New CAES Project to Improve Tea Production in Uganda
Published
2 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.

October 28, 2025
By Betty Kyakuwa and Eve Nakyanzi
Makerere University will from 28th to 30th October 2025 host the International Conference and Training Workshop on Food Systems Transformation for Climate Actions (ICTW-FSTCA 2025) under the COMSTECH Forum for Environment and Ecosystem Restoration (CFEER). COMSTECH is the Standing Committee for Scientific and Technological Cooperation, one of four standing committees of the Organisation of Islamic Cooperation (OIC) dedicated to the promotion and cooperation of science and technology activities among the member states.
Speaking at the opening ceremony on 28th October, the High Commissioner of Pakistan to Uganda, H.E. Muhammad Hassan Wazir, commended Makerere University and COMSTECH for convening discussions on such a timely and relevant theme. Emphasising the urgency of collective action, he remarked, “Climate change is real. While the whole world has been feeling its impact for several years, we in Pakistan witnessed devastation. We recently experienced a large-scale cloud burst, severe flood, flash flooding and melting of the glaciers in the Himalayas.”

H.E. Wazir noted that such experiences reveal the deep vulnerabilities of global food systems and the need for coordinated solutions. The High Commissioner also applauded Uganda’s progress in infrastructure and economic stability, describing it as an attractive environment for investment and collaboration. He reaffirmed Pakistan’s commitment to work closely with African countries—particularly Uganda—in areas such as agro-processing, water-saving irrigation technologies, and climate-resilient crops, as part of the “Look Africa Policy”, an initiative launched in 2018 to strengthen bilateral and multilateral cooperation between Pakistan and the African continent.
In his welcome address, the Vice Chancellor of Makerere University, Prof. Barnabas Nawangwe, emphasized the importance of universities in addressing Africa’s pressing food security challenges amid high population growth and climate change. He highlighted Makerere’s century-long legacy of academic excellence, innovation, and contributions to regional development, including breakthroughs in medicine, agriculture, and technology. Prof. Nawangwe underscored the university’s commitment to research, innovation hubs, and youth entrepreneurship as key solutions for building resilient and sustainable food systems, and expressed hope that the knowledge shared at the workshop would benefit educators, students, and farmers alike.

In his keynote address, Dr. Logan Cochrane, Dean of the College of Public Policy at Hamad Bin Khalifa University (HBKU) Qatar, outlined the pressing challenges and promising opportunities shaping global food systems today. He noted that climate change is creating new public health risks, such as malaria spreading to areas that had previously been unaffected, while also disrupting agricultural productivity. Equally concerning are shifts in global diets: more people are consuming processed, salty, and fatty foods, resulting in an unprecedented situation where, in 2025, as many children are overweight as are underweight—approximately 10% of the global population in each category. This dual challenge, he observed, underscores that food systems are not only insufficient but increasingly unhealthy. Dr. Cochrane also highlighted structural vulnerabilities, including overreliance on global food trade, limited irrigation, poor road networks, and inadequate access to markets, hospitals, and schools as factors that reduce the African continent’s efficiency and resilience.
Despite these challenges, Dr. Cochrane emphasized optimism and actionable opportunities. He shared that sustainable local production, especially of regionally relevant crops like Ethiopia’s taro and false banana, can improve nutrition and domestic food security. Strengthening regional trade networks, particularly through initiatives like the African Continental Free Trade Agreement, presents a US$50 billion opportunity for Africa to reduce dependence on imports.

He added that Governments can play a transformative role by enabling smallholders and the private sector through infrastructure improvements, policy support, and food reserve systems. Reducing food loss and waste, which can reach up to 50% from farm to kitchen, he noted, is another key area for efficiency gains. Furthermore, he said that social protection programs, early warning systems for pests and diseases, and school-based nutrition initiatives can safeguard vulnerable populations while supporting farmers’ livelihoods.
Finally, Dr. Cochrane highlighted the need to make agriculture “cool” for young people, by integrating technology, circular food systems, and innovative approaches to attract the next generation to agricultural careers. By leveraging these opportunities, he argued, food systems can become healthier, more resilient, and more sustainable for the future.

Mr. Alex Bambona who represented the Permanent Secretary, Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) highlighted Uganda’s commitment to the global food systems transformation agenda. He noted that in September 2021, Uganda joined international efforts to address food security and recognized several challenges in fully harnessing the country’s natural endowments. “Uganda is a beautiful country, gifted by nature, and has the potential to feed not only East Africa but much of the continent,” he said. However, he stressed that gaps remain, particularly in the application of science and technology to transform agriculture. Mr. Bambona also identified climate change as a significant challenge, acting as a negative driver that must be addressed for Uganda to realize its full potential in sustainable food production.
Ms. Angela Atukunda, representing the Secretary General of the Uganda National Commission for the United Nations Educational, Scientific and Cultural Organization (UNESCO)/ Islamic World Educational, Scientific, and Cultural Organization (ICESCO), highlighted Uganda’s longstanding engagement with international cooperation through its membership in the OIC since 1974, which also brought the country into ICESCO. She explained that UNATCOM, as Uganda’s National Commission for UNESCO/ICESCO, plays a key role in promoting science, innovation, education reform, and cultural heritage preservation in collaboration with government ministries, academia, civil society, and international partners.

Ms. Atukunda emphasized that platforms provided by events such as ICTW-FSTCA 2025 are crucial for sharing knowledge, shaping policy, and building partnerships to address urgent climate action needs through food systems transformation. She noted that globally, food systems account for nearly one-third of greenhouse gas emissions, and without reform in production, processing, transport, and consumption, efforts to limit global warming will fall short.
She further noted that climate change is already threatening food security through unpredictable rainfall, soil degradation, droughts, floods, and pests—impacts that disproportionately affect smallholder farmers. She stressed the importance of climate justice and the development of homegrown solutions rooted in science, indigenous knowledge, innovation, and inclusive governance.

The opening ceremony held in the Senior Common Room, Main Building was virtually addressed Coordinator Genera, OIC-COMSTEC-H.E. Prof. Dr. Iqbal M. Choudhary and the Advisor/Director, Science and Technology, ICESCO-Dr. Muhammad Sharif. ICTW-FSTCA 2025 will feature a number of discussion and working sessions on Day 1 and Day 2 and conclude on 30th October with a filed visit to the National Crops Resources Research Institute (NaCRRI) in Namulonge and the Makerere University Agricultural Research Institute Kabanyolo (MUARIK).

RUFS Empowers Smallholder Farmers to Build Resilience against Floods & Droughts
Published
2 weeks agoon
October 24, 2025
Smallholder farmers across the globe are increasingly confronted with the dual challenges of water-related stresses, ranging from devastating floods to prolonged droughts. These cyclical extremes threaten livelihoods, food security, and sustainable agricultural productivity. To effectively address these challenges, it is essential to implement resilient, integrated strategies that recognize the complex and fluctuating nature of water availability.

The Resilient Urban Food Systems (RUFS) project promotes innovative approaches that empower smallholder farmers to better manage water resources by capturing and storing excess water during periods of abundance, efficiently utilizing limited water supplies during dry spells, and building adaptive capacity to withstand and recover from extreme weather events. Through these solutions, RUFS helps create a foundation for sustainable farming that not only mitigates risks but also enhances productivity and long-term resilience in vulnerable agricultural communities.

Under the initiative titled “Strengthening Urban Food Systems Resilience to Flood and Drought Risks through New Strategic Partnerships: Consolidating Gains from the RUFS Project in Kasese Municipality and Mbale City, Uganda,” the team conducted an intensive two-day training workshop for smallholder farmers in Kasese Municipality. The workshop aimed to equip farmers with practical skills and knowledge, specifically in the production of organic pesticides and fertilizers, to enhance their adaptive capacity.

Conducted on 13th and 14th October 2025 at the residence of Bishop Stephen Nsibambi on Kilembe Road, Kasese Municipality, the training built upon insights and outcomes from the inception meeting of the RUFS Phase II held 18th–21st August 2025. The initiatives under Phase II of the RUFS Project aim to reduce damage from natural hazards, improve drainage and water storage, conserve soil moisture, decrease reliance on rainfall, and ultimately bolster resilience against water-related extremes.

The project is led by Prof. Frank Mugagga from the Department of Geography, Geo-Informatics, and Climatic Sciences at Makerere University, and funded through the AgriFoSe2030 Programme.

Achievements Registered from the Workshop
The training enhanced the resilience of smallholder farmers by equipping them to better withstand natural hazards, with a special focus on reducing their vulnerability to floods and droughts. The two-day workshop concentrated on the production and use of pesticides and fertilizers derived from locally available, nutrient-rich plants such as Tithonia (Kimyula), Wandering Jew (Naanda), Amaranthus spp. (Ddodo), Black Jack (Sere), and Phytolacca (Luwoko). It also covered the use of ash, animal and human urine, as well as techniques for harvesting and purifying rainwater.

Specifically, smallholder farmers in Kasese Municipality gained practical skills in the production of natural, effective plant teas using decomposing and hairy plants combined with ash, an eco-friendly method to enrich soil sustainably. They were trained in rainwater harvesting through trench digging and other methods, as well as rainwater purification using charcoal. Additionally, the farmers were taken through the process of producing fertilizers using a mixture of cowdung, water and ash, as well as human urine and locally available plants. Furthermore, farmers learned to make organic pesticides from readily available materials such as ash, animal urine, onions, papaya leaves, water, pepper, and soap.

Overall, the training promoted sustainable, eco-friendly farming practices while strengthening smallholder farmers’ skills in pest management and climate-resilient agronomic techniques. It was led by Mr. Henry Stanley Mbowa, Head of Research at AidEnvironment and a member of the RUFS Project.
Insights from the farmers’ representative
Mr. Sunday Salveri, a dedicated smallholder farmer from Kasese, highlighted the critical role of active farmer participation in forming and sustaining a farmer group and association. In his address, he urged fellow farmers to become more engaged and take proactive steps to improve their livelihoods through active group participation. He emphasized that increased involvement is essential for maintaining a vibrant, effective group that benefits all members. Mr. Salveri also encouraged more farmers to join the group, viewing collective effort as key to achieving economic sustainability. “Expanding membership is vital for the association’s growth and resilience,” he noted.

Furthermore, Mr. Salveri stressed the importance of applying practical business lessons learned on the ground. He suggested that farmers produce fertilizers and pesticides themselves as a way to both generate income and reduce costs for members. To facilitate knowledge sharing and skill development, he proposed establishing a demonstration site to train other farmers. Recognizing the role of family support, Mr. Salveri emphasized involving family members in these activities, highlighting that their participation is crucial for the long-term success and sustainability of agricultural endeavors.
He underscored the need to think beyond agriculture, advocating for the continued existence of the cluster and the RUFS initiative. He expressed hope that these efforts will bring sustained benefits to farmers and their families.
