Cover Story: Egypt is the land of dunes. Investigations of satellite images and field measurements show that nearly all dune forms can be observed. Longitudinal dunes and barchans prevail. The study reviews the state of knowledge around distribution, sizes, dynamics, and ages of all six sand seas (large areas with more than 50% dune coverage) and ten dune fields in Egypt. Regarding the sparse chronological data to date, for a reasonable estimation of future sand mobility in the course of global climate change, further data are essential. Finally, further studies concerning sand mobility, local wind systems, and land use are needed. View this paper
