Eritrea Subnational NDVI: Dekadal Vegetation Indicators and Anomalies

A source of dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for Eritrea, aggregated by sub-national administrative units using NASA MODIS collection 6.1 satellite data. Produced by the World Food Programme (WFP), the data tracks vegetation health through current values, long-term averages, and percentage anomalies. The records are mapped to specific WFP administrative boundaries using standardized Pcode references.

Use Cases

• Monitoring agricultural health by comparing vim against vim_lta to identify drought-affected regions
• Analyzing seasonal vegetation trends using the viq anomaly percentage to trigger early warning systems
• Correlating vegetation density with food security indicators by joining records via Pcode administrative keys

Strengths

• Uses NASA MODIS collection 6.1 high-resolution satellite data
• Includes Pcode references for seamless joining with other WFP humanitarian datasets
• Provides n_pixels column to verify the data density of each administrative aggregate

Limitations

• Geographically restricted to Eritrea
• Aggregated format obscures pixel-level spatial variations within administrative units
• Dependent on cloud-free satellite observations for accurate NDVI readings
