Nearly 50,000 large dams worldwide could lose more than a quarter of their storage capacity by 2050 as a result of sedimentation build-ups, eroding global water and energy security, according to United Nations research on Wednesday.

Dam capacity is expected to drop from 6 trillion cubic metres to 4.655 trillion cu m by 2050, and action must be taken to address the problem and protect vital storage infrastructure, the United Nations University said.

Impeding sediment flows along a river can also make upstream regions more prone to flooding and erode downstream habitats. Critics have long warned that the long-term social and environmental costs of giant dams far outweigh their benefits.
