Deepor Beel Wildlife Sanctuary notified as eco-sensitive zone


  • Recently, the Ministry of Environment, Forest and Climate Change notified the eco-sensitive zone of the Deepor Beel Wildlife Sanctuary on the south-western edge of Guwahati.

Key Details

  • 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.
  • But being adjacent to “fast-developing Guwahati”, the Deepor Beel Wildlife Sanctuary is “facing immense biotic pressure by way of human settlements and ever-increasing development activities”
  • The Deepor Beel wetland expands up to 30 sq. km in summer and reduces to about 10 sq. km in the winter. The wildlife sanctuary measures 4.1 sq. km within this wetland.
  • The zonation should help, but Deepar Beel’s water has become toxic and it has lost many of its aquatic plants that elephants would feed on. The wetland can breathe easier only if the railway track is diverted.
  • 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.
  • City wastes as well as industrial effluents causing serious problem to the ecological and environmental values of the rich wetland that create a threat to all life forms and ecosystems in the Deepar Beel.

Eco-Sensitive Zone

  • It is the area that has been notified by the Ministry of Environment, Forests and Climate Change (MoEFCC), as areas around the Wildlife Sanctuaries, National Parks and Protected Areas as requiring more protection due to their fragility.
  • Objectives:
    • To manage and regulate the activities around these areas with the intention of creating some kinds of ‘shock absorbers’
    • To provide a transition zone between the highly protected and relatively less protected areas.
    • To give effect to Section 3(2)(v) of the Environment Protection Act, 1986 which restricts the operation of industries or processes to be carried out in certain areas or to maintain certain safeguards to operate industries.
