New Project to Improve Relevance of CAES PhD Graduates
Working with potential future employers of PhD students in Kenya and Uganda, Advancing Sustainable Agricultural Value Chains through Strengthening Trans-disciplinary Skills and Cooperation in East African Doctoral Education (ADVALUE) Project aims to develop curricula that best prepare academic specialists in agricultural sciences for their careers.
Overview
The lack of skills-oriented training significantly undermines the relevance of doctoral graduates in today’s rapidly evolving job market, particularly within industries such as agriculture, where practical expertise and adaptability are essential. While doctoral programmes traditionally emphasize research and theoretical knowledge, they often fail to equip graduates with the hands-on, industry-specific skills needed to address real-world challenges. In agricultural value chains, for instance, the ability to apply advanced research to optimize production, supply chain management, sustainability practices, and technological advancements is crucial. Without a strong foundation in these practical areas, doctoral graduates may struggle to effectively contribute to innovation and efficiency in agricultural systems. From improving crop yields through data analysis to enhancing logistics and distribution methods, agricultural value chains require professionals who can seamlessly integrate research with practical application.
What the ADVALUE Project targets to address
Co-funded by the European Union, the ADVALUE Project—Advancing Sustainable Agricultural Value Chains through Strengthening Trans-disciplinary Skills and Cooperation in East African Doctoral Education—seeks to modernize doctoral education in agricultural and agro-environmental sciences at universities in Uganda and Kenya. This initiative aims to enhance trans-disciplinary skills to promote the development of sustainable agricultural value chains, addressing pressing challenges such as food insecurity, unemployment, and climate change.
Project partners include; Nuertingen-Geislingen University, Germany (NGU); German Institute for Tropical and Subtropical Agriculture (DITSL); Czech University of Life Sciences Prague (CZU); Swedish University of Agricultural Science (SLU); Makerere University, Uganda; Uganda Christian University (UCU); University of Nairobi, Kenya (UoN); Pwani University Kenya (PU); Regional Universities Forum for Capacity Building in Agriculture, Uganda (RUFORUM). Associated Partners: European Alliance in Agricultural Knowledge for Development, Belgium (AGRINATURA); National Agricultural Research Organization, Uganda (NARO); National Council of Higher Education, Uganda (NCHE); Kenya Agricultural and Livestock Research Organisation (KALRO); Ministry of Education Science and Technology Kenya (MoEST). The project PI is Prof. Dr. Heinrich Schüle. In Uganda, the project is coordinated by Prof. John Tabuti.
Project objectives
- Develop innovative courses on trans-disciplinary research methodologies and value chain analysis within doctoral programmes.
- Strengthen collaboration with key stakeholders to ensure research is demand-driven and fosters innovation.

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
