Question raised in Lok Sabha on coastal vulnerability index, 20/07/2022. Indian National Centre for Ocean Information Services (INCOIS) has not estimated the percentage of loss specifically due to coastal erosion, however, INCOIS has estimated Coastal Vulnerability Index (CVI) for the Indian coastline, which is a cumulative impact of seven coastal parameters. Further, the National Centre for Coastal Research (NCCR), an attached 0ffice of the Ministry of Earth Sciences (MoES) is monitoring shoreline erosion since 1990, using remote sensing data and GIS mapping techniques. Totally, 6907.18 km long coastline of the mainland as been analyzed for the period from 1990 to 2018. It is observed that (33.6%) of the coastline is under varying degrees of erosion for the past 28 years.
