The government of India established the Coastal Regulation Zone (CRZ) in 1991 with the goal of safeguarding coastal ecology and conserving the coastal environment

What is CRZ?

The region close to the coast known as the Coastal Regulation Zone (CRZ) consists of the shoreline up to 500 meters from the High Tide Line (HTL) plus a 100 meter stretch along the banks of streams, estuaries, backwaters, and rivers that are subject to tidal change.

These CRZ regulations apply to these zones.

In order to protect the fragile ecosystem next to the sea, the Coastal Regulation Zone (CRZ) regulations control and regulate commercial, human, and Industrial activities that are in close proximity to the shoreline. The Ministry of Environment, Forest and Climate Change (MoEFCC) released the Coastal Regulation Zone (CRZ) notification for the first time in 1991 in compliance with section 3 of the Environment Protection Act of 1986.
