Nepal is draining four glacial lakes. Scientists say it is not enough
Summary
Nepal is spending about $50 million to lower the water levels of four high-risk glacial lakes, but scientists say the plan is too limited to protect downstream settlements. Experts argue the lakes need case-by-case studies, deeper lowering where necessary, and stronger early warning and risk-reduction measures.
Key Points
- Nepal is moving ahead with a $50 million project to lower four glacial lakes in the Koshi and Gandaki basins after the deadly Bhotekoshi floods.
- Scientists say the planned three-to-four-metre lowering is not enough and should be based on lake-specific hydrology and risk studies.
- Experts warn that lake lowering alone will not make communities safe without early warning systems, better hazard assessments and reduced exposure downstream.
- Researchers say Nepal’s glacial-lake risk assessments are outdated and must be updated to reflect new events and broader glacier hazards.
