Chad Flood Impact Assessment for September 2025

Chad experienced a flood on September 3, 2025, affecting an estimated 879,498 people and 193,767 hectares of cropland. The data is provided by the World Food Programme's Automated Disaster Analysis and Mapping (ADAM) system, which collects and analyzes geospatial and socio-economic information for humanitarian emergencies. The dataset was last updated on May 21, 2026.

Use Cases

• Modeling population displacement and humanitarian needs based on the estimated number of affected people.
• Assessing agricultural production loss and food security based on the reported cropland damage.
• Conducting geospatial analysis of flood extent and impact zones using the provided GEOTIFF files.
• Supporting rapid disaster response planning for sudden-onset emergencies.

Strengths

• Provides specific impact figures: 879,498 people and 193,767 hectares of cropland affected.
• Sourced from an operational UN system (WFP ADAM) designed for rapid disaster analysis.
• Data is geospatial (GEOTIFF), enabling map-based analysis and integration with other layers.

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.
• The description metadata is limited to a single event; broader context requires external data.
