This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Available in PDF, EPUB and Kindle. Book excerpt: This book has a strong theoretical focus and is unique in addressing both mortality and fertility over the full span of human history. It examines the demographic transition in the change in the human condition from high mortality and high fertility to low mortality and low fertility. It asks if fluctuating populations is a new phenomenon, or if there has long been an inherent tendency in Man to maximize survival and to control family size.

Download or read book Democracies in Flux written by Robert D. Putnam and published by Oxford University Press. This book was released on 2002-08-15 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his national bestseller Bowling Alone, Robert Putnam illuminated the decline of social capital in the US. Now, in Democracies in Flux, Putnam brings together a group of leading scholars who broaden his findings as they examine the state of social capital in eight advanced democracies around the world. The book is packed with many intriguing revelations. The contributors note, for instance, that waning participation in unions, churches, and political parties seems to be virtually universal, a troubling discovery as these forms of social capital are especially important for empowering less educated, less affluent portions of the population. Indeed, in general, the researchers found more social grouping among the affluent than among the working classes and they find evidence of a younger generation that is singularly uninterested in politics, distrustful both of politicians and of others, cynical about public affairs, and less inclined to participate in enduring social organizations. Yet social capital appears as strong as ever in Sweden, where 40% of the adult population participate in "study circles"--small groups who meet weekly for educational discussions. Social capital--good will, fellowship, sympathy, and social intercourse--is vitally important both for the health of our communities and for our own physical and psychological well being. Offering a panoramic look at social capital around the world, this book makes an important contribution to our understanding of these phenomena and why they are important in today's world.

Book excerpt: A dazzling new history of the irrepressible demographic changes and mass migrations that have made and unmade nations, continents, and empires The rise and fall of the British Empire; the emergence of America as a superpower; the ebb and flow of global challenges from Nazi Germany, Imperial Japan, and Soviet Russia. These are the headlines of history, but they cannot be properly grasped without understanding the role that population has played. The Human Tide shows how periods of rapid population transition--a phenomenon that first emerged in the British Isles but gradually spread across the globe--shaped the course of world history. Demography--the study of population--is the key to unlocking an understanding of the world we live in and how we got here. Demographic changes explain why the Arab Spring came and went, how China rose so meteorically, and why Britain voted for Brexit and America for Donald Trump. Sweeping from Europe to the Americas, China, East Asia, the Middle East, and North Africa, The Human Tide is a panoramic view of the sheer power of numbers.

Download or read book Growing Populations, Changing Landscapes written by National Academy of Sciences and published by National Academies Press. This book was released on 2001-06-12 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world's population exceeds an incredible 6 billion people, governmentsâ€"and scientistsâ€"everywhere are concerned about the prospects for sustainable development. The science academies of the three most populous countries have joined forces in an unprecedented effort to understand the linkage between population growth and land-use change, and its implications for the future. By examining six sites ranging from agricultural to intensely urban to areas in transition, the multinational study panel asks how population growth and consumption directly cause land-use change, and explore the general nature of the forces driving the transformations. Growing Populations, Changing Landscapes explains how disparate government policies with unintended consequences and globalization effects that link local land-use changes to consumption patterns and labor policies in distant countries can be far more influential than simple numerical population increases. Recognizing the importance of these linkages can be a significant step toward more effective environmental management.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehending and modelling biomass production, nutrient, and water fluxes in biological systems requires understanding control mechanisms at various levels of organiztion. This new book, with 16 pages of four-colorplates, compares patterns and mechanisms of regulation-starting from enzyme reactions and ending at the population and ecosystem level. By doing so, the book investigates the general principles of how fluxes are adjusted and regulated. Such principles areessential for preparing effective models and for predicting human impacts on ecosystems. Flux Control in Biological Systems: From Enzymes to Populations and Ecosystems will be an essential personal library addition for student and professional environmental biologists, ecologists, physiologists, biochemists, botanists, microbiologists, soil scientists, and zoologists; as well as anyone who investigate patterns of matter and energy transfer in biological systems of different levels of complexity.* Presents the mechanisms of flux control* Explains the similarities of flux control at various levels of complexity and organization* Demonstrates how fluxes are adjusted in complex systems of interacting groups of organisms

Download or read book The Demographic Transition written by Jean-Claude Chesnais and published by . This book was released on 1992 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demographic transition constitutes one of the most fundamental modern historical changes; people live much longer, have fewer children, and experience higher mobility. This book examines the basic mechanisms behind the modernisation of demographic behaviour. The author has marshalled an impressive array of statistical material relating to sixty-seven countries, half of them less developed countries. Most of the tables are time-series, covering many decades and sometimes go back to the nineteenth, and even eighteenth centuries. The whole sweep of western experience is dealt with here impartially. Though technically sophisticated, the book also covers issues of interpretation and analysis. The author puts forward a number of challenging propositions: mortality decrease is shown to necessarily precede fertility and decline, so-called execptions being simply false exceptions. He shows how the decline of fertility is dependent on important and manifold social transformations. The strong connections between international migration and the course of demographic transition are demonstrated, as is the fact that less developed countries are following the same general patterns as MDCs. There is also discussion of why the theory of demographic transition must include the effect of population changes on the economic progress of society.
