After 43 years of dedicated service to Makerere University, Prof. Elly N. Sabiiti, a prolific researcher and internationally recognized scholar, currently working at Busitema University–Faculty of Natural Resources and Environmental Sciences, retired from university service in 2021. On 2nd September 2022, Prof. Sabiiti, in company of his wife Joy Sabiiti delivered a valedictory lecture to staff at the College of Agricultural and Environmental Sciences (CAES), Makerere University. The lecture organized by the Office of the Principal, CAES and held in the Conference Hall at the School of Food Technology, Nutrition and Bio-engineering focused on his experiences, achievements, challenges, and strategies that enabled CAES to evolve from a Faculty to one of the most celebrated Colleges at the University. He specifically spoke about his career development in terms of teaching, research, graduate supervision, leadership, resource mobilization, representation on professional bodies, and outreach services, before sharing his thoughts for CAES to grow to higher levels and excel in Agricultural and environmental Sciences.
Addressing members of staff, Prof. Sabiiti noted that he was happy to be delivering his Valedictory Lecture at the time Makerere University is celebrating 100 years of existence and excellence. He appreciated Makerere University Management for providing a conducive environment and facilities that enabled him to excel to become an international professor. He equally appreciated all development partners who supported his academic journey. Having joined Makerere University in 1973 as an undergraduate student, Prof. Sabiiti rose through the ranks to become a professor in 1998. During his time at Makerere, Prof. Sabiiti served in various capacities and made enormous contribution towards the development of the College of Agricultural and Environmental Sciences (CAES) and Makerere in general. At the time of his retirement, he was serving as a Professor in the Department of Agricultural Production at CAES.
Academic contributions
At Makerere, Prof. Sabiiti had an illustrious career. He developed and taught several undergraduate and graduate courses namely; Undergraduate – Pasture Agronomy, Plant Genetic Resources and Utilization (developed), Seed Science and Technology (developed), Forest Fire Ecology, Agricultural Botany, Ecology and Crop Practical Skills. Graduate courses developed and taught by Prof. Sabiiti included Agronomy of Grasslands, Eco-physiology (developed), Seed Science and Technology (developed), and Plant Genetic Resources and Utilization. He played a key role in the transformation of the Agricultural Husbandry Forum to a Regional Forum based at Makerere University. He established collaboration at local and global levels with various institutions such as Swedish University of Agricultural Sciences, ILCA, AFRINET, ICRAF, NARO, ASARECA and this improved visibility of the Faculty of Agriculture and Forestry. Prof. Sabiiti supervised 33 graduate students, 26 MSc and 7 PhDs and had over 150 publications by the time he retired. He supervised and supported several members of staff to attain doctorates and to raise through the ranks to become senior lecturers and associate professors. These include, Dr Denis Mpairwe, an Assoc. Prof and former Head, Department of Agricultural Production; Dr Justine Kasozi Nambi, Senior Lecturer in the Department of Agricultural Production; Dr C Katongole, Senior Lecturer in the Department of Agricultural Production, and Coordinator Centre for Waste Management; Dr Sylvester Katuromunda, Senior Lecturer in the Department of Agricultural Production; Dr Jeninah Karungi-Tumutegyereize, an Assoc.

Kato, Associate Professor, Kyambogo University; and Dr S. Mugasi, ED, NAADS.
Curriculum Expansion
As Dean Faculty of Agriculture and Forestry, Prof. Sabiiti was instrumental in the review and expansion of academic programmes at CAES. “There used to be one MSc in Agriculture with options but these would not be reflected on the degree certificate so we revised the old curriculum and proposed specialized MSc degrees of the various options, MSc Crop Science, MSc Soil Sciences, MSc Animal Science, and MSc Agricultural extension and this increased post graduate numbers. I led the development of a highly popular program –Masters in Agribusiness Management that combined science courses with agricultural economics to produce agribusiness entrepreneurs and make agriculture a rewarding business. We also revised the undergraduate degree programme from three: Bsc Agriculture, BSc Food Science and Technology and BSc Agricultural Engineering to over 10 programs,” he noted. “By the time I handed over to the next Dean, Prof. Matete Bekunda in 2003, the Faculty was leading in Academic programmes, significant financial research funds, several publications, and staff with PhD as well as MSc.”
Administrative roles
Administratively, Prof. Sabiiti held several leadership positions spanning a period of nine years, 1993-2003. He served as Head, Department of Crop Sciences, and Dean – Faculty of Agriculture and Forestry (November 1994-2003). Recounting his experience, Prof. Sabiiti said it was during his period as Dean that the Faculty had unprecedented growth in terms of Infrastructural development – the evolution of two Faculties and a Research Institute, and academic programs (under /postgraduate programs). In 1998, the Faculty of Agriculture and Forestry split to two Faculties, Faculty of Agriculture and Faculty of Forestry and Nature Conservation. With NORAD support, a building/home was constructed to house the Faculty of Forestry and Nature Conservation. Kabanyolo University Farm also through a vigorous process was upgraded to Makerere University Agricultural Research Institute Kabanyoro (MUARIK). “With good collaboration with NARO, the Faculty benefited from World Bank funding for five years and the Continuing Agricultural Education Centre (CAEC) was constructed as well as a postgraduate building mainly for girls. Using some innovations, a football field was constructed at MUARIK. With this funding, several staff got further training for Masters and PhD and short courses thus building capacity,” he noted. With savings from overhead costs from research and donor-funded projects, the then faculty was able to purchase for the first time a Leyland bus which is still functional-over 24 years), a small Tata bus, a tractor, a car for the Deputy Dean and restored Fish ponds at MUARIK. The other major purchase was about 100acres of land at Namalyagonja bordering MUARIK land. This was to be used for income generation from crop production, especially growing maize. According to Prof. Sabiiti, the idea behind purchasing more land was to prepare for the future plan to have a College and eventually an Agricultural University.
Other important contributions to the University
Prof. Sabiiti represented the Faculty of Agriculture in Senate. He also Coordinated the SIDA program he had initiated in 1999 to build PhD capacity for staff, improve lab equipment and enhance collaboration with Swedish Universities which was about 2m US$ for 15 years, and the Dryland husbandry Project based in Kazo, about US$850,000. He also served on Boards such NAADS, NEMA UNEB, UISTF /committees–I@Mak, where he had been appointed in his professional capacity. “The SIDA funding is one of my celebrated contributions to the College where we trained in joint collaboration with the Swedish University of Agriculture and produced 9 PhD staff, several MSc staff and also supplemented two staff to finish their PhDs (Drs Katuromunda and Obaa). ”While in Senate, Prof. Sabiiti participated in the formation of the Collegiate system at Makerere University. He also defended the approval for the establishment of the Agrostudies program between CAES and Israel Institute funded by the Israeli Government which has become very popular at Makerere and at other Ugandan Universities. He served as Chair for Professorial Inaugural Lectures for 14 years. He initiated collaboration between the University of Western Sydney, Australia and Makerere University 1995 todate where one PhD from CAES was sponsored by that University and she graduated this year in May 2022. He spearheaded the establishment of the first Makerere University Centre of Excellence in Waste Management at MUARIK which was commissioned by the Swedish Ambassador to Uganda in 2017. It has state-of-the-art equipment for bio-waste research. The Centre was also supported by Edmonton Centre of excellence in Waste management, Edmonton, Canada, Bank of Uganda, Makerere University top management and CAES.

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

With a mission to ensure that agricultural policies are grounded in empirical research and data, APRC is actively investing in capacity-building initiatives that empower researchers, policymakers, and development actors.
In a significant stride toward building climate resilience in African agriculture, APRC recently organized a two-day intensive training workshop focused on the African Agriculture Adaptation Atlas (AAAA) – a state-of-the-art, web-based decision-support platform that facilitates the integration of climate data into agricultural planning and policy.
The workshop, held on Wednesday 25th and Thursday 26th June 2025 at the School of Agricultural Sciences, Makerere University, targeted two key groups: graduate students on the first day, and university faculty, government officials, and development practitioners on the second. This structure ensured tailored learning experiences for both emerging and seasoned professionals, helping to bridge the gap between academic research and real-world policy implementation.
The African Agriculture Adaptation Atlas (AAAA) is designed to provide dynamic, data-rich visualizations that support informed decision-making in agriculture and food systems across the continent. Through interactive maps and analytical tools, users can explore projected climate impacts, evaluate risks, and identify localized, climate-smart adaptation strategies.
Throughout the sessions, participants received hands-on training in a broad range of AAAA functionalities, including:
- Leveraging the Atlas for research and policy communication: Enhancing the ability of scientists and policy actors to translate complex climate data into actionable insights;
- Assessing projected climate impacts and associated agricultural risks: Essential for forward-looking planning and risk mitigation;
- Identifying climate-smart investment options, with a particular focus on the livestock sector, which is especially vulnerable to climate shocks;
- Analysing gendered vulnerabilities: Examining how climate change disproportionately affects women in agricultural communities;
- Understanding the implications of heat stress on agricultural productivity: Supporting targeted interventions to protect producers and their livelihoods;
- Estimating the economic returns of adaptation strategies: Aiding in prioritizing investments and allocating limited resources effectively.
Prof. Bernard Bashaasha, the APRC Coordinator, emphasized the importance of the training in advancing Africa’s adaptation agenda. “As climate change continues to threaten food security and disrupt livelihoods across the continent, tools like the AAAA, and the skills to use them effectively are essential. They empower decision-makers to craft policies that are adaptive, inclusive, and rooted in science,” he noted.
The workshop was coordinated by Dr. Florence Rwiza, Lecturer in the Department of Agribusiness and Natural Resource Economics at CAES.

Specific objectives
- Identify and quantify climate change impacts on tea yield and quality based on historical and newly obtained data and novel data mining methods.
- Screen, select and recommend tea varieties adapted to abiotic (drought and heat) and biotic stresses (diseases and pests).
- Develop new knowledge on the potential of local waste biomass (tea prunings, banana pseudostems and peels) as soil amendments- mulch, compost, biochar, to recycle nutrients, improve soil fertility, increase carbon sequestration and alleviate drought.
- Reveal NbS through agroforestry combined with organic mulch, irrigation and resilient tea varieties that increase biodiversity and tea yield.
- Innovate new methods to enhance tea production under climate change through rainwater harvest and climate-smart irrigation infrastructure.
- Empower vulnerable groups (women, youth, and people with disabilities) in tea production and processing to ensure multi-actor involvement and socio-economic benefit outreach of the proposed NbS in tea cultivation and production.
- Identify export market strategies for NbS tea products, aligned with consumer preferences.
