Desert regions are being impacted by a rapidly-growing and increasingly urban population, which is dependent on scarce surface and groundwater. The importance of water to human and natural systems in deserts makes them very sensitive to those changes in climate that affect the amount, type, timing, and effectiveness of precipitation. Geologic information on the extent and magnitude of climate change on decadal to millennia timescales allows assessment of: (1) the contribution of natural and anthropogenic factors to desertification; (2) the major physical processes of desertification, and (3) the possible nature and effects of future climate changes in order to plan for effective and sustainable mitigation of and adaptation to climate change by the inhabitants of these regions.
