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.

Mastercard Foundation Scholars at Makerere University encouraged to participate in philanthropy work
By Carol Kasujja Adii and Bernard Buteera
Mastercard Foundation Scholars at Makerere University have been encouraged to embrace the spirit of philanthropy as a vital foundation for fostering stronger and more resilient communities. This inspiring call to action took place during the 2025 Community Open Day at the Freedom Square on Saturday, September 6, 2025, where hundreds of Mastercard Scholars, Scholar-alumni, and partners of the Scholars Program gathered to initiate a fundraising drive for the signature Annual Scholars Day of Service.
The Annual Scholars Day of Service stands as a hallmark event through which the Scholars give back to the community in impactful and sustainable ways. During a keynote address titled “How Philanthropy Shapes Resilient Communities,” Prof. Winston Tumps Ireeta, the Deputy Vice Chancellor of Finance and Administration, emphasised that while local philanthropy is not a new concept in Uganda, a more intentional mobilisation of this giving back power is necessary to address broader social challenges.
“Communities that mobilise their own resources—financial, human, and material—are empowered to take ownership of their development. Ownership naturally leads to sustainability, ensuring that solutions emerge from local knowledge, context, and values rather than being imposed from the outside. This approach is essential for effectively tackling our social challenges,” Prof. Ireeta stated.
In his remarks delivered by Prof. Helen Nambalirwa Nkabala, the Principal of the College of Humanities and Social Sciences, Prof. Ireeta highlighted the importance of nurturing the inherent power of local giving. He urged the celebration of current local philanthropic efforts, which can be initiated at the individual, religious, and community levels.
“To foster a culture of giving, we need to create platforms that promote structured, transparent, and impactful contributions,” he argued. “It’s crucial to strengthen our generosity, particularly among the youth, and cultivate a society where giving is valued as a core aspect of leadership and citizenship.”
Prof. Ireeta further noted, “The future of our Communities’ strength lies not in distant promises but in our own hands and collective actions. By fostering local philanthropy, we can build a society that is not only fairer but also more resilient and united.
In his welcoming remarks, Mr. John Osuna, Transition Lead for the Mastercard Foundation Scholars Program at Makerere University, who spoke on behalf of the Program Director, Prof. Justine Namaalwa, expressed gratitude to the Scholars for their collaborative efforts in turning the idea of giving back into reality.
“Let us embody humility, kindness, and compassion through actionable philanthropy. By doing so, we can create lasting impacts, enhancing our reputation as a community that genuinely cares,” Mr. Osuna stated.
The Community Open Day was organised under the inspiring theme: “Nurturing Philanthropy for Resilient Communities,” paving the way for future initiatives that strengthen community bonds through collective generosity.
“We believe that through nurturing philanthropy for resilient communities, our communities shall be able to organise themselves to build resilience beyond what we shall give back,” Mr. Osuna explained.
The vibrant event saw Scholars and Scholar-alumni actively participating by bringing items for auction and buying tickets for the raffle draw as a means of mobilising resources for the construction of a ventilated pit latrine, renovation of two classroom blocks and providing tanks for harvesting clean water for Bwera Primary School in Kabale District.
Speaking at the event, Mrs. Agnes Katumba, the Director of Katumba Estates, one of the long-standing partners of the Scholars Program at Makerere University, tasked the Scholars to embrace the heart of giving back without expecting something in return.
“I thank the Mastercard Foundation; they not only provide scholarships but also give back to the community. I have been able to grow because of them. For scholars, you do not have to wait to be wealthy to give back; every coin counts,” Mrs. Katumba said.
Katumba Estates Ltd contributed three million shillings to the Scholars Give Back project. Another long-standing partner, DFCU Bank, pledged over sh10 million towards the Scholars’ building project.
In her presentation, Ms. Malvin Akwara, a Mastercard Foundation Scholar-alumna, urged current Scholars to contribute to their communities in various ways, including mentorship and guiding young people.
“We are all here because someone chose to give. During my first year at Makerere, I contributed to some young man’s school fees back home in my community. The young man is now in his second year at Makerere. You don’t have to be wealthy to make an impact; be intentional in your giving, and you will witness the difference it makes. There is no greater fulfilment than helping someone in need,” Akwara stated.
The event was punctuated with a number of activities that ranged from auctioning items, raffle draws, exhibitions, quizzes and a lot of games and fun.

Makerere University, through the Makerere University Convocation (MUC), has hosted the first-ever CEOs/Investors’ Round Table Summit on Tuesday, 2nd September 2025. The historic event brought together alumni, Chief Executive Officers (CEOs), and stakeholders in a distinguished assembly aimed at re-imagining the university’s role in national and continental transformation.
The Convocation, which serves as a critical forum for foresight and life-transformational dialogue, unveiled five transformative points carefully crafted to transform Makerere from a symbolic “ivory tower” into an “impact tower” that influences the country and the world more than ever before.
Government Endorsement and Call to Action
The Chief Guest, Prime Minister Rt. Hon. Robinah Nabbanja, was represented at the event by the 3rd Deputy Prime Minister, Rt. Hon. Rukia Nakadama Isanga. She conveyed warm greetings from H.E. the President of Uganda, Gen. Yoweri Kaguta Museveni, and the Rt. Hon. Prime Minister.
She commended the Convocation for convening under the summit under a significant and timely theme: “Exploring the Opportunities for Entrepreneurship, Innovation and Value Creation for Accelerated Socio-Economic Integration and Development of Sub-Saharan Africa.”
She described the summit as not just a gathering but a journey and a call to action, urging academia, industry, and government to align efforts with Uganda’s and Africa’s transformation priorities.
Framing her remarks around the World Bank’s guiding principles—Trust, Humility, Inclusion, Collaboration, and Knowledge—she explained:
- “Trust must be built between government, academia, and business… the gathering reflects the trust in CEOs and investors to walk this journey together.”
- “Humility requires listening and learning, recognizing that no single institution has all the answers.”
- “Inclusion reminds us that no youth, woman, or marginalized group should be left behind in transformation.”
- “Collaboration is the currency of progress, necessary for solving complex challenges across sectors.”
- “Knowledge remains our greatest asset, with Makerere University demonstrating its importance in moving from ivory towers to communities to transform lives.”
She then unveiled a “massive transformation purpose”, commissioning five working teams led by CEOs and investors. The teams, nominated lead persons, and their respective objectives included:
- From Ivory Tower to Impact Tower – Dr. Patricia Ojangole (UDB) with Patrick Ayota (NSSF), translating research into market-ready innovations.
- Diaspora Dividend vs Brain Drain – Jennifer Bamuturaki (Uganda Airlines) with Michael Mugabi (Housing Finance Bank), harnessing diaspora capital, skills, and mentorship.
- Intergenerational Knowledge Bridges – Fabian Kasi (Centenary Bank) with Ajay Kumar (Quality Chemicals), institutionalizing mentorship and reverse mentorship.
- Climate and Infrastructure Leadership – Proscovia Nabbanja (UNOC) with Silver Mugisha (NWSC), anchoring research in energy security, green transition, and infrastructure.
- Pan-African Digital and AI Advantage – Sylvia Mulinge (MTN Uganda) with Mumba Kalifungwa (Stanbic Bank), positioning Makerere as Africa’s digital and AI hub.
She pledged full government support, noting that the teams would convene in the Office of the President. “This summit is not ceremonial but a covenant,” she stressed.
The Minister’s Reflection
Hon. Balaam Barugahara, State Minister for Gender, Labour and Social Development in charge of Children and Youth Affairs, emphasized that the summit was not a party but a process of transformation.
Drawing from personal experience, he recalled joining Makerere in 2000 and completing his degree in seven years due to balancing work, hustling for fees, and studying. He praised the university’s role in shaping his success and highlighted recent developments such as the renovation of Mary Stuart Hall and revamping the Main and Western gates, as milestones that have enhanced Makerere’s image. He equally applauded the curbing of staff and student unrest.
He noted that the summit aimed to facilitate networking, mentorship, career opportunities, and university development, signalling collective commitment to Uganda’s transformation.
Council’s Vision: A Legacy Re-imagined
Representing Makerere University Council Chairperson Ms. Lorna Magara, Prof. Sarah Ssali described the summit as a “historic alumni CEO investor round table” and a reaffirmation of Makerere’s role in Africa’s development. She described the university as a “cradle of leadership, innovation and resilience”, noting that the gathering’s objectives included fostering partnerships, showcasing research, launching a fundraising drive, and strengthening alumni engagement. Prof. Ssali emphasized that alumni relations must go beyond occasional financial contributions during events, to continuous communication and genuine relationships. “This summit marks the start of a journey, not just an isolated event,” she reechoed.
Vice Chancellor on Unlocking Makerere’s Potential
Reflecting on the theme of his bid for the Office of Vice Chancellor, “Unlocking the Potential of Makerere University,” Prof. Barnabas Nawangwe noted that while many only celebrate the absence of strikes, behind the calmness is a vibrant transformation.
He highlighted Makerere’s alumni strength, with over 20,000 CEOs globally, and underscored their contributions to Uganda’s economy, governance, health, sports, and research. “What would Uganda do without Makerere?” he pondered. Prof. Nawangwe quickly added that the moment was ripe for Makerere to collaborate more with diaspora alumni so as to tap into fast-evolving niches such as blockchain.
Convocation’s Strategic Role
MUC Chairperson CPA George Mugabi Turyamureeba outlined the Convocation’s mission to support the university’s growth and well-being. He highlighted innovations such as the Convocation House, the annual luncheon for first-class graduates and their parents, mentorship programs, and the MUC SACCO as initiatives that his team had established and promoted during the term so far. The Chairperson nevertheless urged the CEOs present to enable the Convocation have greater impact collaborating on existing as well as envisaged projects such as the Convocation Innovation Centre.
Adding her voice, Vice Chairperson Ms. Grace Cherotich Ruto urged participants—described as “movers and shakers” of Uganda’s economy—to ensure that their decisions today would be celebrated by future generations.
Keynote Address: The Journey’s Just Began
In his keynote, Dr. Peter Kimbowa, Founder and Board Chair of the CEO Summit and Makerere alumnus, congratulated his alma mater on the initiative and reaffirmed the Convocation’s strategic role.
He emphasized that the Round Table Summit should not be seen as a one-time event but as an ongoing journey, echoing American Football Player Jalen Hurts’ mantra: “There’s no arrival. Only the journey.” Dr. Kimbowa defined the Convocation as a community of leaders, alumni, and faculty united by heritage and vision. He described it as a bridge connecting:
- The past to the future,
- Business and industry to academia, and
- Learning to market needs.
He stressed that the Convocation’s ultimate goal was to transform Makerere into a self-sustaining engine of innovation, opportunity, and national transformation. Drawing on corporate insights, he challenged participants to always ask “what is the next opportunity?” and warned against complacency. He unpacked the massive transformation purpose structured around five working teams which MUC has developed, whereby corporate chief executives from Uganda are called upon to lead collaboration with the university. He highlighted the importance of mobilizing talent to connect with successful Ugandan alumni, underscoring the need for local CEOs to harness talent in the diaspora. He emphasized deliberate action, mobilization of global alumni talent, and collaboration between CEOs and the university to sustain transformation
Panel Discussions and Triple Helix Framework
The day’s panel discussion featured Mr. Samuel Mwogeza (Executive Director, Stanbic Bank), Mr. Peter Sibukule (Headmaster, Busoga College Mwiri), Mr. Clovice Bright Irumba (Petroleum Authority of Uganda), and Ms. Grace Cherotich.
Mr. Mwogeza stressed the need to commercialize university prototypes and ideas. He explained that banks like Stanbic use their networks to strengthen innovators’ business cases, preparing them for market entry. Mr. Sibukule on the other hand called for transformation of mindsets right from secondary school level so that students are well primed to communicate, collaborate, uphold integrity and good work attitudes over qualifications in the marketplace. Mr. Irumba highlighted efforts by the PAU to create more opportunities for Ugandan entities to get involved in the oil and gas sector thanks to gaps highlighted by a study undertaken by the Economic Policy Research Centre (EPRC). Ms. Cherotich on the other hand invited CEOs to take interest in research outputs of the Makerere University Research and Innovations Fund (Mak-RIF) and reassured the audience of the Convocation’s readiness to provide a trusted platform for engagement with industry.
Contributing to the day’s discussion, Prof. Eriabu Lugujjo, Executive Director of the Uganda Vice Chancellors’ Forum (UVF), reminded the audience of the “Triple Helix” model and it’s underlying policy frameworks that in the recent past guided collaboration between universities, government, and the private sector. He observed Uganda’s lack of a robust framework, and called for policies that tie tax incentives to university support by corporations and other business entities.
Proceedings
The inaugural edition of the summit was moderated by Dr. Tayeebwa William from the Department of Journalism and Communication who doubles as Managing Editor Makerere University Press and Dr. Viola Karungi from the Department of Performing Arts and Film (PAF).
The PAF team took charge of the leading the anthems and day’s entertainment, which included a poetic presentation of the Makerere University Anthem.
