Solomon Islands: Dekadal NDVI and Vegetation Anomalies by Sub-National Unit

WFP-produced dekadal NDVI indicators for the Solomon Islands, derived from NASA MODIS collection 6.1 satellite data. The data is aggregated at sub-national administrative levels and includes long-term averages and percentage anomalies. It provides standardized vegetation health metrics for environmental monitoring as of March 2026.

Use Cases

• Analyzing vegetation health trends using the vim and viq columns
• Drought monitoring by comparing current NDVI (vim) against the long-term average (vim_lta)
• Validating administrative unit data quality using the n_pixels count

Strengths

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

Limitations

• Geographically restricted to Solomon Islands
• Aggregated data loses fine-grained spatial resolution present in raw satellite imagery
• Dependent on WFP administrative boundary definitions which may change over time
