If a drought in California stretched on for 72 years, it wouldn't be a complete disaster, reported Bettina Boxall in the Los Angeles Times. According to computer modeling research by a group of UC and CSU scientists, the California economy would not collapse and agriculture would shrink, but not disappear.
"The results were surprising," said Jay Lund, director of the Center for Watershed Sciences at UC Davis. "California has a remarkable ability to weather extreme and prolonged droughts from an economic perspective."
Dan Sumner, director of the UC Agricultural Issues Center, said the state's 8 million acres of irrigated cropland could be cut in half. Farmers would grow less "low-value crops" like cotton and alfalfa and use reduced water supplies for growing fruits, nuts and vegetables.
Land that had been farmed would revert to scrub or be dry-farmed with wheat or other crops that were common before the federal government built a system to channel water to the valley.
"In a sense, we move back to the future," Sumner said.
Some farm communities would turn into ghost towns, the article said. "For a while, poor people would get a lot poorer throughout the Central Valley," Sumner said. "Then they'd move."
