Malawi Risk Assessment: District-Level Flood and Cyclone Indicators

Malawi risk indicators at admin level 2 (districts) produced by HeiGIT in 2026. The data integrates WorldPop, OpenStreetMap, and Google Earth Engine sources to quantify flood and cyclone exposure alongside demographic and infrastructure metrics.

Use Cases

• Evaluating healthcare resilience by comparing access_pop_hospitals_30min against elderly population counts
• Disaster preparedness planning using flood_exposure and cyclone_exposure indicators
• Resource allocation based on education_count and primary_healthcare_count per district

Strengths

• Aggregated at admin level 2 for district-level planning
• Integrates multi-source data from WorldPop and OpenStreetMap
• Includes specific travel-time accessibility metrics (30min/1h/2h)

Limitations

• Potential undercounting of facilities in districts with low OpenStreetMap contributor activity
• District-level aggregation masks localized risk variations within administrative boundaries
