Additional Metric Notes

ACT-D stage: Assess Maturity stage: Developing Metric Contribution to Action: Comparing availability to use helps prevent overconsumption and ensures operations remain within sustainable water limits. Observations/Sucesses/Challenges: > Global models exist, but local variations in hydrology, climate, and infrastructure can affect accuracy. > Does not reflect seasonal variability > If a company operates across multiple watersheds, determining “total availability” for reporting can be complex. > High availability does not always mean low risk (e.g., pollution, regulatory restrictions, or competing demands may still pose challenges). > Collective action and data-sharing across major water users in the catchment is essential for feasibility and success.
