In May, CIMMYT, in collaboration with the local government, organized an Agriculture Fair in Janaki Rural Municipality, Kailali district, Nepal, introducing farmers to modern farming techniques and machinery. The event inspired farmers like Ramfal Badayak, chairman of Biz Briddhi Krishak Cooperative, to adopt advanced tools, leading his cooperative to purchase two plant cultivators that now save time and labor for all members. With over 40 stalls and more than 4,000 daily visitors, the fair also benefited local suppliers by enabling direct sales to farmers, reducing costs by eliminating middlemen. This transformative event exemplified the potential of such platforms to modernize agriculture and support local communities.
CGIAR has launched a pilot program in Zimbabwe’s Mbire and Murehwa districts to promote agroecological solutions, with CIMMYT as a key partner. The initiative aims to develop sustainable farming practices by addressing challenges like pest outbreaks, drought, and access to quality seeds. CIMMYT’s involvement includes introducing innovative technologies such as demonstration plots and seed fairs, designed to enhance agricultural resilience and sustainability in the region. This collaborative effort seeks to empower local farmers and create a more sustainable agricultural system in Zimbabwe.
The Africa-China-CIMMYT Science Forum in Nairobi gathered experts from China and Africa to explore strategies for transforming agrifood systems through innovation and cooperation. Organized by CAAS and CIMMYT, the forum emphasized the importance of collaboration in addressing food security, rural poverty, and climate resilience in Africa. Key discussions focused on the benefits of technology transfer and research partnerships to support smallholder farmers and advance agricultural modernization across the continent.
CIMMYT participated in the Ukama Ustawi (UU) Share Fair in Zimbabwe, showcasing technologies like solar-powered irrigation and conservation agriculture. Emphasizing crop-livestock integration, gender-inclusive mechanization, and business models, CIMMYT aims to strengthen food system resilience and improve farmer livelihoods. Potential collaborations include youth engagement and alternative feed sources.
In Central and West Asia and North Africa (CWANA), agri-food systems are under pressure from resource depletion, population growth, and food insecurity. CIMMYT’s work is vital, focusing on sustainable agricultural practices and innovative technology to enhance productivity and resilience. Research and development efforts are critical in addressing the environmental and socio-economic challenges of agriculture in this diverse and dynamic region.
To combat food loss and waste, Sylvanus Odjo post-harvest specialist at CIMMYT and Heike Ostermann post-harvest expert at Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) argue for a comprehensive approach that goes beyond single solutions such as storage technologies.
Research for development organizations generate a wealth of knowledge. However, due to time and resource restraints, this knowledge has not been systematically analyzed, and the dynamics of how research is shared online have not been fully understood.
Today, technical advances in text mining, network analysis and hyperlink analysis have made it possible to capture conversations around research outcomes mentioned almost anywhere on the web. New digital research methodologies have emerged offering comprehensive approaches to leverage data across the web and to synthesize it in ways that would be impossible to carry out using traditional approaches.
In a study published in Nature Scientific Reports, scientists from the International Maize and Wheat Improvement Center (CIMMYT) teamed up with researchers from the University of Coimbra and University of Molise to investigate how CIMMYT research in climate change and climate sensitive agriculture is developing and the extent to which the center is exchanging knowledge with communities around the world.
Using text mining, social network analysis and hyperlink analysis to uncover trends, narratives and relationships in digital spaces such as research databases, institutional repositories, and Twitter, the team found that CIMMYT has steadily increased its focus on climate change research and is effectively sharing this knowledge around the world. The authors also found that CIMMYT’s climate research was centered on three main countries: Mexico, India, and Ethiopia.
The novel analytical framework developed by the team will help scientists track where their research is being shared and discussed on the web, from traditional scientific journal databases to social media.
“The web analytics framework proposed in this paper could be a useful tool for many research for development organizations to assess the extent of their knowledge production, dissemination, and influence from an integrated perspective that maps both the scientific landscape and public engagement,” said Bia Carneiro, first author of the paper.
The results of the study showed that sharing of CIMMYT’s climate science research was strongest on academic and research platforms but was also reflected in social media and government and international organization websites from across the Global North and South.
The findings from the study are important for the decolonization of science and the democratization of scientific debate. They show that CIMMYT is decolonizing climate science by sharing, creating, and co-creating knowledge with communities across the globe, particularly in Latin America, South Asia and Africa. On Twitter, the team noted that almost all countries were mentioned in CIMMYT’s Twitter conversations.
The study also shows that CIMMYT is bringing climate science and climate-sensitive agriculture into public debate, particularly through social media platforms, though they note there is potential to share more knowledge through these channels.
According to CIMMYT Agricultural Systems and Climate Change Scientist and coordinator of the study, Tek Sapkota, these types of analyses help research for development organizations to understand how people around the world view their expertise on subject matter, identify their comparative advantage and develop the value proposition of their work going forward.

The International Maize and Wheat Improvement Center (CIMMYT) Director General, Bram Govaerts, participated in a panel discussion on applied maize science to sustainably feed the world as part of the International Maize Congress on October 19-20, 2022 in Argentina.
The congress was organized by the governments of Córdoba and of the Central Region provinces of Argentina, together with the Argentine Maize and Sorghum Association (MAIZAR) and the Córdoba Grain Exchange.
Other panelists for the session included representatives from Argentina’s National Agricultural Technology Institute (INTA), the National Scientific and Technical Research Council (CONICET), and the National University of Mar del Plata.
In his presentation, Govaerts highlighted CIMMYT’s scientific efforts to improve the resilience of grain-based systems and produce sufficient, nutritious, and sustainable diets. He also shared CIMMYT’s determination to adopt a collaborative and future-proof approach to research, factoring in climate change to support effective decision-making processes for food producers and to meet demand for innovations and technologies.

Farmers, development practitioners and scientists gathered at Tropentag 2022 between September 14-16 to answer a question that will affect all our futures: can agroecological farming feed the world?
This year’s event explored the potential of agroecology to contribute to improved nutrition, enhanced natural resource management and farm incomes.
Sieg Snapp, Director of the Sustainable Agrifood Systems (SAS) program at the International Maize and Wheat Improvement Center (CIMMYT) presented on agroecology approaches to enhance learning in a changing world based on experiences with maize-based cropping systems in southern Africa. Snapp suggested that accelerated learning and adaptative capacity are key to the local generation of suitable solutions to agricultural problems, and proposed agroecology as a foundational approach that emphasizes understanding principles, harnessing biological processes, and enhancing local capacity.
Snapp shared how an agroecology living laboratory in Malawi has supported farmer agency around soil health, crop diversification and sustainable intensification since 2013, while living labs are being established in “food territories” in Zimbabwe to support innovation and strategies for evaluating the benefits of farm-scale agroecology approaches. She also explored solutions for pest management, inclusive financing modalities and collaborative innovation generation between farmers and researchers.
Gender and disease-resistant varieties
Michael Euler, Agricultural Resource Economist at CIMMYT, presented in the conference session on technology adoption and dissemination for smallholder farms, which included contributions on the adoption and impact of improved forage production, use of biogas facilities, agroecological management practices, improved wheat seeds, and access to and use genetic diversity in gene banks.
By using questionnaires that were addressed separately to male and female spouses in the household, researchers obtained insights on perceived individual roles in decision-making and agreements. The study found that an increase in the role of the female spouse in household farming decisions is positively associated with the uptake of rust-resistant varieties.
Additional sessions from the event focused on crops and cropping systems, animal production systems, food security and nutrition, agroecology, and food processing and quality.
Mobile phones are increasingly shaping the ways information is shared across industries, including in agriculture. The digitization of agricultural systems expedited by substantial efforts to narrow the digital divide and include smallholders means that data ownership and privacy issues are more relevant than ever.
The use of smartphone-based apps to improve accessibility to information for smallholder farmers has previously been under researched. In this publication, scientists from Ghent University and the International Maize and Wheat Improvement Center (CIMMYT) investigate incentives for smallholder farmers to use an agricultural advisory app in which data is shared using a designed discrete choice experiment.
Leveraging survey data from 392 farmers in Mexico, a conditional logit (CL) model was used to gain deeper insights into the preferences for attributes related to its usage. Groups and profiles were explored through a latent class (LC) model to investigate heterogeneity.
Farmers across ages were found to support the use of technology-based, site-specific extension services. The CL model results revealed farmers’ positive preference to receive support at first use and access to training, while they felt negatively towards sharing data with private actors. Meanwhile, the LC model demonstrates differences in preferences when farmers’ connectedness to the CIMMYT innovation hub and mastery approach goals variables are considered as a grouping variable. These variables also affect farmer preferences towards data sharing.
This study’s main contribution is in demonstrating the importance of nonfinancial incentives and influence of data sharing on farmer preferences. Through this improved understanding, the potential of technology in improving farmers’ welfare can be further realized.

In India, nearly one-sixth of groundwater reserves has been overexploited and almost one-fifth of them is either in critical or semi-critical condition. For a country that relies heavily on groundwater for drinking and irrigation, these statistics are close to a death sentence.
India’s water crisis, however, is not unique in the region. Population growth, coupled with increasing urbanization and industrialization, has made South Asia, one of the most heavily irrigated areas on earth, highly vulnerable to water stress. Moreover, as the effects of climate change are increasingly felt in those countries, agricultural production, even at the current level, may not be sustainable.
Against this background, ensuring that water resources are used efficiently and sustainably is key to meet the world’s growing demand. Over the last decades, traditional systems of irrigation have given way to more efficient drip irrigation systems that deliver the right amount of water and nutrients to the plant’s root zone. But as farm labor shortages become more severe, investing in automated irrigation systems — which promise increased production rates and product quality — will be the only way to ensure the sustainability of agricultural production systems worldwide.
A new article co-authored by a team of researchers from the International Maize and Wheat Improvement Center (CIMMYT) and the Thapar Institute of Engineering and Technology synthesizes the available information related to the automation of drip irrigation systems and explores recent advances in the science of wireless sensor networks (WSN), the internet of things (IoT) and other communication technologies that increase production capacity while reducing costs.
“Bundling both elements — drip irrigation and automation — in water application can lead to large savings in irrigation and boost water efficiency, especially in high water-consuming, cereal-based systems like the Indo-Gangetic Plains,” explained M.L. Jat, a principal scientist at CIMMYT and one of the authors of the review.
Investing in data and youth
Smart irrigation technologies, including sensors and the IoT, allow farmers to take informed decisions to improve the quality and quantity of their crops, providing them with site-specific data on factors like soil moisture, nutrient status, weed pressure or soil acidity.
However, this information is still limited to certain soil types and crops. “To upgrade drip irrigation systems elsewhere, especially in ‘water-stressed’ regions, we need additional agricultural background data in those areas,” Jat pointed out. “That’s the only way we can effectively customize innovations to each scenario, as one size does not fit all.”
Making this data available to and readable by farmers is also essential. Here, young people can become very good allies, as they tend to be more technologically savvy and used to working with large volumes of information. “Not only are they more skilled to integrate agricultural data into decision-making, but they can also help older farmers adopt and trust intelligent irrigation systems,” Jat concluded.

Incentives against subsidies
With increasing water shortages worldwide, making the most out of every drop becomes an urgent priority. But in countries where irrigation systems are highly subsidized, farmers may struggle to see this urgency. India, for instance, subsidizes the cost of energy to pump water for farming, thus encouraging smallholders to extract more than they need.
How do we incentivize farmers in these countries to embrace water-efficient technologies?
According to Jat, using the “scientific card” can work with smallholders who, after having farmed for decades, may not change their minds automatically. “These people may be reluctant to accept incentives for water-efficient mechanisms at first, but they will surely be interested in more scientific approaches,” Jat explained, stressing that “the emphasis must be on the science, not on the technology.”
Designing profitable business models can also incentivize producers to embrace more efficient mechanisms. Farmers who have enjoyed irrigation subsidies for decades may not see any profit in trying out new technologies — but what if they are given the chance to become champions or ambassadors of these agricultural innovations? “That brings in a whole new perspective,” Jat said.
Apart from incentivizing farmers, good business models can also draw the attention of large companies, which would bring investment to boost research and innovation in drip irrigation. “More and more businesses are getting interested in smart agriculture and low emission farming, and their inputs can help conceptualize the future of this field,” he observed.

Every year, the spores of the wheat blast fungus lie in wait on farms in South America, Bangladesh, and beyond. In most years, the pathogen has only a small impact on the countries’ wheat crops. But the disease spreads quickly, and when the conditions are right there’s a risk of a large outbreak — which can pose a serious threat to the food security and livelihood of farmers in a specific year.
To minimize this risk, an international partnership of researchers and organizations have created the wheat blast Early Warning System (EWS), a digital platform that notifies farmers and officials when weather conditions are ideal for the fungus to spread. The team, which began its work in Bangladesh, is now introducing the technology to Brazil — the country where wheat blast was originally discovered in 1985.
The International Maize and Wheat Improvement Center (CIMMYT), the Brazilian Agricultural Research Corporation (EMBRAPA), Brazil’s University of Passo Fundo (UPF) and others developed the tool with support from USAID under the Cereal Systems Initiative for South Asia (CSISA) project.
Although first developed with the help of Brazilian scientists for Bangladesh, the EWS has now come full circle and is endorsed and being used by agriculture workers in Brazil. The team hopes that the system will give farmers time to take preventative measures against the disease.
Outbreaks can massively reduce crop yields, if no preventative actions are taken.
“It can be very severe. It can cause a lot of damage,” says Maurício Fernandes, a plant epidemiologist with EMBRAPA.
Striking first
In order to expand into a full outbreak, wheat blast requires specific temperature and humidity conditions. So, Fernandes and his team developed a digital platform that runs weather data through an algorithm to determine the times and places in which outbreaks are likely to occur.
If the system sees a region is going to grow hot and humid enough for the fungus to thrive, it sends an automated message to the agriculture workers in the area. These messages — texts or emails — alert them to take preemptive measures against the disease.
More than 6,000 extension agents in Bangladesh have already signed up for disease early warnings.
In Brazil, Fernandes and his peers are connecting with farmer cooperatives. These groups, which count a majority of Brazilian farmers as members, can send weather data to help inform the EWS, and can spread alerts through their websites or in-house applications.
Wheat blast can attack a plant quickly, shriveling and deforming the grain in less than a week from the first symptoms. Advance warnings are essential to mitigate losses. The alerts sent out will recommend that farmers apply fungicide, which only works when applied before infection.
“If the pathogen has already affected the plant, the fungicides will have no effect,” Fernandes says.
A blast from the past
Because wheat had not previously been exposed to Magnaporthe oryzae, most wheat cultivars at the time had no natural resistance to Magnaporthe oryzae, according to Fernandes. Some newer varieties are moderately resistant to the disease, but the availability of sufficient seed for farmers remains limited.
The pathogen can spread through leftover infected seeds and crop residue. But its spores can also travel vast distances through the air.
If the fungus spreads and infects enough plants, it can wreak havoc over large areas. In the 1990s — shortly after its discovery — wheat blast impacted around three million hectares of wheat in South America. Back in 2016, the disease appeared in Bangladesh and South Asia for the first time, and the resulting outbreak covered around 15,000 hectares of land. CGIAR estimates that the disease has the potential to reduce the region’s wheat production by 85 million tons.
In Brazil, wheat blast outbreaks can have a marked impact on the country’s agricultural output. During a major outbreak in 2009, the disease affected as many as three million hectares of crops in South America. As such, the EWS is an invaluable tool to support food security and farmer livelihoods. Fernandes notes that affected regions can go multiple years between large outbreaks, but the threat remains.
“People forget about the disease, then you have an outbreak again,” he says.
Essential partnerships
The EWS has its roots in Brazil. In 2017 Fernandes and his peers published a piece of research proposing the model. After that, Tim Krupnik, a senior scientist and country representative with CIMMYT in Bangladesh, along with a group of researchers and organizations, launched a pilot project in Bangladesh.
There, agriculture extension officers received an automated email or text message when weather conditions were ideal for wheat blast to thrive and spread. The team used this proof of concept to bring it back to Brazil.
According to Krupnik, the Brazil platform is something of a “homecoming” for this work. He also notes that cooperation between the researchers, organizations and agriculture workers in Brazil and Bangladesh was instrumental in creating the system.
“From this, we’re able to have a partnership that I think will have a significant outcome in Brazil, from a relatively small investment in research supplied in Bangladesh. That shows you the power of partnerships and how solutions can be found to pressing agricultural problems through collaborative science, across continents,” he says.
Data has become a key driver of growth and change in today’s world.
There is growing recognition that data is indispensable for effective planning and decision-making in every sector. But the state of digital data in developing countries is far from satisfactory. In Asia, monitoring the Sustainable Development Goals (SDGs) remains a challenge due to a lack of accurate data.
Farmers in Coahuila are embracing technology by using WhatsApp to exchange experiences and access technical information, especially on sustainable farming practices such as ecological pest management.

The research team behind the MARPLE (Mobile And Real-time PLant disEase) diagnostic kit won the International Impact category of the Innovator of the Year 2019 Awards, sponsored by the United Kingdom’s Biotechnology and Biological Sciences Research Council (BBSRC).
The team — Diane Saunders of the John Innes Centre (JIC), Dave Hodson of the International Maize and Wheat Improvement Center (CIMMYT) and Tadessa Daba of the Ethiopian Institute for Agricultural Research (EIAR) — was presented with the award at an event at the London Science Museum on May 15, 2019. In the audience were leading figures from the worlds of investment, industry, government, charity and academia, including the U.K.’s Minister of State for Universities, Science, Research and Innovation, Chris Skidmore.
The BBSRC Innovator of the Year awards, now in their 11th year, recognize and support individuals or teams who have taken discoveries in bioscience and translated them to deliver impact. Reflecting the breadth of research that BBSRC supports, they are awarded in four categories of impact: commercial, societal, international and early career. Daba, Hodson and Saunders were among a select group of 12 finalists competing for the four prestigious awards. In addition to international recognition, they received £10,000 (about $13,000).
“I am delighted that this work has been recognized,” Hodson said. “Wheat rusts are a global threat to agriculture and to the livelihoods of farmers in developing countries such as Ethiopia. MARPLE diagnostics puts state-of-the-art, rapid diagnostic results in the hands of those best placed to respond: researchers on the ground, local government and farmers.”
On-the-ground diagnostics
The MARPLE diagnostic kit is the first operational system in the world using nanopore sequence technology for rapid diagnostics and surveillance of complex fungal pathogens in the field.
In its initial work in Ethiopia, the suitcase-sized field test kit has positioned the country — one of the region’s top wheat producers — as a world leader in pathogen diagnostics and forecasting. Generating results within 48 hours of field sampling, the kit represents a revolution in plant disease diagnostics. Its use will have far-reaching implications for how plant health threats are identified and tracked into the future.
MARPLE is designed to run at a field site without constant electricity and with the varying temperatures of the field.
“This means we can truly take the lab to the field,” explained Saunders. “Perhaps more importantly though, it means that smaller, less-resourced labs can drive their own research without having to rely on a handful of large, well-resourced labs and sophisticated expertise in different countries.”
In a recent interview with JIC, EIAR Director Tadessa Daba said, “we want to see this project being used on the ground, to show farmers and the nation this technology works.”

Development of the MARPLE diagnostic kit was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the CGIAR Platform for Big Data in Agriculture’s Inspire Challenge. Continued support is also provided by the BBSRC’s Excellence with Impact Award to the John Innes Centre and the Delivering Genetic Gain in Wheat project, led by Cornell University and funded by the UK’s Department for International Development (DFID) and the Bill & Melinda Gates Foundation.
