The first of two volumes, this book contains a collection of selected papers on a wide range of aspects of the natural transport and resorting of sand and soil. Apart from one paper on avalanches and a small number in which sea waves are also an agent, the papers deal exclusively with wind erosion. This second volume reviews the contributions to the literature of aeolian transport which have been published during the last five years, concentrating on soil degradation and desertification. The purpose of the workshop from which these volumes are drawn was to discuss work carried out during these five years but which has not, as yet, been published. The books examine several important field problem classes and a number of new observational techniques. This book of proceedings on geography (geomorphology), agriculture, sedimentology, civil engineering and statistics is intended for research teams, graduate students, senior undergraduates in some subjects, design teams and researchers.
