Drought is transforming California, with broad consequences for our food supply
In America’s fruit and nut basket, water is now the most precious crop of all. It explains why, amid a historic drought parching much of the American West, a grower of premium sushi rice has concluded that it makes better business sense to sell the water he would have used to grow rice than to actually grow rice. Or why a melon farmer has left a third of his fields fallow. Or why a large landholder farther south is thinking of planting a solar array on his fields rather than the thirsty almonds that delivered steady profit for years.
These are among the signs of a huge transformation up and down California’s Central Valley, the country’s most lucrative agricultural belt, as it confronts both an exceptional drought and the consequences of years of pumping far too much water out of its aquifers. Across the state, reservoir levels are dropping and electric grids are at risk if hydroelectric dams don’t get enough water to produce power. Climate change is supercharging the scarcity. Rising temperatures dry out the soil, which in turn can worsen heat waves.
