Island Coastal Regulation Zone (ICRZ) Plan and Integrated Island Management (IIM) Plan for the Islands

The Ministry of Environment and Forests under the Environment (Protection) Act, 1986 has notified the Island Protection Zone (IPZ) Notification, 2011 alongside the Coastal Regulation Zone (CRZ), 2011 with the objective of

  • Ensuring livelihood security to the fishing communities, tribals and other local communities living in the coastal areas.
  • Conserving and protecting coastal stretches.
  • Promoting development in a sustainable manner based on scientific principles, taking into account the dangers of natural hazards in the coastal areas and sea level rise due to global warming.

Andaman & Nicobar (A&N) Islands comprises 572 Islands, Islets and rocky outcrops. There are 37 inhabited islands. Out of which, 10 islands in the South Andaman District, 14 in the North & Middle Andaman District and 13 in the Nicobar District. Total geographical area of A & N Islands is 8,249 sq. Km with a coastline of 1,962 km. The Lakshadweep archipelago consists of 36 islands with an area of 32 sq km. There are 12 atolls, three reefs, five submerged banks and ten inhabited islands in the Lakshadweep.

These two groups of oceanic islands are home to some of the country's most thriving biodiversity hotspots. While the islands of Middle Andaman, North Andaman, South Andaman, Greater Nicobar, Baratang, Havelock, Little Andaman, Car Nicobar, Neil and Long islands in Andaman and Nicobar Islands are to be managed as per the Island Coastal Regulation Zone (ICRZ) Plan, the rest of the islands in Andaman and Nicobar and all the islands in Lakshadweep are to be managed in accordance with the Integrated Island Management (IIM) Plan, as provided under the IPZ Notification, 2011.

While preparing an ICRZ plan, the hazard line, which is demarcated based on tides, waves, sea level rise and shoreline changes, would be taken into account. The ICRZ would address vulnerability to human life and properties, based on elevation, geomorphology, sea level trends and horizontal line displacement and indicate suitable areas that are safe for locating dwelling units and other infrastructure. All developmental activities would be regulated within the framework of ICRZ Plan.

The IIM plan would indicate all the existing and the proposed developments, conservation and preservation schemes and dwelling units including infrastructure projects such as, schools, markets, hospitals, public facilities and the like, which would be collected from the respective union territory (UT) administration. Ecologically sensitive areas and the developmental activities in the islands including requirements of the Ministry of Defence would also be taken into consideration while preparing the Integrated Islands Management (IIM) Plan, as specified in the IPZ Notification, 2011. Appropriate safeguard measures to protect the life and property of the local communities and infrastructure from natural hazards would be indicated in the IIM Plan. All developmental activities, listed under the Island Protection Zone Notification, 2011, would be regulated within the framework of IIM Plan of Andaman and Nicobar and Lakshadweep.

NCSCM would develop the process guidelines and extend technical assistance to the UT Administration in preparing the Island Coastal Regulation Zone (ICRZ) Plan and Integrated Island Management (IIM) Plan while the respective UT administration would prepare the ICRZ / IIM Plans for regulating developmental activities in their coastal environment including for ICZM plan preparation for a selected area or Island as desired by UT Administration.
