Key Info
  • Living without water: Atacama fog catching nets
  • Duration: 05:03
  • The Atacama desert is on the coast of the Pacific Ocean. Cold sea currents cool the hot desert air and produce huge blankets of fog in the atmosphere and the on shore wind from the sea sweeps the fog inland. Cactus plants thrive by capturing the water in the fog. As the fog hits the cacti, it condenses turning from water vapour into liquid. Animals drink the water droplets, which is a vital source of water for them. Humans have found a way to copy nature and capture this water too. By positioning huge nets on the top of a hill. The nets trap the fog, creating droplets of water, just like the cacti obtaining water. Created especially for Class Clips from the BBC series Human Planet, first broadcast in January 2011.

Ideas for use in class
  • Prior to watching the clips pupils could locate Chile, Santiago and Atacama on a map. Pupils discuss what it would be like to live in a place where it never rains – feedback ideas to the rest of the class. After watching the clip pupils could invent and test out their own ideas for capturing water from the atmosphere. Pupils could investigate where the nearest reservoir to the school is and what happens to the water when it is in the reservoir and how it gets to peoples' homes. More information about the series, images and further clips can be seen on the Human Planet website:
