Sudan Risk Assessment: District-Level Flood and Service Access Data

Sudan risk assessment indicators aggregated at administrative level 2 (districts) for flood hazard and resilience analysis. Produced by HeiGIT using the GAIA Pipeline, the data integrates WorldPop, OpenStreetMap, and Google Earth Engine sources as of March 2026.

Use Cases

• Flood risk modeling using SDN_ADM2_flood_exposure to identify high-risk districts
• Healthcare accessibility analysis by comparing access_pop_hospitals_30min against total population
• Vulnerability assessment for children using children_u5 and female_u5 demographic counts

Strengths

• Aggregated at Admin Level 2 for localized district-level analysis
• Includes time-based accessibility metrics (30/60/120 min) for healthcare
• Derived from standardized GAIA Pipeline processing

Limitations

• Facility counts are derived from OpenStreetMap, which may have incomplete coverage in rural Sudan
• Demographic accuracy is dependent on WorldPop modeling rather than a recent physical census
