This book confronts a major contemporary problem - the fear of overpopulation. The classic analysis from which the population debate derives, Malthus's "Essay on Population", has largely been discredited by empirical evidence, but a new argument, not identical with the Malthusian analysis but related to it, has appeared in recent years. Thus it is now widely believed that the world's burgeoning population will soon reach - may already have reached - a level at which it imposes an unsustainable pressure on the natural environment. Not only is it believed that it will be impossible to feed the population, but man's desperate efforts to provide for himself are threatening the ecosystem itself. While not denying the role birth control and other measures may have to play, the authors question whether overpopulation really is the main problem. They argue instead that the main factor is the inequitable distribution of the earth's natural resources, nature's gift to mankind. Thus a small minority of the world's population owns and enjoys the benefits of the great majority of the earth's natural resources, while the vast majority of the population is huddled together in overcrowded conditions (creating the illusion of overpopulation) on what remains, which is often poorer land, deteriorating with over-exploitation, thus exacerbating the situation, such as in the Amazon Basin or the Sahel. The authors argue that a new approach to property rights and taxation will have to be adopted if the apparent conflict between demography and ecology is to be resolved. This volume also goes beyond the conventional debate on resource exploitation. Space Age technology threatens the remaining commons - the oceans, the arctic regions and outer space - which dramatizes the urgency of the quest for a new approach.

Parks and Carrying Capacity is an important new work for faculty, graduate and undergraduate students, and researchers in outdoor recreation, park planning and management, and natural resource conservation and management, as well as for professional planners and managers involved with park and outdoor recreation related agencies and nongovernmental organizations.

Tackles one of the most enduring and contentious issues of positive political economy: common pool resource management.

This book is in the philosophical tradition that originated in the early 17th century with Grotius, the "father of international law". The most recentóand controversialóexpression of this debate began with the work of Professor Hardim, whose original paper in Science has since been reprinted in over 80 anthologies. These matters of jurisprudence and biology ought to resolve the problem of whether people, acting selfishly, exhaust finite resources. Since they believe that this is so, they proposed a remedy in terms of property rights. The Grotius/Hardin problematic has now re-emerged with greater urgency, thanks to the fact that Space Age technology has once again transported mankind to what are the final frontiersóand confronted him with the choices about how to tap virgin resources on the new "commons". The imminent prospect of exploration in, and exploitation of, the ocean beds, the arctic regions and outer space necessitate a new debate about social justice, economic efficiency and ecological conservation. Unfortunately, the debateóthus faróhas not been particularly illuminating or sensitive to the mistakes of the past. Commons Without Tragedy reopens this topic in the form of a dialogue between Hardin and the economists who are in the philosophical tradition of Henry George, with Andelson offering a new interpretation of Hardin's original thesis which Hardin himself has acknowledged in the most generous terms. Indeed Hardin's acknowledgement of the importance of George is most startling and dramatic. The debate is not exclusively located in the ethereal domain, for the controversy necessarily confronts difficult questions about existing problems of demographic pressure on the land-based resources that have already been privatized.

Garrett Hardin's seminal essay "The Tragedy of the Commons" appeared in 1968 and has been at the center of the debate on commonly owned ground or resources such as Western public grazing or the oceans. This is the second edition of a book exploring the issues raised in Hardin's essay. As scarce resources are increasingly strained. It is ever more crucial to identify those resources which are held in common and are therefore prone to "tragic" waste and abuses. The essay in this volume focus on alternate institutional approaches to managing these resources to prevent such tragedy.

Collective Behavior is the summary of the 2014 National Academies Keck Futures Initiative Conference on Collective Behavior. Participants were divided into fourteen interdisciplinary research teams. The teams spent nine hours over two days exploring diverse challenges at the interface of science, engineering, and medicine. The composition of the teams was intentionally diverse, to encourage the generation of new approaches by combining a range of different types of contributions. The teams included researchers from science, engineering, and medicine, as well as representatives from private and public funding agencies, universities, businesses, journals, and the science media. Researchers represented a wide range of experience - from postdoc to those well established in their careers - from a variety of disciplines that included science and engineering, medicine, physics, biology, economics, and behavioral science. The teams needed to address the challenge of communicating and working together from a diversity of expertise and perspectives as they attempted to solve a complicated, interdisciplinary problem in a relatively short time. This report highlights the presentations of the event and includes the team reports and pre-meeting materials.

Believe in climate change. Or don't. It doesn't matter. But you'd better understand this: the best route to rebuilding our economy, our cities, and our job markets, as well as assuring national security, is doing precisely what you would do if you were scared to death about climate change. Whether you're the head of a household or the CEO of a multinational corporation, embracing efficiency, innovation, renewables, carbon markets, and new technologies is the smartest decision you can make. It's the most profitable, too. And, oh yes—you'll help save the planet. In Climate Capitalism, L. Hunter Lovins, coauthor of the bestselling Natural Capitalism, and the sustainability expert Boyd Cohen prove that the future of capitalism in a recession-riddled, carbon-constrained world will be built on innovations that cutting-edge leaders are bringing to the market today. These companies are creating jobs and driving innovation. Climate Capitalism delivers hundreds of indepth case studies of international corporations, small businesses, NGOs, and municipalities to prove that energy efficiency and renewable resources are already driving prosperity. While highlighting business opportunities across a range of sectors—including energy, construction, transportation, and agriculture technologies—Lovins and Cohen also show why the ex–CIA director Jim Woolsey drives a solar-powered plugin hybrid vehicle. His bumper sticker says it all: "Osama bin Laden hates my car." Corporate executives, entrepreneurs, environmentalists, and concerned citizens alike will find profitable ideas within these pages. In ten information-packed chapters, Climate Capitalism gives tangible examples of early adopters across the globe who see that the low-carbon economy leads to increased profits and economic growth. It offers a clear and concise road map to the new energy economy and a cooler planet.
