20.3.1. Impacts on Coastal States in India


The coastal states of Maharashtra, Goa and Gujarat face a grave risk from the sea level rise, which could flood land (including agricultural land) and cause damage to coastal infrastructure and other property.

Goa will be the worst hit, losing a large percentage of its total land area, including many of its famous beaches and tourist infrastructure.

Mumbai’s northern suburbs like Versova beach and other populated areas along tidal mud flats and creeks are also vulnerable to land loss and increased flooding due to sea level rise.

Flooding will displace a large number of people from the coasts putting a greater pressure on the civic amenities and rapid urbanisation.

Sea water percolation due to inundations can diminish freshwater supplies making water scarcer.


The states along the coasts like Orissa will experience worse cyclones. Many species living along the coastline are also threatened.

The coral reefs that India has in its biosphere reserves are also saline sensitive and thus the rising sea level threatens their existence too, not only the coral reefs but the phytoplankton, the fish stocks and the human lives that are dependent on it are also in grave danger.

People living in the Ganges Delta share the flood risks associated with rising sea levels.
