Rural communities in arid regions have harvested tiny droplets of fog for years as a source of fresh drinking water. Now, researchers say that fog water can be a practical supplement to stave off water stress for larger desert cities.
A yearlong assessment of the potential volume of harvested fog water near a city in northern Chile’s Atacama Desert found that it’s possible to collect as much as 5 liters per square meter each day, scientists report Feb. 20 in Frontiers in Environmental Science.
