(a) whether the Government has any proposal to demarcate a hazard line
in the coastal areas of the country;
(b) if so, the details thereof;
(c) whether the Government has signed any agreement with the ‘Survey of
India’ in this regard;
(d) if so, the details thereof; and
(e) the steps taken by the Government in this regard?
MINISTER OF STATE (INDEPENDENT CHARGE) FOR ENVIRONMENT AND FORESTS
(SHRIMATI JATANTHI NATARAJAN)
(a): Yes, Sir.
(b): The Ministry has initiated a project for demarcation of hazard line in the
coastal areas of the country taking into account flooding due to sea level rise,
tides, waves and shoreline change. The hazard line mapping is one of the components
under the Integrated Coastal Zone Management Project. The hazard line drawn along
the coastline will be used for planning and regulating developmental activities
along the coastal areas.
(c) : Yes, Sir.
(d) : The Ministry of Environment and Forests (MoEF) has signed a Memorandum of
Understanding on 12th May, 2010 with the Survey of India for mapping, delineation
and demarcation of the hazard line along India’s 7 km wide coastal belt including
the inter tidal area for the entire mainland of the coastal areas taking into
account tides, waves, sea level rise and shoreline changes.
(e) : The Stereo Digital Aerial Photography (SDAP) would cover the 11000 km arc
coastline from Gujarat to West Bengal with an area of 60,000 sq kms. The hazard
line for the mainland coast of India will be mapped, delineated and demarcated on
the ground over a period of five years. This will include the collection and
presentation of data identifying flood lines over the last 40 years (which
includes sea level rise impacts) and a prediction of erosions to take place
over the next 100 years. The hazard maps would be prepared in 1:10,000 scale
and after ground verification, pillars would be erected demarcating the hazard
line.
