Project Overview

Coffee and bananas are key crops in eradicating extreme poverty and hunger as well as ensuring environmental sustainability in Uganda. However, production of both crops is far below the attainable yields, mainly due to abiotic (soil, water, temperature) and biotic (pests, diseases, weeds) stresses. Modern research has identified integrating shade trees in coffee-banana systems as the entry point for re-establishing productivity of both crops. However, prior to this project these systems had not yet been fully quantified. There were no recommendations on how (or if) to intercrop with regard to optimal planting arrangements; shade management regimes; and best soil, water, and crop management options.

This PEER project explored the best coffee-banana agroforestry combinations to identify the optimal trade-offs in food, income, risks, and environmental sustainability. Specifically, the research characterized existing coffee-banana agroforestry systems; identified biotic and abiotic constraints, including farmers’ coping strategies; generated an improved Integrated Crop Management package; developed advocacy and lobby tools that can strengthen the value chain; and developed capacity for research and promote synergies among actors along the value chain. Overall, the project sought to improve agriculture and sustainable environmental management in Uganda, aiding adaptation to climate change. In the long run, this information could be scaled up to other farmers in the Lake Victoria region with similar farming systems.

Final Summary of Project Activities

Team members created and conducted diagnostic surveys in five major coffee-producing regions of Uganda to characterize existing coffee-banana agroforestry systems and identify the major biotic and abiotic constraints. In each region, 10 districts were selected at random and in each district, 10 households selected randomly were sampled and data collected on their farms. Results showed diverse cropping systems, including coffee as a mono-crop, banana as a monocrop, coffee-banana intercrop, and coffee-banana-shade trees inter-crop, as well as different kinds of coffee growing.

PEER researchers combined farmers’ knowledge and information on regional tree species to make recommendations for appropriate shade trees for the various coffee growing regions and highlight “bad neighbor” trees for coffee and bananas. Among the biotic constraints, farmers reported weeds, particularly couch grass and annual broad-leaved weeds, as well as pests and diseases; particularly the black coffee twig borer (BCTB) for coffee and banana bacterial wilt (BBW) for bananas. Farmers also reported declining soil fertility, limited moisture, soil erosion, and an assortment of socioeconomic constraints, including lack of capital; limited and unaffordable labor, input, and output markets; and several gender-related issues. Most farmers were also aware of climate change and its effects, particularly, prolonged drought and poor yields in both coffee and bananas. At least 50% of the farmers interviewed reported that they plant trees as an adaptation to climate change. Limited space and lack of seedlings were reported as the major reasons hindering farmers from planting more trees.

Researchers conducted follow up studies in the surveyed regions, collecting samples of major pests and diseases of coffee and banana trees. Regional differences in the prevalence of inspect pests were identified and used to update the existing Integrated Pest Management (IPM) package for the twig borer. Media (print and electronic) and farmer-to-farmer communication approaches were the most important sources of agricultural information for the farmers. However, access and use of agricultural credit facilities is still very low in Uganda.

The team used the project results to generate training materials, posters and manuscripts for the farmers, an effort that was significantly expanded thanks to a PEER Evidence to Action supplement awarded to Dr. Kagezi and his team in January 2018. Those funds supported a training needs assessment, development of a training curriculum, and delivery of training to more than 700 Ugandan farmers. The information gathered in the project was also used to update the coffee management calendars which have been used to train farmers and other stakeholders in Farmer Field Schools across the coffee-banana growing regions. In addition, the project contributed to building and improving the research capacity for Coffee Research Center through training of two Master’s-level students and provision of short-term courses to students, research technicians, and other COREC staff. The training curriculum developed under the supplement was selected for incorporation into the coffee training center at the National Coffee Research Institute (NaCORI), Kituza. It will also be used by other institutions involved in the promotion of coffee-related activities, such as the Uganda Coffee Development Authority (UCDA); Café Africa Uganda; the Directorate of Extension services of the Ministry of Agriculture, Animal Industry, and Fisheries (MAAIF); Hanns R. Neumann Stiftung (HRNS); and various Ugandan universities.

Although the PEER project and supplement funding have ended, Dr. Kagezi and his team continue to work on several ongoing research and training efforts building on their PEER research, including two major projects funded directly by USAID.
