Western Ghats Ecologically Sensitive Area
Why in the news
- The Union Environment Ministry issued a fresh draft notification on 27 July 2026 proposing an Ecologically Sensitive Area across parts of the Western Ghats.
- Residents of several Kerala villages objected to their inclusion, arguing that inaccurate mapping could affect housing, agriculture and local infrastructure.
- The Ministry invited public comments on the draft until 25 September 2026. MoEFCC notification update
Importance of the Western Ghats
- The Western Ghats extend for approximately 1,600 kilometres through Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu.
- They are one of the world’s major biodiversity hotspots, with high levels of endemism.
- They influence the Indian monsoon and contain the headwaters of several peninsular rivers, including the Godavari, Krishna, Kaveri and Periyar.
- Parts of the Western Ghats are recognised as a UNESCO World Heritage Site.
Western Ghats Ecology Expert Panel
The Western Ghats Ecology Expert Panel was constituted in 2010 under ecologist Madhav Gadgil.
It is commonly called the Gadgil Committee.
It treated the Western Ghats as a connected ecological system rather than a collection of isolated protected areas.
It recommended declaring the entire Western Ghats landscape an Ecologically Sensitive Area.
It proposed three regulatory categories:
- ESZ-1: Areas of the highest ecological sensitivity, requiring the strongest restrictions.
- ESZ-2: Areas where limited development could continue under environmental safeguards.
- ESZ-3: Relatively less sensitive areas where development could be permitted with regulation.
It recommended:
- Prohibition of mining in the most sensitive areas.
- Phasing out highly polluting industries.
- Restrictions on large dams and environmentally destructive construction.
- Greater decision-making power for gram sabhas and local governments.
- Creation of a statutory Western Ghats Ecology Authority under the Environment (Protection) Act.
State governments criticised the recommendations as too extensive and difficult to implement in a densely inhabited landscape.
Kasturirangan Committee
The High-Level Working Group chaired by K. Kasturirangan was constituted after objections to the Gadgil report.
It distinguished between:
- Natural landscape: Forests, wildlife habitats and relatively undisturbed ecosystems.
- Cultural landscape: Settlements, plantations and agricultural land substantially modified by human activity.
It recommended bringing approximately 37% of the Western Ghats—about 59,940 square kilometres—under the proposed ESA.
It excluded most settlements, plantations and agricultural areas from the recommended ESA.
It proposed prohibiting mining, quarrying, sand mining, thermal power plants and highly polluting industries in the ESA.
Its narrower, satellite-based approach became the basis for subsequent Union government draft notifications. Kasturirangan committee report
Oommen V. Oommen Committee
- Kerala appointed a State-level expert committee chaired by Oommen V. Oommen to examine the Kasturirangan recommendations.
- It conducted field-level consultations in affected areas.
- It recommended excluding inhabited areas, farms and plantations from the ESA.
- It favoured cadastral and ground-level mapping instead of relying only on satellite images.
- Its recommendations reflected Kerala’s distinctive settlement pattern, where villages, farms, plantations and forest areas frequently overlap.
Core policy issue
- An ESA is not the same as a national park or wildlife sanctuary.
- It principally regulates environmentally harmful activities rather than evicting existing residents.
- Incorrect mapping can nevertheless produce uncertainty over construction, land use and local development.
- Final demarcation should therefore combine scientific conservation criteria with cadastral maps, physical verification and gram-sabha consultation.
The draft Western Ghats ESA notification revived the challenge of protecting a biodiversity hotspot while accurately mapping densely inhabited landscapes.
