1 year agoon

****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 19th 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
- Identify and quantify climate change impacts on tea yield and quality based on historical and newly obtained data and novel data mining methods.
- Screen, select and recommend tea varieties adapted to abiotic (drought and heat) and biotic stresses (diseases and pests).
- 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.
- Reveal NbS through agroforestry combined with organic mulch, irrigation and resilient tea varieties that increase biodiversity and tea yield.
- Innovate new methods to enhance tea production under climate change through rainwater harvest and climate-smart irrigation infrastructure.
- 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.
- Identify export market strategies for NbS tea products, aligned with consumer preferences.

Introduction
Makerere University, through the Departments of Animal and Range Sciences and Extension and Innovation Studies (CAES), in collaboration with the National Agricultural Research Organization (NARO), specifically the Mbarara Zonal Agricultural Research and Development Institute (MbaZARDI) and Mukono Zonal Agricultural Research and Development Institute (MuZARDI), Bukalasa Agricultural College, Ghent University, KU Leuven, and HOGENT, has secured VLIR-UOS TEAM 2026 funding for the project “Agroforestry-dairy integration for sustainable agri-food systems in peri-urban and rural Uganda.”
The project aims to strengthen the Ugandan–Flemish partnership in validating and promoting agroforestry-based feeding strategies for crossbred dairy systems in peri-urban Kampala (zero-grazing) and the Southwestern cattle corridor (paddock systems). To support this work, applications are invited from eligible Makerere University and NARO staff for two PhD positions.
PhD Position 1: Physiological validation of tree-based, nutrient-specific feeding strategies in crossbred or exotic dairy systems
Research focus: This PhD will evaluate the physiological and production responses of crossbred/exotic dairy cows to tree-based, nutrient-specific feeding strategies under peri-urban zero-grazing systems around Kampala and paddock systems in the Southwestern cattle corridor.
Building on previous studies that identified nutrient deficiencies and promising tree-based feed resources, the research will assess the effectiveness of locally formulated supplements in improving the productivity of early-lactating crossbred dairy cows across contrasting production systems and seasons. Blood profiling and production monitoring will be integrated to evaluate animal responses. The PhD will be jointly supervised by Makerere University, NARO and Ghent University.
PhD position 2: Socio-economic feasibility and adoption of agroforestry-based dairy feeding strategies
Research focus: This PhD will investigate the socio-economic feasibility and adoption of agroforestry-based feeding strategies in mixed crop–livestock systems. Using a mixed-methods approach, the study will combine household surveys, stakeholder interviews and gender-segregated focus group discussions to evaluate the adoption of fodder and multipurpose trees.
The research will compare existing tree use with new planting options, assess economic viability, labour requirements, land constraints, gender roles, market access and knowledge systems, and identify factors influencing adoption under contrasting dairy production systems. Comparisons between peri-urban Kampala and the Southwestern cattle corridor will provide evidence on scalability and inform policy and extension strategies.

Africa Climate Collaborative at Makerere University Launches Youth Skilling Program to Catalyse Enterprise Development
Published

Mak Editor
By Damali Mukhaye
The Africa Climate Collaborative at Makerere University, an initiative supported by the Mastercard Foundation, has launched an inclusive Youth Skilling Program aimed at equipping young people with practical, market-driven skills to unlock business opportunities and contribute to climate resilience.
The Program will begin with a pilot of fifty (50) youth selected from Lwengo, Rakai and Yumbe districts, forming the first group of a planned 500 young people to be trained over the eight-year implementation period. The initiative targets youth who have completed at least Senior Four or its equivalent but have not enrolled for or completed university education.
For the first group, the youth will receive intensive hands-on training across the poultry value chain, enabling participants to develop climate-smart enterprises, create employment opportunities and strengthen their livelihoods.
The Program Director of the Africa Climate Collaborative, Prof. Gorettie Nabanoga, indicated that the Skilling Program was designed in response to the challenges faced by thousands of young people who are not in employment, formal education or vocational training (NEET).
“We realised that there are several young people who never got an opportunity to attend university or pursue higher education, yet they constitute the majority of our population. We are intentionally creating pathways that enable them to acquire practical skills, participate meaningfully in the economy and secure dignified employment,” Prof. Nabanoga said.

Applications for the first group under youth skilling program are now open to eligible youth residing in either Lwengo Sub-County in Lwengo district, Ddwaniro Sub-County in Rakai district, Zone 5 of the Bidibidi Refugee Settlement, or Ariwa Sub-County in Yumbe District.
Prof. Gorettie Nabanoga explained that the Africa Climate Collaborative deliberately selected these locations because they are among the most vulnerable to the impacts of climate change.
The programme prioritises districts within Uganda’s agropastoral landscape. She further indicated that the Program is aimed at nurturing young people who will serve as catalysts for enterprise development within their communities.
“The training will equip participants with practical skills that enable them to innovate around climate-related challenges while protecting the environment. Ultimately, they will generate income, improve their livelihoods and become catalysts for local economic transformation.” she said.
Why Poultry?
The Africa Climate Collaborative selected the poultry value chain as the entry point for the pilot because it offers diverse opportunities for entrepreneurship, innovation and employment.
According to Prof. Nabanoga, trainees will specialise in different components of the value chain, including feed production, hatchery management, poultry production, poultry product value addition and poultry waste management.
“The poultry sector offers numerous opportunities for innovation. By developing expertise across different components of the value chain, these young people will collectively strengthen the entire poultry ecosystem.”
Environmental sustainability remains central to the program. Participants will be introduced to climate-smart production practices, resource efficiency and innovative approaches to poultry waste management that minimise environmental impacts while improving productivity.
Program participants are expected to become community resource persons who will transfer the acquired knowledge and skills to other young people.
“These young people will become trainers of trainers. When they return to their communities, they will establish enterprises and mentor others, creating a critical mass of youth engaged in climate-smart businesses.”She noted.
District Leaders and Experts Welcome the Initiative
District leaders have welcomed the program, describing it as a timely intervention for addressing youth unemployment.
Francis Bwowe, Senior Agricultural Officer for Rakai District, described the intervention as timely and transformative.
He noted that the closure of Primary Teachers’ Colleges and the increasing costs of post-secondary education have left many youths without viable alternatives.
“Many young people who complete Senior Four have nowhere to go. Therefore, a program that equips them with practical skills to start their own businesses is extremely important. We believe it will help them become self-reliant and earn a living,” he explained.
Community leaders also expressed optimism about the program’s potential to transform livelihoods.
Mr. George Kizito, LCII Chairperson of Kalere Parish in Rakai District, said unemployment remains one of the greatest challenges facing young people.
“The opportunities exist, but many young people lack the capacity and confidence to create jobs for themselves. In our community, people involved in poultry farming are earning good money, but many youths simply watch because they do not know where to start from,” he said.
The program has also received positive reactions from technical experts. Responding through one of the Africa Climate Collaborative’s social media platforms, Ms. Nehwera Eufemia, a specialist in animal feeds, commended the decision to prioritise feed production.
“Feed accounts for nearly 70 percent of poultry production costs and is the single most important factor influencing profitability. Strengthening skills in feed production provides a strong foundation for improving productivity and sustainability across the entire poultry value chain” she observed.
Ms. Eufemia encouraged eligible young Ugandans to apply and take advantage of the opportunity.
Who Can Apply?
Applications are open to young people residing in:
- Lwengo Sub-county, Lwengo District;
- Ddwaniro Sub-county, Rakai District;
- Zone 5, Bidibidi Refugee Settlement; and
- Ariwa Sub-county, Yumbe District.
Eligible applicants must have completed at least Senior Four (O-Level) or its equivalent but should not have enrolled for or completed university education. Applicants must also be between 18 and 35 years of age by the application deadline and should not be engaged in any form of formal employment or training.
Young women, young mothers, refugees and persons with disabilities are strongly encouraged to apply.
