The point isn't about whether cutting home use would make a meaningful difference, just that it's much easier for a household to reduce water use than for a farm. Yes, we need water efficient farms (or, perhaps, farms in places that aren't so hostile to agriculture). But it's very hard to make a farm water efficient.
> But it's very hard to make a farm water efficient. Kind of a sweeping statement. Here's an inexpensive product that reduces water usage by 90%, aimed to farmers and especially good for citrus: http://treetpee.com/ttp-u/
For the record, I've lived in several places with water shortages since I was a teenager. I believe every one placed restrictions on certain activities (no washing car at home, water lawns only on designated days, no water for ornamental ponds, etc.) instead of simply raising the price of water.
I believe California could fix its problem with a lot less trouble by letting the price of water reflect its supply and demand.
