Californians
are experiencing their third year of drought. Headlines read: "Current
California Drought Is Driest In State's History; Scientists Fear 'Megadroughts'
On Their Way." "Global Warming Upped Heat Driving California's
Drought." Then there are scientific claims such as, "There's a
rapidly growing body of scientific research finding that California is in the
midst of its worst drought in over a millennium (and) global warming has made
the drought worse." A Stanford University study said, "Human-caused
climate change helped fuel the current California drought." One news
outlet summarized the conclusions of a group of environmentalists this way:
"California's severe and ongoing drought is just a taste of the dry years
to come, thanks to global warming."
Let's examine a
few drought facts.
California
experienced eight major droughts in the 20th century, according to the U.S.
Geological Survey. They ranged from two years to as long as nine years, such as
that which occurred from 1928 to 1937. In the previous century, there was the
bitter drought of 1862-65, which was a catastrophe for the state of California
— made worse by a smallpox epidemic. Scott Stine — professor of geography and
environmental studies at California State University, East Bay — said that all
of these modern droughts were minor compared with California's ancient droughts
of 850 to 1090 and 1140 to 1320. One wonders whether California Gov. Jerry
Brown and his cadre of environmental extremists would attribute those ancient
droughts to man-made global warming.
A large part of
California's water problem has economic roots. Whenever there's a shortage of
anything — whether it's water or seats at a baseball stadium — our first
suspicion should be that the price is too low. California agriculture consumes
about 80 percent of the state's delivered water, and it has been exempted from
many of California's new restrictions. On top of that, agricultural water users
pay a much lower price than residential users. In other words, California's
farmers are being heavily subsidized.
The Imperial
Valley, located in the southeastern part of the state, is geologically a
desert. Nonetheless, its farmers grow large quantities of potatoes,
cauliflower, sweet corn, broccoli and onions. These crops would not be produced
without there being subsidized irrigation and other state and federal
subsidies. I need someone to show me that there is such a desperate need for
somewhere to grow potatoes, corn and other crops that we need to subsidize
making a desert bloom.
Western water
is mostly controlled by the U.S. Congress and its Bureau of Reclamation.
Through lobbying efforts, the Bureau of Reclamation is controlled by growers
and other special interests. Water is distributed in California and other
Western states not by market prices but by the political process. Agricultural
interests have disproportionate political power. That means that agricultural
interests receive taxpayer-financed handouts.
California
farmers argue that without federal and state government subsidies, crops could
not be grown in desert areas. That's a foolish, self-serving argument. If I
were an Alaskan wanting to use government subsidies to build hothouses to grow
navel oranges, I could use the same argument: Without government subsidies, I
couldn't grow navel oranges in Alaska.
Some of
California's water conservation regulations are mindless. It is illegal for
servers in bars, restaurants and cafeterias to serve water unless customers
ask. The amount of water that people drink per day is a trivial part of total
water consumption. Estimates vary, but each person consumes 80 to 100 gallons
of water per day flushing toilets, bathing and for other residential purposes.
Another
California water conservation effort is "drought shaming." That's
when vigilantes call water utility hotlines to snitch on their neighbors who
are watering lawns, washing cars or filling pools. One wonders whether there
might arise an anti-vigilante movement to punish the vigilantes.
The bottom line
for solving California's water problem is that there needs to be a move toward
a market-oriented method for the distribution of water. Government management
has been a failure.
