Zambia Risk Assessment Indicators: District-Level Flood and Infrastructure Data

HeiGIT developed this dataset of risk assessment indicators for Zambia at the administrative level 2 (district) to facilitate flood hazard analysis. It integrates demographic, infrastructure, and accessibility metrics derived from WorldPop, OpenStreetMap, and Google Earth Engine. The data is structured to support disaster resilience analysis through standardized administrative boundaries.

Use Cases

• Assessing healthcare gaps by analyzing access_pop_primary_healthcare_30min across districts
• Disaster preparedness planning using flood_exposure indicators
• Demographic vulnerability mapping using children_u5 and elderly counts

Strengths

• Aggregated at administrative level 2 for localized district analysis
• Includes specific travel-time accessibility metrics for healthcare and education
• Integrates multi-source data from WorldPop, OSM, and Google Earth Engine

Limitations

• Facility counts are limited by the completeness of OpenStreetMap data in rural Zambia
• Temporal alignment between WorldPop demographics and OSM infrastructure data may vary
