Botswana Risk Assessment Indicators: District-Level Flood and Demographic Data

Botswana risk assessment indicators aggregated at the administrative level 2 (districts) provide a basis for flood hazard and resilience analysis as of March 2026. Produced by HeiGIT, the data integrates demographic, infrastructure, and accessibility metrics derived from WorldPop, OpenStreetMap, and Google Earth Engine.

Use Cases

• Evaluating emergency medical response by analyzing access_pop_hospitals_30min across different districts
• Prioritizing flood mitigation efforts by correlating BWA_ADM2_flood_exposure with elderly population counts
• Assessing educational needs by comparing education_count against pop_u15 totals

Strengths

• Aggregates data from 4+ primary sources including WorldPop, OSM, and Google Earth Engine
• Provides specific travel-time accessibility metrics for hospitals and schools
• Includes age-and-gender-disaggregated demographic data for vulnerable groups

Limitations

• Potential under-representation of facilities in rural areas due to OpenStreetMap crowdsourcing bias
• Temporal staleness of underlying WorldPop or OSM data may vary by region
