****Funded by the Danish Fellowship Centre under Denmark’s Ministry of Foreign Affairs, NbS4Tea is a five-year initiative aimed at enhancing climate resilience and tea productivity in Uganda.

Launch of drones for data collection

The Nature-based Solutions for Tea (NbS4Tea) project has registered a significant milestone with the successful deployment of drones to improve environmental and agricultural data collection.

On 19^th June 2025, the project team officially launched the drones at the Rwebitaba Tea Research Centre in Kyenjojo District, the project’s main research hub. The launch event included hands-on training sessions by Mr. Timothy Mutungi, a certified Remote Sensing Drone Pilot. Mr. Mutungi provided detailed instruction on drone operation, safety procedures, and data acquisition techniques specifically tailored to the project’s goals. The training was attended the core NbS4Tea researchers as well as students supported by the project.

By utilizing drone technology, the team will be able to capture high-resolution imagery and gather critical environmental data across vast tea-growing areas. This will enable more precise assessments of biodiversity, soil health, water use, and overall ecosystem services. The valuable insights generated will guide the development of sustainable, nature-based agricultural practices with the potential for widespread adoption throughout the tea industry.

About the NbS4Tea Project

NbS4Tea is a five-year initiative aimed at enhancing climate resilience and tea productivity in Uganda. Funded by the Danish Fellowship Centre under Denmark’s Ministry of Foreign Affairs and led by Dr Emmanuel Arthur from Aarhus University, the project is being implemented through a consortium of Ugandan and Danish institutions namely: Makerere University, the National Agricultural Research Organization (NARO), Uganda, Uganda Tea Association, Aarhus University, Denmark, and Kick-start International.

The primary objective of the project is to sustainably close the tea yield gap in Uganda by developing research-driven, nature-based solutions that enhance the climate resilience of tea production systems. This involves identifying climate-resilient tea varieties, integrating tea prunings and banana by-products, utilizing nitrogen-fixing agroforestry trees, and improving irrigation management. The approach emphasizes socio-economic feasibility, capacity building in research, and a market-oriented, multi-stakeholder collaboration to ensure both environmental and economic sustainability.

At Makerere University, the project is coordinated by Dr Alex Nimusiima from the Department of Geography, Geo-Informatics and Climatic Sciences at CAES. Other Project members are; Dr Grace Nakabonge from the Department of Forestry, Biodiversity and Tourism; Dr Prossy Nakawuka from the Department of Agricultural and Bio-systems Engineering; Dr Twaha Ali Basamba from the Department of Agricultural Production; and Dr Alice Turinawe from the Department of Agribusiness and Natural Resource Economics.

Specific objectives

1. Identify and quantify climate change impacts on tea yield and quality based on historical and newly obtained data and novel data mining methods.
2. Screen, select and recommend tea varieties adapted to abiotic (drought and heat) and biotic stresses (diseases and pests).
3. Develop new knowledge on the potential of local waste biomass (tea prunings, banana pseudostems and peels) as soil amendments- mulch, compost, biochar, to recycle nutrients, improve soil fertility, increase carbon sequestration and alleviate drought.
4. Reveal NbS through agroforestry combined with organic mulch, irrigation and resilient tea varieties that increase biodiversity and tea yield.
5. Innovate new methods to enhance tea production under climate change through rainwater harvest and climate-smart irrigation infrastructure.
6. Empower vulnerable groups (women, youth, and people with disabilities) in tea production and processing to ensure multi-actor involvement and socio-economic benefit outreach of the proposed NbS in tea cultivation and production.
7. Identify export market strategies for NbS tea products, aligned with consumer preferences.

The Directorate of Graduate Training is rolling out the Research Management Information systems (RIMS) to efficiently and effectively monitor the academic progress of all graduate students.

“RIMS will be used to track efficiently every stage of activity of graduate studies from course works, research concept to thesis completion.” The Director of Graduate Training, Prof. Julius Kikooma said.

He added, “The RIMS team is here to share developments on the system that are designed to support the agenda of Makerere university. When graduate students enter a given chapter of their research works, their supervisors will automatically receive mail prompts to swiftly handle, give comments and guide the students on the way forward.”

During the roll out training recently at the College of Health Sciences in Mulago, Prof. Kikooma said, “The Directorate of Graduate Training is working in collaboration with Directorate of Innovation, Research and Partnerships (DIRP) and the Directorate of Information Communication and Technology Support (DICTS) to ensure a smooth training to all the schools and colleges. Digitalising the graduate management process is anticipated to increase the number of graduate admissions and completion in the long run.”

“As the three directorates, we sat and reviewed the university graduate strategy and policies around it. We got reviewed policies and procedures approved by the University Senate last year. We no longer have provisional admission letter requirement for our PhD students. It is now full admission straight away and we follow a cohort system of admission for the PhD by research students.” He added.

RIMS is a version of how the Directorate of Graduate Training aims to handle the process of systematic tracking of every point of progress in the entire academic journey of graduate students.

The Directorate of Graduate Training has so far conducted the RIMS training at three Colleges namely; College of Health Sciences (CHS), College of Business and Management Sciences (COBAMS) and College of Natural Sciences (CONAS).

The critical stakeholders on the RIMS value chain include Heads of Departments, College Principals and Deputy Principals, Directors, School Deans, Supervisors as well as Graduate coordinators. “All the above are key actors and must be able to use RIMS in the graduate process, capturing all profiles of students and supervisors and should be able to use it appropriately.” He emphasized.

He said that RIMS will bring all stakeholders on the same page and will be able to adequately troubleshoot any hinderance to progress when course works are done, to dissertation and thesis completion. Makerere university target is to increase its graduate students’ enrollment from 19% to at least 30% in the next five years.

Prof. Bruce James Kirenga, Principal College of Health Sciences welcomed RIMS training saying that this kind of E- learning and supervision tracking is the way to handle graduate studies as it seems to reduce the turn around time for student- supervisor responses.

“Every activity in the graduate students learning journey is monitored swiftly. Whatever the students upload on to the system, supervisors get message pop-ups on their mails, review the works immediately and attach comments for the students to appreciate and manage appropriately.” He said.

Prof. Kirenga added that the audit trail created under RIMS will provide good progressive academic reports and improve the journey to Doctoral studies.

“Heads of Departments are able to see all students in the department, any pending system approvals, observe completion rates and total progressive over view of each student and that the total overview of department performance will be clearly seen under RIMS.” He added.

Dr. Robert Kalyesubula – the Chair. Dept of Physiology, Makerere University College of Health Sciences said RIMS will improve the efficiency of supervisors while handling the graduate students.

“RIMS views all documents and proposals of students. We will be able to observe which supervisor takes long to respond, the number of days they have taken to respond and how long an issue has pended undone at a certain level.”

A groundbreaking symposium exploring the role of insects in African farming systems concluded on June 6^th, 2025, at Onomo Hotel in Kampala. Convened by Makerere University’s College of Veterinary Medicine, Animal Resources and Biosecurity (CoVAB) in collaboration with Michigan State University (MSU), the event drew participants from over ten countries, including researchers, development experts, regulators, and practitioners.

Under the theme “Advancing the Role of Insects in African Farming Systems for Feed, Food, and Food Security,” the two-day gathering aimed to share knowledge and experiences on integrating insects into food and feed systems to address food security challenges across the continent. The discussions revolved around four key sub-themes namely; Insects as animal feed to promote sustainable livestock production and livelihoods; Insects for human food and food security, including indigenous insect-based diets; Insects for improved soil health and crop production and Commercialization of insect farming, with a focus on regulation and standardization.

The symposium commenced with opening remarks delivered on behalf of Makerere University’s Vice Chancellor, Prof. Barnabas Nawangwe, by his representative, Prof. Frank Norbert Mwiine, Principal of CoVAB. He welcomed participants and commended Dr. Deborah Amulen, Lecturer at CoVAB and chief convener, for organizing a well thought out event. He emphasized that the symposium would not only raise awareness of the role of insects in Uganda’s and Africa’s socio-economic development but also help place insects on the agenda for broader discussions and integration into food security strategies.  He said the event served as a platform for knowledge exchange, highlighting the untapped potential of insect farming in transforming food security, sustainable agriculture, and economic growth.

Key facilitators at the symposium were esteemed experts from leading institutions worldwide, who shared their insights on insect-based food systems and sustainable agriculture. Among the distinguished speakers were Prof. Jeffrey K. Tomberlin from Texas A&M University, Prof. Eric M. Benbow from Michigan State University, Prof. Florence Dunkel from Montana State University, Dr. Denise Beesigamukama, a Postdoctoral Fellow, ICIPE Kenya and Dr. Deborah Amulen the host from Makerere University. These are exemplified in their contribution towards academic research and leadership, policy and industry impact and more importantly their expertise in insect science.

During the deliberations, the experts emphasized that insects offer a viable, sustainable, and nutrient-rich solution to Africa’s growing food demands. The event underscored ongoing research and commercialization efforts aimed at mainstreaming insect farming into the agricultural sector. As global interest in alternative protein sources continues to rise, the symposium marked a significant step toward harnessing the potential of insects to enhance food security in Africa.

Experts underscored that Africa is home to over 470 recognized edible insect species, providing a rich source of proteins, fats, and essential micronutrients. Insects have historically been a staple in diets across Uganda, Southern Africa, and other regions, serving as a vital food source in times of drought, conflict, and food scarcity. One of the most discussed innovations at the event was the large-scale farming of Black Soldier Fly, which is being utilized to produce not only the larvae but also frass, a high-protein animal feed and organic fertilizer to enhance soil health and boost agricultural yields.

Several scholars presented their research in the area of Insects, where together with the farmers, industry representatives, policy makers and practitioners contributed valuable perspectives on advancing the role of insects in food security, animal feed, and ecological sustainability in Africa. Their discussions underscored the importance of research, policy, and commercialization in expanding insect farming across the continent.

One of the keynote discussions highlighted Uganda’s rich tradition of consuming insects as part of its food culture, reinforcing their significance in nutrition and sustainability.  Participants shared insights on local insect consumption practices and their role in livelihoods, drawing from countries like Cameroon, Malawi and many others represented at the event. The forum also featured representatives from key institutions, including the National Council for Science and Technology and The National Agricultural Research Organization (NARO) which contributed perspectives on research, policy development, and commercialization of insects as sustainable food sources, the Ministry for Agriculture, Animal Industry, and Fisheries (MAAIF), emphasizing the Ugandan government’s support for insect farming initiatives.

The Kenya based scientific research institute, the International Centre of Insect Physiology and Ecology (ICIPE) played a key role in the discourse and exhibited several innovations arising from research and their work in insects. Experts explored how insects can revolutionize animal feed production, providing an affordable, high-protein alternative to conventional sources.

With global attention shifting toward alternative and sustainable food sources, experts stressed the need for policy standardization and enhanced investment in insect-based food systems across Africa. During the event, MAAIF announced a $325 million investment through a six-year Smart Agriculture Transformation Project, aimed at expanding sustainable farming practices, reducing environmental impact, and increasing food security through alternative protein sources.

The symposium reaffirmed Africa’s position at the forefront of insect farming research, with discussions centered on scaling production, improving regulation, and leveraging indigenous knowledge for food security solutions. Moving forward, participants emphasized the importance of quality control, standardization, and policy frameworks to ensure safety, scale production, and boost market competitiveness. With Uganda leading discussions on alternative protein sources, the symposium laid the foundation for future innovations in agriculture.
