## STUDIES FOR COASTAL EROSION

2004. Shri Dhaval Laxmanbhai Patel:

Will the Minister of EARTH SCIENCES be pleased to state:

- (a) the details of key findings of the latest shoreline change and coastal erosion studies conducted by the National Centre for Coastal Research (NCCR) along with the Valsad and Navsari coast during the last five years;
- (b) the names of villages in Valsad district identified by NCCR as erosion-prone or highrisk zones;
- (c) whether the  NCCR has carried out any site-specific  coastal  erosion  assessment  for Tithal  beach  and  surrounding  areas  and  if  so,  the  details  of  the  coastal  protection measures recommended; and
- (d) whether any technical or financial assistance has been provided by Government for coastal protection or erosion-mitigation works in Valsad and Navsari districts and if so, the details thereof?

## ANSWER

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

- (a) National Centre for Coastal Research (NCCR) an attached office under Ministry of Earth Sciences, has carried out an updated assessment of shoreline changes along the coastal districts of Valsad and Navsari of Gujarat coast using remote-sensing datasets for the period 1990-2022. The results indicate that about 58% (36.62 km) of the Valsad coastline experienced erosion of varying intensity, including 2.5 km under high erosion, 3.24  km  under  moderate  erosion,  and  the  remaining  30.88  km  under  low  erosion. Similarly, around 60% (24.64 km) of the Navsari coastline was found to be undergoing erosion, comprising 3.86 km under high erosion, 4.60 km under moderate erosion, and 16.18 km under low erosion categories.
- (b) As per NCCR shoreline change classification, the region north of Udvada is identified as  a  high-erosion  zone,  while  the  Bhagal  coastal  stretch  falls  under  the  moderateerosion  category;  both  are  considered  erosion-prone/high-risk  areas.  Other  coastal stretches such as Govada, Dehri Beach, Umbergaon Beach, Nargol, Malwan Beach, Maroli, Kalgam Bariyawad Beach, Fansa, Umarsadi, Tithal and Kosamba are classified under the low-erosion category.
- (c) Yes Sir. NCCR has carried out a long-term (32-year) shoreline change assessment for entire coastline including Tithal region. However, NCCR has not recommended any coastal protection.
- (d) NCCR  undertakes  systematic R&D  work  on  coastal processes and shoreline management,  and  assists  coastal  States/UTs  by  identifying  vulnerable  stretches, recommending  site-specific  mitigation  measures,  and  supporting  the  preparation  of Shoreline Management Plans (SMPs). Implementation of these measures' rests with the  respective  coastal  States/UTs.  However,  to  address  erosion-related  issues,  the Government has issued Guidelines for Appraisal and Release of Funds for Coastal and River Erosion under the National Disaster Management Fund (NDMF) on 20th June 2024,  based  on  the  15th  Finance  Commission's  recommendations.  The  guidelines provide for both erosion mitigation measures  under the NDMF and resettlement of displaced  populations  under  the  National  Disaster  Relief  Fund  (NDRF)  with  a recommended allocation of Rs. 1500 crore for 2021-26.
