Vanuatu Risk Assessment Indicators: District-Level Hazard and Access Data

HeiGIT generated these risk assessment indicators for Vanuatu at the administrative level 2 to facilitate structured flood and cyclone hazard analysis. The data integrates population figures from WorldPop, infrastructure from OpenStreetMap, and travel times from openrouteservice to quantify district-level vulnerability.

Use Cases

• Evaluating disaster resilience by analyzing the access_pop_hospitals_30min column to identify underserved districts
• Planning emergency evacuations using children_u5 and elderly counts to locate high-need populations
• Assessing infrastructure capacity for recovery efforts using education_count and primary_healthcare_count

Strengths

• Standardized ADM2_PCODE for integration with HDX COD-AB boundaries
• Includes travel-time accessibility metrics derived from openrouteservice
• Integrates three distinct primary data sources: WorldPop, OSM, and Google Earth Engine

Limitations

• Potential under-representation of facilities in remote areas due to reliance on OpenStreetMap
• Aggregation at admin level 2 may obscure hyper-local risk variations
