Aqueduct baseline water stress

aqueduct_bws · v1.3.0

Retrieves the WRI Aqueduct 4.0 annual baseline water-stress category for an asset location and preserves the upstream response for provenance.

Inputs

• Asset latitude and longitude.
• WRI Aqueduct 4.0 annual analysis using the bws_cat indicator and baseline year.

Calculation

Miombo creates a point geostore for the asset location and requests the Aqueduct annual baseline analysis. The numeric bws_cat value and published label are validated before persistence. Values outside the expected range of −1 to 5 are rejected as an upstream schema or compatibility failure.

Outputs

• baseline water-stress category on the Aqueduct scale;
• the corresponding published label;
• upstream response payload and dataset version for provenance;
• assessment timestamp and signed manifest.

Interpretation

Higher categories indicate greater competition for available renewable water supply. A value of −1 indicates no data and must not be treated as low stress.

Limitations

This is a catchment-scale screening indicator resolved from a point location. It does not measure an operator's actual withdrawal, consumption, permit compliance or local seasonal constraints. Site-level hydrological review remains necessary for operational decisions.
