Reforestation is one of the biggest challenges for humanity, who during the past decades managed to destroy most of the primary forests on Earth and still needs more and more wood - as a fuel, as a raw material for paper and as a building material. The planting of trees is especially difficult in regions where desertification is already taking place.
Pieter Hoff from the Netherlands has designed a simple bucket with two holes, one for planting a seedling and the other for irrigation. Inside the box a micro-climate emerges in which the tree can proliferate, even if the outside climate is too dry and too hot for a tree to grow. This system hardly interferes in the soil, thus permitting the young tree to develop healthy and strong taproots.
Practical experience shows that Pieter's innovation allows trees to grow even in the desert, where they again bind humidity, stabilize the climate and make it possible to sustain new life. A business model for prolific enterprises on land which is thought to be of no value.
