Whereas River Nyamwamba in Western Uganda is well known for the destruction of property and loss of life whenever it overflows, the environmental effects are less known and could be more lethal
The mining and processing of copper in Kilembe, Western Uganda, from 1956 to 1982 left over 15Metric Tonnes of tailings containing cupriferous and cobaltiferous pyrite dumped within a mountain river valley. In addition, underground Kilembe mine water is pumped to the land surface or allowed to flow by gravity into surrounding agricultural soils and water bodies. The study was conducted in Kilembe mine, Kasese district to assess the impact of Kilembe mine and the wastes (tailings) on soil quality, water quality, foods frown, forage and local people exposure. The samples collected included soil, water, foods, forage, sediments and toe nails from local volunteers.
Sample analysis was conducted from the school of biosciences, Nottingham University, UK. The study found high levels of metal concentration especially copper, cobalt, nickel, zinc, arsenic and lead in agricultural soils, public water sources, house dusts and sediments in water. Aluminium and Iron metals were more abundant in public water sources. The metals were not only originating from mine tailings but also underground Kilembe mine water. The leachate water at Kilembe mine also contain large amounts of metals especially copper, iron and aluminium.
The foods and forage grown contained significantly higher concentrations of copper, cobalt, zinc, possibly taken up during growth and accumulated in the foods which could lead to consumption of the same elements by local people. Indeed, tests on human toe nails from Kilembe area volunteers confirmed that local people were more exposed to the mine metals especially copper, cobalt and nickel. Children were more exposed than adults.
It is on this note that the following policy recommendations are made;
1. There is need for enforcement of proper waste storage and disposal protocols 2. Local people living in contaminated environments should be sensitized on the dangers so that they make informed decisions 3. There is need for construction of a containment all around Kilembe tailing sites and land filling with soil so as to prevent erosion of tailings into agricultural soils and water 4. There is urgent need to treat Kilembe mine underground water before it is discharged into River Nyamwamba 5. There is need to implement remediation activities for soils along River Nyamwamba and below tailings
Summary of findings
Water quality Over 25 % of domestic water samples collected and 40% of River Nyamwamba waters along the mine area and downstream exhibited Cobalt concentrations exceeding the Wisconsin (USA) drinking water thresholds of 40 μgL-1. Almost all water samples upstream of River Nyamwamba exceeded UK recommended Iron and Aluminium concentrations in drinking water. Most domestic water samples (67%) exceeded recommended drinking water thresholds for Aluminium, Iron and Cobalt.
Forage Elevated concentrations of Iron, Cobalt, Copper, Zinc and Lead were found in forage grasses collected along the mine area and downstream. The high levels of metal in forage could affect the health of animals and will also be reflected in the milk and beef produced in Kilembe area exposing consumers to metals.
Human exposure Trace elements concentrations (mg kg-1 dw) were found in toe nails of 15 adults and 12 children from the Kilembe copper mining district in Western Uganda. Control samples were from 5 children aged 9-14 years and 5 adults aged 20-60years. The toe nails clearly confirmed exposure of the local people with children being more exposed and affected than adults.

Makerere University has intensified efforts to strengthen research governance and ethical oversight, with university leaders calling for greater institutional support for Research Ethics Committees (RECs), whose role has become increasingly central to the institution’s research-led agenda.
The call was made during a high-level meeting between University Management and Chairpersons of Research Ethics Committees held at the Vice Chancellor’s Boardroom at the Makerere University Main Building on May 25, 2026.
Opening the meeting, the Director of Research Innovations and Partnerships (DRIP), Prof. Robert Wamala, highlighted a number of operational and administrative challenges affecting the effectiveness of RECs at Makerere University.
Prof. Wamala observed that RECs continue to operate with gaps in institutional framework outlining their position within the university governance structure, a gap he said has affected institutional support and long-term sustainability.
According to Prof. Wamala, inadequate facilitation continues to affect the operations of several committees, especially in areas of staffing, administrative coordination, and remuneration for REC administrators.

He also pointed to challenges arising from new regulatory requirements governing the appointment of REC members, particularly the need for appointment letters to be authorized or signed by the Vice Chancellor.
Prof. Wamala further raised concern over the high cost of mandatory accreditation and training processes required by the Uganda National Council for Science and Technology (UNCST), especially the Good Research Regulatory Practice (GRRP) training undertaken every three years. “Payment for training is too high for individual RECs to cover,” he noted, adding that many committees are struggling to independently raise the money to undertake the training for all their members.
He also emphasized the need for stronger institutional monitoring systems to support timely submission of accreditation renewal applications, oversight of approved research activities, and coordination of REC operations across the university.
In her remarks, the Deputy Vice Chancellor in charge of Academic Affairs, Prof. Sarah Ssali, commended the growing contribution of RECs in advancing Makerere University’s research agenda and acknowledged the concerns raised by Prof. Wamala and committee members.
“There were not very many RECs,” Prof. Ssali said. “So now that we are 10, it is really impressive because it speaks to our cause for a research-led university.” She admitted that despite their importance, many RECs still operate outside the formal university establishment, making staffing and operational support difficult.

“The only challenge that I see is that they are not fully institutionalized. So it is upon units to start them or not to start them,” she explained. Prof. Ssali added that because RECs are not fully integrated into the public service structure of the university, recruiting and remunerating staff through conventional university systems remains complicated. “Hiring for them staff will be a little bit cumbersome because the university will say they are not part of our structure,” she said.
She nevertheless emphasized that university management recognizes the strategic importance of RECs in strengthening ethical research oversight and supporting Makerere’s position as a research-led institution. “RECs are doing a great job of furthering our strategic agenda of being a research-led university,” she noted.
Prof. Ssali explained that the growing reliance on institutional RECs by the Uganda National Council for Science and Technology demonstrates the trust placed in Makerere University’s ethical review systems.
Addressing concerns about the cost and frequency of mandatory training, Prof. Ssali acknowledged the financial burden on RECs but explained that many of the requirements are set by national regulators. “Many of the things you have raised are with National Council, they are not with us,” she said. “We can only pledge to lobby.”
To address logistical challenges associated with training senior academics, she proposed more flexible scheduling arrangements. “For a professor to give you a whole day is going to be a challenge,” she said. “Maybe you can do half days throughout the week.”
Prof. Ssali also encouraged colleges and schools to allocate part of their enhanced research budgets toward supporting REC activities, including staffing, training, and operational facilitation.

She suggested that colleges and schools hosting RECs should directly take responsibility for sustaining them. “For me, that’s the way out — to ensure that the colleges and schools that have RECs take them as their responsibility,” she noted.
The DVC-AA also addressed concerns related to intellectual property rights, Material Transfer Agreements (MTA), and the need for researchers to formally communicate scientific discoveries and innovations to the university to ensure institutional protection and benefit-sharing. “All you are saying is true, but it depends on you as researchers informing the institution that we have made this discovery,” she said.
Prof. Ssali reiterated Makerere University’s commitment to strengthening research governance systems and pledged continued engagement with both university management and national regulatory bodies to address the concerns raised by REC members. “Where they are, they enable research, publication and growth,” she said of the RECs. “Most importantly, they enable us to be ethical with the way we do our things.”
The meeting was attended by chairpersons of the various Research Ethics Committees across Makerere University and affiliated institutions. These included Dr. Ponsiano Ochama from the School of Medicine Research Ethics Committee (SOM-REC), Dr. Moses Ocan from the School of Biomedical Sciences Research Ethics Committee (SBS-REC), Dr. Paul Kutyabami from the School of Health Sciences Research Ethics Committee, Dr. David Kyaddondo from the Uganda Cancer Institute Research Ethics Committee, Dr. Stella Neema from the School of Social Sciences Research Ethics Committee (MAKSS-REC), Dr. Joseph Kagayi from the School of Public Health Research Ethics Committee, Dr. Joseph Kateete from the Infectious Diseases Institute Research Ethics Committee, Dr. Fred Okuku from the Uganda Heart Institute Research Ethics Committee, Dr. Kassim Sadik from the College of Agricultural and Environmental Sciences Research Ethics Committee, and Dr. Eddy Walakira from the College of Business and Management Sciences Research Ethics Committee.
The discussions reflected Makerere University’s broader ambition to consolidate its position as a leading research-intensive institution while ensuring that ethical standards, accountability, and innovation protection remain central to its academic mission.
On May 29, 2026, the Mastercard Foundation Scholars Community learned of the passing of Sylas Ruhweza Atwooki, a remarkable Scholar of the Mastercard Foundation Scholars Program at Makerere University. At just 32 years old, Sylas had already made an indelible mark. He served as the representative of Makerere University on the Mastercard Foundation Advisory Board, contributing to vital decisions that shape the future. Additionally, he held the prestigious role of Minister of Information for Tooro Kingdom, an extraordinary achievement that set a powerful example for his peers and illuminated the potential for leadership and impact within the community.
Sylas was born on 19 July 1994 to the late Tinkasimire Paul Adyeeri and Ms. Ategeka Margret Abwooli in what is now Bunyangabu District. As the ninth of eleven children, he recognised early the power of education and the doors it can open. His academic journey commenced at Kaboyo Primary School, followed by Fort Portal Secondary School for his O-levels. With the backing of the Mastercard Foundation Scholarship, he confidently pursued his A-levels at Hannah International School and later enrolled at Makerere University, where he successfully earned a Bachelor of Science in Petroleum Geoscience and Production in 2022, once again bolstered by the Mastercard Foundation Scholars Program.
Sylas actively contributed to the Scholars community as the 3rd President of the Scholars Association Makerere University (SAMAK) and as the first Team Lead of the AlumNet Foundation, established in 2018, an umbrella organisation that unites all the alumni of the Mastercard Foundation at Makerere University. This organisation serves as a community of practice for Makerere University alumni, promoting agency and voice, peer mentorship, and community-impact initiatives. He demonstrated transformative leadership as Chairperson of the Mastercard Foundation Alumni Network at BRAC from 2020 to 2022. At the time of his death, Sylas served as the Minister of Information in the Tooro Kingdom and as the Strategy and Engagement Lead for the Mastercard Foundation Alumni Network’s Uganda Chapter, where he continued to advocate for collaboration and social responsibility. He was a Programme Associate at Africa Climate Collaborative, one of the Mastercard Foundation Initiatives at Makerere University, and was also pursuing his Master’s degree at Victoria University. May his soul find eternal peace.
