The Catchers in the Fog

Rain rarely falls on these dry hills. The annual precipitation in Lima is about half an inch (1.5 centimeters), and the city gets its water from far-off Andean lakes.

But every winter, from June to November, dense fog sweeps in from the Pacific Ocean.

With a few thousand dollars and some volunteer labor, a village can set up fog-collecting nets that gather hundreds of gallons of water a day—without a single drop of rain falling.
