Notes
Using brackish or even sea water to irrigate plants is now possible thanks to a solar distillation greenhouse. The water to be distilled is circulated in the upper levels of the greenhouse and condenses on the inner surfaces of the roof which it then runs down to be collected below. This more or less pure water is either used directly or stored. Thanks to a special glass that separates the roof from the plants, most of the sunlight is used to produce the heat needed for distillation. This also means a reduction in plant evapotranspiration and thus less water loss. This greenhouse is designed for areas where water is scarce or of poor quality. It can thus increase the production of fresh vegetables in regions where freshwater supply is limited as well as act as a tree nursery in isolated reforestation programmes.
