Description of ChallengeTo find a source of water in arid regions
Nylon nets stretched between poles collect water from fog and mist.
In the arid hills around Lima people forced onto dry marginal land are using basic fine nylon nets stretched between wooden poles to collect water. As fog and mists blow through the mesh condensation occurs and the water droplets run down the mesh to be collected in a holding tank. This simple technique enables people to grow crops and helps them transform their lives.
