Biodiversity conservation and ecological impact: a relevant GS3 and Environment case study.
Why in news
ATREE researchers warned that the National River-Linking Project could create 'ecological highways' for invasive species, threatening endemic biodiversity.
Background
The project proposes linking 37 river basins using 30 links to redistribute 174 billion cubic metres of water. It aims to generate 34,000 MW of power.
