Abstract

Key takeaways


RESCUE is a new ecosystem-specific midpoint indicator for LCAbased water footprint.
- Stress-weighted water volume: potential stress on aquatic ecosystems
- Deprived water volume: the magnitude of deprived water for ecosystems


RESCUE and AWARE are complementary.
- RESCUE can assess the current potential impacts on aquatic
ecosystem.
- AWARE can assess the future pressure where not yet depriving of
ecosystem water requirement.


Temporal variation of the CFs is relevant at some watersheds.
- Inventory needs to be discriminated at monthly level.
