GS Paper 3
Topics Covered: Conservation, environmental pollution and degradation, environmental impact assessment.
Context:
Ministry of Environment, Forest and Climate Change has notified the eco-sensitive zone of the Deepar Beel Wildlife Sanctuary on the south-western edge of Guwahati.
- The notification specified an area “to an extent varying from 294 metres to 16.32 km” as the eco-sensitive zone, with the total area being 148.9767 sq. km.
Need for:
The wetland has for decades been threatened by a railway track — set to be doubled and electrified — on its southern rim, a garbage dump, and encroachment from human habitation and commercial units.
Implications of the latest move:
- No new commercial hotels and resorts shall be permitted within 1 km of the boundary of the protected area or up to the extent of the eco-sensitive zone, whichever is nearer, except for small temporary structures for eco-tourism activities.
- Among activities prohibited in the eco-sensitive zone are hydroelectric projects, brick kilns, commercial use of firewood and discharge of untreated effluents in natural water bodies or land areas.
About Deepar Beel:
Deepar Beel is one of the largest freshwater lakes in Assam and the State’s only Ramsar site besides being an Important Bird Area.
- It is a permanent freshwater lake, in a former channel of the Brahmaputra River, to the south of the main river.
Why this wetland needs protection?
The wetland of Deepar Beel constitutes a unique habitat for aquatic flora and avian fauna.
- About 150 species of birds have been recorded in the sanctuary, out of which two are critically endangered, one endangered, five vulnerable and four near-threatened.
- Elephants regularly visit the wetland from adjoining Rani and Garhbhanda Reserve Forest and the wetland is an integral part of the elephant habitat.
- Besides these, 12 species of reptiles, 50 species of fish, six species of amphibians along with 155 species of aquatic macro-biota have been recorded in the sanctuary.
What are the Eco-sensitive Zones (ESZs)?
- Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
- The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
- They also act as a transition zone from areas of high protection to areas involving lesser protection.
- The Environment (Protection) Act, 1986 does not mention the word “Eco-Sensitive Zones”.
- An ESZ could go up to 10 kilometres around a protected area as provided in the Wildlife Conservation Strategy, 2002.
- Moreover, in the case where sensitive corridors, connectivity and ecologically important patches, crucial for landscape linkage, are beyond 10 km width, these should be included in the ESZs.
