The tranquil stretches of emerald green backwaters in Mumbai and Kerala are among several locales in the western and eastern coasts facing threat from the rising sea level due to climate change.

According to a Government report, deltas of the Ganga, Krishna, Godavari, Cauvery and Mahanadi on the east coast may also be threatened along with irrigated land and adjoining settlements.

The report submitted to the UN, was prepared by multi-disciplinary teams and other stakeholders comprising more than 220 scientists belonging to over 120 institutions.

The experts who prepared the report visited some vulnerable areas, including the 2004 tsunami-hit Nagapattinam in Tamil Nadu, backwaters surrounding Kochi in Kerala and Paradip in Odisha, in order to make a detailed impact study of the rise in sea level.
