Stats from Fred Pearce's Book "When the Rivers Run Dry", 2007, Random House. Mr Pearce also has other water related books published by CSIRO.
There will be a slight variation to these figures subject to specific growing circumstances but, at the very least, they are considered to be an accurate guesstimate to water usage. The CSIRO also produces a very similar set of figures for major crops.

Fascinating figures, mg. And 4 litres to flush a Sicilian toilet!!
wow...i'll have to share that with karate_man... he is really into the environment at the moment, maybe i should buy him a greenpeace membership...smiles... we take water for granted here in aus, those figures are really quite frightening
I figure that even if they were 50% out, it still gives me great pause for thought - and more determination not to buy Australian rice again :-)
Like the greenpeace membership idea. Is there a local urban landcare group he could help out with (if he is into such things)?
