Nigeria Flood Impact Assessment for September 2025

Nigeria experienced a flood event on September 22, 2025. The dataset, produced by the World Food Programme's Automated Disaster Analysis and Mapping (ADAM) system, provides geospatial analysis of the event's impact on population and agriculture. It estimates the flood affected approximately 1,814,776 people and 264,965 hectares of cropland.

Use Cases

• Estimate population displacement and humanitarian needs based on the reported affected population count.
• Assess agricultural damage and food security implications based on the reported cropland area affected.
• Model flood extent and severity using the provided geospatial (GEOTIFF) data layers.
• Support post-disaster recovery planning by quantifying the scale of impact on people and land.

Strengths

• Provides specific impact estimates for population (1,814,776 people) and cropland (264,965 hectares).
• Originates from an operational humanitarian analysis system (WFP ADAM), suggesting a structured collection methodology.
• Data is georeferenced, available in GEOTIFF format for spatial analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description metadata is limited to high-level impact figures; underlying data granularity is unknown.
