In Cabazane sub-Saharan Africa a team from the University of South Africa is helping locals to use nets to harvest water from high mountain air.
The project team has hung nets on steel cables at 1,600 metres above sea level to catch tiny droplets of water from the mountain fog near Brooks Nek Pass.  The water droplets are caught in gutters built into the bottom of the nets and then carried by tubes down the side of the mountain to the village. Each square metre of netting provides up to five litres of water per day.
The water is very clean — an especially valuable commodity in a village where the nearest stream is two kilometres away and contaminated by animal use.
