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”
MilestonesVirtual Footprint
Concepts Applications Proposal
VSIndustry as Producer and Consumer
Population as Producer and Consumer
Difference between Virtual and Water Footprint??
Wide definition- Wide use Allan (1993): Visualize water as Geopolitical Factor. Hoekstra (2003): Policy Indicator
Use as Synonyms
