The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text.

"This new edition strengthens the book''s position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm''s reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

Peace operations remain a principal tool for managing armed conflict and protecting civilians. The fully revised, expanded and updated third edition of Understanding Peacekeeping provides a comprehensive and up-to-date introduction to the theory, history, and politics of peace operations.

Drawing on a dataset of nearly two hundred historical and contemporary missions, this book evaluates the changing characteristics of the contemporary international environment in which peace operations are deployed, the strategic purposes peace operations are intended to achieve, and the major challenges facing today’s peacekeepers. All the chapters have been revised and updated, and five new chapters have been added – on stabilization, organized crime, exit strategies, force generation, and the use of force.

Part 1 summarizes the central concepts and issues related to peace operations. Part 2 charts the historical development of peacekeeping, from 1945 through to 2020. Part 3 analyses the strategic purposes that United Nations and other peace operations are intended to achieve – namely, prevention, observation, assistance, enforcement, stabilization, and administration. Part 4 looks forward and examines the central challenges facing today’s peacekeepers: force generation, the regionalization and privatization of peace operations, the use of force, civilian protection, gender issues, policing and organized crime, and exit strategies.

Security Studies: An Introduction, 4th edition, is the most comprehensive textbook available on the subject, providing students with in-depth coverage of traditional and critical approaches and an essential grounding in the debates, frameworks, and issues of the contemporary security agenda.

This new edition has been completely revised and updated, to cover major developments such as COVID-19, the rise of populism, climate change, China and Russia’s place in the world, and the Trump administration. It also includes new chapters on great power rivalry, emerging technologies, and economic threats.

Divided into four parts, the text provides students with a detailed, accessible overview of the major theoretical approaches, key themes, and most significant issues within security studies.

Collecting these related strands into a single textbook creates a valuable teaching tool and a comprehensive, accessible learning resource for undergraduates and MA students.

Modeling Atmospheric and Oceanic Flows: Insights from Laboratory Experiments and Numerical Simulations provides a broad overview of recent progress in using laboratory experiments and numerical simulations to model atmospheric and oceanic fluid motions. This volume not only surveys novel research topics in laboratory experimentation, but also highlights recent developments in the corresponding computational simulations. As computing power grows exponentially and better numerical codes are developed, the interplay between numerical simulations and laboratory experiments is gaining paramount importance within the scientific community. The lessons learnt from the laboratory–model comparisons in this volume will act as a source of inspiration for the next generation of experiments and simulations. Volume highlights include:

Modeling Atmospheric and Oceanic Flows will be a valuable resource for graduate students, researchers, and professionals in the fields of geophysics, atmospheric sciences, oceanography, climate science, hydrology, and experimental geosciences.

The ongoing crisis in Darfur, Sudan has stimulated a huge amount of political and academic interest across the world. The crisis has been both reflective and constitutive of key areas of contestation and change within contemporary international society.

This book examines the crisis in Darfur as a case study of some of the wider debates currently taking place within International Relations theory. Using the conceptual framework developed by English School theorists, specifically their concept of international society and the related idea of "good international citizenship", this book examines a wide range of issues: foreign policy analysis, theories of norm diffusion, international organizations, peace operations, international criminal justice and war law, the causes and nature of contemporary warfare, and the international relations of Africa.

Making an important contribution to the debate about the meaning and limits of international society, this book will be of interest to students and scholars international relations theory, international security, foreign policy, international organizations, human rights, African politics, genocide studies and international law.
