报告摘要

Vision and Purpose

Establish a regional, inclusive, and reliable multi-hazard impact-based early warning system (MHEWS) to protect lives, livelihoods, and assets in the Caribbean.
Address challenges like climate change, economic losses, and institutional fragmentation through harmonized strategies.

Strategic Pillars

Risk Knowledge: Improve data collection, sharing, and analysis (e.g., geospatial platforms, vulnerability mapping).
Hazard Monitoring and Forecasting: Enhance hydrometeorological, health, and air quality monitoring (e.g., radar networks, precipitation grids).
Early Warning and Communication: Standardize warnings, leverage technology (e.g., Common Alerting Protocol, regional alert systems), and ensure inclusivity.
Preparedness and Response: Strengthen community-based planning and business continuity measures (e.g., flood forecasts, health impact integration).

Strategic Initiatives

10 key initiatives across the four pillars, building regional capacities while addressing climate and socioeconomic risks.

Economic Benefits

Cost-Benefit Ratio: ~$4–6M investment per country yields ~$12–24M annual benefits, with a regional approach generating twice the returns.
Key Benefits: Reduced fatalities (300–600/year), asset damage savings ($30M–$40M/year), and sectoral productivity gains.

Implementation Approach

Phased Approach: Short-term wins, medium-term capacity building, and long-term system integration.
Key Ingredients: Enabling policy, private sector engagement, inclusive planning, and sustainable financing.
