New CAES Project to Improve Tea Production in Uganda
Published
3 years agoon

*****Funded by the Danish Fellowship Centre under the Ministry of Foreign Affairs, Denmark, the Project, Nature-based Solutions for Climate-Resilient Tea Production in Uganda (NbS4Tea), is envisaged to sustainably bridge the tea yield gap in Uganda by developing research-based NbS for enhanced climate resilience of tea production systems.

Overview
Tea is a widely consumed and one of the oldest beverages in the world ranked second after water. Reports indicate that in Uganda, tea is the second-largest export crop after coffee, grown by both large-scale (32%) and smallholder farmers (68%). Tea production is increasing in rural areas due to its high demand and associated benefits in the provision of jobs, incomes, and health. The third National Development Plan (NDPIII) 2020/21-2024/25) identifies tea as a key agricultural crop to contribute to the national Vision 2040 of a higher middle-income country with sound food security. Yet, current tea production in Uganda is neither optimal in terms of field management, sustainable intensification, and biodiversity potential, nor climate-resilient under increasingly erratic weather patterns. Farmers in Uganda still grow colonial-era (old) tea varieties that are not climate resilient or properly managed, resulting in low yields of 6 tea hectares per year. Tea production is negatively impacted in yield and quality by climate change impacts on soil quality, disease and pest incidence, drought and heat waves. About 75% of Ugandan soils, upon which 68% of smallholder farmers derive their livelihoods, are predominantly Ferralitic, with excellent physical, but poor chemical properties (low organic matter and nutrient levels, high phosphorus fixing potential). Some farmers circumvent these challenges of soil infertility by applying expensive inorganic fertilizers that consequently pollute the environment and increase greenhouse gas (GHG) emissions. Soil interventions that can sustain the cultivation, productivity, and quality of tea by improving soil fertility are needed. Also, weather variability, increased temperature and erratic rainfall significantly reduce crop yield and tea is no exception. Compared to the 1960s, the temperature in Uganda is expected to increase by 1.8°C by 2050 and rainfall will be more erratic. These abiotic climate stresses act directly and negatively on the tea plants, and increase outbreaks of tea pests and diseases, including arthropods such as mites and mealybugs. Developing methods for detection of plant growth dynamics and stress, improving soil status, and identifying climate-resilient tea varieties resistant to pests and diseases is crucial. There is also a wide knowledge gap in Africa regarding the impacts of the current climate, its variability and expected climate change on tea production systems, especially for smallholder farmers and their sustainability. Bridging this gap can be done by a combination of surveys, modelling, and field experiments.

Fixing the problem through NbS4Tea
A new project by Makerere University College of Agricultural and Environmental Sciences (CAES) in collaboration with NARO, Aarhus University (Denmark), Uganda Tea Association, and Kickstart International is envisaged to address the challenge and improve tea production and productivity in Uganda. Launched by Makerere University Vice Chancellor, Prof. Barnabas Nawangwe on 16th January 2024, the project titled; Nature-based Solutions for Climate-Resilient Tea Production in Uganda (NbS4Tea) will identify and quantify climate change impacts on tea yield and quality in Uganda. Through the project, the research team will identify and recommend climate resilient tea varieties, develop new methods and knowledge on locally available organic resources and NbS, innovate and deploy affordable irrigation technologies, empower vulnerable communities in tea production and processing, and identify export market strategies to substantially increase tea production and productivity in Uganda.

Funded by the Danish Fellowship Centre under the Ministry of Foreign Affairs, Denmark and led by Dr Emmanuel Arthur from Aarhus University, the overall objective of the project is to sustainably bridge the tea yield gap in Uganda by developing research-based NbS for enhanced climate resilience of tea production systems.

Specific objectives:
- The project team will 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, 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.

Expected outcomes and outputs
The expected outcomes tackle both knowledge and tools. These include: (1) Increased tea production, productivity, and biodiversity through the adoption of NbS in an integrated plant-soil management system, (2) Increased research and technical capacity of Makerere and R-ZARDI for (i) irrigation science (ii) remote sensing campaigns and application to tea physiology studies, and (iii) crop simulation modelling, (3) Holistic stakeholder insight on economic feasibility, consumer acceptance and market access strategies, especially for vulnerable groups in the tea value chain, (4) Increased job prospects for youth and women in tea production sub-sectors, (5) Improved social status and increased incomes of tea farmers, traders, and exporters, and (6) Improved economic and environmental quality by recycling biomass waste into value-added products dedicated to soil enhancement. The expected outputs are quantifiable and include: (1) 15+ scientific articles, conference presentations, national reports, and policy briefs informing on climate impact on tea production, resistant varieties, and NbS effects on soil quality, GHG emissions, biodiversity, tea yields and quality, (2) Five PhDs and Five MSc degrees, (3) 4+ high-yielding tea genotypes adapted to drought and heat, diseases and pests, (4) Historical trends and rates in rainfall and temperature changes in major tea-growing areas of Uganda, (5) Future suitability of tea-growing areas in Uganda based on projected climate; Impact of climate parameters on tea production in Uganda, (6) Models for tea net primary production based on canopy reflectance, (7) Model for calculating tea transpiration from canopy temperature data, (8) Chlorophyll fluorescence-based model for identifying most virulent pathogens and effects of disease on resistant tea clones, (9) Catalog of NbS combining agroforestry, mulch-biochar, irrigation and resilient tea varieties to increase biodiversity and tea yield for improved climate resilience of tea farmers in Uganda with documented effects, (10) Smart sprinkler and drip irrigation system with solar-pump, (11) 1 novel climate-smart technology for supplementary irrigation, (12) Co-creation through multi-stakeholder innovation networks for economic feasibility, (13) Market access assessment and empowerment, and (14) Consumers’ valuation of NbS tea from Uganda.

Project team at Makerere
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.

Remarks by the VC
In his address, the Vice Chancellor of Makerere University expressed excitement about the project and pledged Management support towards the realization of the objectives. “The project aligns well with our Strategic Goal 1 that aims to transform Makerere University into a research-led university, responding to national, regional and global development challenges, as well as contributing to global knowledge generation. It also speaks to our goal of increasing graduate enrolment at Makerere, and supports the agro-industrialisation agenda. This is a commendable initiative. As you aim to improve tea production and productivity, you should also plan to transform some to the yields into products that can be commercialised as one of the measures to improve the livelihoods of our people.” The Vice Chancellor appreciated Denmark for the support extended towards various development initiatives at Makerere.

The Principal of CAES, Prof. Gorettie Nabanoga commended the research team, noting that the project is in tandem with the aspirations of the University Strategic Plan (2020-2023) and the CAES Pact for Transformational Change that aims to strengthen research and innovation, and to improve graduate enrolment. “In our bid to contribute to national transformation, we want to ensure that no aspect of development is left behind. We want to form an agenda that will cause transformational change and our focus will be translational research, research that creates positive impact on the lives of our people.”

Laughter, excitement and renewed hope filled the Makerere University Agricultural Research Institute Kabanyolo (MUARIK) on 28th September 2026, as 50 young people who had previously been left out of employment, education and training opportunities gathered to begin their journey under the Africa Climate Collaborative (ACC) Youth Skilling Program.
The youth, selected from Lwengo, Rakai and Yumbe districts, are the first cohort under the Africa Climate Collaborative Youth Skilling Program at Makerere University, an initiative supported by the Mastercard Foundation.
Speaking during the day two orientation at MUARIK, the Program Director, Prof. Gorettie Nabanoga, said the youth will undergo a 10-week residential training programme at MUARIK, followed by a three-month industrial attachment with various organisations.

The youth will thereafter be assessed by the Uganda Vocational and Technical Assessment Board (UVTAB) and will receive government-recognised certificates upon successful completion of the program.
Prof. Nabanoga told the participants that the program was not designed to benefit them alone, urging them to think about how they would use the skills acquired to transform the lives of others in their communities.
“The bigger question is going to be, who is going to benefit because you came here? Don’t think about yourself. Who else?” Prof Nabanoga asked.
She challenged the youth to see themselves as future trainers who would pass on the knowledge and skills they acquire to other young people once they return to their communities.

“The reason you’re here is for us to skill you so that you can go back and skill others. We call you trainers of trainers,” Prof. Nabanoga said.
She encouraged the participants to approach the training with a learning mindset and focus on the skills they could take back home and use to create opportunities for others.
“As you interact, don’t ask what we are going to teach you. But just ask, what are you going to learn for you to be able to go and impact others? What skill are you picking and taking away for you to be able to impact others?” she said.
The Youth Skilling Program is part of Africa Climate Collaborative’s wider eight-year plan to equip 500 young people with practical skills and opportunities that can contribute to employment, entrepreneurship and community development.

Prof. Nabanoga said the 50 participants in the first cohort represent only a fraction of the program’s wider target and challenged them to set the pace for the cohorts that will follow.
The programme also seeks to create a multiplier effect, with each trained youth expected to share their knowledge and skills with others.
She said the ultimate goal is to see the skills translate into businesses, jobs and further training opportunities for other young people.
A section of youth to be supported to start own businesses
Beyond the initial training, Africa Climate Collaborative plans to support young people with promising innovations to develop and scale their ideas.
Out of the 500-youth targeted, 200 will receive support to develop innovations, while 100 will receive further support to establish and scale enterprises in their communities.

For the first cohort, 20 of the best-performing youth with promising innovations will receive support to grow their businesses, while 10 will receive additional support to accelerate and scale their enterprises.
The youths were urged to embrace innovation and strive to develop solutions that can be replicated and scaled.
“I would want to see that the first cohort give me the biggest number of the good innovations that are scalable,” she said.
The Director MUARIK Urged Youth to Turn Skills into Enterprises and Jobs
The Director of the Makerere University Agricultural Research Institute Kabanyolo (MUARIK), whose remarks were delivered by the Director of the Continuing Agricultural Education Centre (CAEC), Dr Christopher Mawa, said the program would equip young people with practical skills in green entrepreneurship, beginning with the poultry value chain, and described MUARIK as more than a farm but a centre for practical learning, research, innovation and enterprise development.

He encouraged the participants to take advantage of the wider learning opportunities available at the institute, including crop production, livestock enterprises, pasture and feed production, farm mechanisation, value addition, agribusiness and environmental management.
“As you begin your training, I encourage you to regard the whole of MUARIK as your classroom,” he said.
Dr Mawa urged the youth to focus on applying the skills they acquire to create enterprises, employment opportunities and solutions within their communities.
“Do not therefore come here simply to complete a three-month course. Come with the mindset of acquiring skills that you can apply. Ask questions. Observe carefully. Participate actively. Learn from the trainers and from one another. Most importantly, begin to ask yourself: “How can I turn what I am learning here into an enterprise, employment opportunity or solution for my community?”.

After 10 Years Out of Education, Africa Climate Collaborative at Makerere University Opens a New Chapter for Okello

For Alex Okello Johan Amoya, a refugee from Zone 5, Bidi-Bidi Refugee settlement, stepping onto the Makerere University Agricultural Institute Kabanyolo (MUARIK) was more than the beginning of a training programme. It was the fulfilment of his childhood dream that had remained out of reach for more than a decade.
As a young boy, Okello dreamed of studying at Makerere University and even remembers singing a song with other children about whether they would ever make it to the university.
Little did Okello know then that the words would follow him into adulthood.
After completing Senior Four (O’level) at Kanyira Senior Secondary School in Yumbe District in 2015, the 33-year-old youth could not proceed to Senior Six (A’ level) and university due to financial difficulties.

For the last 10 years, Okello has been trying different opportunities, but the dream of studying at Makerere remained out of reach, as he did not succeed in getting any scholarship to enable him to progress with his dream.
“My parents could not take me to university. Between secondary school, college and where I am now, it took more than 10 years. I tried different opportunities, but they could not work,” Okello said.
Now, at a stage in life when he had almost resigned himself to the possibility that the dream might never come true, Okello has finally set foot at the university, not as the student he once imagined becoming, but as one of 50 young people selected for the first cohort of the Africa Climate Collaborative Youth Skilling Program.
Okello’s dream, which he once sang about, finally became a reality on 28th September 2026, when he reported to Makerere University Agricultural Research Institute (MUARIK), where he and his other 49 counterparts from Lwengo, Rakai and Yumbe will undergo a 10-week residential training programme, followed by a three-month industrial attachment with various organisations.

The 50 youth, who are the first cohort of the Africa Climate Collaborative Youth Skilling Program at Makerere University, an Initiative supported by Mastercard Foundation will thereafter be assessed by the Uganda Vocational and Technical Assessment Board (UVTAB) and will receive government-recognised certificates upon successful completion of the programme.
The program, supported by the Mastercard Foundation, is providing the participants with practical skills and competences relevant for them to pursue employment, entrepreneurship and other livelihood opportunities.
For Okello, the opportunity has given him new meaning to a dream he had almost given up on.
“I used to dream of reaching Makerere when I was young. Today, that dream has come to pass. I really appreciate all the partners that made it possible for us to be here. I am very sure that this opportunity is here to change my life,” he said.

His dream now extends beyond acquiring skills. Okello plans to return to his community in Yumbe and establish a poultry enterprise specialising in egg production. He sees an opportunity in the limited local supply of eggs, which he says are currently transported from distant areas.
“My dream is to start a poultry business that can supply eggs within my neighbourhood. The eggs supplied there come from far, so I believe this business can make it easier for people to access them while also creating employment opportunities for me and others,” he said.
But Okello hopes the impact of the training will go beyond his own livelihood.
“I also aim to pass the information and knowledge I will receive in this program to others and empower them so that they can also stand on their own. I expect to learn the skills I need and make sure I implement them when I go back,” he said.
A chance to start again
For Jessica Kila-Edward, from Zone 5 of Bidi Bidi Refugee Settlement in Yumbe District, the program represents another kind of new beginning for her.
Jessica completed Senior Four during the COVID-19 period, after which opportunities for further education or employment proved difficult to find.
“Since I completed Senior Four during the Corona season, I had nothing to do. What I could do was farming, but I could not even manage things. Things were really rough for me,” she recounted.

When she learnt about the Africa Climate Collaborative Youth Skilling Program between June and July 2026, Jessica was determined to secure a place.
“I tried all the possible ways to make sure I was part of it, and luckily enough, I succeeded,” she said.
She now hopes to return to her community with skills that will enable her to become a change-maker and support other young people facing similar challenges.
“I am no longer going to be the same person I used to be in the village. I am looking forward to becoming a change-maker in my community and working with other young people who are also crying for opportunities like this,” she said.
Turning skills into income
For Carlos Magimbi from Lwengo District, the program presents an opportunity to strengthen his already existing business in poultry farming while improving his livelihood.
He hopes to use the knowledge gained during the training to support other young people in his community and improve his own income.

“After obtaining the skills from this training, I expect to go back to my community and share them with my fellow youth. I also hope the skills will help me transform my income and improve my life,” Magimbi said.
One of his immediate interests is improving poultry feed production. He says poor-quality feed has affected his birds and hopes the training will equip him with the skills to produce better feed himself. “I am expected to master the techniques, especially because I have been facing a problem with feed. The feed on the market is sometimes of poor quality. I hope that through this training, I can learn how to make my own feed and improve the yields of my birds,” he said.

Mak’s Urban Action Lab Develops Community-Specific Maps to Improve Risk Management in Kampala’s Informal Settlements
Published
4 days agoon
October 6, 2026
In Kampala’s informal settlements, waste, flooding, poor drainage and health risks are closely intertwined. Poor disposal of waste can obstruct stormwater flows, worsening flooding, while stagnant water and blocked drainage can affect health, mobility and livelihoods.
Understanding these connections is at the centre of a community-led systems-mapping process being undertaken through the Urban Futures Project to examine how urban risks emerge, interact and can be addressed.
On 1st October 2026, Makerere University through the Urban Action Lab, convened a community-level systems-mapping workshop to develop a shared understanding of how solid waste, drainage, flooding, climate vulnerability, health, and livelihoods interact within Kampala’s informal settlements.

Rather than examining these challenges in isolation, the exercise explored their interconnections as part of a wider urban system, recognizing that changes in one area can influence outcomes in another.
Putting Community Knowledge at the Centre
Led by Dr. Paul Mukwaya Isolo, Coordinator of the Urban Action Lab, the workshop sought to develop a community-led map of urban risks grounded in the experiences and perspectives of people living and working in informal settlements.
Residents and community leaders from Kampala suburbs, including Kabalagala, Bwaise, Makerere Kivulu and Acholi Quarters, led the process of examining how waste accumulates and moves through their communities, identifying areas vulnerable to flooding, assessing who is most affected and documenting local responses. They also mapped the roles and influence of institutions, service providers, community groups and other actors whose decisions and actions shape these interconnected urban systems, helping to identify key challenges, existing responses and opportunities for community-led action.

The approach recognizes residents as key sources of knowledge about the risks affecting their neighbourhoods. Their lived experience provides insight into where hazards occur, how they disrupt daily life, which groups are most affected and how communities respond. Bringing this knowledge into the mapping process helps ensure that urban risks are understood from the community level and that potential responses build on existing local capacities, priorities and solutions.
Tracing the Waste Management Journey
A key part of the exercise was mapping the movement of solid waste-from generation and sorting through collection, transportation, disposal and recycling-to identify gaps in the waste-management chain that can heighten urban risks.
Participants examined how poorly managed waste can enter drainage channels and waterways, contributing to blocked drainage, flooding and other environmental and public-health risks. They also mapped the roles of informal waste handlers, private service providers, public institutions and communities, highlighting how different actors contribute to the movement and management of waste.

By viewing waste management as part of a wider urban system, the exercise sought to identify opportunities to strengthen waste management services, reduce environmental and public-health risks, and build on existing recycling and resource-recovery practices.
Linking Drainage, Flooding and Livelihoods
The workshop further explored how waste management, drainage and flooding interact within informal settlements.
Participants examined how waste entering drainage channels and culverts can obstruct stormwater flows, increasing the risk of flooding during heavy rainfall, particularly in areas with limited drainage capacity. The flooding can disrupt movement, damage property and businesses, limit access to markets and services, and disrupt livelihoods.

By mapping these connections, participants sought to identify priority risks and inform practical measures to reduce flooding and its effects on livelihoods, while building safer and more resilient communities.
Building on existing community responses
Participants also documented community responses to flooding, waste and other urban pressures, including local practices for managing waste, clearing drainage, coping with floods and protecting livelihoods. The exercise highlighted community knowledge and existing capacities that can inform future, locally driven interventions.
Supporting locally informed urban resilience

The systems-mapping workshop forms part of broader efforts under the Urban Futures Project to advance health equity, inclusive governance and climate adaptation in African informal settlements.
Through the Urban Action Lab, Makerere University is combining research with community knowledge to examine complex urban challenges from the perspective of the people who experience them.

Rather than beginning with predetermined solutions, the process starts by identifying the risks, relationships, actors, vulnerabilities and responses that shape everyday life within informal settlements.
The resulting shared understanding can help communities, researchers, policymakers and other stakeholders identify where action is needed, who needs to be involved and how community knowledge can contribute to healthier, more inclusive and climate-resilient informal settlements in Kampala.
