Participants from the partner institutions at the opening ceremony of the workshop held on 21st September 2026

Mathematics is increasingly being applied beyond the classroom to help make sense of complex problems, explore possible solutions and support better decision-making in everyday life. From determining how public funds can sustain pension systems and identifying people at risk of disease to guiding investment decisions and optimising limited space, mathematical modelling provides a powerful way to translate real-world challenges into evidence that can inform action.

It is this practical application of mathematics that formed the focus of the five-day ICMS-CoRE-MATH Study Group in Industry, held from 21^st-25^th September 2026 at the Department of Mathematics, Makerere University. The Study Group brought together mathematicians, industry practitioners and regional and international experts to develop mathematical models for addressing challenges across sectors.  

Held under the Africa–Europe Cluster of Research Excellence in Mathematics (CoRE-MATH), in collaboration with the NORHED II Mathematics for Sustainable Development (Math4SDG) project, the workshop sought to strengthen the application of mathematical research to development challenges while deepening collaboration between academia, industry and society.

CoRE-MATH is co-led by Prof. John Mango Magero of Makerere University and Prof. Bengt Ove Turesson of the International Science Programme at Uppsala University, Sweden. The initiative brings together leading universities from both continents. African partner institutions include Makerere University, the University of Nairobi, the University of Rwanda, the University of Dar es Salaam, Addis Ababa University, the University of Zambia, and Stellenbosch University. These institutions collaborate with European universities such as Uppsala University, the University of Amsterdam, and the University of Oslo.

Purpose of the Workshop

Rather than approaching mathematics as an abstract discipline, the Study Group provided a platform for researchers to work directly on practical problems presented from different sectors. Through mathematical modelling, the researchers sought to break down complex challenges into measurable variables, analyze relationships between them and develop models that can be tested and refined to support decision-making.

Four areas were explored during the Study Group: public-service pension reform, hypertension risk prediction, aquaculture investment and food-court seating optimization.

Modelling Uganda’s Public-Service Pension Transition

One of the research groups, led by Dr Herbert Mukalazi, developed a mathematical framework to examine the fiscal implications and long-term sustainability of Uganda’s transition to the new public-service pension system.

The model is designed to help Government understand how much the transition to the new public-service pension system could cost over time and plan for these financial demands in advance. It shows how payments to existing pensioners and obligations under the new system may overlap, helping Government anticipate funding needs, avoid financial shortfalls and ensure that pension benefits can continue to be paid as expected.

Preliminary simulations indicate that the transition could place an additional financial burden on the Government, equivalent to approximately 1.14 percent of GDP, with the burden peaking around the 2028/29 financial year. The model also highlights the importance of investment returns to the Fund’s long-term financial position.

Under a scenario assuming a 6 percent annual nominal investment return, the model estimates that Government may need to make an additional contribution equivalent to about 2.14 percent of covered payroll to ensure the pension system has enough cash to meet its obligations throughout the simulated period.

The study illustrates how mathematical modelling can transform a complex public-finance challenge into measurable scenarios, allowing policymakers and other stakeholders to examine how different assumptions and policy choices could affect the pension system over time.

Predicting Hypertension Risk Using Available Health Data

In healthcare, Dr Rebecca N. Nsubuga is leading a team that is developing a mathematical model to predict an individual’s risk of hypertension using available demographic and health data.

The study seeks to categorize individuals into low-, moderate- or high-risk groups using variables including age, sex, residence, education and income, together with anthropometric measures such as body mass index and waist circumference where available.

 Using ordinal logistic regression and a generalized ordinal logistic regression approach, the researchers examined how different risk factors relate to progression across the different hypertension-risk categories.

Analysis of 100,000 observations identified significant associations between hypertension risk and several factors, including age, residence, education and income.

The model provides a foundation for developing predictive tools that could support the early identification of people at increased risk of hypertension, potentially enabling more targeted prevention and public-health interventions.

Using Mathematics to Inform Aquaculture Investment

Another study group, led by Dr. Godfrey Kawooya Kubiriza, developed a mathematical model to help investors make more informed decisions about aquaculture investments.

The model brings together key factors such as production costs, expected fish yields, market prices, risks and potential returns to show how changes in these factors could affect the profitability of an investment. This enables investors to examine different scenarios before committing resources and identify how changes in production or market conditions may influence expected returns.

The study demonstrates how mathematical modelling can provide a structured approach to investment planning in aquaculture, where biological, financial and market factors are closely interconnected.

Food-Court Seating Optimization

A fourth study, led by Dr Henry Kasumba, focused on food-court seating optimization, demonstrating how mathematical modelling can be applied to everyday operational challenges.

The study explored how available space could be organized to optimize seating arrangements while taking into account competing requirements and spatial constraints.

Although seemingly simple, the problem illustrates a broader application of mathematics: helping organizations make better use of limited resources by identifying arrangements that satisfy multiple requirements as efficiently as possible.

Strengthening the Link Between Mathematics and Society

The Study Group forms part of the broader efforts by Makerere University and its partners to strengthen the connection between mathematical research and real-world development challenges.

By bringing mathematicians and practitioners together to address real-world problems, the initiative supports the development of evidence-based models for decision-making while creating opportunities for further research and postgraduate studies.

The workshop was coordinated by Prof. John Mango Magero and Dr. Alex Behakanira, Senior Lecturer at the Department of Mathematics and member of the academic network contributing to capacity building and collaborative research activities in the CoRE-MATH initiative.

View on CoNAS

For communities living along Uganda’s lakes and rivers, water hyacinth is more than an invasive weed. Its rapid spread can choke waterways, disrupt fishing and transportation, restrict access to water and interfere with livelihoods and essential community services.

But what has for years been viewed primarily as an environmental menace could also become a source of economic opportunity.

Turning an environmental challenge into an opportunity

Researchers at Makerere University, with support from the Government of Uganda through the Makerere University Research and Innovations Fund (MakRIF), have demonstrated how water hyacinth can be harvested and transformed into useful, value-added products through a small-scale community bio-refining approach.

Their project, titled “From World’s Worst Water Weed to Worth: Small-scale Community Bio-refining of Water Hyacinth to Produce Value-added Commercially Valuable Products,” sought to shift the focus from simply removing and disposing of the invasive plant to exploring opportunities for value addition, innovation and enterprise.

Led by Dr. Alice Nabatanzi from the Department of Plant Sciences, Microbiology and Biotechnology at the College of Natural Sciences (CoNAS), Makerere University, the research was inspired by the experiences of communities affected by water hyacinth, including residents of Katosi Ward in Mukono District, where the weed has had significant socio-ecological impacts.

According to a community assessment conducted as part of the research, 68.7% of the respondents reported extreme impacts on fishing, while 65.0% reported extreme impacts on water transport.

During community engagements, residents described how the proliferation of water hyacinth had blocked waterways, disrupted fishing and transportation, affected access to water and created significant challenges for household livelihoods. In some instances, obstructed waterways affected children’s access to essential services.

These experiences provided an important starting point for the research team.

Through different processing methods, the team successfully developed three products from the harvested biomass: a bio-fertilizer, briquettes, and biodegradable sanitary pads.

Water hyacinth transformed into bio-fertilizer

One of the products developed by the researchers was a bio-fertilizer made from water hyacinth biomass.

The process began with harvesting the weed from affected water bodies and shredding the biomass to facilitate processing. The researchers explored biological processing approaches, including composting, vermicomposting and anaerobic digestion, to break down the plant material and release its organic matter and nutrients.

Following processing and curing, the resulting material was developed into an organic soil amendment, providing a productive use for harvested water hyacinth while returning organic matter and nutrients to the soil.

 Briquettes offer an alternative solid fuel

The project team also developed briquettes from water hyacinth biomass, demonstrating its potential as an alternative solid fuel.

The innovation could, with further research, development and appropriate commercialization pathways, contribute to community-based enterprises.

 From water hyacinth fibre to biodegradable sanitary pads

Another distinctive innovation emerging from the research is a biodegradable sanitary pad.

To produce the absorbent material, researchers extracted cellulose-rich fibre from the petioles of water hyacinth and combined it with other locally available plant fibres, including banana fibre and papyrus.

The resulting plant-based material was incorporated into sanitary pads that were subsequently developed and tested to assess their performance as a menstrual hygiene product.

According to the research findings, the water-hyacinth-based pads demonstrated higher liquid absorption capacity and potential health and safety advantages compared with conventional pads. Their use of locally available plant fibres also offers potential to reduce production costs and improve accessibility.

Research generating scientific knowledge

In addition to developing value-added products, the project has generated scientific knowledge on the socio-ecological effects of water hyacinth on affected communities.

The research findings have been published in Scientific Reports, Springer Nature Journal, in a peer-reviewed paper by Nabatanzi, A., Nambejja, C. and Byarugaba, I. (2026) titled “Socio-ecological impacts of water hyacinth (Pontederia crassipes (Mart) Solm) on livelihoods in Katosi Ward, Uganda.”

The study provides evidence of the impacts of water hyacinth on livelihoods, while the wider project demonstrates how the same invasive resource can be investigated as a potential source of useful products.

Other research outputs: Production of personal care and wellness products from different plant materials

Beyond their work on value-added products from water hyacinth, Dr. Alice Nabatanzi and her research team are also translating scientific research into a growing range of locally developed skincare, personal care and wellness products under AURENE AURA, a Ugandan innovation emerging from the Makerere University Plant Sciences, Microbiology and Biotechnology (PMB) Product Development Hub.

Built around the integration of research, nature and innovation, AURENE AURA brings together botanical ingredients and formulation science to develop products designed for diverse skincare and personal wellness needs. The growing collection includes medicated acne-control bars, radiant and brightening soaps and lotions, hypoallergenic goat-milk cleansing bars, moisturizing shower gels, baby-care jelly, lip balms and lip gloss, liquid soaps and other personal-care formulations.

The portfolio also extends to fragrances and botanical perfume mists, herbal respiratory wellness products, and botanical teas and wellness blends, demonstrating the team’s efforts to explore the potential of locally sourced natural ingredients beyond conventional applications.

According to the team, the products are developed through a research-to-product process that involves identifying specific user needs, selecting appropriate botanical and active ingredients, formulation, testing, refinement and packaging. This approach seeks to combine the benefits of botanical ingredients with formulation science, product stability and user safety.

 Research dissemination workshop

Dr. Nabatanzi and her research team presented the findings and innovations to the Makerere University community and key stakeholders during a research dissemination workshop held on 22^nd September 2026 at the Department of Plant Sciences, Microbiology and Biotechnology.

The seminar provided a platform for the team to share the research outcomes, demonstrate the innovations and discuss pathways for translating the findings into practical solutions with environmental, social and economic value.

Remarks from the Chair, MakRIF

Representing the Chairperson of the Makerere University Research and Innovations Fund (MakRIF), Dr. Michael Owor commended the research team for moving beyond documenting the water hyacinth challenge to developing practical innovations with potential community and commercial applications.

He noted that the project exemplifies MakRIF’s mandate, established by the Government of Uganda to support research and innovation that responds to national development challenges.

 “This project exemplifies that mandate by moving beyond describing the problem of water hyacinth to developing practical solutions that communities, enterprises and public institutions can potentially adopt,” he said.

He, however, noted that research findings and prototypes do not automatically translate into sustainable impact, stressing the need for stronger collaboration amongst stakeholders to advance product validation, safety, quality, affordability, regulatory compliance, intellectual property protection and market access.

He urged stakeholders to use the workshop to agree on concrete pathways for advancing the innovations, including further testing, standards development, community-based production, manufacturing and distribution partnerships, and resource mobilisation for scale-up.

Regarding the biodegradable sanitary pads, Dr. Owor stressed the need for sustained engagement with women and girls, schools, health professionals and relevant regulatory institutions to ensure that the product is safe, acceptable, affordable and responsive to the users’ needs.

He further challenged the research team to develop a clear post-project action plan.

“Dissemination should not mark the end of the project; it should serve as a transition from research findings to adoption, enterprise development and demonstrable community impact,” he said.

On behalf of the MakRIF Grants Management Committee, Dr. Owor appreciated the Government of Uganda for its continued investment in research and innovation through the MakRIF, and acknowledged the University Management for providing an enabling environment for the research.

He also recognized the contribution of the participating communities and stakeholders whose knowledge and experiences informed the project.
