Population Dynamics And Climate Change

This book broadens and deepens understanding of a wide range of population-climate change linkages. Incorporating population dynamics into research, policymaking and advocacy around climate change is critical for understanding trajectory of global greenhouse gas emissions, for developing and implementing adaptation plans and thus for global and national efforts to curtail this threat. The papers in this volume provide a substantive and methodological guide to the current state of knowledge on issues such as population growth and size and emissions; population vulnerability and adaptation linked to health, gender disparities and children; migration and urbanization; and the data and analytical needs for the next stages of policy-relevant research.

This report discusses the relationship between population and environmental change, the forces that mediate this relationship, and how population dynamics specifically affect climate change and land-use change.

Population and Climate Change provides the first systematic in-depth treatment of links between two major themes of the 21st century: population growth (and associated demographic trends such as aging) and climate change. It is written by a multidisciplinary team of authors from the International Institute for Applied Systems Analysis who integrate both natural science and social science perspectives in a way that is comprehensible to members of both communities. The book will be of primary interest to researchers in the fields of climate change, demography, and economics. It will also be useful to policy-makers and NGOs dealing with issues of population dynamics and climate change, and to teachers and students in courses such as environmental studies, demography, climatology, economics, earth systems science, and international relations.

The Earth's population doubled between 1960 and 1999, increasing from three billion to six billion people. During that period, human-induced changes in the global environment accelerated in unprecedented fashion. Given continued population growth and environmental degradation, it has become paramount that we deepen our understanding of the role played by human population dynamics in environmental change. Drawing from the scientific literature, this report presents a synthesis of what is known about the role played by human population factors in environmental change. Specifically, the report discusses the following: ̂The relationship between population factors-size, distribution, and composition-and environmental change. The primary forces that mediate this relationship: technology, the institutional and policy contexts, and cultural factors. ̂Two specific aspects of environmental change that are affected by population dynamics: climate change and land-use change. Implications for policy and further research.

This handbook presents a timely and comprehensive overview of theory, data, methods and research findings that connect human population dynamics and environmental context. It presents regional summaries of empirical findings on migration and environmental connections and summarizes environmental impacts of migration – such as urbanization and deforestation. It also offers background on the health implications of environmental conditions such as climate change, natural disasters, scarcity of natural resources, as well as on resource scarcity and fertility, gender considerations in population and environment, and the connections between population size, growth, composition and carbon emissions. This handbook helps readers to better understand the complexities within population-environment connections, in addition to some of the opportunities and challenges within environmental demography. As such this collection is an invaluable resource for students, researchers, and policy analysts in the areas of demography, migration, fertility, health and mortality, as well as environmental, global and development studies.

The report draws on new studies that document the environmental pressures from soaring population growth. It also reports on the unique role that women can play in alleviating those pressures, even as women are disproportionally affected by the adverse effects of climate change. Finally, the report argues that humanity ultimately will need to slow population growth to tackle rising global temperatures, and that the only way to do this is by improving the well-being of women worldwide.

A flurry of extreme weather events, together with projections that grow more somber with every new scientific advance, have dramatically highlighted the need to respond more effectively to the threats already upon humankind. In the midst of a rapidly expanding global adaptation agenda, it is of primary importance to get adaptation and its constituent parts right, in order to generate the most appropriate and effective interventions. Adapting to episodes after they occur is no longer sufficient; we increasingly need to anticipate and reduce the suffering and the enormously damaging impacts of potential coming events. This book addresses a major gap in adaptation efforts to date by pointing to the vital role that an understanding of population dynamics and an extensive use of demographic data have in developing pre-emptive and effective adaptation policies and practices. Politics and an oversimplified understanding of demographic dynamics have long kept population issues out of serious discussions in the framework of climate negotiations. Within adaptation actions, however, this is beginning to change, and this volume is intended to provide a framework for taking that change forward, towards better, more evidence-based adaptation. It provides key concepts linking demography and adaptation, data foundations and techniques for analyzing climate vulnerability, as well as case studies where these concepts and analyses illuminate who is vulnerable and how to help build their resilience.

Rising temperatures are affecting organisms in all of Earth's biomes, but the complexity of ecological responses to climate change has hampered the development of a conceptually unified treatment of them. In a remarkably comprehensive synthesis, this book presents past, ongoing, and future ecological responses to climate change in the context of two simplifying hypotheses, facilitation and interference, arguing that biotic interactions may be the primary driver of ecological responses to climate change across all levels of biological organization. Eric Post's synthesis and analyses of ecological consequences of climate change extend from the Late Pleistocene to the present, and through the next century of projected warming. His investigation is grounded in classic themes of enduring interest in ecology, but developed around novel conceptual and mathematical models of observed and predicted dynamics. Using stability theory as a recurring theme, Post argues that the magnitude of climatic variability may be just as important as the magnitude and direction of change in determining whether populations, communities, and species persist. He urges a more refined consideration of species interactions, emphasizing important distinctions between lateral and vertical interactions and their disparate roles in shaping responses of populations, communities, and ecosystems to climate change.
