Rwanda Plans $1.1 Million for Lake Weed Removal

The Rwanda Water Resources Board (RWB) announced a plan to spend roughly 1.5 billion Rwandan francs—about $1.1 million USD—to remove water hyacinth from seven lakes in the Eastern Province. The invasive aquatic weed, known locally as amarebe, blocks sunlight and reduces oxygen, harming aquatic life and impacting transportation. This initiative aligns with the inaugural Lake Victoria Basin Day on May 21, a regional effort to conserve lake resources.

The RWB intends to purchase specialized equipment for removing the weed from lakes Cyohoha South, Rweru, Mugesera, Ihema, Birira, Mihindi, and Sake. Most of Rwanda’s lakes drain into the Akagera River, a tributary of Lake Victoria, making their health crucial to the wider basin. Initial funding of 153 million Rwandan francs has been allocated for the 2026/27 budget, with officials seeking additional funds.

Beyond removal, communities are finding uses for water hyacinth, crafting it into products like baskets and furniture. However, the plant still threatens power generation—currently reducing output at the Rusumo Hydroelectric Power Plant by about five megawatts daily—and requires ongoing management.
