Abstract

No integrated municipal policy exists for managing the New York City waterfront. Despite much rhetoric and many proposals to renew the city's coast, the municipal government has done little to improve the city's coastal shoreline. External organizations and citizens’ groups have been largely responsible for efforts to improve the use of the city's coastal resources. This article assesses the role of the city government and analyzes the factors affecting its performance in coastal management. It proposes new policies to foster local initiatives and encourages private and public cooperation in the revitalization of the coast. Given the size and diversity of the city's coast, an incremental strategy may be the most feasible and sensible approach to recapture the city's lost waterfront.  相似文献

Coastal erosion is a serious problem that affects the safety and livelihoods of many coastal dwellers along Ghana's coast. Despite the fact that coastal erosion is a natural phenomenon, erosion trends have been largely aggravated by human-induced factors. This study analyzed shoreline change rates for three neighbouring coastal communities in the Central region of Ghana; Elmina, Cape Coast and Moree. Two epochs were analyzed, 1974–2012 (medium-term) and 2005–2012 (short-term), using ArcGIS and Digital Shoreline Analysis System. Overall, the entire study area recorded average shoreline change rates of ?1.24 myear?1 and ?0.85 myear?1 in the medium-term and short-term period respectively. Less consolidated shoreline segments recorded higher erosion rates in both periods while cliffs and rocky segments experienced very little erosion or high stability. Because shorelines undergoing chronic erosion do not fully recover after short-term erosion events such as storms, facilities located close to such shorelines are threatened. Taking a proactive approach to coastal erosion management, such as coastal sand mining prevention, inter-sectoral land use management and adopting a construction setback approach may be prudent for the long-term management of the coast since this recognizes future shoreline changes and safeguards coastal landscape for other uses.  相似文献

Abstract

It was pointed out in a recent article on shorelines management in France that no overall coastal management legislation in that country exists.1 Nevertheless, certain existing legislation has been adapted to take account of the peculiarities of the shoreline and coastal zone, and new institutions such as the “Shorelines Trust”; have been created.2 As is the case with most countries in the Western world, the processes of urbanization, industrialization, and recreational development place tremendous pressure on shoreline use. Resulting conflicts are sometimes difficult to solve unless adequate institutional frameworks exist. Some form of institutional change is thus inevitable.  相似文献

Abstract

Notions of private property have both legal and political importance. In California, as elsewhere in the United States, these ideas are changing. The rate and direction of this evolution is not different on the coast. But the intense heat generated by competing coastal interests does tend to illuminate these issues more clearly on the coast. The full range of these issues has been raised in California, where an historic attempt is now being made to plan and manage the use of coastal resources. In January 1976 the California Legislature will be presented with a coastal plan which promises to inflame the passions of traditional property rights advocates and environmental zealots alike. Much of the rhetoric surrounding this political struggle is already being couched in legal terms. In an effort to delineate a few of the genuine legal issues raised in this planning process, this article summarizes the law of California which is relevant in defining the permitted scope of public regulatory power over private land use.  相似文献

Abstract

One approach to the management of coastal and marine areas is the establishment of protected areas (e.g., reserves, parks, sanctuaries). Under the general rubric of “marine reserves,”; this paper examines the Latin American experience with this strategy. A comprehensive table lists most, if not all, national or state declared parks or reserves. The table is organized by country. All Latin American nations have, to a varying extent, declared marine parks and protected areas. The authors review the sources or uses which have been “managed”; by marine reserves, the management approaches, uses, and problem which have been identified in achieving management objectives. The authors conclude with observations about the potential future utility of marine reserves as a management approach for areas and resources of the coastal and littoral zones of Latin America.  相似文献

Abstract

Presently, much of Israel's 190‐kilometer‐long Mediterranean coast is either unoccupied, devoted to unsuitable uses, or is in use by activities which have no special need to be near the water's edge. This has resulted from years of lack of appreciation by policy‐makers of the coast as a valuable resource, of national development policies that directed attention to other regions, and of the relatively limited demand for coastal recreation.

In the last decade the importance of these factors has diminished. In turn, there is now mounting pressure for the development of coastal land. Increasingly, rising standards of living with a greater demand for recreational facilities, the growth of tourism as a major industry, and demands of the environmental lobby for conservation of part of the coastal land are factors bound to cause intensive change along the coast and to affect the quality of its resources. These trends have brought about public intervention in deciding the future of the coast. This paper reviews and analyzes Israel's coastal policy and its resource management programs, and also discusses the potential challenges to their full implementation.

Three types of programs were suggested as the main management tools: a coastal research and development effort, national coastal land use planning and pollution prevention, and monitoring and control programs. Major objectives of the programs were to be achieved through land use controls. Consequently, an important role is given in the development and implementation of the coastal program to agencies responsible for the management of physical land use planning and development.

Successful implementation of the management program, however, will depend on the ability of its administrators to coordinate the actions of many interests, on success in changing attitudes among decision‐makers as to the value of the coast, and on widening support for coastal resource conservation among a presently uninvolved public.  相似文献

Abstract

This article concerns optimizing the use of environmental information for creative planning. It arose from a detailed study of the status and management of the coastal dunes of New South Wales, Australia, and discusses the way in which ideas for optimizing the management process were developed, and applied to three beach environments on the coast of New South Wales, Australia.

The problem of coastal beach/dune management may be thought of as being similar to a production function in which the inputs are the land resource, the skills and knowledge of managers, finance, and materiel. The outcomes are in the form of experiences, or opportunities for experiences, either passive or active, either consumption values or option values, desired by the coastal user population (which includes the resource managers themselves). The resource manager's task is to manipulate the “production function”; in order that the outputs will best mesh with the expectations of the user population and with the capability of the land resource to deliver on a sustained basis. An aim of the project was to develop a method for the specification of different possible outputs from the production function, in different beach/dune environments, and that could be used to assist in the preparation of advice on appropriate recreational development, allowing decisions to be based on both environmental data and information on the expectations, activities, and amenity preferences of beach users.  相似文献

Abstract

Ports are often at the center of conflicts regarding the use of coastal areas and their management. Yet, it is often impossible to forecast the future development patterns of a port due to its dependence on shifting international relations and markets. Such inherent uncertainty complicates the management of coastal areas affected by the port. This article looks at how such a case is being addressed in Eilat, Israel's Red Sea port.

The development of Eilat's port has been a function of the changing geopolitical situation in the Middle East. At the same time it is in the center of a number of local conflicts involving the management and planning of Israel's Red Sea coast. Evaluation of the two alternatives proposed to address these conflicts is hampered by the inherent uncertainty regarding the port's growth patterns. The use of robust evaluation techniques is suggested as one way to address inherent uncertainties.  相似文献

Abstract

South Carolina has a significant stock of diked coastal wetlands, dating from the days of rice culture before the Civil War. A survey of those controlling these sites along the entire South Carolina coast reveals that many continue to be used for waterfowl hunting, with management practices becoming more intensive than they were when partial data were gathered a decade ago. It also suggests that most of the acreage involved is located in large fields, where management is more difficult and mosquito control problems are more likely. This survey also indicates that public access is limited, but that there is evidence of continuing conflict over ownership. This situation creates a persisting dilemma for coastal zone management, shaping conflicts between alternative strategies for the use of natural systems.  相似文献

Abstract

Major challenges are ahead in managing the coastal zone of western Canada. Until now there has been no legislated focus through a coastal zone management act nor a policy for the management of coastal resources. Instead, policies and institutions have been evolving out of existing legislation responding to opportunities and needs as they have arisen. Management is predominantly a bargaining process the success of which depends on opportunities for informed participation by the affected interests. Considering the relatively small investments in management, bargaining appears to have worked rather well, but there are weaknesses. Fortunately, significant opportunities exist to improve performance at relatively low cost. In particular, there should be a shift from the past emphasis on inventorying, monitoring, and coordination, to the development of functional knowledge and sectoral planning that can be the basis for informed and representative bargaining.  相似文献

Abstract

Offshore hydrocarbon exploration has been undertaken on Canada's Atlantic continental shelf since 1964. It is only recently, however, that the Hibernia find off the coast of Newfoundland has raised the possibility of the eventual production of oil. This article reviews the history of offshore exploration, comments on the locational significance of the Hibernia field, and analyzes the implications of the Newfoundland government's policies for affecting the location of onshore support facilities. A critique of these policies is placed within the context of coastal zone management and planning.  相似文献

Abstract

This introductory piece traces the growth of knowledge and activity associated with visual resource management in general. A specific framework of questions regarding methods of coastal zone visual resource management is presented. The state‐of‐the‐art in methodological studies is listed for each question, and the methodological questions are related to the major articles with the special issue of the Coastal Zone Management Journal. Major legal federal statutes, state statutes, and court cases are reviewed in light of visual resource management in the coastal zone. The remaining articles within the special issue that deal with integration of VRM into decision‐making are then arrayed against a management framework. This framework includes regulatory situations for (1) public land management and planning, (2) public projects involving private lands, and (3) public regulation of private projects.  相似文献

Abstract

Coastal zone management in Oregon is based on the state's general land‐use law. This body of law is designed to deal with population increase, urbanization, and preservation of agricultural land, as well as with other problems throughout the state. Early planning and policy recommendations for the coast were in the hands of a commission having predominantly local membership. This commission produced an extensive series of studies, policies, and recommendations which were assembled as a proposed management tool for natural resources. Staff of the commission was then absorbed into the state land‐management agency, which developed final goals and guidelines for compliance with the Coastal Zone Management Act. Adoption of the coastal goals in December 1976 has triggered deadlines for local government compliance within the coastal zone. The management program is now undergoing federal review.  相似文献

Abstract

The basis for coastal zone management in the United States is established in legislation. In comparison, Canadian federal and provincial governments have adopted a piecemeal approach for managing a variety of concerns examined here: water quality, ecological protection, public access, aesthetics, natural hazards, and water dependency. As a result of this approach, which is characterized by a minimum of federal, provincial, and interjurisdictional coordination, the British Columbia coastal zone is showing signs of stress. For example, major shellfish harvesting areas are being lost to water pollution; ecologically sensitive habitats are being consumed by urban, commercial, and industrial expansion; recreation and tourism opportunities are being impaired by clear cutting and other inappropriate developments; and infrastructure is allowed in flood and erosion‐prone areas. Recommendations to improve the approach to coastal management in British Columbia include a variety of innovations. New federal and provincial policies, legislation, institutions, and experimentation with local and regional integrated resource planning are required to better govern the coastal zone. Increased support for existing agencies, public involvement, and access to information as well as more common use of environmental impact studies are needed to justify proposed coastal developments.  相似文献

Abstract

This article argues that using the public sector and the private market in the historically delineated and traditional ways offers only the bluntest of tools with which to approach the complex problem of coastal zone management. It therefore seeks to provide a basis for reformulating our understanding of sectoral responsibility with regard to resources management. First, it conceptually analyzes the relative strengths and weaknesses of the two sectors. Second, it examines three examples of coastal resources management—beaches and shorelands, artificial reefs, and coastal wetlands—in analyzing the complexities of the coastal management challenge and the limitations of our current approaches. Finally, we provide an alternative perspective on how these common property resource allocation decisions can be made.  相似文献

Abstract

This paper reports on research conducted in support of a coastal zone management effort to reduce erosion and sedimentation impacts in a wetland watershed, Elkhorn Slough, Monterey County, California. The research reviews methods of determining soil erosion susceptibility and relating it to land‐use intensity within the watershed, measured by a land disturbance index. Erosion susceptibility is measured in three ways: by a combination of slope and the erosion factor of the Universal Soil Loss Equation; by field measurement of erosion and deposition on selected sites; and by computer‐assisted terrain analysis of data from secondary sources. Land use is shown to be a more important factor than landform in influencing relative erosion susceptibility.  相似文献

Abstract

Artificial reef development involves pfonning from a number of perspectives including biological, océanographie, engineering, and social. This article reviews previous studies and identifies demographic variables that affect the use of artificial reefs by recreational anglers. An index of relative demand was created employing eight components: number of coastal county resident boat anglers, nonresident boat anglers, tourist boat anglers, nonboat anglers, number of fishing clubs, number of charter/party boats, number of registered pleasure boats, and the rate of county population growth. By comparing the magnitude of the index to the number of existing artificial reefs off of Florida's 35 coastal counties, an estimate of relative need was graphically portrayed on a state map. Indian River county on the Atlantic coast and Hernando, Hillsborough, Pasco, Citrus, Levy, Lee, and Charlotte counties on the central Gulf coast are the areas with the greatest demand relative to existing reef supply.  相似文献

Abstract

This model statute sets out a mechanism for the management of the coastal zone by the coastal states. It provides a possible state response to the Coastal Zone Management Act of 1972. The authors recognize that most states presently have some form of management or legal control over their coastal zone, and the model statute has been written with the intention that all or parts of it could be adapted to the wide variety of state regulatory schemes with the aim of providing unitary management to the valuable resource of the coastal zone.  相似文献

Beach erosion can have important socioeconomic and environmental consequences, particularly in tropical regions where tourism is a significant source of income. Although caused by natural processes, erosion is often aggravated by disorderly anthropogenic modification of the coast and extreme events. In Yucatan, Mexico, increasing urban development and deficient coastal management strategies as well as hurricanes have affected beach stability. This has highlighted the need for adequate coastal planning and policies that ensure the protection of key coastal ecosystems, such as beaches and sand dunes. To address this, a methodology to classify the coast according to its vulnerability is presented in this work. This methodology assumes that morphological features are indicators of beach evolution and the processes driving it and that these can be associated with different levels of vulnerability. The features considered are beach width, dune vegetation, anthropogenic pressure, and shoreline orientation, which were analyzed through aerial images and a multicriteria evaluation. It was observed that the most vulnerable areas are found near the most developed parts of the coast, where narrow beaches with little dune vegetation dominate. It is expected that this index will be of use to coastal planners and decision makers, particularly in the identification of critical zones.  相似文献
