The growing perception of the public and politicians that life is extremely risky has led to a dramatic and increasing interest in risk analysis. The risks may be very diverse as demonstrated by the range of subjects covered at the annual meetings of the Society for Risk Analysis. There is a need to pause and see how well the present approaches are serving the nation. The theme, "Setting National Priorities," which was chosen for the 1987 SRA Annual Meeting, reflects the concern that in dealing with individual kinds of risks, society may be more concerned with the trees than the forest. It is surprising how little attention is being given to the holistic aspects of risk. Who, for instance, is responsible for a national strategy to manage the reduction of health or other risks? Individual agencies have the responsibility for specific patterns of exposure, but these are not integrated and balanced to determine how the nation as a whole can obtain the greatest benefit for the very large investment which is made in risk-related research and analysis.
The regulation of potentially hazardous substances has become a controversial issue. This volume evaluates past efforts to develop and use risk assessment guidelines, reviews the experience of regulatory agencies with different administrative arrangements for risk assessment, and evaluates various proposals to modify procedures. The book's conclusions and recommendations can be applied across the entire field of environmental health.
For any government agency, the distribution of available resources among problems or programs is crucially important. Agencies, however, typically lack a self-conscious process for examining priorities, much less an explicit method for defining what priorities should be. Worst Things First? illustrates the controversy that ensues when previously implicit administrative processes are made explicit and subjected to critical examination. It reveals surprising limitations to quantitative risk assessment as an instrument for precise tuning of policy judgments. The book also demonstrates the strength of political and social forces opposing the exclusive use of risk assessment in setting environmental priorities.
The budgetary squeeze of the 1990s has made it obvious that the government cannot address every possible environmental problem. Comparative risk assessment (CRA) is increasingly advanced as the means for setting realistic priorities. RFF's Center for Risk Management commissioned background papers from leading experts on CRA for a meeting with federal regulatory officials. Comparing Environmental Risks presents the revised papers of this workshop. Representing the state of the art on programmatic CRA, its methodological analyses and practical recommendations will be invaluable to government officials, independent analysts, and anyone studying environmental policy.
Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
Adolescents obviously do not always act in ways that serve their own best interests, even as defined by them. Sometimes their perception of their own risks, even of survival to adulthood, is larger than the reality; in other cases, they underestimate the risks of particular actions or behaviors. It is possible, indeed likely, that some adolescents engage in risky behaviors because of a perception of invulnerabilityâ€"the current conventional wisdom of adults' views of adolescent behavior. Others, however, take risks because they feel vulnerable to a point approaching hopelessness. In either case, these perceptions can prompt adolescents to make poor decisions that can put them at risk and leave them vulnerable to physical or psychological harm that may have a negative impact on their long-term health and viability. A small planning group was formed to develop a workshop on reconceptualizing adolescent risk and vulnerability. With funding from Carnegie Corporation of New York, the Workshop on Adolescent Risk and Vulnerability: Setting Priorities took place on March 13, 2001, in Washington, DC. The workshop's goal was to put into perspective the total burden of vulnerability that adolescents face, taking advantage of the growing societal concern for adolescents, the need to set priorities for meeting adolescents' needs, and the opportunity to apply decision-making perspectives to this critical area. This report summarizes the workshop.
Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond. Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami. According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.
Accurate assessment of environmental hazards and related risks is a primary prerequisite for effective environmental health protection, at both the individual and collective level. National and regional policies on environmental health need to be guided by knowledge about the risks to the populations involved; as the Environmental Action Plan for Europe notes, 'priority setting requires the comparative assessment of risks to health of different environmental factors against the cost of controlling them.' In recent years this has assumed particular importance, for with the encouragement of the World Health Organisation (WHO), all countries in Europe are committed to producing National Environmental Health Action Plans (NEHAPs), which will define priorities and targets for environmental health and the actions needed to achieve them. Reliable information on risks is clearly fundamantal to this process. Individual risk assessment is no less important in this context. Much of the responsibility and capacity to improve public health lies ultimately in the choices (e.g. about diet, smoking, alcohol consumption, sexual activities, sporting activities, travel mode, place of residence and occupation) which we make as individuals. If we are to improve and protect our own health, therefore, and in so doing play our personal role in achieving the targets set by these Plans, we need to be guided by a clear understanding of the risks involved.
