Soybean Breeders Deliberate Strategies for Improving Productivity
The breeders from USA, Brazil and across Africa, including scientists from CGIAR met at Makerere University on 28th November-1st December 2023 to share experiences, best practices and ideas on collaboration, and to brainstorm on ways of improving productivity.
Overview
Soybean (Glycine max) serves as one of the most valuable crops in the world, not only as an oil seed crop and feed for livestock and aquaculture, but also as a good and cheap source of protein for human diet and as a biofuel feedstock. The protein content of soybean is the highest among legume crops, averaging 40% on a dry matter basis. Soy-foods are generally considered to be nutritious and healthy based on their nutrient composition which includes protein, fat, carbohydrates, dietary fibres as well as minerals and phytoestrogens (or isoflavones). Due to its nutritional superiority, soybean-based foods are highly recommended for children under 5 years, expectant mothers, and HIV/AIDS patients. Impact studies have shown that regular soy food consumption can reduce the risk of heart disease by lowering serum cholesterol by about 33%. It can also reduce the risk of rectal cancer by 80%, mammary tumour by 40%, and breast cancer by 50%.
Economic viability
Production of soybean stands at 264 million MT worldwide, with United States of America (USA), Brazil and Argentina being the largest producers. In Africa, Nigeria, South Africa, Zambia and Uganda are the largest producers, with annual volumes estimated at 1.5 million metric tonnes (FAO, 2017). The Soybean Market size is estimated to reach $259 billion by 2030 (IndustryARC – Soybean Market Forecast 2023-2028).
The economic viability of soy production is determined by the commercial utilization of both its sub-products, meal and oil, which, respectively, account for about two thirds and one third of the crop’s economic value. Soymeal accounts for over 60% of world output of vegetable and animal meals and occupies a prominent position among protein feedstuffs used in the production of feed concentrates, while soybean oil is the single most important vegetable oil, accounting for 20% of global vegetable oil production. The widespread use of soybean oil in particular as edible oil is mainly due to (i) its plentiful and dependable supplies, (ii) its competitive price, (iii) its neutral flavour, and its stability in both unhydrogenated and partially hydrogenated form. Indirectly, the rapid rise in the demand for compound feed has contributed considerably to the rise in soybean and soyoil production. Soybean contributes significantly to the total value added by the agricultural sector in the major producing countries and particularly so in Brazil, Argentina, Paraguay and the USA. In these countries, soybean and its two main sub-products also occupy an important position in export earnings from agriculture as well as in terms of total merchandise exports (FAO). In Uganda, soybean is number one income earner crop in Northern and Eastern Uganda. Farmers in the region earn at least UGX1,200,000 per hectare per season.
Challenges undermining productivity
Despite the significant strides registered by soybean growing countries, and the health and economic benefits that the crop presents, a number of challenges still undermine productivity. These include; pests and diseases, prolonged droughts and prolonged rains, poor agronomic practices, inaccessibility to good seed by farmers, drudgery in the production chain (Planting and harvesting) and market price fluctuations, as well as mismatches in supply and demand. Surging input costs, supply disruptions of fertilizers and alternative crops caused by Russia’s invasion of Ukraine and lingering COVID-19 effects have added more uncertainty and volatility to the soybeans market, driving up the prices. Home grown technologies, local seed business approach, and addressing the whole value chain, are envisaged as some of the strategies to overcome the challenges. Adapting crop management, conserving and improving soil conditions by minimizing tilling, increasing crop diversification, protecting soil from erosion, as well as the development of drought-tolerant varieties, will be key to withstand the emerging climate challenges.
Soybean Breeders meeting at Makerere
Soybean breeders from USA, Brazil, and across Africa including scientists from CGIAR on 28th November 2023 met at Makerere University to share experiences, best practices, and ideas on collaboration, and to brainstorm on ways of improving soybean productivity. The meeting held at the School of Agricultural Sciences (SAS), College of Agricultural and Environmental Sciences (CAES) was organized by the Makerere University Centre for Soybean Improvement and Development (MAKCSID) and the Soybean Innovation Lab (SIL) of the University of Illinois with support from USAID. It was coordinated by Prof. Phinehas Tukamuhabwa, Principal Investigator for the Soybean Breeding and Seed Systems at Makerere, and Prof. Brian Diers from SIL, University of Illinois. It was graced by the Principal of CAES, Prof. Gorettie Nabanoga, the Deputy Principal, Prof. Yazidhi Bamutaze, and the Dean, SAS, Dr John Baptist Tumuhairwe. During the meeting, participants shared progress reports of their respective institutions, highlighting the achievements registered in soybean breeding and seed systems, best practices, challenges undermining productivity, and strategies for improvement. In his presentation, Prof. Diers briefed participants on SIL breeding efforts, indicating that 20 varieties had been developed between 2019-2022 up from the 7 developed between 2013-2018. He also shared updates on the renewed funding from USAID, and the support extended towards new breeding programmes at IITA in Nigeria, IITA in Zambia, EIAR in Ethiopia, Makerere University, and SARI in Ghana.
Delivering a presentation on soybean research in Uganda, Prof. Tukamuhabwa noted that the country had registered significant strides with the production of six high yielding varieties namely; Maksoy IN, Maksoy 2N, Maksoy 3N, Maksoy 4N; Maksoy 5N, Maksoy 6N. Recent impact studies indicated that the new varieties developed by MAKCSID were the most planted and accounted for 93% of the soybean varieties grown by Ugandan farmers. Currently, Maksoy 1N is the most widely adopted variety by farmers, while Maksoy 3N has the largest quantities of foundation seed disseminated by the Centre. According to Prof. Tukamuhabwa, the Centre also established a state-of-the-art seed storage facility for early generation seed (Breeders and Foundation seed) and soybean germplasm used for breeding other varieties. Other facilities are soybean processing equipment (soycow) and Soybean roaster that are used to add value to soybeans. The growth of the soybean sub-sector in Uganda is mainly attributed to the availability of a wide range of improved varieties, government investment in soybean research, and increased private sector investment along the soybean value chain. Despite the achievements, Prof. Tukamuhabwa outlined a number of factors undermining soybean seed systems in Uganda including; the presumed high cost of seed by farmers, counterfeit seed in the market, limited interest in self-pollinating crops by most private seed companies, weak seed policy enforcement, limited access to seed, and unpredictable weather conditions. He expressed gratitude to all development partners that have supported the growth of the MAKCSID programme including; USAID through SIL, the Government of Uganda through the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF VODP), NARO, NAcRRI, RUFORUM, AATF, AGRA, Soybean Africa Limited, NAADS, Smart Foods, ISSD Uganda, IITA, and all local soybean stakeholders.
At the meeting, participants including Godfree Chigeza from IITA, Zambia; Abush Tesfaye (IITA, Nigeria), Masresha Yirga (EIAR, Ethiopia), Harun Murithi (SIL), Andrew Scaboo (University of Missouri), Elizabeth De Meyer (University of Missouri), and Carrie Miranda (North Dakota State University) delivered presentations on the progress of their breeding and research programmes.
A major concern arising from the meeting was the increasing threat of rust. Through efforts of the Centre for Soybean Improvement and Development (MAKCSID), the soybean rust pandemic was brought under control, through breeding and dissemination of superior varieties to the farming communities.
Going forward, participants emphasized the need to set up a rust reference centre, early warning systems, and disease nurseries – potential lines for monitoring virulence. They also called for an increase in germplasm acquisition, capacity building for germplasm storage and utilization, introduction of bruchid tolerant genotypes, introduction of soybean genotypes suitable for mechanical harvest, mechanization of production processes, leveraging the scarce research infrastructure, and the development of necessary skills amongst scientists and staff.
In her remarks, the Principal of CAES, Prof. Gorettie Nabanoga expressed gratitude to participants for leading soybean development initiatives. She also appreciated the development partners for supporting the programme. Commenting on the significance of the crop, she said under NDPIII, soybean had been identified as a game changer and one of the crops to improve the country’s food systems. “The crop has been targeted for its oils and nutritional benefits. It is therefore important that we move it to the next level in terms of resistance to diseases, adaption to climate change, and development of fast growing varieties.” She specifically thanked the breeding team led by Prof. Tukamuhabwa for making Makerere the leading Centre in quality soybean seed production and distribution in the country. During their four-day visit, the soybean breeders visited the screen houses, soybean fields, and the Early Generation Seed Unit at MUARIK where they provided enriching insights for improvement. The team also toured Nakabango/Jinja trials as well as the Bugi ZARDI highland soybean trials.

AfPEC Project Targets to Safeguard Ecosystems in the Mt. Elgon Region through Agroforestry
*****Funded by DANIDA, Agroforestry for People, Ecosystems and Climate Change (AfPEC), a five-year project (March 2024-April 2029) focusing on Mt. Elgon Highlands in Eastern Uganda aims to foster to use agroforestry to prevent climate change and loss of biodiversity in the region. The project will focus on four districts namely: Mbale, Bududa, Bulambuli, and Kapchorwa. Project Partners: Makerere University, Aarhus University & University of Copenhagen (Denmark), Youth Leading Environmental Change (YLEC), Seniors without Borders, Forests of the World, Stjernekommunikation, and FrellsenKaffe. Through the project, coffee farmers in the region will be supported to export their coffee to Denmark. The project team held the inception meeting on 25th-26th September 2024 in Mbale City.
Overview
Climate change and biodiversity loss are emerging as two of the greatest environmental challenges facing humanity. In Uganda, natural ecosystems such as forests and wetlands contribute considerably to people’s livelihoods and the national economy. However, rapid population growth has led to the degradation of these ecosystems due to increased demand for firewood and the conversion of land for agricultural purposes. Furthermore, the effects of climate change, including variable rainfall patterns and higher temperatures, are leading to a rise in the frequency and intensity of floods, droughts, landslides, windstorms and hailstorms (UNEP- Ecosystem-Based Adaptation in Uganda). Failure to tackle the effects of climate change threatens the achievement of the Sustainable Development Goals (SDGs), with catastrophic consequences that will hit the poorest and most vulnerable communities first and hardest (UCL Global Governance Institute, 2021). The United Nations Decade on Ecosystem Restoration 2021-2030 is a rallying call for the protection and revival of ecosystems around the world, for the benefit of people and nature. It aims to halt the degradation of ecosystems, and restore them to achieve global goals.
Agroforestry as a climate change adaptation strategy
Agroforestry, the purposeful integration of trees or shrubs with crops and/or livestock at the plot, farm, and/or landscape scale, is one potential climate change adaptation strategy to increase the resilience of farmers and agricultural systems against climate risk, providing a range of biophysical and socioeconomic benefits. As highlighted by the Intergovernmental Panel on Climate Change (IPCC) reports of 2022, agroforestry is a promising agro-ecological approach to climate change adaptation because of the multitude of co-benefits that many agroforestry systems provide including, enhanced food security and income opportunities, the provisioning of ecosystem services, and biodiversity conservation (Amy Quandt, et.al 2023). Agroforestry significantly impacts the environment in diverse ways that contribute to both global environmental goals and local sustainability. Despite of the benefits, promotion, implementation and sustainability of agroforestry practices is still not well addressed.
Purpose of the AfPEC project
Coffee farmers in the Mt. Elgon Region in Eastern Uganda have traditionally with success used agroforestry that protects important water catchments and biodiversity hotspots, but these areas now experience degrading soils caused by external factors such as forest loss, soil erosion and population growth. Changes in climate have also affected farming conditions favouring more drought-resistant crops and agroforestry systems with well-developed shade. Agroforestry for People, Ecosystems and Climate Change (AfPEC), a new project funded by DANIDA aims to understand the factors that motivate coffee farmers to engage in agroforestry, and to foster the use of agroforestry to minimize the effects climate change and loss of biodiversity in the region. Specifically, the project aims to document the effects of agroforestry in terms of ecosystem services and livelihood benefits, to understand motivating factors for long-term sustainable development, and to support science-based agroforestry in practice. The project will focus on four districts namely: Mbale, Bududa, Bulambuli and Kapchorwa.
Specific objectives
The project will be implemented though five work packages in line with the objectives below;
1.Quantifying the potential of agroforestry in terms of ecosystem services – Under this objective the focus is to assess the benefits of various agroforestry systems, including carbon sequestration, biodiversity conservation, and other ecosystem services. This research will help stakeholders understand the potential and limitations of different agroforestry approaches and contribute to mitigating climate change and biodiversity loss. Additionally, the findings will be used to select suitable native tree species for planting in highland coffee agroforestry systems.
2.Identifying livelihood benefits from agroforestry and key factors for long-term sustainable development.
3.Channelling scientific knowledge on agroforestry into practice –Given the urgent threats posed by biodiversity loss and climate change in Africa, it is imperative to translate scientific research into practical solutions. In collaboration with NGOs and local farming communities, the project team will disseminate user-friendly information and ensure that research findings directly benefit livelihoods and ecosystems. The goal is to increase local income through sustainable coffee production, carbon credits, and potentially, emerging markets for ecosystem services.
4. Building multidisciplinary capacity at university level –The project will train four PhD students from Uganda, and at least 12 master students from Denmark.
5. Promoting optimized agroforestry systems widely.

The meeting was attended by 52 participants including the project team, farmers from participating districts, RDCs from participating districts, representatives from the participating NGOs – Seniors without Borders, Youth Environmentalists leading Environmental Change (YLEC) and Forests of the World, and Graduate students attached to the project.
Presentations/remarks by the project team
In his welcome address, Prof. Frank Mugagga, one of the project coordinators at Makerere University appreciated participants for honouring and turning up for the workshop, noting that it was important for the team to establish a working relationship for smooth implementation of the project. Outlining the importance of research and partnerships towards the vision and mission of Makerere University, he expressed gratitude to the funders, and the Project PI, Dr Anne Mette Lykke for her unwavering efforts towards securing the grant.
Presenting an overview of the project, the lead Coordinator in Uganda, Prof. John Tabuti explained that although agroforestry systems have been around for long, their contribution has not been well understood and adopted. Discussing the different work packages, Prof. Tabuti said the project would document both negative and positive impacts of highland agro-ecosystems to improve their contribution to ecosystems and livelihoods.
At the meeting, the Project PI, Dr Anne Mette Lykke briefed participants on ethics and the rules governing the DANIDA AfPEC Grant. She presented the partnership grant agreement, highlighting the research ethics considerations, rules on publications, communication and dissemination requirements, and data sharing and management as guided by DFC. She urged the project team to familiarise themselves with the regulations to ensure timely delivery of the intended outputs.
In his remarks, the representative of farmer groups in Mbale District, also Chairperson of Bufumbo Agroforestry Group, Mr. Hussein Mafabi appreciated the project team and funders, noting that the initiative would greatly improve their skills in agroforestry. Highlighting the factors fuelling environmental degradation in the region, Mr. Mafabi decried the lack of a clear policy on plastic waste management, calling for support to avert the crisis. He emphasized the need to translate the project results into actual policy changes to further collaboration beyond AfPEC. “AfPEC has the support of local communities who are eager and willing to participate in the project activities,” he noted.
During the workshop, representatives from the partnering NGOs including Seniors without Borders, Forests of the World, and YLEC shared their experiences working in the region, outlining success stories in coffee agroforestry that the AfPEC project can leverage to achieve its targets. Prof. Jørgen Axelsen briefed participants on the biological pest control processes, whereas Dr James Johns from Forests of the World delivered a presentation on biomass and carbon sequestration in Uganda’s smallholder agroforestry systems. Speaking to participants, Dr Poul Kroijer (Seniors without Borders) noted that through the AfPEC project, farmers in the region will be able to export their coffee to Denmark. The team expressed willingness to support the project activities.
Presentations by MSc and PhD students supported by the Project
AfPEC project will train four PhD students from Uganda, and at least 12 master students from Denmark.
During the workshop, three Masters Students from Aarhus University, Denmark and four PhD students from Makerere University who will be conducting research on different aspects of agroforestry in the Mt. Elgon Region, Eastern Uganda presented their research ideas to participants who provided enriching feedback. These are; Smilie Nielsen (MSc Human Security) who will be examining the factors that motivate young coffee farmers in Mt. Elgon Region to engage in agroforestry, Ms. Josephine Fogt Anderson (MSc Human Security) who will be studying women-nature relations in agroforestry and planting initiatives (How gender equality can be addressed in tree planting and agroforestry projects), and Ms. Matilda Willemoes who will be exploring the potential for carbon sequestration and storage in coffee Forestry systems.
The PhD students include Mr. Patrick Kayima who will study value chain and livelihood benefits of coffee agroforestry, and Ms. Patricia Adoch who will evaluate the influence of different management practices of coffee agroforestry systems on pollinators and pests in the Mt. Elgon Region. Ms. Joyce Lunyolo will conduct research on incentives for stewardship efforts in coffee agroforestry among farmers in the region, whereas Mr. Derick Kisegu will study and document the contribution of Arabica coffee agroforestry systems in mitigation and adaptation to climate change in fragile highland ecosystems of Uganda.
The students will be supervised by academics from the partner institutions namely: Prof Anne Mette Lykke, Prof. John Tabuti, Prof. Frank Mugagga, Dr. Josephine Esaete, Prof. Ida Theilade, Dr. Kellen Aganyira, Prof. Stine Kroijer, and Prof. Katrine GroFriborg.
Remarks by the Chief Guest
Addressing participants, the Deputy RDC Kapchorwa District, Mr. Martin Sakajja, on behalf of the Resident District Commissioners (RDCs) in the project area, expressed gratitude for the initiative noting that it holds immense significance for the country and world at large. “Agroforestry represents the fusion of agricultural productivity with ecological conservation—a synergy that is critical for sustainable development in our times. For generations, rural populations have depended on agriculture as their primary source of livelihood. Yet, we know the challenges farmers face: declining soil fertility, erratic rainfall, and dwindling forest resources. Agroforestry addresses these issues by promoting sustainable agricultural practices that not only enhance food security but also generate additional sources of income from forest products such as fruits, timber, and medicinal plants. Through this project, we envision empowering farmers to increase their yields while preserving the natural resources they rely on. By embracing agroforestry, we are not only reducing our vulnerability to climate change but also contributing to global climate goals. I commend Makerere University and all the partners involved in this project for their vision and dedication,” he noted.
Remarks by the representative of Makerere University
On behalf of Makerere University, Dr Henry Ssemakula appreciated the project team for the initiative noting that it aligns with the sustainable development goals (SDGs), the National Development Plan, and the Parish Development Model. “The project is also in tandem with our strategy of transforming Makerere into a research-led University responding to national, regional, and global development challenges, and contributing to global knowledge generation. Its commitment to capacity building through Masters and PhD trainings, community engagement, and internationalization is equally commendable.” He appreciated the funders for supporting AfPEC and several other projects in Uganda.
The workshop was moderated by Dr Josephine Esaete, Dr Vincent Muwanika, and Dr Kellen Aganyira from Makerere University.
On the final day of the workshop, the project team conducted a reconnaissance tour of three research sites namely; Bufumbo in Mbale, Buginyanya in Bulambuli District, and Sipi in Kapchorwa District.
