GLOBIO-aligned Mean Species Abundance screening

globio_msa · v1.0.0

Estimates a land-use-pressure Mean Species Abundance score and affected area using GLOBIO-aligned class fractions, alongside protected-area intersection context.

Inputs

• Asset footprint, or centroid buffer when a footprint is unavailable.
• Land-use class areas within the analysis geometry.
• Registered GLOBIO-aligned MSA fractions by land-use class.
• WDPA protected-area geometry and IUCN category for intersection context.

Calculation

The MSA score is the area-weighted mean of the registered class fractions. MSA loss in square kilometres is the sum of each class area multiplied by one minus its MSA fraction. Protected-area overlap and an IUCN-category-weighted threat proxy are calculated separately.

Outputs

• dimensionless MSA score from 0 to 1;
• estimated MSA loss area in square kilometres;
• protected-area overlap and screening threat proxy;
• geometry basis, source versions and signed manifest.

Limitations

This is a pressure-based screening method, not a species inventory. When verified land-use composition is absent, a representative mining breakdown may be used and is identified as a proxy. The protected-area threat score is not an official IUCN STAR result and must not be represented as one.
