The water used to farm isn't critial enough to anyone's daily life to be fought over. Specific areas might suffer from drought but not the entire country.
I'm not trying to suggest that if normal sources of water magically disappeared then things would be okay. I'm just saying that under possible circumstances there won't be any reason to fight to the death over water. Because of the desalination option, water shortages wouldn't be able to threaten anyone's life, only force businesses to adapt or move.
Also according to http://www.waterfootprint.org/?page=files/Animal-products even without any efficiency improvements caused by high water costs, pig would be $3 a pound more expensive and cow would be $7 a pound more. Easily afforded.
