The Centre has observed that 33.6 per cent of the Indian coastline was vulnerable to erosion, 26.9 per cent was under accretion (growing), and 39.6 per cent was in a stable state.
One-third of India’s coastline is vulnerable to erosion, impacting coastal communities residing in erosion-prone areas, including fishermen communities.
The vulnerability of the Indian coastline has been estimated by the Indian National Centre for Ocean Information Services (INCOIS) on seven coastal parameters, i.e., shoreline change rate, sea-level change rate, coastal elevation, coastal slope, coastal geomorphology, significant wave height, and tidal range.
The National Centre for Coastal Research (NCCR) monitored India’s coastal areas for three decades between 1990-2018 through multi-spectral satellite images and ground surveys.
The Centre has observed that 33.6 per cent of the Indian coastline is vulnerable to erosion, 26.9 per cent was under accretion (growing), and 39.6 per cent is in a stable state.
This long-term shoreline analysis indicates that out of 550 km of the coast in Odisha, 28% of the coast is eroding, 21 per cent is stable, and 51 per cent is accreting…
