Ecologically Sensitive Zones (ESZs)

What is Ecologically Sensitive Zones (ESZs)?

Ecologically Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) around Protected Areas (National Parks and Wildlife Sanctuaries) or other ecologically significant regions. Their primary purpose is to regulate and prohibit certain activities to minimize adverse impacts on the delicate ecosystem and provide a buffer.

Historical Background

The concept of ESZs gained prominence after the Wildlife (Protection) Act 1972 and the Forest (Conservation) Act 1980, to create buffer zones around protected areas. The Environment Protection Act (EPA) 1986, enacted in the wake of the Bhopal Gas Tragedy, provides the central government with broad powers to protect and improve the environment, including declaring ESZs.

Key Points

10 points
  • 1.

    Legal Basis: Declared under Section 3(2)(v) of the Environment Protection Act 1986 and Rule 5(1) of the Environment (Protection) Rules 1986.

  • 2.

    Purpose: To create a 'shock absorber' or transition zone around Protected Areas, reducing the impact of developmental activities and enhancing conservation.

  • 3.

    Extent: Typically extend up to 10 km around Protected Areas, though the extent can vary based on ecological sensitivity and local context.

  • 4.

    Prohibited Activities: Include commercial mining, setting up of polluting industries, major hydroelectric projects, establishment of sawmills, discharge of untreated effluents, and commercial use of firewood.

  • 5.

    Regulated Activities: Include felling of trees, establishment of hotels/resorts, natural gas production, non-polluting industries, construction activities, and tourism, requiring prior permission and environmental clearance.

  • 6.

    Permitted Activities: Organic farming, use of renewable energy sources, rain-water harvesting, adoption of green technology, and existing agricultural practices.

  • 7.

    Zonal Master Plan: Each ESZ requires a Zonal Master Plan to be prepared by the State Government, integrating conservation and development, and approved by the MoEFCC.

  • 8.

    Monitoring Committee: A Monitoring Committee is constituted at the district level to oversee the implementation of the Zonal Master Plan and monitor compliance.

  • 9.

    Role of EPA 1986: Provides comprehensive powers to the Central Government to take measures for environmental protection, including setting standards, restricting industrial operations, and inspecting sites.

  • 10.

    Identification Criteria: Based on factors like species endemism, rarity, ecological fragility, geomorphological features, and biological richness.

Recent Developments

5 developments

Ongoing debate on the extent of ESZs, particularly concerning human settlements and development needs.

Supreme Court directives on mandatory ESZs around Protected Areas, leading to increased notifications.

Challenges in implementing Zonal Master Plans and ensuring effective monitoring by state governments.

Increased focus on identifying and protecting other ecologically sensitive areas beyond Protected Areas, such as parts of the Western Ghats and Aravallis.

The current news highlights the judiciary's role in enforcing protection in such sensitive areas, even if not formally notified as ESZs under the 10 km rule.
