Climate Change and Disaster Preparedness: Building a More Resilient Caribbean

Executive Summary

Key Facts

• Between 2000 and 2023, the Caribbean experienced 793 climate-related events, including tropical storms and floods (Central Bank of Barbados).
• These events caused an estimated US$181.3 billion in damage, largely from storms and hurricanes (Central Bank of Barbados).
• Hurricane Maria caused losses in Dominica equivalent to 226% of GDP in 2017 (Central Bank of Barbados; UNDP).
• UNDP reports that Caribbean countries suffer average storm-related losses equivalent to 17% of GDP in years when they are hit by major storms.
• Coral reefs contribute approximately US$6.2 billion annually to Caribbean economies through tourism, fisheries, and coastal protection, yet 70–90% could be lost by mid-century if current trends continue (UNDP Climate Promise).

The Challenge

Caribbean economies remain heavily dependent on tourism, agriculture, fisheries, and coastal infrastructure. These sectors are highly vulnerable to climate-related disruptions. Rising sea levels threaten airports, ports, hotels, roads, and residential communities situated near coastlines.

The Caribbean Disaster Emergency Management Agency (CDEMA) describes the region as one of the world's most disaster-prone regions, regularly affected by tropical cyclones, storm surges, flooding, and droughts.

For Jamaica, Barbados, Dominica, The Bahamas, and other island states, a single major hurricane can wipe out years of development gains and significantly increase public debt.

Why It Matters

Climate-related disasters create a cycle of destruction and rebuilding that diverts scarce financial resources away from education, healthcare, housing, and economic development.

The World Bank notes that natural disasters can erase an entire year's economic output in some Caribbean countries while further increasing debt burdens.

Disaster preparedness should therefore be viewed not merely as emergency management but as a critical investment in economic resilience and national security.

Potential Benefits

If these recommendations are implemented, the Caribbean could:

• Reduce loss of life during disasters.
• Lower economic recovery costs.
• Protect tourism revenues.
• Improve food and water security.
• Increase investor confidence.
• Strengthen regional cooperation.
• Build long-term climate resilience.

Conclusion

Climate change is no longer a future threat to the Caribbean; it is a present reality. The region's vulnerability demands urgent and coordinated action. Although Caribbean nations contribute little to global emissions, they face some of the world's highest climate risks. By investing in resilient infrastructure, enhancing disaster preparedness, protecting natural ecosystems, and strengthening regional cooperation through CARICOM and CDEMA, the Caribbean can build a safer and more sustainable future.

Policy Recommendations

1. Expand Early Warning Systems: Governments should continue investing in advanced weather forecasting, impact-based forecasting, and real-time emergency communication systems. Research consistently shows that every hour of advanced warning can save lives and reduce economic losses. CARICOM and CDEMA have already begun expanding regional warning capabilities.
2. Climate-Proof Infrastructure: All major infrastructure projects should be designed to withstand future climate conditions rather than historical weather patterns. Priority sectors include roads and bridges, ports and airports, energy networks, hospitals, schools, and water systems.
3. Strengthen Coastal Defences: Governments should prioritise mangrove restoration, coral reef protection, beach nourishment projects, flood barriers, and sustainable coastal development regulations. Nature-based solutions often provide cost-effective protection while preserving biodiversity.
4. Improve Community Preparedness: Every household should be encouraged to maintain disaster supply kits, family emergency plans, evacuation routes, and emergency communication procedures. Prepared communities recover more quickly and experience lower casualty rates.
5. Establish a Caribbean Climate Resilience Fund: CARICOM should consider creating a dedicated regional resilience fund to support disaster recovery, renewable energy projects, climate adaptation programmes, and emergency response capacity building.
6. Accelerate Renewable Energy Adoption: Reducing dependence on imported fossil fuels would improve energy security and reduce recovery costs following disasters.

Discussion Questions

1. Should CARICOM establish a permanent Regional Climate Resilience Fund?
2. Should building codes across the Caribbean be standardised to strengthen hurricane resilience?
3. How can the private sector contribute more effectively to disaster preparedness?
4. What role should the Caribbean diaspora play in funding climate adaptation projects?

These questions are a starting point. Join the discussion below.
