Barbados Risk Assessment Indicators for Flood Hazards at Admin Level 2

HeiGIT's GAIA Pipeline integrates open data from WorldPop, OpenStreetMap, and Google Earth Engine to produce seven indicator layers for disaster risk analysis. These layers include demographic, environmental, infrastructure, accessibility, and hazard-related data aggregated for Barbados's administrative level 2 districts. The dataset was last updated on 2026-04-13 and is licensed under CC-BY-SA-4.0.

Use Cases

• Modeling flood exposure and vulnerability based on the BRB_ADM2_flood_exposure and BRB_ADM2_vulnerability layers.
• Assessing population access to healthcare and education services based on travel time and distance indicators.
• Analyzing demographic risk factors, such as the population of children and elderly, for targeted disaster preparedness.
• Evaluating district-level coping capacity by combining facility counts and population access metrics.

Strengths

• Provides seven distinct indicator layers covering demographics, facilities, access, vulnerability, and flood exposure.
• Integrates multiple authoritative open data sources, including WorldPop and OpenStreetMap.
• Data is aggregated to a standardized administrative boundary (admin level 2) using HDX COD-AB.
• Includes specific travel-time and distance-based metrics for access to services.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation for the 'Rural Population' layer is incomplete.
• Freshness should be verified as the last update date is in the future (2026-04-13).
