Environmentalists devote little attention at the moment to the size and growth of the human population. To counter this neglect, the monograph (i) includes original graphs showing population size and growth since 1920 in the world as a whole and the United States; (ii) assembles evidence tying the increasing number of people to ecosystem deterioration and its societal consequences; and (iii) analyzes sample-survey data to ascertain whether the current disregard of population pressures by U.S. environmentalists reflects the thinking of Americans generally. However, even if a nation took steps primarily intended to lower childbearing and immigration, the findings of social science research indicate that the steps would not have a substantial, lasting impact. The discussion, which suggests an indirect way by which government may reduce fertility, underlines for environmental scholars the importance of studying their subject in a multidisciplinary, collaborative setting.
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.
The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
From the depths of the oceans to the highest reaches of the atmosphere, the human impact on the environment is significant and undeniable. These forms of global and local environmental change collectively appear to signal the arrival of a new geological epoch: the Anthropocene. This is a geological era defined not by natural environmental fluctuations or meteorite impacts, but by collective actions of humanity. Environmental Transformations offers a concise and accessible introduction to the human practices and systems that sustain the Anthropocene. It combines accounts of the carbon cycle, global heat balances, entropy, hydrology, forest ecology and pedology, with theories of demography, war, industrial capitalism, urban development, state theory and behavioural psychology. This book charts the particular role of geography and geographers in studying environmental change and its human drivers. It provides a review of critical theories that can help to uncover the socio-economic and political factors that influence environmental change. It also explores key issues in contemporary environmental studies, such as resource use, water scarcity, climate change, industrial pollution and deforestation. These issues are ‘mapped’ through a series of geographical case studies to illustrate the particular value of geographical notions of space, place and scale, in uncovering the complex nature of environmental change in different socio-economic, political and cultural contexts. Finally, the book considers the different ways in which nations, communities and individuals around the world are adapting to environmental change in the twenty-first century. Particular attention is given throughout to the uneven geographical opportunities that different communities have to adapt to environmental change and to the questions of social justice this situation raises. This book encourages students to engage in the scientific uncertainties that surround the study of environmental change, while also discussing both pessimistic and more optimistic views on the ability of humanity to address the environmental challenges of our current era.
This book presents and develops the basic methods and models that are used by demographers to study the behaviour of human populations. The procedures are clearly and concisely developed from first principles and extensive applications are presented.
Demography is not destiny. As Giacomo Casanova explained over two centuries ago: 'There is no such thing as destiny. We ourselves shape our own lives.' Today we are shaping them and our societies more than ever before. Globally, we have never had fewer children per adult: our population is about to stabilize, though we do not know when or at what number, or what will happen after that. It will be the result of billions of very private decisions influenced in turn by multiple events and policies, some more unpredictable than others. More people are moving further around the world than ever before: we too often see that as frightening, rather than as indicating greater freedom. Similarly, we too often lament greater ageing, rather than recognizing it as a tremendous human achievement with numerous benefits to which we must adapt. Demography comes to the fore most positively when we see that we have choices, when we understand variation and when we are not deterministic in our prescriptions. The study of demography has for too long been dominated by pessimism and inhuman, simplistic accounting. As this fascinating and persuasive overview demonstrates, how we understand our demography needs to change again.
The Earth has entered a new age—the Anthropocene—in which humans are the most powerful influence on global ecology. Since the mid-twentieth century, the accelerating pace of energy use, greenhouse gas emissions, and population growth has thrust the planet into a massive uncontrolled experiment. The Great Acceleration explains its causes and consequences, highlighting the role of energy systems, as well as trends in climate change, urbanization, and environmentalism. More than any other factor, human dependence on fossil fuels inaugurated the Anthropocene. Before 1700, people used little in the way of fossil fuels, but over the next two hundred years coal became the most important energy source. When oil entered the picture, coal and oil soon accounted for seventy-five percent of human energy use. This allowed far more economic activity and produced a higher standard of living than people had ever known—but it created far more ecological disruption. We are now living in the Anthropocene. The period from 1945 to the present represents the most anomalous period in the history of humanity’s relationship with the biosphere. Three-quarters of the carbon dioxide humans have contributed to the atmosphere has accumulated since World War II ended, and the number of people on Earth has nearly tripled. So far, humans have dramatically altered the planet’s biogeochemical systems without consciously managing them. If we try to control these systems through geoengineering, we will inaugurate another stage of the Anthropocene. Where it might lead, no one can say for sure.
This book captures some of the emergent topics and methods in demography at the turn of this 21st century. Like all social sciences, the concerns and tools of demography must evolve with the times. As new technologies expand data management opportunities, and as a changing world faces new demographic issues, the field of demographic research must expand as well. The chapters in the book rise to this challenge by embracing new questions or new approaches to classic questions about demographic processes and their link to development, including inequality, health, migration, and youth across the world.
