ECOSYSTEM-BASED ADAPTATION (EBA)

"ECOSYSTEM-BASED ADAPTATION (EBA) offers a sustainable and resilient alternative to traditional coastal protection infrastructure." Discuss with reference to India's coastal climate adaptation strategy.

Model Answer

Introduction

  • India's coastline faces growing threats from sealevel rise, cyclones, storm surges, and coastal erosion due to climate change.
  • While traditional infrastructure such as seawalls remains important, Ecosystem-based Adaptation (EbA) is emerging as a sustainable approach for enhancing climate resilience.

Role of EbA in Coastal Adaptation

Natural Protection Against Climate Hazards

  • Mangroves reduce storm surges and coastal flooding.
  • Coral reefs dissipate wave energy.
  • Seagrass meadows stabilize sediments.

Ecological Benefits

  • Conservation of biodiversity.
  • Carbon sequestration through Blue Carbon ecosystems.
  • Improved ecosystem health.

Socio-Economic Benefits

  • Supports fisheries and tourism.
  • Strengthens livelihood security.
  • Enhances community resilience.

Evidence from India

  • Bhitarkanika mangroves reduced impacts of Cyclone Dana.
  • Sundarbans restoration programme helped reduce cyclone damage while supporting local livelihoods.
  • MISHTI aims to restore 540 sq. km. of mangroves across nine States.

Challenges

  • Preference for visible grey infrastructure.
  • Fragmented institutional responsibilities.
  • Weak monitoring of adaptation outcomes.
  • Inadequate recognition of EbA in policy frameworks.

Way Forward

  • Mainstream EbA into coastal planning.
  • Increase funding and climate finance.
  • Develop clear monitoring frameworks.
  • Promote community participation.
  • Adopt a hybrid model combining green and grey infrastructure.

Conclusion

  • Ecosystem-based Adaptation provides a cost-effective, sustainable, and socially inclusive pathway for coastal resilience.
  • Integrating EbA into India's climate adaptation strategy can strengthen both environmental security and long-term development outcomes.
