    [size=14pt]Could Boxes of Water Help Reforest the World?[/size]

    The WaterBoxx needs just 3 inches of rainfall per year to deliver a slow and steady
    supply of water to plants or trees

    [size=8pt]PLANT PRESERVER: The Waterboxx, shown here with inventor Pieter Hoff,
    is a low cost device that can help plants to survive in drought-ridden areas.[/size]

    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."

    First, add water
    To start, the farmer fills the box partway with 2 gallons of water. Any condensation or rain is theoretically
    enough to keep the box filled and supplying enough water to the plant via the wick. The device is stoppered
    with a siphon to prevent evaporation. The box has to be oriented facing a certain way, so the oblong
    opening in the center points east-west and shades the plant from the sun during the hottest part of the day.

    The box is removed after the plant sends its roots deep enough to access groundwater.
    It can then be used over and over again.

    Hoff said he has spent about $7 million on the project thus far, with about $500,000 coming from the
    Dutch government. He has been through more than 10 prototypes, and is also working on building one
    out of biodegradable material, for one-time use in remote areas like the Sierra Nevada.

    Right now, Hoff sells the boxes for $275 for 10, manufactured in his native Holland, but he envisions
    local production wherever the box is sold. "I think it's a disaster that the only people who know how to
    weave clothing are in China," he said. Gardening and home-improvement stores could sell them for
    about $15, he said.

    Speaking about African population disaster this thread, the waterboxx device could be a solution.
    Grow more trees, make land arable, and sustain a bigger population.
