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.
Managed realignment has been a preferred coastal management strategy in England in the 21st century and has also been increasingly implemented elsewhere. Climate change and environmental and financial concerns have led to a shift from the traditional ‘hold-the-line’ approach of coastal protection towards more flexible soft engineering options. Managed realignment is a relatively new soft engineering alternative aiming to provide sustainable flood risk management with added environmental and socio-economic benefits by creating space for coastal habitats to develop more dynamically. The natural adaptive capacity of coastal habitats and the ecosystem services they provide underpin the sustainability of managed realignment. However, many definitions of managed realignment exist and the understanding of what the term actually represents in practice has evolved through time and varies regionally. This book clarifies the definitions and terminology used in the literature and proposes that managed realignment is used as a general term that encompasses the many different methods of implementation worldwide, including: removal, breach and realignment of defences; controlled tidal restoration (which includes regulated tidal exchange and controlled reduced tide); and managed retreat. These methods of implementation are explained and illustrated with examples from around the world. In addition to a general overview of emerging policies and current practices, specific chapters discuss approaches adopted in different locations, including the Netherlands, the UK and Maui (USA). The UK experience is presented from the perspectives of three sectors: the National Trust (a charity organisation that owns 10% of the coastline of England and Wales), the Environment Agency (the organisation responsible for implementing government policy concerning flood and erosion risk) and a private consultant involved in the planning, design and delivery of managed realignment projects. Taking a wider perspective to consider the range of implementation methods, the viability of managed realignment as a long-term coastal management strategy is discussed. Recent national and regional strategies worldwide give managed realignment an increasing role in climate change and flood risk management. Gaining stakeholders and public support is fundamental for the success of emerging coastal management strategies. However, public perception and stakeholders engagement are often cited as a factor limiting the wider uptake of managed realignment. Results from a recent survey are used to benchmark the current thinking about the potential, the performance and the limitations of managed realignment in the UK and elsewhere. Current opinions about managed realignment are often not clearly defined, partly due to many projects being relatively recent. There is a general perception of great potential to provide sustainable flood risk management with added environmental benefits. However, the views of stakeholders are considerably more negative and notably contrast with the views of practitioners and researchers. The only clear and dominant agreement across all groups of respondents is that better understanding about the long-term evolution of sites is needed.
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.
As with most shorelines around the world, New Jersey beaches are slowly, but inexorably, being eroded, threatening coastal structures and development. In some years more sand is deposited than removed, but all of the state's monitoring devices show that sea level is gradually rising and pushing the New Jersey shoreline inland. The shore is a valuable resource, and its natural, cultural, and economic attractions draw a multitude of permanent and temporary residents each year, extending housing and commercial development onto areas that were once swampland. Not surprisingly, development at the water's edge has been accompanied by an increasing exposure to the natural hazards of the coastal zone--erosion, flooding, and wind damage. In this book, Norbert Psuty and Douglas Ofiara incorporate perspectives from the areas of coastal sciences, economics, public policy, and land-use planning in creating a systematic plan for coastal management and protection. It has been more than a decade since New Jersey developed the nation's first state shore protection plan, and this volume provides a timely evaluation of its achievements and future challenges. This self-contained book provides all of the relevant theories, models, and examples so the reader will not need to refer to any other literature to gain an understanding of the issues and policies surrounding shore protection. It is the authoritative handbook for practitioners and policy makers in many fields, including coastal science and management and engineering, as well as public policy and economics.
After discussions with the U.S. Army Corps of Engineers, the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, and the Office of Naval Research, the National Research Council (NRC) convened a committee under the auspices of the Marine Board to examine present and anticipated national needs in coastal engineering research and education and assess the adequacy and effectiveness of existing institutions in meeting those needs.
Text on coastal engineering and oceanography covering theory and applications intended to mitigate shoreline erosion.
This book considers the effectiveness of insurance coverage for low-probability, high-consequence events such as natural disastersâ€"and how insurance programs can successfully be used with other policy tools, such as building codes and standards, to encourage effective loss reduction measures. The authors discuss the reasons for the dramatic increase in insured losses from natural disasters since 1989 and the concern that insurers have about their ability to provide coverage against more such events in the future. It addresses why there has been an increasing demand for hazards insurance, what types of coverage private insurers are willing to offer, and the role of reinsurance and private-/public-sector initiatives at the state and federal levels for providing protection to victims of natural disasters. Detailed case studies of the challenges facing Florida in the wake of Hurricane Andrew in 1992 and California following the Northridge earthquake in 1994 reveal the challenges facing the insurance industry as well as other concerned stakeholders. The National Flood Insurance Program illustrates how a public-/private-sector partnership can mitigate damages and provide financial protection to victims. The book identifies new initiatives for reducing future losses and providing funds for recovery through cooperation by the relevant parties.
