The Environmentalist Foundation of India (E.F.I) is an environmental conservation group based out of Chennai, Hyderabad, Puducherry and Coimbatore which focuses on wildlife conservation and habitat restoration. Started in 2007 and registered in 2011, the organisation is known for its work in cleaning and scientific restoration of lakes in India for biodiversity.[1] The organisation and its efforts grew from that one pond in Chennai to include over 39 lakes and 48 ponds in Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, Pondicherry and Gujarat in the last 10 years (2007 to 2017) [2]


E.F.I focuses on restoration of lakes, flora, care of stray animals and a village development programme. Most of the organisation's work is carried out through volunteer support.[3] E.F.I organises lake clean ups every Sunday and as of 2014 had cleaned 39 lakes across India.

The lakes now have "G" shaped central islands for the birds to nest and fish to spawn. These geometric central islands are a first of its kind, with wind barrier capabilities and roosting facilities. The lakes also have percolation trenches and parallel bunds which ensure water retention and trapping of garbage.[5][7][8][9]
