October 31, 2011, marked an uneasy milestone for Planet Earth. On this day, the global population surpassed seven billion. What does that mean for a world that, until the nineteenth century, was home to less than one billion people? Experts say it means the planet is in trouble. Some wonder if Earth will even be able to sustain human life at its current rate of growth. Will there be enough food for everyone? Will conflicts over land increase? How will the environment be affected? Can humanity survive the predicted disasters? More than a simple case of running out of space, the population crisis is interwoven with a host of other issues?from climate change and resource management to war, disease, and poverty. Discover how all these factors converge to place an entire planet in crisis mode?and explore what sort of responses that crisis may require.
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.
This book addresses nine relevant questions: Will population growth reduce the growth rate of per capita income because it reduces the per capita availability of exhaustible resources? How about for renewable resources? Will population growth aggravate degradation of the natural environment? Does more rapid growth reduce worker output and consumption? Do rapid growth and greater density lead to productivity gains through scale economies and thereby raise per capita income? Will rapid population growth reduce per capita levels of education and health? Will it increase inequality of income distribution? Is it an important source of labor problems and city population absorption? And, finally, do the economic effects of population growth justify government programs to reduce fertility that go beyond the provision of family planning services?
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.
Examines the factors which limit human economic and population growth and outlines the steps necessary for achieving a balance between population and production. Bibliogs
This book examines potential economic opportunities that countries can experience when fertility rates fall and the average life expectancy of the working age population increases. It presents detailed demographic and economic analysis of middle-income countries throughout the world in order to show how these countries can take advantage of this demographic bonus. The book first traces the common link between policies that contribute to fertility transition as well as create the right kind of environment for reaping the benefit of demographic dividend. Next, it explores different countries and regions who are at different levels of development. It assesses the long term impact of gender equality on economic growth and development in Latin America; describes the life-cycle saving patterns of Mexican households; and examines demographic determinants of economic growth in BRICS. The book also offers demographic and economic analysis of the Mediterranean area, Sub-Saharan Africa, and New Zealand. The comparison between the different territorial contexts allow for the identification of three typologies of demographic dividend: the first dividend, when the working population grows faster than total population, the second dividend, as active generations get older and invest their savings in the production system of their country, and the third dividend, based on the coexistence of two populations age structure strongly contrasting. Overall, this book argues for the need to capitalize on the opportunities that come from the demographic dividend by investing heavily in education programs, training programs for the population working age, health programs, the creation of health insurance systems as well as programs to reduce or increase fertility levels.
This book examines the nature and significance of the impact of population growth on the weIl-being of developing countries-in particular, the effects on economic growth, education, health, food supply, housing, poverty, and the environment. In addition, because family planning programmes often significantly affect population growth, the study examines the impacts of family planning on fertility and health, and the human rights implications of family planning programmes. In considering the book's conclusions about the impact of population growth on development, four caveats should be noted. First, the effects of population growth vary from place to place and over time. Thus, blanket statements about overall effects often cannot be made. Where possible, the authors note the contexts in which population effects are strongest and weakest. Second, all of the outcomes examined in this book are influenced by factors other than population growth. Moreover, the impact of population growth may itself vary according to the presence or absence of other factors. This again makes bl anket statements about the effects of population growth difficult. Throughout the chapters, the authors try to identify other relevant factors that influence the outcomes we discuss or that influence the impact of population growth on those outcomes.
Hospitals and nursing homes are responding to changes in the health care system by modifying staffing levels and the mix of nursing personnel. But do these changes endanger the quality of patient care? Do nursing staff suffer increased rates of injury, illness, or stress because of changing workplace demands? These questions are addressed in Nursing Staff in Hospitals and Nursing Homes, a thorough and authoritative look at today's health care system that also takes a long-term view of staffing needs for nursing as the nation moves into the next century. The committee draws fundamental conclusions about the evolving role of nurses in hospitals and nursing homes and presents recommendations about staffing decisions, nursing training, measurement of quality, reimbursement, and other areas. The volume also discusses work-related injuries, violence toward and abuse of nursing staffs, and stress among nursing personnelâ€"and examines whether these problems are related to staffing levels. Included is a readable overview of the underlying trends in health care that have given rise to urgent questions about nurse staffing: population changes, budget pressures, and the introduction of new technologies. Nursing Staff in Hospitals and Nursing Homes provides a straightforward examination of complex and sensitive issues surround the role and value of nursing on our health care system.
Comparison with stationary and very fast rates of population growth shows modern population grwoth to have long-run positive effects on the standards of living. This is Julian Simon's contention, and he provides support for its validity in both more and less-developed countries. He notes that since each person constitutes a burden in the short run, whether population growth is judged good or bad depends on the importance the short run is accorded relative to the long run. The author first analyzes empirical data, formulating his conclusions using simulation models. He then reviews our knowledge of the effect of economic level upon population growth. A final section of his book considers the framework of welfare economics and values within which population policy decisions are now made. He finds that the implications of policy decisions can prove inconsistent with the values that prompt their recommendation. Originally published in 1977.
