Our Challenge
What is the risk reduction role of coastal habitats, and how can we harness that role to create more cost-effective natural solutions to protect people and property from coastal hazards?
Coastal development and climate change are increasing the risks to millions of people from storm surges, sea-level rise and other natural hazards. Coastal habitats like mangroves, coral reefs, and salt marshes can reduce those risks. Hybrid solutions that combine artificial infrastructure with nature may protect lives and property in a more cost-effective way. This SNAPP Team explores how nature can help protect coastal communities.

This work has significantly influenced the way multilateral development banks (the World Bank) and the insurance and reinsurance sector (Swiss Re, Munich Re, Lloyd’s of London, RMS) take into account the risk reduction role of coastal ecosystems.
