Explanation:

• The National Wildlife Action Plan (2002-2016) of the Ministry of Environment, Forest and Climate Change (MoEFCC) stipulated that state governments should declare land falling within 10 km of the boundaries of national parks and wildlife sanctuaries as eco fragile zones or Eco Sensitive Zones (ESZs). 
• ESZs are prescribed under the Environmental (Protection) Act, 1986.
• The purpose of declaring ESZs around national parks, forests and sanctuaries is to create some kind of a “shock absorber” for the protected areas.
• These zones would act as a transition zone from areas of high protection to those involving lesser protection.

Hence only statement 1st is correct.
