A latest study by the Centre for Ecological Sciences (CES), Indian Institute of Science (IISc), has shown that 54 per cent of lakes in the City have been encroached upon for construction activities and turned into garbage dump yards.

One of the prime lakes in the City, Sankey Tank, too faces the threat of increasing pollution and encroachment. The government claims that Sankey Tank is a model lake but in reality, it is highly polluted, shows a report published by Centre for Environmental Studies, Indian Institute of Science.

This set of Recommendations has emanated from a two-day National Workshop on Critical Tiger Habitats and Critical Wildlife Habitats held at the Indian Institute of Science (IISc) on 8th and 9th May 2008.
