New Delhi: The world's only coastal desert is in Namibia, Africa.
It consists of dune fields winding over its 3 million hectares.
The most widespread and dominant type of desert sand dune are linear dunes, with crescent shaped dunes common along the coast and clusters of star dunes, such as the towering horseshoe of dunes at Sossusvlei, found in the eastern reaches of the sand sea.
