Evidence for Nature-based Solutions: How Five Countries Built a Regionally Owned Environmental Database for Lake Victoria
Lake Victoria, shared by five East African countries, supports over 45 million people through fisheries, water supply, and agriculture. Declining water quality, rising pollution, and the absence of a shared evidence base made coordinated basin management difficult. To address this, the Lake Victoria Basin Commission (LVBC), with GIZ support under the EAC4Nature project, developed the first-ever State of the Basin Report (SoBR).
The approach combines joint water quality sampling at 44 stations across three countries, consultations with all five Partner States – Burundi, Kenya, Rwanda, Tanzania, and Uganda, and integration of findings into the Lake Victoria Basin Water Information System (LVB-WIS).
The SoBR follows a five-year cycle as a shared baseline for planning, policy, and investment. It identifies Nature-based Solutions – wetland rehabilitation, reforestation, and catchment restoration – as the most cost-effective pathway to improve water quality and build climate resilience. All five Partner States endorsed the report.
