34 pc of coastline under varying degrees of erosion for past 28 years: Govt
Jul 20, 2022
New Delhi [India], July 20 : Union minister Jitendra Singh on Wednesday said that about 34 per cent of the coastline in India is under varying degrees of erosion for the past 28 years.
In a written reply to a question in the Lok Sabha, Jitendra Singh informed that the National Centre for Coastal Research (NCCR), an attached office of the Ministry of Earth Sciences (MoES) is monitoring shoreline erosion since 1990, using remote sensing data and GIS mapping techniques.
He said, a total, of 6,907.18 km long coastline of the mainland has been analyzed for the period from 1990 to 2018 and it is observed that (33.6 per cent) of the coastline is under varying degrees of erosion for the past 28 years.
In a related question, the Union minister said, "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. INCOIS has carried out Coastal Vulnerability Index (CVI) mapping to assess the probable implications of sea-level rise along the Indian coast. This exercise has generated maps using seven input parameters: shoreline change rate, sea-level change rate, coastal elevation, coastal slope, coastal geomorphology, significant wave height and tidal range."
An atlas composing 156 maps of the entire Indian coast on a 1:1 lakh scale was released in 2012.
Moreover, the 15th Finance Commission recommended the creation of the National Disaster Risk Management Fund (NDRMF) and State Disaster Risk Management Fund (SDRMF) comprising the Mitigation Fund at the National and State level (NDMF/SDMF) and Response Fund at the National and State level (NDRF/ SDRF) for the award period from 2021-22 to 2022-26.
The Finance Commission has also made specific recommendations for "Mitigation Measures to Prevent Erosion" under NDMF and "Resettlement of Displaced People Affected by Erosion" under NDRF. To operate these funds, the Commission also suggested that NDMA and/ or Ministry of Home Affairs may develop suitable norms for mitigation measures to prevent erosion and both the Union and the state governments develop a policy to deal with the extensive displacement of people caused by coastal and river erosion.
At present, NDMA is in the process of preparing suitable norms for mitigation measures and developing a policy to deal with the extensive displacement of people.
