Central African Republic Subnational NDVI and Vegetation Anomalies

Giving access to dekadal (10-day) Normalized Difference Vegetation Index (NDVI) indicators for the Central African Republic, aggregated by sub-national administrative units. Produced by the World Food Programme (WFP) using NASA MODIS collection 6.1 satellite data, it includes long-term averages and percentage anomalies. The records are current as of March 2026.

Use Cases

• Monitoring agricultural health by comparing vim against vim_lta to identify drought conditions
• Analyzing vegetation trends over time using the viq anomaly percentage to detect environmental shifts
• Correlating food security outcomes with vegetation density using the Pcode join keys

Strengths

• Uses NASA MODIS collection 6.1 high-quality satellite imagery
• Includes Pcode references for easy joining with other WFP humanitarian datasets
• Provides n_pixels to indicate the statistical weight of each aggregate

Limitations

• Aggregated at sub-national levels, losing granular pixel-level spatial variance
• Dependent on cloud-free satellite observations for accurate NDVI readings
