How California Is Winning the Drought

An anonymous reader writes: California is in its fifth year of drought; the past four years have been the driest four-year period in recorded history, and the hottest as well. There have been consistent worries about how it will affect California's residents and its economy — but somehow, the state still seems to be doing fine. "In 2014, the state's economy grew 27 percent faster than the country's economy as a whole — the state has grown faster than the nation every year of the drought. ... The drought has inspired no Dust Bowl-style exodus. California's population has grown faster even as the drought has deepened."

The article makes the case that California is pioneering the water preservation and governance techniques that will be helpful elsewhere in the country if the global climate continues to warm. "The Metropolitan Water District of Southern California now supplies roughly 19 million people in six counties, and it uses slightly less water than it did 25 years ago, when it supplied 15 million people. That savings — more than one billion gallons each day — is enough to supply all of New York City." The article notes, however, that this resilience won't last forever — if the drought continues for several more years, California will be in trouble despite their water-saving tactics.

It depends on how long it lasts.

California often has drought, but this one is different. California has numerous large reservoirs that are nearly drained after three plus years of drought. Groundwater is being rapidly depleted. The state started out with lots of water, but the persistent drought has nearly exhausted the reserves. If the situation doesn't change this winter, the problems we see now will seem trivial. Resilience works up to a point, and then it snaps when certain limits are exceeded. California's water supplies are stretched to the limit right now.

People isn't the issue, farming is

[ebrandsberg]

California cities and towns only get 10% of the water. Farmland gets 80% (or somewhat less depending on how you account for it), yet only produces 2% of the state's GDP. The problem is that they are STILL growing the size of the agriculture sector, planting more almond trees for example, even while the existing almond trees are dying from salt poisoning. The reason the overall GDP hasn't been hurt yet is due to the fact that so much of the water is used for so little of the state's income. When the groundwater is all gone due to lack of planning, things may actually change.

Farmland gets 80%

I don't know where you're getting that number, it's no more than 60% in a good year. In bad years, it's less.....farmers only got ~20% of their normal allocation this year, and have been restricted for the past several years.

The fact that rivers run to the sea isn't really a management problem. There is actually only one river in California without a dam at present, all of the others have controlled levels, hydroelectric generation, and take-outs of much of their water volume for various purposes.

We've already destroyed much of the fisheries and are having trouble recovering them. We might have about 5% of the birds the state once had. The Central Valley, which was swampland only a century ago, has been made a desert. Giant lakes have disappeared.

No surprise if this has changed the weather. A huge heat sink was removed from the environment and there is a perpetual windstorm as cool air is sucked into that valley.

Proper management is not to suck down the remaining 5%, interrupting the flow of rivers to the sea permanently. Proper management is to attach the real economic cost to water delivered to agriculture, rather than to vastly subsidize it.

Yes, this means that farming, and farming jobs, would change. Sorry, you asked more of the land than it could provide forever, your resources have run out, game over.

Desalination requires equipment and sometimes energy, neither of which falls out of the sky.

I'm pretty sure energy does fall out of the sky. Some of these desalination plants use solar power.

Re:Still surprised Cali put plastic in their water

[jklovanc]

They are different plastic. The balls are probably made from ABS. The issue with water bottles is the BPA which softens the plastic. There is no BPA in the shade balls. There are some plastic water bottles that are accepted because they are BPA free.

The overwhelming amount of energy on the planet (well over 99.99999%) does in fact fall out of the sky.

Farmers have responded by pumping water from the aquifers at an unsustainable rate. The farmers with more money have been able to drill deeper wells to get more water leaving poorer farms behind. Yes, they have invested in water saving technologies but they are still using too much.

Desalination is not, however, cheaper than not having almonds. Before we shell out billions (and generate more pollution) legal reforms will be needed to eliminate this "senior water rights" nonsense. Then the costs of any new infrastructure can be spread amongst all water users, according to usage.

Re:There is no reason for any drought to continue

Just let the water evaporate out of it and bulldoze it into a big pile. Then package it and sell it as fancy sea salt.

If the pile gets too big, start re-filling the salt mines.
