Forests & Drinking Water

Lands with the greatest potential impact on drinking water based on the erosion risk of the land, downstream population, and state of the forests.

Forests & Hydropower

Upstream erosion, often caused by deforestation or poor land conservation practices, can reduce the lifespan and profitability of hydropower plants.

These indicators show how each major hydropower plant may be affected by upstream forests.

1. Upstream deforestation index

Portion of upstream watershed which has been deforested since 2012, weighted by erosion risk.

High Low

2. Restoration potential index

Portion of upstream watershed which has the opportunity to be restored, weighted by erosion risk.
