ICOPSEA Project Supports Production of Quality Sweet Potato Planting Material
Published
4 years agoon

Sweet potato is an important root crop in East African countries. In some communities, it is a vital staple crop. The crop plays a significant role in the farming and food systems in East African countries and has a number of health benefits. The Vitamin A orange-fleshed cultivars are important in alleviating Vitamin A deficiency in children and expectant mothers. The crop also has potential for increasing household income through selling of vines, fresh tubers, and processed products such as puree and flour that are used in confectionaries. Largely, the crop has potential to contribute to food and nutrition security, as well as wealth creation. However, sustainable production of sweet potato is limited, by among other factors, diseases particularly those of viral origin like the sweet potato virus disease. Worldwide, over 30 viruses infect the crop.

Since 2006, a consortium of scientists from the Department of Agricultural Production, Makerere University; Uganda National Agricultural Research Organization, Jomo Kenyatta University of Agriculture and Technology (JKUAT); Tanzania Agricultural Research Institute Mikocheni (TARI-M), Addis Ababa University, and Rwanda Agricultural Board has been working to address the challenge with the aim of contributing to food security and economic development of the East African countries. Through a project titled;“Towards Sustainable Cassava and Sweet Potato Production in East Africa” funded by SIDA under the East African Regional Programme and Research Network for Biotechnology, Biosafety and Biotechnology Policy Development known as BIO-EARN (2006-2010), the researchers set out to generate technologies as well as strengthen human resource capacity to facilitate sweet potato genetic improvement and clean seed production. In 2011, the Consortium, through a SIDA- funded project titled;“Enhancing Food Security through Improved Seed Systems of Appropriate Varieties of Cassava, Potato and Sweet Potato Resilient to Climate Change”, evaluated and deployed the elite varieties of sweet potato that are adapted to climate change in diverse agro-ecologies. They also developed and institutionalised efficient sweet potato seed multiplication and delivery systems. Through these two projects, the researchers identified appropriate varieties of sweet potato seed, and developed disease diagnostic protocols and rapid multiplication techniques with the aim of promoting use of high quality sweet potato planting material.

The ICOPSEA Project
Following the achievements in the first two projects, SIDA through the BioInnovate Africa Programme in 2018 extended more funding to the Consortium to support the commercialization of the sweet potato seed value chain. The project titled; Integrating ICT in Commercial Production of Quality Sweet Potato Planting Material in East Africa (ICOPSEA) aimed to contribute to enhanced food and income security among smallholder farmers in East Africa. It also aimed to develop a sustainable private-sector-led sweet potato system in East Africa with enterprises developed along the seed value chain.

Specific objectives of ICOPSEA Project
- Ensuring that adequate quantities of quality sweet potato seed are available for smallholder farmers in East Africa
- Developing a field-based disease diagnostic kit for sweet potato seed quality control
- Designing a sweet potato web-based mobile app (ViaziVitamu App) to facilitate access to information, seed inspection, as well as monitoring of production and marketing of the sweetpotato seed
The three-year project implemented between January 2018-June 2021 was headed by Prof. Samuel Kyamanywa from the Department of Agricultural Production, CAES, Makerere University. Other members on the project included; Prof. Elijah Ateka from Jomo Kenyatta University of Agriculture and Technology (JKUAT); Dr SettumbaMukasa, Director SENAI Farm Supplies Limited, Uganda; Ms. Ann Kitisya, Director MIMEA International Kenya Limited; Dr Fred Tairo, Principal Agricultural Research Officer, Mikocheni Agricultural Research Institute (MARI) Dar es Salaam, Tanzania; and Dr. Placide Rukundo, Research Fellow, Roots and Tubers, Rwanda Agricultural Research Board.

Project Closing Meeting and Achievements Registered
At the project closing meeting held on 7th April 2022 in the School of Food Technology, Nutrition and Bio-Engineering Conference Room at Makerere University, the researchers led by Prof. Kyamanywa highlighted the achievements registered including; identification of 24 varieties for commercial certified seed production; development of an institutionalised commercial sweet potato seed system in East Africa- involving Universities and National Agricultural Research Institutes as providers of clean seed to private companies that sell to vine multipliers; and involvement of Government phytosanitary and certifying agencies in ensuring high quality seed is available for the farmers. Other achievements included; the development of infrastructure to support seed production, a field-based disease diagnostic kit for detecting viruses and different varieties of puree and flour used in confectionary industries. The project also supported the training of five MSc students and one PhD in crop science, agricultural economics, rural development, and data communication and software engineering. The team also developed a web-based mobile app to facilitate access to information, seed inspection and monitoring of production and marketing of the sweet potato seed. According to Dr. Drake Mirembe, the Viaz app tracks extension service delivery using a garden mapping module. It also supports on farm reporting.

The researchers are working towards strengthening linkages between the seed growers, tuber producers, processors and consumers. Plans are also underway to strengthen the inspection and certification process and having positive reinforcements for non-users of clean seed.
In his remarks, Prof. Kyamanywa appreciated SIDA and BioInnovate Africa for the significant support extended towards projects at CAES and Makerere University in general. He also appreciated the partners for their contribution in the implementation of the project.
Remarks by the Guest of Honour
Addressing participants, the Commissioner in charge of Crop Inspection and Certification at the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF), Mr. Paul Mwambu applauded the researchers for the great initiative, saying it would largely address challenges of food insecurity in the country, but also increase foreign export earnings. “Sweet potato is a very important crop for our country in terms of food and nutrition security but also income generation. The crop is increasingly becoming a major foreign exchange earner. In a week, we export 30 tonnes of sweet potato through Entebbe Airport alone, and if you assess exports by sea, they could be five times more. For these strategic reasons, the Ministry is going to carry forward the products generated out of the project because they make economic sense,” he noted. He further explained that the products generated from the project would largely decrease expenditure on importation of wheat which currently stands at UGX400 million per year. “As advised by the researchers, blending sweet potato and cassava flour with wheat in the confectionary industries can reduce expenditure on the importation of wheat. If we blend by at least 30%, we shall create market for the local farmers,” he noted.

He called for more investment in the production of quality planting materials to increase the value Ugandan products on the world market and to limit post-harvest losses.

Makerere University’s Department of Geography, Geo-informatics and Climatic Sciences in partnership with Quadrature Climate Foundation and Red Cross Red Crescent Climate Centre are seeking two fellows for Quadrature Climate Foundation (QCF) Fellowship Programme. This is a two-year post-doctoral programme fully funded by QCF, which is an independent charitable foundation working for a greener and fairer future. Applications for the two-year post-doctoral fellowship are invited from individuals with demonstrated interest and expertise in locally led adaptation to climate change research. This initiative is a unique and excellent opportunity to expand the network of interested individuals with researchers and decision-makers, as well as deliver action-oriented research to inform policy and practice. Depending on their interest, each applicant should choose one of the two thematic areas offered under the fellowship program:
- Knowledge co-creation for locally led adaptation to climate change
- Decentralised decision making for effective climate change adaptation and resilience
The Fellow working on the Thematic Area 1: knowledge co-creation for locally adaptation will explore collaborative learning processes (including informal learning) for climate change adaptation among smallholder farmers with focus on Uganda, with linkages to related work in Bangladesh, Mozambique and Napal. The overall intention is to generate understanding of how decision making processes, across scales, can be linked to local and context specific knowledge systems and process for epistemic just adaptation. The key research questions are:
- What does the process of co-creating knowledge for locally led climate change adaptation look like in a rural smallholder farming setting of a Least Developed Country (LDC)?
- What are the possibilities, promises and pitfalls of knowledge co-creation for locally led adaptation planning?
The research will intentionally contribute to methodological and practice advances in co-creation of knowledge for locally led climate change adaptation.
The research on Thematic Area 2: decentralized decision making for effective adaptation and resilience will undertake scientific interrogation of a climate finance mechanism that has been designed for locally led adaptation and resilience in Uganda. The Fellow will largely focus on testing selected assumptions behind the design of the mechanism. The key questions are:
- How does effective locally led climate change adaptation and resilience building investment decision making look like in practice?
- What works and how does it work? What does not work and why?
Key considerations in the research will include local leadership, inclusion, context specificity, cross-scale, and capability strengthening. The targeted contributions of the fellowship include improved knowledge management for climate resilience planning and decision-making, strengthened evidence-based research-policy-practice dialogues, framework(s) for integrating local and experiential knowledges in resilience building investment decision making processes, among others.
The Fellows will be based, full-time, at Makerere University, Kampala as a core member of the team working on locally led adaptation and resilience. Their work will be conducted under the auspices of the Least Developed Countries Universities Consortium on Climate Change (LUCCC) through which Makerere University is engaged in research and knowledge management collaborations.

CPUg Project Equips Waste Management Personnel with Essential Skills
Published
4 weeks agoon
April 2, 2026
*****The two-day training, hosted by the College of Agricultural and Environmental Sciences (CAES) at Makerere University, was conducted under the auspices of the APPEAR Collaborative Research Project, ‘Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg).
The challenge of waste management in Uganda
Fecal Sludge Management (FSM) and Solid Waste Management (SWM) are essential for building healthy, resilient communities. However, in many parts of Uganda, these systems remain underdeveloped, leaving communities exposed to a wide range of complex challenges.
Improper handling and disposal of fecal sludge and solid waste pose both immediate and long-term public health risks, including the spread of waterborne diseases like cholera, typhoid, and dysentery. When human waste is not safely contained, treated, or disposed of, pathogens can contaminate water, food, and soil, disproportionately affecting vulnerable groups such as children and residents of informal settlements.

Environmentally, unmanaged waste degrades ecosystems, pollutes rivers and wetlands, and contributes to greenhouse gas emissions. Open dumping clogs drainage systems, heightening urban flood risks and facilitating disease transmission. Non-biodegradable materials, including plastics, can persist for decades, blocking waterways, harming wildlife, and weakening communities’ resilience to climate change.
The economic consequences are equally profound. Inefficient waste management undermines productivity by driving up healthcare costs, lowering property values, and limiting tourism and investment opportunities. Informal waste collection systems, often the only coping mechanism for many urban residents, fail to provide adequate protection for workers.

Given these intertwined health, environmental, and economic impacts, the burden of fecal sludge and solid waste in Uganda is not merely a municipal concern but a pressing national development issue. Urgent attention is required to invest in modern FSM and SWM infrastructure, promote behavioral change, and implement regulatory frameworks that ensure safe, sustainable, and inclusive waste management solutions. Without such interventions, the compounded risks to human well-being, ecosystems, and economic growth will continue to escalate.
Addressing the Challenge through the CPUg Project
The Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg) Project, a collaborative initiative between the CAES, the Institute of Water Quality and Resource Management at Vienna University of Technology in Austria, the Department of Environmental and Livelihood Support Systems at Mbarara University of Science and Technology (MUST), and the Uganda Red Cross Society, seeks to tackle Uganda’s most pressing challenges in waste management.

The project set out to explore circularity concepts, test a variety of techniques for utilizing dried fecal sludge, analyze plastic recovery from existing composting plants, and evaluate the social and economic viability of improved FSM and SWM and their influencing factors on regional communities. Supported under the Austrian Partnership Programme in Higher Education and Research for Development (APPEAR), the project aims to examine how best to optimize and integrate FSM and SWM in rural settings in Wakiso District, refugee settlements in Arua District, and Uganda in general.
In addition to the technical aspects, the socio-economic viability of improved fecal sludge and solid waste management is being evaluated in terms of affordability, perceptions, and the willingness to accept and utilize these products. The project aims to contribute towards reshaping Uganda’s landscape through integrated solutions, scientific rigor, and inclusive community engagement. It stands as a model for integrated development.

It is coordinated by Prof. Jeninah Karungi Tumutegyereize from the Department of Crop Science and Horticulture at CAES, Makerere University.
Two-Day Training on Integrated Fecal Sludge and Solid Waste Management
The College of Agricultural and Environmental Sciences at Makerere University, in collaboration with the Uganda Red Cross Society, Mbarara University of Science and Technology, and Vienna University of Technology, Austria, held a comprehensive two-day training on Integrated Fecal Sludge and Solid Waste Management.

The training, conducted on 30th-31st March 2026, at Makerere University was officially opened by the Principal of CAES, represented by Dr. Mildred Ochwo Ssemakula, Head of the Department of Crop Science and Horticulture. Participants included representatives from academia, the private sector, municipal authorities, service providers, and farmers.

The training programme aimed to equip personnel across the waste management value chain with the knowledge and skills to transform fecal sludge and solid waste into valuable, sustainable agricultural and economic resources. It covered topics such as occupational safety, waste management infrastructure, processing and post-treatment methods, composting, carbonization, material flow analysis, service gaps, and economic considerations in Greater Kampala. Participants were also trained in specialized software tools designed to enhance efficiency and manage waste-to-resource processes, promoting both environmental sustainability and economic viability.
Particular emphasis was placed on shifting perceptions of fecal sludge-based products among end users, mainly subsistence and commercial farmers.

Emerging Issues from the Training
- Weak fecal sludge management systems: Existing systems, particularly in refugee settlements, are inadequate.
- Public health risks: Improper sludge handling continues to threaten health – only 44% of fecal sludge is safely managed.
- Limited technical capacity: Practitioners need more training in safe handling and reuse technologies.
- Low adoption of resource recovery: Sludge-to-product innovations are underutilized.
- Environmental pollution: Untreated sludge contaminates soil, water, and surrounding ecosystems.
- Poor integration with agriculture: Opportunities for nutrient recycling are not fully exploited.
- Inadequate equipment: PPE, emptying tools, and treatment facilities are scarce.
- Low composting standards in Uganda: Composting often follows non-scientific methods.
- Behavioral and hygiene gaps: Handwashing and proper waste disposal practices remain weak.
- Underdeveloped waste-based value chains: Compost, briquettes, and fertilizers are not economically leveraged.
- High reliance on on-site sanitation: Sewer network coverage is below 10% in Greater Kampala.
- Insufficient emptying and collection services: Services are limited and costly.
- Limited private sector engagement: Public investment and private participation are inadequate.
- Treatment capacity and cost recovery challenges: Facilities are strained and revenue mechanisms weak.
- Low willingness or ability to pay: Users are reluctant or unable to afford improved services.
- Negative perceptions of fecal sludge products: Public attitudes hinder adoption.
- Regulatory and equity barriers: Awareness is limited, regulations are burdensome, and access is unequal.

Way Forward
Effective waste management is essential for public health, yet remains a significant challenge in Uganda, with few households able to empty their on-site sanitation facilities due to high costs. Experts emphasize the need for increased investment and prioritization of operator safety. Rigorous safety protocols and training are critical to safeguarding workers and ensuring sustainable operations.

Remarks by the CAES Leadership
On behalf of the Principal of CAES, Dr. Mildred Ochwo Ssemakula underscored Uganda’s immense potential to benefit from effective fecal sludge and solid waste management. “In an agriculture-dependent country, converting waste into organic fertilizer and other resources can significantly enhance productivity and generate substantial economic benefits. At the CAES, we are proud to collaborate and support initiatives like CPUg through innovative research and capacity-building programmes that directly address Uganda’s environmental challenges. I extend my sincere gratitude to the researchers and partners for their unwavering commitment to advancing research and environmental management. Makerere University highly values these collaborations, and together, we form a powerful coalition driving positive change in Uganda’s development.”

The CPUg project has contributed to capacity-building by training five PhD students, three from Makerere University and two from Vienna University of Technology, as well as three MSc students from Makerere University. The results are expected to improve knowledge in waste management and strengthen stakeholder capacity across the waste management value chain.
