## ANSWER

## THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR MINISTRY OF SCIENCE AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

- Indian National Centre for Ocean Information Services (INCOIS) has not estim ted the percentage of loss specifically due to coastal erosion, however, INCOIS has estimated CoiastalVulnerability Index (CVI) for the Indian coastline, which is a cumulative impact of Jeven ~oastal parameters. Further, the National Centre for Coastal Research (NCCR), an attached 10ffice,lof the Ministry of Earth Sciences (MoES) is monitoring shoreline erosion since 1990, usin~ remo e 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 c l l astlin is under varying degrees of erosion for the past 28 years. (a)
- Yes sir. (b)
- INCOIS has carried out Coastal Vulnerability Index (CVI) mapping to a sess the probable ~mplicationsof sea-level ~ise along the Indian coast. This exercise has geJerate 1 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 1 com j PbSing 156 maps of the entire Indian coast on a 1:1 lakh scale was released in 2012. (c)
- Yes, Sir. 15 th Finance Commission recommended the creation of atio al Disaster Risk Management Fund (NDRMF) and State Disaster Risk Management Fu I d (S RMF) comprising Mitigation Fund at the National and State level (NDMF/SDMF) anq Res fnse Fund at the National and State level (NDRFI SDRF) for the award period from 2021-22 to 2t22-26. (d)
- The Finance Commission has also made specific recommendations for r'Mit;' ation Measures to Prevent Erosion" under NDMF and "Resettlement of Displaced Peop e Am cted by Erosion" under NDRF. To operate these funds, the Commission also suggested that ND and! or Ministry of Home Affairs may develop suitable norms for mitigation measures to :~reve~terosion and both the Union and the State Governments develop a policy to deal with the eftensiye displacement of people caused by coastal and river erosion. At present, NDMA is in the Ifroce~s of preparing the suitable norms for mitigation measures and developing a policy to eal with the extensive displacement of people' (e)
