worth USD 11 billion of extra grain every year. The extra productivity has saved millions of hectares of forests and other natural ecosystems from cultivation.

The review highlights other key breakthroughs using wheat wild relatives, including:

  • Some experimental wheat lines incorporating wild traits show up to 20% more growth under heat and drought conditions compared to current varieties.
  • Genes from a wheat wild relative have generated the first crop ever bred to interact with soil microbes, reducing the production of nitrous oxide, a potent greenhouse gas, and enabling the plants to use nitrogen more efficiently.
  • New, high-yielding cultivars in Afghanistan, Egypt and Pakistan were developed using wild genes and have been released as they are more robust to the warming climate.

“Breeding the first beneficial interaction with the soil microbiome — in this case biological nitrification inhibition, or BNI-wheat — is a landmark achievement by CIMMYT and JIRCAS, opening up a whole new spectrum of opportunities to boost cropping systems’ resilience and reduce environmental footprints,” says Victor Kommerell, co-author of the GCB review, and Director of CropSustaiN, a new research initiative to determine the global climate mitigation and food security potential of BNI wheat.

The second study in Nature Climate Change* showcases the urgent need to scale-up exploration and use of genetic diversity for improved climate resilience. Among the traits needed are deeper, more extensive root systems for better water and nutrient access; photosynthesis that performs well across a wider temperature range; better heat tolerance in reproductive processes; and improved survival during delayed rains or temporary flooding.

“Tapping into the complex climate-resilient traits so urgently needed today requires both access to greater genetic diversity and a paradigm shift in breeding approaches,” explains co-author of the GCB review, Dr. Julie King of Nottingham University.

Modern crop breeding has focused on a relatively narrow pool of ‘star athletes’: elite crop varieties that are already high performers and that have known, predictable genetics. In contrast, the genetic diversity of wild wheat relatives offers complex climate-resilient traits — but their use has been more time-consuming, costly and riskier than traditional breeding approaches with elite varieties. Now, new technologies have changed that equation.

Making the impossible possible

“We have the tools to quickly explore genetic diversity that was previously inaccessible to breeders,” explains Dr. Benjamin Kilian, co-author of the review and coordinator of the Crop Trust’s Biodiversity for Opportunities, Livelihoods and Development (BOLD) project that supports conservation and use of crop diversity globally.

Among these tools are next-generation gene sequencing, big-data analytics, and remote sensing technologies, including satellite imagery. The latter allows researchers to routinely monitor traits like plant growth rate or disease resistance at unlimited numbers of sites globally.

However, realizing the full potential of these genetic resources will require global cooperation. “The most significant impacts will come through widespread sharing of genetic resources and technologies,” says Dr. Kilian.

New technologies allow crop researchers to precisely identify and transfer beneficial traits from wild relatives, making what has been seen as a risky, time-consuming process into a targeted, efficient strategy for climate-proofing crops. “Satellite technology turns the planet into a laboratory,” says Dr. Reynolds, “Combined with artificial intelligence to super-charge crop-breeding simulations, we can identify whole new solutions for climate resilience.”

This research, which also applies to any crop with surviving wild relatives, promises to enhance global food security and make cropping systems more environmentally sustainable. Developing more resilient and efficient wheat varieties will help feed a global population while reducing agriculture’s environmental footprint.

How Training Farmers to Produce Improved Seeds helps Mitigating Food Insecurity in the Conflict-Ridden Sudan

Written by dmedina on . Posted in Blogs.

Umm Zeina, a 40-year-old farmer living in El Nahal, in Sudan’s Gadarif State, was not happy with her yield, blaming the poor seeds and traditional techniques she was using. This was until she participated in the extensive seeds production training program organized by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).

“We learned a lot on how to produce seeds and how to control the parasite Striga mixed with crops. The training draws our attention to the fact that the availability of quality seed is the foundation for food production and productivity. As traditional farmers, we had very poor information about the availability, characteristics, and prices of seed of improved varieties,” Umm Zeina stressed.

ICRISAT’s extensive training attracted more than 350 (68 female) seed producer farmers from El Fashaga and El Nahal localities aimed at helping seed producers provide seeds of appropriate varieties for use by different categories of farmers. Farmers were also trained in better selection, treatment, and storage of seed from their own farms. The training also focused on the production of disease-free seeds to support agricultural productivity and success. The training helped to enhance farmers’ demand for improved seeds and eventually aimed to deliver improved seeds to more than 6000 farmers in El Fashaga, El Nahal and other neighboring localities.

This training was held as part of CIMMYT’s Sustainable Agrifood Systems Approach for Sudan (SASAS) program, which empowers farmers and herders to reduce the need for humanitarian assistance even in conflict-affected Sudan. In the context of the atrocious food crisis in Sudan, SASAS and partners work to ensure that farmers produce the quality seeds they need to enhance food production amid escalating conflict.

In El Fashaga and El Nahal localities, the seeds production training focused on sorghum, as this crop is widely adapted and drought tolerant as well as it is a staple crop to strengthen food security and contributes to agricultural diversity and economic growth in the regions where it is cultivated.

“During the training, we learnt a lot on how to choose the best seeds to produce improved seeds and how to choose the land, isolation area, and cleanliness to harvest. I was extremely interested to learn more about how to keep the seed to its purest form for replanting purposes and human or animal consumption,” said Tarig Hassan, a farmer living in El Nahal locality.

The seeds production training also aimed at maintaining seeds quality control through training and regulatory systems, and how to multiply and distribute seeds in a timely manner and at a price affordable for farmers. Farmers also learnt to use a revolving seed mechanism to make available seeds for many new seed producer farmers for the next season through farmer-to-farmer seeds distribution.

“The seed production training is not only on how to produce quality seeds and protect loss of seeds, but also about the use of diversified seeds of sorghum, millet and ground nut that serve for both food and nutrition security”, said Gizaw Desta, Senior Scientist in ICRISAT.

SASAS’s objective is to improve food security and access to income-generating opportunities through the adoption of sustainable agriculture practices and the promotion of agri-processing and post-harvest management. It focuses on supporting smallholder crop and livestock farmers to adapt their farming activities to climate change and abiotic pressures by diversifying their crops to further cushion themselves from climatic vagaries, reduce post-harvest loss, and improve market participation, and functionality. Women and youth are supported through training and agricultural and veterinary inputs to increase income generation activities and access to economic resources.

“At SASAS, we strive to train farmers in basic farm seed production. This helps preserve and expand the diversity of the seed on which our food systems in Sudan rely. Considering the dire food security situation in the country, we fully encourage farmers to be engaged in seeds production to provide different and improved seed varieties,” said Abdelrahman Kheir, SASAS Chief of Party in Sudan.

SASAS works with ICRISAT to uplift smallholder farmers and ensure food security in semi-arid tropics. SASAS partners are committed to elevating crop productivity, resilience, and sustainability vital to dryland communities’ prosperity. This steadfast commitment profoundly affects millions in the world’s most challenging agricultural regions.

Bridging research and policy: how CIMMYT’s science shapes practice in South Asia

Written by dmedina on . Posted in Blogs.

Science without policy is just academia; policy without science is just guesswork. Through a blend of robust field research and policy advocacy, CIMMYT aims to bridge the gap between policy and practice in promoting sustainable agricultural practices through crop diversification in South Asia.

Taking Bangladesh as an example, CIMMYT’s work in the country highlights the critical need to link research with policy to achieve sustainable agricultural practices, enhance food security, and improve farmer livelihoods.

The power of research-informed policy

Bangladesh’s agriculture is highly rice-centric; although rational, this is risky and arguably unsustainable. This means there needs to be a focus on crop diversification, which is one of the approaches toward sustainable agriculture that can address socioeconomic and environmental challenges.

Recognizing these challenges, CIMMYT has been at the forefront of developing solutions by conducting extensive multi-location on-site and on-farm trials that consider the socioeconomic and pedoclimatic dimensions of farm households.

Additionally, CIMMYT analyzes historical policies and initiatives that have been implemented by the Bangladeshi government and international partners to promote crop diversification. Several opportunities for improvement were identified in past policies and project implementation; addressing these challenges requires bridging the gap between policies and research to scale up crop diversification efforts.

Through the RUPANTAR and CGIAR Transforming Agrifood Systems in South Asia (TAFSSA) projects, CIMMYT-Bangladesh has developed an analytical tool to understand the political economy of crop diversification policies and practices. When applied to agriculture policy research, this tool can be tailored to any country and policy context in South Asia.

Problem-solving for sustainable farming

Our policy-specific research, such as “Decoding the reality: Crop diversification and policy in Bangladesh”, has identified areas where policy and practical changes can drive significant improvements.

For example, while the government recognizes crop diversification in its agriculture policies starting with the Fifth Five-Year Plan, substantial funding for crop diversification efforts was only recently allocated. Integration of crop diversification into the government’s annual funding systems is essential to mainstream crop diversification in agriculture.

Many crop diversification policies and projects primarily focus on production, neglecting market systems development for new crops. Similarly, research suggests insufficient attention is paid to cold storage and other infrastructure needed to support diversification.

Most initiatives appear to have been project-driven, resulting in short-lived action without long-lasting impact. Insufficient coordination and support from government agencies appears to have affected projects led by both governments and development partners.

Stakeholder engagement spreads awareness

Without translating research into policy, we leave innovation on the shelf. CIMMYT-Bangladesh disseminates research findings to policymakers through the country Priority Investment Plan for the crop sector at the Bangladesh Agricultural Research Council (BARC), and South Asian Association for Regional Cooperation (SAARC) member countries through regional consultation workshops on accelerating the transformation process for sustainable and nutrition-sensitive food systems.

Looking ahead, CIMMYT’s efforts in South Asia remain dedicated to bridging the gap between research and policy. Ongoing projects aim to generate robust evidence, advocate for informed policy decisions, and foster partnerships across sectors. By continuing to lead in this space, CIMMYT strives to contribute to a more resilient agrifood system for South Asia.

Wheat breeding strategies for increased climate resilience

Written by dmedina on . Posted in News.

Wheat breeding strategies for increased climate resilience

With the challenges of climate change already affecting plant breeding, especially warmer days and warmer nights, the time to future proof the world’s food supply is now. In order to make the best-informed changes, scientists at CIMMYT ran simulations mimicking five scenarios that might play out over the next 70+ years.

The researchers used 3,652 breeding line records from six global nurseries administered by the International Wheat Improvement Network, which is coordinated by CIMMYT, and involves hundreds of partners and testing sites worldwide. Researchers ran the data through five different climate change scenarios, ranging from stable to severe.

Along with colleagues from Henan Agricultural University, Zhengzhou, China, ICARDA, and the Chinese Academy of Agricultural Sciences, CIMMYT scientists published their research in Nature Climate Change.

The results showed that less than one-third of wheat varieties adapted well to the warming the planet has already seen in the last 10 years. As temperatures increased in the simulation, researchers found a clear connection between rising temperatures and lower stability for a variety. As the global wheat-growing area becomes warmer and experiences more frequent heatwaves, breeding programs have to look beyond just yield optimization.

“Stability is key for breeding programs and farmers,” said co-lead author Matthew Reynolds, CIMMYT distinguished scientist and head of wheat physiology. “Knowing that a specific variety works well in a specific environment and produces an expected amount of yield allows farmers better plan their crop futures.”

“We performed the analysis from different perspectives, so that climate effects and appropriate adjustment suggestions for current breeding models can be considered from climate change, gene selection and/or gene–environment interaction perspectives,” said co-lead author Wei Xiong, CIMMYT Senior Scientist and Agricultural System Modeler.

The paradox of breeding elite lines

Local and regional breeding programs, as well as targeted breeding by CIMMYT, contribute to gene pools that overlap for many key agronomic traits, which limit genetic diversity.

“It is an unintended consequence,” said Reynolds. “As conventional breeding focuses on crossing the best and elite material, such focus can actually reduce genetic diversity.”

This ‘paradox’ shows the need to increase genetic variability and environmental diversification in breeding programs that are developing higher-yielding climate-resilient cultivars. Breeding programs also need to target traits associated with improved adaptation to increased temperatures and tolerance to heatwaves, which requires multidisciplinary integration.

Looking to the past for answers

Over the past 10,000 years, the climate has been unusually stable, meaning modern, domesticated bread wheat has not been exposed to wide swings in temperature that are forecast for the next 100 years. Wild wheat relatives, like Triticeae, have had millions of years of experience in weathering changing climates.

CIMMYT has a pre-breeding program that examines wild wheat races and more exotic sources for climate resilience traits. When such traits are identified genetically, new breeding techniques such as gene editing can be employed and breeding models refined.

To activate these new techniques, several barriers need to be overcome, including more sharing of germplasm between countries and breeding teams, the use of faster breeding cycles where appropriate and improved understanding of genes that improve heat tolerance without a yield penalty.

With reduced climate resilience and slow cultivar development, the need to increase genetic variability for climate adaptation is urgent, particularly in developing countries, where warming rate is unprecedented, and breeding cycles tend to be longer than in developed countries.

“Faced with more climate variability, breeders need to revisit their breeding strategies to integrate genetic diversity that confers climate resilience without penalties to productivity,” said Reynolds.

CropSustaiN BNI Wheat Mission

Written by Julian Bañuelos-Uribe on . Posted in Uncategorized.

The Novo Nordisk Foundation and CIMMYT have launched the 4-year CropSustaiN initiative to determine the global potential of wheat that is significantly better at using nitrogen, thanks to Biological Nitrification Inhibition (BNI)—and to accelerate breeding and farmer access to BNI wheat varieties.

With a budget of US$ 21 million, CropSustaiN addresses the pressing challenges of nitrogen pollution and inefficient fertilizer use, which contribute to greenhouse gas (GHG) emissions and ecological degradation. Currently, no other seed or agronomic practice-based solution matches BNI crops’ mitigation impact potential. Growing BNI crops can complement other climate mitigation measures.

The challenge

Agriculture is at the heart of both food and nutrition security and environmental sustainability. The sector contributes ca. 10-12% of global GHG emissions, including 80% of the highly potent nitrous oxide (N2O) emissions. Fertilizer use contributes to such N losses, because plants take up about 50%, the remainder being lost. Wheat is the world’s largest ‘crop’ consumer of nitrogen-based fertilizer—a relatively nitrogen-inefficient cereal—at the same time providing affordable calories to billions of resource-poor people and ca. 20% of globally consumed protein. CropSustaiN targets this nexus of productivity and planetary boundary impact by verifying and thus de-risking the needed breeding, agronomic, and social innovations.

A solution: BNI-wheat

BNI is a natural ability of certain plant species to release metabolites from their roots into the soil. They influence the nitrogen-transforming activity of nitrifying bacteria, slowing down the conversion of ammonium to nitrate in the soil. This preserves soil ammonium levels for a longer time, providing plants with a more sustained source of available nitrogen and making them more nitrogen-use efficient (nitrogen plant use efficiency). As a result, BNI helps reduce the release of N2O gas emissions and nitrate leaching to the surrounding ecosystem.

A research breakthrough in 2021, led by the Japan International Research Center of Agricultural Sciences (JIRCAS) in collaboration with CIMMYT, demonstrated that the BNI trait can be transferred from a wheat wild relative to a modern wheat variety by conventional breeding. BNI wheat can be made available to farmers worldwide.

Growing BNI wheat could reduce nitrogen fertilizer usage by 15-20%, depending on regional farming conditions, without sacrificing yield or quality.

 

Incorporating BNI into additional crops would reduce usage further. Farmers can get the same yield with less external inputs.

Other BNI-crops

CropSustaiN will work on spring and winter wheats. Rice, maize, barley, and sorghum also have BNI potential. CropSustaiN will build the knowledge base and share with scientists working on other crops and agronomic approaches.

Objectives and outcomes

This high risk, high reward mission aims to:

  • Verify the global, on-farm potential of BNI-wheat through field trial research and breeding.
  • Build the partnerships and pathways to meet farmer demand for BNI-wheat seeds.
  • Work with stakeholders on policy change that enables BNI crops production and markets

Success will be measured by determining nitrogen pollution reduction levels under different soil nitrogen environments and management conditions on research stations, documenting crop performance and safety, breeding for BNI spring and winter wheats for a wide range of geographies, and gauging farmer needs, interest, and future demand.

A collaborative effort

CIMMYT is the lead implementer of Novo Nordisk Foundation’s mission funding. CropSustaiN’s interdisciplinary, intersectoral, systems approach relies on building partnerships and knowledge-sharing within and outside this research initiative. 45+ partners are engaged in CropSustaiN.

The potential GHG emissions reduction from deploying BNI-wheat is estimated to be 0.016-0.19 gigatonnes of CO2-equivalent emissions per year, reducing 0.4-6% of total global N2O emissions annually, plus a lowering of nitrate pollution.

Impact on climate change mitigation and Nationally Determined Contributions (NDCs)

The assumption is that BNI wheat is grown in all major wheat-growing areas and that farmers will practice a behavioral shift towards lower fertilizer use and higher fertilizer use efficiency. That could lead to ca. a reduction of 17 megatons per year globally. This can help nations achieve their NDCs under the Paris Agreement.

International public goods, governance, and management

CIMMYT and the Foundation are committed to open access and the dissemination of seeds, research data, and results as international public goods. The governance and management model reinforces a commitment to equitable global access to CropSustaiN outputs, emphasized in partnership agreements and management of intellectual property.

Invitation to join the mission

The CropSustaiN initiative is a bold step towards agricultural transformation. You are invited to become a partner. You can contribute to the mission with advice, by sharing methods, research data and results, or becoming a co-founder.

Potential for independent performance information to shape farmers’ seed choice for hybrid maize: Insights from Kenya

Written by dmedina on . Posted in Blogs.

Maize production in Kenya is a critical component of the country’s agriculture and food security. However, climate change poses a serious threat to its production. Changes in temperature and precipitation patterns can affect maize growth, reduce yields, and increase the incidence of pests and diseases.

Prolonged droughts and unpredictable rainfall can lead to crop failures, while extreme weather events can damage crops and infrastructure. As the climate continues to change, it is essential for Kenyan farmers to adopt resilient agricultural practices and more adapted seed products to safeguard maize production and ensure food security for the population.

For decades, seed companies as well as governments and donors have invested in maize hybrid breeding. Dozens of new hybrids have been made available to seed companies throughout East Africa for multiplication and distribution. These hybrids are designed and tested to outperform older hybrids in terms of yield under rainfed conditions, to include tolerance to drought and pests.

However, the potential impact of these investments has been hampered by the slow turnover of hybrids among farmers. Research has shown that, despite the availability of newer, higher-performing varieties, farmers tend to purchase older, less productive hybrids. The ‘turnover problem’ in Kenya has been described by CIMMYT researchers in a recent publication.[1]

One of the constraints responsible for the low turnover of varieties is a lack of information among farmers on the performance of the newer products. Despite advancements in the development of new seeds and the retail infrastructure to reach farmers, neither the public nor the private sector is generating and disseminating information on the performance of different maize seed products across various agroecologies. Farmers therefore have choice overload but lack objective information on relative seed performance required to make informed seed choices across seasons and growing conditions.

CIMMYT conducted a field experiment to shed light on the potential influence of seed-product performance information on farmers’ seed choices. The study involved aggregating and packaging farmer reported yield data for some seed products and presenting this to randomly selected farmers at the point of sale to assess whether the new information would influence their choice of products. The study was conducted in Kirinyaga and Embu counties where, like many parts of Kenya, farmers have access to a diverse range of maize seed products from seed companies which promise benefits like higher yields and improved resilience but lack objective information on their performance which could support their choices, including when to switch and to what.

[1] https://journals.sagepub.com/doi/full/10.1177/0030727019900520

 

The experiment

The study was conducted in March 2024, at the onset of the long rain season. The research team collaborated with 36 local agro-dealers in five towns and surveyed over one thousand farmers.  Farmers were intercepted as they approached the agro-dealer outlets and briefed about the study. Upon consent, they were informed on the benefits of trying something new (experimenting with varieties) and  were offered a voucher for one free bag of maize seed to encourage them to try a seed product new to them. They then were randomly assigned to two experimental groups: treatment and comparison. Participants in the treatment group were shown a chart containing product-specific yield data on maize hybrids grown in their counties (see the chart below). The chart contained farmer-reported yields from the previous year’s long rain season aggregated at two levels: county average yield and the average yield of the top 25% of farmers who realized the highest yields. The latter demonstrated the actual potential of a seed product. They were asked that, if they wished, they could choose the voucher product for experimentation from the list but they were not required to. Participants in the comparison group were offered placebo information that would not affect their seed choice: they were given some fun facts about Kenya and agriculture in Kenya. We assess the effect of the information on the choice of the bag of seed they were buying with the voucher to experiment with.

Table 1: Product-specific performance information on maize seed products in Kirinyaga March-August 2023 *actual product names have been removed for this blog*

Before they made any purchases, the customers were asked about which maize seed they intended to buy. After purchase, they were interviewed again to find out which maize seeds they bought and how they had used the voucher.

 

 

 

 

 

 

What we found

Majority of the treatment farmers had a very positive evaluation of the information they received, indicating that they found it relevant and useful when making seed choice. Specifically, over 90% of them said that the information was trustworthy and easy to understand while about 80% said that the information was easy to recall. Over 80% of them disagreed that the list of varieties was too long to comprehend, the information on varieties was similar and hard to differentiate and that it was hard for them to choose a variety from the list.

This positive evaluation of the information is also reflected in their seed choices. Pre-purchases (before they entered the agrodealer store), farmers who were exposed to the performance information showed increased certainty in their choices and a higher inclination towards products listed in the product performance data, particularly the top-performing varieties. While 5% of the comparison farmers indicated that they did not know what to buy with their vouchers, only 2% of the treatment farmers suffered the same uncertainty. Such farmers relied mostly on agro-dealers to recommend a product they could experiment with.

As shown by the bar chat below, only 7% of comparison group farmers desired to use their vouchers on (or had an effective demand for) products which were the top two in the product performance lists. This increased to 27% among the information group farmers, representing an increase of 286% in the demand of top performing products.

However, although our intervention relaxed an essential constraint (product performance information) and increased the demand for some seed products, the actual purchases were subject to other constraints, stock-outs key among them. As a result, both groups showed shifts from initially desired products in their actual purchases. Even so, the treatment group maintained a stronger alignment with the listed products, exhibiting a higher likelihood of purchasing top-performing products. Only 5% of farmers in comparison group used their vouchers to purchase products which were top two in the product performance lists. This increased to 13% among farmers in the treatment group, representing a 160% increase in the likelihood of purchasing the best performing products in the lists.

Reflections

Slow varietal turnover among maize farmers in E. Africa is a pervasive problem and there is no one solution to it. This research shows that information on product performance can be an effective approach in bringing to the attention of farmers newer, more adapted and better yielding seed products. Dissemination of such information can be incorporated in extension programs, shared at the point of sale, shared through SMSs and WhatsApp messages, displayed in posters fixed in public places, etc.

The findings offer clear recommendations for future investments in seed systems development. These include the implementation of new product testing regimes to ensure quality and objectivity of performance data, testing what other information would be useful to farmers – beyond yield data, exploring new marketing options to reach farmers more effectively, and considering additional approaches to empower farmers with the knowledge they need to make informed decisions thus leading to improved agricultural productivity, resilience, and livelihoods.

Helping Colombia’s smallholder farmers to leverage and preserve maize diversity

Written by dmedina on . Posted in Blogs.

In Colombia, maize is the most important cereal, integral to culture, tradition, and diet. In 2019, Colombia consumed 7.2 million tons of maize, a quarter of which was white-grain maize used for human food (the remainder was yellow-grain maize for animal feed, with a small portion for industrial uses). National production is concentrated in the departments of Meta, Tolima, Córdoba, Huila, and Valle del Cauca. Native and creole maize varieties—the latter comprising farmer varieties of mixed native and other ancestries—are grown for use in traditional dishes or for sale at local markets.

Due to climate change, socioeconomic pressures, and the out-migration of smallholder farmers seeking better livelihoods, native maize varieties and the unique genetic qualities those varieties embody are endangered. We aim to design strategies that benefit smallholders who wish to continue in agriculture and perhaps continue growing native varieties valued in their communities, fostering the conservation and production of native maize. CIMMYT in Mexico has already facilitated commercial linkages between chefs in Mexico City and tourist areas (for example, in the states of Oaxaca, Yucatán, and the State of Mexico), sourcing blue maize landrace grain from farmers in mutually beneficial arrangements.

CIMMYT and local partners have launched an ambitious initiative to map and strengthen the value chain of native maize in the departments of Nariño, Cundinamarca, Boyacá, Valle del Cauca, and Putumayo to promote beneficial farmer-market linkages and better understand Colombia’s maize value chain. Carried out under the Nature Positive Initiative of OneCGIAR, the project is documenting maize conservation, marketing, and consumption to design a critical path that strengthens the value chain of Colombian native maize and benefits agriculture and the economy of rural Colombian communities.

Most native maize varieties in Colombia are grown on small plots for home consumption, exchange, and the sale of surplus grain. “The production is planned so that the percentage of sales is lower than consumption,” explains a farmer from Nariño. “Maize grain is sold in traditional markets, typically on Saturdays or Sundays, most often as fresh white and yellow corn.”

In such markets, farmers may also sell their grain to intermediaries, but only in the markets of Nariño is the sale of creole and native maize varieties acknowledged. Varieties include yellow Capia, white Capia, yellow Morocho, and Granizo, with Chulpe being less common. The grain purchased is used to prepare a variety of traditional dishes and beverages.

The most commonly grown varieties are intended for the market and probably the regional and urban cultural groups that consume them, such as in Guaitarilla, Nariño, where large crops of white maize are marketed through intermediaries and traders to satisfy demand.

“A variety that is not widely grown may become more prominent due to market changes—such as the rise of niche markets,” the research team notes. Good examples are the departments of Pasto, Nariño, and Cundinamarca, where maize is increasingly grown to meet demand from buyers of purple or colored maize.

We have already identified several possible niche markets for smallholder maize varieties:

  • Fair trade enterprises. They promote the commercialization of national products at fair prices for farmers, offering maize in various forms from regions such as Boyacá and Cundinamarca.
  • Restaurants. They use maize in traditional dishes, reinterpretations of Colombian cuisine, and culinary experiments.
  • Small-scale local intermediaries. Without a fixed physical space, they distribute products to end users and other businesses.

Significant challenges may hamper these and other possible market opportunities in the maize value chain. Farmers, for example, face high production costs, climate change losses, competition from neighboring countries, dependence on intermediaries for sales, and a lack of land. For their part, buyers struggle with obtaining consistent production volumes from farmers, lack storage infrastructure, and face postharvest pest and disease management challenges.

While they are compelled by the need to feed their families and, if possible, grow enough grain to sell for a profit, smallholder maize farmers have also expressed interest in preserving maize diversity and their cultural practices.

“We are not interested in growing monocultures for marketing; we grow maize out of love to continue preserving it,” comments a farmer from Nariño. Another farmer adds: “I would grow or sell more if the production were aimed at protecting agrobiodiversity, food security, sovereignty, and preserving cultural practices.”

To understand how niche markets could influence the conservation and rescue of native and creole maize in Colombia and, at the same time, design a critical path that strengthens the value chain and promotes fair and efficient niche markets, CIMMYT and its partners are conducting focus group interviews and buyer-meets-seller events. The aim is to mitigate challenges highlighted by the actors and create beneficial conditions for farmers and consumers, promoting a better future for Colombian smallholder farmers.

We deeply thank CIMMYT partners in Colombia for their contributions to this work: Andrea Gomez, Andrea Pinzón, and Jeisson Rodríguez.

Linking sustainable agricultural methods

Written by Julian Bañuelos-Uribe on . Posted in Publications.

While agricultural food systems feed the world, they also account for nearly a third of the world’s greenhouse gas (GHG) emissions. Reducing the negative environmental footprint of agrifood systems while at the same time maintaining or increasing yields is one of the most important endeavors in the world’s efforts to combat climate change.

One promising mechanism is carbon credits, a set of sustainable agricultural practices designed to enhance the soil’s ability to capture carbon and decrease the amount of GHG’s released into the atmosphere.

Farmers generate these carbon credits based on their reduction of carbon released and then sell these credits in the voluntary carbon market, addressing the critical concern of sustainably transforming agricultural systems without harming farmers’ livelihoods.

Two is better than one

Conservation Agriculture (CA) is a system that involves minimum soil disturbance, crop residue retention, and crop diversification, among other agricultural practices. Its potential to mitigate threats from climate change while increasing yields has made it increasingly popular.

Using remote sensing data and surveys with farmers in the Indian states of Bihar and Punjab, four CIMMYT researchers quantified the effect on farmer’s incomes by combining CA methods with carbon credits. Their findings were published in the April 22, 2024, issue of Scientific Reports.

Previous CIMMYT research has shown that implementing three CA practices: efficient fertilizer use, zero-tillage, and improved rice-water management could achieve more than 50% of India’s potential GHG reductions, amounting to 85.5 million tons of CO2.

“Successfully implemented carbon credit projects could reward farmers when they adopt and continue CA practices,” said Adeeth Cariappa, lead author and environmental and resource economist at CIMMYT. “This creates a win–win scenario for all stakeholders, including farmers, carbon credit businesses, corporate customers, the government, and the entire economy.”

Farmers would enjoy an additional income source, private sectors would engage in employment-generating activities, the government would realize cost savings, and economic growth would be stimulated through the demand generated by these activities.

Less carbon and more income

The researchers found by adopting CA practices in wheat production season, farmers can reduce GHG emissions by 1.23 and 1.97 tons of CO2 per hectare of land in Bihar and Punjab States, respectively.

The researchers determined that CA practices, when combined with carbon credits, could boost farmer income by US $18 per hectare in Bihar and US $30 per hectare in Punjab. In Punjab, however, there is a ban on burning agricultural residue, which reduces potential earnings from carbon markets to US $16 per hectare.

“More farmers engaging CA methods is an overall positive for the environment,” said Cariappa. “But convincing individual farmers can be a struggle. By showing them that carbon credits are another potential source of income, along with increased yields, the case for CA is that much stronger.”

While the potential benefits are significant, there are challenges to linking CA and carbon credits.

“To achieve these potential benefits, carbon credit prices must rise, and projects must be carefully planned, designed, monitored, and implemented,” said Cariappa. “This includes selecting the right interventions and project areas, engaging with farmers effectively, and ensuring robust monitoring and implementation mechanisms.”

Eight-year study in India by CGIAR and ICAR scientists suggests adoption of Conservation Agriculture can boost yields and manage an increasing carbon footprint

Written by Nima Chodon on . Posted in Publications.

Twenty-twenty four is set to become one of the hottest years on record. Warmer temperatures are destabilizing ecosystems, threatening human life, and weakening our food systems. On Earth Overshoot Day, CIMMYT calls for increased attention to the interplay between environmental health and efficient, abundant food production through sustainable practices.

Food systems are one of the top contributors to greenhouse gas (GHG) emissions, accounting for one-third of all human-caused GHG emissions. While contributing to climate change, food production is also sorely impacted by it, undermining agrarian livelihoods and the ability to feed an increasing global population. Extreme and unpredictable weather is causing economic hardship, food and nutrition insecurity, and use of environmentally harmful practices.

In the Western Indo-Gangetic Plains of India, rice and wheat are the dominant staple crops, grown yearly in rotations covering more than 13 million hectares. But conventional tillage-based methods have been unable to increase yields. Some of these traditional methods based on intensive tillage have harmed the soil, exhausted aquifers, and increased GHG emissions, without raising crop yields. CGIAR soil and climate scientists and agronomists have partnered to find solutions that help increase rice and wheat production, while minimizing harmful environmental effects.

At CIMMYT, we interviewed a group of CGIAR scientists who recently published a long-term study on sustainable intensification in the Western Indo-Gangetic Plains. Their work, conducted at the Central Soil and Salinity Research Institute (ICAR-CSSRI) in Karnal, India, demonstrates how integrating Conservation Agriculture (CA)-based principles into cropping systems can support climate-resilient and sustainable food systems.

“Today, agriculture faces many challenges, such as increasing input costs to maintain yield in the face of climate change and ensuring the sustainability of agricultural land,” said Mahesh Gathala, senior scientist at CIMMYT.

He mentioned that the collaborative research spanned over eight years, covering various crops and cropping cycles, and studying seven scenarios representing different farming practices. One scenario was based on farmers’ existing practices, while the other six involved combining and integrating the agronomic management practices and crop diversification options based on CA principles. The team collected data on yield, profitability, soil health, global warming potential, and fertilizer use, to name critical factors.

Gathala highlighted, “The findings are consistent with our previous research conclusions, while reinforcing the significant compounding impact of Conservation Agriculture-based cropping practices in the region, in the long-run.”

According to M.L. Jat, a former CIMMYT scientist who is global director for ICRISAT’s Resilient Farm and Food Systems Program, the CA-based measures that emerged from this research are applicable in much of the Western Indo-Gangetic Plains and beyond.

“Most of our research trials over some 2-5 years have provided substantial evidence in favor of Conservation Agriculture-based cropping diversification and sustainable intensification,” Jat said. “However, this study is one of very few long-term, collaborative research trials that provide strong evidence for policy decisions on resilient, climate-smart cropping system optimization to boost yields and nutrition, while improving soil health and fighting climate change.”

Other lead authors of the publication, Timothy Krupnik, principal scientist at CIMMYT and CGIAR South Asia, and Tek Sapkota, the Climate Change Science lead at CIMMYT, provided further explanation of important lessons from this eight-year study.

How does CA contribute to the sustainable and conscious use of natural resources? In what ways could CA be framed to governments to develop policies that do a better job of feeding us nutritious food while contributing to climate change adaptation and mitigation?

Tek Sapkota: Conservation Agriculture promotes the production of nutritious, diversified crops, sustainable yield improvements, climate change adaptation, economic benefits, and environmental protection. Governments can support these initiatives through financial incentives, subsidies, investment in research and extension services, and the development of supporting infrastructure and market access. This support further enables farmers to implement and benefit from sustainable agricultural practices.

CIMMYT and CGIAR-led projects in South Asia, like CSISA/SRFSI/TAFFSA, have already recorded some wins for CA implementation. What are some immediate implications of this study on CIMMYT’s ability to deliver this knowledge to more smallholders in the region?

Timothy Krupnik: The ICAR-CIMMYT partnership establishes long-term experiments, or living labs, across diverse ecologies to build trust among smallholder farmers, extension workers, and stakeholders. These initiatives aim to demonstrate CA’s benefits, as part of sustainable intensification. The science-based evidence generated will be co-owned by partners, through their extension networks, and shared with farm communities to highlight CA’s advantages. Additionally, the study supports reducing carbon footprints, contributing to climate change mitigation and sustainable agricultural practices and potentially used by carbon market players to disseminate CA.

Apart from climate resilience, could you explain what are the economic benefits of diversification in the rice-wheat dominant systems?

Tek Sapkota: Diversifying away from rice-wheat cropping systems provides significant economic benefits beyond climate resilience. It enhances income stability, improves resource use efficiency, maintains soil health, reduces production costs (such as irrigation expenses and water usage), and opens up new market opportunities. Diversification contributes to the creation of more sustainable and profitable farming systems.

How can CGIAR and national agricultural research and extension systems promote more widespread adoption of these technologies by farmers in South Asia and beyond?

Tek Sapkota: By establishing a multi-stakeholder platform for learning, knowledge sharing, and developing adoption pathways, CGIAR Research Centers could work together with national partners to create programs that support capacity building and knowledge transfer. Another crucial step would be to collaboratively adapt and customize the technology to local production conditions ensuring smooth implementation at the grassroots level. Additionally, it is important to encourage innovations in policies, markets, institutions and financial mechanisms to facilitate scaling.

Sowing seeds of change to champion Conservation Agriculture

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

Florence Mutize’s thriving fields of maize, in Bindura, a small town in Mashonaland Central region of Zimbabwe, serve as living proof of the successes of Conservation Agriculture (CA), a sustainable cropping system that helps reverse soil degradation, augment soil health, increase crop yields, and reduce labor requirements while helping farmers adapt to climate change. The seeds of her hard work are paying off, empowering her family through education and ensuring that a nutritious meal is always within reach.

“I have been dedicated to these CA trials since 2004, starting on a small plot,” said Mutize. “Now, with years of experience and adaptation to changing climates, I’ve seen my yields increase significantly, harvesting up to a tonne of maize on a 30 by 30m plot using direct seeding and ripping techniques together with crop residue to cover the soil and rotating maize with soybean.”

Mutize is one of many mother trial host farmers implementing CA principles through the CGIAR Ukama Ustawi regional initiative in Bindura. A mother trial is a research approach involving testing and validating a suite of climate-smart agriculture technologies to identify the best-performing ones which can then be adopted on a larger scale.

Nestled in the Mazowe valley, Bindura experiences a subtropical climate characterized by hot, dry summers and mild, wet winters, ideal for agricultural production. But the extremes of the changing climate, like imminent dry spells and El Niño-induced threats, are endangering local farmers. Yet, smallholder farmers like Mutize have weathered the extremes and continued conducting mother trials, supported by the agriculture extension officers of the Agricultural and Rural Development Advisory Services (ARDAS) Department of the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development.

“Where I once harvested only five bags of maize, rotating maize with soybeans now yields 40 bags of maize and 10 bags of soybeans,” Mutize proudly shares.

The UU-supported CA program also extends to farmers in Shamva, like Elphas Chinyanga, another mother trial implementer since 2004.

“From experimenting with various fertilization methods to introducing mechanized options like ripping and direct seeding, these trials have continuously evolved,” said Chinyanga. “Learning from past experiences, we have gotten much more benefits and we have incorporated these practices into other fields beyond the trial area. I am leaving this legacy to my children to follow through and reap the rewards.”

Learning has been a crucial element in the dissemination of CA technologies, with CIMMYT implementing refresher training together with ARDAS officers to ensure that farmers continue to learn CA principles. As learning is a progressive cycle, it is important to package knowledge in a way that fits into current training and capacity development processes.

This process could also be labelled as “scaling deep” as it encourages farmers to move away from conventional agriculture technologies. Reciprocally, scientists have been learning from the experiences of farmers on the ground to understand what works and what needs improvement.

Inspired by the successes of his peers in Shamva, Hendrixious Zvomarima joined the program as a host farmer and saw a significant increase in yields and efficiency on his land.

“For three years, I have devoted time to learn and practice what other farmers like Elphas Chinyanga were practicing. It has been 14 years since joining, and this has been the best decision I have made as it has improved my yields while boosting my family’s food basket,” said Zvomarima.

The longevity and success of the initiative can be attributed to committed farmers like Mutize, Chinyanga, and Zvomarima, who have been part of the program since 2004 and are still executing the trials. Farmer commitment, progressive learning, and cultivating team spirit have been the success factors in implementing these trials. CIMMYT’s long-term advocacy and learning from the farmers has been key to a more sustainable, resilient, and empowered farming community.

Enhancing the resilience of our farmers and our food systems: global collaboration at DialogueNEXT

Written by Mike Listman on . Posted in Features.

“Achieving food security by mid-century means producing at least 50 percent more food,” said U.S. Special Envoy for Global Food Security, Cary Fowler, citing a world population expected to reach 9.8 billion and suffering the dire effects of violent conflicts, rising heat, increased migration, and dramatic reductions in land and water resources and biodiversity. “Food systems need to be more sustainable, nutritious, and equitable.”

CIMMYT’s 2030 Strategy aims to build a diverse coalition of partners to lead the sustainable transformation of agrifood systems. This approach addresses factors influencing global development, plant health, food production, and the environment. At DialogueNEXT, CIMMYT and its network of partners showcased successful examples and promising directions for bolstering agricultural science and food security, focusing on poverty reduction, nutrition, and practical solutions for farmers.

Without healthy crops or soils, there is no food

CIMMYT’s MasAgro program in Mexico has enhanced farmer resilience by introducing high-yielding crop varieties, novel agricultural practices, and income-generation activities. Mexican farmer Diodora Petra Castillo Fajas shared how CIMMYT interventions have benefitted her family. “Our ancestors taught us to burn the stover, degrading our soils. CIMMYT introduced Conservation Agriculture, which maintains the stover and traps more humidity in the soil, yielding more crops with better nutritional properties,” she explained.

CIMMYT and African partners, in conjunction with USAID’s Feed the Future, have begun applying the MasAgro [1] model in sub-Saharan Africa through the Feed the Future Accelerated Innovation Delivery Initiative (AID-I), where as much as 80 percent of cultivated soils are poor, little or no fertilizer is applied, rainfed maize is the most widespread crop, many households lack balanced diets, and erratic rainfall and high temperatures require different approaches to agriculture and food systems.

The Food and Agriculture Organization of the United Nations (FAO) and CIMMYT are partnering to carry out the Vision for Adapted Crops and Soils (VACS) movement in Africa and Central America. This essential movement for transforming food systems endorsed by the G7 focuses on crop improvement and soil health. VACS will invest in improving and spreading 60 indigenous “opportunity” crops—such as sorghum, millet, groundnut, pigeon pea, and yams, many of which have been grown primarily by women—to enrich soils and human diets together with the VACS Implementers’ Group, Champions, and Communities of Practice.

The MasAgro methodology has been fundamental in shaping the Feed the Future Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, an effort between government agencies, private, and public partners, including CGIAR. AID-I provides farmers with greater access to markets and extension services for improved seeds and crop varieties. Access to these services reduces the risk to climate and socioeconomic shocks and improves food security, economic livelihoods, and overall community resilience and prosperity.

Healthy soils are critical for crop health, but crops must also contain the necessary genetic traits to withstand extreme weather, provide nourishment, and be marketable. CIMMYT holds the largest maize and wheat gene bank, supported by the Crop Trust, offering untapped genetic material to develop more resilient varieties from these main cereal grains and other indigenous crops. Through the development of hardier and more adaptable varieties, CIMMYT and its partners commit to implementing stronger delivery systems to get improved seeds for more farmers. This approach prioritizes biodiversity conservation and addresses major drivers of instability: extreme weather, poverty, and hunger.

Food systems must be inclusive to combat systemic inequities

Successful projects and movements such as MasAgro, VACS, and AID-I are transforming the agricultural landscape across the Global South. But the urgent response required to reduce inequities and the needed investment to produce more nutritious food with greater access to cutting-edge technologies demands inclusive policies and frameworks like CIMMYT’s 2030 Strategy.

“In Latin America and throughout the world, there is still a huge gap between the access of information and technology,” said Secretary of Agriculture and Livestock of Honduras, Laura Elena Suazo Torres. “Civil society and the public and private sectors cannot have a sustainable impact if they work opposite to each other.”

Ismahane Elouafi, CGIAR executive managing director, emphasized that agriculture does not face, “a lack of innovative science and technology, but we’re not connecting the dots.” CIMMYT offers a pathway to bring together a system of partners from various fields—agriculture, genetic resources, crop breeding, and social sciences, among others—to address the many interlinked issues affecting food systems, helping to bring agricultural innovations closer to farmers and various disciplines to solve world hunger.

While healthy soils and crops are key to improved harvests, ensuring safe and nutritious food production is critical to alleviating hunger and inequities in food access. CIMMYT engages with private sector stakeholders such as Bimbo, GRUMA, Ingredion, Syngenta, Grupo Trimex, PepsiCo, and Heineken, to mention a few, to “link science, technology, and producers,” and ensure strong food systems, from the soils to the air and water, to transform vital cereals into safe foods to consume, like fortified bread and tortillas.

Reduced digital gaps can facilitate knowledge-sharing to scale-out improved agricultural practices like intercropping. The Rockefeller Foundation and CIMMYT have “embraced the complexity of diversity,” as mentioned by Roy Steiner, senior vice-president, through investments in intercropping, a crop system that involves growing two or more crops simultaneously and increases yields, diversifies diets, and provides economic resilience. CIMMYT has championed these systems in Mexico, containing multiple indicators of success from MasAgro.

Today, CIMMYT collaborates with CGIAR and Total LandCare to train farmers in southern and eastern Africa on the intercrop system with maize and legumes i.e., cowpea, soybean, and jack bean. CIMMYT also works with WorldVeg, a non-profit organization dedicated to vegetable research and development, to promote intercropping in vegetable farming to ensure efficient and safe production and connect vegetable farmers to markets, giving them more sources for greater financial security.

Conflict aggravates inequities and instability. CIMMYT leads the Feed the Future Sustainable Agrifood Systems Approach for Sudan (SASAS) which aims to deliver latest knowledge and technology to small scale producers to increase agricultural productivity, strengthen local and regional value chains, and enhance community resilience in war-torn countries like Sudan. CIMMYT has developed a strong partnership funded by USAID with ADRA, CIP, CRS, ICRISAT, IFDC, IFPRI, ILRI, Mercy Corps, Near East Foundation, Samaritan’s Purse, Syngenta Foundation, VSF, and WorldVeg, to devise solutions for Sudanese farmers. SASAS has already unlocked the potential of several well-suited vegetables and fruits like potatoes, okra, and tomatoes. These crops not only offer promising yields through improved seeds, but they encourage agricultural cooperatives, which promote income-generation activities, gender-inclusive practices, and greater access to diverse foods that bolster family nutrition. SASAS also champions livestock health providing food producers with additional sources of economic resilience.

National governments play a critical role in ensuring that vulnerable populations are included in global approaches to strengthen food systems. Mexico’s Secretary of Agriculture, Victor Villalobos, shared examples of how government intervention and political will through people-centered policies provides greater direct investment to agriculture and reduces poverty, increasing shared prosperity and peace. “Advances must help to reduce gaps in development.” Greater access to improved agricultural practices and digital innovation maintains the field relevant for farmers and safeguards food security for society at large. Apart from Mexico, key government representatives from Bangladesh, Brazil, Honduras, India, and Vietnam reaffirmed their commitment to CIMMYT’s work.

Alice Ruhweza, senior director at the World Wildlife Fund for Nature, and Maria Emilia Macor, an Argentinian farmer, agreed that food systems must adopt a holistic approach. Ruhweza called it, “The great food puzzle, which means that one size does not fit all. We must integrate education and infrastructure into strengthening food systems and development.” Macor added, “The field must be strengthened to include everyone. We all contribute to producing more food.”

Generating solutions, together

In his closing address, which took place on World Population Day 2024, CIMMYT Director General Bram Govaerts thanked the World Food Prize for holding DialogueNEXT in Mexico and stressed the need for all partners to evolve, while aligning capabilities. “We have already passed several tipping points and emergency measures are needed to avert a global catastrophe,” he said. “Agrifood systems must adapt, and science has to generate solutions.”

Through its network of research centers, governments, private food producers, universities, and farmers, CIMMYT uses a multidisciplinary approach to ensure healthier crops, safe and nutritious food, and the dissemination of essential innovations for farmers. “CIMMYT cannot achieve these goals alone. We believe that successful cooperation is guided by facts and data and rooted in shared values, long-term commitment, and collective action. CIMMYT’s 2030 Strategy goes beyond transactional partnership and aims to build better partnerships through deeper and more impactful relationships. I invite you to partner with us to expand this collective effort together,” concluded Govaerts.

[1] Leveraging CIMMYT leadership, science, and partnerships and the funding and research capacity of Mexico’s Agriculture Ministry (SADER) during 2010-21, the program known as “MasAgro” helped over 300,000 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.
