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.

During the afternoon of September 21, 2026, Makerere University played host to regional discussions as students, academics, and government officials gathered to commemorate the International Day of Peace under the theme “Investing in Regional Peace and Trade for Shared Prosperity”.
The event organised by the Makerere University 92nd Guild Security Ministry in partnership with the Global Peace Guild, served as the official launch of the East African Peace and Trade Law Moot Court Competition. The idea was conceived as an annual event where the youth across East Africa will gather to deliberate on the nexus between regional peace and trade in fostering regional integration.
Acting Vice Chancellor (VC) of Makerere University Prof. Anthony Muwagga Mugagga graced the event, welcomed the distinguished guests and set a reflective tone for the day.
Reminiscing about his old days the VC noted, “lecturers were the ones who used to come and talk about politics, economics, and law but somehow, somewhere, things never went well”. He appreciated the Students’ Guild, and all who were involved in organising the celebration and launch for a good job done.
Prof. Mugagga further encouraged students to look beyond the classroom, urging them to engage in critical debates in different sectors while emphasising that peace is a prerequisite for all development.
People anchor Trade – Keynote address
Representing the guest of honor who was the Minister of State for East African Community Affairs Hon. James Magode Ikuya, Dr. Andrew Musiime – Commissioner for Political Affairs, delivered a keynote address.
His entry was that you cannot talk about trade and not talk about people. Trade is done by people, and therefore as a Ministry, they facilitate free movement of people.
Dr. Musiime provided a comprehensive breakdown of the East African Community (EAC) as an intergovernmental organisation.
“So it is an intergovernmental organisation. Therefore, the governments remain with their constitution, the governments remain with their sovereignty, the governments remain with their national boundaries, the governments remain with their national laws, Musiime explained.”
He mentioned that the East African Community is anchored on the four pillars for integration that is the Customs Union, the Common Market, the Political Federation and Monetary Union.
Dr. Musiime equally challenged the students to move beyond theory, urging them to research the EAC treaty and actively participate in regional integration.
In a gesture of togetherness, he told the distinguished guests that the Ministry operates an open door policy for students and those interested in engaging can apply for opportunities across the Ministry’s various departments.
From UPE to the Halls of Parliament
The event also featured inspiring remarks from the National Female Youth Member of Parliament, Hon. Mercy Kanyesigye. Reflecting on her own journey from Universal Primary Education (UPE) to the halls of Parliament, she delivered a powerful message on peace and security.
In agreement with Prof. Muggaga, she linked the day’s theme to the practical realities of trade, noting that sustainable trade can not exist without peace.
“This moot competition is therefore not just academic exercise. It’s a training ground for the next generation of East African traders, lawyers, negotiators, judges, policy makers who will defend the spirit of our East African common market and our custom union”, Kanyesigye told the attendees.
92nd Guild Calls for Embracing Dialogue
Hon. Denis Mabirizi, the Minister of Security for the Makerere University 92nd Guild, underscored the event’s purpose by highlighting that peace is the foundation for justice, opportunity, and cooperation. He then called upon the student community to reject violence and intolerance, urging them to use dialogue and established leadership structures to address their concerns.
Mabirizi also emphasized that universities are not just centers of academic excellence, but places where the leaders of tomorrow are shaped.
“Universities are not only centers of academic excellence, they are also places where future leaders are shaped. The conversations we have, the values we promote, and the decisions we make today will influence the kind of society we create tomorrow. Peace begins with each one of us, Mabirizi noted.”
The Global Peace Guild Initiative
Mr. Joseph Micheal Tenywa, the founder and President of the Global Peace Guild, shared the vision behind the organization. He explained that the Global Peace Guild was born out of a desire to involve young people in the promotion of peace, trade, and regional integration.
“Global Peace Guild is an initiative born out of a desire to have young people get involved into the promotion of peace, trade, and regional integration.”
He reminded the audience that regional integration would only become a reality when young people actively participate in the market and hold policy makers accountable.
“As we commemorate the International Day of Peace, it’s an invitation for young people to get involved, not only in ensuring that there is no violence, but that we also put in place the conditions that take our strength, and these are our economic provisions, we call it trade.”
The launch of the East African Peace and Trade Law Moot Court Competition marks a significant milestone for the student community as it brings together academic rigor with a focus on regional policy.
International Day of Peace is observed globally on September 21, 2026, under the unified United Nations theme: “Invest in Peace – For Everyone, Everywhere, Every Day”. The day emphasizes that achieving lasting peace requires continuous local action, shared civic responsibility, and strategic conflict mitigation to ensure long-term regional development.
Makerere University has urged female students admitted under the Makerere University Council Tuition and Functional Fees Waiver Scholarship for the 2026/27 academic year to take the opportunity seriously, focus on their academic performance, and stay alert about their personal safety.
The message was delivered during an orientation for the scholarship beneficiaries at the Senate Conference Hall, where officials from the Gender Mainstreaming Directorate welcomed the students and shared guidance on academic success, security, mentorship, and responsible social conduct.
The Chief Gender Mainstreaming Officer cautions students on safety and self-reliance
Dr. Euzobia Mugisha Baine, Chief Gender Mainstreaming Officer, congratulated the students on receiving the scholarship and urged them not to take it for granted.
She advised them to seek information from the relevant university offices instead of relying on assumptions or what fellow students tell them, and to keep records of official communication whenever they raise concerns or follow up on university matters.
Dr. Baine said students should take responsibility for their own security, warning them not to trust strangers easily and urging them to be careful about where they go and who they interact with.
She also reminded them that strong academic performance is required to keep the scholarship, and encouraged them to ask for help early whenever they face academic, social, or other challenges instead of waiting until the situation becomes harder to manage.
Students urged to aim for first-class results
The officers welcomed the students and encouraged them to put their studies first, urging them to aim for first-class academic results during their time at Makerere.
They advised them to use the academic support available to them, including help from course mates and any tutorials or mentoring offered within their colleges, and not to hesitate to seek assistance when they have concerns about their results or coursework.
The GMD team also spoke to scholars about personal safety, cautioning students against accepting help from strangers, including with luggage or transport, and referred to a recent incident in which a student’s belongings were stolen. She urged them to stay alert as they settled into university life.
Focus on academic foundations and safe social conduct
Other speakers, including Ms. Susan Mbabazi, who is the Principal Gender Officer, Ms. Abilat Lozirah, and Cynthia Ayaa Kamaketch emphasised the need to build a strong academic foundation from the start of the semester. They encouraged students to attend lectures regularly, read beyond classroom notes, use university resources such as internet access and the library, and develop steady study habits instead of waiting until exams are near.
They also warned students to be careful when meeting people they do not know well, advising them to hold academic discussions and social meetings in open, public spaces such as Freedom Square rather than in private rooms.
The students were also encouraged to seek mentorship from university staff and others who could guide them in their academic and career development, and to identify a mentor before leaving the orientation.
The orientation also pointed students to key university services and locations they should know, including the university health facilities, the Makerere Police Post, the Counselling and Guidance Centre, and places of worship on campus.
Speakers reminded the students that the scholarship gives them a chance to pursue their education at Makerere University, and that keeping it depends on their discipline, academic performance, and willingness to seek support when needed.
