Chile’s Atacama Desert is one of the driest places in the world. Some areas only see rainfall a few times in a century, while others have never recorded rainfall at all. In many rural communities there, local governments have to truck in water from other parts of the country or extract it from deep underground wells. But in harder-to-reach settlements, these solutions still aren’t cost-effective or reliable. To address the problem, residents and researchers have looked for more innovative methods of getting water out of the environment. Some have begun using the fog that often blankets northern Chile. Off the Pacific coast, cold air currents cool into low cloud cover that blows inland, getting stopped by coastal mountains and settling at ground level. With the right approach, groups have found ways to “capture,” or “harvest,” the fog, turning it into useable freshwater. “In a very simple way, we have to understand that clouds are made up of water droplets,” Camilo del Río, director of the Catholic University’s Atacama Desert Center in Chile, told Mongabay. “They’re already formed, they’re already condensed. So whenever a cloud is transported by wind and comes into contact with the Earth’s surface, what is touching the surface is thousands and thousands of liters [of water].” Local groups have found ways to harvest enough fog to supplement drinking water and bolster agricultural projects. But many challenges with the strategy still remain. Researchers want to harvest the fog more efficiently and at scale, one day convincing local officials…This article was originally published on Mongabay
