Abstract

Natural resource management entities such as the Regional Fishery Management Councils established by the Magnuson Fishery Conservation and Management Act of 1976 depend heavily on science to inform policymakers and to legitimate the policy process. This paper discusses the importance of fishery science to the council system, contrasts the functions of Scientific and Statistical Committees (SSCs) serving the Pacific Fishery Management Council and the New England Fishery Management Council, and remarks on the implications of differences in the display of scientific authority by these SSCs.  相似文献

The U.K. government is committed to establishing a coherent network of marine protected areas by 2012 and the recent Marine and Coastal Access Act, 2009 will designate marine conservation zones and provide wider access rights to the coast. To fulfill these goals, this article argues the need for a clearer, shared understanding of the social value of protected areas in creating new designations and managing existing ones. Although marine and coastal environments attract many people and are vitally important in terms of realized and potential social value, the majority of the public in the United Kingdom lacks understanding and awareness regarding them. Combined with this, the social value of marine and coastal protected areas (MCPAs) have been largely ignored relative to conservation and economics, with the latter invariably taking precedence in environmental policymaking. Social value reflects the complex, individual responses that people experience in a given place. Many reasons determine why one area is valued above another, and this research investigates the social value of MCPAs from a practitioner's perspective through a series of interviews. Understanding why we “socially” value MCPAs will ultimately equip managers with an informed understanding of these spaces, influence management decisions, and, potentially, policymaking. This article defines social value in the context of MCPAs in England and Wales from a practitioner perspective, explores key concepts, and suggests possible improvements in decision-making.  相似文献

Abstract

This paper concerns the limitations on integrating visual management into the coastal zone planning process as exemplified by the Commonwealth of Massachusetts, a state with a strong tradition of “home rule”; and a CZM implementation program based on a “networking”; of existing state authorities. The implications of the Massachusetts experience are that: (a) management of esthetic resources at the state level continues to be much less of a priority than management of ecological resources such as wetlands or floodplains; (b) visual management has yet to engender a strongly supportive constituency beyond that concerned with historic preservation; (c) project review focusing on visual impacts may be a more appropriate activity for local rather than state government; and (d) the technical aspects of visual management or impact assessment are far more advanced than their political acceptability. Political realities, together with the decision that implementation of the program should be based on a networking of existing authorities, thus determined the degree to which visual management could be incorporated into the state's program. As a result, the program's principal instruments of visual management became a strengthening of existing programs such as Wild and Scenic Rivers, reliance on wetland protection statutes to indirectly protect natural scenic values, and the use of the federal consistency provisions of the Coastal Zone Management Act to foster focused growth patterns through provision of publicly funded infrastructures. Esthetically oriented project review, with the exception of potential impacts on historic sites, was left to the discretion of local government, and a technical assistance program was created to provide funding or professional skills to communities interested in developing their own esthetic controls or design review processes. Maine, Rhode Island, and other New England states have followed a similar course.  相似文献

This study estimates and analyzes the transaction costs (TC) associated with the implementation of a multilevel and multistakeholder program such as a community-based coastal resource management program. Results show that TC accounted for 37% of the total project cost (TPC). The instability of financial support resulted in high TC, which was estimated to be 86% of the TPC during the implementation phase of the coastal resource management projects. The share of the total TC was highest among the people's organizations (POs) that were the beneficiaries of the program. The number of people involved in the transactions, the number of activities undertaken, and the success index of the POs were among the factors significantly affecting the TC. Analysis also shows that while higher TC led to higher success index of the POs at the initial stage of the project implementation, an increasing level of TC eventually slowed down their performance.  相似文献

Recent estimates by J. Gosselink, E. Odum, and R. Pope of the economic value of natural wetlands have had considerable impact on analyses and discussions of public policies concerning natural wetlands management. However, these economic value estimates are neither conceptually nor empirically correct. First, these workers failed to recognize the nature of the process by which economic values are determined and made an illegitimate marriage of the principles of systems ecology and economic theory. Second, where Gosselink et al. attempted to apply proper economic principles, their calculations resulted in economic value estimates that are most likely in error.  相似文献

Coastal communities, indigenous peoples, and small-scale fishers rely on the ocean for livelihoods, for subsistence, for wellbeing and for cultural continuity. Thus, understanding the human dimensions of the world’s peopled seas and coasts is fundamental to evidence-based decision-making across marine policy realms, including marine conservation, marine spatial planning, fisheries management, the blue economy and climate adaptation. This perspective article contends that the marine social sciences must inform the pursuit of sustainable oceans. To this end, the article introduces this burgeoning field and briefly reviews the insights that social science can offer to guide ocean and coastal policy and management. The upcoming United Nations Decade of Ocean Science for Sustainable Development (2021–2030) provides a tremendous opportunity to build on the current interest, need for and momentum in the marine social sciences. We will be missing the boat if the marine social sciences do not form an integral and substantial part of the mandate and investments of this global ocean science for sustainability initiative.  相似文献

Quantifying progress in management of marine protected areas (MPAs) is crucial to marine conservation and fisheries management in the Philippines. This study compiles data on the status, occurrence, and management gaps of MPAs through coordination with multiple organizations supporting and guiding MPAs in the Philippines. MPA management effectiveness was measured using a MPA Rating System. Since 2002 the modal MPA rating levels increased from level 1 (initiated) to level 4 (sustained) in 2008/9. This upward trend is attributed to factors that promoted both the establishment and improved management of MPAs. Analysis indicated that: (1) most MPAs struggle with budgetary constraints or lack of sustainable financing and (2) overall the MPAs are being maintained and progressing with notable improvement in management despite a range of difficulties encountered during the implementation process. For MPAs in the Visayan Region for which biophysical data were available, the MPA Rating System was used to assess the effectiveness of local government capacity building on MPA coral reef health. Our results suggest that MPAs with higher ratings are likely to have better reef health conditions.  相似文献

In 2001 China embarked on an ambitious program to improve water quality through creation of the Clean Bohai Sea Program (CBSP). It is the first regional ocean governance program in China. The joint conference of central and local government units directed CBSP under the leadership of the State Environment Protection Administration. To meet the environmental objectives established by the joint conference local governments must pay for the program and operate it, but to date they have not been able to fully fund the effort. Although data indicate a decline of polluted discharges to the Bohai, one tabulation shows that the area of the sea that is polluted has increased each year from 2001 to 2005. Future enhancement of CBSP depends on revising incentives to better link local environmental programs and development, establishing funding mechanisms to equitably spread costs throughout watersheds, and creating comprehensive monitoring programs to better appraise program results.  相似文献

This article examines salt‐water aquaculture (mariculture) legislation in California, Florida, and Maine, as illustrative of one generic response of the law to aquacultural innovation. Unlike aquacultural legislation in other states, generally drafted to restrict leasing of coastal waters for specific existing technologies, the legislation studied represents a more flexible approach which would accommodate new technologies. Analysis of specific provisions of the three laws indicates the complexity of the issues involved and a variety of mechanisms selected for regulating mariculture, and identifies different state priorities and goals. This report concludes that whereas broadly drafted legislation exemplified by the statutes under study is more likely to accommodate new mariculture technologies than piecemeal legislation, there are a number of complex issues that must be identified and resolved in order to achieve the desired results. The failure of each of the states to respond fully to the broad range of issues involved may inhibit aquacultural innovation or unduly restrict nonaquacultural uses of the coastal zone.  相似文献

The Magnuson-Stevens Fishery Management and Conservation Act, enacted in 1974, is the primary federal fishery management legislation in the United States. The political impetus that led to enactment was the extensive foreign fish off U.S. shores that expanded following World War II and the failure of international negotiations to prevent the decline in many fisheries relied upon by domestic fishers. In Congress, there was uncertainty as to whether a comprehensive management program would be created along with a unilateral extension of fishery management jurisdiction out to 200 nautical miles. The delay in agreement over a new United Nations Law of the Sea Treaty and resolution of the extent of coastal nation jurisdiction over fisheries culminated in enactment of the legislation sponsored by Senator Warren Magnuson, a Democrat from Washington State, and Senator Ted Stevens, a Republican from the State of Alaska.  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

Abstract

Western Australia is fortunate that there have been few natural disasters on the coast. However, low levels of coastal erosion during the 1970s demonstrated the need to establish coastal zone management in that state of Australia. The erosion was quickly contained because private ownership to the high water mark is almost nonexistent, private property being set back behind coastal reserves along most of the coast. The provision of coastal reserves has been part of a deliberate nonstatutory coastal planning and management approach. As a result Western Australia has been able to use existing acts, coordination between existing government agencies, and coastal policies rather than enact specific coastal legislation to manage the coast.  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

This special issue provides insight into global conservation science by analyzing a 5-year, $12.5 million global marine conservation science and policy program that included over 50 studies in four priority regions involving over 100 scientists and numerous partners. In doing so, it provides reflections on critical challenges for any conservation science program that is intended to inform policymaking, including how to (1) ensure that science process and products influence conservation actions, (2) build global learning from a network of site-based projects, (3) strengthen in-region capacity, and (4) manage relationships across scales among scientists, conservationists, headquarters, and field-based staff. Information is presented on the development and progress of the program as a whole in addition to specific articles covering each of four focal geographic areas: Belize, Brazil, the Eastern Tropical Pacific Seascape, and Fiji.  相似文献

Abstract

The U.S. National Marine Sanctuary Program was established in 1972 by Title III of the Marine Protection, Research, and Sanctuaries Act (16 U.S.C. §1431 et seq.). In this article, we discuss the development of the sanctuary concept, and the original intent of Congress, and analyze how it was applied by the sanctuary program. Differences in interpretation of the program's purpose are examined, including discussion of the multiple‐use management concept, an important but controversial management technique used in the sanctuaries. The continuing efforts by Congress and the National Oceanic and Atmospheric Administration to clarify the program's purpose are investigated. The program's administrative history is explained and the current sanctuaries and active candidates are briefly described. In light of the 1988 reauthorization of the Marine Sanctuary Act, the current issues facing the program are analyzed. Finally, we draw conclusions and make recommendations for the program's future.  相似文献

Wind power resources on the eastern U.S. continental shelf are estimated to be over 400 GW, several times the electricity used by U.S. eastern coastal states. The first U.S. developer proposes to build 130 large (40 story tall) wind turbines in Nantucket Sound, just outside Massachusetts state waters. These would provide 420 MW at market prices, enough electricity for most of Cape Cod. The project is opposed by a vigorous and well-financed coalition. Polling shows local public opinion on the project almost equally divided. This article draws on semistructured interviews with residents of Cape Cod to analyze values, beliefs, and logic of supporters and opponents. For example, one value found to lead to opposition is that the ocean is a special place that should be kept natural and free of human intrusion. One line of argument found to lead to support is: The war in Iraq is problematic, this war is “really” over petroleum, Cape Cod generates electricity from oil, therefore, the wind project would improve U.S. security. Based on analysis of the values and reasoning behind our interview data, we identify four issues that are relevant but not currently part of the debate.  相似文献

The Tubbataha Reefs Natural Marine Park, a UNESCO World Heritage Site in the Sulu Sea, Philippines, is an offshore marine protected area well known throughout the scuba diving community for its coral reefs and marine diversity. To address the perennial problem of park financing, the Tubbataha Management Board developed a fee collection and permit system in cooperation with the diving community. A willingness-to-pay survey conducted among divers in 1999 showed that the average diver was willing to pay U.S.$41 per visit. Using these results, a two-tiered pricing scheme was developed for foreign and local divers. After two years of fee collection, the total fee collected amounted to U.S.$65,000, which covered 28% of the annual recurring costs and nearly 41% of the core costs to protect Tubbataha. The experience shows the contribution of willingness-to-pay surveys in instituting user fees for long-term sustainable financing.  相似文献

Abstract

The passage of the Marine Plastics Pollution Research and Control Act of 1987 (MPPRCA), which codified Annex V of the International Convention for the Prevention of Pollution from Ships (MARPOL), has encompassed every commercial and recreational shipping and boating facility in the United States. As a group, these ports, harbors, and marinas form a significant, although proportionately small, portion of the coastline of the country. More important, the economic benefits derived from the complex shoreside infrastructures required for international ocean trade, commercial and recreational fishing, and pleasure boating indicate just how critical it is for these facilities to be in conformance with effective and prudent coastal zone and environmental management practices.  相似文献
