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.
