The WaterBoxx needs just 3 inches of rainfall per year to deliver a slow and steady supply of water to plants or trees
From the land of dams and canals comes a new device billed as the savior of agriculture and reforestation in drought-plagued areas.
The “Waterboxx” is the brainchild of Dutch businessman Pieter Hoff, who sold his lily-growing operation in 2003 to focus on water. Then he started tinkering with a polypropylene box, about the size of a laundry basket. It has a fluted lid and a wick extending from the bottom. The plant sits in a cylindrical opening in the center that goes all the way through the box.
The mechanism is almost suspiciously simple. The box collects rainwater and condensation and funnels it to the plant. In spring 2009, Hoff partnered with Eduard Zanen, co-founder of the stroller company Bugaboo International, to finance experiments with the device that are now under way in Kenya, Morocco, Spain and the United States. Eight hundred of the boxes have been installed in Joshua Tree National Park, where they are nourishing native mesquite and saltbush plants.
Hoff, an impassioned climate evangelist, published a book in 2008 titled “CO2: A Gift From Heaven,” which argues that policymakers should leave the climate debate aside and focus on planting trees. Planting 5 billion acres of trees — about 2.5 times the surface area of Canada — would be enough to offset annual emissions of 10 billion metric tons of CO2, he calculates.
For Hoff, the box is the solution. It collects any amount of water — from inches of rainfall to minute droplets of condensation — and delivers it slowly and steadily. Just 3 inches of rainfall per year is enough to keep the box’s water supply replenished. It can also be screwed into the ground, both to prevent theft and to secure it to sloping or rocky land.
“We can use the box to reforest California, and we can use it to restore our water tables to safer levels again,” he said.
Margrit Mondavi, the widow of Napa Valley winemaker Robert Mondavi, christened two of the devices at her vineyard last week with a bottle of 1990 Reserve Cabernet Sauvignon. She called it an important development “because water is becoming more precious all the time.”
Matt Ashby, director of vineyards for Mondavi, is conducting an experiment with 500 Waterboxxes around new grapevines. He’ll compare their growth in the fall to a control group of 10,000 vines that are receiving conventional drip irrigation.
“I’m not sure why no one’s done it before,” he wondered, adding: “I’m convinced it’s going to work.”
