Part 2 Para. 2-6 Research findings of water-scarcity footprint study
Part 3 Para. 7-10 Water-scarce situations around the world
Water-scarcity footprints
1. What is a water-scarcity footprint?
•A water-scarcity footprint is a measurement of water consumption and its effect on the local environment.
