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.

SophiA Project Upgrades Medical Infrastructure at Buvuma Health Centre IV, Trains Technicians for Maintenance Works
Overview of the Sustainable Off-Grid Solutions for Pharmacies and Hospitals in Africa (SophiA) Project
Despite ongoing urbanization across Africa, the majority of the population still resides in rural and remote areas, where infrastructure development remains limited. These regions face significant challenges such as lack of access to healthcare, education, clean water, and reliable electricity, contributing to higher rates of illness and poverty compared to urban centres. According to reports, Sub-Saharan Africa has approximately 120,000 public health facilities (22,000 hospitals and 98,000 health posts), of which around 26% lack any electricity access, and only 28% have reliable power supply.
Access to good healthcare is critical for sustainable development. However, many rural medical centres operate under harsh conditions – using polluted water, lacking cooling for medicines, and facing poor sanitation – largely due to unreliable electricity and water supply. Although half of the population in Sub-Saharan Africa lacks electricity, the region has abundant renewable energy potential that can be effectively harnessed through off-grid solar photovoltaic (PV) systems.
To address the above-mentioned challenges facing the African Continent, Makerere University in partnership with 13 organizations across Europe and Africa developed a project titled, “Sustainable Off-grid solutions for Pharmacies and Hospitals in Africa (SophiA)”. The five-year project that began on 1st October 2021 is funded by the European Union (Project: 101036836 – SophiA – H2020-LC-GD-2-3-2020). At Makerere University, the project is coordinated by Dr. Nicholas Kiggundu, Associate Professor in the Department of Agricultural and Biosystems Engineering, College of Agricultural and Environmental Sciences (CAES).
Piloted in Burkina Faso, Cameroon, Malawi, and Uganda, SophiA aims to provide sustainable off-grid energy solutions to rural and remote health facilities, fostering economic growth and ensuring equitable access to energy and healthcare. Using various technologies, such as photovoltaics, solar thermal, electrical and thermal storage, water treatment and natural refrigerants with low global warming potential, SophiA has developed and manufactured locally innovative, modular, affordable and efficient solar powered systems for providing:
- Safe and clean drinking water, free of bacteria and viruses, and deionised water for medical purposes;
- Hot water and steam production for thermal requirements of the hospitals;
- Cooling of medicines and food at +5°C;
- Low temperature storage of blood plasma and vaccines at -30°C;
- Ultra-low temperature storage of sensitive medication (e.g. some Covid-19 or Ebola vaccines) at -70°C.
In addition, PV MedPort, a simple and 100% solar-powered solution has been developed and tested as a mobile health care station in small remote areas in 4 different geographical conditions in Africa. The SophiA system has been manufactured in Africa and will provide, for the first-time, innovative solutions based on climate-friendly natural refrigerants to cover cooling demand for three different temperature ranges (-70°C, -30°C and +5°C). The system has been tested and demonstrated at four rural hospitals in remote regions throughout the African continent covering the major geographical regions and different climatic conditions in Burkina Faso, Cameroon, Malawi and Uganda.
SophiA Project initiatives in Uganda
In Uganda, all Health Centre IV hospitals with surgical theatres have been connected to the national grid except Buvuma Health Centre IV, which serves over 120,000 people scattered across 52 islands. Recognizing this gap, the Ministry of Health selected Buvuma Health Centre IV for the SophiA project to demonstrate sustainable off-grid solutions.
The SophiA System at Buvuma Health Centre IV provides the following services:
- Off-grid electricity supply
- Safe, clean drinking water for patients, staff, and the community
- Hot water and steam systems crucial for maternal care
- Solar-powered cooking and meal preparation
