Building global capacity to combat wheat blast

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 ïŹrst 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

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

CA in action at the farmer level. (Photo: Christian Thierfelder/CIMMYT)

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

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

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

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.

To foster collaboration and knowledge sharing, CIMMYT hosted a 2-day workshop in September 2023 in Lusaka, Zambia, on appropriate mechanization for smallholder farmers in the Global South. This event was part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub funded by the United States Agency for International Development (USAID).

Recognizing that equitable access to finance and credit are key enablers for mechanization, this platform strived to understand smallholder farmer needs and the identification of key financing models to facilitate widespread adoption.

With over 40 participants ranging from government representatives, development partners, and stakeholders from organizations such as USAID, the Food and Agriculture Organization (FAO), the International Institute of Tropical Agriculture (IITA), the International Fertilizer Development Center (IFDC), and Hello Tractor, this regional event provided an opportunity for robust discussions and to align the course of action.

Unpacking mechanization in the Global South

Appropriate-scale mechanization is essential and a top policy priority to transform African agriculture. Evidence shows that nearly 70% of operations in sub-Saharan Africa are done manually. However, human labor is limited and is increasingly scarce and costly given the unfolding transformation of rural spaces in most places, necessitating agricultural mechanization. The cornerstone of this shift lies in integrating small, affordable machines tailored to the operations and needs of smallholder farmers, which must be accessible through market-based financial and business models.

A top policy priority in Zambia

The Permanent Secretary, Technical Services of the Zambian Ministry of Agriculture, Green Mbozi, officially opened the meeting. He lauded the meeting as timely and commendable as agriculture mechanization is a top policy priority for Zambia.

“The government has embarked on a process to formulate a national mechanization strategy, which will serve as a blueprint on how to sustainably promote agricultural machinery and equipment across the value chains. The insights from this workshop would be helpful in feeding into the formulation of the strategy and help in identifying entry points to support sustainable agriculture mechanization,” said Mbozi.

Accelerating change through inclusive dialogues

The dialogue played a crucial role in bolstering support for sustainable agriculture mechanization while tackling challenges hindering active adoption. Mbozi highlighted the imminent launch of an agricultural mechanization strategy developed with technical support from FAO and CIMMYT through the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project.

The mechanization strategy champions sustainable and efficient mechanization practices, strengthens the private sector’s role in mechanization, and provides training and financial support to small-scale farmers, women, and youth. Proposed initiatives include regional centers of excellence, a national mechanization association, and the use of information and communication technologies to promote mechanization.

“It is important to develop the right bundle of mechanization services that meet the needs of farmers and are profitable for mechanization service providers,” said Director of Sustainable Agrifood Systems (SAS) at CIMMYT, Sieg Snapp. “Finding the right financing is needed to support multiple bundles of mechanization services, which provide profits throughout the year.”

Additionally, the SIFAZ project promotes local manufacturing, supporting quality assurance, conducting demand studies, and establishing an agricultural mechanization data bank to catalyze transformative progress.

Key insights from USAID and FAO

David Howlett, the Feed the Future coordinator at the USAID Mission in Zambia, shared with participants that, “USAID is working to address the effects of climate change through mechanization and other adaptation strategies.” Aligning with the central focus of the meeting, he further reiterated that mechanization will be key to building resilience by improving agricultural systems.

Offering insights drawn from country-level experiences on scale mechanization for smallholder farmers, Joseph Mpagalile from FAO said, “FAO has been helping countries develop national agricultural mechanization strategies, with 12 countries in Africa already revising or preparing new strategies for sustainable agricultural mechanization.”

Private sector engagement: lessons from Hello Tractor

Operating across 13 African countries, Hello Tractor has been leveraging digitalization to scale mechanization in Africa since its inception. Hello Tractor facilitates services to over 500,000 smallholder farmers through 3,000+ tractors and combine harvesters, while providing remote tracking of assets and preventing fraud and machine misuse for machinery owners. At the heart of the company are booking agents who connect farmers to solutions to increase productivity and income.

Call to action

As the discussions ended, key outcomes distilled highlighted a pressing need to sensitize farmers on the merits of mechanization and facilitating access through tailored financial resources. Special attention was also directed towards empowering women and youth through implementation of de-risking mechanisms and strategic marketing linkages.

Recognizing the critical absence of data, a compelling call for a funding pool to collect essential information in the ESA region became clear. In addition, it was emphasized that appropriate-scale mechanization should be driven by sustainable business and financing models. The journey towards mechanization is a collective effort, blending policy initiatives, private sector engagement, and research-driven strategies.

Reaching farmers in Zambia

It is challenging to disseminate information across far-flung areas of rural Zambia as extension officers must travel vast distances to reach farmers. The Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub, managed by CIMMYT and funded by the United States Agency for International Development (USAID) helps alleviate these issues by engaging with existing mobile phone networks to reach farmers with agronomic information, weather data, and soil information.

To introduce farmers to these specific tools: Atubandike and VIAMO, AID-I conducted a community sensitization and engagement exercise in Zambia. Atubandike emphasizes farmer learning and feedback using mobile phones for disseminating knowledge about the new generation of drought-tolerant varieties, sustainable intensification practices, and collecting farmer feedback to enable demand-driven delivery under AID-I. VIAMO, accessible via a basic mobile phone, provides agronomic information for every farmer in a specific area. The platform comes in different languages and farmers access information on various crops such as maize, beans, and groundnuts in their native language, provide feedback on information content, and connect with other farmers.

In Choma District, Morgan Katema, who provides extension services to farmers, explained that going digital is one way of reaching farmers through technology to ensure that all farmers have access to extension services. “In this case, lessons will be available through mobile phones and farmers will ask agriculture-related questions and get a response. This is a good initiative because farmers can access information on the spot instead of waiting for an extension officer to reach them, and information can be accessed after working hours, and the VIAMO initiative will help us overcome the challenge of long distances between farmers as we will no longer need to travel long distances,” Katema said.

Judith Simuliye, a farmer who grows maize and groundnuts, said, “I was told about this meeting by the camp officer, and I am happy to learn about this project. I have learned how to manage my crop by using the right seed varieties and how to space the crops.”

During the meeting, two community facilitators were selected through a voting process, after farmers nominated community members who are literate, trustworthy, energetic, and able to use a smart phone. Facilitators register farmers on the VIAMO platform, assist them in accessing the information they require, and support them in their learning journey.

Namasumo Rithay, a farmer in the village of Kalalasa, said, “Mobile phone access to extension services has come at the right time. We have faced a lot of challenges with the poor rain patterns and pests. Through this meeting organized by AID-I, we have learned how we can obtain information to mitigate these challenges through our mobile phones.”

An additional community meeting was held in the village of Namuswa and was attended by 150 farmers. AID-I and Atubandike Research Associate, Brian Mpande, informed farmers that AID-I, with the assistance from VIAMO, will help them overcome the challenges of climate change by delivering timely and useful information via their phones. 

Market segmentation and Target Product Profiles (TPPs): developing and delivering impactful products for farming communities

With the ever-changing climate conditions, including the unpredictable El Niño, and dynamic changes in government policies, understanding farmers’ preferences and market segmentation has become crucial for implementing impactful breeding programs. Market segmentation is a strategic process which divides a market into distinct group of consumers with similar needs, preferences, and behaviors. This allows organizations to tailor their products and services to specific customer segments, thus ensuring maximum value and impact.

In today’s fast-paced and evolving agricultural landscape, market segmentation plays a vital role in helping organizations navigate the complexities of a dynamic market. CIMMYT’s maize breeding program has a successful track record in developing and delivering improved varieties that are climate-resilient, high-yielding and suited to the rainfed tropical conditions in Africa. To further strengthen the impact, it is important to have a clear understanding of the evolving needs of farmers in different agroecological regions and the emerging market scenario so that breeding processes can be tailored based on market needs and client requirements.

Questions arise on how to refine the breeding programs relative to country-specific market segments, what efforts are underway to target these markets, and how do these markets transition. Recognizing the importance of market segmentation in refining breeding programs at the country and regional levels, CIMMYT hosted two workshops on maize market intelligence in Kenya and Zimbabwe, under the CGIAR Market Intelligence Initiative for eastern and southern Africa.

“Market intelligence in breeding programs is critical to understand the evolving needs of key stakeholders, including farmers, consumers, and the seed industry. It helps continuously improve the breeding pipelines to develop and deliver impactful products in targeted market segments. The workshops brought together relevant experts from the national programs and seed companies for focused discussions to develop a harmonized breeding strategy. This would help to address the needs of smallholder maize farmers in eastern and southern Africa,” said Director of CIMMYT’s Global Maize program and One CGIAR Global Maize Breeding Lead, B.M. Prasanna.

The workshops constituted a strategic continuation of the Product Design Team (PDT) meetings under CGIAR Market Intelligence, with a focus on the refinement of gender-intentional target product profile design. Guided by the expertise of CIMMYT’s Global Maize program, Market Intelligence, and ABI-Maize Transform teams, the sessions saw active participation from key stakeholders including lead breeders, seed systems experts, and market specialists from the National Agricultural Research and Extension Systems (NARES), alongside collaborative engagement with seed company partners. The workshops underscored the commitment to incorporate diverse perspectives, aligning with the evolving maize market landscape in eastern and southern Africa.

“The workshop provided critical insights on opportunities to improve market penetration of improved maize varieties. There is a need to strike a balance between the needs of the farmers, seed industry, and consumers in variety development; actively involve farmers and consumers in variety selection and understanding their preferences; and focus on emerging needs of the market such as yellow maize for feed and food,” said James Karanja, maize breeding lead at the Kenya Agriculture & Livestock Research Organization, Kenya.

Insights from both workshops underscored the importance of providing breeders with pertinent information and comprehensive training. The discussions illustrated the necessity for breeders to define their objectives with a 360-degree outlook, aligning breeding programs with market segments and interfacing with CIMMYT’s regional vision.

“The market intelligence workshop is an excellent initiative for the breeding programs. It shows how traits can be identified and prioritized, based on farmers’ requirements. The maize value chain is broad, and the synergy between the developer of the product (breeder), the producer (farmer), and the consumer needs to be effective. Hence, streamlining of the market segments and eventually the target product profiles is key in ensuring that the breeders develop improved products/varieties with relevant traits that address the needs of farmers, consumers, and the seed industry,” said Lubasi Sinyinda, breeder from the Zambia Agricultural Research Institute, Zambia.

Another participant, Lucia Ndlala, a maize breeder at the Agricultural Research Council, South Africa, echoed similar enthusiasm. “The workshop was exceptionally informative, providing valuable insights into target product profiles and market segments. This knowledge will undoubtedly prove instrumental in shaping future breeding strategies,” she said.

When applied through a breeding lens, market segmentation is a vital tool in refining breeding programs at both country and regional levels, enabling breeders to better understand and address the diverse needs of the farmers, and ensuring that the improved varieties are tailored to market segments.

Soybean rust threatens soybean production in Malawi and Zambia

Soybeans are a significant source of oil and protein, and soybean demand has been increasing over the last decade in Malawi and Zambia. Soybean contributes to human nutrition, is used in producing animal feed, and fetches a higher price per unit than maize, thus serving as a cash crop for smallholder farmers. These are among the main factors contributing to the growing adoption of soybean among smallholder producers. In addition, soybean is a vital soil-fertility improvement crop used in crop rotations because of its ability to fix atmospheric nitrogen. To a large extent, soybean demand outweighs supply, with the deficit covered by imports.

Soybean production in sub-Saharan Africa is expected to grow by over 2% per annum to meet the increasing demand. However, as production increases, significant challenges caused by diseases, pests, declining soil fertility, and other abiotic factors remain. According to official government statistics, Zambia produces about 450,000 tonnes of soybean per annum, with an estimated annual growth of 14%. According to FAOSTAT, this makes Zambia the second largest soybean producer in the southern African region. Although soybean was traditionally grown by large commercial farmers in Zambia, smallholders now account for over 60% of the total annual soybean production.

Production trends show that smallholder soybean production increased rapidly in the 2015–2016 season, a period that coincided with increased demand from local processing facilities. As smallholder production continued to increase, in 2020, total output by smallholder farmers outpaced that of large-scale farmers for the first time and has remained dominant over the last two seasons (Fig 1). However, soybean yields among smallholder farmers have remained low at around 1 MT/HA.

Soybean production in the region is threatened by soybean rust caused by the fungus Phakopsora pachyrhizi. The rust became prevalent in Africa in 1996; it was first confirmed in Uganda on experimental plots and subsequently on farmers’ fields throughout the country. Monitoring efforts in the U.S. have saved the soybean industry millions of dollars in fungicide costs due to the availability of accurate disease forecasting based on pathogen surveillance and environmental data.

Soybean rust disease is spread rapidly and easily by wind, and most available varieties grown by farmers are susceptible. The above-normal rainfall during the 2022–2023 season was conducive to the spread of the fungus. A recent survey of over 1,000 farm households shows that 55% and 39% of farmers in Zambia and Malawi, respectively, were affected by soybean rust during the 2022–2023 season. The lack of rust-tolerant varieties makes production expensive for smallholder farmers who cannot afford to purchase fungicides to control the pathogens. It is estimated that soybean rust can cause large yield losses of up to 90%, depending on crop stage and disease severity. Symptoms due to soybean rust infection may be observed at any developmental stage of the plant, but losses are mostly associated with infection from the flowering stage to the pod-filling stage.

Mitigation measures using resistant or tolerant varieties have been challenging because the fungus mutates very rapidly, creating genetic variability. Although a variety of fungicides effective against soybean rust are available, the use of such fungicides is limited due to the high cost of the product and its application, as well as to environmental concerns. Due to this restricted use of fungicide, an early monitoring system for detecting rust threats for steering fungicide might only be relevant for large-scale producers in eastern and southern Africa. With the massive increase in the area under soybean production, soybean rust is an important disease that cannot be ignored. Host-plant resistance provides a cheaper, more environmentally friendly, and much more sustainable approach for managing soybean rust in smallholder agriculture that characterizes the agricultural landscape of eastern and southern Africa.

To advance the use of rust-tolerant varieties, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is presently concluding surveys to assess farmers’ demand and willingness to pay for rust-tolerant varieties in Malawi and Zambia. The results from this assessment will be valuable to seed companies and last-mile delivery partners to gain a better understanding of what farmers need and to better serve the farmers.  This coming season AID-I will include rust tolerant varieties in the mega-demonstrations to create awareness about new varieties that show some tolerance to rust.

Enhancing partnerships for agricultural development

Implementing partners of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) project, or MasAgro Africa, converged in Arusha, Tanzania, for the project’s first annual review and planning meeting. The event, which brought together 58 participants from 28 allied organizations coordinating and implementing activities as part of the flagship USAID-funded initiative, provided an opportunity to review progress towards targets set at the project launch in September 2022. During the event, partners also took time to collaboratively plan for stronger implementation in the project’s second year, while discussing challenges faced in the previous year and coming up with practical solutions for these. Similar planning meetings took place in Malawi and Zambia during the same month.

Speaking during the meeting’s opening session, USAID Tanzania Mission Feed the Future Coordinator Melanie Edwards expressed excitement about the achievements of in-country partners in the past year. “The Tanzania component of the project was performing very well,” she said, “and it was exciting to see the proposals coming, meaning that the number of partners was expanding.” Edwards noted that there is still a lot more to be done by the AID-I project and a call for new partner proposals was going to be issued soon to augment ongoing work. She also emphasized the importance of expanding the number of partners and was eager to see planned activities for the second year of the project.

Speaking on behalf of the Government of Tanzania—a key partner in the AID-I initiative—Abel Mtembenji outlined the government’s priorities: increasing productivity, creating decent jobs, enhancing extension services, improving resilience for food security, and expanding market and credit access. Mtembenji was pleased that AID-I interventions aligned with these and encouraged stakeholders to coordinate their efforts with the Tanzanian government to enhance the sustainability of project activities. He further encouraged stakeholders to notify the government of their initiatives to foster collaboration during implementation. Mtembenji recognized the support from USAID, through CIMMYT and thanked all partners for their participation and contribution to agricultural development in Tanzania.

Showcasing early successes

The AID-I initiative provides targeted assistance to up to three million African smallholder farmers by improving soil health and fertilizer management; strengthening local seed systems; connecting to financial products and services; and delivering extension and advisory services. An update presentation made by SAS Program Manager Grace Mwai revealed that through its 42 partners across Malawi, Tanzania, and Zambia, AID-I had in the past 12 months set up 125 mega-demonstrations for the 2022-2023 season. Forty-two of these were managed by farmer groups themselves, with 60% managed by women.

Across all three project countries, AID-I also reached approximately 5.3 million farmers with various agronomic advisory messages through radio and television, 160,000 listeners through interactive voice response (IVR) messages. Over 9,000 farmers were linked to inputs and outputs markets, of which 40% were women. Mwai added that the project had also conducted 5,143 seed company demonstrations—of which 2,400 took place in Tanzania—and had harvested and processed 13,000 metric tons of certified maize and legume seed, which was expected to directly benefit around one million smallholder farmers across the hub.

To highlight achievements from the first project year, partners showcased their products through posters and display items like seed packets during a structured session based on the World Café method. This activity allowed participants to interact and ask questions about various innovations being scaled under AID-I. More than ten partners displayed their products, and all participants at the meeting were given 15 minutes to visit other tables and share how many tons of seed they had produced and how many farmers they could reach during the season.

On the second day of the meeting, partners organized themselves into three small groups based on the three AID-I pillars—Seed Systems, Agriculture Advisories, and Market Linkages—to discuss forthcoming activities and what they hoped to do better in the coming season. The meeting concluded with discussions on issues including financial reporting, establishing and nurturing collaborations, and leveraging technology for improved project outcomes. During his closing remarks, Legume and Seed Systems Specialist under AID-I, Peter Setimela, emphasized the importance of timely proposal submission for the second year.

Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of southern Africa (ACASA)

Conservation agriculture (CA) has increasingly been promoted in southern Africa to address low agricultural productivity, food insecurity, and land degradation. Despite significant experimental evidence on the agronomic and economic benefits and the large scaling-up investments by donors and national governments, the adoption rates of CA practices among smallholder farmers are low and slow.

With funding from the Norwegian Agency for Development Cooperation (NORAD) and implemented by the International Institute of Tropical Agriculture (IITA) and CIMMYT, ACASA strives to understand “why previous efforts and investments to scale CA technologies and practices in southern Africa have not led to widespread adoption.” It is a three-year project implemented in Malawi, Zambia, and Zimbabwe, where CA is part of national policy.

Since 2021, the project has undertaken extensive surveys aimed to understand incentives, drivers, and barriers of CA adoption across the three countries (Malawi, Zambia, and Zimbabwe) typifying much of the southern Africa smallholder systems. The aim of the project is to consolidate the lessons learned so far and provide a pathway to scaling and foster the next generation of social, crop, agronomic and climate research; to mainstream CA enabled by fundamental paradigm shifts in farming practices, markets, and social institutions for sustainable intensification of smallholder farming systems of southern Africa.

Project objectives include –

  • Understanding the contexts of smallholder farmer in southern Africa to identify the drivers and barriers preventing adoption of CA practices, including biophysical, socio-economic, institutional and policy constraints
  • Identifying labor-efficient mechanization options for smallholder farmers
  • Identifying opportunities and tools for better targeting of appropriate CA practices and options across heterogenous agroecologies and farm types, and
  • Identifying approaches and strategies for inclusive scaling of CA practices (policy, institutional and value chain entry points and pathways to promote and scale CA)

 

Afriseed: How improved legume seed can help transform Zambia’s agrifood systems

In Zambia, smallholder farmers obtain their seed from a variety of sources. Over 75 percent of farmers in Zambia have adopted certified maize seed and about 30 percent in southern Africa, overall. The private sector has been instrumental in creating demand for certified and timely delivery of seed to remote areas, and the Government of Zambia’s Farmer Input Support Programme (FISP) has largely contributed to better accessibility to certified seed for farmers. In 2022–2023, of the three million registered smallholder farmers in Zambia, more than one million accessed certified seed through FISP.

Afriseed is a seed company in Zambia that has been gaining ground in local seed markets. It has emerged as a catalyst for helping smallholder farmers transition to new, high-yielding legume varieties. Afriseed provides solutions to help smallholders increase their agricultural productivity with improved seed varieties of cereals and legumes and assist them with technology transfer. The company aims to increase the food security and incomes of Zambia’s smallholder farming community, which accounts for 90 percent of agricultural output in the country. During the 2022–2023 farming season, a critical turning point was reached when Afriseed became a partner in the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, a two-year project under CIMMYT, with the aim of scaling-up production of certified seed varieties of soybean and common bean.

Under the partnership, Afriseed promotes the cultivation of improved legume seed through a smallholder farmer seed multiplication approach. By engaging with practicing smallholder farmers and signing grower contracts, basic seeds are multiplied into certified seed for soybean and common bean. Certified seed is a known variety produced under strict seed certification standards to support varietal purity. In collaboration with the Seed Control and Certification Institute (SCCI), the country’s national seed authority, contracted farmers received training on climate-smart agricultural techniques and seed production guidelines. Through extension services to seed growers, smallholder farmers can adhere to the seed production guidelines set out in the National Seed Act to ensure the quality of certified seed produced.

Afriseed has invested more than USD 335,000 toward supporting the production, aggregation, and processing of 317 t of certified climate-smart legume seeds—265 metric tonnes (MT) for soybean and 52 MT for common bean. Data have shown that the seeds were aggregated from 313 smallholder seed growers, 40 percent of whom were women, in Zambia’s Eastern Muchinga, Copperbelt and the Northern provinces. Seed aggregation improves access to quality seed varieties, increases crop yields and incomes, enhances integration into value chains, and creates market links for smallholder farmers.

Notable progress has been made with the contracted farmers, who have applied improved crop management practices and technologies on more than 600 ha of land to produce the seed. With this encouraging progress, Afriseed intends to scale up its last-mile seed distribution strategy to reach and directly help an estimated 35,000 underserved rural smallholder farming households with improved legume seeds in the 2023–2024 cropping season.

AID-I is one of the ways in which Feed the Future, the U.S. Government’s global food security and hunger initiative led by USAID, is taking immediate action to help cushion the blow of high fuel and fertilizer prices on farmers. One of the project’s initial actions is to strengthen local seed systems so that agribusinesses can reach smallholder farmers with a diversity of improved seeds varieties, including climate-resilient and more nutritious varieties for maize and legumes.

Strengthening seed systems with Zamseed

Maize is a vital crop in Zambia and Tanzania, both for farmers’ economic livelihoods and for delivering nutrients and sustenance to a large group of people. But maize is threatened by climate change, like more severe droughts, and from pests like fall army worm (FAW), which can completely devastate farmers’ fields.

Against this backdrop of looming threats, CIMMYT, as part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is partnering with the Zambia Seed Company Limited (Zamseed) to distribute seeds that are drought tolerant and resistant to the ravages of FAW. And because maize is a staple of many people’s diets, CIMMYT and Zamseed are also developing and distributing maize varieties enhanced with vitamin A.

To uphold maize variety integrity, CIMMYT and Zamseed are engaged in the capacity building of quality assurance and quality control for local stakeholders.

CIMMYT’s engagement with Zamseed involves efforts to popularize high yielding, drought-tolerant, and vitamin enhanced maize varieties in Zambia and Tanzania. Some of these efforts include demonstrations of the new varieties, field days held at different stages of maize development, and deliberate engagement of women throughout the entire seed selection, planting and harvesting effort.

“Our partnership with Zamseed started in October 2022,” said Ir Essegbemon Akpo, a CIMMYT maize seed systems specialist. “It has been a fruitful collaboration, delivering significant outputs to thousands of farmers in Zambia and Tanzania.”

To date, Zamseed has held 300 and 500 demonstrations in Tanzania and Zambia, respectively. The company has held many field days at the demonstration sites to showcase drought tolerant and vitamin A enhanced maize to hundreds of small-scale farmers.

“We have witnessed many farmers who visited the demonstration activities who are excited to see the new high yielding and drought tolerant varieties,” said Amsal Tarekegne of Zamseed.

Seeded by funds from the AID-I project, Zamseed is producing 60kg of Early Generation Seed (EGS) of parents of a FAW-tolerant hybrid maize variety. The company plans to produce 200kg of this hybrid for commercialization and launch in 2024.

To ensure that seeds delivered to farmers are of the highest quality, CIMMYT is working with Zamseed to develop quality assurance and control frameworks, involving genotyping of selected seeds at various times during the seed multiplication and distribution process.

Zamseed has been servicing the requirements of farmers in the sub-Sahara region since 1980, focusing on products that will enhance the profitability of the small-scale farmer and ensure household food security.
