The water footprint is an indicator of water use that includes both direct and indirect water use of a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. Water use is measured in water volume consumed (evaporated) and/or polluted per unit of time. A water footprint can be calculated for any well-defined group of consumers (e.g. an individual, family, village, city, province, state or nation) or producers (e.g. a public organization, private enterprise or economic sector). The water footprint is a geographically explicit indicator, not only showing volumes of water use and pollution, but also the locations.[1]. However, the water footprint does not provide information on how the embedded water is contributing to water stress or environmental impacts. The water footprint concept was introduced in 2002 by A.Y. Hoekstra from UNESCO-IHE as an alternative indicator of water use.[2] La voce "Water Footprint" nella WikiPedia Italiana NON ESISTE.
