The world is running short of fresh water. With agriculture accounting for some 70% of all water used, the shortage has an impact on food production. The provision of clean water is a pre-condition to life, health and economic development and the lack of water in many parts of the world is the root cause of much suffering and poverty.  Present methods of supply in arid regions include: over-abstraction from ground reserves, diverting water from other regions and energy-intensive desalination. None of these methods is sustainable in the long term and inequitable distribution leads to conflict.  To make matters worse, climate change is tending to make dry areas drier and wet areas wetter.  Since the 1980’s, rainfall has increased in several large regions of the world, including eastern North and South America and northern Europe, while drying has been observed in the Sahel, the Mediterranean, southern Africa, Australia and parts of Asia.  In regions of India, the water table is now 150m below the surface and falling by 6m a year.

The International Water Management Institute recently estimated that in India, about 250 cubic kilometers of water are abstracted for irrigation each year. That is at least 100 cubic kilometers more than the rains put back. It feeds India, but with every passing year, the aquifers get emptier.

Fortunately, the world is not short of water, it is just in the wrong place.  Using modelling software to simulate the growing environment, Seawater Greenhouses Ltd will optimize a design to maximize the cooling and humidifying effects of converting seawater to fresh water in the right quantities to offer the potential to solve many of the world’s problems created by water and food shortages. . The company then custom-designs the specific greenhouse to fit the economic and climate conditions of a particular region. The company’s latest project, to a completely new design, is in Somaliland.
