Wildfire Density in Bejaia and Tizi Ouzou, Algeria, August 2021

A geospatial dataset from the United Nations Satellite Centre (UNOSAT) mapping fire hotspot density detected by VIIRS sensors between August 9 and 16, 2021. It reports 1,502 hotspots in Bejaia and 1,733 in Tizi Ouzou, with an estimated 210,000 people living near fire-affected areas. This preliminary analysis from August 2021 has not been field-validated.

Use Cases

• Mapping wildfire density based on VIIRS satellite detections.
• Estimating population exposure to wildfires based on WorldPop demographic data.
• Analyzing temporal fire patterns based on the reported peak between August 10-13, 2021.
• Assessing regional wildfire severity based on hotspot counts per administrative area (wilaya).

Strengths

• Provides specific hotspot counts for two Algerian wilayas: 1,502 for Bejaia and 1,733 for Tizi Ouzou.
• Includes a population exposure estimate of approximately 210,000 people.
• Identifies a specific temporal peak for fire activity between August 10 and 13, 2021.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is described as a preliminary analysis and has not been field-validated.
