These two volumes contain a collection of selected papers on a wide range of aspects of natural transport and re-sorting of sand and soil. Apart from one paper on avalanche and a small number in which sea waves are also an agent, the papers all deal exclusively with wind erosion. One paper reviews in depth the contributions to the literature of aeolian transport which have been published during the last five years. The purpose of the workshop from which these volumes derive was to discuss work carried out during these five years but not yet published. The collection of papers was reviewed in light of these discussions and can therefore be taken to be a particularly well informed statement about the subject as it stood in mid 1990. Several important field problem classes were examined as were several new observational techniques. This activity, together with widespread concern about soil degradation and desertification in wind transported soils, will probably attract many new workers to the field during the next decade. This summary of its present status will be extremely helpful to them.
