## ANSWER MINISTER FOR MINISTRY OF EARTH SCIENCES MINISTRY OF EARTH SCIENCES (DR. HARSH VARDHAN)

- (a) Yes, Madam.
- (b) National Centre for Coastal Research (NCCR) an attached office of MoES is  monitoring  the  Shoreline  Changes  along  Indian  Coast.    The  shoreline mapping  of  the  entire  main  land  of  India  has  been  completed  and shoreline is mapped in 1:25,000 scale.  Under this programme, about 6632 km long coastline distributed among nine coastal States and two Union Territories  was  analyzed  using  26  years  of  satellite  data  for  the  period 1990-2016  and  field  verifications  to  estimate  the  shoreline  change  i.e. erosion, accretion and stable.  From the analysis, it is found that 33%  of coast was eroding, 29% was accreting and 38% was in stable state.  The details for Odisha coast are summarized below
- (c) About  550  kms  along  shoreline  of  Odisha  coast  spreading  across  six coastal districts is also mapped.  The result of shoreline changes analysis for the period of 1990-2016 indicates that 28% of Odisha coast comes in erosion  category,  21%  stable  and  51%  of  accreting  nature.    Erosion  is mainly noticed in Jagatsinghpur and Kendrapara districts.  Pocket erosion was  also  noticed  at  north  of  Gopalpur  port,  Devi  River,  Wheeler  Island, Rushikulya River Island, Pentha, Gahirmatha, Satbhaya etc.
- (d) Yes,  the  Ministry  of  Water  Resources  in  collaboration  with  the  Space Application Centre (SAC) Ahmedabad has prepared an Atlas on shoreline changes  which  provides  the  extent  of  coastal  sea  erosion.  Further,  the Ministry  of  Environment  and  Forest  and  Climate  Change  (MoEF&CC) provides  advice  for  mitigation  options,  monitoring  measures  to  prevent and reduce significant adverse environmental and social impacts on the coast for sustainable development.
- (e) The  NCCR  has  developed  a  web  based  application  to  provide  the information on shoreline changes for the entire country including Odisha. Similarly,  MoEF&CC  through  its  National  Centre  for  Sustainable  Coastal Management (NCSCM), provides input and advice on all the components of Coastal environment impact assessment.
