Global environmental change (GEC) represents an immediate and unprecedented threat to the food security of hundreds of millions of people, especially those who depend on small-scale agriculture for their livelihoods. As this book shows, at the same time, agriculture and related activities also contribute to GEC by, for example, intensifying greenhouse gas emissions and altering the land surface. Responses aimed at adapting to GEC may have negative consequences for food security, just as measures taken to increase food security may exacerbate GEC. The authors show that this complex and dynamic relationship between GEC and food security is also influenced by additional factors; food systems are heavily influenced by socioeconomic conditions, which in turn are affected by multiple processes such as macro-level economic policies, political conflicts and other important drivers. The book provides a major, accessible synthesis of the current state of knowledge and thinking on the relationships between GEC and food security. Most other books addressing the subject concentrate on the links between climate change and agricultural production, and do not extend to an analysis of the wider food system which underpins food security; this book addresses the broader issues, based on a novel food system concept and stressing the need for actions at a regional, rather than just an international or local, level. It reviews new thinking which has emerged over the last decade, analyses research methods for stakeholder engagement and for undertaking studies at the regional level, and looks forward by reviewing a number of emerging 'hot topics' in the food security-GEC debate which help set new agendas for the research community at large.

Global environmental change often seems to be the most carefully examined issue of our time. Yet understanding the human sideâ€"human causes of and responses to environmental changeâ€"has not yet received sustained attention. Global Environmental Change offers a strategy for combining the efforts of natural and social scientists to better understand how our actions influence global change and how global change influences us. The volume is accessible to the nonscientist and provides a wide range of examples and case studies. It explores how the attitudes and actions of individuals, governments, and organizations intertwine to leave their mark on the health of the planet. The book focuses on establishing a framework for this new field of study, identifying problems that must be overcome if we are to deepen our understanding of the human dimensions of global change, presenting conclusions and recommendations.

The year 2007 could perhaps accurately be described as the year when climate change finally received the attention that this challenge deserves globally. Much of the information and knowledge that was created in this field during the year was the result of the findings of the Fourth - sessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC), which were disseminated on a large scale and reported extensively by the media. This was the result not only of a heightened interest on the part of the public on various aspects of climate change, but also because the IPCC itself proactively attempted to spread the findings of its AR4 to the public at large. The interest generated on the scientific realities of climate change was further enhanced by the award of the Nobel Peace Prize to the IPCC and former Vice President of the US, Al Gore. By taking this decision in favour of a leader who has done a great deal to create awareness on c- mate change, and a body that assesses all scientific aspects of climate change and disseminates the result of its findings, the Norwegian Nobel Committee has clearly drawn the link between climate change and peace in the world.

The handbook Global Environmental Change is intended to serve as a reliable and comprehensive resource to attend the needs of researchers, teachers, students, and professionals working in science and policy aspects relevant to environment and sustainability. Entries in the handbook are arranged by major section, and are extensively cross-referenced to allow users to find related titles in a user-friendly way. The handbook is available as a printed volume and as an on-line reference work.

How can we understand and rise to the environmental challenges of global change? One clear answer is to understand the science of global change, not solely in terms of the processes that control changes in climate and the composition of the atmosphere, but in how ecosystems and human society interact with these changes. In the last two decades of the twentieth century, a number of such research effortsâ€"supported by computer and satellite technologyâ€"have been launched. Yet many opportunities for integration remain unexploited, and many fundamental questions remain about the earth's capacity to support a growing human population. This volume encourages a renewed commitment to understanding global change and sets a direction for research in the decade ahead. Through case studies the book explores what can be learned from the lessons of the past 20 years and what are the outstanding scientific questions. Highlights include: Research imperatives and strategies for investigators in the areas of atmospheric chemistry, climate, ecosystem studies, and human dimensions of global change. The context of climate change, including lessons to be gleaned from paleoclimatology. Human responses toâ€"and forcing ofâ€"projected global change. This book offers a comprehensive overview of global change research to date and provides a framework for answering urgent questions.

Remote Sensing plays a key role in monitoring the various manifestations of global climate change. It is used routinely in the assessment and mapping of biodiversity over large areas, in the monitoring of changes to the physical environment, in assessing threats to various components of natural systems, and in the identification of priority areas for conservation. This book presents the fundamentals of remote sensing technology, but rather than containing lengthy explanations of sensor specifications and operation, it concentrates instead on the application of the technology to key environmental systems. Each system forms the basis of a separate chapter, and each is illustrated by real world case studies and examples. Readership The book is intended for advanced undergraduate and graduate students in earth science, environmental science, or physical geography taking a course in environmental remote sensing. It will also be an invaluable reference for environmental scientists and managers who require an overview of the use of remote sensing in monitoring and mapping environmental change at regional and global scales.

Experts discuss the risks global environmental change poses for the human security, including disaster and disease, violence, and increasing inequity. In recent years, scholars in international relations and other fields have begun to conceive of security more broadly, moving away from a state-centered concept of national security toward the idea of human security, which emphasizes the individual and human well-being. Viewing global environmental change through the lens of human security connects such problems as melting ice caps and carbon emissions to poverty, vulnerability, equity, and conflict. This book examines the complex social, health, and economic consequences of environmental change across the globe. In chapters that are both academically rigorous and policy relevant, the book discusses the connections of global environmental change to urban poverty, natural disasters (with a case study of Hurricane Katrina), violent conflict (with a study of the decade-long Nepalese civil war), population, gender, and development. The book makes clear the inadequacy of traditional understandings of security and shows how global environmental change is raising new, unavoidable questions of human insecurity, conflict, cooperation, and sustainable development.

The challenges to global order posed by rapid environmental change are increasingly recognized as defining features of our time. In this groundbreaking work, the concept of innovation is deployed to explore normative and institutional responses in international law to such environmental change by addressing two fundamental themes: first, whether law can foresee, prevent, and adapt to environmental transformations; and second, whether international legal responses to social, economic, and technological innovation can appropriately reflect the evolving needs of contemporary societies at national and international scales. Using a range of case studies, the contributions to this collection track innovation - descriptively, normatively, and as a process in and of itself - to explain international environmental law's functionality in the Anthropocene. This book should be read by anyone interested in the critical intersection of environmental and international law.

This book explores the connections between two of the most transformative processes of the twenty-first century, namely climate change and globalization. In this book, Leichenko and O'Brien present a conceptual framework for analyzing the interactions between these two processes, and illustrate, through case studies, how these interactions create situations of "double exposure." Drawing upon prominent recent and current climate-related events -- Hurricane Katrina in New Orleans, recurring droughts in India, and the melting of Arctic sea ice -- the case studies each demonstrate a different pathway of interaction between globalization and global environmental change. Through exploration of these pathways of double exposure, the book also shows how broader human security concerns including growing inequalities, growing vulnerabilities, and unsustainable rates of development are integrally connected to both processes of global change. The double exposure framework not only sheds light on the challenges raised by these two global processes, but also reveals possibilities for using the interactions to generate positive opportunities for action.
