CoNAS Moves to Popularise the Bachelor of Science Programme, Improve Performance in the Subject of Biology
Overview
Basic biological research offered by the School of Biosciences at the College of Natural Sciences (CoNAS), more so at the Department of Zoology, Entomology and Fisheries Sciences (ZEFS) requires continuous recruitment of trainees to ensure its sustainability at Makerere University. Over the years, there has been a decline in the number of students admitted to offer biological courses at the School of Biosciences due to poor performance, but also the negative perception about the courses. These courses are often termed as “FLAT” during career guidance at high school, an indication that even the career teachers do not have a clear understanding of the Bachelor of Science degree programme. The perception that the programme is flat with no job prospects makes it unpopular, yet basic sciences are a pivot for several other applied sciences that significantly contribute to the wellbeing of humans and the economy of the country. For example, studies in basic Zoology, Botany, Chemistry and Biochemistry are a basis for effective understanding of applied courses such as plant breeding, vector control, wildlife management, plant pollination, environmental conservation, veterinary science, and human health management, among others. The decline in uptake of these programmes is a big challenge as it is likely to affect the learning of applied sciences.
The reduced recruitment of students into basic sciences has long term implications of missing on key scientists to support research in various scientific fields, yet the graduates of Bachelor of Science degree have numerous opportunities to undertake research and academic work in several national and international research institutions, academic institutions, and the private sector. The use of the term “FLAT” by career masters reflects the lack of clear understanding of the vast opportunities that this course exposes the candidates to, both in public and private sectors.
Plans to popularise the Bachelor of Science programme
To increase uptake, CoNAS has embarked on a programme to popularize the courses offered at the School of Biosciences among high school science teachers and learners by deciphering the myths associated with the Bachelor of Science degree. Broadly, the action aims at arousing the interest and improve academic performance among high school students in biology, and ultimately increase the students applying for the courses offered at the Department of Zoology, Entomology and Fisheries Sciences. Specifically, the programme aims to popularize research by early career researchers in the Department of Zoology, Entomology and Fisheries Sciences in selected schools with A-level biology students, as well as biology and career teachers. The Department of Zoology, Entomology and Fisheries Sciences will engage selected schools to share progressive research, experiences and lessons learnt to cultivate/arouse interest among the biological students in high schools. During the engagement sessions, the team will discuss possibilities to improve performance in biology and inform the next course of action.
The programme is coordinated by Dr Godfrey Kawooya Kubiriza, a Lecturer in the Department of Zoology, Entomology and Fisheries Sciences and a postdoc fellow for CECAP. It is part of the activities supported under his project on “Popularizing early career research for increased visibility of the Department of Zoology, Entomology and Fisheries Sciences”.
CoNAS engagement with Secondary School Biology teachers
On 26th July 2023, the CoNAS through the Department of Zoology, Entomology and Fisheries Sciences held a seminar for Secondary School teachers from selected schools around the country. The one-day seminar was funded by the Carnegie Corporation of New York, through the Directorate of Research and Graduate Training at Makerere University. It was intended to bridge the gap between the School of Biosciences, Makerere University and high school biology teachers in Uganda. It was also aimed at sensitising the teachers about the programmes at CoNAS, the importance of the Bachelor of Science programme and the opportunities it presents. The Seminar held at ZEFS was graced by the Commissioner in charge of Crop Inspection and Certification at the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF), Mr. Paul Mwambu; the Principal of CoNAS, Prof. Winston Tumps Ireeta, and senior academics from the School of Biosciences, Makerere University.
During the engagement, academics from the School of Biosciences sensitized the teachers on the programmes in their departments, highlighting the different course units, research activities, career prospects and opportunities, and emphasizing the importance of the BSc programme.
The Dean, School of Biosciences, also Patron of the Biology Society of Uganda (BioSU) delivered a presentation on the past, present and future dynamics of biology, stressing its relevance in driving the world systems in the next century. He also briefed participants on the BioSU and its intended purpose to improve performance in the subject of biology that has been declining over the years. A research conducted in the performance of Biology at the UACE sitting of 2018 whose results were released in February 2019, indicated that a total of 13,061 candidates sat for Biology countrywide, and of these only 1 candidate scored an “A”. That year, only up to 38% of the candidates scored at least an “E” leaving almost 80% failed (score O or F). In the next year’s sitting of 2019, only 44 candidates countrywide scored “A” in Biology. This trend was found quite repeated several times before 2018 and has not improved to-date post COVID-19. To solve this problem, Makerere University through the School of Biosciences at CoNAS in partnership with the College of Education and External Studies (CEES) under the supervision of the office of the Deputy Vice Chancellor in charge of Academic Affairs has embarked on a programme to identify the root causes of poor performance, by undertaking a detailed and carefully planned analysis of the qualifications, competence, and availability of Biology teachers and technicians at A’ level; the scope- breadth and depth of Biology curriculum at A’ level; how topics are segregated or not segregated in different UNEB past papers of Biology at A’ level in comparison to other A’ level subjects; the state of laboratory and field infrastructure for teaching Biology at A’ level; and attitudes of learners/students towards Biology at A’ level.
During his presentation, Prof. Tugume appealed to government to support and promote skilling programmes, noting that there are many people who have not had an opportunity to acquire University education but are doing wonders because of the skills attained from vocational training.
At the same meeting, Dr Kubiriza presented the research activities at the College, specifically in the Department of ZEFS, whereas Mr. Paul Mwambu, Commissioner in charge of Crop Inspection and Certification at MAAIF narrated how his study of the Bachelor of Science programme had exposed him enormous employment opportunities.
During the engagement, the secondary school teachers shared the challenges they experience and brainstormed on strategies that can be used to demystify the negativity about the Bachelor of Science programme. They also shared ideas on how to improve performance in subject of biology, emphasizing the need to review the syllabus and to retool the teachers. “The syllabus is so wide and this could be one of the lead causes of poor performance in the subject,” Prof. Tugume noted.
In his remarks, the Principal of CoNAS, Prof. Winston T. Ireeta emphasized the importance of career guidance and sharing of resources to improve performance. He pledged the College support towards secondary school career guidance programmes and retooling of teachers.
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.
