Remarks by the President
Speaking at the ceremony, the President of the Republic of Uganda, H.E. Yoweri Kaguta Tibuhaburwa Museveni who attended virtually re-echoed the importance of science in development. “The trigger of social change is science. I appeal to Ugandans and social scientists to understand this. When Africa was colonized, it was not that we lacked Kings, Magicians, Priests, we lacked science. Science was not emphasized. What was emphasized was these other actors. We want to emphasize science because it is the basis of socioeconomic transformation,” he explained, recommitting to facilitate government scientists better. “We have insisted on giving good salaries to Government scientists including science teachers in public Universities and secondary schools. This is not because we have forgotten the social scientists and arts people. This is because we cannot handle all at a go,” he noted. Additionally, the President emphasized the need for collaborative research. Commenting on security on Campus, he pledged to facilitate the completion of the University Perimeter wall.
Remarks by the Minister of Education and Sports
Delivering her remarks, the First Lady, also Minister of Education and Sports, Hon. Janet Kataaha Museveni who also attended virtually congratulated the graduands and their parents for the success registered. She thanked the University Management for their commitment in ensuring students attain quality education. “Together with our partners in development, we are still struggling to improve the working conditions, revamp the university infrastructure and to have new curriculum. We are grateful to our partners who have stood with us but most of all the government. We are specifically grateful to the NRM government because it shepherds the Ugandan child from childhood by providing basic health and education services. Government hope is that the Parish Model will empower the family to support the other education requirements of children. As we celebrate 100 years, we thank God for where He has brought us from. From 14 students, the University now has over 3,8000 students. This is no mean achievement. We must stand together. Let nothing divide us in our pursuit to transform the University and country. We should learn to embrace dialogue in conflict resolution,” she noted. The First Lady appreciated the Government for the enormous investment in research at the University. “Through government processes, we received funding for the construction of a 300-bed teaching hospital. This will greatly improve the teaching infrastructure at the University.”
The Chairperson, Makerere University Council
Addressing graduands, the Chairperson, Makerere University Council, Mrs. Lorna Magara appreciated the Vice Chancellor for the great service rendered to the University for the years he has held the Office. She presented an award to Prof. William Bazeyo, for his exemplary service as Deputy Vice Chancellor, Finance and Administration. During his tenure, Prof. Bazeyo played a tremendous role in soliciting for funding for the University, leading to a reduction of the University debt from UGX120 billion in 2017 to less than UGX 10 billion currently.
Remarks by the Chancellor
The Chancellor, Prof. Ezra Suruma appreciated the President and the First Lady, for their exceptional leadership and persistent determination in managing the Covid19 pandemic. “Despite the enormous economic, social and political pressures that you faced, you refused to relent in the face of the havoc of covid19 upon the world in general and Uganda in particular. I believe that your firm stand on vaccination and on preventive lockdown helped to save thousands of lives of Ugandans who would probably have died.” The Chancellor also appreciated the Government of Uganda for the commitment towards advancing research and higher education in the Country.
In his address, the Chancellor congratulated the graduands and paid tribute to the parents and guardians for the sacrifices made to ensure their children attain quality education. “I plead with the graduands to never forget to cherish and to honour your parents, guardians and sponsors who have sacrificed so much to help you reach this graduation day. As they become older, they will increasingly need your love and financial support. Whenever I meet someone I assisted and he or she tells me how they cherished my support I feel greatly uplifted. But whenever I remember someone I assisted but who has never bothered to send even a message of greetings, I feel discouraged. Please endeavor to cultivate an attitude of gratitude,” he advised.
The Chancellor appreciated Makerere University Management and faculty for the commitment and time invested in delivering quality education to the students.
The Vice Chancellor’s address
The Vice Chancellor congratulated the students and professors on the achievement. He thanked the parents, guardians, Government, and other sponsors, for supporting the students. “A total of 254 of this week’s graduands have been supported under the Government of Uganda Students’ Loans Scheme under the Higher Education Students’ Financing Board (HESFB). Since 2014, the Students’ Loan Scheme has supported 1,816 Students to study different Science Programmes at Makerere University, making it the single biggest supporter of private students at the Institution. These students would otherwise never have achieved their higher education dreams if it was not for the Students’ Loan Scheme. I wish to congratulate you the beneficiaries and appeal to you to use the skills and knowledge you have acquired to serve your country but also remember to pay back such that more students can be supported.”
Similarly, the Vice Chancellor appreciated all development partners who have supported many students to attain quality education at Makerere, including the Mastercard Foundation, Sida, Norad, The Madhvani Foundation, the Inter-University Council of East Africa, as well as Government Ministries and Agencies.
The Vice Chancellor thanked the University Council for expanding the Female Scholarship Scheme to support 40 girls from disadvantaged backgrounds, with special attention to Uganda’s ethnic minorities, including the Ik, the Dodoth, the Batwa, and the Jie. “It is also my pleasure to report that the University Council policy on affirmative action for girls in STEM is already bearing fruit. Because of that policy, the enrolment of girls in STEM has increased from 35% to 42% over the last two academic years.”
Regarding research and innovation at Makerere, the Vice Chancellor appreciated the Government for the allocation of UGX 30 billion annually for the last three years towards the Research and Innovation Fund, commonly referred to as RIF. “This fund has transformed Makerere tremendously. Out of 1,200 applications received, more than 700 research grants have so far been allocated and more than 500 innovations have been recorded, many of them with potential for commercialization, and a number of policy briefs and manuals have been developed. The Government of Uganda is now the single largest funder of research at Makerere University and we are obliged to respond by increasing our efforts to find solutions to our Country’s development challenges. Our potential for innovation came out during the COVID-19 pandemic when more than 200 innovations to fight that disease were realized. I congratulate the Makerere researchers for their patriotism and zeal.”
He also appreciated the Government for the considerable investments in improving Makerere University infrastructure. “Last week the First Lady and Minister of Education and Sports came to Makerere to commission some buildings and lay foundation stones for others, including the reconstruction of our iconic Main Administration Building, for which Government has already availed all the UGX 21 billion required. The new building for the School of Dentistry has enabled us to equip the biggest dental hospital in East Africa. The Central Teaching Facilities have greatly alleviated the shortage of teaching and office space, and the new building for the School of Law will enhance research and graduate training in the discipline of Law. All these projects will cost the Government more than UGX 60 billion and we thank you very much indeed.”
The Vice Chancellor equally thanked the President for the pledge to support the construction of a perimeter wall around the University campus. He also appreciated the President for his directive for the allocation of funds to renovate student halls of residence and facilities of the College of Health Sciences. “These facilities are central to student welfare and the quality of our teaching and training. With these investments, I want to assure Your Excellency that we shall give our best to build the human capital of this country and enhance research and innovation to drive the national development agenda. The grant of USD 300 million negotiated by the First Lady and Minister of Education for the construction of a teaching hospital at Makerere University will greatly revolutionise teaching and research at Makerere. Makerere will never be the same again,” he noted. He also extended gratitude to the government for the pledge of UGX 800 million to support activities to mark 100 years of Makerere University. This year, Makerere is celebrating 100 years of excellent service to humanity. The climax will be on 8th October 2022.

A team of researchers from Makerere University has presented findings of a study on the persistent poor performance in Biology in national examinations to senior officials at the Ministry of Education and Sports.
The findings were shared during a dissemination meeting attended by the Ministry’s top management, led by Permanent Secretary Kedrace Turyagenda.
The study, commissioned by the Ministry in 2023, was conducted by researchers from the College of Natural Sciences (CoNAS) and the College of Education and External Studies (CEES). It was spearheaded by Prof. Fredrick Muyodi as Principal Investigator, alongside Assoc. Prof. Josephine Esaete (Co-Principal Investigator) and Prof. Arthur Tugume among others.
Titled “Examining the Factors Accounting for Poor Academic Performance in Biology in Uganda’s National Examinations,” the study covered all regions of the country, engaging more than 5,200 respondents across 100 districts through surveys, interviews, and observations.
Key findings
The research identified limited field-based learning and poor digital access as the most critical and consistent challenges affecting both Ordinary and Advanced Level students across all regions.
At Advanced Level, the lack of project-based learning was also cited as a significant constraint. Learners reported limited engagement with Biology beyond the classroom, a factor that weakens conceptual understanding and application in examinations.
The study further highlighted the role of community attitudes and perceptions in shaping student performance in the subject.
Recommendations
The researchers recommended increased investment in field-based learning, including field trips and project work, as well as expansion of digital infrastructure to improve access to learning resources.
Other proposed measures include strengthening school laboratory facilities, enhancing teacher capacity through continuous professional development, promoting student engagement through academic clubs and mentorship programmes, and fostering stronger family and community support for science education.
Next steps
The research team is seeking funding to pilot targeted interventions, particularly in regions most affected by the challenges identified, and to develop a monitoring and evaluation framework to guide implementation.
The findings are expected to inform policy and interventions aimed at improving Biology performance and strengthening science education in Uganda.

Transforming Food Waste into Clean Energy: Makerere University Researchers Equip Mbarara City Residents with Biogas Production Skills
*****Led by Dr. Patience Tugume from the Department of Plant Sciences, Microbiology and Biotechnology at Makerere University, a project titled “Bio-innovation of biogas, biofertilizer, and biopesticide through the utilization of bio-waste” is promoting the transformation of household food waste into biogas and other valuable bio-products. The project team disseminated the research findings to stakeholders in Mbarara City on 15th April 2026.
About the Project
A one-year bio-innovation initiative focused on converting household food waste into biogas, biofertilizer, and biopesticides has yielded promising results in improving access to clean energy and promoting sustainable agricultural practices in peri-urban communities of Mbarara City.
The project, implemented by Makerere University in collaboration with Frevasema Ltd in Mbarara, was supported by UNESCO and the International Development Research Centre (IDRC) – Canada through the Organization for Women in Science for the Developing World (OWSD). Launched in January 2024, it is led by Dr. Patience Tugume from the Department of Plant Sciences, Microbiology and Biotechnology at Makerere University.
The initiative has been implemented across five divisions of Mbarara City – Kakoba, Kamukuzi, Nyamitanga, Biharwe, and Nyakayojo – with additional field trials conducted in Masha Sub-county, Isingiro District.
Objectives of the project
The central aim of the project was to demonstrate how biodegradable household waste can be transformed into useful products, particularly biogas for cooking, as well as organic biofertilizers and biopesticides for improved crop production.
Key objectives of the project included: establishing a spin-off centre of bioreactors at the business partner institution (Frevasema Ltd) to demonstrate sustainable production of biogas, biopesticides and bio-fertilizers; training and equipping women and youth with hands-on skills in biogas production and usage; evaluation of yields from different bio wastes; and creation of linkages between academia, the private partner and rural communities in up-scaling production of biogas, biopesticides and bio-fertilizer from household/urban biodegradable wastes.
Key Activities and Dissemination of Project Findings
The project team conducted a survey to assess community perceptions and the factors influencing the adoption of biogas as an alternative cooking energy source in peri-urban areas of Mbarara City. In addition, biodigester tanks were constructed at FREVASEMA Ltd to support training and knowledge transfer activities.
Field experiments were undertaken in Masha Sub-county, Isingiro District to evaluate the effectiveness of an integrated biofertilizer–biopesticide. Further experiments to assess biogas yield from different types of food waste were conducted at Makerere University.
The team also developed an integrated biofertilizer–biopesticide by enhancing bioslurry, a by-product of biogas production, with plant extracts known for their pesticidal properties. The effectiveness of this product was tested on the growth performance of green pepper, cabbage, and eggplant.
In line with one of the project objectives, the team also conducted hands-on training in biogas production from food waste for 35 students and 6 staff members of MAMITA Technical and Business Institute.
Dissemination workshop
On 15th April 2026, the project team led by Dr. Tugume held a dissemination workshop to share findings with stakeholders and discuss strategies for scaling up the outcomes.
Findings from the research highlight the strong potential of biogas in contributing to sustainable energy solutions, improving livelihoods, and enhancing environmental conservation through proper food waste management.
Key research findings
- The application of integrated biofertilizer–biopesticide presents a viable alternative to scarce, expensive, and environmentally harmful inorganic fertilizers for enhancing vegetable productivity.
- The study revealed that approximately 90.7% of respondents depend on charcoal and firewood as their primary cooking fuel.
- While 92.1% of respondents were aware that biogas is produced from animal and plant materials, only 7.9% recognized that food waste can also serve as a feedstock, indicating limited awareness of its full potential.
- Banana and potato peels, as well as posho and potatoes leftovers, and green vegetable trimmings, were identified as the most commonly generated food wastes.
- A majority of respondents strongly agreed that biogas is a cleaner and more sustainable energy alternative compared to firewood.
- Key barriers to biogas adoption included inadequate technical knowledge, safety concerns regarding biogas systems, and the high costs of constructing and maintaining biodigesters.
- The extremely low adoption rate of biogas technology (0.3%) indicates significant underutilization despite its potential to mitigate fuel shortages.
- There is a prevailing perception that biogas is suitable for cooking and can effectively replace biomass fuels, given the availability of sufficient feedstock from household food waste, human waste, and animal manure.
- Potato and posho residues were identified as the most suitable primary feedstocks for biogas production due to their high nitrogen content, volatile solids, and total organic carbon (TOC).
- Effective collection and proper segregation of food waste are essential for ensuring a consistent and uncontaminated supply of feedstock for biogas production systems.
- Further research is recommended on integrated biogas systems that combine anaerobic digestion with other renewable energy technologies, such as solar energy or bioelectrochemical systems, to improve overall energy recovery efficiency.
- Vegetables treated with the integrated biofertilizer–biopesticide consistently exhibited superior performance across all growth parameters compared to those treated with inorganic fertilizers (including 5% cypermethrin pesticide) and untreated controls.
Stakeholder engagement and appreciation of the initiative
During the dissemination workshop, Dr. Patience Tugume, the Principal Investigator, expressed gratitude to UNESCO and the International Development Research Centre (IDRC)-Canada, through the Organization for Women in Science for the Developing World (OWSD), for funding the project. She appreciated the research team composed of Dr. Asiimwe Savina, Prof. Maud Kamatensi-Mugisha, Prof. Bazirake Byarugaba, Ms. Catherine Kiconco and Mr. Muhumuza Robert for their contribution. She equally appreciated all participants for contributing valuable information to the study.
Stakeholders commended the project for its relevance and community impact.
Prof. Bunny Lejju Julius from Mbarara University of Science and Technology, appreciated the project team for developing an innovation that directly addresses community needs and aligns with the principles of the competency-based curriculum, particularly the translation of academic knowledge into practical application. He advised that sustainability of the initiative could be strengthened through a multiplier approach, where the trained learners cascade the knowledge to other community members. He further recommended the identification of institutional staff who can undergo training at the spin-off centre and subsequently serve as trainers within their respective communities.
The portable biodigester system was recognized as a simple, affordable, and practical technology with the potential to provide a cost-effective alternative to charcoal and electricity. Participants noted that while resistance to change remains a challenge, continuous awareness creation is essential to promote adoption and facilitate behavioral change.
Mbarara District Forest Officer, Ms. Ainembazi Joses, highlighted the importance of the biogas production project in environmental conservation. She noted that the initiative contributes to reducing deforestation by offering an alternative to firewood and charcoal, thereby supporting sustainable natural resource management.
The Local Council Chairperson of Mailo-Biharwe Division, Mr. Didas Katabazi, appreciated the project team for the innovative work and its potential benefits to the community. He pledged to use his office to advocate for increased government support to scale up the project.
The Resident City Commissioner of Mbarara City expressed concern over the rising levels of deforestation in the district and commended the Principal Investigator for spearheading the innovation. He reaffirmed the government’s commitment to supporting science and innovation. He emphasized the importance of integrating environmental protection with agricultural productivity, explaining that food security remains a national priority. He further noted that the project demonstrates the concept of waste valorization, where organic waste is transformed into valuable products such as biofertilizers and biopesticides, thereby enhancing agricultural productivity. He pledged to engage the Office of the President to support wider dissemination of the project outcomes. Additionally, he encouraged the trained students to act as ambassadors of the project by sensitizing communities on the benefits of biogas as an alternative source of cooking energy.
Way forward
- The government should invest in constructing bio digesters for households at subsidized prices or offer them financial assistance to cater for bio digester construction.
- Awareness campaigns about the production and use of biogas and associated benefits should be intensified in communities to dispel the negative perceptions.
- Provision of technical training in operating and maintenance of biogas installations should be conducted.
- Sorting of wastes at household level should be emphasised to separate biodegradable from non biodegradable ones.
- The integrated bio-fertilizer-bio-pesticide is an effective, sustainable strategy to increase vegetable productivity while improving soil health in nutrient-limited soils.
- The project recommends adoption of bio-fertilizers (e.g., bio-slurry) which are affordable and can be made from kitchen and market waste to reduce dependence on expensive chemical fertilizers to improve crop growth while controlling pests safely in addition to being safe for humans and the environment.
Donation of portable biodigester systems
As part of the commitment to translate research into tangible benefits, the project awarded two women and MAMITA Technical and Business Institute with portable biodigester systems for installation and use in their households and institution respectively. These systems will serve as demonstration units within the community showcasing the practicality, affordability, and impact of clean energy solutions at the household level.
