Ministry of Environment Notifies Eco-Sensitive Zones Around Nine Western Ghats Sanctuaries

The Ministry of Environment, Forest and Climate Change (MoEFCC) has issued final statutory notifications establishing Eco-Sensitive Zones (ESZs) around nine wildlife sanctuaries and national parks across the Western Ghats biodiversity hotspot. Published on July 25, 2026, the notification delineates buffer zones ranging from 1 km to 4 km around protected boundaries in Kerala, Karnataka, and Tamil Nadu. The regulation prohibits commercial mining, stone quarrying, polluting industries, and large hydroelectric projects while safeguarding traditional indigenous agriculture and local community livelihoods.

Context & Background

The Western Ghats is a UNESCO World Heritage site and one of the world's eight 'hottest hotspots' of biological diversity, harboring thousands of endemic plant and animal species. However, unchecked granite quarrying, deforestation, and construction activities have increased landlessness and severe landslide vulnerabilities during monsoon months. Following recommendations of expert panels including the High-Level Working Group chaired by Dr. K. Kasturirangan and Supreme Court directives on mandatory 1 km buffer zones around protected forests, the MoEFCC conducted extensive ground-truthing and consultations with state forest departments. The finalized notifications categorize activities into prohibited, regulated, and promoted groups.

Regulated activities—such as eco-tourism, small-scale rainwater harvesting, and organic farming—require approval from local Zonal Master Plans supervised by District Collectors.

The notification mandates setting up multi-stakeholder monitoring committees involving local Gram Sabha representatives, biodiversity experts, environmental law specialists, and senior state forest officials to resolve land use disputes promptly and prevent ecological degradation across mountain slopes and watershed zones.

Significance & Environmental Protection Impact

Notifying Eco-Sensitive Zones around Western Ghats sanctuaries establishes vital ecological corridors for endangered wildlife like the Asian elephant, Bengal tiger, and Nilgiri Tahr. Prohibiting heavy mining and commercial blasting preserves fragile slope hydrology, reducing catastrophic landslide risks in mountain districts. Legally, statutory ESZ boundaries provide forest officials with enforcement mechanisms under the Environment (Protection) Act, 1986, to stop illegal commercial encroachments. For local hill communities, the rules preserve traditional agriculture while promoting sustainable eco-tourism and organic farm produce branding.

Conservation biologists highlight that protected buffer zones reduce human-wildlife conflict along agricultural borders.

Exam Relevance & Syllabus Connection

This environmental notification is relevant for the UPSC CSE under GS Paper 3 (Conservation, environmental pollution and degradation; Biodiversity hotspots; Environment Protection Act 1986). Candidates should study Western Ghats ecology, Kasturirangan and Gadgil committee reports, ESZ notification guidelines, and Supreme Court environmental rulings.
