The Seawater Greenhouse transforms seawater into fresh water, salt, nutrients as well as cool, humid air, enabling crops to be grown in hot, arid regions.
The world is not short of water; it is just in the wrong places and too salty. Converting seawater to fresh water, in the right places, offers great potential for agriculture. Seawater Greenhouse uses seawater to cool, sterilize and humidify the air going into their greenhouses. Cooler and more humid conditions in the Seawater Greenhouses reduce the water demand of plants by 4 to 8 times compared to plants grown outside, according to the company. In addition to the water savings, both the yield and quality of crops are higher.
Why you should care
Agriculture uses 60 to 80% of the planet’s scarce fresh water resources. With an increasing global demand for fresh water, agriculture is under pressure to become more water-efficient, as it is one of the most water-dependent sectors. By harnessing abundant seawater, Seawater Greenhouse is helping to reduce the pressure on fresh water resources and bring sustainable agriculture to arid, drought-prone areas.
