Using the principles of biomimicry, the Groasis Waterboxx enables plants to establish themselves and survive even in the most arid regions of the world, just the way nature does it. Pieter Hoff, founder of AquaPro and inventor of the product, hopes to use the new device to combat hunger, desertification, and climate change.
Hoff has developed a round, 20-inch-wide container crafted from polypropylene that is placed over a two small seedlings. The container is a resevoir for enough water for a full year of micro-drip irrigation. The chamber, which is designed to prevent evaportation, collects rainwater but also maximizes the formation of dew droplets. In some climates dew may be the only frequent source of plant moisture. The Waterboxx design effectively capatures and tranfers condensation into the water reservoir. A wick goes into the ground beneath the box, slowly dripping 50 ml of water to the plant’s root system everyday.
As the plant grows, its roots reach deeper and deeper in the ground, eventually finding their own water source. If all goes well the box can be removed after one year.
Popular Science selected The Groasis Waterboxx as as one of the top 10 inventions of 2010.
These three videos explain how it works very well:

The Winner of the 2010 Buckminster Fuler Challenge is Operation Hope, submitted by Allan Savory on Behlalf of the Africa Center for Holistic Management
"This project demonstrates how to reverse desertification of the world’s savannas and grasslands, thereby contributing enormously to mitigating climate change, biomass burning, drought, flood, drying of rivers and underground waters, disappearing wildlife, massive poverty, social breakdown, violence and genocide."

SLIDE SHOW: Project team in the field in AfricaCritical Need Being Addressed
"Viewed holistically biodiversity loss/desertification/climate change are one issue not three. Without reversing desertification, climate change cannot be adequately addressed. This project has demonstrated that livestock can reverse desertification, even during droughts, over the largest areas of the Earth’s land – the grasslands and savannas."Description of Initiative
"Our work established a previously unsuspected cause of desertification – that humans of all ages and cultures make decisions using the same core decision framework. Flaws in this universal framework made world-wide desertification inevitable. Modifications, explained in "Holistic Management" A New Framework for Decision Making" Savory & Butterfield Second Edition 1999, Island Press, make reversing desertification possible."
"This work, begun in the early 60s gave erratic results. Since 1984 when the decision-making piece of the puzzle fell into place, as long as the process is followed results in restored grasslands have been consistent and can be guaranteed."
"In this particular project ACHM has demonstrated on 6500 acres of grasslands in Zimbabwe the process of reversing desertification. Livestock have increased 400% using holistic planned grazing and we now enjoy open water, water lilies and fish a kilometer above where water has been known before in the dry season. The livestock are integrated with Africa’s big game avoiding competition and wildlife are on the increase. Currently, we can barely keep pace with grass growth even in dry years. This is greatly influencing scientists, NGO’s and pastoralists from all over Africa." READ MORE »

This posting provides some more info on some of the technology used by Dr. Thomas J. Goreau, namely the Biorock® Process. I wonder if he used geodesic and tensegrity structures as the frame for the Biorock(R) if there would be an advantage?
Biorock Technology, or mineral accretion technology is a method that applies safe, low voltage electrical currents through seawater, causing dissolved minerals to crystallize on structures, growing into a white limestone similar to that which naturally makes up coral reefs and tropical white sand beaches. This material has a strength similar to concrete. It can be used to make robust artificial reefs on which corals grow at very rapid rates. The change in the environment produced by electrical currents accelerates formation and growth of both chemical limestone rock and the skeletons of corals and other shell-bearing organisms.
The Biorock Process is owned by Biorock, Inc. and is licensed to GCRA for applicable projects.
Biorock methods speed up coral growth in damaged areas and restore authentic coral reef habitat and species. Biorock structures become rapidly colonized by a full range of coral reef organisms, including fish, crabs, clams, octopus, lobster, sea urchins. Species typically found in healthy reef environments are given an electrical advantage over the weedy organisms which often overgrow them in reefs stressed by humans. The advantages corals gain from mineral accretion are cancelled if they no longer receive current, at which point weeds will overgrow the corals. If the current is maintained, coral reefs can often be restored even in areas where water quality would prevent their recovery by any other method.
Biorock projects can be powered by a wide range of electrical sources including renewable energy like windmills, photovoltaic solar panels and tidal current generators. This enables their construction in areas where conventional electric power is unavailable.

Dr. Thomas J. Goreau and his team received an award in the IDEAS Competition at MIT, Cambridge, MA for their tidal energy device which is used to re-establish dead coral reefs. The coral communities grow very quickly and can survive at higher water temperatures.
