Planetary boundaries for water – A review

The water planetary boundary has been proposed to determine limits for a sustainable anthropogenic appropriation of freshwater. Aim of the present research was to summarise the water planetary boundary’s development status and applications including its integration into Life Cycle Assessment and Env...
