ENCORE-aligned ecosystem dependency assessment

encore_dependency · v1.2.0

Maps mining activity to ecosystem-service dependencies and adjusts relevant dependency exposure using current water-stress and land-loss evidence.

Inputs

• Asset commodity and mining activity context.
• Registered ENCORE-aligned mining dependency matrix.
• Latest baseline water-stress category, when available.
• Latest tree-cover-loss assessment, when available.

Calculation

Each matrix dependency starts with its registered base score. Freshwater-use dependencies are amplified by water stress up to a 1.5 multiplier. Land-use dependencies are amplified by assessed loss up to a 1.3 multiplier. The aggregate is a base-score-weighted mean of contextual dependency scores.

Outputs

• ecosystem services, categories, processes and dependency levels;
• base and contextual scores with rationale;
• aggregate ecosystem-service risk score;
• source manifest references and signed assessment manifest.

Limitations

This method screens dependency exposure; it does not measure ecosystem condition or a site's actual operational dependence. Matrix mappings are representative of mining activities and should be refined with asset-specific process and supply-chain evidence where material.
