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 2015â2016 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 2022â2023 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 2022â2023 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 farmersâ 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. Â 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.
The livestock sub-sector is one of the most important arms of the agricultural sector, contributing to the livelihoods of 70% of Zimbabwe’s rural population. Sustainable livestock production depends on the maintenance of healthy and productive animals which requires paying particular attention to the problems of both endemic and introduced animal diseases and zoonotic. Climate relevant livestock production practices such as fodder management and conservation, water harvesting, and manure management have been identified as solutions to increasing livestock productivity.
The Livestock Production Systems in Zimbabwe (LIPS-Zim) project, funded by the European Union (EU) focuses on increasing agricultural productivity in Zimbabwe’s semi-arid, agro-ecological regions IV and V. Led by the International Livestock Research Institute (ILRI) and in partnership with CIMMYT, the French Agricultural Research Center for International Development (Cirad) and the University of Zimbabwe (UZ), LIPS-Zim is working in 10 districts of Zimbabwe, i.e. Matabeleland South Province (Beitbridge and Gwanda districts), the parched Matabeleland North Province (Binga, Hwange and Nkayi districts), Midlands (Gokwe North district), Masvingo (Chiredzi and Zaka districts), Manicaland (Buhera district) and Mashonaland East (Mutoko district). LIPS-Zim is conducting research that seeks to increase livestock feed productivity and well as reducing diseases and mortality of livestock.
Main objectives
Core to the project is to increase the adoption of climate-relevant innovations (e.g feeding) in livestock-based production systems and improve the surveillance and control of livestock diseases. CIMMYTâs main thrust in this project is based on the recognition that at least 50% of the arable land area in semi-arid region IV and V of Zimbabwe is still put to maize despite extension recommendations for farmers to grow the more resilient small grains in those regions. Given the above, and to address their food and feed needs, farmers in those regions need drought-tolerant and nutritious maize varieties that are resilient in those dry environments. CIMMYTâs work is thus focusing on testing the feed value of these nutritious and drought tolerant maize varieties when intercropped with various legumes such as mucuna, cowpea, lab-lab and pigeonpea. CIMMYT is also testing the later, along with climate smart production techniques such as conservation agriculture and water harvesting practices.
Social Network Analysis (SNA) provides CIMMYT with strategic insights by mapping collaborations and communication within agricultural research networks. It highlights the importance of strong ties with research partners and the potential of non-CGIAR collaborations to extend CIMMYT’s impact on global agriculture, emphasizing network-driven strategies for innovation and food security enhancement.

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 projectâs 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 meetingâs opening session, USAID Tanzania Mission Feed the Future Coordinator Melanie Edwards expressed excitement about the achievements of in-country partners in the past year. âThe Tanzania component of the project was performing very well,â she said, âand it was exciting to see the proposals coming, meaning that the number of partners was expanding.â 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 Tanzaniaâa key partner in the AID-I initiativeâAbel 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 demonstrationsâof which 2,400 took place in Tanzaniaâand 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 pillarsâSeed Systems, Agriculture Advisories, and Market Linkagesâto 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.
Rapid urbanization, globalization, economic development, technological advancement, and changing agriculture production systems in South Asia are transforming food systems and the food environment.
India and Bangladesh, particularly, have seen a significant transformation since the advent of the Green Revolution as each became able to feed their population without having to import major crops.
However, that policy focus on food self-sufficiency and yield intensification has incurred significant health, environmental and fiscal costs, including a precipitous drop in crop diversification*.
This loss of crop diversification threatens economic and social development and environmental stability while weakening the crucial link between agriculture and community health, particularly in undernourished rural areas. To ensure sustainable food production and nutritional security, it is imperative to manage and conserve crop diversification.
To address these issues and ensure sustainable food production, there is an urgent need to transition from intensive to sustainable farming practices.
CIMMYT exploring crop diversification pathways
CIMMYTâs ongoing projects in South Asia, including the Transforming Agrifood Systems in South Asia (TAFSSA) and Transforming Smallholder Food Systems in the Eastern Gangetic Plains (RUPANTAR) are conducting extensive on-site and on-farm trials, including socioeconomic dimensions of farmers to promote crop diversification.
âTo effectively address the challenges of crop diversification, it is essential to integrate on-farm trials and participatory action research, involving farmers in the experimentation and adaptation process tailored to their unique regional needs,â said Ravi Nandi, innovation systems scientist at CIMMYT in Bangladesh. âThis hands-on involvement provides valuable data to guide policymaking, ensuring relevance and applicability.â
In addition, TAFSSA and RUPANTAR are engaging in participatory action research to uncover the most viable options for crop and livelihood diversification, understand the socioeconomic factors impacting farmers, and identify the potential opportunities and challenges associated with the crop and livelihood diversification efforts among the farmers.
Researchers completed two comprehensive surveys, engaging with 2,500 farmers across the Eastern Gangetic Plains (EGP) of India, Nepal and Bangladesh, yielding valuable data that will inform future strategies for crop diversification in the region.
Ongoing investigations into the political economy of policies for crop diversification in Bangladesh generate novel insights, further contributing to the development of efficient crop diversification projects and sustainable agricultural policies.
The rise of crop diversification in practices and policy
In recent years, crop diversification has gained traction as a promising strategy to boost agricultural productivity, reduce risks (production, market, climate, and environmental), enhance nutritional outcomes, and promote sustainable agriculture.
Following the inaugural National Conference of Chief Secretaries in Dharamshala, India, led by the Prime Minister of India, state governments introduced numerous policies and schemes to support crop diversification. Some of these initiatives, highlighted in Figure 1, were backed by substantial budget allocations aimed at motivating farmers to diversify their crop production from the current intensive production system.
Similar initiatives have been started in Bangladesh, Nepal and other South Asian countries to promote crop diversification. These policies and schemes are important steps towards addressing inadequacies that intensive farming has created in agriculture and food systems.
While policies promoting crop diversification in South Asia are a positive step, their effectiveness is contingent on evidence-based decision-making. The complexities of implementing diversification strategies vary significantly depending on local contexts, particularly in countries like India, Nepal and Bangladesh, where most farmers operate on less than one hectare of land and face diverse weather conditions.
Smallholder farmers, at risk of losing economic stability from abandoning profitable monocrops, face additional challenges because of limited access to advanced technologies and fragmented markets, making the transition to diversified farming a precarious endeavor.
A shift towards comprehensive multi-criteria assessments, including qualitative methods and stakeholder interactions, is necessary for creating practical and locally relevant indicators. Supporting infrastructure, accessible extension services and market development, along with empowering farmers through education on agronomic practices and crop management, will play a crucial role in successfully implementing and reaping the benefits of crop diversification.
*Crop diversification is a process that makes a simplified cropping systems more diverse in time and space by adding additional crops.Â
In Central and West Asia and North Africa (CWANA), agri-food systems are under pressure from resource depletion, population growth, and food insecurity. CIMMYT’s work is vital, focusing on sustainable agricultural practices and innovative technology to enhance productivity and resilience. Research and development efforts are critical in addressing the environmental and socio-economic challenges of agriculture in this diverse and dynamic region.

As geographical neighbors, Bangladesh and India share many characteristics in terms of land, weather, and food production. Because of these similarities, the Feed the Future Cereal Systems Initiative for South Asia-Mechanization Extension Activity (CSISA-MEA) organized a series of exposure visits to India for Bangladeshi farmers and other agricultural stakeholders to establish market linkages, provide access to financial and technical advice.
The CSISA-MEA, funded by the United States Agency for International Development (USAID) works to increase the usage of agricultural machinery to benefit farmers by increasing their productivity and efficiency. The Activity works with several stakeholders, including agriculture-based light engineering (ABLE) enterprises, dealers, and machinery solution providers (MSPs).
Over the course of the activity, a significant lesson learned is that both groups, the hosting party and the visiting party, benefit from exposure visits.
CSISA-MEA organized two international exposure visits to India in July 2023. A total of 34 participants in two cohorts visited India, 18 workers from Faridpur and Coxâs Bazar, and 16 from Bogura and Jashore.
CSISA-MEA arranged the visits with the objective to familiarize Bangladesh ABLE enterprises with modern agri-machinery manufacturing and improve their working practices. The visits covered factories, ABLE workshops and foundries in Punjab, including Amargarh, Bamala, and Ludhiana, areas where Indiaâs agriculture mechanization is most notable, and incorporated public and private sector companies, and academia including LANDFORCE, M/S Dasmesh Mechanical Works, Panesar Agriculture Works Pvt. Ltd., Sokhi Manufacturing Ltd., the Borlaug Institute for South Asia, and National Agro Industry.
Learnings from the exposure visit
The exposure visits have emphasized the importance of systematic line production for machinery and spare parts manufacturing to ensure efficiency and consistency in output. Quality control has been highlighted as a non-negotiable aspect, and the significance of delivering reliable and high-quality products. Using natural light and ventilation systems showcased the potential for environmentally friendly production facilities.
The visits also highlighted how maintaining proper occupational health and safety measures ensures the well-being of the workforce along with a gender inclusive environment in the agri-machinery factories. The factories have a significant female workforce, an eye-opening sight for the ABLE owners of Bangladesh.
These exposure visits have helped equip ABLE owners with invaluable insights and strategies for success in their agricultural machinery businesses, including building connections among themselves, such as that between two ABLEs from Jashore, Bangladesh to facilitate the production and supply of the fodder chopperâdemonstrating the potential for cooperation to expand market reach.
Reflections from the visits
The trip to meet their Indian counterparts provided CSISAâMEA ABLE owners with invaluable insights and knowledge, with their unanimous feedback reflecting the profound impact of the visits, which they deemed truly eye-opening. Encouragingly, since their return, each ABLE enterprise has prepared action plans, taking proactive steps to implement the new techniques and business strategies they gained during their visit.
âI can’t express how thrilled I am to have unlocked the secrets behind the exceptional quality of Indian machines and spare parts. It’s not just a technical upgrade, it’s a commitment to quality products,â said Md. Ashraf Hosen, owner of M/S Ashraf Machinery & Akmol Engineering Workshop.
Another visitor, Md. Iqbal Hosen, proprietor of Titas Moulding & Engineering Works, said, âI found discovering new innovations very exciting, especially the core-making process, the mechanical mold-making process to reduce production costs, appropriate charge calculation techniques and induction furnaces. Iâm determined to apply these things in my foundry, to improve the quality of the products and reduce production costs.â
Sarkar Agro-Engineering & Multiple Works in Bangladesh has displayed a commitment to implementing the key takeaways of the exposure visit to India. The owners have ensured natural light and ventilation in their production facilities, creating a more conducive and eco-friendlier working environment for staff. They have also installed a customized lathe machine, painting every part of a machine before assembling it, and manufacturing mini tractors, all because of their exposure visit.
CSISAâMEA staff have also taken something from the trips, including feedback to include demonstrations of forging machines in future visits to further extend the workforceâs technical knowledge. There are plans to visit local spare parts markets during the next expedition to provide participants with a broader understanding of market dynamics, while visits to solar power and battery-operated machinery companies would provide an opportunity to witness sustainable technologies in action.
Ethiopia is the largest wheat producer in East Africa, with about 65% share of the total wheat production in sub-Saharan Africa. The area under wheat increased from about 1.5 million hectares in 2010 to 2.5 million hectares in 2023. More importantly, the productivity increased from 1.8 tons per hectare to about 3 tons per hectare in the same period, implying an increase of about 5% per annum in productivity (See Figure 1).
Several factors have contributed to this spectacular increase in productivity, including better farm practices implemented through clustering farmers land to reduce production costs, and introducing new, improved varieties which enable farmers to withstand challenges of crop diseases.
A DNA finger printing study found that about 87% of the wheat area in Ethiopia comprises of varieties developed by the International Maize and Wheat Improvement Center (CIMMYT). In 2023, the Ethiopian Institute of Agricultural Research (EIAR) released six new wheat varieties of CIMMYT origin aimed for the mid to highlands (> 1800 meters above sea level) and lowlands (< 1800 masl) of the country. âThese newly released varieties provide options for farmers to face devastating rust diseases and at the same time obtain higher productivity,â said wheat breeder Leonardo Crespo.
Gadisa Alemu, wheat breeder based in EIAR, Kulumsa, added that the CIMMYT varieties were tested in farmersâ fields prior to release. âThis allows participating farmers to have quicker access to seed of selected varieties,â he said.
Wheat breeders . The aim was to obtain additional insights into the activities of CIMMYTâs partners and co-design a strategy that allows early evaluation and access to CIMMYT germplasm by national partners in Ethiopia. The team visited research centers in Holetta (highlands), Debre Zeit and, Kulumsa (midlands), and Arsi Negele (lowlands). Kulumsa, together with the highlands of Meraro and Asasa plains, represent about 60-70% of the wheat area in Ethiopia. Â âThese are important sites for wheat breeding activities in Ethiopia. Given that Holetta and Debre Zeit are hot spots for diseases, there is an increased interest in the Arsi Negele region to expand wheat production under irrigated conditions,â said Bekele Abeyo, wheat breeder and CIMMYTâs Ethiopia Country Representative.
AGG Maize and Wheat Improvement Teams Meet with Partners to Develop CG-NARES Breeding Strategy
In the first fortnight of September 2023, researchers from the International Maize and Wheat Improvement Center (CIMMYT) and National Agriculture Research and Extension System (NARES) met in Nairobi, Kenya to create high-level strategies and guiding principles for CG-NARES breeding activities. This is in alignment with the âGenetic Innovationsâ initiative of the One CGIAR strategy. CIMMYT representation included breeding teams from the wheat, maize, and dryland crops. The meetings were organized by Bill & Melinda Gates Foundation and CIMMYTâs Accelerating Genetic Gains in Maize and Wheat (AGG) project team.
It was recognized that the aforesaid strategies and principles need to be based on the biology of the crops and the context of each breeding program; incorporate the logistics of the breeding operations; and implement data driven tools for decision making such as genomic selection.
Participants shared how the application of novel and innovative technologies shortens the breeding cycles, accelerates the rate of genetic gain, and provides tools to enable the evaluation of plant materials (future variety candidates) and future target environments where these varieties will be grown.
It was concluded that effective breeding networks can be a strong instrument to enable faster delivery of improved germplasm to farmers. For this to happen efficiently, the networks require a high degree of coordination, organizational structure, governance, and clarity of roles. âIt is fundamental for network members to agree the objectives, vision and expected outcomes of collaborative activities. This forms the basis for co-design and co-implementation of crop improvement plansâ said Kevin Pixley, Interim Director of the Global Wheat Program and Director of the Dryland Crops Program.
The meeting also served as a platform for AGGâs and dryland cropâs breeding teams to exchange ideas and experiences. For instance, the Maize team shared their experience and learnings from on-farm-testing activities. The Wheat team shared the evolution and path of breeding modernization and implementation of new technologies. The Dryland Crops team shared their experience with co-designing and co-implementing breeding networks with NARES partners in Africa.
