Hurricane- and coastal-storm-related losses have increased substantially during the past century, largely due to increases in population and development in the most susceptible coastal areas. Climate change poses additional threats to coastal communities from sea level rise and possible increases in strength of the largest hurricanes. Several large cities in the United States have extensive assets at risk to coastal storms, along with countless smaller cities and developed areas. The devastation from Superstorm Sandy has heightened the nation's awareness of these vulnerabilities. What can we do to better prepare for and respond to the increasing risks of loss? Reducing Coastal Risk on the East and Gulf Coasts reviews the coastal risk-reduction strategies and levels of protection that have been used along the United States East and Gulf Coasts to reduce the impacts of coastal flooding associated with storm surges. This report evaluates their effectiveness in terms of economic return, protection of life safety, and minimization of environmental effects. According to this report, the vast majority of the funding for coastal risk-related issues is provided only after a disaster occurs. This report calls for the development of a national vision for coastal risk management that includes a long-term view, regional solutions, and recognition of the full array of economic, social, environmental, and life-safety benefits that come from risk reduction efforts. To support this vision, Reducing Coastal Risk states that a national coastal risk assessment is needed to identify those areas with the greatest risks that are high priorities for risk reduction efforts. The report discusses the implications of expanding the extent and levels of coastal storm surge protection in terms of operation and maintenance costs and the availability of resources. Reducing Coastal Risk recommends that benefit-cost analysis, constrained by acceptable risk criteria and other important environmental and social factors, be used as a framework for evaluating national investments in coastal risk reduction. The recommendations of this report will assist engineers, planners and policy makers at national, regional, state, and local levels to move from a nation that is primarily reactive to coastal disasters to one that invests wisely in coastal risk reduction and builds resilience among coastal communities.

More and more of the nation's vast coastlines are being filled with homes and vacation resorts. The result is an increasing number of structures built on erosion-prone shoresâ€"with many of these structures facing collapse or damage. In response to mounting property losses, Congress has given the Federal Emergency Management Agency responsibility for incorporating coastal erosion into its National Flood Insurance Program (NFIP). This book from the National Research Council addresses the immediate question of how to develop an erosion insurance programâ€"as well as the larger issues raised by the continually changing face of our nation's shorelines. Managing Coastal Erosion explores major questions surrounding a national policy on coastal erosion: Should the federal government be in the business of protecting developers and individuals who build in erosion-prone coastal areas? How should such a program be implemented? Can it prompt more responsible management of coastal areas? The volume provides federal policymakers, state floodplain and resource managers, civil engineers, environmental groups, marine specialists, development companies, and researchers with invaluable information about the natural processes of coastal erosion and the effect of human activity on those processes. The book also details the workings of the NFIP, lessons to be learned from numerous state coastal management programs, and much more.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

This collection contains 79 papers addressing the challenges and lessons learned along the coastlines of the world, presented at the 2011 Solutions to Coastal Disasters Conference, held in Anchorage, Alaska, June 25-29, 2011.

Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

This century has seen the costliest hurricanes in U.S. history—but who bears the brunt of these monster storms? Consider this: Five of the most expensive hurricanes in history have made landfall since 2005: Katrina ($160 billion), Ike ($40 billion), Sandy ($72 billion), Harvey ($125 billion), and Maria ($90 billion). With more property than ever in harm’s way, and the planet and oceans warming dangerously, it won’t be long before we see a $250 billion hurricane. Why? Because Americans have built $3 trillion worth of property in some of the riskiest places on earth: barrier islands and coastal floodplains. And they have been encouraged to do so by what Gilbert M. Gaul reveals in The Geography of Risk to be a confounding array of federal subsidies, tax breaks, low-interest loans, grants, and government flood insurance that shift the risk of life at the beach from private investors to public taxpayers, radically distorting common notions of risk. These federal incentives, Gaul argues, have resulted in one of the worst planning failures in American history, and the costs to taxpayers are reaching unsustainable levels. We have become responsible for a shocking array of coastal amenities: new roads, bridges, buildings, streetlights, tennis courts, marinas, gazebos, and even spoiled food after hurricanes. The Geography of Risk will forever change the way you think about the coasts, from the clash between economic interests and nature, to the heated politics of regulators and developers.

Coastal Flood Risk Reduction: The Netherlands and the U.S. Upper Texas Coast represents the culmination of a 5-year international research and education partnership funded by the US National Science Foundation (NSF) and more than 10 years of collaboration between Dutch and U.S. flood experts on the basic issue of how to protect society from growing flood risks. Multiple case studies integrating the fields of engineering, hydrology, landscape architecture, economics, and planning address the underlying characteristics of physical flood risks and their prediction; human communities and the associated built environment; physical, social, and built-environment variables; and mitigation techniques. In recognition of the lack of systematic research and the growing societal need to better understand flood impacts, this edited book provides an in-depth, comparative evaluation of flood problems and solutions in two key places: the Netherlands and the U.S. Upper Texas Coast. Both regions are extremely flood-prone and have experienced continual adverse impacts throughout their histories. For researchers in flood management, geographers, hydrologists, environmental studies, and social science as well as policymakers and decision-makers in flood management authorities and related industries, this book provides an essential resource. - Introduces integrated comparative work on flood risk reduction and management across disciplines and international boundaries - Presents chapters written by dozens of experts across six U.S. and Dutch universities that have formally participated in the international research and education program funded by the U.S. National Science Foundation (NSF) - Provides a basis for understanding and mitigating flood risk over a range of necessary perspectives, from modeling inputs to design solutions - Integrates cutting-edge scientific methods and state-of-the-art knowledge with examples of specific solutions and how they are being implemented in each national case study
