#LearnSustainability: Water footprint

The water footprint of a person, community, company or country is the total fresh water used to produce the goods and services consumed. The Dutch professor Arjen Hoekstra coined the concept in 2002 and since then it's been used to extract data about the water footprint in different countries.

Wasteful consumption of fresh water is a major threat to the planet. Water resources used to produce goods and services have a global cost over which we must have a firm grip, otherwise we run the huge risk of wasting a scarce and necessary resource.
