Discovering the rates at which landscapes change and the causes of these changes is a key current focus in geoscientific, environmental, ecological and archaeological research. The mechanisms are intricate involving many components - a complex of positive and negative feedback mechanisms, and scales varying from the solar system and global tectonics to the activities of microscopic organisms. In this book Andrew Goudie draws together the findings of many disparate disciplines (and of his own research) to present a coherent and structured account of what is known and what remains to be discovered about change and the variable rate of change in the shape and environment of the earth's surface. This is not a research monograph but a research synthesis presented in terms comprehensible to workers in a wide range of disciplines.

Over the past twenty years, geography as an academic discipline has become more and more reflective, asking the key questions 'What are we doing?' 'Why are we doing it?'. These questions have, so far, been more enthusiastically taken up by human geography rather than physical geography. Contemporary Meanings in Physical Geography aims to redress the balance. Written and edited by a distinguished group of physical geographers, Contemporary Meanings in Physical Geography comprises of a collection of international writer's thoughts which reveal personal motivations, and look at tensions in the worlds of meaning in which physical geography is involved. How are the meanings of the physical environment derived? Is the future of physical geography one where the only, or at least the dominant, meanings are framed in the contexts of environmental issues. Covering a diverse and lively selection of topics, the contributors of this book offer guides to the contemporary debates in the philosophy of physical geography, and introduce the reader to its wider cultural significance. This book is an essential companion to anyone studying, or with an interest in, physical geography.

This book provides a detailed coverage of the landforms of Planet Earth and the processes that shaped them. The study of these morphologies, some of which formed during past geological periods under environmental conditions very different from those of today, makes it possible to reconstruct the evolution of relief and to infer environmental changes that have involved geological media, the climate, or human activity. A major advance of Geomorphology in recent decades is the development of techniques that make it possible to quantify morphogenetic processes and rates at which forms change under different environmental conditions. The development of Geochronology, or absolute dating methods, is helping us correct the limitations of relative dating that have prevailed in Geomorphology for many years. The ability to assign numerical ages to both landforms and deposits opens up multiple possibilities for reconstructing the evolution of relief, making correlations, calculating rates, and estimating recurrence periods. A theme of major concern facing people today is the possible warming of the planet due to the release of greenhouse gases into the environment. Investigations conducted by the scientific community show that this temperature increase is at least partially anthropogenic. Given this more-than-probable cause and effect relationship, the most sensible and prudent path is to design and apply mitigation measures to alleviate this heating that can negatively affect both the natural environment and human society. The information that Geomorphology can provide on the recent past (Historical Geomorphology) may be very useful in making predictions on the activity of these potentially dangerous processes in the future and on the possible effects of environmental changes. The aim of this book is to provide a general vision of the multiple aspects of Geomorphology and to provide a methodological foundation to approach the study of various branches of geomorphology. To this end, the book contains a basic bibliography that can be used for future research. In addition, applied aspects of Geomorphology are covered at the end of each chapter to provide knowledge of the activities of geomorphologists in the professional world.

The Impact of Mining on the Landscape

A Study of the Upper Silesian Coal Basin in Poland

This book investigates the Upper Silesian Coal Basin (USCB), one of the oldest and largest mining areas not only in Poland but also in Europe. Using uniform research methods for the whole study area, it also provides a summary of the landscape transformations. Intensive extraction of hard coal, zinc and lead ores, stowing sands and rock resources have caused such extensive transformations of landscape that it can be considered a model anthropogenic relief. The book has three main focuses: 1) Identifying anthropogenic forms of relief related to mining activity and presenting them from a spatial, genetic and age perspective; 2) Determining the changes in the morphometric characteristics of relief and the conditions for matter circulation in open systems (drainage basins) and closed systems (land-locked basins) caused by the extraction of mineral resources; and 3) Estimating the extent of anthropogenic denudation using two different methods based on raw-material output and morphometric analysis. In Poland, no other mining area has undergone such intensive mining activity as the Upper Silesian Coal Basin during the last half century. Its share in the total extraction of mineral resources was as high as 32%. The total extraction of hard coal in the Upper Silesian Coal Basin from the mid-18th century until 2009 was the sixth largest in the world, and the permanent, regional effects of mining anthropopressure on the relief are among the most severe in the world. The anthropogenic denudation rate in the Upper Silesian Coal Basin, as well as the Ruhr Coal Basin (Ruhr District) and the Ostrava-Karvina Coal Basin, ranges from several dozen up to several hundred times higher than the rate of natural denudation, irrespective of the calculation method used. It would take the natural denudation processes tens of thousands of years to remove the same amount of material from the substratum as that removed through human mining activity.

Introduction to Process Geomorphology provides an integrative approach to the process dynamics and the origin of landforms by the contemporary processes involved in their evolution. The author highlights the physical and chemical laws governing the activity of the earth-surface processes in specific environmental stress conditions, puts forward competing hypotheses on the evolution of landforms, and discusses the bases of internal geologic processes for the explanation of the tectogenic features of the earth. Landforms evolve over a long period of cyclic and geologic time, inheriting the imprints of past process rates and/or process domains. The principles and methods of evaluating the signature of environmental change are highlighted in the text by citing suitable studies. The process-form relationships provide the building blocks also for the optimum utilization of the land resources of the earth, and quantitative assessment of the stability of geomorphic systems and the quality of environment. The approach in this part of the text enables readers to gain an in-depth understanding of the application of the principles of geomorphology to the evaluation, planning, and management of the earth’s resources for sustainable development. This book discusses process dynamics in quantitative terms and reviews theories on the evolution of landforms that flow from theoretical and empirical data. It offers examples and case studies that enable students to comprehend the related components of process-landform relationships. The review and synthesis of information found in each chapter provides a better understanding of the complexity of still inadequately understood process activities and the manner of landform evolution.

About one-third of the Earth’s land surface experiences a desert climate, and this area supports approximately 15% of the planet’s population. This percentage continues to grow, and with this growth comes the need to acquire and apply an understanding of desert geomorphology. Such an understanding is vital in managing scarce and fragile resources and in mitigating natural hazards. This authoritative reference book is comprehensive in its coverage of the geomorphology of desert environments, and is arranged thematically. It begins with an overview of global deserts, proceeds through treatments of weathering, hillslopes, rivers, piedmonts, lake basins, and aeolian surfaces, and concludes with a discussion of the role of climatic change. Written by a team of international authors, all of whom are active in the field, the chapters cover the spectrum of desert geomorphology.

The papers in this volume revisit one of the concerns which dominated environmental archaeology through the 1960s and 1970s, namely the timing, nature and extent of human impact on the environment. The thirteen contributions reflect the diversity of approaches and ideas today and show how our understanding of the place of people in ecosystems is now more subtle. There are papers on palynological evidence from the Strymon Delta in Macedonia; prehistoric copper mining at Mount Gabriel, Ireland; fungal spores as anthropogenic indicators on Shetland; prehistoric human impact on the prehistoric environments of Orkney, North York Moors and the Mid-Devon landscape; mites as indicators of human impact in the Netherlands; the disappearance of Elmid Riffle Beetles' from lowland river systems in Britain; and case studies from further afield: palaeoenvironmental reconstruction in the Central Mexican Highlands; food plant availability in the Murchison Basin, Western Australia, prior to European arrival and Paleoindian expansion into South America.

Human activities have had a huge impact on the environment and landscape, through industrialisation and land-use change, leading to climate change, deforestation, desertification, land degradation, and air and water pollution. These impacts are strongly linked to the occurrence of geomorphological hazards, such as floods, landslides, snow avalanches, soil erosion, and others. Geomorphological work includes not only the understanding but the mapping and modelling of Earth's surface processes, many of which directly affect human societies. In addition, geomorphologists are becoming increasingly involved with the dimensions of societal problem solving, through vulnerability analysis, hazard and risk assessment and management. The work of geomorphologists is therefore of prime importance for disaster prevention. An international team of geomorphologists have contributed their expertise to this volume, making this a scientifically rigorous work for a wide audience of geomorphologists and other Earth scientists, including those involved in environmental science, hazard and risk assessment, management and policy.

Mountains represent one of the most inspiring and attractive natural features on the surface of the earth. Visually, they dominate the landscape. However, the increasing realization of the fragility of mountain areas because of changes in land use, management and climate, combined with an understanding of their importance for water and other natural resources, has resulted in a growing interest in mountain environments in recent years. Hence, Mountain Geomorphology represents a timely and unique contribution to the literature. Written by a team of international experts, this book is divided into three sections, which consider historical, functional and applied mountain geomorphology from both global and local perspectives. Historical mountain geomorphology focuses on the evolution of landforms. Functional mountain geomorphology emphasises the interaction between processes and landforms, while applied mountain geomorphology concerns the interrelationships between geomorphological processes and society. Mountain Geomorphology is a valuable source of information for students studying mountain geomorphology, and also for academics and research scientists interested in mountain environments.
