Professorial Inaugural Lecture Unlocks the Wealth of Environmental Science
The field of Environmental Science plays a very important and yet not often talked about role in society today. For example, did you know that Lake Nabugabo is scientifically considered very safe for recreation by WHO, US-EPA (World Health Organisation, United States-Environmental Protection Agency) standards owing to its natural inability to sustain snails; the intermediate hosts for bilharzia? Thanks to research by Environmental Scientist; Prof. James Okot-Okumu, we have access to such information, as well as more worrying trends. This world Ramsar Site could easily be destroyed within the next ten years unless the rapid development of recreation centres along its banks is regulated.
However, did you know that one of nature’s own Phytolacca Dodecandra also locally known as Luwooko in Central Uganda produces chemicals that can kill fresh water snails; the intermediary hosts of bilharzia? Research by other Environmental Scientists in Ethiopia has gone on to prove that Phytolacca Dodecandra is best stored in powder and not in seed form for maximum potency. All this and more came to light as Prof. Okot-Okumu delivered the Professorial Inaugural Lecture before friends, family and students in the Main Hall, Makerere University on 25th October 2019.
Congratulating Prof. Okot-Okumu upon reaching his milestone, the Acting Vice Chancellor and Deputy Vice Chancellor (Academic Affairs), Dr. Umar Kakumba noted that Professorial Inaugural Lectures mark the apex of the scholarly journey of University academics the world over.
“Professors are appointed to this rank following a scholarly journey of searching for new knowledge in their areas of expertise. It is therefore important that they should make this information accessible to the public, by way of contribution to society” added Dr. Kakumba.
The Acting Vice Chancellor also paid tribute to the College of Agricultural and Environmental Sciences (CAES), and the Department of Environmental Management; the academic home of Prof. James Okot-Okumu in particular, for its contributions to research, and added “your outgoing Department Chair is both challenging and inspiring you today.”
Earlier on, the Chairperson of the Professorial Inaugural Lectures Organising Committee, Prof. Elly Sabiiti had introduced the theme of the Lecture; “Evolution of Environmental Science: The Science of Integration”. He shared that this was an important subject concerned with the relationship between the environment, man and society, which is more relevant today as the world contends with the effects of climate change.
Prof. Sabiiti noted that although Professorial Inaugural Lectures are meant to be given following appointment to the rank, Professors may present them at different points in their career.
“I therefore wish to take this opportunity to encourage both recently appointed and the longstanding Professors to make use of this unique opportunity to showcase their expertise as intellectuals, by demonstrating the value and worth of being Professor” urged Prof. Sabiiti.
It was a moment of pride for CAES as the Principal Prof. Bernard Bashaasha took to the podium to read the citation in honour of Prof. James Okot-Okumu.
“This afternoon as it is in the tradition of this great university; Makerere University, we have a presentation of the Professorial Inaugural Lecture that follows the conferring of the rank of full professor on an academic by the university. This is a tradition that has been practiced by universities the world over, to celebrate the professional achievements, scholarship and the contributions of a Professor to the university, social and economic development of the nation” beamed Prof. Bashaasha.
Prof. Bashaasha shared that Prof. Okot-Okumu joined Makerere University as a Lecturer in 1990 and gradually grew through the ranks of Senior Lecturer, Associate Professor to full Professor. Since then, he has taught courses such as: Water Resources Management, Cleaner Production, Solid Waste Management, Pollution Analysis, Environmental and Social Impact Assessment (ESIA) and Environmental Audit.
Prof. Okot-Okumu has conducted research on water quality, water pollution and solid waste management and shared his findings through publications in scientific journals and book chapters. He has also supervised graduate students of Environmental Science and Natural Resources at Makerere University as well as students of Waste Management at Wageningen University in the Netherlands and Kenyatta University, Kenya.
Before delving into his presentation, Prof. James Okot-Okumu paid tribute to his wife; Mrs. Judith Achen Okot, his children, other members of the family present and colleagues. The family man could not hide his love and appreciation for his family, whose support had seen him scale the academic ladder. He equally thanked his colleagues for the encouragement and mentorship over the years.
It was clear from the presentation that Prof. Okot-Okumu takes great inspiration from quotes. Right from Ernest Haeckel (1834-1919) who coined the term ecology, to George Washington Carver (1865-1943) who introduced modern day farming in the USA, the Professorial Inaugural Lecture deliverer took the audience on a journey of appreciating science in the context of history its contribution to current body of knowledge.
For example, Prof. Okot-Okumu shared that Forest Rivers near Kampala City specifically in Mabira, Kitubulu, Zika and Mpanga have historically apart from sustaining the forest hydrology, also carried along water with nutrients and other materials obtained from the forests that feed the downstream ecosystems. This, he noted, is however being threatened by the continued encroachment on these forests as human activity increases.
“With the rapid degradation of these forests mainly from illegal felling of trees, the evapotranspiration and infiltration components of the hydrological cycle are reduced while runoff water losses are increased in these locations within the Lake Victoria basin and are putting stress on environmental maintenance requirements of the rivers” warned Prof. Okot-Okumu.
He also made reference to the increasing cost of piped water supplied by the National Water and Sewerage Corporation as another effect of human and industrial activity polluting the Murchison bay of Lake Victoria.
“Water treatment at this utility is now gradually replacing Aluminium sulphate with synthetic polymers as coagulant at an added cost to consumers. There is therefore need to think about innovative cheaper way to treat water especially for the sector of the community who cannot afford the current costs of water” he explained.
Thankfully, Prof. Okot-Okumu and fellow researchers in 2015 conducted research on the use of alternative solutions readily available in nature to treat water.
“Having seen drawbacks in some of the conventional methods, we have tested some readily available plant materials that required simple preparation methods and were cheap to use. These are seed powders from Java plum, Jackfruit and Moringa that worked very well as coagulates to clarify water from community wells” shared Prof. Okot-Okumu.
He added that the same seed powders, when used in certain concentrations were able to remove turbidity (matter suspended in water) by more than 95% as well as the bacterial effects of agents like E. coli, P. aeruginosa, S. Typhii, S .dysenteriae, S. aureus and S. faecalis within the range of 98 -100% hence making the water safe for drinking.
As the urban centres continue to expand, increasing amounts of solid waste are being generated and poorly disposed of in the environment. Prof. Okot-Okumu therefore advocated for the application of approaches of Integrated Solid Waste Management (ISWM), which he said would help prolong the lifespans of landfills such as Kiteezi owned by the Kampala Capital City Authority (KCCA).
“Applying approaches of ISWM such as Cleaner Production (CP), Lean Production (LP), Industrial Ecology (EC), Circular Economy (CE) and Sustainable Consumption and Production (SCP) that are Green Development Strategies can mitigate the impacts of solid wastes” advised Prof. Okot-Okumu.
He proposed that science needs to copy more from nature whereby the waste from one organism or system becomes a raw material or input for another. This, he further shared, would create a very efficient system for sustainability and mitigate damage to the environment caused by poorly disposed of solid waste.
Whereas Prof. Okot-Okumu admitted that Makerere University through the Department of Environmental Management (DEM) plays a leading role in training the best Environmental Science graduates in Uganda, he his concluded his Professorial Inaugural Lecture with a call to action.
“The university can still do better by allowing the training programs at DEM to evolve together with the national and global challenges of environmental management. By working in collaboration with other Departments in Science and Social Sciences at the university, DEM can improve on the training and research in environmental science to support Uganda’s sustainable development efforts” Prof. Okot-Okumu concluded.

Kampala, September 4, 2026 — Makerere University and the Japan International Cooperation Agency (JICA) have explored new opportunities for strengthening academic, research and innovation collaboration between Uganda, Japan and other African countries, with a particular focus on artificial intelligence (AI), aerospace engineering, materials and remote sensing, food value chains, energy, water and climate change.
The discussions took place on Friday, September 4, 2026, at the Makerere University Main Building in the Vice Chancellor’s Board Room, during a visit by a JICA delegation led by Dr. Okano Takasei, Senior Advisor, Human Development Department of JICA.
Makerere keen to deepen collaboration with JICA
Welcoming the delegation, the Deputy Vice Chancellor (Academic Affairs), Prof. Sarah Ssali, highlighted Makerere University’s long-standing tradition of research, international collaboration and contribution to knowledge generation in Uganda and beyond.
Prof. Ssali noted that Makerere has built a strong global research footprint through partnerships with institutions around the world, observing that the University is well positioned to deepen international collaboration as emerging technologies, particularly artificial intelligence, continue to transform research and higher education.
“Uganda has a very long history of doing research, and particularly it has informed research findings in the areas global health research,” Prof. Ssali said, pointing to Uganda’s historical contribution to global scientific knowledge.
She cited the country’s contribution to medical and biological research, including early research on sleeping sickness, noting that Uganda’s unique research environment continues to offer opportunities for scientific discovery.
Prof. Ssali said Makerere’s history of collaboration with Japan is particularly significant, noting that Japanese cooperation has contributed not only to academic and research activities but also to infrastructure development and other sectors in Uganda.
She cited the establishment of the JICA building at Makerere, describing it as one of the visible symbols of Japan’s long-standing partnership with Makerere University.
According to Prof. Ssali, the building, which houses College of Natural Sciences (CoNAS) disciplines of geology, petroleum studies and administrative offices, was constructed during her undergraduate years and completed within a remarkably short period.
Prof. Ssali said the long-standing relationship between Uganda, Makerere University and Japan provides a strong foundation upon which new areas of collaboration can be built. She encouraged the visiting JICA delegation to explore the University and identify areas where existing partnerships could be strengthened or new areas of cooperation developed.
“Please take time and explore and see where either you already have a footprint, where you’ve ever had a footprint, or where you could explore new areas,” she said.
Prof. Ssali added that Makerere was privileged to host the JICA delegation and expressed optimism that the visit would lead to meaningful and sustainable partnerships.
Strengthening Joint Collaboration through AJ-ASPIRE
Dr. Okano, in his remarks as leader of the delegation said the visit formed part of a broader JICA initiative aimed at promoting academic and research collaboration between Japanese and African universities.
He explained that the initiative was launched on the occasion of the ninth Tokyo International Conference on African Development (TICAD 9), held in Yokohama in September 2025, with the objective of strengthening academic and research partnerships between Japan and Africa.
According to Dr. Okano, the initiative is intended to benefit both African and Japanese universities by providing platforms for internationalisation, collaborative research and the exchange of knowledge, researchers and students. “We would like to play a role of facilitator between universities in Japan and Africa and Uganda as well,” he said.
He explained that JICA is currently promoting the initiative through three African hub universities where JICA already has ongoing projects and experts on the ground.
The three institutions are Egypt-Japan University of Science and Technology (E-JUST) in Egypt, Jomo Kenyatta University of Agriculture and Technology (JKUAT) in Kenya, and Stellenbosch University in South Africa.
Dr. Okano said the selection of the three institutions was informed by the presence of ongoing JICA-supported projects and experts who can facilitate collaboration between the hub universities and institutions across Africa and Japan.
The hub universities are currently coordinating research with Japanese universities in strategic areas, with E-JUST focusing on energy, JKUAT leading work on food value chains, and Stellenbosch University focusing on water and climate change.
Dr. Okano said JICA was particularly pleased to explore collaboration with Makerere University under the African-Japan Initiative for Research and Education Partnerships, known as AJ-ASPIRE.
He outlined three major avenues through which Makerere could participate in the initiative.
The first is participation in existing research programmes hosted by the three hub universities. He added that Makerere researchers could join ongoing research on energy, food value chains, water and climate change, thereby creating opportunities to work with Japanese and other African researchers.
“We would like to explore opportunity for researchers from Makerere University to participate in these ongoing research activities and expand collaboration with Japanese and African partner institutions,” Dr. Okano said.
The second area is the development of new research networks in artificial intelligence and aerospace engineering. Dr. Okano said JICA was planning to establish new research groups focusing on the two areas and would be interested in having Makerere researchers participate in the emerging networks. “We would like to also invite researchers from Makerere University to join these networks and implementation of future collaboration in these two research topics, aerospace engineering and AI,” he said.
The third proposed avenue is increased collaboration between Makerere University and E-JUST, which Dr. Okano said offers fully funded scholarship opportunities for African students through a programme jointly supported by the governments of Egypt and Japan.
He noted that a number of Makerere graduates have already benefited from the programme, including researchers who have pursued doctoral studies and research opportunities in Egypt and Japan.
Dr. Okano cited the example of Mr. Abdonoor Kalibala, a Makerere alumnus whom he recently met in Hiroshima, Japan, following completion of PhD in Mechatronics and Robotics engineering at E-JUST. Mr. Kalibala conducted research in Japan for up to six months under the supervision of a Japanese professor as part of his doctoral programme.
Dr. Okano said such programmes could help strengthen the movement of researchers between Uganda, Egypt and Japan and create lasting institutional partnerships.
He added that JICA is also providing small research grants to alumni of the programmes to help them maintain and expand research collaboration involving Japan, E-JUST and African institutions.
He said Makerere could leverage such opportunities to increase the participation of its students and researchers in international research networks.
AI, Materials and Remote Sensing and International Relations Set the Pace
Prof. Robert Wamala, Director of Research, Innovations and Partnerships at Makerere University, said the visit followed an online engagement held a few weeks earlier between Makerere University and JICA, during which several areas and units within the University were identified as potential points of collaboration.
Prof. Wamala said these included the Makerere University AI Lab, the University’s International Office and researchers working in space engineering, particularly in materials and remote sensing.
He welcomed the transition from online discussions to physical engagement, saying the visit would allow JICA representatives to interact directly with researchers, academic units and University authorities. “This interest is being followed up through an in-person visit, which provides us an opportunity for JICA to engage directly with the relevant units and researchers at Makerere University,” Prof. Wamala said.
For Makerere, he added, the initiative provides an opportunity to connect the University’s research strengths with Japanese universities, research institutions and development partners to address shared development challenges.
Prof. Wamala said the University was particularly interested in identifying practical areas of collaboration that could move beyond general discussions to concrete research partnerships, joint projects and opportunities for students and researchers.
He noted that the JICA delegation’s on-campus interactions scheduled to take place throughout the day would enable the two sides to identify specific areas of mutual interest. “We hope these engagements will help us identify specific areas of future interest and provide a basis for developing concrete areas of collaboration under the AJ-ASPIRE,” Prof. Wamala said.
He reiterated Makerere’s commitment to strengthening international research partnerships and thanked JICA for its continued interest in the University.
Dr. Okano, was accompanied by Mr. Ito Idomu, Research and Advisor at the Embassy of Japan, Mr. Osaki Mistuhiro from JICA headquarters, Ms. Eric Maeda from JICA Headquarters, and Ms. Ruth Mbabazi from JICA Uganda.
JICA follow-up meetings with Makerere research units
Following the high-level meeting in the Vice Chancellor’s Board Room, the JICA team, together with the Directorate of Research, Innovations and Partnerships, proceeded to engage with key research and administrative units at Makerere University identified as strategic to the proposed areas of collaboration.
The delegation held meetings with the Makerere University AI Lab, led by Dr. Joyce Nabende of the College of Computing and Information Sciences (COCIS), to explore opportunities for cooperation in artificial intelligence and related emerging technologies.
The team also met officials from the Makerere University International Office, led by Mr. Mathias Ssemanda, where discussions focused on opportunities for strengthening international academic linkages, mobility and institutional partnerships.
A further engagement was held with the Department of Geomatics and Land Management, focusing on materials and remote sensing, led by Prof. Lydia Kayondo from the College of Engineering, Design, Art and Technology (CEDAT).
The engagements provided an opportunity for the JICA team and Makerere researchers to move from broad discussions on collaboration to more specific conversations around research interests, expertise, existing projects and potential areas for joint work.
The visit marks an important step towards strengthening Makerere University’s engagement with Japanese and African research institutions under AJ-ASPIRE, while opening opportunities for researchers and students to participate in emerging international networks in artificial intelligence, aerospace engineering, remote sensing and other strategic areas of science, technology and innovation.
