How population change will transform our world
In How Population Will Transform Our World, Sarah Harper looks at fertility rates and age structures of populations in different regions of the world against the backdrop of urbanization and climate change, drawing out the profound implications and challenges for societies, economies, and the environment in the decades to come.

Empty planet : the shock of global population decline
\"For half a century, statisticians, pundits, and politicians have warned that a burgeoning planetary population will soon overwhelm the earth's resources. But a growing number of experts are sounding a different kind of alarm. Rather than growing exponentially, they argue, the global population is headed for a steep decline - and in many countries that decline has already begun. In Empty Planet, Ibbitson and Bricker find that a smaller global population will bring with it a number of benefits: fewer workers will command higher wages; the environment will improve; the risk of famine will wane; and falling birthrates in the developing world will bring greater affluence and autonomy for women. But enormous disruption lies ahead, too. We can already see the effects in Europe and parts of Asia, as aging populations and worker shortages weaken the economy and impose crippling demands on healthcare and social security. Canada and the United States are well-positioned to successfully navigate these coming demographic shifts--that is, unless growing isolationism and anti-immigrant backlash lead us to close ourselves off just as openness becomes more critical to our survival than ever before. Rigorously researched and deeply compelling, Empty Planet offers a vision of a future that we can no longer prevent--but one that we can shape, if we choose\"--Jacket.

Population aging : is Latin America ready?
The past half-century has seen enormous changes in the demographic makeup of Latin America and the Caribbean (LAC). In the 1950s, LAC had a small population of about 160 million people, less than today's population of Brazil. Two-thirds of Latin Americans lived in rural areas. Families were large and women had one of the highest fertility rates in the world, low levels of education, and few opportunities for work outside the household. Investments in health and education reached only a small fraction of the children, many of whom died before reaching age five. Since then, the size of the LAC population has tripled and the mostly rural population has been transformed into a largely urban population. There have been steep reductions in child mortality, and investments in health and education have increased, today reaching a majority of children. Fertility has been more than halved and the opportunities for women in education and for work outside the household have improved significantly. Life expectancy has grown by 22 years. Less obvious to the casual observer, but of significance for policy makers, a population with a large fraction of dependent children has evolved into a population with fewer dependents and a very large proportion of working-age adults. This overview seeks to introduce the reader to three groups of issues related to population aging in LAC. First is a group of issues related to the support of the aging and poverty in the life cycle. Second is the question of the health transition. Third is an understanding of the fiscal pressures that are likely to accompany population aging and to disentangle the role of demography from the role of policy in that process.

Ecological orbits : how planets move and populations grow
The main focus of the book is the presentation of the inertial view of population growth. This view provides a rather simple model for complex population dynamics, and is achieved at the level of the single species without invoking species interactions. An important part of the account is the maternal effect. Investment of mothers in the quality of their daughters makes the rate of reproduction of the current generation depend not only on the current environment, but also on the environment experienced by the previous generation.

Monitoring animal populations and their habitats
In the face of so many unprecedented changes in our environment, the pressure is on scientists to lead the way toward a more sustainable future. Written by a team of ecologists, Monitoring Animal Populations and Their Habitats: A Practitioner's Guide provides a framework that natural resource managers and researchers can use to design monitoring programs that will benefit future generations by distilling the information needed to make informed decisions. In addition, this text is valuable for undergraduate- and graduate-level courses that are focused on monitoring animal populations. With the aid of more than 90 illustrations and a four-page color insert, this book offers practical guidance for the entire monitoring process, from incorporating stakeholder input and data collection, to data management, analysis, and reporting. It establishes the basis for why, what, how, where, and when monitoring should be conducted; describes how to analyze and interpret the data; explains how to budget for monitoring efforts; and discusses how to assemble reports of use in decision-making. The book takes a multi-scaled and multi-taxa approach, focusing on monitoring vertebrate populations and upland habitats, but the recommendations and suggestions presented are applicable to a variety of monitoring programs. Lastly, the book explores the future of monitoring techniques, enabling researchers to better plan for the future of wildlife populations and their habitats. Monitoring Animal Populations and Their Habitats: A Practitioner's Guide furthers the goal of achieving a world in which biodiversity is allowed to evolve and flourish in the face of such uncertainties as climate change, invasive species proliferation, land use expansion, and population growth.

Social Bodies
Using as his example post-World War I Italy and the government's interest in the size, growth rate, and \"vitality\" of its national population, David Horn suggests a genealogy for our present understanding of procreation as a site for technological intervention and political contestation.Social Bodieslooks at how population and reproductive bodies came to be the objects of new sciences, technologies, and government policies during this period. It examines the linked scientific constructions of Italian society as a body threatened by the \"disease\" of infertility, and of women and men associalbodies--located neither in nature nor in the private sphere, but in that modern domain of knowledge and intervention carved out by statistics, sociology, social hygiene, and social work.
Situated at the intersection of anthropology, cultural studies, and feminist studies of science, the book explores the interrelated factors that produced the practices of reason we call social science and social planning. David Horn draws on many sources to analyze the discourses and practices of \"social experts,\" the resistance these encountered, and the often unintended effects of the new objectification of bodies and populations. He shows how science, while affirming that maternity was part of woman's \"nature,\" also worked to remove reproduction from the domain of the natural, making it an object of technological intervention. This reconstitution of bodies through the sciences and technologies of the social, Horn argues, continues to have material consequences for women and men throughout the West.
