The present collection of 12 papers ranges from introductory general
reviews to a number of detailed, process oriented, regional and local
studies, related to the distribution of aridic soils and duricrusts in
landscapes of three continents. It is followed by three papers on
modelling and laboratory studies of geomorphic processes significant
in aridic landscapes. It is rounded up by a methodological study of
landform-vegetation relationships and a regional study of
desertification.
