Dugong Centre CRZ Issues: Thanjavur Alert

DUGONG CONSERVATION CENTRE AND COASTAL REGULATION ISSUES

Why in the News?

  • Union Expert Appraisal Committee (EAC) asked Tamil Nadu government to revise the International Dugong Conservation Centre
  • Environmental clearance concerns raised due to construction in ecologically sensitive coastal areas.
  • Coastal Regulation Zone (CRZ) violations flagged in the proposed project design.

Dugong Centre CRZ Issues: Thanjavur Alert

EAC OBSERVATIONS AND KEY CONCERNS

  • Ecologically sensitive location: The Manora site overlaps CRZ-III No Development Zone and CRZ-I areas containing mangroves and seagrass meadows.
  • Concrete-heavy construction: Nearly 22,000 square metres of the project within restricted zones relies on cement and concrete structures.
  • Low-impact mismatch: Infrastructure meant for environmental awareness and conservation contradicts principles of minimal ecological disturbance.
  • Pristine coastal ecosystem: The project area includes mudflats, mangroves, and seagrasses, which support fragile marine biodiversity.
  • Conditional conservation support: While acknowledging dugongs as critically endangered, the EAC stressed conservation cannot justify environmental degradation.

RECOMMENDATIONS AND SUGGESTED ALTERNATIVES

  • Substantial redesign demanded: The State was asked to revise the project layout to reduce its environmental footprint.
  • Eco-friendly construction methods: The EAC suggested timber-based, prefabricated, or composite materials instead of concrete.
  • Relocation of infrastructure: Advisories were issued to shift facilities outside the No Development Zone wherever possible.
  • Nature-sensitive architecture: Structures should blend with natural surroundings rather than impose permanent rigid designs.
  • Learning from best practices: Tamil Nadu was asked to study sustainable conservation centres implemented elsewhere in India.

DUGONG CONSERVATION AND COASTAL ZONE MANAGEMENT

●      Keystone marine species: Dugongs play a vital role in maintaining seagrass ecosystem health and coastal food chains.

●      Purpose of CRZ framework: Coastal Regulation Zones aim to balance development needs with environmental protection.

●      Importance of coastal habitats: Mangroves and seagrasses act as carbon sinks, erosion barriers, and biodiversity hotspots.

●      Conservation–development dilemma: Wildlife projects often fail when infrastructure planning ignores ecological limits.

●      Sustainable conservation model: Long-term marine protection requires low-impact infrastructure aligned with ecosystem resilience.
