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 challenged newly admitted postgraduate diploma and master’s students to take ownership of their academic journey, produce knowledge that addresses Africa’s challenges and use their training to create opportunities for society.
The call was made on Tuesday, August 11, 2026, during the orientation of postgraduate diploma and master’s students held at the Main Hall, Main Building, Makerere University. The orientation was conducted under the theme “Harnessing the Power of Graduate Training to Transform Africa’s Research Trajectory.”
Addressing the students, Prof. Sarah Ssali, Deputy Vice Chancellor for Academic Affairs, said admission to postgraduate education marked an important transition from undergraduate study and should come with greater independence, critical thinking and responsibility.
“Postgraduate study is not just the accumulation of knowledge. You are now active researchers, critical thinkers and creators of your own knowledge,” Prof. Ssali said.
She said postgraduate training should enable students to deepen their expertise, strengthen their analytical abilities and develop solutions to real-world problems.
Prof. Sarah Ssali.
“Through your projects, dissertations, innovations and professional practice, you have the opportunity to contribute knowledge that can influence policies, improve services and transform lives. Your research matters, and your contribution matters,” she said.
Prof. Ssali urged students to see their studies beyond the pursuit of a degree, encouraging them to ask themselves why they had chosen postgraduate education and what contribution they intended to make to their communities and professions.
“See your coursework as an opportunity to develop knowledge and skills that will help you propose new solutions to real-world challenges,” she said.
She also encouraged students to embrace collaboration with communities and non-academic partners, saying many of them were already coming to the University with professional and community experiences that could enrich their research.
“Don’t think that your scholarship is only for those who look academic. Embrace community, embrace networks,” she said.
Prof. Ssali further cautioned the students against wasting time, noting that many postgraduate students have employment, family and other responsibilities alongside their studies.
“Make the most of your time and don’t waste it,” she said, urging students to use available study time productively even when there are changes in their lecture schedules.
She also emphasised the need for students to take responsibility for their progress instead of waiting for lecturers or supervisors to push them.
“Postgraduate education requires independence, independent inquiry, independent research, independent interrogation and also active participation,” Prof. Ssali said.
Prof. Julius Kikooma, Director of Graduate Training, told the students that their admission was a significant achievement given the large number of applicants seeking postgraduate opportunities at Makerere.
“We received over 12,000 applications to our postgraduate programmes, but we are only able to take just a small percentage of that. That means you are just the few people who are able to do this,” Prof. Kikooma said.
He urged the new students to appreciate the opportunity and understand that graduate education carries responsibilities beyond attending lectures and completing examinations.
According to Prof. Kikooma, Uganda and Africa require highly trained human capital capable of driving national and continental development priorities.
“The country needs more highly trained people if it is going to achieve its aspirations and priorities for national development,” he said.
Prof. Julius Kikooma.
He challenged the students to consider what Uganda and Africa would look like in the coming decades and to question whether the continent would continue relying on ideas, innovations and creations generated elsewhere.
“Will it still be a country that always depends on ideas, innovations and creations that come from outside?” he asked, before urging the students to become part of the generation that develops home-grown solutions.
Prof. Kikooma said much of what Uganda would need in the future would depend on what the country invests in today, particularly in human capital and research.
He also explained that the Directorate of Graduate Training works with colleges, schools, departments and central University units to strengthen the quality of graduate education.
“We want to make sure that what you are taking away from here is of a certain quality,” he said, adding that the University has established policies, standards and systems intended to create an environment in which postgraduate students can succeed.
However, Prof. Kikooma stressed that the University cannot take responsibility for the entire academic journey on behalf of students.
“We will not replace your programme. We will not replace your lecturers. We will not replace your supervisors. Each of those has a different role to play along your journey,” he said.
He encouraged students to be proactive by understanding their programmes, colleges and the various support services available to them.
“Successful graduates tend to be proactive rather than reactive. So don’t wait until you have a problem, then you start running from it,” Prof. Kikooma said.
He further urged the students to work within the stipulated programme period, noting that most master’s programmes take about two years while postgraduate diploma programmes generally take one year.
Prof. Robert Wamala, Director of Research, Innovations and Partnerships, urged the newly admitted students to use their graduate training to produce knowledge capable of addressing challenges facing their communities, Uganda and Africa.
He challenged them to move beyond consuming knowledge generated elsewhere and instead become producers of knowledge and solutions.

Prof. Wamala emphasised the importance of connecting research to society, innovation and professional practice, encouraging students to identify problems within their workplaces and communities that could become areas for meaningful research.
He said Africa needed researchers capable of generating evidence, innovations and practical solutions to support development rather than simply importing solutions from other parts of the world.
The Director encouraged the students to build collaborative networks during their studies and to regard the University as an ecosystem in which researchers, professionals, communities and other partners can work together.
Dr. Kizito Ongaya, Deputy University Librarian, introduced the students to Makerere’s extensive library and information resources, urging them to make the library a central part of their postgraduate studies.
He said the University Library operates a hybrid system combining physical collections with electronic resources.
“We have over 200,000 types of books in our library, with 45 e-journal databases,” Dr. Ongaya said.
He encouraged students to make use of the University’s electronic databases, noting that substantial resources are invested in providing access to scholarly journals.
L-R: Dr. Mike Barongo, Dr. Kizito Ongaya, Prof. Julius Kikooma and Prof. Sarah Ssali.
“If you don’t use e-journals, you are unacceptable,” he told the students, emphasising that postgraduate research requires extensive engagement with scholarly literature.
Dr. Ongaya also highlighted the University’s archival collections, specialised libraries and information centres located across its colleges.
He said students would be guided on how to access both physical and electronic resources and encouraged them to explore specialised collections that could support their individual research areas.
Dr. Mike Barongo, Team Leader ICT, Department of the Academic Registrar, told the new students that Makerere had increasingly digitised its academic and administrative processes and urged them to complete their online registration as an immediate priority.
He said students could access their provisional admission letters through the online application system and use the student number provided to activate their student portals.
Dr. Mike Barongo.
“The student portal is very, very critical,” Dr. Barongo said.
He explained that students must enrol and register in order to access key University services, including institutional email and Wi-Fi.
“Once you enroll, you create an institutional email address. That institutional email address is the gateway for you to access so many things, like Wi-Fi,” he said.
Dr. Barongo also informed students that ICT support centres were available to assist those experiencing challenges with enrolment, registration or access to digital services.
Mr. George Mugabi Turyamureeba.
He urged students to ensure they enrol and register every semester so that the University systems can accurately capture their academic and financial information.
Others senior members in attendance include the Deputy University Bursar Mr. George Mugabi Turyamureeba and Mr. Henry Nsubuga, the Manager Makerere University Counselling and Guidance Centre.
Makerere University has challenged its newly admitted PhD students to go beyond pursuing academic qualifications and become independent scholars capable of generating knowledge, solving societal problems and contributing to Africa’s transformation.
The call was made by the Deputy Vice Chancellor for Academic Affairs,Prof. Sarah Ssali, during the orientation of the 2026/2027 PhD cohort at Makerere University’s Main Hall in the Main Building on 10th August 2026.
Prof. Ssali told the new scholars that a PhD marks a fundamental shift from previous levels of education, requiring students to take greater responsibility for their academic progress rather than depending entirely on lecturers and supervisors.
“You will have to push yourself and also push your supervisor to move with you,” Prof. Ssali said, urging the students to take ownership of their doctoral journey.
Prof. Sarah Ssali.
She acknowledged that many PhD students have to balance their studies with employment, family responsibilities and community leadership, making doctoral training demanding. However, she urged them to remain focused on completing their programmes within the prescribed three, four or five years.
Prof. Ssali said Makerere expects its doctoral training to produce scholars who can create knowledge, challenge existing ideas and develop solutions to societal problems.
She encouraged the students to embrace ambiguity and become comfortable questioning what they already know, noting that doctoral education requires scholars to identify important questions, investigate them and generate answers that advance knowledge.
The Deputy Vice Chancellor also urged the students to develop interdisciplinary collaborations and scholarly networks rather than confining their research to their individual disciplines.
She said the success of doctoral education should not be measured merely by the number of dissertations completed or papers published, but by the extent to which research contributes to society.

With Africa facing complex challenges, including climate change, disease, population growth and development pressures, Prof. Ssali said PhD scholars have a responsibility to generate evidence that can influence policy, strengthen institutions and advance innovation.
She challenged each scholar to continually ask what problem their research addresses, what solution it advances and whether that solution can create sustainable value.
The Director of Graduate Training,Prof. Julius Kikooma, said the new cohort was joining Makerere at a time when the University is implementing reforms aimed at strengthening graduate education and improving completion rates.
Prof. Kikooma revealed that Makerere received close to 12,000 applications across its master’s, postgraduate and PhD programmes but admitted about 6,000 students.
He said graduate education has been placed at the centre of the University’s efforts to strengthen research capacity and prepare scholars to contribute to knowledge production and innovation.
Under the reforms, PhD students will undertake compulsory cross-cutting courses designed to provide foundational knowledge and skills for doctoral research. They will also be required to undertake teaching in either their second or third year under the guidance of their supervisors.
Prof. Julius Kikooma.
In addition to completing their theses, students will be required to produce at least two publications before graduation, a requirement intended to prepare them to become the next generation of researchers, innovators, inventors and creators.
Makerere has also introduced a digital system to monitor the progress of every PhD student each semester. The system is intended to enable students, supervisors and university officials to identify challenges early and intervene in real time.
Prof. Kikooma urged the scholars to write regularly, think critically, maintain open and constructive relationships with their supervisors and protect their academic integrity and professional reputation.
He also encouraged them to build scholarly networks and remain resilient, noting that rejected papers, disappointing data and unexpected challenges are normal aspects of doctoral training.
The Director of Research, Innovations and Partnerships, Prof. Robert Wamala, challenged the scholars to ensure that the knowledge they produce is trustworthy, responsible and ethically sound.
Prof. Wamala emphasized the importance of respecting the dignity, rights, safety and autonomy of research participants, particularly where studies involve individuals, communities and personal information.
Prof. Robert Wamala.
He highlighted informed consent, privacy, confidentiality, justice and accountability as critical principles of ethical research and urged students to maintain transparency throughout the research process, from developing research questions and collecting data to analyzing and reporting findings.
Prof. Wamala also cautioned the students on the responsible use of artificial intelligence in research.
He said although AI can assist researchers with activities such as language improvement, it does not remove the researcher’s responsibility for the final product.
Researchers, he said, must verify AI-generated information and remain accountable for inaccurate statements, misleading interpretations and incorrect references.
He further urged students involved in international and other research collaborations to establish clear agreements on roles, authorship, data ownership, access and intellectual property before commencing their research.
The Deputy University Librarian, Dr. Kizito Ongaya, meanwhile, urged the new scholars to make full use of Makerere’s library and information resources throughout their doctoral journey.
Dr. Kizito Ongaya.
Dr. Ongaya said the University operates a hybrid library system combining physical and electronic resources, with more than 200,000 books, 45 e-journal databases and over 16,000 archival materials available to researchers.
He encouraged the students to participate in library training to learn how to access and effectively use electronic resources and to explore specialized libraries and information centers across the University’s colleges.
These include resources covering natural sciences, agriculture, veterinary medicine, health sciences, education and humanities, as well as museums, botanical gardens, specialized collections and other research facilities.
