As temperatures recently reached triple digits, farmer Joe Del Bosque inspected the almonds in his parched orchard in California’s agriculture-rich San Joaquin Valley, where a deepening drought threatens one of the state’s most profitable crops.

Del Bosque doesn’t have enough water to properly irrigate his almond orchards, so he’s practicing “deficit irrigation” – providing less water than the trees need. He left a third of his farmland unplanted to save water for the nuts. And he may pull out 100 of his 600 acres of almond trees after the late summer harvest – years earlier than planned.

“We may have to sacrifice one of them at the end of the year if we feel that we don’t have enough water next year,” said Del Bosque, who also grows melons, cherries and asparagus. “That means that our huge investment that we put in these trees is gone.”

A historic drought across the U.S. West is taking a heavy toll on California’s $6 billion almond industry, which produces roughly 80% of the world’s almonds. More growers are expected to abandon their orchards as water becomes scarce and expensive.
