This is what researchers in Chile have concluded after studying the potential of fog harvesting in the desert city of Alto Hospicio in the north of the country.

Average rainfall in the region is less than 0.19in (5mm) per year.

"The city also has a lot of social problems," said lead researcher Dr Virginia Carter Gamberini, from Universidad Mayor. "Poverty, drugs, many slums."

With no access to water supply networks, people in the slums rely on drinking water that is delivered by truck.
