Bhutan Risk Assessment Indicators: District-Level Flood and Accessibility Data

HeiGIT produced these risk assessment indicators for Bhutan at the admin level 2 (district) scale, last updated in March 2026. The data aggregates demographic, infrastructure, and accessibility metrics from WorldPop and OpenStreetMap to facilitate structured flood hazard assessments.

Use Cases

• Modeling flood impact on vulnerable populations using BTN_ADM2_flood_exposure and children_u5
• Evaluating healthcare infrastructure gaps using access_pop_hospitals_30min and primary_healthcare_count
• Planning emergency response routes based on access_pop_primary_healthcare_1h metrics

Strengths

• Aggregated at admin level 2 for localized disaster management
• Includes travel-time metrics derived from openrouteservice
• Combines demographic data from WorldPop with infrastructure from OpenStreetMap

Limitations

• Facility counts like hospitals_count are limited by the completeness of OpenStreetMap data in Bhutan
• Aggregated district-level data may obscure high-risk pockets within a single district
