NCCR On Coast Erosion Care

New Delhi: Union Minister Earth Sciences, Jitendra Singh said that a total of 6,632 Kilometer  long Coastline of the country including Odisha is under varying degree of erosion.

This has been analysed from 1990 to 2018 and it is noted that about 33.6 Per cent of the coastline is under varying degree of erosion.

In a written reply to a question in the Rajya Sabha today, Dr. Singh said, National Centre for Coastal Research (NCCR), an attached office of Ministry Of Earth Science (MoES) is monitoring the shoreline erosion since 1990 using remote sensing data and GIS mapping techniques.

Accordingly technical support is being extended by NCCR to Odisha for implementing shore line protection.

In Odisha areas of  Ramayapatna in Ganjam, Puri, Konark and Pentha are having vulnerable stretches, for which technical support are extended by NCCR.

Dr. Singh said, the reasons for coastal erosions include increase in frequency of Cyclones and Sea level rise and anthropogenic activities such as construction of harbours, beach mining and building of dams.

He said, there are 526 maps prepared for entire Indian coast for identifying areas vulnerable to coastal erosion in 1:25000 scale along with 66 district maps, 10 State and Union Territories maps.

A Report on “National Assessment of Shoreline Changes along Indian Coast” is released in July, 2018 and shared with various Central and State government Agencies and Stakeholders for implementing shore line protection measures. The digital and hard copy of all the Maps is released on 25th March, 2022.

Dr Jitendra Singh said, the Ministry of Earth Sciences (MoES) had successfully demonstrated innovative coastal erosion mitigation measures at two pilot locations at  Puducherry Beach Restoration Project and Kadalur  Periya  Kuppam, Tamil Nadu.

The Submerged Reef has been implemented by MoES and beach nourishment is implemented by Government of Puducherry. This helped in restoration of 1.5 km long city beach after 30 years and helped in improving tourism and fishing activities in addition to protection of coast during extreme cyclonic events.

An Offshore submerged dyke was implemented. This helped in protection of three fishing Villages during extreme cyclonic events and restored lost beach that is being used for landing of fishing boats and other fishing activities.

In addition, NCCR is also providing technical support to state governments of Kerala (Chellanam, Kollamkode, Poonthura, Varkala and Shangumugham) Andhra Pradesh (Vishakapatnam) and Goa for implementation of coastal protection measures at vulnerable stretches.
