Metric Contribution to Action
Comparing availability to use helps prevent overconsumption and ensures operations remain within sustainable water limits.
Observations, Successes and 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.
