Abstract

First introduced by Allan (1997, 1999), the concept of “virtual water” refers to the volume of water used to produce a commodity, good or service. This term can be defined from two distinct perspectives. From the production-site standpoint, the virtual-water content of a product is the volume of freshwater used to produce a product measured at the place where it is produced (Hoekstra and Chapagain 2008). From the consumption-site standpoint, it refers to the volume of water that would have been required to produce a product where it is consumed (Hoekstra and Chapagain 2008).
