Mak Researchers in Drive to Improve Waste Management in Uganda

Published

on

****Through a project titled, “Adding value to agro/bio-waste through integrating technologies to enhance sustainable agro-process waste management in Uganda”, the researcher led by Dr Joseph Kyambadde from the Department of Biochemistry and Sports Science, have proposed a number of technologies that can be used to avert the challenge of poor waste management in the country.

Background

Majority of industries in the country such as dairies, abattoirs, breweries, distilleries, and tanneries are engaged in agro-processing. Such industrial processing often leads to the discharge of large quantities of organic-rich wastewater, disease-causing micro-organisms, and greenhouse gas emissions, if poorly treated or managed. While the regulatory body, the National Environment Management Authority (NEMA) requires that all industries should efficiently treat their effluent to meet discharge standards, waste treatment technology market surveys that were carried out in the major industrial cities of Kampala, Jinja, Masaka and Mbarara in 2018 showed that most agro-process industries do not treat their wastewater. Furthermore, very few have in there effluent treatment management, resource recovery processes such as bio-digesters for recovering biogas and nutrient-rich bio-slurry. The industries that attempt to treat their effluent mainly use conventional systems, such as settling tanks and lagoons that do not efficiently remove all waste components. Additionally, industries require energy for their operations, but many use non-renewable sources, such as wood fuel, contributing to deforestation and greenhouse gas emissions. Consequently, the agro-process industries pollute the environment, contaminate drinking water sources, and pathogens from their wastes contribute to cases of diarrheal diseases. The agro-processing sector urgently needs technology solutions that would meet national environment regulatory requirements at affordable costs, but also incorporate resource recovery and reuse to protect the environment and also enhance their profit margins. However, many industries lack cost-effective technologies to convert their wastes into biogas or other useful by-products such as slurry for use as manure/bio-fertilizers. The industries also lack expertise to design and operate appropriate waste treatment technologies.

Addressing participants, the Deputy Principal of CoNAS, Prof. Juma Kasozi called for increased investment into waste management initiatives, noting that it is one of the country’s biggest challenges.

Addressing the challenge of poor waste management

Agro/bio wastes are organic-rich, hence can be biodegraded using appropriately designed integrated technologies. These methods offer the options for meeting national discharge standards, reuse of treated effluent, and recovery of useful by-products. A study conducted by researchers from the College of Natural Sciences (CoNAS), Makerere University in collaboration with partners in the waste management sector proposes a number of technologies that can be deployed to effectively address the challenge of waste in the country. These include; anaerobic-aerobic digesters, sludge drying beds, constructed wetlands, and duckweed growing units.

Through their project titled “Adding value to agro/bio-waste through integrating technologies to enhance sustainable agro-process waste management in Uganda”, the researchers led by Dr Joseph Kyambadde from the Department of Biochemistry and Sports Science at Makerere made several recommendations towards waste management in the country. The researchers called for integration of aspects of the technology, encompassing wastes-to-energy courses/topics in the curricula of programmes like biochemistry, industrial chemistry, and environmental sciences at universities. This would enable training of scientists who would in turn foster adoption and promotion of the developed technologies in different industries. They also emphasized the need to promote investment in technologies that can be used to convert waste into useful by-products like biogas, bio-fertilizers and protein-additives, and to raise awareness about the importance of waste treatment technologies amongst private-public actors, managers/business owners of agro-processing industries, as well as government line ministries/agencies, and development partners.

Research dissemination seminar

On 23rd January 2024, the project team held a seminar at Ridar Hotel, Mukono District to present their research findings/outputs to key stakeholders in the waste management sector such as industry, academia, and policy makers, and also receive feedback. At the meeting, the project PI, Dr. Joseph Kyambadde decried the high level of poor waste disposal in the country. Highlighting the support extended to City Abattoir Traders Development Association (CATDA), Dr Kyambadde said many industries were directly disposing effluent into water sources, posing a number health, environmental and economic risks. “Investing in waste treatment technologies would avert the risks, but also support the recovery of useful byproducts such as nutrient-rich slurry or biogas.” As one of the achievements registered, the project supported the construction of a wastewater treatment plant at Kampala City Abattoir. According Mr. David Mutebi, the PRO of Kampala City Abattoirs Hides and Skin Traders’ SACCO, before Makerere supported the construction of the plant, effluent used to be discharged in Nakivubo Channel, posing several health and environmental risks. Dr Kyambadde appreciated the Government for supporting the project which is envisaged to minimize poor waste disposal throughout the country.

The PI, Dr Patience Tugume at the research dissemination workshop in Namutumba District on 23rd July 2025. Researchers led by Dr Patience Tugume, Department of Plant Sciences, Microbiology, and Biotechnology, College of Natural Sciences (CoNAS) documented 174 medicinal plant species under project “Knowledge, Attitudes, and Conservation of Commonly Traded Medicinal Plants in a Climate-Changing Environment in Eastern Uganda,” funded by Government of Uganda through the Makerere University Research and Innovations Fund (MakRIF), research dissemination workshop, 23rd July 2025, Namutumba District, Uganda East Africa.

Researchers from the Department of Plant Sciences, Microbiology, and Biotechnology at the College of Natural Sciences (CoNAS), Makerere University have highlighted the urgent need to conserve medicinal plants in the face of increasing threats from climate change, over-harvesting, and habitat destruction.

Despite Namutumba District’s rich diversity of medicinal plants, conservation efforts are limited, and several species are already classified as globally and nationally threatened. This highlights the urgent need for focused conservation strategies to safeguard these vulnerable medicinal plants.

Dr Tugume addressing the workshop participants on the key research findings.

Under a project titled “Knowledge, Attitudes, and Conservation of Commonly Traded Medicinal Plants in a Climate-Changing Environment in Eastern Uganda,” a team of researchers led by Dr Patience Tugume documented 174 medicinal plant species. The goal was to assess the existential threats facing these plants due to unsustainable harvesting practices and the lack of effective conservation measures. These species are widely used to treat various health conditions, including malaria, syphilis, diabetes, hypertension, and certain cancers. The findings of the study are intended to guide the development of species-specific, evidence-based interventions to curb possible extinction and loss of medicinal plant resources. The research revealed troubling trends in the availability of key medicinal plants, including:

  1. The herbalists mostly collected their medicinal plants from bushlands (92.0%), markets (82.3%) and wetlands (74.7%) and were rarely cultivated. This is of great concern regarding the conservation and future availability of these resources.
  2. It was noted that 36% of the herbal products were made from roots, which presents a conservation threat since the heavy utilization of roots affects the regeneration of the medicinal plants.
  3. Common plants used were: Kigelia africana (Naibere), Erythrina abyssinica (Ekiyirikiti) and Geranium sauveolens (Lokowe). Kigelia africana was the most cited species by the herbalists, indicating heavy utilization and a high conservation threat if deliberate measures are not taken to ensure its future availability.
  4. Almost all respondents (289, 96.3%) acknowledged a considerable decline in the availability of 13 medicinal plants species including Aloe wollastonii (Ekigagi), Commiphora africana (Nkulidho), Myrica kandtiana (Mukikimbo) and Acacia sieberiana (Mufundawuzi).
  5. Four plant species i.e. Tamarindus indica (Enkoge), Warburgia ugandensis (Balwegira), Mitragyna rubrastipulata (Mutamatama) and Mondia whitei (Mulondo) appear on the Red List of Globally and Nationally Threatened Species and were mentioned among the plants whose population has greatly declined.
  6. The causes of decline in availability of medicinal plants included climate change, overharvesting, agricultural expansion, habitat destruction, land use change and inadequate regulations.
  7. There were no medicinal plant conservation efforts by herbalists.

Participants included leaders of the herbalist associations, traders and research assistants.

The study recommended the following practices to ensure conservation of the medicinal plants:

  1. Promote the use of sustainable harvesting techniques to ensure conservation of medicinal plants.
  2. Conduct capacity building for stakeholders in the medicinal plants sector on conservation, value addition and standardization.
  3. Establish community botanical gardens raw plant collection and sensitization programmes.
  4. Advocate for agroforestry among herbalists to reduce the dependence on natural habitats.
  5. Develop and enforce regulations on accessing natural areas for medicinal plants.
  6. Promote conservation awareness campaigns.

Beyond Being a Dean of Science & Vice Chancellor Emeritus, Prof. Luboobi was a Friend. Just That!

Professor Livingstone Sserwadda Luboobi, Vice Chancellor Emeritus, during his term of office 2004-2009. Makerere University, Kampala Uganda, East Africa.
A Tribute by Assoc. Prof. Arthur K. Tugume, Dean, School of Biosciences, CoNAS. Makerere University, Kampala Uganda, East Africa.
A Tribute by Assoc. Prof. Arthur K. Tugume, Dean, School of Biosciences, CoNAS.

Prof. Livingstone Sserwadda Luboobi, Africa’s Icon of Mathematics is gone. The continent has lost a true giant in the field of mathematics, specifically biomathematics. This dynamic and evolving discipline, which applies mathematical principles to the study of biological systems and phenomena, has been deeply shaped by Prof. Luboobi’s legacy. At Makerere University and across Africa, his influence is etched into the fabric of research, mentorship, and innovation. Prof. Luboobi’s contributions have left lasting marks, on the hundreds, perhaps thousands, of lives he touched directly and indirectly. Each of us carries a unique memory, a lesson, or an inspiration drawn from his life and work. We will dearly miss Prof. Luboobi, a brilliant mind, a generous mentor, and a true icon of African science.

To me and my peers, he was our Dean, Faculty of Science in 1995, and he read-out our names at our graduation in January 1999. Later in 2004 as Vice Chancellor, he signed off my official 4-year PhD study leave in Scandinavia. When the 4 years elapsed before I could complete, we returned to the table and successfully negotiated for extra 2 years of grace which enabled me to complete in excellence in January 2010.

May you rest in eternal peace, Professor. Your legacy continues to inspire
May you rest in eternal peace, Professor. Your legacy continues to inspire

Lately, after his retirement, we found ourselves closely intimate, sharing deeper thoughts on a number of social, development, strategic leadership and governance, and academic matters. As a plant biologist, spending time with a retired Professor of Mathematics, one could wonder what we would possibly have to talk about. And yet, our discussions were rich and thought-provoking. One moment that left a lasting impression on me was his quiet humility. Despite the respect and priority I extended to him, he never assumed entitlement. If he sensed I was busy, he would simply wait outside my office, whether at the Botany Building or my current Dean’s office at CONAS, without interrupting. That gesture spoke volumes.

We often talked about science, and I had much to learn from him. I asked how he had managed to start and sustain the Uganda Mathematical Society (UMS), since we were in the process of setting up the Biology Society of Uganda (BioSU) at the time. I also wanted to hear about his journey – from his undergraduate days to becoming a retired professor. As he shared his story, pausing to catch his breath after long sentences, I sensed he was deeply concerned about something. His concern was that, as of 2017, nearly all senior academics at Makerere University had begun their careers humbly as teaching assistants and risen through the ranks in various disciplines, but that opportunity had since been lost.

He believed that trying to establish a sustainable staffing system without a pool of junior staff, selected directly from the best-performing undergraduate students, was a risky path for the university’s future. With a troubled tone, he said: “I wonder how you people will manage university staffing in the long term when you have removed the foundation…” There were many lessons in that conversation for me.

In October 2023, I started assembling a grant application together with my European and American colleagues (5 Universities) for submission to National Science Foundation (NSF, USA), addressing a certain plant disease conundrum in East Africa. I realized Prof. Luboobi’s expertise in Biomathematics could be relevant. I co-opted him along with another colleague from the Department of Mathematics. I was fascinated at the express knowledge he displayed in modelling biological systems, and in our case, plant disease modelling. Much as his physical strength was less, the intellect was razor-sharp. Even though we didn’t succeed on that attempt, I had numerous other lessons to learn from his seniority.

We shared personal stories. I re-learnt that living simple as much as possible helps a lot. Although this was not new, hearing it from one you respect takes on a whole new meaning. If I died today, I wonder what my peers or junior colleagues would say about me? I would not hear it, though. I am happy I had chance to tell Prof. Luboobi what he meant to me when he was still alive.

I regret his death. We usually say it is untimely, but will death of a loved one ever be timely? Holy Scripture says, Seeing his days are determined, the number of his months is with You; You have appointed his bounds that he cannot pass.” – Job 14:5. This is an emphasis of God’s sovereignty over life and death, highlighting that He determines the length of a person’s life and sets unchangeable limits, just as He does in setting boundaries and limits for all His creation. Prof. Luboobi could not cross the boundary set by the creator.

I am grateful that the Principal, College of Natural Sciences (CoNAS), Makerere University and his team did their best to mobilize support at the most critical moment of need. I am grateful to God for gifting Makerere University with Prof. Luboobi, and for allowing me in particular a chance to walk a little close with him in his evening days of his life between 2023-2025.

Good bye Prof. Livingstone S. Luboobi! Go and serve God with the angels. We will also join you, in the course of time! See you later when that time comes!
