Use Cases

• Estimate population displacement for emergency response based on the reported affected population count.
• Assess agricultural damage and food security implications based on the reported cropland area affected.
• Map the spatial extent of the flood event for situational awareness using the provided GEOTIFF files.
• Integrate impact metrics into disaster risk models based on the event's date and location.

Strengths

• Provides specific impact metrics: 138,403 people and 45,057 hectares of cropland affected.
• Originates from an operational humanitarian system (WFP ADAM) designed for rapid analysis.
• Data is georeferenced, available in the GEOTIFF format for spatial analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality and spatial resolution require manual inspection.
