- PhD Title: Ecological Sustainability of Cage Aquaculture in African Lakes: Limnological Analysis, Water Quality, and Greenhouse Gas Dynamics in Lakes Kivu and Muhazi, Rwanda
- Year of Completion: 2026

PhD Overview
Cage aquaculture is expanding rapidly across African inland lakes, raising concerns about its ecological sustainability. Fully by the Schlumberger Foundation’s Faculty for the Future program, my PhD research examines the environmental effects of cage farming in Lakes Kivu and Muhazi, with a focus on water column stratification, mixing dynamics, water quality assessments and greenhouse gas (GHG) flux measurements in cage aquaculture bays. The study examines nutrient cycling, oxygen distribution, and methane emissions to determine how cage aquaculture affects biogeochemical conditions. The findings inform sustainable cage aquaculture development and ecosystem-based management strategies for tropical lakes facing increasing cage aquaculture pressure.
Sustainability Goals
- Climate Action
- Life Below Water
- Responsible Consumption and Production
