Sand Dune Encroachment and Desertification Processes of the Rigboland Sand Sea, Central Iran

Abstract Early studies on sand dune movement and desertification in Iran have not always been convincingly demonstrated because of problems with the field-based measurements. In some areas where various land uses have been engulfed by aeolian sand dunes, desertification is clear, but in other less s...
