THE ATACAMA DESERT is located in northern Chile.

CLIMATE ‘It does not rain much in the Atacama desert,’ says The Economist. ‘A 1,000km strip of land running along the Chilean coast, it is Earth’s driest desert outside its poles. Average annual rainfall in certain parts can be as low as a millimetre or two a year, and some Atacaman weather stations have never seen a drop of water’.1‘Waiting for Rain’, The Economist March 3rd 2018, p68.
