Precaution, environmental science, and preventive public policy Joel A. Tickner 0 Resenhas Island Press, 2003 - 406 páginas The "precautionary principle"-the idea that society should guard against potentially harmful activities even if some cause and effect relationships have not been fully established-has often been attacked for being unscientific. However leading scientists studying the issue have begun to make the case that the precautionary principle is in fact science based, and that it creates a need for more rigorous and transparent science in examining complex and uncertain environmental risks.Precaution, Environmental Science, and Preventive Public Policy is the first book to explore the role of science in developing a more precautionary approach to environmental and public health policy. The book brings together leading scientists, legal experts, philosophers, environmental health professionals, and environmentalists to offer a multi-disciplinary perspective on the controversial debate over science and precaution. The book:discusses the critical need for science in promoting sustainabilityoutlines the ethical imperative of a more precautionary science and the philosophical foundations of that new approachconsiders some of the ways in which the current conduct of environmental science works against precautionary policiesexamines how the role and use of science differs across cultures and political systemsprovides the components of an approach to environmental science that more effectively supports precautionary decisionsThe book also offers case studies that consider various types of uncertainty and sets forth a framework for evaluating and addressing uncertainty in decision-making.Contributors include Juan Almendares, Katherine Barrett, Kamaljit Bawa, Finn Bro-Rasmussen, Donald Brown, Theofanis Christoforou, Terry Collins, Barry Commoner, Carl Cranor, Stephen Dovers, David Gee, Elizabeth Guillette, Cato ten Hallers-Tjabbes, James Huff, Matthias Kais

Precautionary tools for reshaping environmental policy Nancy J. Myers, Carolyn Raffensperger 0 Resenhas MIT Press, 2006 - 339 páginas The precautionary principle calls for taking action against threatened harm to people and ecosystems even in the absence of full scientific certainty. The rationale is that modern technologies and human activities can inflict long-term, global-scale environmental damage and that conclusive scientific evidence of such damage may be available too late to avert it. The precautionary principle asks whether harm can be prevented instead of assessing degrees of "acceptable" risk. This book provides a toolkit for applying precautionary concepts to reshape environmental policies at all levels. Its compendium of regulatory options, detailed examples, wide-ranging case studies, and theoretical background provides both citizens and policymakers with the basis for acting on any issue in any situation-whether it's pesticide use at local schools or a new international regulatory system for chemicals. Precautionary Tools for Reshaping Environmental Policy describes the analytical and ethical bases of the precautionary principle as well as practical options for implementing it. It provides a "precautionary checklist" that can serve as a springboard for discussion and decisions. And it offers a variety of case studies that show the precautionary principle in action-from elk and cattle farming to marine fisheries, from the protection of indigenous cultures against bioprospecting to the restoration of the federal court system as a safety net for people harmed by products and chemicals. A hands-on interdisciplinary guide, the book demonstrates the advantages of a precautionary approach and addresses criticisms that have been leveled against it.

Normal accidents: living with high-risk technologies Charles Perrow 2 Resenhas Princeton University Press, 1999 - 451 páginas Normal Accidents analyzes the social side of technological risk. Charles Perrow argues that the conventional engineering approach to ensuring safety--building in more warnings and safeguards--fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk--complex versus linear interactions, and tight versus loose coupling--this book provides a powerful framework for analyzing risks and the organizations that insist we run them.The first edition fulfilled one reviewer's prediction that it "may mark the beginning of accident research." In the new afterword to this edition Perrow reviews the extensive work on the major accidents of the last fifteen years, including Bhopal, Chernobyl, and the Challenger disaster. The new postscript probes what the author considers to be the "quintessential 'Normal Accident'" of our time: the Y2K computer problem.

672. Steven Shavell, The Corrective Tax versus Liability As Solutions to the Problem of Harmful Externalities, 7/10. Abstract: Although the corrective tax has long been viewed by economists as a theoretically desirable remedy for the problem of harmful externalities, its actual use has been limited, mainly to the domain of pollution. Liability, in contrast, has great importance in controlling harmful externalities. I compare the tax and liability here in theory and suggest that the conclusions help to explain the observed predominance of liability over taxation, except in the area of pollution. The following factors are emphasized in the analysis: inefficiency of incentives under taxes when, as would be typical, it would be impractical for the state to incorporate into taxes all of the variables that significantly affect expected harm; efficiency of incentives under strict liability, which requires only that actual harms be measured; efficiency of incentives to exercise precautions under the negligence rule; administrative cost advantages of liability deriving from its being applied only when harm occurs; and dilution of incentives under liability when suit would be unlikely or injurers would not be able to pay fully for harms caused.

In this paper we analyze the factors that should be considered when allocating a given policy function at a particular level of government and how these factors affect the growth and evolution of multi-level governments. After discussing the interplay of economies of scale, economies of scope, and heterogeneity of preferences in determining the optimal level of legal intervention, we show that the subsidiarity principle can have mixed effects as a firewall against progressive centralization. Our economic model of subsidiarity reveals that once some functions become centralized, further centralization becomes easier and often unavoidable. Contrary to its intended function, a piecemeal application of the subsidiarity principle can trigger a path-dependent avalanche of centralization, turning subsidiarity into a self-defeating statement of principle.
