Abstract

The physical characteristics of Korea have had a profound impact on the uses of the coastal zone that have, in turn, been determined by and reinforced the nation's economic development strategy. While coastal zone management in many developed economies is more heavily oriented toward environmental protection and the resolution of user conflicts, policies for coastal zone management in Korea have emphasized the role of coastal space and other resources for economic development and industrial needs. Increasing demand for land reclamation to provide ever‐increasing industrial sites and human settlements, traditional and future needs of the fishery, and concern for the environment have led to a vast array of competition and, finally, often to conflicts. The basic pattern of coastal zone use in Korea has changed from the linear expansion of coastal zone to integrated coastal uses. An increased number of critical coastal zone issues and interactions was reflected in the creation of new governance that dealt with coastal zone resources and environment.  相似文献

Abstract

In a public opinion survey conducted in Santa Barbara county, California, respondents were interviewed regarding their feelings on coastal zone development, within a context of broader environmental and political issues.

A high degree of expressed concern for the environment was found, but the data also indicate a widespread reluctance to allocate a greater share of personal income to improve environmental quality.

Among the issues dealt with are citizen views on environmental problems, the effectiveness of government in the environmental field, offshore oil drilling, and coastal zone development.

The results show that on each of the issues analyzed, a person's education, age, and the extent of his political participation are the major factors which determine his concern for the environment. Additional variables appear to have some significance in determining attitudes toward local environmental projects and perceptions of government.

Offered are implications of the findings for the future of organized action on environmental problems.  相似文献

Integrated coastal management has been seen as the way to deal with the challenges currently facing managers of our coastal zones. In the tropics, these areas are typified with resources such as coral reefs and mangroves that are able to support a variety of activities. Integrated coastal management takes a multi-disciplinary approach that involves the integration of the different institutions and stakeholder groups in the coastal zone. A survey of tropical coastal locations revealed that fully implemented integrated coastal management is limited with programs apparently failing at the implementation stage. These coastal zones share a number of common challenges exacerbated by poverty and conflicts between the coastal activities. Conflict management needs to be incorporated into the management process that pays particular attention to the overextraction of resources and destructive resource use.  相似文献

A mail survey of coastal user groups, academics, and state coastal zone management program managers was conducted to determine the perceptions of the performance of state coastal zone management programs relative to the protection of coastal resources, the management of coastal development, the improvement of public access, and the management of coastal hazards. Information on the perceived importance of the selected issues to each of the 24 states being studied was also solicited. Findings on the perceptions of various categories of interest groups, academics, and program managers with respect to the overall performance of state coastal zone management programs in the four issue areas were presented in an earlier article, “Perceptions of the Performance of State Coastal Zone Management Programs in the United States”; (Knecht et al., 1996). The present article draws on a subset of these data—the responses from the coastal user groups and the academics—and presents the findings at the regional and individual state level. In terms of perceived performance of state coastal zone management programs on a regional basis relative to the selected issue areas, the highest rating went to the Great Lakes region for its management of public access. However, the North Atlantic region received the highest performance rating for the three other issue areas: protection of coastal resources, management of coastal development, and management of coastal hazards. Looking at state performance with regard to the coastal issues judged to be of most importance to the states—the protection of coastal resources and the management of coastal development—respondents indicated that states should improve their performance in both areas, with the greatest need related to the management of coastal development. Overall, the states of the North Atlantic, Great Lakes, and South Atlantic regions were perceived to be performing somewhat better relative to the four issue areas than the states in the Pacific and Gulf of Mexico regions. While the data do not shed light on the reasons for these regional differences, we suggest that, in the case of the Pacific region at least, the differences could be associated with higher expectations among the resident population with regard to environmental quality in general and coastal management in particular.  相似文献

Abstract

The location as well as pace of marina development is a major issue in current coastal zone management. The supply and demand for marinas providing certain services in specific locations are growing and must be met. At the same time the environmental integrity of the coastal zone must be maintained against the many possible impacts of marina development. Compounding these problems from the view of both the developer and coastal zone manager is the absence of necessary data and accepted methodologies for estimating future supply needs for marine berthing. This paper describes a multi‐focii approach to the establishment of an information base and marina supply projections for the Mississippi Gulf Coast. Data on existing marina types, services, and facilities are obtained via fieldwork; future marina slip supply needs are estimated using a combination of several techniques and data sources. The study serves two purposes. First, it initiates the basis for improved management of marina development on Mississippi's Gulf Coast. Second, on a more theoretical level, it stimulates research toward developing and validating supply and demand projection techniques for marinas.  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

In this article, an overview of the status of coastal zone management (CZM) in South Africa is presented. Firstly, it provides background to the development of various initiatives to promote sustainable use of coastal resources within the context of sociopolitical changes in South Africa. Thereafter, it examines the progress made with respect to key attributes underpinning most CZM programs. Finally, it identifies obstacles to achieving effective CZM in South Africa and makes recommendations to address these shortcomings. The review reveals that whilst considerable progress has been made in certain areas of program development, such as resource conservation and pollution control, there are several gaps and inadequacies within existing efforts. These include the absence of a clear policy to guide efforts, lack of coordination amongst government departments involved in CZM, as well as inadequacies in our legal and administrative system. The promulgation of a Coastal Zone Management Act and the establishment of a Coastal Unit charged with the coordination and review of all activities impinging on coastal resources are amongst the recommendations made.  相似文献

Recent emphasis in comprehensive planning for coastal zone regions has created the need for more effective tools for information processing and analysis to aid policymakers and planners in developing strategies for preservation of coastal zone areas. New agencies with broad powers have been created at both state and federal levels to deal with growth management in large coastal regions. However, coastal zone management (CZM) agencies have not yet been able to deal effectively with development processes. A “holding action”; is being maintained in the face of mounting pressure by developers, while planners struggle to develop (1) a data base with sufficient detail for planning; (2) a fair and rapid process for reviewing environmental impact statements and granting of development permits; and (3) a system for making the development permit application process more routine. The key to success of the CZM process is the development of a management information system (MIS) created explicitly for CZM. The prototypical system designed by the authors combines graphic display capabilities (i.e., map display) with interactive on‐line computing and large storage‐capacity computers. Problems of data structure development are documented, together with problems of assembling a large‐scale, highly detailed data base. Of particular importance is the need for well‐developed objectives and specifications for the use of computer‐based data in resolving disputes on environmental issues. A set of objectives and specifications for a prototypical coastal zone MIS is developed. The system is described in detail, showing how its capabilities directly address policy questions formulated by coastal zone planners.  相似文献

Australia's coastal environments are exposed to great pressures. Adequate policy and management measures are required to ensure the protection of coastal assets now and for future generational use. However, recent government reports and academic literature have highlighted that improved science uptake into policy is needed to ensure coastal communities are protected from impacts such as climate change. The literature suggests that individuals, coined champions, can play an important role in influencing the use of science by policymakers. However, a paucity of research exists surrounding the role of these individuals. This research explores the role of champions in enabling science uptake into policy in the Australian coastal zone, investigating champion characteristics and strategies used in influencing policymakers. A mixed-methods approach to the research was employed, integrating a paper/online survey of people involved in Australian coastal management and in-depth, semi-structured interviews with champions nominated by their peers from the survey. Fourteen key coastal champion characteristics were identified from the survey. Furthermore, the champion interviews identified strategies for influencing science use by policymakers. From these findings a conceptual model was created. In order to enable coastal champions to be fostered, a six-step process was developed that incorporates the use of the conceptual model.  相似文献
