Mauritania Subnational NDVI: Dekadal Vegetation Metrics and Anomalies

Mauritania vegetation health data provided via dekadal (10-day) NDVI indicators aggregated from NASA MODIS collection 6.1 satellite imagery. Produced by the World Food Programme, the records include long-term averages and anomalies for sub-national administrative units to track environmental trends as of March 2026.

Use Cases

• Drought monitoring by tracking negative values in the `viq` anomaly column
• Baseline vegetation analysis using the `vim_lta` long-term average field
• Agricultural productivity mapping by joining `vim` values with Pcode administrative boundaries

Strengths

• Aggregated from NASA MODIS collection 6.1 Aqua and Terra sensors
• Includes Pcode references for interoperability with WFP administrative data
• Provides `n_pixels` count for every aggregate to assess data density

Limitations

• Spatial resolution is limited to administrative unit aggregates rather than raw pixel grids
• Temporal resolution is fixed to 10-day dekads, which may miss rapid environmental changes
