Abstract :
[en] The renewability of freshwater can only be assessed at a local(regional) scale. Water consumption should not be confused with water production or withdrawals. Globally, about 30% of the available and renewable freshwater is 'used' while less than 15% is actually 'consumed'. Water shortages are due to the uneven spatial and temporal distributions of freshwater conjugated to inadequate local management. Water issues are not only quantity problems but also a quality problem. Groundwater reserves are 77 x surface-water reserves. Rigorous LCA analysis and water footprint assessments remain challenging.
