Working with smallholders to understand their needs and build on their knowledge, CIMMYT brings the right seeds and inputs to local markets, raises awareness of more productive cropping practices, and works to bring local mechanization and irrigation services based on conservation agriculture practices. CIMMYT helps scale up farmers’ own innovations, and embraces remote sensing, mobile phones and other information technology. These interventions are gender-inclusive, to ensure equitable impacts for all.
In 2018, CIMMYT continued to innovate and forge strategic alliances to combat malnutrition, tackle the effects of climate change and respond to emerging threats.
Building on the release of a new wheat genome reference map, our researchers more precisely tagged genes for valuable traits, including disease resistance, heat tolerance, and grain quality, in more than 40,000 CIMMYT wheat lines.
In collaboration with our partners, CIMMYT released 81 maize and 48 wheat varieties. More than 40,000 farmers, scientists and technical workers across the world took part in over 1,500 training and capacity development activities. CIMMYT researchers published 338 journal articles.
As the maize-hungry fall armyworm spreads from Africa to Southeast Asia, CIMMYT joined with more than 40 partners in an international consortium to advance research against the devastating insect pest.
CIMMYT used a scaling approach to extend the benefits of crop research to more farmers and consumers in developing countries in transformative and lasting ways. Smallholder farmers in Mexico, Pakistan and Zimbabwe are benefitting from the use of appropriate machinery and implements for efficient and climate-smart agriculture. A manual developed with the Food and Agriculture Organization (FAO) of the United Nations offers technical and business advice for local entrepreneurs offering mechanized services, such as sowing or threshing, to smallholder farmers.
As part of taste tests in Ethiopia, Kenya, and Tanzania, consumers indicated their willingness to pay a premium for quality protein maize (QPM), which contains enhanced levels of the amino acids needed to synthesize protein.
A CIMMYT-led study on gender has explored the lives and viewpoints of 7,500 men and women from farming communities in 26 countries, providing invaluable information that will lead to better productivity and food security.
2018 showed us that the passion and values of staff and partners help CIMMYT to have major impact on the livelihoods of smallholders and the poor. This Annual Report pays tribute to them.

A new study from researchers at the International Maize and Wheat Improvement Center (CIMMYT) shows that remote sensing can speed up and improve the effectiveness of disease assessment in experimental maize plots, a process known as phenotyping.
The study constitutes the first time that unmanned aerial vehicles (UAVs, commonly known as drones) with cameras that capture non-visible electromagnetic radiation were used to assess tar spot complex on maize.
The interdisciplinary team found among other things that potential yield losses under heavy tar spot complex infections could reach 58% — more than 10% greater than reported in previous studies.

“Plant disease resistance assessment in the field is becoming difficult because breeders’ trials are larger, are conducted at multiple locations, and there is a lack of personnel trained to evaluate diseases,” said Francelino Rodrigues, CIMMYT precision agriculture specialist and co-lead author of the study. “In addition, disease scoring based on visual assessments can vary from person to person.”
A major foliar disease that affects maize throughout Latin America, tar spot complex results from the interaction of two species of fungus that thrive in warm, humid conditions. The disease causes telltale black spots on infected plants, killing leaves, weakening the plant, and impairing ear development.
Phenotyping has traditionally involved breeders walking through crop plots and visually assessing each plant, a labor-intensive and time-consuming process. As remote sensing technologies become more accessible and affordable, scientists are applying them more often to assess experimental plants for desired agronomic or physical traits, according to Rodrigues, who said they can facilitate accurate, high-throughput phenotyping for resistance to foliar diseases in maize and help reduce the cost and time of developing improved maize germplasm.
“To phenotype maize for resistance to foliar diseases, highly trained personnel must spend hours in the field to complete visual crop evaluations, which requires substantial time and resources and may result in biased or inaccurate results between surveyors,” said Rodrigues. “The use of UAVs to gather multispectral and thermal images allows researchers to cut down the time and expenses of evaluations, and perhaps in the future it could also improve accuracy.”
Color-infrared image of maize hybrids in the experimental trials under fungicide treatment (A1) and non-fungicide treatment (A2) of tar spot complex of maize. Image data were extracted from two polygons from the two central rows in each plot (B).
Technology sheds new light on phenotyping
Receptors in the human eye detect a limited range of wavelengths in the electromagnetic spectrum — the area we call visible light — consisting of three bands that our eyes perceive as red, green and blue. The colors we see are the combination of the three bands of visible light that an object reflects.
Remote sensing takes advantage of how the surface of a leaf differentially absorbs, transmits and reflects light or other electromagnetic radiation, depending on its composition and condition. The reflectance of diseased plant tissue is different from that of healthy ones, provided the plants are not stressed by other factors, such as heat, drought or nutrient deficiencies.
In this study, researchers planted 25 tropical and subtropical maize hybrids of known agronomic performance and resistance to tar spot complex at CIMMYT’s experimental station in Agua Fría, central Mexico. They then carried out disease assessments by eye and gathered multispectral and thermal imagery of the plots.
This allowed them to compare remote sensing with traditional phenotyping methods. Calculations revealed a strong relationship between grain yield, canopy temperature, vegetation indices and the visual assessment.
Future applications
“The results of the study suggest that remote sensing could be used as an alternative method for assessment of disease resistance in large-scale maize trials,” said Rodrigues. “It could also be used to calculate potential losses due to tar spot complex.”
Accelerated breeding for agriculturally relevant crop traits is fundamental to the development of improved varieties that can face mounting global agricultural threats. It is likely that remote sensing technologies will have a critical role to play in overcoming these challenges.
“An important future area of research encompasses pre-symptomatic detection of diseases in maize,” explained Rodrigues. “If successful, such early detection would allow appropriate disease management interventions before the development of severe epidemics. Nevertheless, we still have a lot of work to do to fully integrate remote sensing into the breeding process and to transfer the technology into farmers’ fields.”
Funding for this research was provided by the CGIAR Research Program on Maize (MAIZE).
On May 15, 2019, as part of the CGIAR System Council meeting held at the ILRI campus in Addis Ababa, Ethiopia, around 200 Ethiopian and international research and development stakeholders convened for the CGIAR Agriculture Research for Development Knowledge Share Fair. This exhibition offered a rare opportunity to bring the country’s major development investors together to learn and exchange about how CGIAR investments in Ethiopia help farmers and food systems be more productive, sustainable, climate resilient, nutritious, and inclusive.
Under the title One CGIAR — greater than the sum of its parts — the event offered the opportunity to highlight close partnerships between CGIAR centers, the Ethiopian government and key partners including private companies, civil society organizations and funding partners. The fair was organized around the five global challenges from CGIAR’s business plan: planetary boundaries, sustaining food availability, promoting equality of opportunity, securing public health, and creating jobs and growth. CGIAR and its partners exhibited collaborative work documenting the successes and lessons in working through an integrated approach.
There were 36 displays in total, 5 of which were presented by CIMMYT team members. Below are the five posters presented.
How can the data revolution help deliver better agronomy to African smallholder farmers?
This sustainability display showed scalable approaches and tools to generate site-specific agronomic advice, developed through the Taking Maize Agronomy to Scale in Africa (TAMASA) project in Nigeria, Tanzania and Ethiopia.
Maize and wheat: Strategic crops to fill Ethiopia’s food basket
This poster describes how CGIAR works with Ethiopia’s research & development sector to support national food security priorities.
Addressing gender norms in Ethiopia’s wheat sector
Research shows that restrictive gender norms prevent women’s ability to innovate and become productive. This significantly impacts Ethiopia’s economy (over 1% GDP) and family welfare and food security.
Quality Protein Maize (QPM) for better nutrition in Ethiopia
With the financial support of the government of Canada, CIMMYT together with national partners tested and validated Quality Protein Maize as an alternative to protein intake among poor consumers.
Appropriate small-scale mechanization
The introduction of small-scale mechanization into the Ethiopian agriculture sector has the potential to create thousands of jobs in machinery service provision along the farming value chain.
About the CGIAR System Council
The CGIAR System Council is the strategic decision-making body of the CGIAR System that keeps under review the strategy, mission, impact and continued relevancy of the System as a whole. The Council meets face-to-face not less than twice per year and conducts business electronically between sessions. Additional meetings can be held if necessary.
In 2017, a call for proposals from Copernicus Climate Change Service Sectoral Information Systems led the International Maize and Wheat Improvement Center (CIMMYT to collaborate with Wageningen University, the European Space Agency (ESA), and other research and meteorological organizations to develop practical applications in agricultural and food security for satellite-sourced weather data.
The project, which recently ended, opened the door to a wide variety of potential uses for this highly detailed data.
ESA collects extremely granular data on weather, churned out at an hourly rate. CIMMYT researchers, including Foresight Specialist Gideon Kruseman, reviewed this data stream, which generates 22 variables of daily and sub-daily weather data at a 30-kilometerlevel of accuracy, and evaluated how it could help generate agriculture-specific weather and climate data sets.
“For most people, the reaction would be, ‘What do we do with this?’ Kruseman said. “For us, this is a gold mine.”
For example, wind speed — an important variable collected by ESA satellites — is key for analyzing plant evaporation rates, and thus their drought tolerance. In addition, to date, information is available on ideal ago-climatic zones for various crop varieties, but there is no data on the actual weather conditions during a particular growing season for most sites.
By incorporating the information from the data sets into field trial data, CIMMYT researchers can specifically analyze maize and wheat cropping systems on a larger scale and create crop models with higher precision, meaning that much more accurate information can be generated from the trials of different crop varieties.
The currently available historic daily and sub-daily data, dating back to 1979, will allow CIMMYT and its partners to conduct “genotype by environment (GxE)” interaction analysis in much higher detail. For example, it will allow researchers to detect side effects related to droughts and heat waves and the tolerance of maize and wheat lines to those stresses. This will help breeders create specific crop varieties for farmers in environments where the impact of climate change is predicted to be more apparent in the near future.
“The data from this project has great potential fix this gap in information so that farmers can eventually receive more targeted assistance,” said Kruseman.
These ideas are just the beginning of the agricultural research and food security potential of the ESA data. For example, Kruseman would like to link the data to household surveys to review the relationship between the weather farmers experience and the farming decisions they make.
By the end of 2019, the data will live on an open access, user-friendly database. Eventually, space agency-sourced weather data from as far back as 1951 to as recent as five days ago will be available to researchers and weather enthusiasts alike.
Already CIMMYT scientists are using this data to understand the potential of a promising wheat line, for seasonal forecasting, to analyze gene-bank accessions and for a statistical analysis of maize trials, with many more high-impact applications expected in the future.

Climate conditions in Nepal are suitable for the establishment of fall armyworm, which could cause considerable crop loss if not managed properly. The fall armyworm is a destructive pest that has a voracious appetite for maize and other crops. Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is working with the government of Nepal and other partners to address this imminent threat.
Chemical control of fall armyworm is too expensive and impractical for small-scale farmers, has negative human health effects, and can be a source of soil pollutants with a negative effect on biodiversity.
CIMMYT is currently evaluating the efficacy of push-pull cropping systems to control fall armyworm. Considered one of the most climate-smart technologies, push-pull systems use plant-pest ecology instead of harmful chemical insecticides to control weeds and insects. It is an environmentally friendly pest control method which is also economically viable for maize producers.

This system involves two types of crops: Napier grass (Pennisetum purpureum) and silverleaf desmodium legume (Desmodium uncinatum).
Desmodium plants are intercropped with the rows of maize and Napier grass surrounds the maize crop. Desmodium produces volatile chemicals that repel fall armyworm moths, while the Napier grass produces chemicals that attract female moths. The resulting push-pull system takes the pest away from the maize field.
An additional benefit is that desmodium improves nitrogen fertility through biological nitrogen fixation, which may reduce nitrogen input in the long-term. Desmodium also provides ground cover for maize, controlling soil erosion and offering protection from extreme heat conditions. Both desmodium and Napier grass are excellent fodder crops for livestock.
Because of all these reasons, push-pull technology is highly beneficial to smallholders who are dependent on locally available inputs for their subsistence farming. It can also have a positive spiral effect on the environment.
In November 2015, Jelle Van Loon set off for Zimbabwe, with a cross-section plan in his backpack. He spent two weeks working with a group of blacksmiths, searching Harare for parts and assembling machines in a bid to test whether the construction plans developed by his team were indeed designed to be built anywhere. “We might have had to change a few things, but three working machines were built, proving the accessibility of the construction plans and inherent replicability of the designs.”
From studying agronomic engineering and crop modelling in Belgium to working on supply chain issues in Peru, Jelle Van Loon amassed a range of experience before joining the International Maize and Wheat Improvement Center (CIMMYT) in 2012. Soon after joining, he began shaping up a team to work on mechanization issues.
“First and foremost I’m an agricultural engineer; I just happen to have a high affinity with mechanics,” he says. “I think my advantage is having a broad knowledge, being able to understand agronomy as well as mechanical engineering, and having studied agricultural economics in developing countries.”
This background has served him well in a role where a hands-on, multidisciplinary approach is crucial.
“Mechanization doesn’t necessarily mean building or creating more machines,” Van Loon explains, “but rather introducing technology and farm equipment to farmers to facilitate their work, as well as supporting them on how and when to use it to increase production efficiency.” Many people also assume that mechanization only involves motorized equipment such as tractors, he adds, when in fact any tool, even simple hand tools, which facilitate farmer work and alleviate drudgery fit into this concept.
CIMMYT’s mechanization team carries out research and development on a range of farm equipment. Team members draw and design prototypes, test them in the field and develop protocols for experiments. Combining agronomy and mechanics, they work to create machinery that supports farmers in their day-to-day work at each stage of the crop cycle: from land preparation, planting and fertilization, to harvest and shelling. They also support the generation of new business models which can deliver appropriate machinery to farmers working within resilient agri-food systems.
Welcome to the machine
One of the biggest challenges is changing the way farmers work. Many are resistant to investing in new machinery because they are unsure of how to use it, and simply cannot afford the risk of failure. As such, the team also places an emphasis on extension work. They have set up centers where growers can learn about the equipment and rent out some model machines. They also build the capacity of service providers through training on functional engineering for blacksmiths and manufacturers, and market intelligence for small sector entrepreneurs.
“It’s beyond just designing the machine. It’s really about taking products out to the field, seeing what works well and where, and then thinking about how we can get these products into the hands of farmers.”
Building on the work being carried out in Mexico, Van Loon is always looking at how other regions can also benefit from the mechanization unit and opportunities for collaborating with colleagues and partners in Africa and Asia. Equipment developed for farmers in Africa or Latin America could be adapted for use in South Asia or vice versa, but this requires a solid understanding of each region’s unique opportunities and challenges.
He points to the example of the two-wheel tractor engine, developed in China and popularized in Asia during the 1980s, when famine and the loss of draft animals prompted governments to subsidize that particular piece of equipment at the right time. The tractor is ubiquitous in countries such as Bangladesh, but it is unclear whether the same success is replicable in Africa and Latin America, neither of which has the same conditions, second-hand markets or import facilities. “We’re trying to learn from cross-regional efforts to scale up. Being able to understand different areas helps us find the weakest links and create more enabling environments,” Van Loon explains.
He and his team are continuously developing and evaluating new ideas, trialing ways of embedding mechatronics or sensory-based technology into their machines to help capture data and ease farmer workloads. Finding a way to keep these low-cost and convenient for farmer use may be a challenge, but positive testimonials from farmers keep him excited about the possibilities.
“I think it’s worthwhile to follow through on wild new ideas and see what happens because when it works out, the positive impact and change we help create is all that matters,” Van Loon notes.
“And more so, the cool thing about working in mechanization is we can go as far as our creativity lets us.”

Fall armyworm, a voracious pest now present in both Africa and Asia, has been predicted to cause up to $13 billion per year in crop losses in sub-Saharan Africa, threatening the livelihoods of millions of farmers throughout the region.
“In their haste to limit the damage caused by the pest, governments in affected regions may promote indiscriminate use of chemical pesticides,” say the authors of a recent study on fall armyworm management. “Aside from human health and environmental risks,” they explain, “these could undermine smallholder pest management strategies that depend largely on natural enemies.”
Agro-ecological approaches offer culturally appropriate, low-cost pest control strategies that can be easily integrated into existing efforts to improve smallholder incomes and resilience through sustainable intensification. Researchers suggest these should be promoted as a core component of integrated pest management programs in combination with crop breeding for pest resistance, classical biological control and selective use of safe pesticides.
However, the suitability of agro-ecological measures for reducing fall armyworm densities and impact must be carefully assessed across varied environmental and socioeconomic conditions before they can be proposed for wide-scale implementation.
To support this process, researchers at the International Maize and Wheat Improvement Center (CIMMYT) reviewed evidence for the efficacy of potential agro-ecological measures for controlling fall armyworm and other pests, consider the associated risks and draw attention to critical knowledge gaps. Findings from the Africa-wide study indicate that several measures can be adopted immediately, such as sustainable soil management, intercropping with appropriately selected companion plants and the diversification of farm environments through management of habitats at multiple spatial scales.

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.”

LUSAKA, Zambia (CIMMYT) – The CGIAR Research Program on Maize (MAIZE) officially announced the winners of the 2019 MAIZE Youth Innovators Awards – Africa at an awards ceremony held on May 9, 2019, in Lusaka, Zambia. These awards recognize the contributions of young women and men under 35 to innovation in African maize-based agri-food systems, including research for development, seed systems, agribusiness, and sustainable intensification. The awards, an initiative of MAIZE in collaboration with Young Professionals for Agricultural Research and Development (YPARD), were offered in three categories: farmer, change agent, and researcher.
The MAIZE Youth Innovators Awards aim to identify young innovators who can serve to inspire other young people to get involved in maize-based agri-food systems. This is the second year of the award, which was launched in 2018 with a first cohort of winners from Asia. Part of the vision is to create a global network of young innovators in maize based systems from around the world.
2019 award recipients were invited to attend the Stress Tolerant Maize for Africa (STMA) project meeting in Lusaka, May 7-9, where they had the opportunity to present their work. The project meeting and award ceremony also allowed these young innovators to network and exchange experiences with MAIZE researchers and partners. Looking forward, award recipients may also get the opportunity to collaborate with MAIZE and its partner scientists in Africa on implementing or furthering their innovations.

It uses artificial intelligence and machine learning to easily detect the pest across maize crops at any stage of the production cycle. The app aims to assist farmers, extension workers, and agribusinesses in democratic republic of Congo with early detection and accurate diagnosis. Through SMS and smart alert notifications, the Mobile Agribiz App provides farmers with constant reminders and real-time information on how to detect, manage, and address fall armyworm on maize.
Blessings Likagwa (Malawi) – Category: Farmer
Likagwa lives in Mtunthama, Malawi, where he works on his family’s farm. From a young age he has had an interest in farming and for the past eight years he has been involved in growing a variety of crops, especially maize and cassava. In the future he hopes to use his bachelor’s degree in Community Development and his interest in technology to help smallholder farmers in Malawi and Eastern Africa adapt to the challenges of climate change and rapid population growth. Since 2018, in collaboration with UNICEF and Kyoto University, he has investigated how drone technology can improve agricultural performance and benefit Malawi’s smallholders.
Ismael Mayanja (Uganda) – Category: Researcher
Mayanja is a 2019 graduate of Makerere University with a Bachelor of Science degree in Agricultural Engineering. He is currently assisting research at Makerere University to ascertain and quantify post-harvest losses associated with transportation of agricultural produce in the markets of Kampala district, Uganda. His primary research interest lies in post-harvest handling and technology, motivated by the reported 40% post-harvest loss of agricultural produce by farmers in sub-Saharan Africa. He developed a bicycle-powered maize cleaning machine to increase efficiency and reduce time dedicated to cleaning maize at several primary schools in Uganda.
Admire Shayanowako (Republic of South Africa) – Category: Researcher
Shayanowako is a researcher at the African Centre for Crop Improvement (ACCI) – University KwaZulu-Natal. His research focuses on the parasitic weed Striga, also known as witch weed, which causes severe crop losses to millions of small-scale African maize farmers. The goal of the project is to combine breeding for Striga resistance in maize with a soil fungus, Fusarium oxysporum f.sp. strigae (FOS) that is highly specific in its pathogenicity to Striga and acts as a biological control agent. The breeding approach aims to develop at least partial host resistance in open pollinated maize germplasms that are adapted to the semi-arid regions. When partial host resistance is augmented with biological control agent FOS, parasitic effects of Striga decline overwhelmingly. Currently, the breeding component of the research has embarked on identification of quantitative trait locus (QTL) controlling Striga resistance in maize through genomic based approaches.

A new fact sheet debunking myths about agricultural labor and mechanization has been presented at the Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) end of project review meeting in Harare, Zimbabwe.
The fact sheet, based on a recent study by the International Maize and Wheat Improvement Center (CIMMYT), shows African farming households are far more dependent on hire labor markets, and much more inclined to hire mechanization services, than previously assumed.
Over 50 agriculture for development specialists are gathering from May 11 to 17, 2019, to review the FACASI project’s progress. The project investigated how small-scale mechanization, such as two-wheel tractors with attachments, can be used to improve farm power balance, reduce labor drudgery, and promote sustainable intensification in Eastern and Southern Africa. The project also built the capacity of farmers to use size-appropriate machinery and trained hire service providers, to increase the equitable availability of mechanization services.
At the review meeting, participants will focus on widening the availability and use of small mechanization through commercialization, social inclusion, policy implications, and how to best use research outputs. They will also get to see two-wheel tractors in action and meet project farmers in visits to different districts around Zimbabwe.
In attendance are representatives from the project’s funder, the Australian Centre for International Agricultural Research (ACIAR), and partners including Ethiopia’s Ministry of Agriculture, the University of Zimbabwe, Zimbabwe’s Ministry of Lands Agriculture Water Climate and Rural Resettlement, the University of Southern Queensland, service providers and training centers from Zimbabwe, and private sector representatives from Zimbabwe and Ethiopia.
