Legal Basis for Ecologically Sensitive Areas

An Ecologically Sensitive Area (ESA) is a geographically identified area where specified activities may be prohibited, restricted or regulated to protect the environment. The Union government creates such a regulatory regime through an area-specific notification under the Environment (Protection) Act, 1986 and its rules; ESA is not a separate category requiring declaration under wildlife law.

Core statutory authority

The notification power flows principally from Section 3(1), which authorises the Central Government to take all measures it considers necessary to protect and improve environmental quality and to prevent, control and abate environmental pollution.

• Section 3(2)(v) specifically permits restriction of areas in which industries, operations or processes may not be carried out, or may be carried out only subject to prescribed safeguards.
• This area-based power allows the government to specify prohibited, regulated and permissible activities according to an area's ecological requirements.

Rule-based notification mechanism

Rule 5 of the Environment (Protection) Rules, 1986 operationalises the Act by permitting the Central Government to prohibit or restrict the location of industries and the carrying on of processes or operations in different areas.

• Under Rule 5(1), ecological considerations such as biological diversity, environmentally compatible land use and proximity to protected areas may inform restrictions.
• Rule 5(3) provides the notification procedure, including public notice of the proposed restrictions, reasons for them, invitation of objections and consideration of those objections before finalisation.

Legal character and effect

An ESA notification is delegated legislation issued by the Central Government, ordinarily through the Ministry of Environment, Forest and Climate Change. Its precise boundaries, activity classifications, safeguards and monitoring arrangements arise from the particular notification rather than from a uniform statutory template.

• The restrictions may differentiate between activities that are prohibited, regulated or permitted.
• Because each notification is area-specific, its text must be consulted to determine the applicable legal controls.
