Tanzania Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Tanzania dekadal NDVI indicators aggregated by sub-national administrative units from NASA MODIS collection 6.1. Produced by the World Food Programme (WFP), the data tracks vegetation health through 10-day intervals including current indices, long-term averages, and percentage anomalies. The records are updated as of March 2026.

Use Cases

• Monitoring agricultural health by comparing current NDVI (vim) against long-term averages (vim_lta)
• Identifying drought conditions using the NDVI anomaly percentage (viq)
• Correlating vegetation density with administrative regions using the n_pixels and Pcode columns

Strengths

• Uses NASA MODIS collection 6.1 satellite data
• Includes long-term average (vim_lta) for historical baseline comparison
• Provides pixel counts (n_pixels) to indicate the data density of each aggregate

Limitations

• Aggregated data loses the spatial granularity of raw satellite imagery
• Dependent on WFP-specific administrative boundary definitions
