Her talk, titled âSustainable Agrifood Systems for a Changing World Requires Action-driven Science,” unveiled CIMMYTâs strategy for advancing the science of SAS in a rapidly changing world. In it, she addressed the pressing issues of climate change, conflict and food insecurity, emphasizing the need for action research, new data analytics and agro-diversity. These, she emphasized, are essential elements to safeguard the resilience and sustainability of our farming systems.
CIMMYT is happy to announce three new, improved tropical maize hybrids that are now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across southern Africa and similar agroecologies in other regions. NARES and seed companies are hereby invited to apply for licenses to pursue national release, scale-up seed production and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is January 26, 2024. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrids were identified through rigorous, years-long trialing and a stage-gate advancement process which culminated in the southern Africa Stage 5 On Farm Trials. The products were found to meet the stringent performance and farmer acceptance criteria for CIMMYTâs breeding pipelines that are designed to generate products tailored for smallholder farmers in stress-prone agroecologies of southern Africa.
To combat food loss and waste, Sylvanus Odjo post-harvest specialist at CIMMYT and Heike Ostermann post-harvest expert at Deutsche Gesellschaft fĂŒr Internationale Zusammenarbeit (GIZ) argue for a comprehensive approach that goes beyond single solutions such as storage technologies.

Snapp highlights the need for technology adoption and mentions the transformation of wheat value chains, particularly in reducing women’s labor through introducing machines and spare parts. She praises the commitment to balance input and output and cites an example of helping farmers during a fertilizer crisis.
CIMMYTâs new focus at play in Nepal
Timothy Krupnik, CIMMYT regional director for SAS, provided insights into the organization’s growth and global influence in over 80 countries. Krupnik highlighted CIMMYT’s transition from its primary focus on breeding and genomics to its engagement to include other factors, such as agronomy, on-farm participatory research, socioeconomic studies and comprehensive agrifood systems.
âThis shift in focus enhances CIMMYT’s understanding of the broader agricultural landscape and contributes to more comprehensive solutions,â said Krupnik. âRemarkable progress has been achieved in hybrid maize development and seed production, and we look forward to continuing to work with our Nepali partners.â
The meeting discussed various agricultural technology and innovation topics, including machinery, remote sensing, GIS toolsand greenhouse gas emission reduction strategies. NARC officials stressed the significance of enhancing capacity, especially in digital agriculture, to prepare Nepal for present and future climate challenges. Specific focus was on utilizing predictive crop modeling and simulation techniques to ensure crop resilience in the face of changing climate scenarios.
Drawing examples from her work and life, Louise Fresco, a recognized global leader in food and agriculture science, shared the need for diligence, commitment, understanding the bigger cause, and pushing boundaries for women to succeed in their careers. She is optimistic about the progress of women’s roles in fields such as food agriculture, science, and equity.Â
The eleventh speaker in the CIMMYT-hosted online seminar series ââŻCatalysts of Change: Women Leaders in Science â was Louise Fresco. Louise is a former UN director, an advocate for scientific research and innovation, a contributor to think tanks, and an advisor to academies in Europe and the United States.
CIMMYT Director General Bram Govaerts opened the session by introducing Louise as âa leader of change, a visionary, a renowned speaker, and thought leader.â Rahel Assefa, CIMMYT Regional Project ManagerâAfrica, moderated the session.
The ABCs of a Career
Louise recounted the beginnings of her career with the United Nations in Papua New Guinea, at a time when communication relied heavily on handwritten letters. Correspondence with her mother could take up to three months, and she often relied on a two-way radio for work-related communication. She recalled a particular incident when her radio was struck by lightning, leaving her without any means to connect with the outside world. âThe transformation brought about by technology since those days has motivated me to push forward, and there is still so much to accomplish,â she said.
Louise shared a few keywords that have helped her interpret the world around her and work toward greater goals. The first is assiduous. âWorking hard comes at a price. Balancing your private life and what you want to do at work is important and not easyâso ask for advice when needed. Donât be shy. Be diligent,â she said.
âSecond, think about the big picture,â she continued. âThink about where you want to go.â She also reminded the audience that having the big picture doesn’t mean being naive or believing everything will resolve by itself; rather, it implies knowing where one is standing and where one wants to go. She gave an example of how 20 years ago, genetic modification was a controversial subject and how she believed that âif we do the right science, even if nobody sees it, I will continue to talk about it and try to promote good work in this field.â
The third aspect is commitment. âCommitting to work and also to partners, because you can’t do it alone,â she told the audience, adding, âIn life, coincidence plays a roleâyou canât plan many things, but once there is an opportunity, donât be afraid to seize it.â
Women in the Workplace
Louise shared her experience working at the male-dominated Wageningen University, where she was the second woman to be appointed professor. She encountered various challenges but focused on collaborating with colleagues across different departments to establish her credibility. She summed up her approach: âBe brave. Be assiduous. Be committed. Find your partnerships. Donât be afraid to ask.â
When asked about the impact of being a woman in the workplace, Louise reflected, âThere were few women in our times, and that was an advantage and a disadvantageâadvantage because people would remember me, a disadvantage because they would always think I would serve the coffee and type up the minutes. The trick is to find the balance and not to get upset when people treat you like a secretary.â
âTimes are different today. You are lucky to live in a time when it is acceptable to be a woman in science, outreach, or agriculture, as you have the strength of numbers and supportive men who want to see qualified women making strides forward,â she added.
She recounted how, at FAO, she had 16 leadership positions reporting to herâand not one was a woman. She tried to recruit several women for the positions but faced challenges. âThe lesson learned is that we must focus on hiring and promoting women at all levels, not just in senior roles.â
Louise stressed the importance of fostering the right mindset from primary school onward. âBy the time students reach university, they should understand their potential roles regardless of gender, recognizing that there is no inherent difference in the capabilities of girls and boys. This approach can help cultivate a more inclusive and supportive environment.â
Travel Changes Worldview
Traveling plays a crucial role in personal development and cultural understanding, according to Louise. âGet out of your comfort zone. Go to countries where things are difficult.â
Drawing from her own experience, she recounted living in Africa for eight years without access to running water or electricity. âThis experience was enriching from a personal perspective, as it allowed me to understand what it is like to cook meals without electricity or gas. I realized how African women spend hours getting essentials such as water, firewood, and food,â she said. In Asia, she experienced the hardships of working in rice fields barefoot, exposing herself to parasitic diseases. âIt helped me understand how women bend over 10,000 times per hectare to plant rice seedlings.â These experiences have profoundly influenced her perspective, reinforcing the importance of the scientists and extension workers in bringing scientific knowledge to these communities to enhance their quality of life.
Continuous Learning for Women in Career
Louise emphasized the need for continuous learning to enhance personal growth. âTake note of things youâve noticed during the dayâthings youâve learned or seen around. Get a reflective diary,â she recommended, also encouraging reading and engaging in art forms. âRead about people different from youâother lives, other periods, other classes,â she said, sharing how she always reads books by authors of the place she is traveling to. Additionally, she highlighted that attending art events with colleagues can strengthen relationships, encourage discussions beyond work, and offer a unique perspective for women.
Role Models and Mentorship
Regarding mentorship, Louise pointed out that while she has never had a mentor herself, she actively advocates for mentorship opportunities for women. âYoung men also need mentors. We canât just emancipate women if we donât emancipate men too,â she said.
Louise explained how women can balance career growth with personal lifeâeither by specializing in a niche field and always being in demand, or by having children early on and then moving into a career full-fledged. She also suggested creating a network of women to help with childcare.
Louise concluded by sharing how she is extremely optimistic about the progress of women’s roles in food, agriculture, science, and equity. âI’m optimistic because so many women are so resilient and willing to work and discover things,â she said.

Nepal and CIMMYT have signed a 10-year collaboration to strengthen agriculture. The partnership, formalized by Secretary Govinda Prasad Sharma and CIMMYT director general Bram Govaerts, focuses on improving agricultural production and market systems in Nepal.
Ethiopia is the largest wheat producer in East Africa, with about 65% share of the total wheat production in sub-Saharan Africa. The area under wheat increased from about 1.5 million hectares in 2010 to 2.5 million hectares in 2023. More importantly, the productivity increased from 1.8 tons per hectare to about 3 tons per hectare in the same period, implying an increase of about 5% per annum in productivity (See Figure 1).
Several factors have contributed to this spectacular increase in productivity, including better farm practices implemented through clustering farmers land to reduce production costs, and introducing new, improved varieties which enable farmers to withstand challenges of crop diseases.
Figure 1: Wheat grain yield trends in Ethiopia by decade, 1960 to 2022 (USDA data).
A DNA finger printing study found that about 87% of the wheat area in Ethiopia comprises of varieties developed by the International Maize and Wheat Improvement Center (CIMMYT). In 2023, the Ethiopian Institute of Agricultural Research (EIAR) released six new wheat varieties of CIMMYT origin aimed for the mid to highlands (> 1800 meters above sea level) and lowlands (< 1800 masl) of the country. âThese newly released varieties provide options for farmers to face devastating rust diseases and at the same time obtain higher productivity,â said wheat breeder Leonardo Crespo.
Gadisa Alemu, wheat breeder based in EIAR, Kulumsa, added that the CIMMYT varieties were tested in farmersâ fields prior to release. âThis allows participating farmers to have quicker access to seed of selected varieties,â he said.
Wheat breeders . The aim was to obtain additional insights into the activities of CIMMYTâs partners and co-design a strategy that allows early evaluation and access to CIMMYT germplasm by national partners in Ethiopia. The team visited research centers in Holetta (highlands), Debre Zeit and, Kulumsa (midlands), and Arsi Negele (lowlands). Kulumsa, together with the highlands of Meraro and Asasa plains, represent about 60-70% of the wheat area in Ethiopia. Â âThese are important sites for wheat breeding activities in Ethiopia. Given that Holetta and Debre Zeit are hot spots for diseases, there is an increased interest in the Arsi Negele region to expand wheat production under irrigated conditions,â said Bekele Abeyo, wheat breeder and CIMMYTâs Ethiopia Country Representative.
AGG Maize and Wheat Improvement Teams Meet with Partners to Develop CG-NARES Breeding Strategy
In the first fortnight of September 2023, researchers from the International Maize and Wheat Improvement Center (CIMMYT) and National Agriculture Research and Extension System (NARES) met in Nairobi, Kenya to create high-level strategies and guiding principles for CG-NARES breeding activities. This is in alignment with the âGenetic Innovationsâ initiative of the One CGIAR strategy. CIMMYT representation included breeding teams from the wheat, maize, and dryland crops. The meetings were organized by Bill & Melinda Gates Foundation and CIMMYTâs Accelerating Genetic Gains in Maize and Wheat (AGG) project team.
It was recognized that the aforesaid strategies and principles need to be based on the biology of the crops and the context of each breeding program; incorporate the logistics of the breeding operations; and implement data driven tools for decision making such as genomic selection.
Participants shared how the application of novel and innovative technologies shortens the breeding cycles, accelerates the rate of genetic gain, and provides tools to enable the evaluation of plant materials (future variety candidates) and future target environments where these varieties will be grown.
It was concluded that effective breeding networks can be a strong instrument to enable faster delivery of improved germplasm to farmers. For this to happen efficiently, the networks require a high degree of coordination, organizational structure, governance, and clarity of roles. âIt is fundamental for network members to agree the objectives, vision and expected outcomes of collaborative activities. This forms the basis for co-design and co-implementation of crop improvement plansâ said Kevin Pixley, Interim Director of the Global Wheat Program and Director of the Dryland Crops Program.
The meeting also served as a platform for AGGâs and dryland cropâs breeding teams to exchange ideas and experiences. For instance, the Maize team shared their experience and learnings from on-farm-testing activities. The Wheat team shared the evolution and path of breeding modernization and implementation of new technologies. The Dryland Crops team shared their experience with co-designing and co-implementing breeding networks with NARES partners in Africa.
Global concerns are escalating as population growth, climate challenges and regional conflicts contribute to a food crisis. CIMMYT, in collaboration with 13 countries, is registering 160 drought-tolerant maize varieties to address changing climatic conditions, underscoring the need for unified efforts in global agricultural organizations.
On December 9, 2023, CIMMYT and the World Vegetable Center (WorldVeg) signed a memorandum of understanding (MoU) to further promote research and development, capacity strengthening activities and facilitate joint learning and the exchange of information and technology between the two organizations.
Sustainable diversification of food systems, good agricultural practices and safe and sustainable development of cereal and vegetable production systems and agrifood value chains sits at the core of this partnership.
The ultimate objective of the MoU is to further contribute to the achievement of the Sustainable Development Goals (SDGs), in particular SDG1 and SDG2, enhancing food and nutrition security, reducing rural and urban poverty and increasing employment opportunities in particular for women and youth.
CIMMYT and the World Vegetable Center are already partners in the Southern Africa Accelerated Innovation Delivery Initiative Rapid Delivery Hub (AID-I). Â Through this program, it is distributing seed kits directly to vulnerable populations such as pregnant and lactating mothers and children under five, as well as improving soil health, promoting the production of traditional African vegetables, and increasing employment opportunities through building vegetable businesses. Recent impacts in Zanzibar are a good example.

âThis collaboration between CIMMYT and WorldVeg is a testament to the potential of collective action, highlighting sustainable solutions and community empowerment as essential elements in combating malnutrition and enhancing overall well-being. We are building on the foundation already established by our collaborations within the Accelerated Innovation Delivery (AID-I) project in southern and eastern Africa,â said CIMMYT Director General, Bram Govaerts. âCIMMYT is excited to expand our connection with WorldVeg to bring innovations to even more people as crop diversification encourages improved nutrition.â
âThe World Vegetable Center is proud to deepen our work with CIMMYT. Reaching the Sustainable Development Goals will require not only advanced technologies but also systems to deliver those innovations to the people that need them most and this partnership will enable both priorities,â said Director General of the World Vegetable Center, Marco Wopereis. âPromoting and enhancing the availability of nutritious vegetables and cereals are vital to achieving these aims.â
By providing farmers with more options, CIMMYT and WorldVeg will promote the cultivation of diverse crops that are essential for a balanced and nutritious diet particularly among vulnerable communities around the world. By raising awareness about the significant benefits of incorporating different vegetables and cereals into daily diets, the partnership will inspire and encourage millions of people to fully embrace diversification and improved nutrition.

A recent meta-analysis by Leonard Rusinamhodzi a systems agronomist at CIMMYT and Sigrun Dahlin from the Swedish University of Agricultural Sciences provides an overview of how many agroecological practices are not widely adopted because of their high labor requirements.
Latest advances in sensor technology and data processing allow early detection, mapping and monitoring of crop infestation, helping prevent large-scale outbreaks.
A recent study published in Nature Scientific Reports, assesses the capability of very high-resolution satellite (VHRS) imagery and high-resolution unmanned aerial vehicles (UAVs) imagery for high-throughput phenotyping and detecting impacts of wheat rusts in earlier crop growth stages. UAVs and VHRS offer high potential for nonintrusive, extensive, rapid and flexible measurements of plant biophysical properties at very high spatial and temporal scales.
The studyâled by CIMMYT in partnership with the Ethiopian Institute of Agricultural Research (EIAR) and Lincoln Agritech Ltd from New Zealandâestablishes that these advanced sensor technologies are emerging as gamechangers in crop health management. They save time, complement traditional disease scoring methods and field surveys, and are cost-effective.
Further, the study establishes that multispectral VHRS sensors can pave the way for the upscaling of disease severity assessment from plot to regional scales at early growth stages.
Wheat rust is a global challenge
Globally, crop infections are an increasing threat to crop production and food security. Increased cross-border trade and travel, coupled with a changing climate are resulting in increased frequency and severity of crop disease outbreaks. Of all the diseases that affect wheat, wheat rusts are among the most damaging, capable of causing epidemics on a vast scale with significant economic and production losses. As of date, global losses from wheat rusts equate to 15 million tonnes per year (USD $2.9 billion). In Ethiopia, a major stripe/yellow-rust epidemic in 2010 affected an estimated 600,000 hectares, resulting in production losses of 15â20% and causing economic losses of USD $250 million. Similarly, a stem/black rust (SR) epidemic from 2013-2014 infected approximately 40,000 hectares. SR, which can cause 100% crop loss within weeks, is re-emerging as a major concern to wheat production.
Early detection, monitoring and timely intervention is key
Rapid early-season detection, monitoring and timely control of wheat rusts in susceptible varieties are critical to avoid large-scale outbreaks, especially in countries where fungicides are scarcely available or too costly for smallholders. UAV-based high-throughput phenotyping (HTP) has been recently investigated to support wheat improvement breeding, in particular, to assess plant growth development, canopy architecture, physiology, reaction to abiotic stress, crop disease and insect pest response, and wheat yield.
Figure 1
Spectral and thermal measurements at the plant and canopy levels allow for monitoring the interactions between plant germplasm and environmental (abiotic and biotic) factors. The current study identifies several spectral features from UAV and VHRS multispectral imagery that have strong assessment power for the detection of combined wheat rust diseases at early crop growth stages.
During a randomized trial conducted in Ethiopia, six bread wheat varieties with differing rust resistance were monitored using UAV and VHRS. In total, 18 spectral features were tested to assess stem and yellow rust disease progression and associated yield loss. Spectral properties of the wheat canopy (e.g., pigmentation, moisture, and biomass) are altered under rust disease stress. Using multispectral images and derived vegetation indices, it is possible to determine crop susceptibility to diseases and consequently can be used for detection and monitoring of wheat rusts.
Figure 2
Recent research on wheat, maize and dry bean demonstrated strong and significant correlations between vegetation indices extracted from UAV and VHRS imagery, confirming the feasibility of VHRS-HTP targeting biomass and yield; however, such satellite applications for plant breeding programs are still scarce.
Looking ahead to upscaling
This study provides valuable insight into the upscaling capability of multispectral sensors for disease detection from UAV imagery at 5Â cm per pixel to pan-sharpened satellite imagery at 50Â cm per pixel, demonstrating a first step towards upscaling disease detection from plot to regional scales. Further work will expand and improve current methodology to examine the VHRS detection capability towards machine and deep learning techniques (e.g., convolutional neural network) to allow for continuous monitoring systems, focusing on both single and mixed rust diseases under different treatments (e.g., variable fungicide rates, irrigation rates).
The early detection of diseases through spectral analysis and the integration of machine learning algorithms offers invaluable tools to mitigate the spread of infections and implement prompt disease management strategies.

On October 4, 2023, CIMMYT continued its online seminar series â Catalysts of Change: Women Leaders in Science. The event featured a talk by Esther Ngumbi, an entomologist and academic at the University of Illinois Urbana-Champaign.
A riverside farm
Born into a small, rural community on the Kenyan coast, Esther Ngumbi grew up farming alongside her family. âI enjoyed the process of growing crops because I knew at the end of the season, we would have extra food for ourselves,â she explained. By the age of seven she decided she wanted to go it alone, and her father provided a small strip of land by the river, where she took to growing vegetables.
âEvery morning I would sit there and just enjoy looking at this thriving cabbage patch I had,â she says. âAnd then one day the rains came. It rained for three days, the field flooded, and by the time the water receded I had lost my cabbages. The joy that had built was gone.â
âBut this heartbreak continued,â she added. âHalfway through the season I would watch all our hard work go to waste.â Along came insects, drought, or floodingâall the stresses associated with climate changeâand for her family it would mean no food. Ngumbi soon realized that this was not limited to her familyâs farm: her neighbors, community, county, and country were all impacted by these challenges, leading to widespread food insecurity.
Feeding curiosity
âAs a girl I was very curious,â said Ngumbi. âHow do these insect pests find our crops? And when they find them, why arenât our crops resilient enough to overcome these stresses? Little did I know that this curiosity would lead me into what my career is today: an entomologist.â
âBut growing up in a rural village there were no role models; there were no scientists. There were no people I could look up to and be inspired to know that you could make a career out of entomology or that you could be a woman in science.â
Despite initially considering a career in accountancy, Ngumbi ended up studying for a BSc in biochemistry and zoology at Kenyatta University, where she immediately fell in love with practical research. âStepping into the lab was such an exciting day for me,â she recalled. âI had so many questions, and I remember not wanting to leave because I wanted to answer all the questions I had grown up with.â
Later, extra-curricular experience at a local research center would feed her interest in entomology. The scientists she ended up working with ran a biological control program to assess how maize is impacted by lepidoptera pests, and the natural biological control agents that could be used to combat these. âHow do plants communicate and call for help? Through releasing a chemical. I discovered that there is a wave of communication happening between our food crops and the community of organisms that associate with plants.â
Eager to learn more, Ngumbi went on to pursue an MSc before joining a Ph.D. program at Auburn University in Alabama, USA. âMy parents had always told me that education is the gateway out of poverty, and they consistently encouraged me to go to the highest level. I knew I had to go to the top.â
At Auburn she had the opportunity to delve deeper into how plants defend themselves, and her successful research into beneficial soil microbes led to at least three U.S. patents. Following a few post-doctoral positions, she landed a role at the University of Illinois Urbana-Champaign, where she currently works as an assistant professor in the Departments of Entomology and African American Studies.
Bringing others along
Ngumbi credits mentorship with getting her to where she is today. âAt Kenyatta University my teachers saw a spark in me; I was curious and wanted to find answers. Mentors introduced me to scientists the International Centre of Insect Physiology and Ecology (ICIPE), so I could carry out experiments beyond what we were doing as part of my course.â
She recalled walking across the stage during her Ph.D. graduation ceremony, a key moment of reflection. âIt was real that there were very few women like me in science. That I was only one of the many women I had grown up with that was privileged to have a PhD. And I wanted not to be the only person,â she said. âI wanted to make sure that I would leave open the same door I had walked through. That I would do my best to bring other women along.â
âI would step up to be a mentor. Step up to encourage other women. Step up to encourage other children from rural communities to say: you can do it, you can dream, you can follow your passions, you can be a scientist.â
With this in mind, Ngumbi ensures she collaborates with others in all areas of her research, incorporating young researchers into her labs and working directly with farmers. âIâm committed to ensuring that farmers who work so hard â especially smallholders â can grow crops and see all their hard work pay off.â
âI will continue to follow this journey of finding solutions to feed our growing planet, but I know that I cannot do it alone. We need all of us,â she added. âWe still have very few women scientists â UNESCO estimates around 30% â and I hope that by the time Iâm done with my career that number changes. But itâs going to depend on all of us.â
Ngumbiâs talk was followed by a Question and Answer led by Olivia Odiyo, a CIMMYT research associate based in Nairobi. The full discussion can be viewed online here. Spanish and French-language audio is also available.
