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.

Meet Sedrick Nuwagaba, a Mastercard Foundation Scholars Program Alumni Contributing to Uganda’s Oil & Gas Industry
Sedrick Nuwagaba, a 35-year-old petroleum engineer, is actively contributing his expertise to the Petroleum Authority of Uganda, which regulates the oil and gas sector. He obtained his Bachelor of Science in Petroleum Geoscience and Production from Makerere University in 2021, an opportunity he accessed through the Mastercard Foundation Scholars Program. Sedrick’s educational qualifications and professional responsibilities exemplify his commitment to advancing Uganda’s oil and gas sector.
Who is Sedrick Nuwagaba?
Sedrick was born on February 1, 1990, in Kashari, located within the Mbarara district of Western Uganda. He spent his early childhood in a large family, where he faced many challenges that shaped his resilient character. By the age of 14, Sedrick had become the primary breadwinner for his immediate family, comprising his mother and two sisters. His unwavering commitment to their well-being remains evident to this day.
To support his family during these formative years, Sedrick took on a variety of jobs in his community. These early experiences cultivated in him resilience and tenacity, qualities that have significantly contributed to his success as a petroleum engineer.
Following these family challenges, Sedrick and his immediate family relocated from Kashari to a new area in what is now Lyantonde district, where they continue to reside. His journey not only reflects personal growth but also underscores a steadfast commitment to uplifting those around him.
Early Education
The implementation of Universal Primary Education (UPE) in Uganda in 1997 was a pivotal development for Sedrick, facilitating his enrollment at St. Martin Lyantonde Primary School at the age of seven, which was conveniently located near his residence. Sedrick expresses deep appreciation for this initiative, commenting, “Without UPE, I might not have had the opportunity to pursue my education. It truly opened the door for me to attend school and engage in learning.” Despite confronting considerable challenges, including a lack of necessities such as food, Sedrick distinguished himself academically. He achieved top candidate status among UPE schools in his district, earning an impressive seven aggregates in the Primary Leaving Examinations—a remarkable accomplishment given the adversities he faced.
Pursuing Secondary Education
Sedrick faced significant challenges after earning 7 points in the Primary Leaving Examinations, as he was unable to secure a bursary. At that time, alternative arrangements for Universal Secondary Education were limited, which made it difficult for him to continue his education. However, demonstrating remarkable resilience, Sedrick sought work at 14 to fund his secondary education. Through his determination and resourcefulness, he enrolled at Victoria Western College, a small private school in his area, where he attended for three years, reaching Form 3.
Although financial barriers hindered his progress to Form 4, Sedrick’s journey shows his dedication to education and his ability to overcome adversity. Fortunately, his elder half-brother, a businessman in the neighbouring town of Mbarara, reached out and helped him enrol in Form 4 at Kashari Secondary School in Mbarara in 2007.
Embarking on a Journey to Iraq in Search of Opportunity
In 2008, facing difficulties in pursuing his education, Sedrick made the brave decision to take up a security job during the conflict in Iraq between 2003 and 2011. At that time, many young Ugandans were recruited to provide buffer security support to the U.S. military in Iraq. During his time in Iraq, Sedrick not only earned a stable income to support his family but also cared for his mother and funded his two sisters’ education, ultimately improving their lives. Unfortunately, his contract ended in 2010, and he had to return to Uganda to write the next chapter of his life.
Joining the Mastercard Foundation Scholars Program at Makerere University
Upon returning to Uganda after his experience in the Iraq War, Sedrick recognised that education was the key to transforming his life. With a determined mindset, he committed himself to his studies, understanding the long-lasting impact they could have on his future. Thanks to his perseverance and the relationships he had built, Sedrick obtained a bursary from a religious organisation, enabling him to resume his high school education six years after his last time in school.
In 2015, he completed his high school education at Namirembe Hillside, where he studied Physics, Mathematics, and Chemistry. With 15 points in his final exams, he was admitted to the Bachelor of Science in Petroleum Geoscience and Production program, supported by the Mastercard Foundation Scholars Program at Makerere University.
“Participating in the Mastercard Foundation Scholars Program at Makerere University significantly changed my life. For the first time, I was free from the constant worries about necessities like food and shelter. The Mastercard Foundation Scholars Program provided me with a supportive environment that allowed me to focus on my education and personal growth,” Sedrick shared.
Life After Makerere University
In 2020, after graduating, Sedrick had the opportunity to intern at the Uganda National Oil Company (UNOC) in the Reservoir Engineering section. During his internship, he demonstrated exceptional dedication and expertise in the oil and gas sector. His performance led to his promotion to a Graduate Trainee, which provided him with valuable experiential learning and expanded his exposure within the industry. This experience ultimately paved the way for his recruitment as a Petroleum Engineer at the Petroleum Authority of Uganda, where he now contributes to the regulation of petroleum exploration activities in the country.
Impact on the Community
Upon graduating from university, Sedrick took a proactive approach that set him apart from his peers. He launched Kleanerman, a social venture project designed to have a positive impact on his community. This initiative provides valuable short-term, on-demand domestic services—such as home cleaning, laundry, and babysitting—catering to the needs of busy city residents. Through Kleanerman, Sedrick has successfully created employment opportunities for several young men and women in his community of Kanyanya, fostering both economic growth and personal development.
Due to his own challenges during his educational journey, he has developed a deep commitment to helping other young people facing difficulties with school expenses. To date, he has successfully supported seven young individuals in his Lyantonde community, guiding them from primary through secondary education. His long-term goal is to establish a charitable organisation dedicated to providing young people facing barriers to education with the resources they need to access quality education.
Looking into the Future
Sedrick is dedicated to making a meaningful impact in Uganda’s oil and gas sector. He, along with his colleagues, is focused on ensuring that Uganda achieves its inaugural oil production by 2026.
“Each day, our collective efforts are directed toward successfully introducing Uganda’s first oil into the market by the end of 2026, and expanding the country’s petroleum resource base by discovering more oil reserves,” Sedrick states with evident pride. He is also committed to advancing his career in the oil and gas industry. From his earnings, he has enrolled for a Master’s degree in Petroleum Geosciences at Makerere University to deepen his skills and expertise in the sector.
Message to his fellow young people
Sedrick urges the current Mastercard Foundation Scholars enrolled in the Mastercard Foundation Scholars Program at Makerere University, as well as those at other universities, to make the most of the support provided by the Mastercard Foundation Scholars Program. He emphasises the importance of engaging in capacity-building sessions, skill development programs, mentorship opportunities, and psychosocial support. Sedrick asserts that this comprehensive support framework has been instrumental in transforming his life and shaping who he is today.
He references a quotation that has become a guiding principle in his life: “Until death, all defeat is psychological.” Through this quotation, he seeks to inspire his peers to persevere, emphasising the notion that individuals can always recover and succeed despite the myriad challenges they may encounter in their initial endeavours.
Words of Gratitude
“The impact of the Mastercard Foundation Scholars Program on my life is profound and transformative. I am sincerely grateful to the Mastercard Foundation Scholars Program at Makerere University and to the Mastercard Foundation as a whole. It is my hope and prayer that the Foundation continues to make a positive difference in the lives of numerous young individuals, particularly within the African continent.” Sedrick emphasises.
His supervisor speaks out
Sedrick’s immediate supervisor, Mr Derrick Katusiime, the Senior Petroleum Engineer in the Directorate of Exploration at the Petroleum Authority of Uganda, was full of praise for him both at work and outside.
“Sedrick is very sociable and gets along well with everyone here at work, and his technical skills in just two years are impressive,” Mr. Katusiime pointed out.
Mr Katusiime further revealed that Sedrick champions values of integrity, active listening, and being an excellent team player. He goes the extra mile to complete tasks, takes on multiple responsibilities, and demonstrates humility and eagerness to learn.

A few weeks shy of celebrating a decade of advancing lung health for all through research, training and patient care, the Makerere University Lung Institute (MLI) on 4th November 2025 unveiled a landmark expansion project, set to provide world-class care and contribute to global lung health research. The proposed six-level facility will house the Centre for Advanced Pulmonary and Intensive Care (CAPIC), Centre for Clinical Investigation (CCI), and Centre for Capacity Enhancement (CCE). Upon completion these units will deliver advanced respiratory care, cutting-edge research, and specialist training for pulmonologists, thoracic surgeons, and respiratory scientists. MLI’s year-long celebrations of a decade of existence will culminate in a grand event to be held on 27th and 28th November 2025.
Officials laud MLI Milestones
Addressing officials at the site handover ceremony who included the Executive Director, Mulago National Referral Hospital (MNRH)-Dr. Rosemary Byanyima, Chairperson MLI Board of Directors-Prof. Charles Ibingira, Founder and Director MLI-Prof. Bruce Kirenga among others, the Vice Chancellor Prof. Barnabas Nawangwe commended MLI on milestones such as treating 20,000 patients to-date. “Thank you Prof. Kirenga for having the vision to start and grow the Lung Institute, and to hear that you have already raised some of the funds to commence this phase of the project is commendable,” Prof. Nawangwe lauded.
The MLI Expansion Project (MEP) is valued at UGX 66.84Bn (US$18.06M) comprising of construction of a 5,139sqm building valued at US14.04 M, specialist training valued at US$ 1.43M, and equipment valued at US$2.59M. It will be located on Mulago Hill on land allocated by the MNRH Board of Directors, a gesture the Vice Chancellor sincerely appreciated the Executive Director Dr. Byanyima for.
“Thank you for offering this land Dr. Byanyima. Makerere University and Mulago National Referral Hospital as top institutions our country must work together because if Makerere succeeds at conducting research, the hospital benefits” added Prof. Nawangwe.
MLI’s Role in Advancing Lung Health
Dr. Byanyima in her remarks acknowledged that it was during the CoVID-19 pandemic that the importance of lung health and the role played by MLI was brought to the fore. “But I’m glad that (pandemic) made the Lung Institute grow stronger and on the Hill (Mulago) when we have a unit growing stronger, we have an obligation to support it, not that we abdicate our responsibilities, but we know that it is shared responsibility.”
She therefore thanked Prof. Kirenga for his foresightedness in always thinking of projects that benefit the public. “Mulago Hill does not expand; there are many needs and as MNRH we are looking for land elsewhere. So for the Lung Institute to have been given an opportunity to get a few square metres is because you showed justified cause,” complimented Dr. Byanyima.
The Chairperson MLI Board acknowledged that the Lung Institute has not only received support from MNRH but from its mother Ministry of Health, and other Government entities such as the Ministry of Science, Technology and Innovation, which is supporting MLI’s Clinical Trials Centre and the current expansion project. Prof. Ibigira equally thanked the University for the good policies that facilitate the creation and growth of centres of excellence.
“As the board, we pledge to ensure that this expansion project is executed with excellence, transparency and timeliness, and look forward to a facility that will stand as a beacon of hope in innovation and global excellence in lung health” remarked Prof. Ibingira.
In his remarks, Prof. Bruce Kirenga noted that it is critical that centres of excellence such as MLI are located around MNRH so as to synergize general and specialized healthcare services offered to the public. He therefore thanked Dr. Byanyima and the MNRH Board for not only allocating land for MLI’s expansion but also the two buildings within the Hospital complex that have boosted Institute operations since its founding in 2015.
“These two buildings house the Clinical Trials Ward and the Vaccine House, which is the biggest cold room for vaccines in the country apart from National Medical Stores. This has enhanced our capability in research, storage of vaccines, and most importantly, we can also store a large amount of investigational vaccines, and right now we are being profiled as a centre for stockpiling investigational vaccines on the continent” Prof. Kirenga elaborated, before adding “and we have the largest specialist clinic in the region for treating people with complex lung diseases.”
Scope of works
According to Eng. Ezra Sekadde, Head of the Project Management Team, the construction phase of the MEP has been divided into three stages; 1a to renovate an existing onsite structure for MLI operations, 1b to construct the six-level facility, and 2 to complete internal and external finishes as well as concrete paving and access road works.
Construction will be undertaken by CK Associates within a period of seven months. The Fundraising Committee for the MEP will be chaired by Prof. Tonny Oyana, the Principal, College of Computing and Information Sciences (CoCIS).
Under the theme, “Leveraging AI for Sustainable Transformation: Leading in Uganda’s Transformation in the Age of Disruptive AI,” the 16th Annual CEO Forum 2025 brought together government leaders, captains of industry, academia, and development partners to discuss how Artificial Intelligence (AI) can drive Uganda’s transformation agenda.
Representing the Vice Chancellor, Mr Yusuf Kiranda, University Secretary at Makerere University, reaffirmed the University’s pivotal role as a hub for AI research, innovation, and training anchored in strong partnerships across government, academia, and industry.
“Makerere University is responsible for research, innovation and training to ensure transferable knowledge that can be utilised by both the private and public sector,” Mr. Kiranda noted.
He emphasised that Uganda’s sustainable AI transformation will depend on effective policy, governance, and collaboration across sectors.
According to Mr. Kiranda, three key issues must be addressed for AI to realise its potential:
- Balancing control and facilitation: Policymakers must not only regulate AI but also actively enable its use to drive innovation and competitiveness.
- Sovereignty of AI: Uganda must safeguard its data and resources, especially in sectors like agriculture, where external mapping of local assets threatens national control and export competitiveness.
- Regional harmonisation: To ensure fair competition, AI policies must be aligned across East Africa so Ugandan, Kenyan, and Tanzanian businesses operate under a level playing field.
“In the utilisation of AI, if a policy is making Uganda less competitive, we must revise it now to allow private sector players to thrive in this disruptive age,” he added.
Mr. Kiranda further reiterated Makerere’s commitment to producing quality, AI-ready graduates and enhancing teaching and learning methods to integrate technology. He also acknowledged the Government’s continued investment in research at Makerere, which has seen a growing number of researchers focus on AI and technological innovations.
“I can attest to Makerere’s existing partnerships with government entities and development partners. These collaborations are making the market ready to deliver solutions through effective academia–industry partnerships,” he said.
Building Africa’s Digital Destiny
The forum opened with a powerful keynote from Dr. Robin Kibuka, Board Director at the CEO Summit Uganda, who spoke on “Building Africa’s Digital Destiny: Kampala Rising, Africa Inventing.”
Dr. Kibuka urged Africans to take ownership of their digital future, stressing that the continent must define how AI transforms its societies.
“Artificial Intelligence can empower Africa or divide it. The choice is ours,” he said.
He highlighted success stories from across Africa, including AI-powered drones delivering medical supplies and smart credit systems supporting small businesses — proof that the continent is already innovating its own digital solutions.
Leveraging AI for Sustainable Transformation
In her keynote address on “Leveraging Artificial Intelligence for Sustainable Transformation,” Dr. Preeti Aghalayam, Director of the Indian Institute of Technology Madras – Zanzibar Campus, described AI as “the defining disruptor of the 21st century.”
She emphasised that both Africa and India share a unique opportunity to collaborate in education, innovation, and human capital development to shape a more inclusive digital future.
“Artificial Intelligence must help us do better and be better,” she said, highlighting the need for responsible innovation that uplifts communities and promotes sustainability.
Digital Transformation in the Health Sector
Mr. Rashid Khalani, Chief Executive Officer of Aga Khan University Hospital, Uganda, presented on “Digital Transformation in the Health Sector,” sharing practical examples of how AI is redefining healthcare delivery.
From AI-powered radiology that detects anomalies faster, to predictive models for early sepsis detection and digital tools supporting mental health care, Mr. Khalani demonstrated how AI is improving patient outcomes and empowering medical professionals.
“AI is not replacing people. It is empowering them to deliver better care, faster,” he emphasised.
He noted that partnerships between hospitals, universities, and technology institutions are crucial in developing localised AI solutions that respond to real health needs.
Makerere at the Heart of Uganda’s AI Transformation
The discussions throughout the 16th Annual CEO Forum 2025 reaffirmed the critical importance of collaboration among academia, industry, and government in shaping Uganda’s AI-driven future.
Makerere University continues to play a leading role in this space, providing the research, innovation, and talent that power the country’s transition into a digital economy.
Through strategic partnerships, forward-looking policy engagement, and continuous innovation in research and training, Makerere stands at the forefront of preparing Uganda and the region for a smart, inclusive, and sustainable future powered by AI.
