For Prelims

Ecologically Sensitive Zone (ESZ):

  • ESZs also known as Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
  • They are created to be the “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
  • The Environment (Protection) Act, 1986 does not contain the word “Eco-Sensitive Zones”.
  • Supreme Court declared a mandatory minimum of 1km of ESZ to serve as a buffer for every national park and wildlife sanctuary in the country.
  • In case any national park or protected forest already has a buffer zone extending beyond one km, that would be maintained.
  • Eco-sensitive zones need not be uniform all around and it could have variable width and extent.

Rules for ESZ:

  • The National Wildlife Action Plan (2002-2016) of MoEFCC encourages the state governments to declare land falling within 10 km of the boundaries of national parks and wildlife sanctuaries as eco-fragile zones or Eco-Sensitive Zones (ESZs) under the Environmental (Protection) Act, 1986.
  • The Supreme Court, on June 3, 2022, directed that every national park and wildlife sanctuary in the country will have a mandatory eco-sensitive zone (ESZ) of at least one kilometre starting from its demarcated boundaries.
