During the last twenty years, mutations within agricultural systems in France and Europe have brought on a spectacular worsening of soil erosion and degradation. This volume, contributed to by scientists from 25 countries, discusses how this risk can be evaluated, and which solutions should be adopted without radically disturbing the socio-economic orientation of major agricultural regions. It is an excellent starting point for the development of new research themes, and will be of great value to soil and environmental scientists, and to all those involved in land irrigation and drainage.

This book deals with the major issues being faced by the coastal population in Asia with emphasis on natural and man-made hazards, climate change impact and pressures caused by mega cities along Asian coasts. The edited book contains chapters authored by experts who are well known in their own fields of specialization relevant to coastal processes. Emphasis has been given to almost all regions of Aisan coast although coverage for south and south eastern regions of Asia is rather strong. Each chapter has been peer reviewed and revised before acceptance. In this book practical suggestions to mitigate problems in sustainable management of coastal regions are also discussed. The book will be useful for students, researchers in physical and social science, policy makers and climate change specialists.

TO THE MODEL EVALUATION 1. MODELLING SOIL EROSION BY WATER l 2 John Boardman and David Favis-Mortlock 1 School of Geography and Environmental Change Unit Mansfield Road University of Oxford Oxford OX1 3TB UK 2 Environmental Change Unit University of Oxford 5 South Parks Road Oxford OX1 3UB UK Introduction This volume is the Proceedings of the NATO Advanced Research Workshop 'Global Change: Modelling Soil Erosion by Water', which was held on II-14th September 1995, at the University of Oxford, UK. The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

The movement of sediment and associated pollutants over thelandscape and into water bodies is of increasing concern withrespect to pollution control, prevention of muddy floods andenvironmental protection. In addition, the loss of soil on site hasimplications for declining agricultural productivity, loss ofbiodiversity and decreased amenity and landscape value. The fate ofsediment and the conservation of soil are important issues for landmanagers and decision-makers. In developing appropriate policiesand solutions, managers and researchers are making greater use oferosion models to characterise the processes of erosion and theirinteraction with the landscape. A study of erosion requires one to think in terms ofmicroseconds to understand the mechanics of impact of a singleraindrop on a soil surface, while landscapes form over periods ofthousands of years. These processes operate on scales ofmillimetres for single raindrops to mega-metres for continents.Erosion modelling thus covers quite a lot of ground. This bookintroduces the conceptual and mathematical frameworks used toformulate models of soil erosion and uses case studies to show howmodels are applied to a variety of purposes at a range of spatialand temporal scales. The aim is to provide land managers and otherswith the tools required to select a model appropriate to the typeand scale of erosion problem, to show what users can expect interms of accuracy of model predictions and to provide anappreciation of both the advantages and limitations of models.Problems covered include those arising from agriculture, theconstruction industry, pollution and climatic change and range inscale from farms to small and large catchments. The book will alsobe useful to students and research scientists as an up-to-datereview of the state-of-art of erosion modelling and, through aknowledge of how models are used in practice, in highlighting thegaps in knowledge that need to be filled in order to develop evenbetter models.

This book reviews the major achievements recently made in soil erosion and sediment redistribution research and management, and identifies future requirements. The book presents work from key players in river basin soil erosion and sediment redistribution from sources to sinks, field to riverbank, from academia to policy and industry. It examines the developments made in three themes - measurement, modelling and management - and covers a variety of scales (in both time and space) and geographical locations.

Deals in detail with the full range of elements appropriate to hillslope research. It develops several key themes in an attempt to bring together the very latest advances in hillslope research. Hydrological, solute, soil, gully and slope stability processes together with processes in tropical, semi arid and periglacial environments are all accorded major sections in the book. Written by internationally renowned experts in the field it brings together recent innovative advances in both modelling and field monitoring. "Hugely valuable publication that not only makes an impressive statement on or contemporary knowledge and methodology but also sets up a well defined platform for future work." Progress in Physical Geography, Vol 21:4 1997

This is the first book to bring together practical examples from around the world to show how geomorphological evidence can help in effective land utilisation and hazard risk assessment. Case studies provide important lessons in risk management, and experts provide summaries of current research. The text also promotes good practice and effective land use, and looks at problems caused by misuse of the environment and potential solutions based on geomorphological evidence.
