Namibia Subnational NDVI: Dekadal Vegetation Indices and Anomalies

Namibia vegetation health data aggregated by sub-national units from NASA MODIS Collection 6.1 satellite imagery. Maintained by the World Food Programme, the dataset tracks 10-day NDVI values, long-term averages, and anomalies. It provides standardized environmental indicators for administrative regions using WFP Pcode references.

Use Cases

• Monitoring agricultural health by tracking the viq (NDVI anomaly) over time
• Comparing current vegetation levels against the vim_lta (long-term average) to identify drought conditions
• Spatial analysis of vegetation density across different administrative units using Pcode identifiers

Strengths

• Uses NASA MODIS Collection 6.1 high-quality satellite data
• Includes Pcode references for joining with other WFP humanitarian datasets
• Provides n_pixels column to validate the statistical significance of aggregated units

Limitations

• Aggregated at sub-national level, which obscures granular pixel-level spatial variation
• Geographically restricted to Namibia, preventing regional cross-border analysis
