A drought-hit California town finds itself sinking into the ground

To irrigate its vast fields and help feed America, farm operators began in the last century to pump water from underground sources, so much so that the ground has begun to sink—imagine a series of giant straws sucking up groundwater faster than rain can replenish it, as hydrologist Anne Senter explained it to AFP.

Strangely, signs of this subsidence are nearly invisible to the human eye. There are no cracks in the walls of the typical American shops in the town's center, nor crevices opening up in the streets or fields: to measure subsidence, Californian authorities had to turn to NASA, which used satellites to analyze the geological change.

And yet, over the past 100 years, Corcoran has sunken "the equivalent of a two-story house," Jeanine Jones, a manager with the California Department of Water Resources, told AFP.

The phenomenon "can be a threat to infrastructure, groundwater wells, levees, aqueducts," she said.

Few locals have spoken out against the problem—not surprising, since most of them work for the same big agribusinesses pumping up groundwater.

"They are afraid that if they speak against them, they might lose their job," said Atilano. He spent years working for one of the country's biggest cotton producers, J.G. Boswell, whose name is seen on thousands of cloth bags stuffed with cotton that are seen stacked around town.
