Why this matters now

CRZ is tested for its legal basis, the zone categories and the 2019 changes — central to coastal ecology, fisher livelihoods, tourism and the blue economy.

What is the CRZ?

Issued under the Environment (Protection) Act, 1986, the CRZ Notification regulates the coastal stretch within 500 m of the High Tide Line (and along tidal water bodies) to protect coastal ecosystems and communities. It is enforced through Coastal Zone Management Authorities (NCZMA/SCZMAs) and state Coastal Zone Management Plans.

The CRZ categories

  • CRZ-I — ecologically sensitive areas (mangroves, corals, turtle-nesting); most protected;
  • CRZ-II — already developed urban areas;
  • CRZ-III — relatively undisturbed rural areas;
  • CRZ-IV — the water area (intertidal/territorial waters).

The 2019 changes and coastal management

The CRZ Notification 2019 relaxed norms — easing the no-development zone for densely populated areas, promoting tourism infrastructure and streamlining clearances — to spur coastal development and the blue economy. This is balanced through Integrated Coastal Zone Management (ICZM) and concerns over diluting ecological safeguards.

UPSC angle

Know CRZ under the EP Act 1986 (500 m HTL), the four categories (I sensitive → IV water), the CZMAs, and the CRZ 2019 relaxations and ICZM/blue-economy link.
