Collapsing engineering soils are a formidable hazard around the world. These difficult materials also include some of the world's most fertile agricultural soils, fostering dense human populations which are therefore increasingly at risk. Despite an impressive literature on the engineering aspects of collapsing soils, these materials are coming under increasing scrutiny by scientists in other fields. This is most evidently the case with soil scientists, stratigraphers and sedimentologists. Past earth surface conditions have a direct influence on the detailed behaviour of collapsible soils: as a complement, these materials also provide detailed data on changing global climates. The selected papers presented here highlight the common ground between three scientific groups with a vested interest in a better understanding of collapsible soils.

The 11 chapters provide a wide ranging perspective on some of the problems under investigation and several of the systematic approaches currently in use by those concerned with refining the knowledge of the changing environments in the world's drylands during the latter part of the Quaternary. Dealing with a part of the globe that is highly sensitive to small changes of climate, or other stresses such as human impact, this book brings together a set of excellent reviews that will be of great value to students beginning to understand the subject and to paleoenvironmental scientists actively concerned with finding solutions to problems of the region. Additionally, it will be an invaluable archive of important references covering the subject of arid lands palaeoenvironmental research. This volume achieves the aspirations of the International Geological Correlation Programme.
