Description :
In many of the Earth's arid and semiarid lands, saline lakes, playas, and similar landforms are disturbed as a result of human activity. The dessication of playa systems is accomplished by abstraction of water and/or removal of vegetation from terminal lake basins, and has resulted in the eolian transport of sand. An extensive review of the literature documents many examples of such phenomena in numerous stations. The reactivation of eolian processes from closed basins produces air pollution in the form of fugitive dust, and has environmental and economic impacts on human activities. Restoration has been accomplished on some playas.
