I wish there was some way to change prices to alter demand. Maybe a "task force of thought leaders" can crack open an Econ 101 textbook and look at the supply and demand curve on the first page.

Sorry for the sarcasm, I'm just disappointed in the "reach for regulation first" approach to dealing with shortages.

Maybe I skimmed the article a bit fast, but I saw no mention of desalination plants, which are the obvious solution (though expensive and as far as I'm aware not implemented yet).

It's not going to be easy to build few of them in less than a year.

I've seen complaints that it has a big environmental impact too.

So what happens when they run out of water? Are there water sources that are just undrinkable that can be cleaned up; similar to fracking now being cheap enough to compete with OPEC is there no water or just no drinkable water? Can they just "ship" or "pipe" the water in from neighboring states or are they too on the edge of a draught. Is this country-wide, just Western states, or just California and can other states…

A lot of water in California goes to farming. They'll have to close farms, which will drive up prices of produce.

About HALF of produce consumed in US comes central part of California. Exact ratio depends on the type of crop though. And it takes a LOT of water for all the crop.

So it's not really the green lawns or swimming pools.

California's power grid is already stressed. Desalination takes a lot of power, so any new plants will probably have to install new power generation as well.

If I were building a desalination plant I'd put the generator on site - why waste money on transmission losses?

Natural gas generators are clean enough that I don't think it would be a big problem putting one by the ocean.

My understanding is that under most scenarios water for humans is fine, but agriculture will be totally dead in California.

Ahh, ok they hinted at that in the article but for some reason it didn't click in my head. I wonder if the farmers will just move to neighboring states (not that it's easy to pick up and move a farm....) losing farms in California would be a huge loss:

> California produces a sizable majority of many American fruits, vegetables, and nuts: 99 percent of artichokes, 99 percent of walnuts, 97 percent of kiwis, 97 percent of plums, 95 percent of celery, 95 percent of garlic, 89 percent of cauliflower, 71 percent of spinach, and 69 percent of carrots (and the list [1] goes on and on).

You're right, if people can't afford water to drink, they're clearly not valuable enough to live. If a farm can't afford water for crops, the crops weren't profitable enough to grow anyway. And if the rest of the nation can't afford food since some foods will be scarce without California farms, they should just be more productive. No need for regulation!

My understanding is that under most scenarios water for humans is fine, but agriculture will be totally dead in California.

Which in turn means US will have to do with about 50% less vegetable/crop to consume.

Which would still be absolutely catastrophic considering how much of US (and world, for that matter) supplies of produce come from CA.

I don't think this will work for the lion's share of the water consumption, irrigation - way to expensive to be able to sell the harvest at competitive prices.

A historical view: http://www.city-journal.org/2015/25_1_california-drought.htm...

That reads like it was written by a clueless reactionary. Draining reservoirs didn't cause the drought. It caused the water supply to dry up sooner in the midst of a drought.

> Then they alleged that global warming, not their own foolish policies, had caused the current crisis.

One of the most brain-dead sentences I've ever read. No one is claiming that global warming is responsible for the reservoirs being depleted. They are claiming that global warming is responsible for the fact that the reservoirs have not been replenished by rain and snow melt. It is a subtle, but extremely important difference.
