Libyan Desert: The world's deserts are under threat, says UNEP. A new report, titled "Global Deserts Outlook," has been released on World Environment Day by the United Nations Environment Programme (UNEP). The report suggests that the world ’ s deserts face dramatic changes as a result of global climate change: high water demands, tourism and salt contamination of irrigated soils. Desert margins and mountainous areas within deserts that have been important for people, wildlife and water supplies for millennia, are under particular threat, say UNEP. 2006 is the United Nations' International Year of Deserts and Desertification. Yet deserts could become the "carbon-free power houses of the 21st century," some experts believe. They argue an area 800 by 800 km of desert, such as the Sahara, could capture the solar energy to generate all the world ’ s electricity needs - and more. "There are many popular and sometimes misplaced views of deserts which this report either confirms or overturns. Far from being barren wastelands, they emerge as biologically, economically and culturally dynamic while being increasingly subject to the impacts and pressures of the modern world," said Shafqat Kakakhel, UNEP ’ s Officer in Charge and Deputy Executive Director. Almost one-quarter of the earth ’ s land surface – some 33.7 million square kilometres – has been defined as "desert" in some sense. These deserts are inhabited by over 500 million people, significantly more than previously thought. In many parts of the world desert cores remain pristine, representing some of the planet ’ s "last remaining areas of total wilderness," stated the UNEP in a news release.
