- (a)      A  Memorandum  of  Understanding  (MoU)  was  signed  on  12 th  May  2010 between the Ministry of Environment, Forests and Climate Change (MoEF & CC) and the Survey of India (Department of Science & Technology) to carry out large scale mapping for finalizing the hazard line along India's Coast. This project was aimed for Integrated  Coastal  Zone  Management (ICZM) by the  MoEF & CC. The final deliverables i.e. large scale mapping data for ≈ 75,000 Sq Km area covering ≈ 7 km strip width along the coast has been handed over to MoEF & CC. Hazard Line Coastal
- delineation was carried out by National Centre for Sustainable Management (NCSCM), MoEF & CC, Govt. of India, New Delhi.
- (b)      The final deliverables for West Coast and East Coast were handed over to Society of Integrated Coastal Management (SICOM), MoEF & CC, New Delhi in the Year  2018. In  the  complete  process  1:10,000  scale  maps  with  0.5  m  contour interval,  DEM  and  ortho  photos,  Shore  Line,  High  Tide  Line,  Flood  Line,  Erosion Line and Composite Hazard Line were provided.

(c)     The Ministry of Environment, Forest & Climate Change (MoEF&CC), Govt. of India  issued  amendment  to  the  CRZ  Notification,  2011,  dated  2/07/2018  which states that the 'Hazard line shall be used as a tool for disaster management plan for  the  coastal  environment,  including  planning  of  adaptive  and  mitigation measures  and  that  with  a  view  to  reduce  the  vulnerability  of  the  coastal communities  and  ensuring  sustainable  livelihood,  the  land  use  planning  for  the area between the Hazard line and HTL shall take into account such impacts of climate change and shoreline changes, while drawing the Coastal Zone Management Plans (CZMPs)'.

The same provision has been incorporated in the Coastal Regulation Zone (CRZ) Notification, 2019. Accordingly, the Hazard line is being used as a tool for disaster  management  plan  for  the  coastal  environment,  including  planning  of adaptive and mitigation measures.

- (d)     Yes, Sir.
- (e)     Para 10.2 of the CRZ Notification, 2019 contains provisions for CRZ for the inland backwater islands and islands along mainland coast, as given below:-
- (I)   All  the  inland  islands  in  the  coastal  backwaters  and  islands  along  the mainland coast shall also be covered under this notification.
- (II)  In view of the unique coastal systems of backwater islands and islands along the mainland coast, along with space limitations in such coastal stretches, CRZ of 20 meters from the High Tide Line (HTL) on the landward side shall uniformly apply to such islands and activities shall be regulated as under: -
- (i)  Existing  dwelling  units  of  local  communities  may  be  repaired  or reconstructed within 20 meters from the HTL of these islands; however, no new construction shall be permitted in this zone;
- (ii) foreshore facilities, such as fishing jetty, fish drying yards, net mending yard,  fishing  processing  by  traditional  methods,  boat  building  yards,  ice  plant, boat  repairs  and  the  like,  may  be  taken  up  in  CRZ  limits  subject  to  due environmental safeguards.

(III)  Integrated Island Management Plans (IIMPs), as applicable to smaller islands in  Lakshwadweep  and  Andaman  &  Nicobar,  as  per  Island  Protection  Zone Notification, 2011 number S.O. 20(E), dated the 6th January, 2011, are formulated by  respective  State  or  Union  Territory  for  all  such  islands  and  submitted  to Ministry of Environment, Forest and Climate Change and till the IIMPs are framed, provisions of this notification shall not apply and the Coastal Zone Management Plans (CZMP) as per provisions of CRZ Notification 2011 number S.O. 19(E), dated the 6th  January, 2011, shall continue to apply.
