Press Release: Scientific Body’s High Tide Line for TN Wrongly Drawn to Create Real Estate: Coastal Activists

Chennai: Nearly 900 acres of tidal wetlands in two locations have been wrongly identified as land by the National Centre for Sustainable Coastal Management (NCSCM) which got a multi-crore contract to demarcate the High Tide Line for Tamil Nadu under the Coastal Regulation Zone (CRZ) Notification, 2011. This and other inconsistencies were revealed during a ground truthing exercise conducted by the Coastal Resource Centre (CRC). The erroneous demarcation shortchanges fisherfolk by showing tidal waterbodies as developable real estate.

The inconsistencies cast a shadow on NCSCM’s demarcation exercise and the robustness of the verification process by the State and Central Coastal Zone Management Agencies, CRC said. NCSCM’s High Tide Line cannot be relied upon for preparing the State Coastal Zone Management Plans.

NCSCM had denied access to these maps under RTI claiming that disclosure would prejudicially affect their scientific and economic interests. The maps were later accessed through the State Coastal Zone Management Authority.

“Public scrutiny of such foundation data sets is critical as this forms the basis of the CZMP.   An inaccurate HTL can result in a flawed CZMP, and throw open ecologically sensitive areas for development,” said Pooja Kumar of the Coastal Resource Centre.

CRC ground-truthed the HTL data set by zeroing in on locations where prima facie discrepancies were evident.

  • In Karungali, Thiruvallur District, and Yedaiyanthittu Kazhuveli in Kanchipuram/Villupuram districts, the HTL is demarcated within the tidal waterbody thereby reducing the area of water protected by the CRZ Notification. By doing this, nearly 888 acres of new developable real estate has been created in these two locations.

  • The HTL on one arm of the Adyar River was highlighted to show how man-made structures on the river were arbitrarily used to mark the extent of tidal influence. the CRZ limits of Adyar creek stops with the first causeway that the river’s backwaters pass on north of the river mouth.

  • In Athipattu village on Ennore Creek, NCSCM effectively obliterates all evidence of CRZ violation by Hindustan Petroleum (HP). HP has illegally built on a mangrove-fringed tidal creek (CRZ IV and CRZ I under CRZ Notification). By failing to ground-truth or compare it against an earlier, more robust HTL demarcation by the Institute of Remote Sensing, NCSCM’s HTL wrongly uses HP’s violation as the baseline.

Thousands of fisherfolk along the coast of India are facing threats to livelihood and living spaces from various sectors targeting the coast. A robust plan to manage such a contested space is needed to secure the lives and livelihoods of artisanal fishers and protect ecologically sensitive areas. To achieve this, three action points are suggested

  • Ministry of Environment, Forests and Climate change must immediately call for a complete scientific revalidation of the HTL prepared by NCSCM by conducting extensive ground truthing and community consultations
  • HTL prepared by NCSCM in this form must be declared invalid and instructions be passed to all states to pause using this data for preparation of CZMP
  • No project be considered for CRZ Clearance at the state and/or central level until the finalization of a Coastal Zone Management Plan following the guidelines issued in the CRZ 2011 using an accurate, validated HTL.
