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.

During geologic spans of time, Earth's shifting tectonic plates, atmosphere, freezing water, thawing ice, flowing rivers, and evolving life have shaped Earth's surface features. The resulting hills, mountains, valleys, and plains shelter ecosystems that interact with all life and provide a record of Earth surface processes that extend back through Earth's history. Despite rapidly growing scientific knowledge of Earth surface interactions, and the increasing availability of new monitoring technologies, there is still little understanding of how these processes generate and degrade landscapes. Landscapes on the Edge identifies nine grand challenges in this emerging field of study and proposes four high-priority research initiatives. The book poses questions about how our planet's past can tell us about its future, how landscapes record climate and tectonics, and how Earth surface science can contribute to developing a sustainable living surface for future generations.

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.

From the oceans to continental heartlands, human activities have altered the physical characteristics of Earth's surface. With Earth's population projected to peak at 8 to 12 billion people by 2050 and the additional stress of climate change, it is more important than ever to understand how and where these changes are happening. Innovation in the geographical sciences has the potential to advance knowledge of place-based environmental change, sustainability, and the impacts of a rapidly changing economy and society. Understanding the Changing Planet outlines eleven strategic directions to focus research and leverage new technologies to harness the potential that the geographical sciences offer.

The new fourth edition of Fundamentals of Geomorphology continues to provide a comprehensive introduction to the subject by discussing the latest developments in the field, as well as covering the basics of Earth surface forms and processes. The revised edition has an improved logically cohesive structure, added recent material on Quaternary environments and landscapes, landscape evolution and tectonics, as well as updated information in fast-changing areas such as the application of dating techniques, digital terrain modelling, historical contingency, preglacial landforms, neocatastrophism, and biogeomorphology. The book begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: Endogenic processes: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints. Exogenic processes: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and long-term geomorphology, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. Featuring over 400 illustrations, diagrams, and tables, Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, and providing guides to further reading, chapter summaries, and an extensive glossary of key terms, this is an indispensable undergraduate level textbook for students of physical geography.

Anthropogenic geomorphology studies society’s impact on the geographical environment, and especially on the Earth’s surface. This volume provides guidance to students discussing the basic topics of anthropogenic geomorphology. The chapters cover both its system, and its connections with other sciences, as well as the way the subject can contribute to tackling today’s practical problems. The book represents all fields of geomorphology, giving an introduction to the diversity of the discipline through examples taken from a range of contexts and periods, and focusing on examples from Europe. It is no accident that anthropogenic geomorphology has been gaining ground within geomorphology itself. Its results advance not only the theoretical development of the science but can be applied directly to social and economic issues. Worldwide, anthropogenic geomorphology is an integral and expanding part of earth sciences curricula in higher education, making this a timely and relevant text.

Geomorphology has now reached a certain level where the methodology, scientific content and results being published in the field make it worthy of being considered as a major environmental research area. In preparing Environmental Geomorphology, the author has given priority to methodology and illustrative case-histories. Schemes and classifications that would be ill-suited for a naturalistic, empirical and non-systematic discipline like geomorphology have been avoided. The concepts outlined in the text are based on a subdivision of geomorphological resources and hazards (as well as their links with man) together with the consequent risk and impact problems. Each investigation, study or intervention concerning the environment, cannot ignore either the human context in which it occurs or man's history and prospects. It is necessary to have the right dialogue and relationship with the other disciplines making up this system so as to apply the most suitable methodologies and offer the most valid solutions. For some subjects covered in the book, specialists concerned with a particular section of environmental geomorphology were consulted. The text of each chapter is accompanied by several illustrative schemes, figures and photographs, derived from real research and professional experiences. The volume is addressed both to university students studying topics of geomorphology as part of their syllabus, and to researchers and consultants (geologists, geographers, engineers, naturalists, etc.) working in the field.

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.
