Yet liberal states tend to be net contributors to the federal budget (we get back less than we put in) while conservative states are net users (they take more than they put in).
I imagine the conservative states would gladly trade you their takers in exchange for some of your producers.

It's only 2016. Why aren't they de-salinating sea water using today's technology.

Where does the water trickle down to? The water in those rice fields just flows back to the ocean via the Sacramento river, and is not re-used or captured. It is also contaminated.

They may use more water in aggregate on Almonds, but I think that is because they produce a lot more
quote:I think it takes over a gallon to grow just one almond. I don't know how that compares to an equivalent amount of rice, but that seems like a lot. I believe almonds do make a lot of money per gallon of water, though. They feed the alfalfa to cows, which I believe is a very poor return per gallon.
. I don't think Almond tress are nearly as water intensive as rice and alfalfa.

The rice water will evaporate a good bit, but a vast majority of the flood water is re-used.
You sure?

till, you need a lot of water to grow it. Rice’s per-acre water needs, flooded fields and all, actually aren’t off the charts relative to other crops, but they are higher. Rice on average requires 5.1 feet of water applied per growing season, edging out alfalfa as the most water-intensive of major California crops. Multiply that times the 550,000 acres planted in a normal year, and you get 2.8 million acre-feet of water, or about 6 percent of the state's total consumption
quote:
That overstates rice's take a bit, as some of the water is reused after it sloshes off the fields or soaks into the ground. But it's clear that growing rice simply wouldn’t work in California without a lot of water.
quote:
One oft-stated reason for these decisions is that rice farmers are already fallowing about 25 percent of their acreage because of the drought, and cutting back planting even more than that would hurt local businesses that revolve around rice growing. As a matter of local politics and just plain neighborliness, this makes sense. As far as statewide economics, not so much. In California, rice is planted from airplanes and harvested with giant machines -- it’s not a labor-intensive crop. When Peter Gleick of California’s Pacific Institute set out a decade ago to calculate how many jobs were created relative to the amount of water used in various agricultural and industrial pursuits, rice came in dead last at one job per 1,000 acre-feet of water.

That's not true no matter how many times it is said in this thread.
If 70% of your urban water use is for lawns and landscaping, you don't really have a water crisis of any type. They don't have the water supply necessary to cover their wants, but the water available for their needs is more than enough.

You realize there is a big difference between salt water and fresh water, right? Desalination is very expensive.

Completely different process that would need brand new treatment plants that are very very expensive.

that is one way they do it, yes, but it isn't very efficient

Lol at trying to grow a lawn in the desert you stupid fricks.
Plant a couple of cactuses and groom the dirt and call it a day.

But they (well, one farmer) said if they used another type of hay, they cows go sick, didn't do well and were in poorer health all around. Or something to that effect.

Ocean water desalination doesn’t pencil out. It’s far too expensive to produce potable water from seawater — about $2,000 an acre foot, compared to about $1,000 an acre foot for imported water. It requires a tremendous amount of energy to purify saltwater. And there are potentially serious environmental impacts from sucking in millions of gallons of ocean water and pumping the leftover brine back into the ocean.
So ... basically, it would be cheaper to import water from somewhere else than to desal.
