There have been numerous scientific theories on how to transform the deserts of the world into lush farmlands or dense forests. Scientists have developed numerous permaculture projects specifically designed for dry land desert environments. These projects range from”conserving scarce water and nutrients, building up fertile soil, and creating cooling micro-climates to protect tender crops from the desert heat.” Other ideas are”Contour Trenching Technique“, which consists of digging trenches on contour elevation lines in the landscape and trapping precipitation in the trenches” or integrating solar power and desalination technology.
One idea that has been in the news recently is an attempt by the United Arab Emirates to drag an iceberg from the Antarctica (over 5,000 miles) to the coast of Fujairah. It will be used to provide billions of gallons of fresh water and perhaps, as The Emirates’ weather experts hope, the enormous iceberg will change the weather system of this arid country. Some scientists question the possibility of this plan harming the global climate.
