Mak-CAES BioInnovate Project Registers Significant Achievements

Published

on

Smallholder farmers in Uganda and Kenya produce a variety of fruits, traditional and exotic vegetables, spices, and herbs that have unique nutritional, nutraceutical and functional properties. However, the value derived from these crops is limited due to postharvest losses, seasonal production, limited value addition and market access problems. Developing and applying affordable food preservation technologies could reduce postharvest losses by up to 68%. Additionally, food preservation by drying not only prolongs shelf life, but it also minimizes storage, transportation and packaging costs.

About the project

In 2017, Makerere University through the Department Agricultural and Biosystems Engineering at the College of Agricultural and Environmental Sciences (CAES) received funding under the BioInnovate Africa Programme Phase II to implement a project titled;“Adaptation and Promotion of Refractance Window Drying Technology (RWDT) for Production of High Quality Bio-products”. The RWDT uses heat to dry fruits and vegetables, while maintaining the nutritive qualities. With RWDT, liquid foods, purees or slices are dried on one side of a thin plastic film, whose other side is in close contact with hot water at temperatures below boiling point. The plastic film, usually in the form of a conveyer, is susceptible to infrared radiation, therefore allowing thermal energy to be transferred from the water to the food. Transmission of infrared radiation stops when the food is dry, and the product scraped off the conveyor. The temperature of the product remains relatively low during drying, resulting in better quality retention due to reduced moisture content and inhibited microbial growth. The heated water is recycled, further improving thermal efficiency of the system.

Explaining the design process of the Refractance Window Dryer, Dr Julia Kigozi said the technology is mechanically simple, cheaper to purchase, energy efficient with high drying speed and low operational costs, and ensures retention of product quality. Dr Kigozi revealed that steps were being taken to promote the use of RWD technologies through Jazi Agro-processing Solutions Limited. Jazi Agro-processing Solutions Limited is a private company that specializes in food processing and doubles as a consultancy in regards to agro-processing solutions with a goal of promoting the agro-processing sector in Uganda. The company carries out training and mentoring on fundamentals necessary for the operation of agro-processing industries.

During the meeting, Mr. Raymond Mutumba shared the outreach and dissemination programmes conducted by Food and Nutrition Solution Ltd (FONUS) with regard to the Refractance Window Drying Technology.Based at the School of Food Technology, Nutrition and Bio-Engineering, Makerere University, FONUS provides consultancy services in the fields of food value addition, community nutrition, food handling and hygiene, post-harvest handling of foodstuffs, facilitation of farmer group learning processes and project evaluations.The main purpose of FONUS’ engagement with the project was to promote uptake of the RWD technologies among end users. This was done through a series of engagements with farmer groups, small and medium agro-processors, and processors that utilise the RWD products and ingredients in foods.

Community engagements undertaken by FONUS included a situational analysis on the potential utilization of the Refractory Window Drier Technology in food value addition, training agro-processors in the use of hybrid RWD, and training of medium and large scale agro-processors in the use of RWDT in the drying of fruits and vegetables. In addition, FONUS conducted trainings on the use of RWDT products and ingredients and flavours in foods, and assessed the marketability of RWDT products.

According to Mr. Mutumba, the community engagements revealed that the RWDT presented a viable solution for preservation of fruits and vegetables in Uganda. The engagements also revealed that the incubatees were more willing to adopt the technology compared to already established processors. It was also discovered that more research needs to be done in RWDT energy efficiency if the RWDT products are to have competitive process on the market. The team called for government support to increase uptake of the technology, noting that individuals and small processor groups may not easily afford it.

Addressing participants, the Vice Chancellor, Prof. Barnabas Nawangwe appreciated SIDA for the enormous support extended towards research and training programmes at Makerere University. “The University has reached the 1,000 mark of staff with PhDs, and almost half of these have been trained under SIDA,” he noted.  In addition to other research programmes, SIDA supports the BioInnovate Africa Programme. The Vice Chancellor applauded the Department of Agricultural and Biosystems Engineering at CAES for the commendable initiative aimed at improving the quality and increasing shelf life of agricultural products in Uganda. “The products produced out of this initiative can be major exports for Uganda. We need to move towards commercializing our products. We however need to improve our marketing skills,” he explained while cautioning the research team on the importance of marketing the products. He also advised researchers to make use of the Intellectual Property Management Office at the University to patent their products.

Commenting on the significance of agriculture in the development of the economy, the Vice Chancellor said the CAES has a great role to play in improving the sector. Appreciating the research output at CAES, he called on the College to take lead in the establishment of a central business incubation unit to promote research and innovation at Makerere.

In line with 2020-2030 Strategic Plan that aims to transform Makerere into a research-led University, the Vice Chancellor said it was time to do things differently. “At the moment, Makerere is a research-intensive not research-led University. We have excelled in research publications. We need to move towards churning out companies if we are to make positive impact on our economy. You can remain top on research while churning out companies,” he explained, sharing an example of the University of Istanbul that churns out 300 companies per year worth about three billion USD, and is greatly contributing to the development of the country’s economy. The Vice Chancellor echoed the need for Makerere University to make contribution towards the Parish Development Model. “We will be judged harshly if we do not do anything to liberate our people,” he said.

Policy Brief: Strengthening Climate Resilience and Livelihoods in Uganda’s Refugee and Host Communities

Published

on

Makerere-Cambridge project Communities of Hosts and Refugees Transitioning to Climate Resilience (CHART-CR) Workshop Participants, Kikuube district. The Communities of Hosts and Refugees Transitioning to Climate Resilience (CHART-CR) through workshops project focused on the interlinked dimensions of climate variability, food security, livelihoods, and water availability across diverse ecological contexts, including lowland refugee-hosting areas and mountainous, flood-prone regions through collaborative partnership between Makerere University Kampala Uganda, East Africa, University of Cambridge, and Cambridge-Africa Programme, with financial support from the Mastercard Foundation and Cambridge-Africa.

Uganda’s refugee-hosting and vulnerable communities in Kyangwali (Kikuube district, part of former greater Hoima district) and Kasese district face severe risks from climate change, population pressure, and resource dependence, undermining livelihoods, food security, and water, sanitation, and hygiene (WASH) outcomes. The Makerere-Cambridge project Communities of Hosts and Refugees Transitioning to Climate Resilience (CHART-CR) engaged communities through participatory research to identify adaptive practices, infrastructure gaps, and actionable strategies to address these issues.

Our findings are that integrated interventions including community training hubs for capacity building, climate-resilient infrastructure, and participatory resource governance can strengthen resilience, protect livelihoods, prevent potential conflicts, and support sustainable development.

More information: https://chart-cr.org/.

Key Messages for Policy

  • In Hoima District: Erratic rainfall patterns and prolonged dry spells are significantly affecting agricultural productivity and water availability, thereby threatening food security among refugees and vulnerable host communities.
  • In Kasese District: Frequent floods and landslides are causing widespread disruption to agriculture, damaging infrastructure, and compromising food security and WASH services, especially for refugees and vulnerable host populations.
  • Strengthening climate resilience requires combining infrastructure investments, community training, participatory governance, and livelihood support to address interconnected risks in food security, water, and sanitation.
  • Refugee and host communities already demonstrate adaptive practices such as soil conservation, intercropping, and water-efficient farming which can be scaled and reinforced through participatory learning platforms.
  • Women and children bear the brunt of water collection and household labor; inclusive strategies and equitable decision-making in WASH, agriculture, and resource management enhance both resilience and social equity.
  • Investments in climate-resilient infrastructure, integrated community hubs for knowledge exchange and capacity building, and participatory governance could strengthen adaptive capacity, secure livelihoods, prevent societal conflicts between communities and protect health, education, and sustainable development outcomes.

1. Background

Uganda hosts one of Africa’s largest refugee populations under a progressive policy framework that promotes inclusion and self-reliance. Within this context, Kyangwali Refugee Settlement in Hoima District accommodates approximately 155,000 residents, of whom 99.7% are refugees. Women and children constitute nearly 80% of the population, underscoring significant demographic vulnerabilities. Increasing population density, coupled with declining land availability per household, has intensified pressure on natural resources. This has contributed to environmental degradation and heightened exposure to recurrent droughts, thereby constraining agricultural productivity, worsening food insecurity, and increasing dependence on humanitarian assistance. The host communities suffer from the same environmental changes, and the fact that the refugee and host communities are managed separately add to suspiciousness between them that might lead to rising tensions and potential conflicts.

Similarly, Kasese District has an estimated 750,000 people who rely heavily on rain-fed subsistence agriculture, with over 85% of the population dependent on this livelihood system. The district is highly susceptible to climate-related hazards, including recurrent flooding, landslides, and droughts. These risks are particularly pronounced along River Nyamwamba and within the Kilembe mining areas, where environmental instability continues to undermine water and sanitation, infrastructure, disrupt livelihoods, and pose significant public health challenges. The convergence of climate variability, rapid population growth, and high dependence on natural resources creates a complex and reinforcing cycle of vulnerability affecting both refugee and host communities.

3. Climate Variability and Environmental Pressures Key Policy Issues

In Kyangwali, rainfall patterns have become increasingly erratic, with delayed rainy seasons and prolonged dry spells disrupting traditional planting and harvest cycles and significantly reducing yields. Deforestation associated with refugee settlement expansion has reduced soil moisture retention, biodiversity, and microclimate regulation, further undermining agricultural productivity.

Food Security and Livelihood Constraints

Shrinking per capita land provision, declining seed quality, limited access to farm inputs, and weak storage infrastructure constrain crop diversification and household self-reliance in both districts. Post-harvest losses and limited market access reduce household income, heightening vulnerability. Refugee-host interactions, including land rental, knowledge exchange, and market engagement, enhance resilience but might also create perceptions of inequality due to differences in institutional support.

Water Access and availability Challenges

Communities face water scarcity and contamination from communal usage, poor sanitation, and agricultural runoff. Women and children bear the primary burden of water collection, often traveling long distances, which reduces labor productivity and school attendance. In Kasese district, low latrine coverage, open defecation, and inadequate waste management increase exposure to waterborne diseases. Floods and landslides on Kasese further compromise water quality and availability and thus increase health risks.

Adaptive Capacities

Despite these challenges, communities demonstrate strong local knowledge and adaptive practices, including informal water management, soil conservation, intercropping, and water-efficient farming techniques. Participatory approaches, joint training in climate-smart agriculture, and collaborative livelihood initiatives foster social cohesion and knowledge sharing between refugees and host communities. Existing leadership structures, community awareness, and partial infrastructure provide a foundation for scaling resilience interventions.

4. Conclusions and Policy Directions

Climate variability, population pressure, and resource dependence significantly undermine livelihoods, food security, and Water Sanitation and Hygiene (WASH) outcomes in Kyangwali and Kasese. Communities possess valuable experiential knowledge, adaptive practices, and social cohesion; however, structural constraints including weak infrastructure, limited financing, low technical capacity, and fragmented coordination – limit the effectiveness of local strategies.

To strengthen resilience, integrated interventions are required that bridge humanitarian response and long-term development, institutionalize participatory and gender-sensitive approaches, build human, social, and institutional capital, and align local priorities with technical expertise and policy frameworks. Key policy measures include:

  • Establish and strengthen integrated community resilience centers that serve as hubs for capacity building, knowledge exchange, and practical training in climate-smart agriculture, environmental conservation, food storage, water management, and market access. These centers should also promote inclusive learning, skills development, and cooperative enterprises that support both refugee and host communities in developing sustainable livelihoods.
  • Invest in Climate-Resilient Infrastructure: Upgrade WASH systems, construct protected wells, boreholes, piped water networks, and communal storage facilities, and restore riverbanks through tree planting and drainage maintenance to reduce soil erosion and contamination.
  • Promote Community-Led Resource Governance: Support participatory water, sanitation, and agricultural management, including monitoring systems for adaptive learning, equitable resource allocation, and gender-sensitive decision-making.

These combined strategies will enhance adaptive capacity, secure sustainable development outcomes, and protect livelihoods, food security, health, and education for Uganda’s most vulnerable populations.

5. Call to Action

The experiences and lessons learnt from Hoima (Kyangwali Refugee Settlement and adjacent host communities) and Kasese (refugee and host communities living around River Nyamwamba) under the CHART-CR project highlight the urgent need for integrated, locally informed, and coordinated resilience strategies. By aligning technical expertise, policy frameworks, and community knowledge, stakeholders can enhance adaptive capacity, secure sustainable development outcomes, and protect livelihoods, food security, health, and education for Uganda’s most vulnerable populations.

*****Celebrating a Distinguished Scholar, Mentor, and Global Authority in Forestry and Sustainable Environmental Stewardship

It is with profound sorrow and a deep sense of loss that the Makerere University community mourns the passing of Prof. Abwoli Yabezi Banana, an outstanding scholar, teacher, researcher, mentor, and academic leader whose life was dedicated to the pursuit of knowledge, environmental stewardship, and human development. Prof. Banana passed on in the morning of 31st May 2026, leaving behind an enduring legacy that will continue to inspire present and future generations.

For more than four decades, Prof. Banana served Makerere University with exceptional commitment and distinction as an academic in the Department of Forestry, Biodiversity and Tourism, within the College of Agricultural and Environmental Sciences (CAES). Even after his retirement in 2024, his intellectual presence remained strongly felt across the University and beyond, reflected in the generations of scholars he trained, the institutions he strengthened, and the extensive body of knowledge he contributed to global academia.

As an educator, Prof. Banana was exceptional in every sense. He was admired for his clarity of thought, intellectual rigor, and his rare ability to stimulate curiosity and independent thinking among his students. His teaching transcended conventional classroom instruction; it encouraged critical reflection, ethical reasoning, and a deep sense of responsibility toward society and the environment. Many of his former students now occupy influential positions in academia, government, and professional practice, carrying forward the intellectual foundation and values he instilled in them.

Equally profound was his role as a mentor and guide. He dedicated considerable time and energy to nurturing students, early-career academics, and researchers, offering not only scholarly direction but also personal support grounded in humility, patience, and integrity. His mentorship was characterized by genuine care and attentiveness, often extending beyond academic work to include life guidance that emphasized discipline, perseverance, and moral responsibility. Those who interacted closely with him remember a mentor who combined intellectual excellence with deep humanity and approachability.

Prof. Banana will also be remembered for his calm and thoughtful presence, his collegial spirit, and his unwavering commitment to academic integrity. He embodied the principles of service, respect, and humility, consistently placing the advancement of others above personal recognition. Despite his numerous achievements and international standing, he remained grounded, approachable, and deeply committed to fostering a supportive academic environment where others could thrive.

His passing is a profound loss to Makerere University, to Uganda’s forestry and environmental science fraternity, and to the global academic community. Yet, his legacy remains firmly embedded in the institutions he helped shape, the policies he influenced, the ecosystems his work sought to protect, and the many scholars who continue to build upon his intellectual contributions.

As we reflect on his life, we also celebrate a journey defined by purpose, excellence, and service. Prof. Banana’s contributions will continue to echo through the forests he studied, the classrooms he transformed, and the communities whose understanding of environmental stewardship was enriched through his work.

We extend our heartfelt condolences to his family, friends, colleagues, former students, and all who were privileged to know him. May you find comfort in the extraordinary life he lived and pride in the lasting impact of his work and values.

Prof. Abwoli Yabezi Banana may no longer be with us physically, but his influence endures in the knowledge he created, the people he mentored, and the principles he so faithfully upheld.

May his soul rest in eternal peace.
