Description

Demonstration Case Name

Multi-hazards in Senegal (transferability case)

Dataset Name/Title

Exposure to CDHW - Senegal, 5-, 10-, 20-year RP

Dataset Description

Exposure analysis of administrative units and population

Key Methodologies

The Severity of Compound Drought and Heatwave Events (https://doi.org/10.5281/zenodo.15211948) was computed for the last 5, 10 and 20 years and reclassified into four classes:  0 - insignificant CDHW (below 70th percentile,  below 13 degrees), 1 - mild (above 70th percentile, 13 degrees), 2 - moderate (above 90th percentile, 23 degrees), 3 - severe (above 95th percentile, 30 degrees).

The exposure analysis was conducted at riskchanges.org

Temporal Domain

2003-2023 for hazards, 2020 population, 2025 administrative units

Spatial Domain

Senegal, GeoTiff files EPSG:4326, shape files EPSG:3857

Key Variables/Indicators
  • Severity of CDHW events per four classes
  • Exposed people per Administrative unit
  • Exposed area per Administrative unit 

Data Format

The hazard data is in GeoTiff files; exposure analysis results are zip files containing ESRI Shapefiles.

Source Data
