1993 Allan: Virtual Water : The amount of water spent to produce a good or service.
2005 Hoekstra-Chapagain: Definition of Water Footprint as an “indicator of consumption”
BUTWATER FOOTPRINT NETWORK: WF as an indicator of “water use that looks at both direct and
indirect water use of a consumer or producer”
