Reforestation in arid lands gets a practical boost with the Waterboxx
Reforesting the planet is a major challenge in arid and semi arid regions where soils have lost the conditions necessary for vegetation. A simple, effective new device is proving its value for planting trees in desert environments. The Groasis Waterboxx continues to show success wherever it is deployed.
According to the makers, these so called magic boxes can support the survival of a large majority of trees planted in harsh environments. They report survival rates around 90 percent in the Sahara during the first year with surprisingly modest water use, about 50 liters per planting cycle.
The initiative began in 2003 when Dutch lily grower Pieter Hoff, recognizing the crisis in the planet’s aquifers, designed this container. It holds everything a tree needs to grow, even in conditions that seem unfavourable.
Waterboxx works by collecting water from nighttime condensation and occasional rainfall to irrigate the plant in small, steady doses. The container also minimizes evaporation and protects the roots from sun, harsh weather, and small animals, enabling the tree to develop healthily.
The system features a circular body that can hold roughly 15 liters of water, with an inverted conical lid that channels any remaining water into a chamber below. In heavy rain, a valve directs excess water to the outside. The center is hollow, allowing two seedlings to grow from the air.
The device connects with the soil through capillary action using a textile rope and a basal cardboard layer, enabling slow, steady hydraulic flow from the water stored in the chamber to the substrate where the seedlings were planted.
The Waterboxx has shown its effectiveness in multiple years and varied locations. In the Sahara desert, trees planted with this system have remained alive at a rate around 90 percent, significantly higher than other methods over the same period.
Successfully tested in Los Monegros
Inside Spain, trials took place in the Monegros desert in Aragon, in Riofrío de Aliste in Zamora, and at the San Isidro ski resort in León. In these trials, tree survival and growth reached between 80 percent and 90 percent of planted trees.
The first prototype was made of plastic, but the design was quickly adapted to use recycled cardboard, the material currently used. Over the last five years, more than 55,000 trees have been planted thanks to the reusable box, supported by about 20,000 Waterboxx units in circulation.
It is noted that the Waterboxx technology is affordable and offers significant cost savings, reported as roughly 90 percent cheaper than drip irrigation and about 90 percent reduction in water consumption compared with traditional methods.
All information about the device is summarized through the official communications from the project developers and independent demonstrations conducted in arid settings. The technology emphasizes low water needs, resilience in extreme heat, and the potential for scalable reforestation in dry regions across North America and beyond.
Environment department inquiries are addressed through official channels and project documentation, which discuss the Waterboxx’s design philosophy and deployment outcomes within environmental restoration initiatives.
