In Tanzania, access to high-quality seeds has significantly benefited smallholder farmers by improving their livelihoods. Despite impressive economic growth, poverty reduction has not kept pace, and malnutrition rates remain a challenge.
The Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project, funded by the Bill & Melinda Gates Foundation (BMGF), led by CIMMYT, and implemented in Tanzania by the Syngenta Foundation for Sustainable Agriculture (SFSA), is an excellent example of the positive impact of supporting smallholder farmers by ensuring seed availability, access, and affordability.
Tanzanian smallholder farmers face challenges in increasing yields and incomes due to a lack of affordable, high-quality seeds, inadequate agronomic training, and limited access to reliable markets. Distance from seed suppliers and agro-dealers, along with impassable roads, exacerbate the situation. In addition, the distribution networks of private companies that produce certified seeds are very limited, especially for underutilized crops.
The Quality Declared Seeds (QDS) system is a seed production system that ensures seed meets a minimum quality standard through inspection by an official seed certification system or a designated inspector from the local government authority. SFSA, through the AVISA project, is focusing on supporting the production of QDS by community-based groups for common bean and groundnut varieties in several districts in Tanzania.

Two QDS-producing farmer groups received free Early Generation Seed (EGS) capital, consisting of 200 kg of Selian 13 bean seed, 150 kg of Tanzanut seed, and 50 kg of Naliendele 2016 groundnut seed. As a result, the groups sold 1.35 MT of QDS for common beans and 2.00 MT of groundnuts to individual farmers in the Karatu and Bahi districts respectively.
âThis initial investment by the AVISA project has, therefore, improved the incomes of these groups, and we are seeing an increased demand for larger volumes of improved seeds within seed value chain actors and off-takers,â states the Tanzanian Program Coordinator, Papias Binagwa.

Both the Tanzania Official Seed Certification Institute (TOSCI) and the Tanzania Agricultural Research Institute (TARI) have been instrumental in supporting this initiative by providing training to farmers on current regulations and seed production practices. The QDS-producing farmer groups have been hosting local smallholder farmers for informational visits and field demonstrations to showcase the use of improved varieties and agronomic practices that enhance yields. As a result, QDS-producing farmers are full of praise.
âThanks to this initiative, I have more sources of income as my yields have significantly increased from the seeds I sourced from TARI-Selian and ALSSEM seed company. The training has improved my seed handling and management. My extra agronomic knowledge will also benefit my fellow farmers,â says Baraka Hamis from Karatu district.
Joyce Yuda from the Chamwiilee Agro-Live QDS-producing group further stated, âThanks to the seed sales, I have paid my childrenâs school fees and renovated my house. My food is assured, and I have economic freedom.â
How can market intelligence and seed system insights drive varietal turnover for groundnut, sorghum, and beanstakeholders? This was the central question explored during a series of workshops convened by the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) and The Accelerated Varietal Adoption and Turnover for Open-Pollinated Varieties (ACCELERATE) projects.
Held from October 21-25, 2024, across three locations in Tanzania, these workshops were designed to identify practical solutions for improving varietal turnover.
The AVISA Project focuses on modernizing crop breeding programs and strengthening seed systems to enhance the productivity, resilience, and marketability of key dryland cereals and legumes in sub-Saharan Africa. By ensuring that smallholder farmers have access to high-quality improved varieties, AVISA contributes to better food security, nutrition, and economic development.
ACCELERATE, complementing AVISAâs efforts, focuses on market-driven adoption strategies by analyzing the requirements and constraints of both large- and small-scale marketplace traders. It aims to catalyze the uptake of new varieties through market intelligence-driven interventions and foster partnerships across formal, semi-formal, and informal seed sectors to accelerate varietal adoption and turnover.
The workshops opened with expert presentations from breeders and seed system specialists from CIMMYT, CIAT, and TARI. Key topics included the adoption of improved seeds for groundnuts, sorghum, and beans; groundnut processing for peanut butter; the sustainability of digital inclusion initiatives; challenges and opportunities in seed systems; and the increasing demand for crops such as groundnuts, sorghum, and beans. The speakers provided valuable insights into crop production, seed availability, market demand, and the desired traits for improved crop varieties.

Three separate sessions were held in Arusha, Dodoma, and Dar es Salaam, bringing together farmers, processors, traders, and researchers to deliberate on systemic challenges affecting varietal turnover. Participants then identified practical solutions to enhance the adoption of improved varieties of sorghum, beans, and groundnuts.
Opening each workshop session, TARI representatives emphasized the critical role of high-quality seeds in realizing higher crop yields and achieving agricultural growth.
âWe are here to ensure improved varieties leave shelves and reach farmersâ fields in efforts to support the envisaged 5% annual growth in agriculture,â remarked Fred Tairo, the TARI Manager in Dar es Salaam. In Arusha, Nicholaus Kuboja, TARI Center Director, Selian, highlighted the importance of market intelligence. âMarket intelligence is crucial, as market access has been a persistent challenge across African countries, particularly for smallholder farmers, in securing profitable markets for their produce.â
The Director General of TARI, Thomas Bwana, speaking in Dodoma, focused on partnerships. âWe are actively promoting the production and distribution of early generation seed, particularly breeder seed, for access by downstream seed producers. Through collaborations with other value chain actors, we strive to ensure that these seeds meet the quality standards needed by both seed and grain producers, as well as consumers who are keen on specific varietal traits,â he noted.
The subsequent discussions underscored the importance of collaboration and innovation to meet the rising demand for these vital crops.
Identifying Challenges
In experience sharing among participants across the three workshops, some key challenges were brought to light. For instance, farmers reported limited access to certified seeds as a major barrier to increasing productivity. A farmer from Dodoma expressed concern that current seed distribution networks often do not reach remote areas, leaving farmers with no option but to use inferior seeds from the sources available.
âWe want to use quality seed, but the distribution networks donât reach us,â he said. On the other hand, traders expressed frustration over inconsistent supplies of high-quality grain produce, which is also aggravated by poor grain handling due to inadequate storage conditions leading to contamination.

One groundnut trader noted, âPoor pre- and post-harvest handling has led to smaller, shriveled nuts, making it difficult for traders to meet market expectations.â Processors echoed these concerns, highlighting aflatoxin contamination as a significant problem that undermines both product safety and marketability. They stressed the need for better practices. âWe need better practices at every stage of the value chain to minimize aflatoxin contamination in the grains sourced for processing,â emphasized one processor.
Additional challenges emerged, with common bean farmers highlighting difficulties with post-harvest storage and pest damage, which reduced both quality and market value. Processors, meanwhile, pointed out consumer misconceptions that hinder the acceptance of improved varieties. For instance, white sorghum varieties that naturally turned brown during processing were sometimes perceived as inferior, underscoring the need for better consumer education.
Unveiling Solutions
Despite the challenges, the workshops were a source of optimism, as well as underscoring viable, innovative solutions and actionable strategies to drive progress. Participants explored newly released crop varieties, including TARI Sorg 1 and TARI Bean 6, which offer higher yields, disease resistance, and improved nutritional content. Stakeholders in Dodoma emphasized the use of digital tools such as WhatsApp channels and SMS for real-time updates on seed availability and agronomic practices. âModernizing how we share knowledge can bridge gaps between farmers and researchers,â remarked one participant.
Capacity building emerged as a key strategy for tackling many of the systemic issues discussed. Farmers called for more training on seed handling and post-harvest practices to reduce losses and improve crop quality. Processors stressed the need for targeted interventions for aflatoxin management, a critical step in ensuring the safety and marketability of groundnuts. Researchers and agricultural organizations underscored the importance of aligning breeding programs with market needs.
In Arusha, discussions centered on developing groundnut varieties tailored to specific processing needs, such as improving peanut butter quality to meet consumer preferences and market standards.

Expanding the seed distribution network also emerged as a key priority. TARI committed to scale up the production of Quality Declared Seed (QDS) and strengthen partnerships with private seed companies to ensure a consistent supply of high-quality seeds across the country. âQuality seeds must reach every corner of the country,â affirmed a TARI scientist. The stakeholders also called on breeding programs to align with market demands, emphasizing the need to tailor improved varieties to specific consumer and processor requirements.
Insights from Stakeholders and Actionable Strategies
Breakout sessions provided a platform for stakeholders to articulate their specific needs. Farmers from Dodoma and Dar es Salaam shared a common observation of increasing demand for groundnuts, sorghum, and beans, largely driven by population growth and international market expansion. In Dodoma, farmers emphasized that improved crop varieties had significantly boosted cultivation over the past decade.
Despite this progress, they highlighted the lack of drought-resistant varieties and limited access to affordable, high-quality seeds as persistent challenges. In Dar es Salaam, farmers noted that while demand for the crops had risen, their ability to meet this demand was hampered by limited seed availability and education on effective usage. Both groups agreed that weak seed distribution networks, high seed prices, and insufficient knowledge undermine productivity.

Processors and traders from both Arusha and Dar es Salaam echoed these concerns but added insights into market dynamics. In Arusha, processors identified aflatoxin as a critical challenge, with inadequate farmer knowledge on grain handling practices exacerbating the issue. Processors also emphasized the need for nutrient-enhanced beans and groundnuts suited for specific products like peanut butter and flour. Traders in Arusha highlighted the need for pure white sorghum and beans free from pests to meet growing demand, particularly for export markets.
As the workshops concluded, participants identified key strategies to strengthen agricultural resilience. These included improving the seed supply chains, enhancing market linkages, and investing in continuous learning and education initiatives.
Echoing this vision, the TARI Director General emphasized in Dodoma, âThis is just the beginning. By working together, we can ensure that every farmer, processor, and trader has the tools and knowledge needed to thrive in a rapidly evolving agricultural landscape.â

In Tanzania, the first week of August is all about agriculture. From August 1 to 8, agricultural fairs, also known as Nane Nanefairs, are held all over the country to recognize the contribution of farmers to the national economy. âNane Naneâ in the local language means âeight eight,â referring to August 8, which is celebrated as Farmers Day in the country.
Organized by the Agricultural Society of Tanzania, these fairs serve as a landmark event for agricultural stakeholders across the region. This year, the 31st edition of the fair was organized at the Nzuguni grounds in Dodoma. It saw 500 exhibitors, including smallholder farmers, agricultural enterprises, public and private sector entities, and government officials.
Themed âEmbrace Visionary Leadership for Agricultural Transformation,â the event emphasized the need for leadership commitment to sustainable agriculture, while highlighting the critical role of agriculture in Tanzaniaâs economic growth and food security.
TheSouthern Africa Accelerated Innovation Delivery Initiative (AID-I), funded by United States Agency for International Development (USAID) and implemented by CIMMYT, along with several partners, played a prominent role at this yearâs fair. In addition to raising awareness of the innovative work being done, the fair provided a platform for AID-I and its partners to showcase a range of innovative agricultural technologies designed to address the specific needs of Tanzanian farmers. The event also enabled AID-I and its partners to interact directly with farmers and entrepreneurs, resulting in valuable feedback.Â
Celebrating the Success of AID-I Beneficiaries at Nane Nane
The Nane Nane fair was more than just a display of agricultural technologies. It was also a celebration of the successes of local entrepreneurs who had benefited from AID-I’s support.
Among them was Sarah Mashauri, an entrepreneur from the Tabora region, who ventured into the business world by producing and selling maize flour, both wholesale and retail. Starting with only one sack of maize and a loan of 100,000 Tanzanian shillings (approximately US$36), Sarah faced numerous obstacles, including regulatory challenges that resulted in the Tanzania Food and Drugs Authority confiscating her items. The AID-I project recognized her potential and resilience. She was equipped with a milling and dehulling machine, which significantly improved her business. âBefore the AID-I project came into my life, I was struggling on my own,â she said. âThe support, coupled with the extensive training they provided, enabled me to scale up my operations. I went from employing seven people to 35, and my business expanded significantly. I am now able to source raw materials easily from small-scale farmers, thanks to the networks and training provided by AID-I.â
Agatha Laiza, managing director of Seasoning Palate, a food products company operating under the brand name Tobi Product in Dar es Salaam, is another entrepreneur who benefited from AID-I’s support. Agatha specializes in peanut butter, crunchy nuts, and peanut oil. Her journey began in 1996 with a focus on food product processing. She later realized the potential in peanut production and shifted to adding value to peanuts, while also addressing the critical issue of aflatoxin contamination. With support from AID-I, Agatha was able to build solar dryers for farmers and provide them with high-quality seeds, significantly reducing the risk of aflatoxin in their crops. âThe support from USAID, CIMMYT, and AID-I has been invaluable,â Agatha said. âThey have helped us build confidence among our farmers, reducing ground nut loss and ensuring safe, quality produce. Our factory, which can process up to three tons of peanuts daily, now operates more efficiently and our products are safer and more reliable.â
Aithan Chaula, executive director of the Dodoma Agriculture Seed Production Association (DASPA), also benefited from the AID-I projectâs support. Since beginning pigeon pea production in 2022, DASPA saw substantial growth in demand for pigeon pea seeds, partnering with ALSSEM, a local seed production company.
DASPA expanded its operations to produce quality declared seeds (QDS) and certified seeds, catering to a growing market. Aithan attributed their success to the strategic support from AID-I and partnerships with organizations such as CIMMYT and ALSSEM. âThe collaboration allowed us to expand our production capabilities and reach more farmers across various regions,â he said. DASPA is currently working with approximately 20,000 farmers and plans to increase this number by distributing small seed packs and conducting field demonstrations.
âThis year at Nane Nane, we were able to distribute small packs of pigeon pea seeds to approximately 1,200 farmers to plant and farm,â said Aithan. âThis effort, supported by AID-I, ensures that pigeon pea cultivation becomes well-known and widely adopted by farmers, contributing to both food security and income generation.â

Dr. Michael A. Battle Sr., the United States Ambassador to Tanzania, paid a visit to the AID-I exhibition booth. He engaged with AID-I representatives and the exhibitors, praising their innovative efforts to advance climate-smart agriculture and enhance food security. âIt’s a joy to be participating in Nane Nane, particularly because USAID is interested in assisting Tanzania not only to become food secure but also to help with East Africaâs food security and ultimately the continentâs food security,â said Ambassador Battle Sr. He added that it was fulfilling to see the entire value chain of agriculture and agribusiness involving young people and old people engaged in the process of making Tanzania wealthier and more food secure.
For AID-I and its partners, the fair was a crucial opportunity to highlight ongoing initiatives and foster new partnerships. Peter Setimela, the Legume Seed Systems lead for AID-I, emphasized the importance of such events. âOur work in accelerating innovative technologies and ensuring they reach the farmers is reliant on strong partnerships. We bring these technologies to farmers by strengthening local seed systems, connecting farmers to financial services and products, and providing advisory services,â he said.

With the support of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, ADP Mbozi, and the Tanzania Agricultural Research Institute (TARI) at Uyole (key implementing partners in the Southern Highland Consortium), the Songwe region of Tanzania is setting for a pivotal initiative to enhance crop yields significantly.
In anticipation of the forthcoming Mega Demo and Mother Demo planting events, the AID-I partners orchestrated workshops and training sessions for local farmers.
This multifaceted endeavor involves both comprehensive soil testing and an educational campaign aimed at enlightening farmers on the proper use of fertilizers, aligning their application with the specific requirements of cultivated crops.
The Songwe region is in the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) and is a breadbasket region of Tanzania.
Soil testing offers farmers invaluable insights for informed decision-making concerning fertilizer application. Armed with knowledge about their soil’s nutrient status, farmers can precisely tailor fertilizer usage, steering clear of both excessive and insufficient application. The adverse effects of over-application, such as environmental pollution and crop damage, and the consequences of under-application, leading to nutrient deficiencies and stunted crop growth, are mitigated.
These sessions fostered participation and equipped farmers with an enhanced understanding of the intricate relationship between soil nutrients, fertilizer application, crop nutrition, plant development, and management for improved crop productivity.
The Alliance for Green Revolution in Africa (AGRA), through its implementing partners, conducted soil tests at 235 sites in 2023 within the Southern Highland and Western Great Lakes consortia. The consolidated results of soil tests and recommendations were disseminated to government officials and agricultural extension agents in wards and villages for informed decisions to improve the status of soil health. Â The resulting data is distributed to farmers to help inform their decision-making around the type and variety of fertilizer to use.
The active involvement of farmers in soil testing and awareness initiatives underscores their recognition of the potential benefits for their livelihoods. Armed with newfound knowledge, farmers are now empowered to make informed decisions regarding fertilizer use, ensuring an optimal nutrient balance for their crops and maximizing productivity. Young farmers from the area also participated in activities from mapping to collection of soil samples in different villages, with a clear vision of conducting soil testing with the goal of mitigating climate change.
âThe proactive stance of the Songwe region towards soil testing and fertilizer awareness reflects a steadfast commitment to sustainable agriculture and farmer empowerment,â said Project Officer ADP MBOZI, Edward Mwakagile. âBy providing farmers with the knowledge and tools to manage their soil and fertilizer use effectively, the region is laying a robust foundation for successful Mega Demo and Mother Demo planting events, promising enhanced agricultural productivity in the years ahead.â
Joseph Gambi began as a groundnut seed producer in Ukwile village, Mbozi District, Songwe, Tanzania. He struggled to make a living from agriculture, an experience shared by many young people and women in his village. Low yields, limited opportunities in agricultural value chains, and low productivity in current production systems meant that there were fewer opportunities for income generation, which all negatively impacted the involvement of youth and women.
Based on his experience as a young farmer, Joseph believed groundnut farming could be more profitable than maize. “Although groundnut farming is promising and earns good money, its productivity is very low. Most of us opt for maize because quality seeds and other inputs are available, despite its high capital needs,” said Joseph.
To improve the situation, CIMMYTâs Dryland Crops Program aims to increase the adoption of quality seeds among youth and women farmers through behavior change interventions. Led by CIMMYT and implemented in partnership with the Center for Behaviour Change and Communication (CBCC) and the Tanzania Agricultural Research Institute (TARI), the project targets sorghum and groundnut improvement in Tanzania’s Songwe region.
Joseph was selected by his community to lead the way in changing perceptions of groundnut in his village and trained as a last-mile change agent, equipped with knowledge on social behavior change. As a youth champion and seed producer in Ukwile village, he has created awareness about quality seeds and good farming practices among at least 600 farmers across more than 15 villages in the district.

Seed demand creation
Through the Drylands Crop Program, Joseph has been trained in various awareness and demand creation strategies, such as farmer mobilization. He uses these skills to raise farmersâ interest in different technologies and products, creating demand for various agricultural inputs and seeking out suppliers.
His efforts have attracted a variety of stakeholders to his village. These include four TARI centers, five seed companies, three non-government organizations (NGOs), one agrodealer, and two off-takers. While most stakeholders partner with him to demonstrate and promote their technologies to the farmers he has mobilized, others enter into agreements and pay him a commission for each sale he facilitates.
In the first season, Joseph created demand for more than two tons of groundnut seed, partnering with Pavig Agro, a groundnut seed company, to distribute almost 1.2 tons of quality seed to farmers in his village. The seed company could not adequately meet the aggregated demand, creating an opportunity for Joseph and 17 others to train as Quality Declared Seeds (QDS) producers.
Dedicated support for youth and women
After creating traction for quality seeds, inputs, and other agricultural services, the project established the Youth and Women Quality Center (YWQC) in Ukwile, managed by Joseph and three other community champions. The center serves more than 1,000 farmers across five villages and currently hosts more than ten demonstration plots featuring nine varieties of groundnut, maize, five bean varieties, and sorghum.
Furthermore, the center is now registered and licensed to distribute seeds and offers services such as seed planting using a manually operated seed planter, pesticide and herbicide spraying, extension support, market information, farmersâ advisory services, input demand creation and distribution, and produce aggregation.

The project has proved to be transformational for Joseph, who has now received certification as a seed producer and dealer, as well as for his family and wider community. Before the training, Joseph allocated half an acre for groundnut production each season; he now uses three acres, with an additional acre for sorghum seed and a further half acre for bean seed production.
He has also mobilized and supported the registration of ten farmer groups, three of which were trained as seed producers and now produce groundnut seed and mentored five youths and women to become seed producers. This work means that the Ukwile YWQC now has 12 seed producers cultivating 13.5 acres of groundnut seed. Joseph and other experienced seed producers multiply basic seed to produce QDS 1, which is then sold to other seed producers at affordable prices.
Thanks to Joseph’s awareness and demand creation initiatives, Ukwile YWQC generated US $4,000 in revenue from seed and input distribution between November 2022 and January 2024. From two acres alone of groundnut seed production, Joseph earned US $1,456 from selling groundnut QDS between December 2023 and January 2024.
His increased income has supported his family, including paying for education for his four children, and has purchased a plot of land, on which he is constructing a three-bedroom house.

The Songwe Region in Tanzania faces a variety of challenges in its agricultural communities, including low productivity, poor farming practices, and limited access to resources. Low yields from white sorghum, the crop of preference in the area, contribute to food insecurity, and insufficient extension support compounds the challenges for farmers.
Schools in the region face their own problems, with students experiencing a lack of food during certain months, resulting in poor academic performance and attendance. Parents, burdened by financial constraints and the low yields of sorghum, struggle to contribute to the school feeding program, further aggravating the situation. The School Feeding Program provides at least one nutritious meal daily to students in rural Tanzania to combat hunger and enhance academic performance. Most schools in rural areas have enough farmland for learning purposes; by utilizing this land, the program aims to produce food locally, reducing reliance on parental contributions and involving the community in addressing food and nutrition insecurity.
To address these challenges, the Center for Behavior Change and Communication (CBCC), initiated a proactive intervention during the 2022-2023 farming season to increase awareness of improved sorghum seed varieties (TARI SOR 1 and TARI SOR 2) through the school feeding program in Momba district, Tanzania. This collaborative effort between the Tanzania Agricultural Research Institute (TARI), CIMMYT, local seed producers, and the local government aimed to address the persistent food and nutrition insecurity in the area.

One of the key strategies employed by CBCC was using schools as platforms for raising awareness. Schools primarily grow sorghum for food rather than trade, making them ideal places to introduce these new, higher-yielding, and nutritionally valuable seed varieties.
Leveraging school farmland
The Youth and Women Quality Centres (YWQCs) are part of an innovative model implemented through the Dryland Crops Program (DCP) through the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project, led by CIMMYT and implemented in partnership with CBCC and TARI. Its goal is to increase the adoption of improved variety and quality seeds among young and female farmers through behavior change interventions, with a focus on sorghum and groundnut improvement in the Songwe Region.
Using schools as focal points for raising awareness, the initiative leveraged the YWQCs to provide extension support and distribute seeds to schools. Training materials tailored to the school environment facilitated practical learning on agronomic practices such as farm preparation, seed selection, planting, fertilizer application, weeding, and pest management.
Mkama Secondary School was one of the first to enroll in the program, setting aside 0.5 acres to demonstrate the performance of TARI sorghum seed varieties. With the use of good agronomic practices, the pilot led to an increase in yield, with 350 kilograms (kg) of sorghum harvested. This was an increased improvement compared to their previous yield of 200 kg per acre on their four-acre farm, representing an increase of approximately 75%.
Concerns raised by teachers about the limited yield of local seeds, yielding less than 200 kg per acre, necessitate the urgency of implementing sustainable solutions. The low productivity observed on school farms is also attributed to poor farming practices and inadequate extension support.
Growing these new varieties offers many practical benefits. The increased yield enabled the school to provide lunch to its 129 students during the critical period when food insecurity is most pronounced (October-April). “The new improved sorghum varieties have higher yields, and TARI SOR 2 makes good Ugali,” said Johnas Marwa, the school headmaster. Motivated by their success, the school will plant TARI SOR 1 and TARI SOR 2 on all four acres of their farm during the 2023-2024 season.
Community-wide benefits
The projectâs success also inspired confidence in the broader community, leading to a surge in demand for the new sorghum seeds. Consequently, eight seed producer groups and five individual seed producers decided to cultivate these improved varieties in the coming season.
Initially, some community members were hesitant to adopt the new varieties because they were not as white as the traditional local seeds. However, the impressive performance of TARI SOR 1 and TARI SOR 2 quickly won them over, capturing the attention of both farmers and parents due to their potential to reduce food insecurity at household level.
The achievements at Mkama Secondary School led to the expansion of the initiative across 19 additional schools in 14 villages. These schools were chosen based on their willingness to participate and the availability of their farmland. Out of the schools involved, only five produced sorghum on their farms, with the rest relying on parental contributions for the feeding program, but they all relied upon sorghum as the main source of food. Some primary schools only provided porridge, while most of the secondary schools only offered lunch.
Across the 19 schools, a total of 58 acres were allocated for farming sorghum. The project provided 190 kg of seeds, 21% of which were the Macia variety, a popular choice because of its whitish appearance and marketability.
Emmanuel Mwenda, national sorghum coordinator at TARI, said, “This intervention is one of a kind and will bring a huge impact to farmer communities in Momba district.”
Project legacy
The initiative has already had a significant impact and will continue to do so for future planting seasons and generations. “Given the level of effort and investment by partners, in the next season, 4 out of 10 farmers purchasing improved seed at YWQCs will choose either TARI SOR 1 or 2,” said Michel Amson from CBCC.
More than 2,000 students and 50 teachers were trained in agronomic practices by dedicated youth champions. This training caused a ripple effect, with parents visiting YWQC to purchase quality seeds too for growing on their own land.
To ensure the projectâs sustainability and longevity, education officers will work with more schools and YWQCs would provide seeds on credit, with schools repaying after harvest to make the improved varieties more accessible when they are needed most.
âThis initiative not only improves nutrition and food security for school children, but also benefits the wider community by increasing yields and extending meal provision periods. The collaborative efforts of various stakeholders have been instrumental in driving the success of this initiativeâ, says Chris Ojiewo, seeds systems lead at CIMMYT.
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.
One of the worldâs largest crop pathogen surveillance systems is set to expand its analytic and knowledge systems capacity to protect wheat productivity in food vulnerable areas of East Africa and South Asia.
Researchers announced the Wheat Disease Early Warning Advisory System (Wheat DEWAS), funded through a $7.3 million grant from the Bill & Melinda Gates Foundation and the United Kingdomâs Foreign, Commonwealth & Development Office, to enhance crop resilience to wheat diseases.
The project is led by David Hodson, principal scientist at CIMMYT, and Maricelis Acevedo, research professor of global development and plant pathology at Cornell Universityâs College of Agriculture and Life Sciences. This initiative brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.
Wheat DEWAS aims to be an open and scalable system capable of tracking important pathogen strains. The system builds on existing capabilities developed by the research team to provide near-real-time model-based risk forecasts and resulting in accurate, timely and actionable advice to farmers. As plant pathogens continue to evolve and threaten global food production, the system strengthens the capacity of countries to respond in a proactive manner to transboundary wheat diseases.
The system focuses on the two major fungal pathogens of wheat known as rust and blast diseases. Rust diseases, named for a rust-like appearance on infected plants, are hyper-variable and can significantly reduce crop yields when they attack. The fungus releases trillions of spores that can ride wind currents across national borders and continents and spread devastating epidemics quickly over vast areas.
Wheat blast, caused by the fungus Magnaporte oryzae Tritici, is an increasing threat to wheat production, following detection in both Bangladesh and Zambia. The fungus spreads over short distances and through the planting of infected seeds. Grains of infected plants shrivel within a week of first symptoms, providing little time for farmers to take preventative actions. Most wheat grown in the world has limited resistance to wheat blast.
âNew wheat pathogen variants are constantly evolving and are spreading rapidly on a global scale,â said Hodson, principal investigator for Wheat DEWAS. âComplete crop losses in some of the most food vulnerable areas of the world are possible under favorable epidemiological conditions. Vigilance coupled with pathogen-informed breeding strategies are essential to prevent wheat disease epidemics. Improved monitoring, early warning and advisory approaches are an important component for safeguarding food supplies.â
Previous long-term investments in rust pathogen surveillance, modelling, and diagnostics built one of the largest operational global surveillance and monitoring system for any crop disease. The research permitted the development of functioning prototypes of advanced early warning advisory systems (EWAS) in East Africa and South Asia. Wheat DEWAS seeks to improve on that foundation to build a scalable, integrated, and sustainable solution that can provide improved advanced timely warning of vulnerability to emerging and migrating wheat diseases.
âThe impact of these diseases is greatest on small-scale producers, negatively affecting livelihoods, income, and food security,â Acevedo said. âUltimately, with this project we aim to maximize opportunities for smallholder farmers to benefit from hyper-local analytic and knowledge systems to protect wheat productivity.â
The system has already proven successful, contributing to prevention of a potential rust outbreak in Ethiopia in 2021. At that time, the early warning and global monitoring detected a new yellow rust strain with high epidemic potential. Risk mapping and real-time early forecasting identified the risk and allowed a timely and effective response by farmers and officials. That growing season ended up being a production record-breaker for Ethiopian wheat farmers.
While wheat is the major focus of the system, pathogens with similar biology and dispersal modes exist for all major crops. Discoveries made in the wheat system could provide essential infrastructure, methods for data collection and analysis to aid interventions that will be relevant to other crops.
The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the worldâs largest and most advanced crop pathogen surveillance systems. With Wheat DEWAS, researchers are building an open and scalable system capable of preventing disease outbreaks from novel pathogen strains that threaten wheat productivity in food vulnerable areas of East Africa and South Asia.
The system builds from capabilities developed previously by multi-institutional research teams funded through long-term investments in rust pathogen surveillance, modelling, and diagnostics. Once fully operationalized, the project aims to provide near-real-time, model-based risk forecasts for governments. The result: accurate, timely and actionable advice for farmers to respond proactively to migrating wheat diseases.
The Challenge
Farmers growing wheat face pathogen pressures from a range of sources. Two of the most damaging are the fungal diseases known as rust and blast. Rust is a chronic issue for farmers in all parts of the world. A study in 2015 estimated that the three rust diseases â stem, stripe and leaf â destroyed more than 15 million tons of wheat at a cost of nearly $3 billion worldwide. Wheat blast is an increasing threat to wheat production and has been detected in both Bangladesh and Zambia. Each of these diseases can destroy entire harvests without warning, wiping out critical income and food security for resource-poor farmers in vulnerable areas.
The Response
Weather forecasts and early-warning alerts are modern technologies that people rely on for actionable information in the case of severe weather. Now imagine a system that lets farmers know in advance when dangerous conditions will threaten their crop in the field. Wheat DEWAS aims to do just that through a scalable, integrated, and sustainable global surveillance and monitoring system for wheat.
Wheat DEWAS brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

The formation of regional crop improvement networks took center stage at a meeting held in January 2023 in Accra, Ghana. The meeting convened more than 200 scientists and stakeholders in dryland crops value chains from 28 countries from Africa and across the globe to co-design a network approach.
The meeting followed a series of consultative visits and discussions between three CGIAR research centers â the International Maize and Wheat Improvement Center (CIMMYT), Alliance of Bioversity International and CIAT, and the International Institute of Tropical Agriculture (IITA) â African National Agricultural Research Institutes (NARIs), and other common-visioned partners during 2021 and 2022. These earlier discussions gathered insights, brainstormed, and co-designed approaches to empower national programs to deliver impact through their crop improvement programs.
âThe idea is to add value to the existing capacities in National Agricultural Research and Extension Services, through networks where the partners agree on the goals and resources needed to achieve desired outcomes. So, itâs really a collaborative model,â said Harish Gandhi, breeding lead for dryland legumes and cereals at CIMMYT. He added that the teams have been learning from and aiming to add value to existing models such as the Pan-Africa Bean Research Alliance (PABRA), USAID Innovation Labs, and Innovation and plant breeding in West Africa (IAVAO).
Paradigm shift for African National Agricultural Research Institutes
Making the opening remarks, Ghana Council for Scientific and Industrial Research (CSIR) Director General, Paul Bosu said that at the very least, African countries should aim to feed themselves and transition from net importers to net exporters of food. âDryland legumes and cereals, especially millet and sorghum, are very well adapted to the continent and offer great opportunity towards achieving food securityâ, said Bosu. He applauded the Bill & Melinda Gates Foundation and other partners for investing in research on these crops.
Representing West and Central African Council for Agricultural Research and Development (CORAF), Ousmane Ndoye noted that research in dryland legumes and cereals is a valid and needed action amidst the COVID-19 pandemic and civil unrest in different parts of the world. He added that the first and crucial step to increasing food production especially in sub-Saharan Africa is the availability of sufficient quantities of seed.
Director General of Ugandaâs National Agriculture Research Organization (NARO), Ambrose Agona observed that a paradigm shift should occur for desired transformation in agriculture. He noted that African governments ought to commit adequate budgets to agriculture and that seed funding should serve to complement and amplify existing national budgets for sustainability.
He commended efforts to consult NARIs in Africa and noted that the quality of ideas exchanged at the meeting strengthen the work. âThe NARIs feel happier when they are consulted from the very beginning and contribute to joint planning unlike in some cases where the NARIs in Africa are only called upon to make budgets and are excluded from co-designing projectsâ, said Agona.

Challenge to deliver effectively
During his remarks at the meeting, CIMMYT Director General Bram Govaerts noted that the focus legume and cereal crops are key to transforming and driving diversification of food systems in Africa. âIt is therefore an honor and a privilege to work together with partners to improve cereal and legume systems. We will put forward our experience in breeding and commit to innovative systems approaches towards achieving impact and leverage what we are already good at, to become even better,â said Govaerts.
Referencing his visit with the United States Special Envoy for Global Food Security Cary Fowler to Southern Africa in January 2023, Govaerts narrated witnessing firsthand a food, energy and fertilizer crisis impacting Zambian and Malawian farmers. He challenged the meeting participants to envision the future impact they would like to see their breeding programs have as they design and strategize at the meeting. He pointed out that farmers are more interested in the qualities and characteristics of varieties released than the institutions responsible for the release.
CIMMYT Global Genetic Resources Director and Deputy Director General, Breeding and Genetics, Kevin Pixley also underscored the need to generate more impact through adoption of improved varieties in Africa. Pixley noted that on average, fewer than 30 percent of farmers are using improved varieties of sorghum, millet, and groundnut across the countries with ongoing work.
The meeting heard One CGIARâs commitment to deliver resilient, nutritious and market preferred varieties as part of its Genetic Innovation Action Area, alongside improving systems and processes for sustainability from CGIAR Senior Director Plant Breeding and Pre-Breeding, John Derera. Speaking in the capacity of IITAâs Breeding Lead, Derera noted the progress made in IITA cowpea breeding program, including its modernization, owing to strong partnerships, cross learning and germplasm exchange between institutions.
PABRA Director & Leader of the Bean Programme at the Alliance of Bioversity International and CIAT, Jean-Claude Rubyogo, pointed out that despite remarkable achievements, such as those witnessed in the bean research, more effort is needed to tackle the challenges of climate change and also increase understanding of consumers traits.
Commenting on innovative pathways to improve adoption of improved varieties, the Director General of the Institute of Agricultural Research (IAR) in Zaria, Nigeria, Mohammad Ishiyaku observed the tendency for some seed companies to continue selling specific seed varieties for years, even when the productivity of the variety is low. He noted the seed companies always claimed consumer preferences concluding then that amidst investor demands, breeders ought to keenly investigate the expectations of consumers and famers to arrive at the best parameters for breeding choices.

High-level statements on approaches to gender integration in agricultural research and development were delivered by Scovia Adikini, NARO millet breeder, Geoffrey Mkamillo, Director General of Tanzaniaâs Agricultural Research Institute (TARI), Francis Kusi of Ghanaâs Savanna Agricultural Research Institute (SARI), and Aliou Faye, Director of Senegalâs Regional Center of Excellence on Dry Cereals and Associated Crops (CERAAS).
AVISA Achievements
Finally, this meeting marked the transition from the recently ended Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project to align with One CGIAR initiatives under the Genetic Innovation Action Area, with specific focus on dryland crops.
Solomon Gyan Ansah, the Director of Crop Services at the Ministry of Food and Agriculture, Ghana, acknowledged the success of AVISA Project and commended the forumâs efforts to build on the gains made by the project in developing the new approach.
âBy the end of 2022, AVISA project partners had reached 4.8 million farmers with 30,600 metric tons of seed of improved legume and cereal varieties, covering almost one million hectares of landâ, revealed Chris Ojiewo, Strategic Partnerships and Seeds Systems Lead. Other achievements supported by the AVISA Project include upgrading of NARES facilities and building capacities of researchers through short- and long-term trainings.
The meeting was hosted by Ghana Council for Scientific and Industrial Research (CSIR) and Ghanaâs Savannah Agricultural Research Institute (SARI), and was organized by CIMMYT, in partnership with IITA and the Alliance of Bioversity and CIAT (ABC).
Happy Makuru Daudi, Head of Groundnut Research Program at the Tanzania Agricultural Research Institute (TARI) based at Naliendele Research Center in Mtwara, is a plant breeder specializing in groundnut. For the United Nations International Day of Women and Girls in Science, she shares with us her passion for what she does and why more women should venture into plant breeding.
What inspired you to get into your career?
I was in love with science and my intention was to be a doctor but later I changed my mind. I loved biology a lot and that set my focus on my academic path. At university I had good mentors who influenced my career direction as well.
When I achieved my first degree, I was recruited by the Government of Tanzania as an agricultural officer. My then boss, Omar Mponda, inspired me to be a plant breeder. He encouraged me and I went ahead to study plant breeding for both my Masters and PhD. My first degree was in Agronomy, I then did a Masters in Crop Science, specializing in Plant Breeding, and eventually completed a PhD in Plant Breeding as well.
What did you love about plant breeding?
I realized breeders are very active people. Always trying to improve and change things. Always looking for ways to make a difference. This desire to make a change makes us active lifelong learners.
The other thing I learnt from breeders is that they can change the life of farmers. Most smallholder farmers are women. I love my crop (groundnut) because it is a âwomanâs cropâ. If the breeder develops a product such as groundnut with high impact, it means they have changed the life of women. I realized I work a lot with women in my field and even if I only change the smallest of things, it means I get to change their lives and boost them from one step to the next.
Please elaborate on why you refer to groundnut as a womanâs crop.
Groundnut is a nutritious crop and is used a lot in processing and preparing childrenâs food, hence most women value it and engage in farming the crop, even though in small plots of land, in order to have nutritious food for their familiesâ health.
Most women especially in Tanzania view groundnut as their ATM, in that when they need money for use at home, they only need to sell some of their harvested groundnut and get cash to meet their homeâs needs, such as buying schoolbooks for their children.
Women are involved in the entire groundnut value chain, that is from farming the crop in the field up to the processing stages, unlike men who mostly only come in at the market stage to sell the produce. Therefore, groundnut is source of income for many women in Tanzania.

Has the International Maize and Wheat Center (CIMMYT) and the CGIAR at large contributed in any way to your career growth?
Yes! They have contributed a lot. First in building my capacity and, as I work with them in the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project. My PhD was sponsored by the Tropical Legumes III Project. I remember when interacting with scientists from these organizations, I observed how they carried themselves with confidence, both the women and men; it motivated me and built my confidence.
What was the focus of your PhD?
My PhD was on breeding for groundnut resistance for rust and high yield in Tanzania.
What is your message for young women and girls interested in getting into science, technology, engineering, and mathematics (STEM) careers?
First, they need to trust themselves. They can do anything in this world. They should not be fearful. For instance, those interested in breeding might observe that most breeders are men, and they may tell themselves that it is a difficult career and run away from it. But I would like them to tell themselves they can be and do even better than men. They only need to trust themselves and build their confidence.
Tell me about the formation of your team – are you intentional in working with women in your team?
Yes, Iâm usually intentional about this. I always give equal chance to both genders but when I get an opportunity to hire for my team, it makes me happier if a woman lands the job. I realized women are good workers and ready to learn. Most of my casual laborers on my team are also women. They work meticulously. The main work for breeders entails crossing. The best people for crossing are women! I have observed that the success rate of the crosses is higher with women! Crossing is intensive work, physically as well, and needs utmost concentration. So, I trust them in this.
Is there anything else you would like to add?
I want to encourage women not to run away from sciences, and especially agricultural sciences such as breeding. We want more women breeders. They can change this world and help more people put food on the table. The agricultural sector, especially the farms, are dominated by women, and it is easier for them when they interact with other women. When we go meet them in the fields, it is easier for us to understand their needs and change their lives. So, I call girls and women to come on board in this sector and change the lives of many.

The Accelerated Varietal Improvement and Seed Delivery of Legumes and Cereals in Africa (AVISA) project has developed draft national groundnut target product profiles in Malawi, Mozambique, Sudan, Tanzania, Uganda and Zambia.
Groundnut is grown in eastern and southern Africa, where it remains an important food and oil crop from small holder farmers.
The new findings from the project are a result of work from groundnut crop breeding and improvement teams from the National Agricultural Research and Extension Systems (NARES) representatives from the six largest groundnut producing countries in the eastern and southern Africa region.
Their important research was carried out with the support of representatives from the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) and CGIAR.
Developing target product profiles for groundnut
For the first time, through the International Maize and Wheat Improvement Center (CIMMYT)-led AVISA program, funded by the Bill & Melinda Gates Foundation, groundnut breeding teams discussed and documented country level priorities at a meeting in Dar es Salaam, Tanzania.
The groundnut breeding teams also shared information on current groundnut production metrics and trends in the six national programs. This also helped to establish a common understanding of countriesâ level research priorities.

Agnes Gitonga, market strategist at CGIAR Genetic Innovations Action Area, who led the team in understanding and applying the template, explained that the quality of a target product profile (TPP) is dependent on how well market segments are defined. âTo ensure target product profiles are an accurate reflection of customer needs, who include farmers, consumers, and processors,â she said.
âNational groundnut teams nominated Country Product Design Teams that will meet nationally before the end of 2022 to review and update country TPPs. These multi-stakeholder teams will ensure that the needs of diverse groups are captured and that breeding efforts are accurately focused.â.
Harish Gandhi, Breeding Lead, Dryland Legumes and Cereals (DLC) at CIMMYT, further explained that a bottom-up approach for defining country and regional priorities was used, where each country defined market segments and target product profile based on the use of the produce and growing conditions of farmers. This strategy involved each country defining its market segments and TPP, which was based on the use of the produce and growing conditions of farmers.
Building on the draft national target product profiles that were defined at the meeting, participants went on to prioritize traits such as diseases, nutrition and stress tolerance. These factors can be critical at regional level and important in identifying potential locations for conducting phenotyping. The phenotyping locations are distributed based on capacity of stations in different countries to screen for traits, such as late leaf spot disease screening in Msekera in Zambia, which is a known hotspot for the disease.
âWe had a good opportunity to consider grower needs as well as consumer needs in each country for purposes of defining the relevant groundnuts market segments. I believe this will have a positive impact on future work in groundnuts in the East and Southern Africa region,â reflected Gitonga.
The collaboration of the teams involved was a key factor for the projectâs success so far and will be crucial in working towards its goals in the future.
âInvolving different stakeholders in designing target product profile was an effective way of enabling transformation of individual preferences (area of interest) to collective preferences (targeted product) with consumer needs and markets in mind,â said Happy Daudi, Groundnut Breeding lead at the Tanzania Agricultural Research Institute (TARI).

Strengthening groundnut breeding programs in east and southern Africa
The projectâs first meeting will provide an important foundation for future research, which will use the new findings as a blueprint.
Biswanath Das, Plant Breeder, Groundnut for East and Southern Africa region and NARES Coordinator and Programming lead for EiB said, âDefining national TPPs, identifying regionally important traits and mapping a testing network are fundamental building blocks of a modern breeding program.â
At the meeting, a schedule was laid out for peer-to-peer assessments of breeding programs within the regional network to take stock of current efforts and gaps. This step helps to develop customized capacity development plans for each network partner.
âThrough targeted and demand led capacity development, the East and Southern Africa groundnut crop improvement network aspires to strengthen the role of each network member in collaborative, regional breeding efforts,â Das said.
The meeting laid the ground for coordinated regional groundnut breeding and took steps towards formalizing a regional NARES-CGIAR-SME groundnut crop improvement network. By building on excellent connections that already exist among national groundnut breeding teams. Das underscored that the move will strengthen alignment of NARES, CGIAR and regional research efforts around a common vision of success.
In addition, David Okello who leads groundnut research at National Agriculture Research Organization (NARO) Uganda, noted that the meeting provided a good opportunity for consolidating the existing network. He also looked forward to welcoming more groundnut improvement programs in the region on board.
Dryland Crops, formerly known as the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project, aims to improve the livelihoods of small-scale producers and consumers of sorghum, millet, groundnut, cowpea and bean. Project partners focus on improving the breeding and seed systems of these crops in their key geographies in Burkina Faso, Ethiopia, Ghana, Mali, Nigeria, Tanzania and Uganda. Other crops receiving growing attention in the project include finger millet, pigeon pea and chickpea.
Although significant adoption of improved seed of dryland cereals and legume crops in Africa has been reported, its overall use remains low. There is a growing interest in these crops, particularly because of their resilience to climate-change; however, the seed sector is constrained by lack of product information, dearth of knowledge of the size and scale of the business opportunity, and inadequate access to early generation seed.
Dryland Crops will address these constraints by contributing to the establishment of robust systems that:
Enable networks to work synergistically across countries with common challenges and opportunities.
Support national agricultural research systems to access research, professional development and infrastructure-building opportunities.
Increase the quantity and quality of data substantiating varietal superiority and the demand for seed and grain of improved varieties.
Boost the availability of early generation seed and strengthen links between the research system and private- and public-sector actors.
The aspiration is to codevelop, validate by co-implementation, and continuously improve with partners research-to-farm-to-consumer models that achieve positive impacts on farmersâ livelihoods and consumersâ wellbeing.
The Alliance of Bioversity and CIAT and IITA will lead initiatives for common bean and cowpea, respectively. For sorghum, pearl millet and groundnut breeding, CIMMYT will design programs that support crop improvement networks, including CGIAR and national agricultural research systems, and incorporate best approaches, principles, and tools, particularly those availed through the Excellence in Breeding (EiB) platform.
The project is committed to gender equity as a guiding principle, considering the critical role women play in choosing legume and cereal varieties and seed sources. Women seed entrepreneurs and women-led seed companies will garner special attention for capacity development. Partnerships with actors through the value chain, platforms and demonstrations will ensure women have equal access to improved technologies.
The previous phase of the AVISA project was led by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).
The food security and livelihoods of smallholder farming families in sub-Saharan Africa depend on maize production. The region accounts for up to two-thirds of global maize production, but is facing challenges related to extreme weather events, climate-induced stresses, pests and diseases, and deteriorating soil quality. These require swift interventions and innovations to safeguard maize yields and quality.
In this Q&A, we reflect on the results and impact of the long-term collaborative work on drought-tolerant maize innovations spearheaded by two CGIAR Research Centers: the International Maize and Wheat Improvement Center (CIMMYT) and International Institute of Tropical Agriculture (IITA). This innovative work has changed guises over the years, from the early work of the Drought Tolerant Maize for Africa (DTMA) and Drought Tolerant Maize for Africa Seed Scaling (DTMASS) projects through later iterations such as Stress Tolerant Maize for Africa (STMA) and the newest project, Accelerating Genetic Gains in Maize and Wheat (AGG).
In this Q&A, three leaders of this collaborative research reflect on the challenges their work has faced, the innovations and impact it has generated for smallholder farmers, and possible directions for future research. They are: B.M Prasanna, director of CIMMYTâs Global Maize Program and of the CGIAR Research Program on Maize (MAIZE); Abebe Menkir, a maize breeder and maize improvement lead at IITA; and Cosmos Magorokosho, project lead for AGG-Maize at CIMMYT.
Briefly describe the challenges confronting small-scale farmers prior to the introduction of drought-tolerant maize and how CIMMYT and IITA responded to these challenges?
B.M.P.: Maize is grown on over 38 million hectares in sub-Saharan Africa, accounting for 40% of cereal production in the region and providing at least 30% of the populationâs total calorie intake. The crop is predominantly grown under rainfed conditions by resource-constrained smallholder farmers who often face erratic rainfall, poor soil fertility, increasing incidence of climatic extremes â especially drought and heat â and the threat of devastating diseases and insect pests.
Around 40% of maize-growing areas in sub-Saharan Africa face occasional drought stress with a yield loss of 10â25%. An additional 25% of the maize crop suffers frequent drought, with yield losses of up to 50%. Climate change is further exacerbating the situation, with devastating effects on the food security and livelihoods of the millions of smallholder farmers and their families who depend on maize in sub-Saharan Africa. Therefore, the improved maize varieties with drought tolerance, disease resistance and other farmer-preferred traits developed and deployed by CIMMYT and IITA over the last ten years in partnership with an array of national partners and seed companies across sub-Saharan Africa are critical in effectively tackling this major challenge.
A.M.: Consumption of maize as food varies considerably across sub-Saharan Africa, exceeding 100 kg per capita per year in many countries in southern Africa. In years when rainfall is adequate, virtually all maize consumed for food is grown in sub-Saharan Africa, with a minimal dependence on imported grain. Maize production, however, is highly variable from year to year due to the occurrence of drought and the dependence of national maize yields on seasonal rainfall. One consequence has been widespread famine occurring every five to ten years in sub-Saharan Africa, accompanied by large volumes of imported maize grain as food aid or direct imports.
This places a significant strain on resources of the World Food Programme and on national foreign exchange. It also disincentivizes local food production and may not prevent or address cyclical famine. It also leaves countries ill-equipped to address famine conditions in the period between the onset of the crisis and the arrival of food aid. Investment in local production, which would strengthen the resilience and self-sufficiency in food production of smallholder farming families, is a far better option to mitigate food shortages than relying on food aid and grain imports.
C.M.: Smallholder farmers in sub-Saharan Africa face innumerable natural and socioeconomic constraints. CIMMYT, in partnership with IITA and national agricultural research system partners, responded by developing and catalyzing the commercialization of new maize varieties that produce reasonable maize yields under unpredictable rainfall-dependent growing season.
Over the life of the partnership, more than 300 new climate-adaptive maize varieties were developed and released in more than 20 countries across sub-Saharan Africa where maize is a major staple food crop. Certified seed of over 100 stress-tolerant improved maize varieties have been produced by seed company partners, reaching more than 110,000 tons in 2019. The seeds of these drought-tolerant maize varieties have benefited more than 8 million households and were estimated to be grown on more than 5 million hectares in eastern, southern and west Africa in 2020.

In what ways did the drought-tolerant maize innovation transform small-scale farmersâ ability to respond to climate-induced risks? Are there any additional impacts on small scale farmers in addition to climate adaptation?
B.M.P.: The elite drought-tolerant maize varieties can not only provide increased yield in drought-stressed crop seasons, they also offer much needed yield stability. This means better performance than non-drought-tolerant varieties in both good years and bad years to a smallholder farmer.
Drought-tolerant maize varieties developed by CIMMYT and IITA demonstrate at least 25-30% grain yield advantage over non-drought-tolerant maize varieties in sub-Saharan Africa under drought stress at flowering. This translates into at least a 1 ton per hectare enhanced grain yield on average, as well as reduced downside risk in terms of lost income, food insecurity and other risks associated with crop yield variability. In addition to climate adaptation, smallholder farmers benefit from these varieties due to improved resistance to major diseases like maize lethal necrosis and parasitic weeds like Striga. We have also developed drought-tolerant maize varieties with enhanced protein quality â such as Quality Protein Maize or QPM â and provitamin A, which improve nutritional outcomes.
We must also note that drought risk in sub-Saharan Africa has multiple and far-reaching consequences. It reduces incentives for smallholder farmers to intensify maize-based systems and for commercial seed companies to invest and evolve due to a limited seed market.
Drought-tolerant maize is, therefore, a game changer as it reduces the downside risk for both farmers and seed companies and increases demand for improved maize seed, thus strengthening the commercial seed market in sub-Saharan Africa. Extensive public-private partnerships around drought-tolerant maize varieties supported the nascent seed sector in sub-Saharan Africa and has enabled maize-based seed companies to significantly grow over the last decade. Seed companies in turn are investing in marketing drought-tolerant maize varieties and taking the products to scale.
A.M.: The DTMA and STMA projects were jointly implemented by CIMMYT and IITA in partnership with diverse national and private sector partners in major maize producing countries in eastern, southern and western Africa to develop and deploy multiple stress-tolerant and productive maize varieties to help farmers adapt to recurrent droughts and other stresses including climate change.
These projects catalyzed the release and commercialization of numerous stress-resilient new maize varieties in target countries across Africa. Increasing the resilience of farming systems means that smallholder farmers need guaranteed access to good quality stress resilient maize seeds. To this end, the two projects worked with public and private sector partners to produce large quantities of certified seeds with a continual supply of breeder seeds from CIMMYT and IITA. The availability of considerable amount of certified seeds of resilient maize varieties has enabled partners to reach farmers producing maize under stressful conditions, thus contributing to the mitigation of food shortages that affect poor people the most in both rural and urban areas.
C.M.: The drought-tolerant maize innovation stabilized maize production under drought stress conditions in sub-Saharan Africa countries. Recent study results showed that households that grew drought-tolerant maize varieties had at least half a ton more maize harvest than the households that did not grow the drought-tolerant maize varieties, thus curbing food insecurity while simultaneously increasing farmersâ economic benefits. Besides the benefit from drought-tolerant innovation, the new maize varieties developed through the partnership also stabilized farmersâ yields under major diseases, Striga infestation, and poor soil fertility prevalent in sub-Saharan Africa.
How is the project addressing emerging challenges in breeding for drought-tolerant maize and what opportunities are available to address these challenges in the future?Â

B.M.P.: A strong pipeline of elite, multiple-stress-tolerant maize varieties â combining other relevant adaptive and farmer-preferred traits â has been built in sub-Saharan Africa through a strong germplasm base, partnerships with national research partners and small- and medium-sized seed companies, an extensive phenotyping and multi-location testing network, and engagement with farming communities through regional on-farm trials for the identification of relevant farmer-preferred products.
CGIAR maize breeding in sub-Saharan Africa continues to evolve in order to more effectively and efficiently create value for the farmers we serve. We are now intensively working on several areas: (a) increasing genetic gains (both on-station and on-farm) through maize breeding in the stress-prone environments of sub-Saharan Africa by optimizing our breeding pipelines and effectively integrating novel tools, technologies and strategies (e.g., doubled haploids, genomics-assisted breeding, high-throughput and precise phenotyping, improved breeding data management system, etc.); (b) targeted replacement of old or obsolete maize varieties in sub-Saharan Africa with climate-adaptive and new varieties; (c) developing next-generation climate-adaptive maize varieties with traits such as native genetic resistance to fall armyworm, and introgressed nutritional quality traits (e.g., provitamin A, high Zinc) to make a positive impact on the nutritional well-being of consumers; and (d) further strengthening the breeding capacity of national partners and small and medium-sized seed companies in sub-Saharan Africa for a sustainable way forward.
A.M.:Â The DTMA and STMA projects established effective product pipelines integrating cutting-edge phenotyping and molecular tools to develop stress-resilient maize varieties that are also resistant or tolerant to MLN disease and fall armyworm. These new varieties are awaiting release and commercialization. Increased investment in strengthening public and private sector partnerships is needed to speed up the uptake and commercialization of new multiple stress-resilient maize varieties that can replace the old ones in farmersâ fields and help achieve higher yield gains.
Farmersâ access to new multiple-stress-tolerant maize varieties will have a significant impact on productivity at the farm level. This will largely be due to new varietiesâ improved response to fertilizer and favorable growing environments as well as their resilience to stressful production conditions. Studies show that the adoption of drought-tolerant maize varieties increased maize productivity, reduced exposure to farming risk among adopters and led to a decline in poverty among adopters. The availability of enough grain from highly productive and stress-resilient maize varieties can be the cheapest source of food and release land to expand the cultivation of other crops to facilitate increased access to diversified and healthy diets.
C.M.: Â The project is tackling emerging challenges posed by new diseases and pests by building upon the successful genetic base of drought-tolerant maize. This is being done by breeding new varieties that add tolerance to the emerging disease and pest challenges onto the existing drought-tolerant maize backgrounds. Successes have already been registered in breeding new varieties that have high levels of resistance to MLN disease and the fall armyworm pest.
Opportunities are also available to address new challenges including: pre-emptively breeding for threats to maize production challenges that exist in other regions of the world before these threats reach sub-Saharan Africa; enhancing the capacity of national partners to build strong breeding programs that can address new threats once they emerge in sub-Saharan Africa; and sharing knowledge and novel high-value breeding materials across different geographies to immediately address new threats once they emerge.
