Cardboard donuts
The tree planting project in the Atacama Desert has found a way to reclaim these lands, by planting trees in a clever ‘Cocoon’. The circular biodegradable cardboard structure can hold up to 25 litres of water, which the young tree can live off of as its roots grow. Up to 90% of trees planted in one of these cardboard ‘donuts’ survive, even during droughts. Overall, the Cocoon method uses five times less water than irrigation.
