Incredible Sahara Forest Project Moves From Concept To Reality With Major Development Deal. Images via Exploration Architecture - original visualisation of Sahara Forest Project There's great news for sustainable design innovation this week as the Sahara Forest Project gets backing from a development deal between Norway and Jordan. We wrote about this incredible proposal to create carbon neutral energy, fresh water, food and fuel crops through symbiotic technologies back in 2008.
Now, after years of hard work and persistence from the collaborative Sahara Forest Project team, this large scale concept is going to become a big reality. Here is the new vision... International Collaboration between Norway and JordanAfter joining forces with the Norwegian environmental group the Bellona Foundation in 2009 The Sahara Forest Project team, including biomimicry architect Michael Pawlyn, Seawater Greenhouse designer Charlie Paton and building services engineer Bill Watts, presented their proposal at COP15.
With financial backing from Norway it has been agreed that ASEZA will: Seawater Greenhouse. A seawater greenhouse is a greenhouse structure that enables the growth of crops in arid regions, using seawater and solar energy. The technique involves pumping seawater (or allowing it to gravitate if below sea level) to an arid location and then subjecting it to two processes: first, it is used to humidify and cool the air, and second, it is evaporated by solar heating and distilled to produce fresh water. Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants. The technology was introduced by British inventor Charlie Paton in the early 1990s and is being developed by his UK company Seawater Greenhouse Ltd.
The more concentrated salt water may either be further evaporated for the production of salt and other elements, or discharged back to the sea. The seawater greenhouse is a response to the global water crisis and peak water.

Al Ain: Sea water is being used in farming research to water crops that tolerate, and even need salt to thrive. If successful, farms along the coastline whose fresh water wells dried up long ago could pick up again giving depleted aquifers time to recharge.
Salt-tolerant grass, called halophytes, produced for golf courses or forage for cattle and camels, are the focus of modern farming techniques being developed by the Faculty of Food and Agriculture at UAE University in Al Ain to save water. Environmental economists have highlighted that while domestic agriculture is a serious drain on freshwater water tables in the UAE, arable land is limited and future farming expansion has no potential. According to the Gulf Research Centre agriculture in the UAE accounts for only 2.8 per cent of gross domestic product (GDP), but consumes about 80 per cent of underground water reserves. In Abu Dhabi, the government recently launched a scheme to pump desalinated seawater underground. Seawater Farming | Mission 2014: Feeding the World. Problem Seawater farming addresses the severe lack of freshwater and undesirable soil conditions for agricultural activities in coastal regions.
Saltwater, instead of freshwater, can be used to directly support a wide range of sustainable agricultural activities and enrich the soils in the coastal regions. Freshwater, which is defined by having much lower salts and ions concentration than seawater and brackish water, only composes about 2.75% out of all water on Earth, and 74.5% of all freshwater are contained in the glaciers, which are not readily available for consumption.
Freshwater is not distributed evenly, and in many regions around the world, such as the Sub-Sahara region and the Sub-Indian continent, water is seriously scarce or heavily contaminated. While many projects have demonstrated the viability of seawater farming in specific locations, little researches have been done to study seawater farming in a wide variety of conditions.
