In Zimbabwe, smallholder farmers like Ranganai Shonhiwa and Martha Chivengwa are facing the harsh realities of climate change, with erratic rainfall and prolonged droughts threatening their maize crops—their primary source of food and income. However, drought-tolerant maize varieties, developed through decades of research by CIMMYT and partners, are proving to be a game-changer. These resilient crops, combined with climate-smart farming practices such as reduced tillage and intercropping with legumes, are helping farmers maintain yields despite extreme weather conditions. With CIMMYT’s ongoing efforts in 19 districts across Zimbabwe, farmers are seeing improved harvests, increased incomes, and renewed hope for a more food-secure future.
Zimbabwean farmers are facing severe crop losses due to the combined impacts of climate change, drought, and fall armyworm infestations, threatening food security and livelihoods. CIMMYT’s expertise in climate-smart agriculture is crucial in tackling these challenges, as highlighted by Dr. Christian Thierfelder, who emphasizes sustainable pest management strategies such as intercropping, regenerative farming, and biological control methods. These approaches not only reduce reliance on pesticides but also enhance resilience against climate-driven pest outbreaks. With maize yields at risk, integrating CIMMYT’s research-driven solutions can help smallholder farmers adapt, ensuring more sustainable and productive farming systems in Zimbabwe and across sub-Saharan Africa.

In Zimbabwe, CGIAR, through CIMMYT, runs a maize breeding program to strengthen food security and livelihoods in a country where maize is a staple crop. The program spans diverse testing plots – managed exclusively by men, women, or both – providing crucial insights into real-world farm dynamics. A significant component of our work is the extensive on-farm trials conducted across various regions, helping us understand how men and women farmers interact with and benefit from new maize varieties. Here are two ways we ensure that women-managed plots reap the same benefits as those led by men in Zimbabwe.
Increasing Women’s Representation in Crop Breeding Trials
This dichotomy highlights the importance of on-farm trials in the crop development process, as they provide insights into the diverse needs and realities of different farmer groups.
Zimbabwe’s maize breeding program has expanded on-farm trials significantly over the past few years, by over five-fold. However, women-managed plots are often underrepresented in participatory approaches. Research from Kenya also showed that trial participants are often wealthier and more educated, benefiting from stronger access to information and agricultural networks.
Training to Ensure Inclusive Farmer Representation
CGIAR and CIMMYT often rely on partners with direct connections to farming communities to select host farmers for breeding trials. Recognizing the risk of bias and underrepresentation of women farmers in this process, we designed a training program for extension officers to ensure a more representative selection of women farmers from different socioeconomic backgrounds in the country.
Without intentional representation, trial results may skew toward wealthier, male-managed farms – limiting their relevance for the broader farming population. In addition, in Zimbabwe, women-managed households are not a homogeneous group. Our research identified two distinct categories, each with unique challenges and needs. One group was wealthier in terms of agricultural assets and livestock, with a greater area under maize production. The second group of women-managed households was more resource-poor, with smaller livestock herds and greater use of intercropping within maize fields.
Using data from a survey of over 2,000 farmers, we worked to validate farmer selection processes, ensuring that women farmers were accurately represented. Today, this training is conducted annually and has become a key component of our program’s approach.
For too long, on-farm trials did not adequately reflect the diversity of farming realities. Through this gender-sensitive approach, we are now able to fine-tune recruitment methodologies to account for socioeconomic disparities. By ensuring that all groups are included in trials, we can develop and promote maize varieties that truly serve the diverse realities of Zimbabwean farming households.

Incorporating Gender and Social Considerations into the Testing of Novel Genetic Technologies
In hybrid maize seed production, both male and female plants are planted side by side to facilitate controlled pollination. A critical step in this process is detasseling – the removal of male flowers (tassels) from the female plants to prevent self-pollination. If detasseling is not done correctly, the resulting seeds will not express hybrid vigor, ultimately affecting yield and performance.
This process presents two major challenges. Incomplete detasseling can result in hybrid purity issues that can lead production fields to either being rejected or farmers unknowingly paying for lower-quality seed that impacts productivity. Accidental leaf loss during the detasseling process also reduces female seed yields by approximately 14%.
To address these challenges, a Gates Foundation-funded project we implemented has explored ways to simplify the process of hybrid maize seed production by removing the need to detassel through a novel genetic technology. This technology also had a clear benefit for women farmers.
Why This Matters and How to Scale the Innovation
Although seed production involves multiple steps, this innovation has direct benefits, especially in resource-limited settings. Since only 50% of plants produce pollen, this approach optimizes yield—particularly under low-nitrogen conditions, where many smallholder farmers struggle. The technology is adaptable across different maize varieties, making it a scalable solution.
To validate this approach, we conducted station trials, followed by on-farm testing. These trials are helping us understand how both men and women farmers adopt and benefit from these varieties, particularly in drought-prone areas, where women are more likely to recycle seeds.
With the knowledge that in drought-prone years women were more likely to recycle hybrid seed, we refined our testing strategy to evaluate potential yield benefits if recycled. We found the technology provided a small, yet significant yield benefit should a farmer choose to recycle hybrid maize seed in an anticipated drought season.
Our approach provides insights into how gender and social inclusion considerations can be incorporated into breeding testing strategies. By evaluating variety performance across real-world farm conditions and gathering insights to refine and optimize future breeding efforts, new varieties will meet the needs of men and women farmers in Zimbabwe.
Conclusion
When promoting the adoption of new maize varieties and technologies, gender is one factor among many that shape adoption. Early- and late-stage on-farm trials are essential in bridging the gap between scientific innovation and real-world impact, ensuring that the varieties we develop are not only high-performing in research settings but also practical, accessible, and beneficial for all farmers.
To achieve this, a transdisciplinary approach is key. Integrating social scientists into breeding and development strategies provides deeper insights into how different farming groups interact with new technologies. By refining our selection process, testing, and deployment, we can ensure that both women- and men-managed farms benefit equitably, ultimately driving food security and better livelihoods.

Agriculture lies at the core of rural livelihoods, yet longstanding social inequities havestifled the potential of marginalized groups– particularly women and youth– to fully benefit. The CGIAR Agroecology Initiative (AE-I) recognizes gender and social inclusion as critical pillars in achieving sustainable agricultural transformation. By embedding these aspects within its framework, AE-I ensures that marginalized groups—especially women and youth—play a meaningful role in agroecology transitions.
Current realities on women and youth in agriculture
Women and youth are central to Zimbabwe’s agricultural economy, yet they remain underrepresented or excluded in decision-making processes and face barriers to accessing critical resources. Globally, women make up about 48% of the agricultural labor force in Sub-Saharan Africa (World Bank, 2024), yet they consistently face challenges in accessing land, credit, and markets. In Zimbabwe, these disparities are even more pronounced. In Mbire and Murehwa districts, rural economic activities, including agriculture, rely heavily on women and youth. Women make up approximately 70% of the agricultural labor force (UNDP, 2024) in these regions, but they often lack control over resources needed to enhance productivity and economic stability such as land, credit, and markets.
Agroecology Living Landscapes and Gender and Social Inclusion Matter
Embedding gender and social inclusion (GESI) into agroecology is not just a moral imperative but a foundational requirement for achieving lasting and transformative impact. Traditional top-down development approaches have often neglected marginalized groups’ unique needs and contributions, resulting in unsustainable outcomes. In contrast, the AE-I prioritizes inclusive and participatory processes, exemplified by its Agroecology Living Landscapes (ALLs), which serve as collaborative spaces where community members actively co-create locally relevant solutions.
Central to the CGIAR Agroecology Initiative (AE-I) is a commitment to “do no harm—say no harm,” ensuring that the inclusion of women, youth, and other marginalized groups is safe, meaningful, and impactful. Including marginalized groups can disrupt existing power structures and opportunity hierarchies, so it must be done with contextual sensitivity. Young and old women are provided equal opportunities to participate in and contribute to the co-creation of innovations. However, systemic barriers-such as limited agency or entrenched gender norms-continue to hinder meaningful engagement. To address these challenges, AE-I collaborates with key stakeholders, such as the Ministry of Women Affairs, Community, Small and Medium Enterprises Development (MWACSMED), to advocate for gender mainstreaming. Concrete actions have included training programs, documentation of gender norms and their impacts, elevating women and youth role models, and ensuring equal participation in ALL activities. MWACSMED has evolved into a proactive stakeholder in this process. Initially a passive participant in ALL discussions, the ministry now plays a leadership role in addressing gender and social inclusion issues within the landscapes. This deliberate attention to GESI within ALLs has illuminated systemic barriers such as unequal access to resources, rigid cultural norms, and the exclusion of certain social groups.

Agroecology recognizes that inclusion is not merely about representation but about fostering environments where meaningful transformation can happen. For instance, cultural norms often limit the participation of women and youth in mixed-group activities. To address this, the AE-I initiated monthly “dialogues with elders,” engaging traditional authorities and community leaders to reconcile cultural traditions with transformative gender and social inclusion goals. These dialogues have yielded positive shifts in such perspectives. As one elder participant noted, “We value inputs from women and acknowledge their critical role in our community.”
The transformative impacts of AE-I’s inclusive approach are increasingly visible. Across Murehwa and Mbire districts, Agroecology Living Landscapes (ALLs) are reshaping community dynamics by empowering previously marginalized groups, such as elderly women, to contribute to agricultural innovation. Within some of the activities of the Initiative, women and youth engagement is quite impressive, with over 60% of participants in seed fairs and field days. These figures highlight the significant potential for expanding women’s and youth’s opportunities to advance agroecological goals through gender- and youth-focused interventions. It also demonstrates their eagerness to engage in knowledge-sharing opportunities. Such initiatives improve livelihoods and build women’s and youths’ agency as active contributors to agricultural innovations.
Inclusivity within ALLs is further is reinforced by low barriers to entry, emphasizing a willingness to learn and transform their crop and livestock production rather than asset ownership. This approach has expanded participation among resource-poor farmers, breaking down traditional exclusionary practices brought by other Donor programs.
As one farmer remarked, “In the past, only those with cattle or fenced homesteads could join such programs on transformative change. Now, even those of us without such assets can participate.”
Such practices have strengthened the confidence of marginalized farmers, enabling them to navigate complex production dynamics collectively.
Building Economic Independence and Transforming Food Systems
The AE-I’s focus on inclusive value chains has begun to yield tangible economic benefits. In Mbire and Murehwa, women are transitioning from subsistence farming to economic independence by engaging in agroecological business models. For example, Sasso poultry farming has become a viable income-generating activity, allowing women to reinvest in their farm-level activities. Youth are also leveraging their involvement in agriculture to build assets, diversify income and nutritional sources, and secure a more stable future.
A critical challenge remains exploitative market dynamics that limit farmers profitability. Farmers have raised concerns about the informal urban markets, where asymmetric power dynamics and a lack of competitive pricing mechanisms enable buyers to dictate unfavorable prices. Middlemen in the poultry markets suppress prices by 40%, while unstructured sorghum buyers pay 20–30% below market rates, eroding farmers’ profitability.
Addressing these bottlenecks through cooperative-led marketing, digital trading platforms (e.g., Hamara App), and guaranteed off-take agreements ensures equitable economic participation and a resilient food system.
Drudgery and Women in Agri-Food Systems
The transition to agroecology offers both opportunities and challenges, particularly for women, who bear the brunt of agricultural labor. In many rural communities, women are responsible for labor-intensive activities, including land preparation, weeding, and post-harvest handling.
While agroecological practices promote sustainability and resilience, some approaches—such as conservation agriculture—can initially increase women’s workload, exacerbating drudgery and limiting their time for other economic or social activities.
To ensure that agroecology transitions are both equitable and scalable, it is essential to integrate appropriate-scale mechanization that reduces labor burdens while maintaining ecological integrity. By embedding gender-responsive technologies into agroecological systems, AE-I can foster inclusive, productive and sustainable farming solutions.

To address this, the Initiative has facilitated the adoption of labor-saving technologies, improving access to mechanized solutions that ease women’s workload. In Mbire and Murehwa districts, 43 out of 95 women farmers now have access to basin diggers, significantly reducing the effort required to establish planting basins in conservation agriculture. Additionally, four multigrain threshers have been introduced in each district, enabling women to process small grain cereals more efficiently, cutting down the time spent on post-harvest handling.
These innovations not only alleviate physical strain but also increase productivity, allowing women to participate in value-added activities and play a greater role in decision-making processes within the food system.
By prioritizing appropriate-scale mechanization, the AE-I ensures that agroecology transitions foster inclusivity, sustainability, and economic empowerment for women farmers.
Wrap up
The CGIAR Agroecology Initiative’s work in Mbire and Murehwa provides a step forward for centering gender and social inclusion into agricultural development. Through participatory methods, inclusive partnerships, and a focus on actor agency and opportunity for behavior change, the Initiative has redefined what it means to build sustainable and equitable food systems. For donors, partners, and other stakeholders, the AE-I offers a compelling case for investing in inclusive approaches that transform agriculture and uplift entire communities. As agroecology continues to evolve, centering gender and social inclusion will remain vital for achieving sustainable, impactful outcomes.
CIMMYT has strengthened agricultural research and breeding programs in Zimbabwe by donating machinery to Gwebi College of Agriculture to modernize breeding efforts and enhance genetic gains. This support equips breeding stations with advanced tools, reduces field labor, and expands research opportunities, including for women in technical roles. By fostering research partnerships and developing high-yield, climate-resilient maize varieties, CIMMYT is driving innovation to combat pests, diseases, and climate challenges, ultimately improving smallholder farmers’ productivity and supporting Zimbabwe’s goal of increasing maize yields.
A handful of azolla (Photo: Telma Sibanda, CIMMYT)
Often referred to as “green gold,” Azolla is a small, free-floating and fast-growing aquatic fern with immense potential in driving towards agriculture sustainability. Thriving in waterlogged environments, this hardy plant forms a symbiotic relationship with nitrogen-fixing cyanobacteria, making it a natural fertilizer for crops like rice. Rich in protein, Azolla is also an affordable, eco-friendly feed for livestock and fish, reducing reliance on commercial alternatives. Its rapid growth and carbon sequestration capabilities contribute to climate resilience and resource efficiency. The water in the pond is enriched with nitrogen and can be used to irrigate plants/crops, increasing its value to farmers. Farmers in low-income regions are embracing Azolla as a game-changer, unlocking opportunities to boost productivity, improve soil health, and transition toward more sustainable farming practices.
Recognizing Azolla’s potential, the CGIAR-funded Transformational Agroecology across Food, Land, and Water Systems Initiative, also known as the Agroecology Initiative (AEI) in Zimbabwe, is integrating it into agroecological approaches in Murehwa. This initiative, which operates through five work packages (WPs), is reimagining farming systems by combining innovative business models (WP3) with agroecological technologies (WP1).

In one of the districts in Murehwa, AEI Zimbabwe selected poultry business model working in collaboration with Hamara Chicks, focusing on resilient and dual-purpose Sasso chickens. Known for their resistance and ability to free-range, these chickens provide both meat and eggs, offering farmers diversified income streams. Hamara Chicks implemented a two-stage model: first the brooding stage, where farmers raise chicks up to four weeks old and then sell them to other farmers who raise them from juveniles to maturity. While promising, the first cycle faced challenges, including a lack of affordable, nutritious feed, and difficulties in securing a market post-brooding and after maturity. To address these issues, WP1 and WP3 identified Azolla as a potential supplemental or alternative feed to support the poultry business model.
The dilemma of Azolla: Two sides of the coin
Azolla farming offers a compelling mix of benefits for sustainable agriculture. Environmentally friendly and resource-efficient, Azolla farming requires minimal land, water, and inputs, making it particularly suitable for small-scale farmers seeking cost-effective solutions. Its rapid growth is one of its standout attributes; under optimal conditions, Azolla can double its biomass in just 3-5 days. This rapid growth allows farmers to produce significant quantities of forage with limited investment, significantly reducing feed costs and increasing overall profitability. Its ability to be harvested daily ensures a consistent and reliable feed supply.
Nutritionally, Azolla is a powerhouse. With a protein content of 25-30% (dry weight), it is packed with essential amino acids, vitamins such as A, B12, and beta-carotene, and essential minerals. When incorporated into livestock and poultry diets, Azolla contributes to improved health, faster growth rates, and better production results. For smallholder poultry farmers, these benefits translate into tangible gains in meat and egg production, providing a pathway to higher incomes. Moreover, Azolla’s agricultural utility extends beyond animal feed. Its nitrogen-fixing capability enriches soil fertility, reducing reliance on synthetic fertilizers and supporting sustainable crop production systems.
However, as promising as Azolla is, its cultivation is not without challenges. Water availability is a critical requirement, posing a potential barrier in regions with limited water resources. In Murehwa, Zimbabwe, where the CGIAR-funded Transformational Agroecology Initiative is promoting Azolla, horticulture farmers already have access to reliable water sources, alleviating this concern.
Another challenge is the maintenance of Azolla ponds. To thrive, Azolla requires well-managed conditions, including optimal pH levels and nutrient balance. Poorly maintained ponds can compromise growth and productivity. Recognizing this, farmers participating in the initiative have received extensive hands-on training to effectively manage and sustain these conditions effectively, ensuring that Azolla remains a viable and productive resource.
Empowering farmers through training and capacity building
The initiative partnered with KDV Consultancy to train 70 farmers, including 40 women in Murehwa, equipping them with essential skills for Azolla cultivation. The training sessions focused on pond construction, maintenance, and integration of Azolla into poultry feeding systems. This hands-on approach ensures that farmers can sustainably enhance their poultry value chains.

By co-designing solutions with farmers, the initiative prioritizes their needs and challenges, and promotes practical, farmer-driven outcomes. Empowering farmers with the knowledge and tools to implement sustainable practices not only strengthens their resilience but also enhances the long-term sustainability of poultry production in Murehwa. This collaborative effort is laying the groundwork for a more robust and adaptive agricultural future.
The integration of Azolla farming represents a promising step towards achieving a more sustainable and resilient agricultural system in Murehwa. By addressing the feed challenges faced by poultry farmers, Azolla not only enhances poultry production but also contributes to the broader goals of food security and economic stability in the region. As the Transformational Agroecology across Food, Land, and Water Systems project progresses, the positive impacts of innovative practices like Azolla farming continue to support the well-being and livelihoods of farmers in Murehwa.
As part of the CGIAR Initiative on Agroecology, the Feed the Future Zimbabwe Mechanization and Extension activity participated in the 2024 Agroecology Fairs held in Murewa and Mbire districts on September 25 and October 17, 2024, respectively. The events provided valuable platforms to collaborate with the initiative and showcase different scaling pathways for mechanization within the context of sustainable, efficient farming.

At the Mechanization and Extension activity’s exhibition stand, visitors explored an array of machinery specifically tailored to small-scale farming needs. Among the featured equipment were basin diggers, two-wheel tractors, multi-crop threshers, chopper grinders, trailers, and peanut butter processing machines, including a groundnut sheller, peanut roaster, and peanut butter-making machine. Each piece of equipment aligns with existing activities within the initiative to demonstrate practical solutions for improving labor efficiency and enhancing crop productivity which might be needed during agroecology transitions.
The basin digger drew significant attention, especially from farmers encountering it for the first time or wanting to know more about how they could become service providers. Designed for creating basins such as those established under the Pfumvudza/Intwasa conservation agriculture program, the basin digger can significantly reduce labor and time in land preparation, especially for those with limited access to manual labor.
The service provision model: a pathway to accessible mechanization
Participants interested in the service provision model received first-hand information on the benefits of the program and how they could sign up. The service provision model is a key part of the Feed the Future Zimbabwe Mechanization and Extension activity, designed to facilitate year-round access to mechanization services in farming communities.
Through this model, trained service providers are established locally, offering a range of fee-based services, including land preparation, crop management, post-harvest processing, value addition, and transportation. This model makes essential machinery accessible to farmers without requiring them to purchase it outright. To support the establishment of service providers, three financing options are offered:
Loan facility: Prospective service providers apply for a loan from BancABC, with a 30% initial deposit of the total machinery cost. Upon approval, the balance is paid directly to the machinery supplier, who then delivers the equipment.
Hire purchase agreement: Service providers may opt for a hire purchase arrangement with the manufacturer, where machinery is provided after an agreed deposit, with the remaining balance paid over three to four months.
Outright cash purchase: Community members with funds can purchase machinery.
Strong community interest and prospects for growth
The Mechanization and Extension activity stand generated substantial interest among farmers in both districts. In Murewa, 95 participants engaged with the display, with eight potential service providers expressing interest in acquiring the peanut butter-making machine, manual groundnut sheller, and peanut roaster. Groundnut production is high in Murewa, so farmers were especially intrigued by the value addition machinery, which opens new opportunities for processing and marketing.
“As groundnut farmers, these machines will give us a business opportunity to sell peanut butter in large quantities,” said attendee Colleta Nzara of Murewa district.
“We used to lose so much money by just selling unshelled groundnuts because very few could manually process into peanut butter, but with these machines, the whole process is so much easier,” said Florence Mutize of Murewa district.
In Mbire, where 57 participants visited the stand, the basin digger was a major attraction.
“This is the first time I am seeing this machine that can ease our labor burdens when making our Pfumvudza plots,” said Jennifer Nyatande from Mbire district. “I’m eager to invest in one to both reduce costs on my farm and offer services to others.“

The 2024 Agroecology Fairs provided an opportunity to demonstrate how mechanization can be both accessible and transformative for smallholder farmers. With growing interest from local communities, the Mechanization and Extension activity continues to work toward sustainable agricultural development across Zimbabwe’s rural districts.
CIMMYT, through the CGIAR-supported Ukama Ustawi initiative, is supporting women farmers in Zimbabwe to lead the fight against climate change. By adopting climate-smart practices like zero tillage and growing drought-resistant crops such as orange maize, cowpeas, and lab-lab, farmers like Susan Chinyengetere are ensuring food security, generating income, and inspiring others. These techniques not only strengthen resilience against erratic weather but also enable women to balance traditional roles while driving sustainable agriculture. With access to affordable seeds, mechanization, and strong farmer networks, CIMMYT is fostering lasting solutions to climate adaptation across Zimbabwe and beyond.
Climate Change and Child Malnutrition in Zimbabwe: Evidence to Action will generate evidence to understand the effects of climate change on child malnutrition in rural Zimbabwe. The overarching hypothesis is that climate change and related weather events indirectly increase child malnutrition by increasing food insecurity and decreasing dietary diversity.
This project will use a multisectoral approach to evidence generation and co-creation of community and policy action that incorporates village, district, provincial and national participation. The project aims to generate evidence linking climate change to malnutrition and co-develop mitigation strategies with communities that directly address the link between climate change and malnutrition.
The project has four activities:
Examine the relationship between climate change in rural Zimbabwe and patterns of malnutrition utilizing environmental data (rainfall, temperature) and national Zimbabwe survey data (livelihoods, climate change mitigation strategies, dietary diversity and child malnutrition).
Explore community understanding of the relationships between climate change and malnutrition with a mixed methods approach in two districts (survey and community-led workshops).
Co-develop and refine climate-smart strategies that address the effects of climate change on malnutrition with agricultural and health cadres.
Develop a communication plan with policymakers to disseminate findings about the relationship between climate change to child malnutrition.
Objectives:
Use environmental data and national-level survey data on climate change and shocks related to climate change and examine associations with nutritional outcomes including food security, dietary diversity and child malnutrition.
Conduct household surveys to understand how agricultural and child feeding practices change under climate variability.
Conduct community workshops using community walks and River of Life Methodology to understand community perspectives on the relationship between climate change and child malnutrition.
Co-develop and refine climate-smart strategies that communities can implement to directly address the relationship between climate change and malnutrition.
Pilot implementation of strategies in two sites utilizing community health and agricultural extension workers.
Share results with policy makers to contextualize malnutrition in the context of climate change policy.
CIMMYT has been at the forefront of promoting conservation agriculture (CA) in Southern Africa, leveraging over 20 years of research to enhance food security and resilience to climate change. By introducing innovative mechanized tools like basin diggers, CIMMYT has significantly reduced labor demands, making CA more accessible for smallholder farmers. The organization collaborates with partners, including FAO, to integrate CA into national policies, such as Zambia’s mechanization strategy, while also providing education and technical support to farmers. CIMMYT’s efforts empower farmers to increase yields, improve soil health, and generate additional income, exemplifying its commitment to sustainable agriculture in the region.

In the heart of Mbire’s Ward 2 in Zimbabwe, Tichaona Makuwerere has earned the trust of his community, not just as a farmer but also as a resourceful problem-solver. His journey began with “piece jobs” — manual labor that barely made ends meet. From providing firewood and bricks to renting an ox-drawn cart, Tichaona’s days were filled with tough and gritty work. Occasionally, he crossed into Zambia to collect baobab fruit for sale, returning with livestockpesticides, which he traded locally.
However, stability remained elusive. Jobs were scarce, and community hiring often favored personal connections. Undeterred, Tichaona turned to self-employment in 2007, offering ox-drawn ripping services to farmers. His commitment didn’t go unnoticed. When the CGIAR Agroecology Initiative (AEI) came to Mbire, the community recognized Tichaona’s entrepreneurial spirit and nominated him as a service provider.
AE-I brings together farmers and stakeholders to address local challenges and develop practical solutions in Mbire and Murewa. Through Agroecological Living Landscapes (ALLs)—collaborative spaces for innovation—various stakeholders work to identify, co-design, test, and adopt agroecological practices. One challenge identified was that agroecology can be labor-intensive, highlighting the need to reduce labor demands by integrating mechanization for manual activities such as crop planting, manure transportation, and threshing. Partnering with private sector organizations like Kurima Machinery, AE-I provides farmers in Mbire and Murewa with the tools and training necessary to make mechanized services more accessible.
Equipped for success through training and support
Tichaona’s journey with AE-I began with intensive training at Gwebi College of Agriculture in Zimbabwe, where he learned the intricacies of machine operation, repair, and business management. The hands-on experience gave him the confidence he needed. “It was a turning point,” said Tichaona. “The training gave me skills that are hard to come by here. I learned how to run and sustain an agricultural service business.”
In addition, Kurima Machinery provided practical guidance and support when delivering his new equipment kit, which included a two-wheel tractor, trailer, grass cutter, chopper grinder, ripper, thresher, and basin digger. Although Tichaona had no prior experience with engines, his determination, along with Kurima’s ongoing virtual support, helped him develop the skills needed to operate and maintain the equipment.
Scaling up from oxen to efficient mechanization
The kit has dramatically transformed Tichaona’s way of working. Where he once struggled with oxen, the two-wheel tractor can now complete a three-hour task in just 30 minutes. This leap in efficiency has enabled him to expand his services beyond ripping and transportation. Tichaona now offers grass cutting, baling, grinding, threshing, and basin digging services.
Mechanization has not only streamlined his business but also significantly increased his clientele. Previously, he served around 50 clients per year; now, with the tractor, he supports over 200 annual clients, many of whom are repeat customers. In a region where animal feed is scarce during the dry season, Tichaona’s baling services have become especially valuable. Over the past year, he has produced more than 3,000 bales, even attracting safari operators who use the bales as bait for animals.
“Hatisi kumira kutsvaga mabasa” (We keep going forward and look for new jobs), Tichaona reflected with pride. In his drive to grow, he has further diversified his services to include grinding forest products such as Faidherbia albida, acacia, and Piliostigma thonningii pods, producing affordable livestock feed for farmers. He acquired these skills during livestock feed production training at the ALLs.
Mechanization has not only improved productivity but also mitigated environmental risks. Grass cutting and baling have curbed the practice of uncontrolled burning, which previously caused frequent veld fires in Mbire and Murehwa. In recognition of the project’s success in promoting sustainable land use, the Environmental Management Authority (EMA) has invested in additional service kits for other wards.

Strengthening Resilience Amid Climate Uncertainty
Tichaona’s services have become indispensable in a community grappling with erratic weather patterns and prolonged droughts. By baling grass, sorghum stalks, and crop residues, he enables farmers to store feed for their livestock, mitigating risks during drought seasons. The benefits extend beyond livestock care—his machinery has helped farmers expand cultivable areas despite a shrinking planting season.
Moreover, Tichaona has stepped up as a water carrier during the dry months. With wells drying up, villagers often dig makeshift wells in distant riverbeds. Using his tractor, Tichaona fetches water from the borehole for the community. His efforts free up time for farmers to focus on land preparation and other critical tasks, boosting their productivity.
Building a Lasting Legacy at the Community Level
Tichaona’s success has translated into significant improvements for his family. His increased income has allowed him to build a new home and purchase land in Guruve town. He has also invested in goats for his children as a form of social security. “Kudya kaviri kwaitonetsa, ikozvino takutodya uye atichatenderi kuti muenzi asvika abve pamba asina kudya (We could barely afford two meals a day, but now we eat more than four meals. We ensure that no visitor leaves without eating),” he shared.
His generosity extends beyond his family. Tichaona provides free transportation for vulnerable residents, including the elderly, and offers free grinding services to low-income families. These acts of kindness have solidified his reputation as a respected and valued member of the community.
A Model of Adaptability and Determination
Tichaona’s journey has not been without challenges. Mechanical issues, such as trailer body wear, brake replacements, and two-wheel tractor bearing failures, have tested his resourcefulness. He stocks essential spare parts, conducts regular maintenance, and leverages Kurima Machinery’s support network for troubleshooting and repairs. Collaborating with other AE-I operators, he shares tips and techniques for maintaining machinery, ensuring consistent and reliable services.
As his confidence and skills grow, Tichaona is planning to expand his offerings. He envisions adding oil pressing for sunflower and groundnut as well as peanut butter production. Already, he has invested in a grinding mill operated by his wife, allowing him to focus on field services. His ambitions extend to poultry farming, where he plans to use his chopper grinder to produce feed, incorporating local products into his supply chain.
“Ndine hurongwa hukuru” (I have bigger plans ahead), Tichaona said. He dreams of drilling a borehole to support horticultureproduction, a venture that would benefit not only his family but also nearby farmers by providing easier access to water. His ultimate goal is to establish a comprehensive agricultural service hub, offering everything from land preparation to livestock feed production, to strengthen the community’s resilience.
A Model for Agroecological Transformation
Tichaona’s story exemplifies the far-reaching impact of empowering local service providers in rural agriculture. Through the CGIAR Agroecology Initiative, he transformed from being a community handyman to a pioneering agricultural entrepreneur in Mbire. His contributions not only enhanced agricultural efficiency and overall life for himself and his community, but also offered a blueprint for sustainable development in agriculture. His story reminds us that when local expertise is supported and equipped, it can transform communities into models of resilience and sustainable growth.
Gogo Consilia Nyamunda in her pigeon pea field (CIMMYT)
When she first ventured into growing pigeon peas as a baby trial host farmer, Gogo Consilia Nyamunda doubted that intercropping them with maize would bring any benefits, especially given the weather had not been lenient over the past few years in Buhera district, in eastern Zimbabwe. “This year has been the hardest. I’ve never experienced such drought and heat stress, but it’s not just me—it’s affecting the entire country,” says Gogo Consilia. Yet, her production turned out to be better than that of farmers growing only maize, a popular crop in Southern Africa. Encouraged by the results, she expanded her efforts, dedicating half a hectare to pigeon peas. “From just 0.2 hectares of pigeon peas, I still managed to harvest 10 kilograms in these extremely dry conditions. It’s not just for feeding my chickens—other farmers are now interested in the seeds as well,” she explains.
In the face of a changing climate, building the resilience of local farmers is crucial to safeguarding both their meal baskets and livestock feed. In this context, LIPS Zimbabwe has emerged as a strategic initiative, deeply rooted in farmer-driven trials to scale fodder production while maximizing the potential of mechanization for smallholder farmers in Buhera. By integrating improved agronomic practices with scalable fodder production, LIPS Zimbabwe is helping farmers withstand the challenges posed by climate change.

In the same district, Shirley Makoni also began as a baby trial farmer, intercropping maize with jack bean, a leguminous crop resilient to drought. Her case highlights the importance of diversifying crops and adapting to the realities of climate change: despite initial skepticism, Shirley found that jack beans not only survived the drought but also provided valuable feed for her cows. “I didn’t think anything would come out of it, but the cows love the leaves and seeds. They’ve gained weight, and the crop has been easy to manage,” she shares. While her maize and other crops failed due to the severe weather, jack bean proved to be a reliable source of feed, allowing her to bale the leaves and even share the harvest with others.

One of the key strategies employed by LIPS Zimbabwe is the promotion of resilient fodder crops that can thrive under harsh climatic, semi-arid conditions where potential evapotranspiration far exceeds seasonal rainfall, which is often below 600 mm. This approach not only ensures a reliable source of feed for livestock but also contributes to the overall resilience of farming systems. The success story of farmers like Gogo Consilia Nyamunda highlights the transformative impact of these efforts.
“The idea of testing new innovations has paid off. Despite the poor sandy soils in Buhera, these fodder crops (jack bean and pigeon pea) have done well!” says Isaiah Nyagumbo, a Systems Agronomist leading the CIMMYT component of the LIPS-Zim project. “This means we now have a more diverse range of leguminous fodder crop species that can be grown in these semi-arid conditions, apart from the more common ones such as mucuna, lablab, and cowpeas.”
Some preliminary laboratory results also suggest that jack bean contains much higher crude protein than popular fodder legumes like mucuna. Jack bean could thus offer a new resilient feed option for farmers in these drought-prone regions and can be grown as an intercrop or in rotation with cereals.
Transforming fodder production through mechanization
Tying the LIPS Zimbabwe project together is the introduction of the mechanization component, from planting to processing the fodder crops, which is crucial for increasing the scale of fodder production in Zimbabwe’s semi-arid regions. By processing forage legumes such as jack bean, lablab, pigeon pea, mucuna, and cowpea, farmers can ensure a steady supply of nutritious feed for their livestock, even in the face of unpredictable weather patterns.
Local farmers in Buhera have been equipped with machinery such as a chopper grinder, hay balers, planters, and tractors, and trained to use and maintain the equipment. “Among the machinery at hand, the hay baler has been a great win for me, especially for the cows,” says Gandani Nhachi. “Last season, I made 27 bales of fodder, which has been vital for my herd. I’ve also grown my goat herd from 16 last year to 35 this year,” he proudly shares.
Building resilience for the future
As climate change continues to challenge farmers, initiatives like LIPS Zimbabwe are essential for building resilience. By combining traditional knowledge with modern practices, scaling fodder production, and embracing mechanization, farmers in Buhera are better equipped to protect their livelihoods and ensure food security. As Gandani puts it, “Climate change is inevitable, but with the right practices, we can still thrive. When I give my goats food, they multiply. Even if one side fails, all hope is not lost.”
Soils are the bedrock for plant health and sustenance, but how do we protect and enhance them to maximize their nutritional potential? Years of conventional farming practices have left many soils depleted, raising urgent concerns about how to rejuvenate them. The recent El Niño event during the 2023/24 farming season in southern Africa, bringing extreme weather conditions—ranging from prolonged droughts to intense floods—has exposed the vulnerability of these soils. Poorly managed soils, already strained by years of excessive tillage and lack of cover, struggle to retain moisture under such stress, leading to crop failures even after rainfall.
However, conservation agriculture (CA) offers a vital solution. By improving soil structure and moisture retention, CA practices provide a lifeline for crops in challenging conditions. Recognizing this, CIMMYT scientists are actively promoting CA among smallholder farmers across sub-Saharan Africa, highlighting its critical role in sustaining soil health and resilience in the face of climate challenges.
Described as lumps of soil particles that bind together strongly, soil aggregates play a vital role in maintaining soil health, supporting plant growth, and sustaining agricultural productivity. Formed by the combined effects of biological, chemical, and physical processes, the structure and stability of soil aggregates are crucial for several soil functions—primarily water infiltration, root growth, and resistance to erosion. Soil aggregates consist of various soil particles, including sand, silt, clay, and organic matter. There are different types of soil aggregates, including macroaggregates (>0.25 mm) and microaggregates (<0.25 mm), with macroaggregates typically more stable and beneficial for soil structure and functions.
Demonstrating the value of soil aggregate stability

Imagine three soil aggregate samples taken from the same field but under different management regimes—from virgin soil that has not been previously cropped, to land under conservation agriculture practices for the last 5 to 8 years, and soil conventionally ploughed annually before crop planting for many years. When these soil aggregates are gently immersed in clear water, stark differences can be noted. The aggregates from conventionally tilled soil, weakened by years of intensive cultivation, quickly disintegrate, turning the water murky and brown.
In contrast, the aggregates from virgin soil remain intact, preserving the water’s clarity even after several hours. The CA soil aggregates exhibit much better stability than those from the conventionally tilled soil but fail to remain as intact as those from the natural virgin soil. A simple lesson is drawn from this demonstration! Restoring degraded soils is a serious challenge. Even after 5 years of CA practices, soil organic carbon levels may only show modest improvement, and the aggregates, while more stable, still don’t match the condition of aggregates from virgin soil.
Soil recovery from a degraded state is a slow process that is not “a walk in the park.” Transitioning from conventional tillage to CA is challenging and slow, requiring years to rebuild organic matter and improve aggregate stability. Patience and careful soil management are vital, as degradation can occur rapidly, but recovery is a lengthy process. However, incorporating organic soil amendments like manure and compost, along with diversifying crops by introducing legumes such as cowpea, groundnut, soybean, mucuna, and pigeon pea, can accelerate this recovery. While degradation occurs rapidly, soil restoration demands a long-term commitment, but the rewards are worth the effort.
Exploring conservation agriculture as a source to improve soil health
Conservation agriculture is built on three key principles: reduced soil disturbance, permanent soil cover, and diverse crop rotation. Minimizing soil disturbance helps preserve soil structure, while permanent soil cover shields the soil against splash erosion and boosts microbial activity. Crop rotation enhances soil fertility, maintains aggregate structure, and disrupts pest and disease cycles. These principles are essential for soil recovery and the retention of organic matter.
Among these, permanent soil cover is often the most challenging for farmers to implement, yet it is critical for effective soil management. Demonstrating its importance, a simple test with water applied to soil samples with varying levels of cover illustrates splash erosion effects.
“Such a simple test mimics real-life conditions farmers face during rains. Soils without cover suffer significant erosion, while those with minimal or substantial cover show reduced erosion and improved water retention. This emphasizes the importance of maintaining permanent soil cover to foster microbial activity and enhance soil health,” highlighted Isaiah Nyagumbo, cropping systems agronomist.
In a nutshell, soil aggregate management is fundamental to climate resilience and agricultural sustainability. Through the adoption of conservation agriculture practices, smallholder farmers can significantly improve soil health, enhance water and nutrient retention, and increase crop resilience to climate stress. The journey from degraded to healthy soil is long and challenging, but with careful management and patience, the benefits are profound and lasting. By understanding and implementing these principles, farmers can build a more sustainable and resilient food system.

Maize productivity in eastern and southern Africa faces numerous challenges, including biotic and abiotic stresses, as well as socio-economic factors. To tackle these constraints, CIMMYT, in collaboration with partners, has been developing elite multiple stress-tolerant maize hybrids for different market segments. The hybrids are rigorously evaluated in research stations under managed stresses, especially those faced by farmers, including drought, heat, and low nitrogen. The process is complemented with evaluations conducted in actual farmer conditions through a participatory approach, which enables researchers to identify traits preferred by farmers.
Over the years, and through consistent engagement with farming communities, CIMMYT and partners have established a large on-farm testing network to allow farmers to test the best-performing hybrids within their own fields and management. This ensures that new varieties selected for commercialization suit the needs, constraints, and priorities of smallholder farmers.
Centrality of ROFT in the variety development process
Regional on-farm trials (ROFTs) are a crucial step towards maximizing the impact of breeding investments. ROFTs help scientists understand the performance of pipeline hybrids under diverse management conditions. The data and insights gathered from these trials, led by district leads, are instrumental in identifying the best varieties to release. In Zimbabwe, the extensive on-farm testing is conducted with support from Zimbabwe’s government extension arm, the Department of Agricultural, Technical, and Extension Services (Agritex), and selected seed companies.
To help track the progress or challenges in varietal performance evaluation at the farm level, CIMMYT has been convening feedback sessions with district agriculture extension officers (DAEOs) across 19 districts. These sessions have been instrumental in strengthening the collaboration with Agritex, standardizing data collection, and improving data quality and returns from the established on-farm testing network.

The ROFT trials have been ongoing in Zimbabwe for over a decade across 19 districts, located in natural regions I, II, and III. These trials have been implemented by more than 137 AEOs and have involved over 1,000 farmers. The network deliberately included a diverse range of farmers, with around 40% being female plot managers, to encompass a wide range of smallholder farming practices.
Participatory engagement is key
Every year, CIMMYT produces improved varieties that are then taken up by partners, including National Agricultural Research System (NARS) partners and seed companies. The on-farm trials aim to generate agronomic performance data in comparison to the widely grown commercial varieties and farmers’ own varieties. This data is used for a rigorous advancement process, where varieties that pass the test are then furthered for licensing and possible commercialization by CIMMYT’s partners.
Farmer involvement at the final stage of the variety selection process is key to the success of these trials. Farmers evaluate the varieties based on their specific needs, on their farms. This step is crucial as it empowers farmers to have a say in the variety development process. CIMMYT actively uses this participatory selection approach, seeking input from farmers and refining breeding targets as necessary. Farmers communicate their preferences and feedback through the farmer evaluation sheets, helping breeders fine-tune their targets and develop varieties that meet farmers’ needs.
Another key element of the on-farm trials is that they help assess breeding progress in farmers’ fields in terms of crop productivity and return on investment.
CGIAR has launched a pilot program in Zimbabwe’s Mbire and Murehwa districts to promote agroecological solutions, with CIMMYT as a key partner. The initiative aims to develop sustainable farming practices by addressing challenges like pest outbreaks, drought, and access to quality seeds. CIMMYT’s involvement includes introducing innovative technologies such as demonstration plots and seed fairs, designed to enhance agricultural resilience and sustainability in the region. This collaborative effort seeks to empower local farmers and create a more sustainable agricultural system in Zimbabwe.
