"At a time when the world's population continues to grow, arable land is under threat from deforestation, poor management and global warming. All these factors point to vertical farming being an idea whose time may finally have arrived - and what better place to put it to the test than Dubai. That's the thinking of Italian architectural firm Studiomobile, who have been working on housing and infrastructure projects in the United Arab Emirates where a lack of fresh water and a high soil value make such a concept feasible.

The vertical farm features a soaring spire with pod-like ‘sky-gardens' branching off to give it an organic feel in keeping with designers aims to create a clean, green, sustainable source of food for a more self-sufficient Dubai. The concept makes use of the Seawater Greenhouse process, which uses seawater to cool and humidify the air that ventilates the greenhouse and sunlight to distill fresh water from seawater to enable the year round cultivation of high value crops that would otherwise be difficult or impossible to grow in hot, arid regions such as Dubai. This is in stark contrast to costly and energy intensive desalination plants that rely on boiling and pumping to produce fresh water."
