Abstract

The National Park Service is required by law to conserve nationally significant resources for public benefit. Susceptibility to local short‐term economic pressures and a lack of understanding of resource dynamics can jeopardize mandate compliance. Assateague National Seashore is an example of a dynamic barrier island where early understanding of ecologic factors should have preceded its establishment and must precede its management and development. Research conducted on a similar system has demonstrated the dramatic environmental impacts and high maintenance costs associated with an inappropriate recreation management scheme. Alternatives are available which minimize resource degradation and maintenance costs without restricting visitation. To better ensure incorporation of long‐run ecologic and economic criteria into the decision‐making process, a proposal is put forward which recognizes the need for an expanded research effort and close adherence to early planning steps.  相似文献

Abstract

Growth in the number of cottager, or lake property owner, associations in Ontario has been rapid. Cottager associations attempt to address directly, and influence government decision‐making on, issues affecting shoreline management and the recreational experience of cottagers. However, associations infrequently resolve these issues to their satisfaction. A questionnaire and case study show that the nature of the issue, human and financial resources available to the association, and the nature of the decision‐making process affect the extent to which associations influence outcomes. Unreceptiveness of government officials to association participation in decision‐making and confused agency jurisdictions over shoreline resources appear to inhibit association effectiveness. Concerns about the status of shoreline management in Ontario and public participation in decision‐making are raised.  相似文献

Abstract

Urban coastal management is now part of a large, complex set of regional, state, and federal interorganizational arrangements. This emerging matrix consists of a loosely linked set of nearly independent decision points. Cities have little capacity within this matrix for independent action. Recent experience in the SOHIO project by the City and Port of Long Beach, California, illustrates the point to which external agencies have taken over decision‐making for use of coastal resources. Public bodies removed from city affairs and politics and with interests in other than coastal affairs have become dominant and have overridden local policy‐making. The public costs to citizens and local governments of the emerging interorganizational matrix are very high and may be excessive. As it is emerging, the matrix is a semi‐autonomous set of bureaucratic decision points which is unhinged from community values and regular political infrastructures.  相似文献

Abstract

Abstract This case study, prepared by an interdisciplinary group of several scientists and planners and a lawyer, reviews the handling by the decision process of an application to the Baltimore District Corps of Engineers for permission to construct a marina. The study determines that while the project in question may not present a significant environmental threat, the project when considered in conjunction with other pending projects on the same subtributary would contribute to boat congestion and degradation of water quality. Changes in the decision process are suggested which would facilitate consideration of the cumulative impacts from a series of coastal alterations.  相似文献

Abstract

Competent administration of the Coastal Zone Management Act of 1972 (CZMA) must proceed on an informed understanding of the organization styles and capacities of agencies presently dealing with similar problems. One such agency, the San Francisco Bay Conservation and Development Commission (BCDC), the forerunner of the California model of coastal management, is analyzed here to shed light on where we are headed and what we can expect administratively as the CZMA becomes an operation reality.

The major administrative insights offered fall into the areas of: (1) effectiveness assessment‐the BCDC's success is systematically defined and measured, and a discussion of what effectiveness evaluation implies in the area of coastal resource management is undertaken; (2) understanding organizational success—the BCDC's administrative style is analyzed in terms of the synergy which has been created between its organizational structure and decision‐making process; and (3) implications of agency success—which of the BCDC's lessons are most valuable and how these can be applied to other situations are shown.  相似文献

Abstract

Designing environmental monitoring programs to deal with widespread, subtle, and/or cumulative impacts on a regional basis is challenging. It requires a shift away from focusing primarily on individual point sources to a more regional perspective. It also necessitates involving scientists and managers together in a cooperative effort to establish priorities and articulate clear objectives. In our view, this objective‐setting task is neither a strictly scientific nor a strictly management activity. It depends on effective communication between scientists and managers but is confounded by differing perspectives, value systems, and behaviors. We present a conceptual framework to assist managers and scientists in this process. This is intended to structure such communication by helping to create a context that permits fruitful give‐and‐take between the two groups. We then describe a six‐part model for specifying the key elements of regional monitoring objectives.  相似文献

Abstract

The United States currently has a 3‐mile territorial sea limit which is under the jurisdiction of coastal states. In the event the United States joins with other countries in adopting a 12‐mile territorial sea, Congress may consider extending state jurisdiction to 12 miles. It may be in the best interest of coastal states to oppose extension and instead support a strengthened federal‐state ocean management regime which disregards boundary lines and is based on the sharing of outer continental shelf leasing revenues along with a guaranteed role for coastal states in federal decision‐making.  相似文献

Abstract

The first comprehensive attempt at development control along the Canadian Great Lakes shoreline was the 1976 lakeshore regulation policy adopted by the Regional Municipality of Haldimand‐Norfolk on the north Lake Erie shore. This innovative strategy was initiated at the municipal level as a component of the regional land‐use planning process. Determination of efficiency and effectiveness of the policy implementation process is based on analysis of permit approval files. All development applications submitted between 1976 and 1980 in the Turkey Point and Long Point Peninsulas are evaluated. Those areas, the most popular cottaging areas in the region, are most susceptible to flood and erosion hazards. Of the total applications submitted during the four‐year study period, 37 percent were in these areas. The policy was ineffective and inefficient in controlling development in the two peninsulas. Applications were approved in the majority of cases, despite regulatory prohibition of developments in hazard‐susceptible areas. There were lengthy decision‐making delays, often exceeding one year, and frequent violations of regulatory procedures. Recommendations are suggested to improve policy implementation.  相似文献

Abstract

Recent land use legislation pays particular attention to the coastal zone where age‐old conflicts have recently accelerated. Flexibility is required in policy because visible conflicts are tied into complex physical and social systems which may require changing patterns of land use over time. Public policy is altering property rights and a thorough understanding of the economic and social roles played by those rights is required. Economic models can be used to understand some major changes such as types of alteration of the environment, but may be ignored or misused unless a better understanding of coastal decision processes is developed.  相似文献

ABSTRACT

Shipping is characterized by extreme changes in revenues, operating expenses and asset values, making shipping banks’ final decision for financing shipping market considerably harder. This paper develops a practical decision tool based on the estimation of the credibility factor in the decision-making process, each bank’s policy, and the most significant variables arising from both its operating environment and the dry bulk market. Revealed relationships between bank’s internal environment, its own policy, and dry-bulk shipping market conditions through GDP growth of China constitute a newly presented decision framework in shipping finance. The values of credibility factor implicate either an aggressive or passive defensive strategy taking into account the GDP China changes: Consistent with the economic growth of China, a bank’s holds an aggressive policy if the credibility coefficient is about one. On the other hand, the model predicts that a less aggressive policy in combination with the increase of China’s GDP would drive to the decrease of bank’s loan grants.  相似文献

Abstract

This article suggests a method of estimating economic losses for estuary‐dependent faunal species under conditions whereby the impact of a given degrading development on a particular estuary has a significant degree of uncertainty associated with it. The approach draws on standard theories from a variety of disciplines to provide an operational procedure capable of joint application by biologists, economists, and other related disciplines with working responsibility in the subject area. Consideration is given to probability estimation of possible impacts, sensitivity to underlying assumptions, and decisional safety under conditions of uncertainty. Applied results are demonstrated in a simulation of a negative developmental impact on the estuary‐dependent salmon resources of the Fraser River in British Columbia.  相似文献

Abstract

Risk assessment is a methodology which has been used to evaluate the safety of major public projects, notably aerospace programs, liquefied natural gas import facilities, and nuclear power plants.

This article begins with a review of public attitudes toward risk and then describes the basic components of a risk assessment. Subsequent critical analysis suggests the pitfalls inherent in the technique, especially in regard to the establishing of a criterion of safety against which the results of a risk assessment will be compared. The author identifies three such criteria and rejects two of them, including the one most commonly used in federal government agency decision‐making, as unreliable or philosophically unacceptable.

The article concludes with comments on the applicability of risk assessment in coastal zone management.  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

The Virginia Wetlands Act of 1972 provides the localities of Tidewater Virginia an opportunity to participate in the management of the state's coastal wetlands resources. This study attempts to analyze the effectiveness of this legislation and to examine the implications of a local management scheme for coastal resource management on a broader scale. Criteria are also established that can be used to evaluate the effectiveness of such a law. When examined in the light of these criteria, the Virginia Wetlands Act emerges, for the most part, as an effective piece of environmental quality legislation that has had a significant impact on wetlands destruction in the state of Virginia. During the two‐year period following the passage of the Act, wetlands losses through the permitting process showed an 18‐fold decrease from previous estimates. The Wetlands Act appears to have been generally accepted by the public and has resulted in consistently uniform decisions, which have reduced wetlands losses without unduly restricting the necessary and legitimate development of the state's wetlands.  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

An estuarine sanctuary is a store of public values due to the ecological, cultural, recreational, aesthetic, historic, and economic services provided by the preserve. These values may be expected to increase over time because of (1) growth in the population demanding estuarine services, (2) growth in the willingness to pay for such services, and (3) growth in the actual quality and quantity of services which are provided by a protected natural system. Thus an estuarine sanctuary will be more valuable to future generations than to current generations. When weighing the cost and benefits of a preservation or development decision, a preservation decision which seems currently undesirable may in fact be socially beneficial when growth in the value of estuarine services is included.  相似文献

Abstract

The use of environmental impact assessment (EIA) is relatively recent in the People's Republic of China (PRC). China is committed to a reversal of the environmental degradation resulting from its industrialization and the central government has initiated a requirement for environmental planning and assessment for large development projects. Today large scale harbor developments are subject to the requirements of the National Environmental Protection Law (1979) and the Marine Environmental Law (1982). Because the third phase expansion of the coal port of Qinhuangdao would increase the ports’ capacity to handle coal by 30 to 50 million tons, an EIA was required.

Since 1981, the Environment and Policy Institute of the East‐West Center (EWC), Honolulu, has had a program of research focusing on the environmental impacts of coal transportation. On the basis of workshops in China that centered on the problems associated with planning coal transportation projects, the Ministry of Communications of the PRC invited the EWC to participate in the environmental assessment for the third phase coal port expansion at Qinhuangdao. A 10‐member team with specialities in environmental assessment and port environmental problems from five countries representing the EWC worked with a 25‐member team from four different agencies of the PRC Ministry of Communications.

This article describes the environmental regulations in the PRC that affect this harbor expansion, discusses the process by which the EWC assisted the PRC in the preparation of the environmental assessment and evaluates the assessment product against PRC regulations and U.S. standards. The most important contribution of the EWC was the provision of guidelines adapted from the EIA experience in several countries which will assist the PRC in the environmental evaluation of future pon expansion projects.  相似文献

ABSTRACT

Berth planning plays an important role in improving the efficiency of a container terminal. This study focuses on the berth template problem (BTP), which determines the berthing windows of the calling ships within a planning horizon (e.g. a week) in a cyclical way. As a mid-term tactical decision problem, BTP provides the decision support for a terminal operator to negotiate the contracts with the shipping lines. This study develops an integer programming (IP) model aiming to minimize the total deviation, given the ship-dependent target times preferred by the shipping lines. To validate the model and illustrate the benefits of its use, we perform a numerical experiment based on operational data of a specific container terminal in Southeast Asia. Two IP-based heuristic methods are developed to take into account the decision framework of terminal operators in reaction to demand increases. The experiment results indicate that the model and the solution approaches can enhance the resource utilization and operational efficiency of container terminals.  相似文献

Abstract

Seaport expansion often generates tensions between the national interest in efficient transport and local interests in water quality and habitat preservation. The governing American permitting system, however, establishes an extraordinarily cumbersome, legalistic, and costly method for balancing environmental and economic considerations. A case study of the Port of Oakland illustrates the tendency. For four years, plans to find an environmentally acceptable site for dredged material have been stymied by a sequence of inconclusive regulatory and judicial proceedings. Meanwhile, large container ships can enter and leave Oakland harbor only at high tide, and not fully loaded. Despite the absence of any authoritative determination concerning environmental risks, the port was compelled to accede to progressively more expensive disposal methods. Such “adversarial legalism”; is not unique to the Oakland harbor case, but recurs in other policy spheres. It stems from a governmental structure that fragments decision‐making power among many agencies, that constrains regulatory discretion with legal demands for scientific certainty, and that by allowing agency decisions to be challenged readily in court, encourages legalistic defensiveness and extortion rather than compromise. The article concludes with a discussion of the conditions under which regional planning bodies might overcome these centrifugal tendencies.  相似文献
