Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.
Integrated studies on the assessment and improvement of soil and water quality have to deal almost inevitably with issues of scale, since the spatial support of measurements, the model calculations and the presentation of results usually vary. This book contains the selected and edited proceedings of a workshop devoted to issues of scale entitled: `Soil and Water Quality at Different Scales', which was held in 1996 in Wageningen. It is intended for environmental researchers, scientists and MSc and PhD students. Part 1 covers current issues and methodologies with scale related soil and water quality research. Part 2 covers agroecological and hydrological case studies in which scale transforms form an important part of the research chain. Part 3 consists of papers focusing on methodologies and up and downscaling. Part 4 contains review papers based on modellers' and statisticians' considerations as well as the papers and posters presented during the workshop. Part 5 consists of short research notes.
The scope of this book is to show that protected areas may be the regions where early signs of the impact of global change can be observed. These signs are not limited to physical parameters like temperature, precipitation, etc. but could include changes in the biosphere and in social behavior. The book is a collection of papers presented at the meeting `Global Change and Protected Areas' held in L'Aquila, Italy, in September 1998. It is divided into four sections dealing with the physical evidence for climatic and environmental changes, the impact on the biosphere and hydrology and the socio-economic implications. The last section is a case study on the Abruzzo Region which has the peculiarity among the Italian regions of having dedicated a third of its territory to natural parks. Most of the contributions have been prepared for this book and each section is opened by a general review that may also be very useful as a teaching tool. The book will be useful for both the researcher and the student. This rather interdisciplinary subject is totally new, with very few books in print.
The Handbook of Soil Science provides a resource rich in data that gives professional soil scientists, agronomists, engineers, ecologists, biologists, naturalists, and their students a handy reference about the discipline of soil science. This handbook serves professionals seeking specific, factual reference information. Each subsection includes a description of concepts and theories; definitions; approaches; methodologies and procedures; tabular data; figures; and extensive references.
The pedosphere - the thin mantel of soil on the earth's surface - plays a potentially crucial role in climate and climate change . The carbon storage of soils is the second largest in the biosphere, making the dynamics of soil organic carbon an important issue that must be understood if we are to fully comprehend global change. This new book examines the importance of soils and their relationship to global change, specifically to the greenhouse effect. Soils and Global Change presents a state-of-the-art compendium of our present knowledge of soils. This up-to-date information source enables readers to delve into the literature about soils and climate change and examine soils in both natural and managed environments.
