Fog catchers

As in many places in the world, drought in some parts of South America is a big problem.

In Lima, the capital of Peru, rain is very scarce. But thanks to the efforts of biologist Kai Tiedemann, villagers outside of the city center are coaxing water out of the air. The method:
harvesting fog.

I am really impressed to know that fog catchers have been installed in many arid areas where fog is dense. For example, fog catchers in the
Atacama desert (Chile) are converting this dry region to a livable place.
