The river water in the farming region of Bujama in Lima, Peru, is so heavily polluted with metals such as lead, arsenic and cadmium, that growing vegetables in the area become heavily contaminated.
Engineering students at Lima’s University of Engineering and Technology (UTEC) have dubbed their invention the “air orchard”
This ingenious device is fitted with 10 de-humidifiers that filter water from the air into a drip irrigation system connected to an urban farm on the ground below.
