Ambikapuram valley is an area of over 200 acres in Hubbathalai Panchayat, Coonoor Taluk in the Nilgiris district of Tamil Nadu. This valley is a typical example of many such across the district. There are springs in the upper reaches, streams and wetlands in the valley that are major sources of water supply. Changes in land use have a major impact on the quantity and quality of water in the valley. The time slider below enables us to compare imagery from 2012 and 2018 to assess changes over time.
