I think the question is how much less water would be used with a modern irrigation system rather than flood irrigation.

  Ostensibly you could grow hydroponically and have very little waste but order of magnitude cost increase in power needs. Every other solution falls in between I guess.

    Electricity is orders of magnitude easier to move than water, and its price is dropping too.
