CIMMYTâs work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.
CIMMYT, in collaboration with CGIAR, is leading the charge in Kenya to close the gender gap in agricultural research, particularly in plant breeding stations. Through initiatives like targeted training programs and infrastructure improvements, they’re empowering women to take on roles traditionally dominated by men. This includes offering tractor driving courses and adapting facilities to meet women’s needs. Lourine Bii’s success story, rising to oversee plant breeding trials, exemplifies how investing in women not only furthers gender equality but also enhances research quality and relevance by incorporating diverse perspectives into agricultural innovations.

Partners from the Africa Dryland Crop Improvement Network (ADCIN) from 16 institutes in Africa came together for a four-day workshop in Nairobi, Kenya, during 19-22 September 2023, to critically review and optimize breeding pipelines for newly formed breeding programs. The meeting provided an opportunity for multidisciplinary scientists to better understand each other’s significant roles and contributions in achieving optimized breeding pipelines.
Nine female and 28 male scientists working across 14 countries made up the group of experts at the workshop, which included crop breeders, quantitative geneticists, crop protection scientists, genomics experts, and data analysts. Together, they collaboratively developed, assessed, and refined the various stages and processes of breeding pipelines. Most participants were crop breeding leads from the national agricultural research and extension systems (NARES) and CGIAR Research Centers, as well as members of the Breeding Informatics Working Group A, the first of its kind as a strategic leadership group of crop breeding experts.
The workshop sponsored by CIMMYT focused on improving genetic gains across six crops: chickpea, pigeon pea, finger millet, pearl millet, groundnut, and sorghum. The workshop was organized by CIMMYT experts, Abhishek Rathore, breeding data and informatics expert, Keith Gardner, quantitative geneticist, and Roma Rani Das, biometrician, and quantitative geneticist experts from the CGIAR Accelerated Breeding Initiative, Dorcus Gemenet and Christian Werner.
Multidisciplinary expertise in action
Under the guidance of the Associate Program Director and the Breeding Lead for Dryland Crops, Harish Gandhi, participants engaged in an array of advanced genetic approaches, statistical techniques, and quantitative concepts presented by the participating experts from CIMMYT and CGIAR Accelerated Breeding.
Each breeding program schema was reviewed from detailed quantitative genetic aspects and agreed project criteria, including choosing parents, the optimum number of parents, crossing designs, the number of generations, methodologies, testing strategies, and analytical frameworks. The group deliberated on the breeding strategies tailored for respective market segments and target product profiles to further improvise and optimize breeding pipelines to enhance the programsâ efficiency.
Agreements were reached on the number of founder parents, the number of crosses and progenies in various generations, line development method, evaluation and testing strategy, time until parental selection (cycle time), marker assisted selection (MAS), genomic selection (GS) strategy, making routine use of molecular markers for QA/QC. The team also finalized the breeding strategies tailored for respective market segments and target product profiles to further improvise and optimize breeding pipelines aimed at higher genetic gains.
In coordination with crop breeders from CIMMYT, the NARES dryland crop breeding leads presented the current schematics of breeding pipelines for both line and hybrid breeding, highlighting the market segment, Target Product Profile (TPP) and Target Product Environment (TPE).
The breeding informatics team also showcased the upcoming Dryland Crops Trial Information System dashboard, a one stop shops to capture, host, and provide information on the trials organized by the networkâs NARES breeders across Africa.
The value of partnership working was frequently highlighted by the speakers. Michael Quinn, lead of the CGIAR Accelerated Breeding Initiative, gave an overview of the initiativeâs objectives and high-level goals in 2023, emphasizing the need to foster dialogue and alignment across breeding teams. He also underlined the importance of such hand-in-hand meetings for fostering cross-regional and cross-institute learning.
âPlant breeding has always been at the center stage of crop improvement, but it has become more and more important lately, and there is a need to bring more collaborative efforts across disciplines to realize higher genetic gains in our breeding programs,â said Kevin Pixley, Dryland Crops program director and Wheat program director during his virtual presentation.
âInteraction with the breeding leads from CIMMYT and the NARES in East and Southern Africa (ESA) and West and Central Africa (WCA) and other experts helped in cross learning from the advanced breeding programs,â said Maryam Dawud, plant breeder at the Lake Chad Research Institute in Nigeria. Such workshops are needed for developing optimized breeding pipelines, and we will need more such in-person workshops on advanced data analysis.â
Next steps for dryland crops
During the workshop, network partners came up with an optimized breeding pipeline incorporating advanced quantitative genetic and statistical principles aligned with the latest scientific advancements and market demands. The group further developed a six-month actionable plan split by region to address common bottlenecks across the crops, such as capacity building in data analysis, modernizing digital infrastructure, training and enhancing human capacity in the use of equipment, and managing staff turnover.
All these deliberations provided the network partners with better insights and hands-on-experience to design their breeding pipeline, outlining specific steps, responsibilities, and timelines for implementing the identified optimizations. This preparatory work will ensure there is a targeted and coordinated effort toward pipeline enhancement and accelerated genetic gain for dryland crops in the region.
Happy Daudi, head, Groundnut Research Program at Tanzania Agricultural Research Institute (TARI), who participated in the workshop, stated, âBringing in multidisciplinary experts provided a great opportunity to integrate various concepts of population improvement, product development, and deploying advanced statistical approaches for optimizing our breeding pipeline for achieving higher genetic gains, and accelerated variety turn over.â
Thank you to the Bill and Melinda Gates Foundation, the United States Agency for International Development (USAID), and CGIAR, for their generous funding which made this workshop possible.

In Zimbabwe, the traditional, laborious, and time-consuming small grain processing may soon belong to the past, thanks to a game-changing technology: a multi-crop thresher. This scale-appropriate machine offers a smarter and less strenuous way to produce high-quality small-grain meals, including in drought-prone regions, without being contaminated with sand or stone particles.
âOne of the main impediments to large-scale adoption of sorghum and millet in drought-prone areas is the laborious task of threshing. This has been solved by introducing multi-crop threshers, which form a central part in the business of mechanization service providers in rural Zimbabweâ, says Christian Thierfelder, principal scientist and project lead for the Mechanization and Extension Activity.
The introduction of the multi-crop thresher not only alleviates the physical strain of manual threshing but also enhances the overall quality of small-grain products. This innovation is a crucial step forward in promoting the production and consumption of small grains in Zimbabwe, contributing to food security and improved livelihoods for farmers.
This innovation was introduced by the Feed the Future Mechanization and Extension Activity, implemented by CIMMYT and funded by the United States Agency for International Development (USAID), to address the challenges of traditional small grain processing and offer new market opportunities to farmers.

Small grain production and consumption has traditionally been a household favorite in Zimbabwe due to its rich nutritional content. However, the sand content and gritty texture, often associated with sorghum or millet meals, have led to a decline in consumersâ interest in it. The main culprit? The traditional method of manual threshing on the soil, a strenuous and time-consuming process that incorporates sand and gravel particles into the threshed grains (and then into flours), resulting in an unpleasant eating experience.
In Zimbabwe and across the region, small grain processing has been characterized by the arduous task of manual threshing using sticks. Women, often at the forefront of this task, repeatedly beat the heads of small grains on hard surfaces, such as granite or hard clay, to separate the grains. Despite efforts to minimize contamination by threshing them into sacks or on plastic sheets, the gritty taste persists. The subsequent winnowing, roasting, and milling do little to eliminate tiny soil and stone particles from the final product (flour) as physical separation is technically challenging.
The multi-crop thresher for smooth results
âPowered by an 8 HP diesel engine, the multi-crop thresher is a perfect machine to process sorghum, millets, maize (husked or un-husked), wheat, cowpea, sugar beans, and soybean,â says Abdul Matin, mechanization specialist and technical lead of the Mechanization and Extension Activity. âIt is locally made in Zimbabwe and designed to promote mechanization as a business as it can easily be transported. It has high threshing efficiency, is fuel-efficient, easy to operate, and women friendly.â
The operator simply feeds the crop into the inlet hopper, and as it passes through the threshing drum, the machine efficiently separates the grain from the chaff, releasing clean grain through the outlet chute. âThe thresher will help reduce decline of small grain production in the country and complement government efforts to expand its cultivation in Natural Regions IV and V in Zimbabwe,â Matin added. When operating the machine efficiently, one can thresh up to 0.5 tons per hour for small grains.

CIMMYT organized awareness meetings, including the 2023 Seed and Mechanization Fairs, for farmers to witness the speed and quality performance of the multi-crop thresher. They could also assess the quality of pearl millet processed using the thresher and others threshing wheat in an irrigation scheme showcasing the efficiency of the process and improved grain quality.
“In our region, harvesting small grains was always laborious,” explains Paidamoyo Kaseke from Ward 4 in Chimanimani district, Manicaland province. “But thanks to the multi-crop thresher, it’s now much easier. It operates quickly and efficiently, delivering clean grains that we can promptly take to the mill. This technology has revolutionized our harvesting process, significantly reducing the time and effort required.”
“Not only do we promote new and effective technologies such as the multi-crop thresher in the project, but we also seek solutions for farmers without high incomes to be able to afford the thresher. That is why we are partnering with two Zimbabwean banks to make small-scale loans accessible to farmers at affordable rates and tenure times. This way, we can effectively scale the access to scale-appropriate mechanization solutions.â says Leon Jamann, chief of party for the Mechanization and Extension Activity.
As the 2023-2024 farming season has been dry with erratic rainfall, rainfed dependent farmers already face drought in large areas of Zimbabwe. However, the promotion of more climate-resilient small grains in 2023âdeclared by the United Nations the International Year of Milletsâemphasizes their adaptability to climate change and their high nutritional value. The multi-crop thresher, a vital component of this initiative, ensures that farmers can efficiently process small grains despite the challenging climate conditions.
In the heart of Itumbula village in the Songwe district of Tanzania lives Venansia Swale, a farmer, mother, and community champion, who is turning the tide against food insecurity through the power of quality seeds. Swale has taken on the role of promoting improved seed in her community after experiencing firsthand the benefits of growing sorghum on her own farm with different seed.
“As a mother of five children, my biggest challenge is food shortage, and sorghum is our staple food,â said Swale. “Normally, I would harvest 450 kg from my three-acre farm, which isn’t enough for my family’s needs and leaves little surplus for selling. However, using quality seed this season, I harvested 990 kg. I’ve seen the benefitsânot only can I feed my children for a year, but I can also earn income from the surplus.”

Swale’s efforts began to extend beyond her own farm as she championed demand creation and consolidation in her village of Itumbula. She successfully created a demand of 574 kg, becoming her community’s sole distributor of quality sorghum seed. In the 2022-2023 season, she facilitated the supply of 134 kg of quality sorghum seed and 50 kg of quality maize seed.
So far, she has reached 300 farmers in partnership with CIMMYT and the Tanzania Agricultural Research Institute (TARI), sparking a transformative movement. One local farmer said, “As a community, we have come together to embrace quality seed, and Venansia has been at the forefront of this movement. Her dedication has significantly impacted food security.”
Despite being pregnant during the 2022 “Kizazi cha Mabadiliko” (the generation that will bring change) campaign, Swale remained unwavering in her determination and passion. She exemplifies the success of the Social and Behaviour Change interventions implemented by the Centre for Behaviour Change and Communication (CBCC).
The “Kizazi Cha Mabadiliko” campaign was developed and launched by CBCC in the Mbozi and Momba districts of Tanzania, aiming to increase awareness of the benefits of improved seeds. It was also designed to challenge negative perceptions and enhance motivation for participating in agricultural activities. The campaign underscores the importance of using improved seeds as a foundational element for a prosperous future in agriculture. The strategic design of the campaign ensures the efficient distribution of behavior change tools and materials, further demonstrating its impact through Swale’s inspiring example.
Sprouting new opportunities

Despite her impressive achievements, Swale remains forward-thinking. The village extension officer notes that while farmers have adopted improved seeds, poor farming practices persist, impacting yields. Inspired and invigorated, Swale plans to revolutionize her farming practices in the upcoming season, aiming for an even more significant impact.
Besides her role as a community champion, Swale is a member of the Sifa choir in her church. Leveraging her influence, she convinced nine fellow choir members to join the intervention, where they established and managed sorghum demonstration plots in their locality. The performance of quality seed inspired the choir to enlist as seed producers, and they secured two acres of land for seed production in the 2023- 2024 season.
Venansia’s vision goes beyond her own farm; she plans to produce seeds as part of the choir group and individually, allocating an acre for seed production and two acres for grain production. Hers is a story of personal triumph, showing the impact one person can have on an entire village, and a testament to the transformative power of community-led initiatives.
“The seeds we plant today will grow into a better tomorrow for all of us,” asserts Swale.
The Angola Smallholder Agriculture Development and Commercialization Project (SADCP or MOSAP2), with crucial input from CIMMYT, markedly improved food security and income for 179,000 smallholder farmers in Angola from 2016 to 2022. By introducing 4,000 Farmer Field Schools and innovative agricultural practices, including CIMMYT’s improved seeds, the project boosted crop yields by up to 196% and increased the sale of produce significantly, showcasing the transformative impact of integrating scientific research with farmer education in post-conflict agricultural recovery.

From the rich plateau landscapes of Angonia district in the Tete province of Mozambique emerges a tale of determination and hard work. Juliana Nicolau Moises, a mother of four, has been a devoted soybean farmer for more than a decade, tending to a crop whose pods carry the potential for value-added products, including milk and porridge for her children. But one wonders, what motivates smallholder farmers like Juliana to invest their efforts in soybean production.
âI have never looked back on producing soybeans,â reflects Moises. âThis legume crop has allowed me to feed my family and meet my household needs, let alone the cash income from sales of the surplus crop. It has taken a lot of hard work and resilience to navigate through the complexities of soybean production.â
Entering her second season of implementing the Chinyanja Soy Use Case trials with CGIAR’s Initiative on Excellence in Agronomy, delivered in partnership with CIMMYT and the International Institute of Tropical Agriculture (IITA), Moises eagerly anticipates a bumper harvest in the early planted fields. She has been avidly implementing trials on planting dates to establish the implications of early, mid, and late planting on soybean yield. Let alone the required attention to detail, she exudes a deep understanding of the significance of the trials by carrying out key agronomic practices to ensure a good harvest. This will not only nourish the health and wellbeing of her family but also symbolizes the fruits of her dedication.
Moisesâs commitment extends beyond the trial she hosts as she implements her learning from the project to other fields, using innovative approaches like the double-row planting method. In soybean farming, this involves planting two rows of seeds on a wider ridge established on the traditional spacing that farmers use on maize. Traditionally, farmers in Angonia have been planting single rows of soybean on ridges spaced at 90 cm used for maize, thereby resulting in low soy plant populations and ultimately low yields. This different technique optimizes the plant population and land use efficiency, improving yields, and facilitating easier weeding.

Despite the promise of enhanced production, challenges persist. Southern Africa continues to face a growing demand for soybeans, with annual productivity of 861,000 metric tons (mT) falling short of the 2-million-ton demand. In Mozambique, vibrant soybean farms blanket the landscape, yet smallholder farmers like Moises grapple with underdeveloped markets and climate-related adversities, such as droughts and floods currently worsened by the El Niño phenomenon.
âAs a devoted soybean farmer, I have met my own fair share of challenges. One of our biggest challenges is the labor requirement across the production season,â shared Moises as she navigates through her fields. âWe need machinery for planting, weeding, and harvesting in order to reduce the labor and drudgery associated with soybean production. In addition, markets remain a challenge.” Her unwavering commitment inspires neighboring farmers, creating a ripple effect of hope and determination in the community.
Sharing the same sentiments is Veronica Ernesto Gama, who teams up with her husband every year to tend to her soybean field. Having started in 2007, their yields have sustained the food basket of her family while meeting nutritional needs. âIn the past, I used to just scatter around soybean seeds in one place, but after these trials, I have learned the significance of applying the agronomically recommended spacing and the need for quality improved seeds to ensure a bumper harvest,â said Gama.
The power of collaboration
Addressing these challenges head-on is CGIARâs Excellence in Agronomy Chinyanja Triangle Soy Use Case, a collaborative effort aimed at strengthening the soybean industry primarily by empowering farmers with improved agronomic practices and decision support. Solidaridad, an international non-government organization (NGO) pursuing digital platforms for scaling agronomy, serves as the demand partner of the Excellence in Agronomy Chinyanja Triangle Soy Use Case, while CGIAR provides technical support. Solidaridadâs role is vital in catalyzing demand for the product or service in question. Research outputs drawn from the trials will be used to develop a mobile phone application on the Kvuno, a social enterprise borne out of Solidaridad. The platform will support farmers with onsite advisories on planting dates, site-specific fertilizer recommendations, variety selection, and crop configurations.
To date, the initiative has drawn the willingness of 70 farmers in the Angonia district of Tete province, who are implementing different suites of trials, including nutrient omission, planting date, plant configuration, and fertilizer usage. Excellence in Agronomy has come at an opportune time for smallholdersâ journeys in soybean production, emphasizing the importance of optimized spacing and improved agronomic practices.
As the story unfolds in Mozambique, women like Moises and Gama are the unsung heroes driving soybean production. Their dedication, coupled with initiatives like Excellence in Agronomy, paint a picture of progress and potential. Their commitment inspires many surrounding farmers who draw inspiration on the trials in their fields. As the sun continues to rise over the dusty soils of Angonia, it showcases not just Moisesâs fields, but the bright future of soybean production in the hands of resilient women farmers.
At a business expo in Mwenezi, organized by NGOs including Junior Achievement Zimbabwe and Silveira House, with funding from Plan International Zimbabwe, CIMMYT showcased its products and services. Aimed at empowering youth through entrepreneurial projects, the event provided a platform for young entrepreneurs to connect with potential suppliers and clients, including leading organizations like CIMMYT, which exhibited alongside others to support economic development through value chains.
Recognizing that equitable access to finance and credit are key enablers for mechanization, this platform strived to understand smallholder farmer needs and the identification of key financing models to facilitate widespread adoption.
With over 40 participants ranging from government representatives, development partners, and stakeholders from organizations such as USAID, the Food and Agriculture Organization (FAO), the International Institute of Tropical Agriculture (IITA), the International Fertilizer Development Center (IFDC), and Hello Tractor, this regional event provided an opportunity for robust discussions and to align the course of action.
Unpacking mechanization in the Global South
Appropriate-scale mechanization is essential and a top policy priority to transform African agriculture. Evidence shows that nearly 70% of operations in sub-Saharan Africa are done manually. However, human labor is limited and is increasingly scarce and costly given the unfolding transformation of rural spaces in most places, necessitating agricultural mechanization. The cornerstone of this shift lies in integrating small, affordable machines tailored to the operations and needs of smallholder farmers, which must be accessible through market-based financial and business models.
A top policy priority in Zambia
The Permanent Secretary, Technical Services of the Zambian Ministry of Agriculture, Green Mbozi, officially opened the meeting. He lauded the meeting as timely and commendable as agriculture mechanization is a top policy priority for Zambia.

“The government has embarked on a process to formulate a national mechanization strategy, which will serve as a blueprint on how to sustainably promote agricultural machinery and equipment across the value chains. The insights from this workshop would be helpful in feeding into the formulation of the strategy and help in identifying entry points to support sustainable agriculture mechanization,â said Mbozi.
Accelerating change through inclusive dialogues
The dialogue played a crucial role in bolstering support for sustainable agriculture mechanization while tackling challenges hindering active adoption. Mbozi highlighted the imminent launch of an agricultural mechanization strategy developed with technical support from FAO and CIMMYT through the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project.
The mechanization strategy champions sustainable and efficient mechanization practices, strengthens the private sectorâs role in mechanization, and provides training and financial support to small-scale farmers, women, and youth. Proposed initiatives include regional centers of excellence, a national mechanization association, and the use of information and communication technologies to promote mechanization.

âIt is important to develop the right bundle of mechanization services that meet the needs of farmers and are profitable for mechanization service providers,â said Director of Sustainable Agrifood Systems (SAS) at CIMMYT, Sieg Snapp. âFinding the right financing is needed to support multiple bundles of mechanization services, which provide profits throughout the year.â
Additionally, the SIFAZ project promotes local manufacturing, supporting quality assurance, conducting demand studies, and establishing an agricultural mechanization data bank to catalyze transformative progress.
Key insights from USAID and FAO
David Howlett, the Feed the Future coordinator at the USAID Mission in Zambia, shared with participants that, âUSAID is working to address the effects of climate change through mechanization and other adaptation strategies.â Aligning with the central focus of the meeting, he further reiterated that mechanization will be key to building resilience by improving agricultural systems.

Offering insights drawn from country-level experiences on scale mechanization for smallholder farmers, Joseph Mpagalile from FAO said, âFAO has been helping countries develop national agricultural mechanization strategies, with 12 countries in Africa already revising or preparing new strategies for sustainable agricultural mechanization.”
Private sector engagement: lessons from Hello Tractor
Operating across 13 African countries, Hello Tractor has been leveraging digitalization to scale mechanization in Africa since its inception. Hello Tractor facilitates services to over 500,000 smallholder farmers through 3,000+ tractors and combine harvesters, while providing remote tracking of assets and preventing fraud and machine misuse for machinery owners. At the heart of the company are booking agents who connect farmers to solutions to increase productivity and income.
Call to action
As the discussions ended, key outcomes distilled highlighted a pressing need to sensitize farmers on the merits of mechanization and facilitating access through tailored financial resources. Special attention was also directed towards empowering women and youth through implementation of de-risking mechanisms and strategic marketing linkages.
Recognizing the critical absence of data, a compelling call for a funding pool to collect essential information in the ESA region became clear. In addition, it was emphasized that appropriate-scale mechanization should be driven by sustainable business and financing models. The journey towards mechanization is a collective effort, blending policy initiatives, private sector engagement, and research-driven strategies.

The East African wheat breeding pipeline aims to improve wheat varieties and contribute to regional food security by ensuring a stable and resilient wheat supply. In 2022, CIMMYT, in partnership with the Kenya Agriculture and Livestock Research Organization (KALRO) established a Joint Breeding Program in Njoro, a town southwest of the Rift Valley in Kenya. This was one of the first integrated breeding pipelines between CGIAR and National Agricultural Research and Extension Systems (NARES) partners.
Over the last three decades, genetic trials of over 77 varieties have been conducted in several regions. In East Africa, an expanded testing network that spans over multiple research institutes in Kenya and Ethiopia has been established for Stage 1 and Stage 2 trials in network countries. This makes the pipeline a powerful driver of positive impacts, rapidly enhancing both farm productivity and production in target regions. In Kenya specifically, a genetic gain trial was conducted at two sites in 2023 with the Stage 1 trials evaluated across eight locations. These are being distributed to NARES partners to establish correlations between the breeding site in Kenya and the Target Population of Environments (TPEs) in the E&SSA regions. This breeding pipeline demarcates the population improvement from product development. Other areas in the trials include the enhancement of genetic diversity to build resilience, adaptability, and quality enhancement to meet market and consumer demands.
The trial will continue in 2024 and 2025 to establish a baseline for genetic gains and to enable the assessment of the breeding pipeline’s progress in the coming years. The first cohort of pipeline materials (250 crosses) has been advanced to F2 generation and will be ready for distribution to E&SSA partners in 2025.
Accelerated breeding
The anticipation is that accelerated breeding techniques will be implemented in Kenya by incorporating a three-year rapid generation bulk advancement (RGBA) scheme aimed at diminishing the time necessary for variety development and release. This collaborative effort encompasses various activities, including joint crossing block, generation advancement, yield testing, and population improvement. The three-year RGBA scheme, coupled with data-driven selection utilizing advanced data analytics (GEBV, SI) and genomic selection approaches, is expected to play a pivotal role in facilitating informed breeding decisions in the East African region.

Varietal improvement
The project aims to develop and release improved wheat varieties that are well adapted to the East African agroecological conditions. The Kenyan environment closely mirrors wheat-growing conditions in Ethiopia, Tanzania, Uganda, Rwanda, and Burundi, and spillover impacts to sub-Saharan countries such as Zambia and Zimbabwe. This strategic alignment with local conditions and close cooperation with NARES partner organizations has proven to be very effective in addressing critical gaps, including high-yield potential, disease resistance, and climate resilience, and aligns with CIMMYTâs overall wheat strategy for Africa.
Enhanced disease resistance
Kenya stands out as a hotspot for rust diseases, showcasing notable diversity in stem rust variants (ug99) and yellow rust. The virulence spectrums of these diseases differ from those found in Mexico, posing challenges to effective breeding strategies. It is expected that the breeding pipeline will effectively tackle these challenges as well as those associated with fusarium, Septoria, and wheat blast, which are on the rise in African environments.
Climate adaptation
The East African wheat breeding pipeline is committed to breeding wheat varieties that can thrive in changing climatic conditions, including heat and drought tolerance, and expanding testing in marginal rainfed environments experiencing heat and drought stress.
Through the support of our partners and funders from the Bill and Melinda Gates Foundation, Foundation for Food and Agriculture Research (FFAR), and Foreign, Commonwealth and Development Office FCDO, the following achievements can be reported:
Regional collaboration and cooperation
For over four decades, the enduring collaboration with KALRO has yielded significant successes including the operation of the largest phenotyping platform for stem rust and various diseases. The Mexico-Kenya shuttle breeding program, incorporating Ug99 resistance, has successfully countered the threat of stem rust by releasing over 200 varieties in targeted regions and advancing the East African wheat breeding pipeline. The plan is to replicate these accomplishments in other target regions through the E&SSA network. To address limitations in KALRO’s breeding program and to conduct standardized trials, a strategic partnership with a private seed company Agventure Cereal Growers Association has been established. This collaboration will facilitate yield testing at multiple sites in Kenya to identify lines with superior performance for the East African region. So far, lines exhibiting high yield potential of up to 8 tons/ha, even under rain-fed environments, have been identified. The collaborative efforts are already making a noticeable impact, as evidenced by reports indicating increased adoption of zero-tillage practices among farmers. This shift has proven beneficial, especially during years marked by heat and drought challenges, resulting in higher returns for these farmers.
Increased capacity of national programs
From 1-13 October 2023, the AGGMW project held a training program on “Enhancing Wheat Disease Early Warning Systems, Germplasm Evaluation, Selection, and Tools for Improving Wheat Breeding Pipelines”. The course which brought together 33 participants from over 13 countries was held at the KALRO station in Njoro- Kenya. The comprehensive program covered a wide range of crucial subjects in the field of wheat breeding and research. Topics included breeding methodologies, experimental design, data collection, statistical analysis, and advanced techniques such as genomic selection. Participants also engaged in practical hands-on data analysis, explored rust pathology, and delved into early warning systems. Moreover, they had the opportunity for direct evaluation and selection of breeding materials. The course aimed to equip participants with a diverse skill set and knowledge base to enhance their contributions to the field of wheat breeding and research.
Other initiatives supporting the breeding pipeline include CGIAR programs, Accelerated Breeding and Crops to End Hunger. This multi-faceted approach within the breeding pipeline underpins the importance of fostering regional collaboration, knowledge sharing, and strategic investments in enhancing wheat production and addressing critical challenges in the region.
Farmers are guided on how to use Atubandike and VIAMO. (Photo: CIMMYT)
It is challenging to disseminate information across far-flung areas of rural Zambia as extension officers must travel vast distances to reach farmers. The Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub, managed by CIMMYT and funded by the United States Agency for International Development (USAID) helps alleviate these issues by engaging with existing mobile phone networks to reach farmers with agronomic information, weather data, and soil information.
To introduce farmers to these specific tools: Atubandike and VIAMO, AID-I conducted a community sensitization and engagement exercise in Zambia. Atubandike emphasizes farmer learning and feedback using mobile phones for disseminating knowledge about the new generation of drought-tolerant varieties, sustainable intensification practices, and collecting farmer feedback to enable demand-driven delivery under AID-I. VIAMO, accessible via a basic mobile phone, provides agronomic information for every farmer in a specific area. The platform comes in different languages and farmers access information on various crops such as maize, beans, and groundnuts in their native language, provide feedback on information content, and connect with other farmers.

In Choma District, Morgan Katema, who provides extension services to farmers, explained that going digital is one way of reaching farmers through technology to ensure that all farmers have access to extension services. âIn this case, lessons will be available through mobile phones and farmers will ask agriculture-related questions and get a response. This is a good initiative because farmers can access information on the spot instead of waiting for an extension officer to reach them, and information can be accessed after working hours, and the VIAMO initiative will help us overcome the challenge of long distances between farmers as we will no longer need to travel long distances,â Katema said.
Judith Simuliye, a farmer who grows maize and groundnuts, said, âI was told about this meeting by the camp officer, and I am happy to learn about this project. I have learned how to manage my crop by using the right seed varieties and how to space the crops.â
During the meeting, two community facilitators were selected through a voting process, after farmers nominated community members who are literate, trustworthy, energetic, and able to use a smart phone. Facilitators register farmers on the VIAMO platform, assist them in accessing the information they require, and support them in their learning journey.
Namasumo Rithay, a farmer in the village of Kalalasa, said, âMobile phone access to extension services has come at the right time. We have faced a lot of challenges with the poor rain patterns and pests. Through this meeting organized by AID-I, we have learned how we can obtain information to mitigate these challenges through our mobile phones.â

Agriculture feeds the world. Yet traditional cycles of ploughing, planting, and harvesting crop and biomass products is inefficient of labor and other scarce resources and depletes soil health while emitting greenhouse gases that contribute to climate change.
One effort to ameliorate the negative effects of farming is a set of practices referred to as conservation agriculture (CA), based on the principles of minimal mechanical soil disturbance, permanent soil cover with plant material, and crop diversification.
To deliver advanced, high-level instruction on current innovative science around important aspects of cropping and farming system management to scientists from India, Bangladesh, Egypt, and Morocco, the 12th Advanced Conservation Agriculture Course hosted by the Indian Council of Agricultural Research (ICAR), CIMMYT, and the Borlaug Institute for South Asia (BISA) took place in India from December 10 to 24, 2023.
SK Chaudhari, deputy director general for Natural Resource Management, ICAR; HS Jat, director of the Indian Council of Agricultural Research-Indian Institute of Maize Research (ICAR-IIMR); Arun Joshi, country representative for India and BISA managing director, CIMMYT-India; Mahesh K. Gathala, senior systems agronomist and science lead, CIMMYT-Bangladesh; and Alison Laing, agroecologist, CIMMYT-Bangladesh, all attended the opening ceremony at the National Agricultural Science Complex in New Delhi, India.
This CA course integrated scientific advancements and multidisciplinary techniques to sustainably develop agricultural systems, restore natural resources, and improve climate resilience in agriculture throughout Asia and North Africa. It was held at leading research centers throughout India.
SK Chaudhari welcomed delegates to the course and stressed its practical character and efficacy in promoting CA management innovations, as evidenced by the significant achievements and international reputations of many former attendees and resource personnel.
âAs climatic variability and change increase, the need to manage agronomic risks grows, and CA is an effective tool for farmers and scientists in both irrigated and rainfed systems,â said Chaudhari.
Twenty rising scientists from such fields as agronomy, soil science, plant protection, agricultural engineering, plant breeding, and extension, took part in the workshop where they gained a better understanding of all aspects of conservation agricultural methods in rainfed and irrigated ecosystems, as well as exposure to wide networks with prominent international scientists. Organizers prioritized the inclusion of female scientists, who made up 40% of attendees.
The workshop empowered participants to act as conservation agriculture ambassadors and champions of modern, novel agronomic methods when they return to their home institutions.
Rajbir Singh, ICAR assistant director general for Natural Resource Management, and ML Jat, global research program director of Resilient Farm and Food Systems, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) provided keynote addresses at the closing ceremony, held at the ICAR-Central Soil Salinity Research Institute in Karnal, Haryana, India.

Much has changed since many CIMMYT scientists attended university. In the past decades, the STEM field was predominantly male, with far less representation from marginalized groups and communities. Challenged by societal prejudices, only a handful of young women pursued STEM subjects, which further influenced career choices made by them, reinforcing the gender gap.
The gender gap in STEM is still significant, but times are changing. âAt CIMMYT, we are deeply committed to promoting the voice of youth, marginalized communities, and women to improve the rigor of science for sustainable development. This includes investment in mentorship, learning from champions and pioneers, and appropriate performance assessment guidelines,â said Program Director of CIMMYT’s Sustainable Agrifood Systems, Sieglinde Snapp. âIt is a long journey with bumps along the way, but I am proud to be in solidarity with the Global South, where we champion gender and social inclusion every day.â
On International Day of Women and Girls in Science 2024, five CIMMYT scientists who inspire, support, and open doors for many young women and underrepresented groups with their scientific work and pay-it-forward commitment share their motivation behind charting a career in STEM and encourage more young women and make the field more inclusive.

Hailing from a farming family, Beyhan Akin was always surrounded by the beauty and potential of agriculture. She wished to contribute to her farming community, so 35 years ago, she joined CIMMYTâs wheat research program. Akin reminisced about her early days, how there were few women scientists, and the realization that if she succeeded, she could motivate more to follow in her footsteps.
“Agriculture science is expanding beyond core crop science with huge potential for interdisciplinary research and innovation. I hope young women students and scientists get the opportunity to pursue and excel in these fields. Increased advocacy and investmentâgrants, fellowshipsâat an institutional level is crucial to motivating and supporting the aspirations of women in science,â said Akin. âIt might have taken a long time for women scientists like us to be in positions of influence, but I hope we can ensure the path is far less challenging today for these young women pursuing agriculture science/STEM.â

“Search out mentors. Donât be afraid to either ask for help when you need it or to promote your achievements. And build networks,â advises Alison Laing to young women scientists starting in the field. Based in Bangladesh and working across South and Southeast Asia for over 15 years, Laing hopes that girls have opportunities to choose science education and become women with rewarding careers in fields that interest them, especially in non-traditional STEM disciplines.
Laing remembers how her mentor early in her career, the late John Schiller, a rice agronomist at the International Rice Research Institute (IRRI), encouraged her enthusiasm for learning and research. âHe taught me so much about doing research in Southeast Asia, and I am indebted to him for his motivation and support in showing me how rewarding and interesting a scientific career can be.â She hopes other young students and scientists will have such mentors in their lives.

Fascinated by nature, plants, and how they thrive in diverse environments, Sabina Tiwariâs journey in science led her to become a plant breeder. âThe indefinite potential of agriculture to improve lives made me realize how powerful agricultural science can be. This led to the motivation that I could create a positive difference in the world by being part of crop science and technology while working alongside great scientific minds, both men and women. Today, to young girls aspiring to make a difference in the world, I recommend they empower their cause through science and innovations.”
According to Tiwari, mentorship programs, internships, and job-shadowing experiences that helped her career must be extended to young women to gain practical exposure and knowledge of the possibilities in agriculture science.

“A feminine perspective and approach are needed to enrich research,â reminds Luisa Cabrera Soto. âIn a society where almost half of the members are female, I hope equity and inclusion will help improve under-representation in STEM.â
According to Cabrera, it is essential that women in science continue to challenge the gender prejudices and stereotypes that still exist. âDon’t let the spark of your curiosity go out. As a food science professional, I can say that there are still discoveries to be made and, through it, the probability of finding innovative solutions to global challenges such as food security.â
In Busia, Chris Ojiewo from CIMMYT and partners are spearheading the adoption of high-yielding millet varieties to boost food security and tackle climate change. This initiative aims to equip farmers with quality seeds and modern farming techniques, ensuring the sustainable cultivation of millet, a crop resilient to harsh climates.

Mutoko, a semi-arid area located in Mashonaland east of Zimbabwe, is prone to droughts and unpredictable rainfall patterns. In an effort to tackle the challenges faced by local smallholder farmers in the region, partners of the Resilience Building through agroecological intensification in Zimbabwe (RAIZ) project organized a participatory workshop to amplify the projectâs mandate and gather feedback from key stakeholders. The workshop at Mutoko brought together diverse participants from the Women Affairs, Youth, and Agriculture ministries from the government of Zimbabwe, local leaders and council, extension officers, students, and farmers from Wards 10 and 8. Attending farmers and stakeholders expressed interest in the project that would enable them to face challenges and improve agricultural practices in Mutoko.
Working towards climate-smart solutions: the RAIZ project
RAIZ is a collaborative effort between CIMMYT, the French Agricultural Research Centre for International Development (CIRAD), and the University of Zimbabwe. The project is funded by the European Union, and it focuses on recognizing the strategic role of agroecological approaches in tackling climate change and enhancing sustainable agriculture in arid areas. Research operations are underway in Mutoko to produce scientific evidence and contribute to agroecology policy.
Agroecology offers climate-smart solutions that help farmers adapt to changing conditions, mitigate greenhouse gas emissions, conserve natural resources, and promote food security and resilience in the face of climate uncertainties. RAIZ implements âLiving Labsâ which strengthens collaboration between diverse stakeholders, including farmers and scientists, whose collective insights help develop demand-driven solutions.
During the Mutoko workshop, Professor and Systems Agronomist Regis Chikowo provided context of RAIZ and emphasized on its goal of helping build resilience in farmers through sustainable approaches. âThe aim is not only to help farmers adapt to climate change but also to enable them to thrive in the face of adversity,â said Chikowo.

Building synergies between research and farmer realities
To bridge the gap between research and farmer realities, six student-researchers of RAIZ are working on various aspects of building farmer resilience based on agroecological principles. Their study areas comprise of weed control, climate-proofing with resilient small grain varieties, indigenous knowledge systems, and soil health among others. One student-researcher, in collaboration with farmers, is conducting research on weed control and its impact on crop yield. In all, they are set to articulate and tackle climate change in Mutoko.
âThrough my research in weed control and how it affects yields, we are hosting trials with some farmers. We are putting into effect mulch practices gumbeze ramwari, and assessing how it affects yields. We are then intercropping maize with cowpea so that farmers spend less time fighting off weeds, while promoting crop diversification,â says Juliet Murimwa, a Ph.D. student.
Knowledge and sources of information on when to expect rains and average temperatures are vital for farmers to better plan the entire planting-to-harvesting operations. Recognizing this, research student Rejoice Nyoni is studying the types and usefulness of climate services information accessed by smallholder farmers in RAIZ project sites.
âMy research is centered on understanding whether smallholder farmers are getting enough knowledge from available sources, including radio which is more prominent,â says Nyoni. Farmers have long relied on traditional knowledge systems to predict weather patterns and plan farming activities. However, with climate change, some of these traditional knowledge sources are being altered. âThis season, I will be joining our farmers in Mutoko to discuss and understand which indigenous knowledge systems they use to gather information about weather patterns. We want to find ways to ensure that such wisdom does not get lost, as generations are slowly moving away from traditional cultures and norms,â she adds.
CIMMYTâs work in RAIZ operational areas supported by graduate students, is also testing the effectiveness of newly availed local commercial organic fertilizers and how they contribute to climate smartness when used along with conservation agriculture practices. CIMMYT is also leading the development of an agroecology handbook, set to be used by extension staff and other development practitioners.
In line with the International Year of Millets in 2023, RAIZ actively promotes the cultivation of small grains to enhance the resilience of local farmers. As part of the project, a student researcher is conducting trials in Mutoko to assess the performance of different small grain varieties in the face of climate change. Farmers in Mutokoâs Ward 10 have started experimenting with small grains and have experienced promising yields. A farmer in Mutoko Ward 10, Mudzengera, shared his positive experience with growing sorghum, âLast year we grew three varieties of sorghum. We really liked the new variety as it was not prone to bird attack. On the other hand, the native variety we usually grow is prone to birds feasting on them. We realized good yields which improved household nutrition. I look forward to another farming season with such trials on sorghum,â he says.

A shared vision for a sustainable future
A visioning exercise conducted during the workshop, solicited views from the farmers on how they envision the future of agriculture. The session, facilitated by Isaiah Nyagumbo, senior agronomist at CIMMYT, and marking the initiation of Living Laboratories in the district, started with asking farmers what change and developments they would like to see in their ward after three to four years, with respect to agriculture. The farmers were disaggregated into four groups by gender and ward. The emerging aspirations revolved around the twin goals of safeguarding the environment and enhancing crop yields. Farmers from both wards 10 and 8, expressed a shared desire to improve agricultural marketing infrastructure, agroforestry, and the protection of forests, recognizing the critical role that trees play in mitigating climate change and preserving biodiversity. Mulching, which holds immense potential in conserving soil moisture, and adopting mechanized operations were among other aspirations. Furthermore, the participants expressed interest in cultivating small grains, drought-tolerant maize, use of renewable energy, and leveraging digital platforms.
