TAMIL NADU AFFAIRS

Centre for Heat Resilience in Tamil Nadu

  • Set up within the Tamil Nadu Green Climate Company.
  • Part of the U.K. Climate Action for a Resilient Asia Programme.
  • MoU signed in Chennai on 23.11.2025.
  • Project duration: till September 2026.
  • Main Objective: 
  • Develop high-resolution, city-based heat maps for all cities in Tamil Nadu to enable targeted interventions.
  • Implement special heat-reduction projects across Tamil Nadu’s cities and districts.
  • Enhance technical capacity in health, urban development, disaster management sectors.
  • Collect climate-related data and support the government in developing heat-resilience plans.
  • Enhance government and private institutional capacity to manage heat risks scientifically.
  • Collaborative initiative involving Tamil Nadu Government, UN Environment Programme, World Resources Institute, and the U.K. government.
  • Tamil Nadu recognized for climate innovation: first state to establish a State Green Climate Fund and the Tamil Nadu Green Climate Company, and for treating heat waves as state-specific disasters.

Shoreline management plan

  • Tamil Nadu Water Resources Department (WRD) has submitted 41 project proposals worth ₹755 crore to mitigate coastal erosion.
  • WRD seeks funds through the State Disaster Management Authority under the 15th Finance Commission for implementation.
  • Proposals are awaiting approval from the National Disaster Management Authority (NDMA). The projects are likely to take off next year (2026).
  • The projects were prepared based on the draft shoreline management plan and a shoreline changes report from the National Centre for Coastal Research (NCCR).

Vulnerable Districts Identified

  • WRD has listed five coastal districts as high-priority erosion hotspots:
  • Mayiladuthurai 
  • Worst-hit, with nearly 71% of its shoreline facing erosion.
  • Large sections of coast lost in villages like Vanagiri, Naickerkuppam, Pudukuppam (≈50 m lost in a decade)
  • Kanniyakumari.
  • Tiruvallur.
  • Chengalpattu.
  • Chennai.

Status of T.N. Coastline (NCCR Report)

  • The NCCR study analyzed 992 km of the Tamil Nadu coastline.
  • 41% of the coastline is in a stable condition.
  • 39% of the coastline is facing sea erosion risk.
  • Remaining coastline experiences accretion or moderate changes.

Proposed Mitigation Measures

  • WRD plans a combination of nature-based and engineered solutions:
  • Nature-Based Solutions: Beach nourishment, Bio-plantation, Palm bioshields, Coral reefs, Coir structures, Oyster shell beds and “Living shoreline” systems (use natural vegetation and sediment to stabilise coast).
  • Engineered Measures: Installation of geo tubes, Groynes (recommended for densely populated high-risk locations)
