BBC News reports:
The dry, red earth could almost be mistaken for a Martian landscape. It is in fact the Atacama desert in Chile, one of the driest places on Earth.
Average rainfall here is less than 0.1mm (0.004 in) per year and there are many regions which have not seen any precipitation for decades.
But while there is little rain, the clouds here do carry humidity. Coastal fog forms on Chile’s shore and then moves inland in the form of cloud banks. The locals call it “camanchaca”.

Also from the report: ‘The largest expanse of fog catchers is located in Tojquia in Guatemala, where 60 fog catchers trap 4,000 litres of water a day.’
