Cosmas Chachi, a 46-year-old businessman, owns Triple Blessing Supermarket in Zambia’s Luwingu District. In 2000, Cosmas identified an opportunity to address the growing demand for fresh fish in his community and started selling the product in his local area. Like many rural entrepreneurs, Cosmas faced initial challenges such as unreliable supply chains, insufficient cold storage, and limited access to financing, all of which prevented him from meeting the rising demand from local customers. Undeterred, Cosmas embarked on a transformative journey into aquaculture.  

The turning point for Cosmas occurred in April 2023 when he participated in a training program on integrated aquaculture under the aegis of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, led by CIMMYT. The training implemented by the International Water Management Institute (IWMI), one of the key implementing partners of the project, emphasized sustainable intensification and equipped Cosmas with advanced skills in sustainable feed management, water quality control, efficient harvesting methods, and business management, among other areas.

“The training equipped me with expert knowledge in aquaculture management and skills to design and operate efficient fishponds,” Cosmas said. 

With his new-found expertise, Cosmas upgraded three of his existing fishponds and built six more, each measuring 13×15 meters. To meet customer demand, he introduced a strategic stocking system, staggering the placement of 1,000 fingerlings across his nine ponds. This innovation ensured consistent fish supply even during Zambia’s annual fish ban. “By stocking and harvesting my ponds, I can maintain a steady supply even during the national fish ban when local supply decreases because some other farmers who supply my supermarket depend on fish from natural water bodies,” Cosmas shared.  

Creating livelihoods and building resilience

Cosmas’ aquaculture enterprise has become an economic engine in his community, employing 25 permanent workers, primarily local youth, and offering seasonal jobs to 12 more. For Emmanuel Makumba, a shop attendant at Triple Blessing supermarket for the last eight years, the opportunity has been life changing. “The job at the supermarket helped me relocate from my village, build my own house, and send my children to a private school,” said Emmanuel. 

In June 2024, his business received a significant boost with the installation of a 15-ton cold storage facility, funded by IWMI through the AID-I project. The upgrade significantly reduced post-harvest losses and enhanced Cosmas’ fish storage capacity. It ensures a steady supply for his business and the farmers he supports, strengthening the local aquaculture value chain.  

“In the past, we could only purchase 50 to 100 kilograms (kg) of fish at a time, selling it at US$ 2.50 per kg,” Cosmas shared. With the new cold storage facility, Cosmas can now buy and store up to 700 kg of fish per harvest without the risk of spoilage. The effort not only secures a reliable supply for his business but also creates a dependable market for local consumers, fostering growth and sustainability in the region’s aquaculture sector.  

A ripple effect of progress: Expanding aquaculture for community impact

Today, Cosmas’ success goes beyond his supermarket. He owns a thriving restaurant, offering customers a unique dining experience with fresh fish from his ponds. “The training I received during the AID-I workshops helped me transform my passion for aquaculture into a successful business. Now, in addition to the supermarket, I own a popular restaurant and outdoor fishponds, offering customers a unique dining experience,” he said.

Building on his business success, Cosmas has further expanded his impact by transforming his fishponds into practical classrooms, offering free, hands-on training to aspiring fish farmers. Over the past year, he has trained 50 farmers in sustainable aquaculture best practices.  

As more farmers in Luwingu adopt these practices, local food security improves, and income streams diversify. Cosmas’ leadership is stabilizing the community’s food supply and improving diets with nutrient-rich fish. This aligns with AID-I’s broader goal to promote sustainable and scalable agricultural models.  

By September 2024, the AID-I project, through IWMI’s efforts, had supported 297 fish farmers with training, market linkages, and tools for success across Northern and Luapula Provinces: creating a ripple effect of progress and also addressing Zambia’s fish supply and demand gap. The project empowers communities to adopt innovative and sustainable aquaculture practices, driving growth in fish production and ensuring a more reliable supply to meet the needs of a growing population. As fish is a critical source of protein and essential nutrients, fostering a sustainable aquaculture sector is vital for supporting Zambia’s food security and nutritional goals.  

Cosmas’ journey exemplifies the power of partnerships, innovation, and resilience in driving community progress. It underscores the potential for a robust aquaculture sector in Zambia, where challenges spur solutions and success benefit entire communities. Through AID-I’s comprehensive interventions, Cosmas’ story of transformation offers a vision for sustainable development in rural Zambia, led by innovation and community empowerment.

Atubandike: Breaking down gender barriers in Zambia’s agricultural advisory services

Written by dmedina on . Posted in Blogs.

Zambia’s agricultural sector has long grappled with significant gender disparities, particularly in rural areas where women often face unique barriers to accessing essential agricultural information. Despite playing a critical role in food production, women remain significantly underrepresented as agricultural extension agents, a trend that persists not only in Sub-Saharan Africa (SSA) but also globally. Changing this narrative demands a coordinated effort from government, non-governmental organizations (NGOs), the private sector and communities to challenge deep-rooted stereotypes about women’s roles and capabilities in agriculture.[1]

The Atubandike approach, a key part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, addresses these challenges head on. Through initiatives focusing on gender-inclusive seed systems and agricultural advisories on climate-smart agricultural (CSA) practices, Atubandike is actively working to increase women’s representation among Zambia’s agricultural advisors. By equipping communities with inclusive advisory services and training women and men digital champions, Atubandike is paving the way for a more equitable agricultural future.

This blog delves into the gender biases uncovered during recent community consultations organized by the AID-I Atubandike team in Zambia’s Southern Province across various rural districts, held in November 2023, as well as July 2024.[2] These consultations, aimed at addressing gender and youth stereotypes in agriculture, highlighted Atubandike’s initiatives to reshape the agricultural landscape for women and marginalized groups.

Community dialogues reveal deep-rooted gender biases in advisory access and spring up encouraging perspectives for female advisors

Staying true to the name, Atubandike—meaning “Let’s Chat” in Tonga—the AID-I team implementing the initiative, facilitated community discussions with over 1,700 farmers in Zambia’s Southern Province to explore underlying gender challenges in agriculture. Through these conversations, deep-seated gender biases emerged as a significant barrier. Many female agricultural advisors contend with cultural stereotypes that undermine their leadership and technical skills. As one participant noted, “Women are mostly seen as subordinates to men, so it is only natural that female agricultural advisors are viewed as less capable.” Such remarks highlight the difficult path women often tread to establish their authority in agricultural roles. Unfortunately, this bias isn’t limited to men; some female farmers also expressed a preference for male advisors, sharing the belief that “a fellow woman cannot provide valuable information.”

Studies on agricultural extension services confirm that  gender disparities in advisory roles severely  limit women farmers’ access to timely, high-quality  information in SSA and other developing regions. This, in turn, impedes their ability to boost productivity and provide for their families. [3] Agricultural Advisory Services (AAS) are often designed with men as the primary beneficiaries, overlooking the need to make services more accessible and relevant to women. The dominance of male extension agents further exacerbates this issue, especially in societies where cultural norms restrict interactions between women and men outside their immediate family. These societal norms reinforce traditional gender roles, undermining the effectiveness of women as agricultural advisors. As a result, women are often excluded from opportunities that would enable them to fully participate in, and benefit from, agricultural development. This exclusion not only limits their potential but also perpetuates poverty and inequality.

On a positive note, a more nuanced perspective also emerged during the discussions. Some community members recognized the unique strengths that female advisors bring to their work. As one participant observed, “Female advisors are more careful and easier to talk to,” noting that women often prioritize technical knowledge, while men may base advice more on personal experience. This insight provides a glimmer of hope: with increased exposure and trust, farmers could become more receptive to female advisors, recognizing their effectiveness alongside their male colleagues.

In some settings, women farmers even prefer female advisors, feeling more comfortable discussing issues and having a greater sense of shared experiences. According to a study conducted in Mozambique, women farmers were more likely to be reached as well as learn when agricultural content was delivered by female advisors. [4] This highlights the potential impact of gender-sensitive approaches in improving the efficacy and accessibility of advisory services for women.

Achieving equal footing for women in AAS requires addressing a broader range of barriers. This not only entails efforts to recruit and retain women in these roles but also providing equal opportunities for education and training, as well as developing explicit policies to safeguard women advisors from gender-based discrimination.

Breaking barriers: How Atubandike is transforming AAS

The goal of the Atubandike approach is to identify, understand and dismantle entrenched gender barriers in agriculture. By adopting an innovative and inclusive strategy, this initiative equips both men and women with the tools they need to become digital champions and agricultural advisors, playing pivotal roles in their communities. With a deliberate focus on increasing female representation, Atubandike ensures that at least 50% of these champions are women, amplifying their visibility and influence in the sector.

Central to Atubandike is its emphasis on community engagement through a feedback-driven process. This approach facilitates open dialogue among community members, urging them to confront existing social biases and develop practical solutions. Through these discussions, the initiative fosters collective action aimed at promoting gender equity and social inclusion. Additionally, Atubandike provides comprehensive training on gender, diversity, and inclusion, equipping its digital champions not only with technical knowledge but also with the skills required to challenge and navigate gender biases effectively.

One of the initiative’s most transformative elements is its focus on diverse role models. By ensuring that half of its village-based digital champions are women, Atubandike boosts their digital literacy, agricultural expertise, and standing as leaders and role models within their communities.[5] These women are featured prominently in digital content and on talk shows, reshaping perceptions of women as agricultural leaders and breaking down longstanding negative narratives that have historically sidelined them.

Sustaining Atubandike’s momentum: Community-driven support for female advisors

Community members balanced the discussions by proposing valuable insights and strategies to overcome the deeply rooted stereotypes that challenge female agricultural advisors. Raising community awareness about the value of female advisors emerged as a crucial approach to fostering their acceptance. As one participant emphasized, “More training on gender norms is essential so that the community can become more open-minded.” Others argued that establishing trust in female advisors from the outset could empower them as agents of change: “If we begin by placing our trust in female agricultural advisors, we can encourage other communities to do the same.”

Community leaders were urged to facilitate meetings to address any disrespect toward agricultural advisors, irrespective of gender. A farmer emphasized the necessity of mutual respect, stating, “The community should be encouraged to work cooperatively with their agricultural advisors.”

Participants also highlighted that agricultural advisors must actively demonstrate their competence to build trust. In one community, it was stressed that both female and male advisors “must practice the agricultural technologies they promote so that people can have faith in their competence.” Additionally, participants suggested that advisors wear uniforms to clearly distinguish their professional roles, signaling their commitment to serving the community in an official capacity.

A model for inclusive agricultural development

Atubandike transcends the role of a conventional agricultural advisory initiative; it stands as a beacon of inclusive development, extending its impact across Zambia and setting a model for the region. By delving into the roots of gender bias and driving practical, community-led solutions, Atubandike aligns with the AID-I project’s mission of “delivering with a difference.” Through empowering female digital champions and fostering dialogues on social equity, Atubandike demonstrates that meaningful change is both attainable and sustainable. As a testament to AID-I’s dedication to equitable innovation and resilience, Atubandike is not only reshaping gender norms in Zambia but is also establishing itself as a blueprint for inclusive impact across Southern Africa’s agricultural landscape.

How Atubandike dialogues are redefining gender and youth inclusion in Zambian agriculture

Written by mcallejas on . Posted in Blogs.

Women and youth are essential drivers of agricultural and economic resilience in Zambia’s rural farming communities. However, they frequently encounter significant barriers such as restrictive social norms and inadequate access to vital resources which hinder their ability to participate fully in the economy.

Recognizing the critical roles of women and youth in shaping the present and future of Zambian agriculture, the ‘Atubandike’ approach, under CIMMYT’s USAID-funded Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub project, has been actively engaging with communities to address systemic barriers faced by these groups. This initiative combines digital tools with face-to-face interactions, creating spaces where community members can share their stories, challenges, and questions to co-create solutions.

Atubandike, which means ‘let’s have a conversation’ in the local Tongo language, was launched in Zambia in 2023 as an advisory service. The model represents a scalable, community-led approach that empowers marginalized groups, including women and youth, as active contributors and leaders in agriculture. With each interaction building upon the previous one, this ongoing work advances the broader mission of fostering inclusivity and resilience across Zambia’s agricultural sector.

To uncover and tackle the structural barriers faced by women and youth, the Atubandike team recently engaged over 1,700 farmers across 14 communities in Southern Zambia, gaining critical insights into the biases that persist in rural areas.

Stereotypes and structural barriers

The community conversations highlighted generational divides and deeply rooted stereotypes that cast youth as disengaged or disinterested in farming. Older community members opined that young people are more drawn to urban lifestyles and reluctant to take on the demanding labor associated with agriculture. One elderly farmer said: “Many youths prefer a comfortable lifestyle and quick money. They don’t have the patience for the hard work farming requires.”

In contrast, younger participants shared that this perception overlooks the genuine obstacles they face such as limited access to land, financing, training, and mentorship opportunities. They emphasized that their lack of involvement often stems from these barriers rather than a lack of motivation.

The consultations also underscored pervasive gender norms that limit women’s roles in agriculture. Despite their significant contributions to household food security, female farmers are often relegated to secondary roles, focusing on ‘women’s crops such as groundnuts, while men cultivate staple crops such as maize and cash crops such as soybean. A participant shared, “The community always perceives men as the real farmers because they are considered the heads of the household.” This perception frequently limits women’s access to critical resources and their decision-making power within the agricultural sphere.

However, through Atubandike’s sessions, communities are beginning to confront these entrenched norms, shedding light on the vital contributions of women and youth in agriculture. This shift is laying the groundwork for a more equitable approach, where both men and women, young and old, are recognized as essential to farming success and household resilience. As these conversations grow, Atubandike is paving the way for solutions that promise meaningful and lasting change for both women and youth in agriculture.

Community-driven solutions

  • Building youth capacity through skills and leadership: Many community members expressed a strong desire to see more youth involved in agricultural activities, emphasizing the importance of hands-on training. “We need to get the youth involved in actual farming [tasks] such as irrigation and crop management. It keeps them busy and teaches them valuable skills,” shared one local leader.

To support this vision, Atubandike is training young community members as digital champions, equipping them with both technical expertise and leadership skills that allow them to mentor their peers and encourage youth participation in agriculture. These digital champions not only extend the reach of Atubandike’s initiatives but also serve as relatable role models, inspiring other young people to engage in agriculture as well as see it as a viable and rewarding path.

  •  Towards a more inclusive future for Zambian agriculture
    The Atubandike initiative – by fostering open community dialogue, empowering digital champions, and promoting household-level collaboration – lays the foundation for a more inclusive future for Zambian agriculture. As each community engagement builds momentum, CIMMYT, through the AID-I project, creates a cycle of empowerment and growth that ensures women and youth are not only heard but also empowered to lead.

Amidst the challenges of erratic weather patterns and economic constraints, building resilience through cross-generational and gender-inclusive collaboration is crucial. Atubandike is addressing these geographic and social challenges and paving the way for a future where every farmer, regardless of age or gender, plays a pivotal role in Zambia’s agricultural success.

Atubandike (“Let’s Chat”)

Written by dmedina on . Posted in Uncategorized.

Atubandike (“Let’s Chat”) is a phygital platform co-developed by CIMMYT, Viamo, and farmers to transform agricultural information channels in Zambia’s Eastern and Southern Provinces. Through the toll-free 667 platform, 4,000 farmers – more than 50% of whom are women – access an interactive voice response (IVR) menu powered by a Viamo Database (see infographic). The platform delivers timely and engaging pre-recorded messages on climate-smart agriculture (CSA); enables farmers to ask questions, which informs content for the platform’s biweekly “talk shows” (like radio shows but on a mobile phone); and provides a space for them to share their stories as “peer farmer experiences” on the platform.

(Infographic: Eugune Mumiah, Project Milieu Group)

Atubandike’s model involves farmers as co-creators, not merely recipients, of advisory content. Their contributions are curated by a content committee – with farmer, government, and scientist representation – before being published on the 667 platform. Village-based digital champions (50% women, 42% youth aged 18-29) play a crucial role in supporting farmers’ digital skills and promoting trust in digital advisory; they also act as intermediaries between farmers and CIMMYT to address time-sensitive farming questions immediately.

The Atubandike initiative mobilizes local communities to take collective action in challenging social norms that underpin digital access divides. Through community-driven efforts, digital champions are nominated and social changemakers selected to promote inclusive access to the platform.

Together, we are advancing awareness and uptake of CSA practices to boost agricultural productivity and climate change adaptation, using on-the-ground insights to continuously refine Atubandike’s services and ensure every farmer, across the spectrum of demographic groups, thrives in today’s dynamic agricultural landscape.

Buffering Climate Extremes in Zambia: The Essential Role of Delivery with a Difference

Written by dmedina on . Posted in Blogs, Features.

Dr Sieg Snapp is Program Director, Sustainable Agrifood Systems, International Maize and Wheat Improvement Center (CIMMYT)

Climate change is upending weather patterns across Africa, presenting dire challenges for farming communities. In Zambia, the impact is particularly harsh. Agriculture is the lifeblood of the economy, with two-thirds of the country’s workforce employed in agriculture, and 78% of these workers are women.

The country faced a severe El Niño during the 2023/2024 season, causing a severe drought that devastated over 1 million hectares of cropland. The president declared it a national disaster. El Niño events typically result in catastrophic drops in crop yields, often reducing maize harvests by 30-40%. These events not only impact food security but also hinder economic growth, with the agricultural sector’s contribution to Zambia’s GDP dropping from 9.4% to 3.39%.

The devastating El Niño-induced drought in Zambia is starkly illustrated by the story of Melody Limweta, a 31-year-old farmer. She and her husband, Collins Manenekela, have seen their already fragile livelihood pushed to the brink by severe water shortages. Typically, they rely on dry season gardening and small-scale farming, including raising chickens, during the rainy season. However, the drought has dried up local water sources, making gardening impossible and sharply reducing their income. The couple’s practice of planting maize in the same field each year with recycled seeds and traditional methods has worsened their situation, as the El Niño-induced rainfall deficits have led to poor yields. Their primary source of food and income has withered in the field due to insufficient rainfall.

A consortium of partners led by the International Maize and Wheat Improvement Center (CIMMYT) have joined together as a rapid delivery hub for these challenging times, providing vital support to rural communities and families such as Melody and Collins. Farmers have a strong voice in this unique delivery mode. With support from the people of the U.S. government, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) is promoting access to drought-tolerant crops, climate-busting and nutritious legume seeds, agricultural advice and early warning systems to combat climate change. AID-I provides critical support to ensure that millions of smallholder farmers in the Haut-Katanga region of DR Congo, Malawi, Tanzania, and Zambia have access to information and innovations needed for gains in food production that help buffer drought, flood and rising food, fuel, and fertilizer prices.

Speed and Scale: planting drought-tolerant maize

The idea of the ADI-I as a rapid delivery hub is to make available innovations and agronomic information at both speed and scale. Traditional farming methods and crops struggle with climate extremes like El Niño, which bring prolonged dry spells and heatwaves. Drought-tolerant maize varieties offer a promising solution by enhancing agricultural resilience. These adapted maize varieties yield 30-50% more than traditional ones under drought conditions, as demonstrated in recent trials during El Niño periods. However, these improved varieties are only useful when in farmers’ hands.

Working with local partners, AID-I is scaling drought-tolerant maize varieties to help Zambian farmers manage unpredictable weather patterns. In the 2023/2024 season, approximately 27% of Zambia’s smallholder farmers saw a significant boost in their maize harvests, benefiting over 900 thousand people in drought-affected regions, owing to drought-tolerant maize varieties. Over six hundred thousand households planted drought-tolerant maize varieties and produced 235 thousand metric tons of maize, accounting for 19% of Zambia’s maize production in the 2023/2024 season. This is huge return, as only 10% of the maize-growing area being planted with these resilient varieties.

Crop diversification for family nutrition

In addition to drought-tolerant maize, studies indicate that diversifying with legume crops is crucial for managing weather extremes, especially droughts and for improving soil health. Planting legumes helps spread the risk with varied planting and harvest times, cushioning the impact of erratic rainfall on crop yields. Women can feed their families due to crops like peanuts that mature early and need less rainfall. The benefits are sustained over time, as combining legumes with cereals improves overall nutrition and soil health, even amid unpredictable weather.

To support this effort, AID-I linked over 2,000 farmers to high-quality seeds for groundnuts (peanuts) and soybeans. On average, each household harvested about 80 kg of groundnuts and 175 kg of soybeans, earning roughly $75 and $58, respectively. Collectively, this initiative produced about 205 metric tons of these crops, accounting for around 14.3% of Zambia’s total production in the drought-stricken season. Farmers had a voice in choosing which crop varieties to grow through a feedback system called ‘let’s chat’ where with an ordinary flip phone farmers could call in and learn from their neighbour’s recorded commentary and testimonials. For the first time ever, farmers could provide comments on which crops they preferred, providing a lifeline of communication with agritraders, government and agricultural advisors.

A recent assessment found that Zambian women made up 60% of those benefiting from cowpeas, 65% from groundnuts, 62% from soybeans, and 36% from drought-tolerant maize.

Forewarned is forearmed – early-warning systems

Weather information services, especially early warnings about upcoming droughts, are vital for helping farmers adapt to climate change. Accurate and timely weather forecasts enable farmers to make informed decisions about planting, resource use, and crop management. This reduces losses and boosts productivity. Research shows that access to climate information can significantly increase crop yields and incomes, with some farmers experiencing up to a 66% boost in yields and a 24% rise in income.

The forecast of an El Niño for the 2023/2024 season prompted an early warning campaign to raise awareness about the hazards associated with El Niño and provide response mechanisms for smallholder farmers.  AID-I used an Interactive Voice Response platform hosted by Viamo, a global social enterprise that uses mobile technology to connect people to valuable information and services. This rapid El Niño advisory campaign reached over 500 thousand farmers, with 60% male and 40% female listeners, and 93% of them under 35 years old. The campaign provided crucial advice on planting schedules, drought-resistant crops, and water-saving techniques.

Additionally, AID-I established demonstration sites that showcased effective winter crop production methods and introduced over 2,000 farmers to innovative agricultural practices. These interventions significantly improved farmers’ ability to respond to the drought.

Looking ahead

Scaling the adoption of drought-tolerant maize, improved legumes, and timely advisories is vital to protecting Zambia’s agriculture from climate extremes. The introduction of an AID-I-supported digital advisory campaign in September 2023 was a turning point for farmers like Melody and Collins. By engaging with the content, they learned about improved seeds, crop rotation, and better agronomic practices, which helped them cope with ongoing challenges and protect their resources. Initiatives like this can help families on the margins survive and rebuild agricultural production faster.

AID-I’s impact on families like Melody and Collins shows that investing in rapid delivery hubs is crucial for building resilience in farming communities. Expanding such initiatives will ensure more smallholder farmers have access to the innovations needed to maintain or increase food production amid climatic challenges.

Additionally, studies by organizations like Springer and the American Geophysical Union highlight the importance of integrating rapid delivery hubs into mainstream agricultural programs to enhance climate resilience and food security. Therefore, this necessitates an open call for international development allies—including donors, governments, NGOs, and businesses—to incorporate initiatives like AID-I into broader agricultural agendas, essential for fostering resilience and ensuring the future stability of farming communities in Zambia and beyond.

Unlocking Zambia’s maize potential through crop diversity

Written by Julian Bañuelos-Uribe on . Posted in Publications.

While maize is the primary staple food crop in Zambia, its productivity on farmers’ fields reaches on average only about 20 percent of what it could achieve with good agronomic practices. Some reasons for this inefficiency are use of traditional varieties, low fertilizer use, and ineffective weed and pest control.

Closing the gap between potential and realized yields would have major benefits for farmers in Zambia, both in terms of income and food security at the household and national levels. One possibility to increase maize productivity is by increasing crop diversity through the inclusion of legumes in maize-based farming systems. This could be done through intercropping, growing legumes in the rows between maize plants, or crop rotations and alternating maize and legumes in the same field from season to season.

CIMMYT scientists, along with collaborators from the Zambia Agriculture Research Institute (ZARI) and the University of Zambia’s School of Agricultural Science, set out to determine which cropping systems might lead to increased productivity for maize farmers in Zambia and their results were published in the journal Field Crops Research.

“There is great potential in Zambia to increase yields to help ensure food security,” said Mulundu Mwila, PhD candidate and scientist at ZARI. “We wanted to determine the cropping systems that offered the most benefits.”

Setting up the study

For this research, ZARI and CIMMYT scientists established maize-based cropping systems trials, comprising maize monocropping, and maize-legume rotations and intercrops under both ‘conventional’ tillage, and Conservation Agriculture, across 40 farms in a variety of agroecological zones in Zambia.  The team also conducted household surveys in the same communities hosting the on-farm trials to determine the share of households with enough cultivated land to benefit from the tested cropping systems.

Researchers found that the tested cropping systems produced more maize per hectare compared to non-trial host farms in the same region. The greatest positive effect uncovered was that maize-legume rotations in Zambia’s Eastern Province had the potential to increase maize yield by 1 to 2 tons per hectare, per growing season. “The Eastern Province trials showed better results because of stable and adequate rainfall amounts and distribution and because of using groundnut as a rotation crop,” said Mwila.

Researchers attributed the small effect of legumes on maize yield in the Southern Province to low levels of biomass production and nitrogen fixation, due to low and erratic rainfall, and to low residue incorporation because of livestock grazing. Conversely, the small effect of legumes on maize yield in the Northern Province might be attributed to the high rainfall amount in the region, leading to high rates of leaching of residual nitrogen during the growing season as well as the use of common beans as the preceding crop.

Finding the right amount of land

With evidence showing the potential benefits of maize-legume rotations, the availability of land is a constraint for small farms across sub-Saharan Africa, thus it is important to quantify the land area needed for farmers to implement maize-legume rotations.

“Our findings match prior research showing the benefits of maize-legume rotations in Eastern Zambia” said Silva. “However, implementing maize-legume rotations remains a challenge for many smallholders due to small farm sizes.”

Nearly 35, 50, and 70% of the surveyed farms in the Northern, Eastern, and Southern Provinces, respectively, had enough land to achieve the same level of maize production obtained on their farm with the yields of the maize-legume rotations tested in the on-farm trials. “With our findings showing increased maize yields, and our efforts to determine the amount of land needed for food and nutrition security at household level, the next steps can be to facilitate methods to disseminate this information to policy makers and to farmers that have enough land area to benefit from diversified cropping systems,” said Silva.

For farmers with not enough land to reap the benefits of maize-legume rotations, intercropping legumes within the maize has shown promising results. The researchers also call for further research to specify the contributing factors to small farms not seeing benefits from maize-legume rotations.

Building global capacity to combat wheat blast

Written by Julian Bañuelos-Uribe on . Posted in News.

Researchers and experts from 15 countries convened in Zambia, between 4-15 March 2024, for an international training on wheat blast disease screening, surveillance, and management.

Wheat blast, caused by pathogen Magnaporthe oryzae pathotype triticum, is threatening global wheat production especially in warmer and humid regions. The disease was first observed in Parana state of Brazil in 1985 and subsequently spread to Bolivia, Paraguay, and Argentina. Outside of South America, wheat blast incidences were recorded for the first time in Bangladesh in 2016 and in Zambian wheat fields in 2018.

To mitigate the impact of this potential plant pandemic, the Zambia Agriculture Research Institute (ZARI), in collaboration with CIMMYT and other partners, organized a comprehensive training for building research capacity and raising awareness within the local and international community, especially in at-risk countries.

“This collaborative effort, supported by various international partners and funders, underscores the importance of global cooperation in addressing agricultural challenges such as wheat blast. The objective of the training was to empower researchers with knowledge and tools for enhanced wheat production resilience in regions vulnerable to this destructive disease,” said Pawan Kumar Singh, principal scientist and project leader at CIMMYT. Singh collaborated with Batiseba Tembo, wheat breeder at ZARI-Zambia, to coordinate and lead the training program.

Thirty-eight wheat scientists, researchers, professors, policymakers, and extension agents from countries including Bangladesh, Brazil, Ethiopia, India, Kenya, Mexico, Nepal, South Africa, Sweden, Tanzania, United Kingdom, Uruguay, Zambia, and Zimbabwe convened at the Mt. Makulu Central Research Station in Chilanga, Zambia.

“Wheat blast is a devastating disease that requires concerted efforts to effectively manage it and halt further spread. The disease is new to Africa, so developing capacity amongst country partners before the disease spreads more widely is critical,” said Tembo.

Highlights from the training: discussions, lab exercises, and field visits

During the training, participants engaged in lectures, laboratory exercises, and field visits. There were insightful discussions on key topics including the fundamentals of wheat blast epidemiology, disease identification, molecular detection of the wheat blast pathogen, isolation and preservation techniques for the pathogen, disease scoring methods, disease management strategies, and field surveillance and monitoring.

The course also provided practical experience in disease evaluation at the Precision Phenotyping Platform (PPP) screening nursery located in Chilanga research station. This involved characterization of a diverse range of wheat germplasm with the aim of releasing resistant varieties in countries vulnerable to wheat blast. Additionally, participants undertook field visits to farmers’ fields, conducting surveillance of wheat blast-infected areas. They collected samples and recorded survey data using electronic open data kit (ODK) capture tools.

“The killer disease needs to be understood and managed utilizing multi-faceted approaches to limit the expansion and damages it can cause to global wheat production. The Bangladesh Wheat and Maize Research Institute (BWMRI) is willing to share all the strategies it deployed to mitigate the effect of wheat blast,” said Golam Faruq, BWMRI’s director general.

Participants visited seed farms to gain practical insights into seed production processes and quality assurance measures. These visits provided first-hand knowledge of seed selection, breeding techniques, and management practices crucial for developing resistant wheat varieties. Participants also visited research sites and laboratories to observe advanced research methodologies and technologies related to wheat blast management. These visits exposed them to cutting-edge techniques in disease diagnosis, molecular analysis, and germplasm screening, enhancing their understanding of effective disease surveillance and control strategies.

“The training and knowledge sharing event was a significant first step in developing understanding and capacity to deal with wheat blast for partners from several African countries. It was wonderful to see the efforts made to ensure gender diversity among participants,” said Professor Diane Saunders from the John Innes Centre, UK.

Rekindling and revitalizing chicken farming in Zambia

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

In Zambia, women play a major role in agriculture and constitute much of the labour force for cash crop production and home consumption. In Chilayabale area of Chongwe district in Zambia, a group of women founded Tuyumepo Women Cooperative with support from Zambia’s Farmer Input Support Program (FISP). Initially focused on commercial soya milk and okra coffee production, members shifted to poultry production in 2022, which they had identified as a game changer. They successfully developed a business plan that was funded by the World Food Programme, providing 150,000 Kwacha (USD 5,600) for broiler chicken production. Part of the funds were used to construct a poultry house and acquire 200-day-old chicks.

However, their excitement soon turned into despair. What had appeared a very profitable venture turned into a loss-making enterprise. The group could not understand why the birds, despite being provided with the required feed and vaccines, had a high mortality rate. They eventually abandoned the broiler production business.

Despite setbacks, the group’s determination remained strong. Like many other smallholder poultry producers in Zambia; they recognized the immense potential of chicken farming. But they were constrained by various production challenges such as limited access to improved chicken breeds or day-old chicks, limited access to key vaccines, basic chicken health services, quality feed, and essential extension services. These challenges led to poor productivity, high mortalities and underperformance of the enterprise and the chicken value chain in general.

However, a ray of hope emerged earlier this year with the arrival of the Southern Africa Accelerated Innovation Delivery Initiative – Livestock (AIDI-L) in Bimbe. A sensitization meeting organized by AIDI-L reignited their enthusiasm for poultry farming. What stood out was AIDI-L’s commitment not only to provide starter kits but also to offer training on best poultry farming practices. This renewed optimism prompted members of the Tuyumepo Women Cooperative, along with other farmers in the area, to attend training sessions on poultry production at Kambekete Camp, Chongwe District, Lusaka Province on 8 April 2024.

The participants were trained on general poultry production and marketing, and how to effectively train others on the same in the targeted districts. The target trainees were commercial poultry farmers, brooders, and lead farmers. Each training was attended by about 30 participants comprising lead farmers, brooders, and commercial poultry farmers in the district.

Led by Venture37, the International Livestock Research Institute (ILRI), and local government livestock officers, these sessions covered various aspects of poultry farming, from chicken health and housing to marketing and business development.

To many, the training was an eye-opener.

“I have just realized that our broilers were dying not because of diseases, but because of poorly ventilated housing structure,’ stated Annie, a brooder and a lead farmer in the area.”

With the newfound partnership, the cooperative plans to acquire 200 chicks.

Elizabeth Mwalusoke, a farmer from Lobolola Village, Chongwe District, had long recognized the potential of poultry farming but lacked the necessary knowledge and skills on good poultry husbandry, such as appropriate housing, hygiene, pests and diseases, and their control. She was lucky to have attended the AIDI-L sensitization meeting at Bimbe and Kambekete Camp in February 2024.

“This project will definitely help us develop our chicken business.”

The venture is even more appealing to Elizabeth, who owns two hectares of farmland, ideal for chicken rearing but not for large livestock farming.

For the ambitious Festus Nchenesi, the initiative provides opportunities for expanding and diversifying his commercial chicken enterprise. Nchenesi, a retired accountant, started with 100 broilers in 2017 at his one-hectare farm after relocating from Chongwe Town. He has steadily increased the flock to 300 birds but would have kept more if it had not been for the challenges he has encountered.

His attempts to venture into improved chicken farming failed due to a lack of knowledge of chicken brooding.

“I would have over 10 chicken brooding with at least 10 eggs each. But once one of the chickens had chicks, all the others would abandon their eggs and start fighting to care for the few hatched chicks. To circumvent this, I acquired a 32-egg capacity incubator, hoping not only to build my flock but also to brood and supply to other farmers in the area. However, the 6,000 Kwacha incubator could only hatch 3-5 eggs per incubation for reasons the supplier could not even explain. I am very optimistic that the project will turn my fortunes around. My target is to have at least 1,000 improved chickens because of their good marketability and returns and reduce the broiler flock.”

Others like retired Captain Ceasar Chibiye, a commercial poultry farmer in Kapiri District, Central Province, are more than ready to seize the market linkage opportunities that the project is bringing, being one of the major hurdles the farmers have been grappling with in the chicken value chain.

Laurence Ochieng, an ILRI veterinarian, was impressed with the enthusiasm and passion of the participants. He was optimistic that the project will greatly revitalise chicken farming in target regions.

“Most of the attendees seem to be involved in village chicken rearing.  For instance, those from Shamutinta village will benefit from disease control measures such as Newcastle disease vaccination as this seems to be their greatest challenge in rearing the birds to productive stage. Most of them had lost their flocks due to diseases, predominantly Newcastle and fowl pox.”

Esther Omosa, ILRI nutrition specialist, sensitized the participants on the importance human nutrition, promising to conduct a detailed TOT training on high impact nutrition sensitive interventions that need to be implemented at community level to prevent malnutrition.

Funded by the United States Agency for International Development, the two-year AIDI-L project aims to help 15,000 small-scale, poultry-keeping households acquire increased access dual-purpose backyard village chicks; and reduce morbidity and mortality of poultry byfacilitating access to, and vaccination of, poultry to key economically impactful diseases such as Newcastle Disease. With a holistic approach that addresses both production and market challenges, the project holds promise for revitalizing chicken farming in Zambia. Thousands more households will be reached through media advisories on the importance of vaccinations and improved husbandry practices for chickens.

It’s time to scale: Emerging lessons from decades of Conservation Agriculture research in Southern Africa

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

For decades, smallholder farmers in Southern Africa have battled the whims of a changing climate—from withered crops to yield reductions and looming food insecurity concerns. And the outlook is not improving. Based on the latest available science, the sixth assessment report of the Intergovernmental Panel on Climate Change (IPCC) reaffirms the projected negative impacts of climate change on livelihoods in Southern Africa.

Conservation Agriculture (CA) has been considered as an important step to make smallholder farming systems climate smart and resilient. The principles of CA are simple yet potent: minimal soil disturbance, crop cover, and diverse rotations, which tend to have lasting implications on rebuilding soil health, conserving moisture, and nurturing a thriving ecosystem. A strong evidence base from on-farm and on-station trials show that CA has the potential to build the adaptive capacity and resilience of smallholder farming systems to climate stress.

Yet, despite the positive results, significant scaling gaps remain. Key questions arise on what can be done to turn the tide, scale, and encourage uptake. What institutional, policy and economic incentives would enable scaling? Could mechanization be the missing link? The Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA) project responds to these questions. With funding from the Norwegian Agency for Development Cooperation (NORAD) and implemented by the International Institute of Tropical Agriculture (IITA), and CIMMYT, the ACASA project goes beyond the narrow focus on promotion and technology delivery of past and ongoing interventions on CA in Southern Africa.

ACASA was designed to help stakeholders gain deeper understanding of the interactions between the socio-economic, biophysical, and institutional constraints and opportunities for adoption of CA practices. To do this, the project has undertaken extensive surveys aimed at understanding incentives, drivers, and barriers of CA adoption across Zambia, Malawi, and Zimbabwe.

Dialogues for change

In December 2023, CIMMYT collaborated with IITA and the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development of Zimbabwe to convene a highly engaging, reflective, and learning meeting, with the participation of government representatives, the private sector, and research institutes, among others. The primary objective was to share valuable insights accumulated over years of research and development on conservation agriculture in southern Africa. These insights are a result of collaborative efforts in social science, scaling, and mechanization work by CIMMYT, IITA, and extension and research partners in Malawi, Zambia, and Zimbabwe. Conversations centered on tracing the historical pathway of CA, leveraging mechanization, and identifying key enablers to transform smallholder agriculture.

Tracing the pathway of conservation agriculture

For decades, CIMMYT has been a leading force in promoting Conservation Agriculture. From the early stages in the 1990s, CIMMYT introduced CA principles and practices through on-farm and on-station field days, to undertaking robust research on biophysical impacts and developing adapted technologies in collaboration with national and global partners. As this research progressed and matured, efforts were made to integrate and focus on understanding the social and economic factors influencing CA adoption, while recognizing the significance of enabling environments. To date, linkages with mechanization and other innovations promoting CA-friendly equipment have been strengthened, ensuring inclusivity and empowerment. Questions remain around policy and institutional innovations to nudge and sustain adoption. In a nutshell, there is scope to borrow tools and methods from behavioral and experimental economics to better study and facilitate behavioral change among smallholder farmers. This snapshot highlights global efforts, grounded in scientific evidence, farmer centric approaches, and collaborative partnerships.

Insights from the field

Described as a data and evidence driven process, a notable highlight was the detailed gathering and analytical efforts using a large multi-country household survey involving 305 villages and 4,374 households across Malawi, Zambia, and Zimbabwe. The main thrust was not only to harvest data but listen to farmers and better understand their context while deciphering their decision-making processes concerning CA adoption, across the three countries. A compelling and hopeful story unfolds from the results. The adoption of CA practices such as crop residue retention, minimum tillage, crop rotation, and intercropping is much higher than previously thought, highlighting a crucial need for better targeted surveys. Key enablers to strengthen adoption include access to CA extension, hosting demonstrations, and access to credit. In addition, age, and extension in the case of Zambia were identified as important drivers of the speed and persistence of adoption. Demand for mechanization is rising, which is key to address drudgery associated with CA and to raise production efficiencies. Key recommendations centered on the need for investments in a dense network of farmer-centric learning centers that allow for experiential learning, facilitating equitable access to mechanization, promoting private sector participation, and developing integrated weed management options as weeds remain the Achilles Heel of CA adoption in the region. [1]

Emerging lessons

A deep dive on the findings reveals critical considerations for the widespread adoption of Conservation Agriculture (CA). Firstly, weed-related labor challenges pose a significant obstacle, with around 75% of farmers in three countries citing weeds as the most constraining issue during initial CA adoption. Addressing this weed management challenge is essential, emphasizing the need for environmentally safe, non-chemical solutions as a research priority. Secondly, there is a noticeable gap between scientific research on CA and farmer practices, primarily attributed to limited technical knowledge. Bridging this gap requires innovative approaches to translate scientific information into practical, farmer-centered products. Thirdly, incentivizing CA adoption through complementary input support programs, like payments for environmental services, may encourage farmers, especially when private returns are not immediate.

Fourthly, strengthening extension systems is crucial to facilitate farmer learning and bridge the awareness-to-know-how gap. Lastly, investing in improved machinery value chains can alleviate high labor costs and drudgery associated with CA practices, with economic estimates suggesting farmers’ willingness to pay for machinery hire services. These insights collectively highlight the multifaceted nature of challenges and opportunities for scaling up CA adoption.

Moving forward

ACASA’s research findings are not just numbers — they are seeds of hope. They point towards a future where CA adoption among smallholder farmers can transform the breadbasket of the three African countries, and beyond. CIMMYT and its partners remain committed to continuous learning, refining their approaches, and working hand-in-hand with farmers to nurture the CA revolution.

It will not be a pipe dream to transform agriculture in Southern Africa through CA by cultivating seeds of resilience, one at a time. This is because the experience from the region suggests that with the right political will, it is possible to mainstream CA as a critical adjunct to climate-smart agriculture strategies and resilience building. This broader institutional and political buy-in is important since CA programming cannot succeed without sector-wide approaches to removing systemic constraints to technology adoption.  A classic example is the Government-backed Pfumvudza program in Zimbabwe, which has seen adoption of planting basins conditioned on receipt of input subsidies soar to more than 90%.

CIMMYT and China join forces to tackle wheat disease in Africa

Written by Julian Bañuelos-Uribe on . Posted in News.

While wheat acreage has been increasing across the whole of Africa, the sub-Saharan countries account for a significant proportion of the total growth and yield, equaling an area of approximately 3.1 million hectares and a production of more than 9 million tons. However, in recent years, Fusarium head blight (FHB) or head scab has become a major disease in the region, causing significant reductions in yield and quality due to the lack of resistant varieties and management tools.

In China, a successful wheat shuttle breeding program by the Chinese Academy of Agricultural Sciences (CAAS) and CIMMYT for improving FHB has existed since the 1980s. Additionally, CIMMYT and the Jiangsu Academy of Agricultural Sciences (JAAS) have provided an FHB screening station in Nanjing since 2019. With a wealth of experience in confronting the disease, this ongoing partnership can help to solve the challenges currently faced by farmers in Africa.

To this end, CAAS, JAAS, and CIMMYT organized a training workshop on FHB management for Africa, which took place with financial support from China Aid in Beijing and Nanjing, China, between 10 and 23 April 2024. Twenty participants, 45% of which were women, attended the workshop, with specialists in wheat breeding, pathology, seed quarantine, and other related fields at public institutions in Ethiopia, Zambia, and Lesotho.

“This is the first time China has worked with an international organization to conduct an agricultural training workshop for sub-Saharan Africa,” said Zhonghu He, CIMMYT distinguished scientist and country liaison officer in China.

Practical tools to target FHB

Experts from China and CIMMYT shared their successful experiences of FHB management, including breeding resistant varieties. The trainees benefitted from hands-on experience of FHB identification, disease screening (including inoculum preparation, inoculation, and scoring), mycotoxin quantification techniques, and wheat breeding.

At the end of the workshop, the participants were extremely pleased to observe the impressive progress made in China on wheat FHB both on breeding and disease control, and they expressed strong willingness to contribute to collaboration between Africa, China, and CIMMYT on more wheat breeding and research. Netsanet Bacha Hei from the Ethiopian Institute of Agricultural Research (EIAR) was impressed with the scientific and technical expertise provided in the training and mentioned that sub-Saharan Africa needs similar practical trainings to mitigate the threat of FHB. Similar opinions were echoed by Doreen Malekano Chomba from the Zambian Plant Quarantine and Phytosanitary Service (PQPS), who discussed the need to have an effective in-country surveillance and monitoring to assess and manage FHB in the region.

Xu Zhang, who heads the FHB research program at JAAS, is very appreciative of the collaborative work that has been going on for several decades between CIMMYT and China, highlighting that the workshop represents another step in understanding and managing FHB in sub-Saharan Africa and beyond, Zhang said, JAAS and CIMMYT has grown together through strong partnership.

“This training lays firm groundwork for future China-Africa-CIMMYT collaboration on mitigating the threat of FHB and improving wheat production and food security in sub-Saharan African countries,” said He.

Unanswered questions and unquestioned answers

Written by Julian Bañuelos-Uribe on . Posted in Publications.

Over the past few decades, Conservation Agriculture (CA) has moved from theory to practice for many farmers in southern Africa. CA is a system that involves minimum soil disturbance, crop residue retention, and crop diversification among other complimentary agricultural practices. One reason for its increasing popularity is its potential to mitigate threats from climate change while increasing yields.

However, there are limits to the adaptation of CA, especially for smallholder farmers. Challenges are both agronomic (e.g. lack of sufficient crop residues as mulch, weed control, pest and disease carryover through crop residues), socio-economic, and political (both locally and regionally).

A recent paper, Unanswered questions and unquestioned answers: the challenges of crop residue retention and weed control in Conservation Agriculture systems of southern Africa, published in the journal Renewable Agriculture and Food Systems in February 2024, led by CIMMYT and CGIAR scientists examines two specific challenges to more widespread CA adaptation: how to deal with trade-offs in using crop residue and finding alternatives to herbicides for weed control.

For crop residue, the two most prevalent actions are using leftover crop residue for soil cover or feeding it to livestock. Currently, many farmers allow livestock to graze on crop residue in the field, leading to overgrazing and insufficient ground cover. This tradeoff is further challenged by other multiple household uses of residues such as fuel and building material. The most common way to control weeds is the application of herbicides. However, inefficient and injudicious herbicide use poses a threat to human health and the environment, so the research team set out to identify potential alternatives to chemical weed control as the sole practices in CA systems.

“The answer to the question ‘how should farmers control weeds?’ has always been herbicides,” said lead author Christian Thierfelder, CIMMYT principal cropping systems agronomist. “But herbicides have many negative side effects, so we wanted to question that answer and examine other potential weed control methods.”

What to do with crop residue

Previous research from the region found that ungrazed areas had long-term positive effects on soil fertility and crop yields. However, it is common practice for many farmers in Malawi, Zambia, and Zimbabwe to allow open grazing after the harvest in their communities. Livestock are free to graze wherever they wander, which results in overgrazing.

“Open grazing systems help keep costs down but are very inefficient in terms of use of resources. It leads to bare fields with poor soil,” said Thierfelder.

While it is easy to suggest that regulations should be enacted to limit open grazing, it is difficult to implement and enforce such rules in practice. The authors found that enforcement is lacking in smaller villages because community members are often related, which makes punishment difficult, and there is an inherent conflict of interest among those responsible for enforcement.

Controlling weeds

Weeding challenges in CA systems have been addressed worldwide by simply using herbicides. However, chemical weeding is often not affordable and, sometimes, inaccessible to the smallholder farmers and environmentally unfriendly.

Using herbicides, though effective when properly applied, also requires a degree of specialized knowledge, and without basic training, this may be an unviable option as they may pose a risk to the health of the farmers. Thus, alternatives need to be identified to overcome this challenge.

Some alternatives include mechanical methods, involving the use of handheld tools or more sophisticated tools pulled by animals or engines. While this can be effective, there is the possibility of high initial investments, and intercropping (a tenet of CA) forces farmers to maneuver carefully between rows to avoid unintended damage of the intercrop.

Increasing crop competition is another potential weed control system. By increasing plant density, reducing crop row spacing, and integrating other crops through intercropping, the crop competes more successfully with the weeds for resources such as light, moisture, and nutrients. When the crop seed rate is increased, the density of the crops increases, providing more cover to intercept light, and reducing the amount of light reaching the weeds thereby controlling their proliferation.

A holistic approach

“What we learned is that many of the crop residue and weed challenges are part of broader complications that cannot be resolved without understanding the interactions among the current scientific recommendations, private incentives, social norms, institutions, and government policy,” said Thierfelder.

Continuing research into CA should aim to examine the social and institutional innovations needed to mainstream CA as well as strengthen and expand the research on weed control alternatives and focus on the science of communal grazing land management to enhance their productivity.

Sow, grow, and thrive: a pathway to improve cassava farming in Zambia

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

For decades, women farmers like Maureen Bwalya from the Musa camp in Kasama district of northern Zambia, have upheld the tradition of cultivating cassava on ridges. These small piles of soil created by hand hoes, 30-50 cm tall and 50 cm wide are intended to reduce water logging and facilitate cassava growth. But forming row after row takes a significant amount of physical labor. Establishing ridges follows a traditional practice known as chitemene, a Bemba word which means “place where branches have been cut for a garden.”

Chitemene, a slash and burn technique once common in Zambia, involves cutting down standing trees in the Miombo woodlands, stacking the logs, and then burning them to create a thick layer of ash believed to enhance soil fertility. The ashen fields are initially cultivated with pearl millet and followed by crops like cassava. As years progressed, this method has been associated with adverse environmental impacts disrupting the ecosystem balance due to increasingly shortened fallow and recovery periods. However, with the ever-changing climate, Bwalya and other farmers recognize the need for sustainable practices that require less labor.

Alternatives to the traditional methods

Since childhood, Maureen Bwalya, a mother of seven from Musa Camp in the Kasama District of northern Zambia, has dedicated her life to cassava farming. Thriving under very low fertility and acidic soils, cassava has offered a lifeline amid the challenges of rural agriculture. When the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project was introduced in the northern province, where cassava is a strategic crop, Bwalya saw a valuable opportunity for change to cultivate better practices that not only improve cassava yields but also replenish soil fertility in her fields.

“When I started these trials, it was a tough transition,” said Bwalya, reflecting on her journey. “Shifting from ridge planting to flat land cultivation posed its challenges as this practice was new to me. But with time, I have learned the advantages of intercropping: increased yields, less labor, and enhanced productivity, all of which enrich my farming practices.”

Implemented over the last five years by CIMMYT, in collaboration with FAO and the Ministry of Agriculture, SIFAZ aims to advance the intensification of farming practices and catalyze widespread adoption among farmers in Zambia. In the Musa camp, key partners took on the challenge of advancing better farming techniques with cassava. Their collective objective was clear: to identify methods that minimized labor intensity while maximizing yields. Through rigorous trials, including comparing flat land planting against traditional ridge systems and experimenting with intercropping cassava with common beans and groundnuts, promising results have been seen.

The outcomes yielded thus far have been nothing short of inspiring across farmers. It has become clear to farmers and researchers that cassava planted on flat land, particularly within a Conservation Agriculture (CA) framework, was not only feasible in high rainfall areas but also yielded significantly higher returns. Despite observing fewer root structures, the roots themselves proved to be robust and weighty, ultimately translating to increased productivity for smallholder farmers. Furthermore, farmers have confirmed that cassava from the CA plots tastes better than the one from the ridged portions.

“As a cassava trial implementer,” Bwalya said, “I undertook various trials exploring intercropping cassava with beans and groundnuts, across both flat and ridge systems.”

Thriving and innovating

Her six-hectare plot has become a hub of experimentation, with 0.3 hectares dedicated to the ongoing trials. Encouraged by the successes and promising yields witnessed on flat land, Maureen extended these sustainable practices to the remaining expanse, intercropping maize with cassava. Her results have been noticed, drawing the interest of over fifty neighboring farmers, inspired by her flourishing plot.

As the harvesting season approaches, Bwalya faces no shortage of opportunities to market her produce. From cassava cuttings to nutrient-rich leaves and tubers, she never runs short of eager buyers in local markets, ensuring a steady income for her family.

Navigating through the different trials across the Kasama district, pockets of adoption in some farmers’ fields are noticeable. Through collaborative partnerships and community engagement, SIFAZ strives to empower farmers with the knowledge and tools stemming from the trials to become more food secure in the face of evolving climatic challenges.

A tale of two worlds: contrasting realities in southern and northern Zambia during El Niño

From the densely lush landscape of Zambia’s northern province to the arid terrain of the south, a stark reality unfolds, intensified by El Niño. Zambia’s agriculture faces contrasting realities yet potential lies in adaptive strategies, a diversified crop basket, and collaborative initiatives which prioritize farmers. Despite persistent challenges with climate variability and uneven resource distribution, the country navigates unpredictable weather patterns, emphasizing the intricate interplay between environmental factors and adaptation strategies.

Unpacking El Niño’s impact in Zambia

El Niño presents a common challenge to both southern and northern Zambia, albeit with varying degrees of intensity and duration. The 2022/2023 season had above normal rainfall amounts, with extreme weather events, from episodes of flash floods and flooding to prolonged dry spells, especially over areas in the south. In the 2023/2024 season, the southern region has already experienced irregular weather patterns, including prolonged droughts and extreme temperatures, leading to water scarcity, crop failures, and significant agricultural losses. Although the growing season is nearing its end, the region has only received less than one-third of the annual average rainfall (just about 250 mm). Dry spells of more than 30 days have been experienced and, in most cases, coincide with the critical growth stages of flowering and grain-filling. A glance at farmers’ fields paints a gloomy picture of the anticipated yield, but all hope is not lost.

In contrast, the northern province stands out receiving above-average rainfalls beyond 2,000 mm, providing a different set of challenges for crop production. In this region, incidences of waterlogging are prominent although the effects are not as detrimental as the drought in the southern province. In general, crops in the northern province promise a considerable harvest as compared to the ones in the southern province.

Maize stover and its competing use

The scarcity of resources in southern Zambia extends beyond water availability, with the competition for maize stover, a valuable byproduct used for animal feed which can also be retained on the soil surface for fertility improvement and soil moisture conservation. With limited access to alternative fodder sources, farmers face challenges in meeting the nutritional needs of their livestock while maintaining soil fertility and conserving moisture. The struggle to balance the competing demands for maize stover underscores the complex dynamics of resource management in the region. This is further worsened by the low maize stover yield expected due to the dry conditions.

Implementing fodder trials, which include cultivating fodder crops like mucuna and lablab, intercropped or rotated with maize, offers a lifeline to farmers. While maize crops may wilt under the stress of El Niño-induced droughts, leguminous crops such as mucuna, lablab, cowpea, and groundnuts exhibit resilience, thriving in adverse conditions and providing a crucial source of food, feed, soil cover, and income for farmers. The ability of legumes to withstand environmental stressors highlights the importance of crop diversification in building resilience to climate change and ensuring food security in vulnerable regions.

Conversely, in northern Zambia, the abundance of agricultural resources allows for a more sustainable utilization of maize stover. Farmers have greater access to fodder alternatives and can implement integrated farming practices to optimize the use of crop residues. This enables them to mitigate the adverse effects of soil degradation and enhance livestock productivity, contributing to the resilience of their agricultural systems.

Use of more climate-smart crops

In southern Zambia, maize stands as the main crop, often supplemented with the integration of some leguminous crops integrated to some extent, to diversify the agricultural landscape. However, the relentless and longevity grip of El Niño has taken a negative toll on maize production, despite efforts to cultivate drought-tolerant varieties. As the dry spell persists, maize plants at the critical tasseling and silking stage face an uphill battle, as the dry and hot air has adversely impacted pollen and silk development.

The dissimilarity with the northern province, where cassava thrives from abundant water, is striking. This resilient crop, known for its drought tolerance, presents a promising alternative for farmers in the southern province grappling with erratic rainfall patterns. As climate change continues to challenge traditional agricultural practices, exploring resilient crops like cassava may offer a lifeline for communities striving to adapt and thrive amidst adversity.

In response to these radically different realities, the Sustainable Intensification of Farming Systems (SIFAZ) project, a collaborative effort of CIMMYT with FAO, the Ministry of Agriculture in Zambia, and the CGIAR Initiative on Diversification in East and Southern Africa, also known as Ukama Ustawi, have jointly promoted sustainable intensification practices to enhance the resilience of smallholder farmers.

The SIFAZ project is designed around the idea that strip crops and intercrops can add nutritional and economic value to Conservation Agriculture (CA) systems for smallholder farmers in Zambia. While traditional yield metrics provide some insight across the several intercropping treatments being tested on-farm, the true benefits of these cropping systems extend beyond mere output. SIFAZ recognizes the diversification synergy, emphasizing that “two crops are better than one.”

However, the outcomes of the SIFAZ project and the CGIAR Initiative on Diversification in East and Southern Africa have varied over the years between the two regions, reflecting the discrepancy in their agricultural landscapes.

Notably, regional differences in the adoption and success of these cropping systems have become apparent. In the northern province, crop-centric approaches prevail, leading to a higher concentration of successful crop farmers. Meanwhile, in the southern province, mixed systems that incorporate mixed crop-livestock systems achieve desirable effects. These findings highlight the importance of tailoring agricultural interventions to suit the specific needs and conditions of diverse farming communities.

Navigating the complex challenges of climate change requires a multifaceted approach that acknowledges the unique realities of different regions. By embracing adaptive strategies, harnessing indigenous knowledge, and fostering collaborative partnerships, Zambia can forge a path towards a more resilient and sustainable agricultural future, where farmers thrive despite the uncertainties of a changing climate.
