Summary: The global water crisis and the prospects for future water resources is forcing adjustments for how we measure its use, how it is valued, and how (and to whom) it is allocated. In this fifth episode of a multi-part series on water, host Peter Neill suggests that in order to solve the fresh water problem we must first understand how much water is available and how it is being used—by understanding the “watermark” measures of use at every level of supply and demand; and he returns to the Water Footprint Network in order to outline their new international classification system for freshwater-related ecosystem services.
