In the North-east Atlantic Ocean there are 550 inshore and offshore MPAs established to accomplish a high diversity of objectives, which can be classified into 24 different types of MPA designations. Only 153 of these MPAs have a management plan (MgP) --the basic tool required for an effective management. Amongst these, only 66 are actually managed, i.e. they have the staff and resources required to operate the plan. A common characteristic of these MPAs is the lack of standardized indicators of their performance. In order to address this issue, an alternative approach was developed based on the assessment of management performance using the expert knowledge and perceptions of managers operating MPAs, a universal source of information that could allow overcoming the usual gaps due to the restrictions in coverage of scientific monitoring and assessments. MgPs showed differences among countries but were homogeneous within each country, reflecting the usual top-down approach in the establishment of MPAs. Compliance with the qualitative objectives present in MgPs was higher than compliance with quantitative ones (87% versus 50%), and the MPAs that most successfully achieved their objectives were those with regular monitoring. This analysis also shows that beyond these objectives, the establishment of an MPA and the activities developed as a consequence of its creation have a positive socio-economic impact on the local human community.  相似文献

The state of Rhode Island's Ocean Special Area Management Plan (Ocean SAMP) is the first marine spatial plan in the United States to be formally approved by the federal government as an element of a state's Coastal Management Program. The 3800 km2 Ocean SAMP region includes waters under both state and federal jurisdiction. The Ocean SAMP applies the inclusive, ecosystem-based approach to marine spatial planning recommended by the National Ocean Commission in 2004 that is a feature of the National Ocean Policy promulgated in 2010. It places within a larger spatial planning context the impact assessment process that is the basis for the issuance of leases and permits requested by a developer for a specified activity at a defined marine site. The Ocean SAMP was prepared over a two and a half year period of information generation, analysis, consultation, planning and policy making prompted by the need to identify potentially suitable sites for anticipated offshore wind farms. Its highly consultative approach builds upon the 30 years of experience of the Rhode Island Coastal Program in developing and implementing special area management plans (SAMPs) for coastal and marine areas where conflicts over needs for both development and conservation demand special attention and negotiation among stakeholders with different interests. The phases in the development and approval of the Ocean SAMP, and the prospects for successful implementation are examined through frameworks suggested for the preparation of a governance baseline put forward by the international Land Ocean Interactions in the Coastal Zone (LOICZ) program.  相似文献

This paper presents the results of a survey of public awareness of marine environmental issues within the context of the UK's National Maritime Museum. It was found that public interest in marine environmental issues is significant, but that gaps exist in terms of issue-specific awareness and that the availability of independent information on marine issues is limited. It is concluded that there are significant opportunities to develop the Museum's role in raising public awareness of marine environmental issues that build on its current activities and that of the Museum's partners.  相似文献

The global community's ability to assess the environmental effects of marine scientific research (MSR) as required by the 1982 United Nations Convention on the Law of the Sea's (UNCLOS) marine environment provisions (MEP) is limited, as shown by experimental activities that intentionally manipulate the marine environment. Such work enhances knowledge of the ocean, but it may also have significant environmental effects. This growing use of the ocean as a laboratory has global scientific, environmental, legal and policy implications. Examined here is the relationship between the MSR and the MEP provisions of UNCLOS. International, science-driven guidelines are proposed.  相似文献

This paper provides an opportunity to examine the involvement of English Heritage in the development of policy and practice with particular regard to how archaeology and features of historic interest are addressed under national legislation, international conventions and EU law. In this paper we provide an explanation of action taken to support conservation, understanding and enjoyment of the historic environment, such as those sites that are legally protected as historic shipwreck sites, and other features that comprise the historic environment, but which are recognised and protected through other legal mechanisms e.g., military vessels and aeroplanes. It is apparent to us that when considering the management agenda for the marine environment attention is also given to archaeological material that predates tidal inundation, as well as the subsequent legacy of maritime activities. To support this approach we examine how the historic environment is defined and included in objectives, policy and law, such as the Marine and Coastal Access Act 2009, as well as other European or international programmes to promote marine policy and spatial planning. In the years since the National Heritage Act 2002, and the empowerment of English Heritage to support marine projects, we assess the production of explanatory statements and guidance to inform protection in recognition of how change may affect historic environment features. In addition, it is apparent that extensive development is now taking place further offshore (e.g., renewable power projects) and we direct attention at how English Heritage's role is affected by legally defined maritime territorial limits that dictate interpretation of what the marine environment comprises and how such limits influence regulatory controls placed on the management of cultural heritage.  相似文献

This article sets out to explore the extent to which the maritime policies that have been formulated in recent years are public policies on a par with other State-level policies, or whether the geographical domain where they are applied makes them exceptional. Maritime policy and territorial structure are very closely related, and it can be seen that maritime policies are beginning to shift towards the domain of State internal affairs, necessitating the rethinking of the way powers are distributed between territorial bodies that have the legal power to be involved in the formulation of these policies and some instruments, such as marine spatial planning.  相似文献

A blind faith in the ability of MPAs to counteract loss of biodiversity is fraught with risk, especially when MPAs are poorly planned and when the consequences of establishing MPAs are not adequately thought out. MPA shortcomings are categorized as one of five main types: (1) MPAs that by virtue of their small size or poor design are ecologically insufficient; (2) inappropriately planned or managed MPAs; (3) MPAs that fail due to the degradation of the unprotected surrounding ecosystems; (4) MPAs that do more harm than good due to displacement and unintended consequences of management; and (5) MPAs that create a dangerous illusion of protection when in fact no protection is occurring. A strategic alternative, which fully utilizes the strengths of the MPA tool while avoiding the pitfalls, can overcome these shortcomings: integrating marine protected area planning in broader marine spatial planning and ocean zoning efforts.  相似文献

Preparedness to adapt to the impacts of climate change was assessed for three important sectors of activity within the Irish coastal and marine environment, namely tourism, fisheries, and conservation of biodiversity. Information on the current status of each sector is a valuable point of reference in terms of accessing contribution to the implementation of future national adaptation efforts. A modified version of the National Adaptive Capacity (NAC) framework developed by the World Resources Institute was used to assess the three sectors of activity. This framework is structured around five functions: assessment, prioritisation, coordination, information management, and climate risk reduction; results of the assessment suggest that all three sectors are at the nascent stages of the climate change adaptation process. Currently there is no dedicated national policy guidance or legal support mechanism on adaptation in Ireland; hence there is no national financial commitment to support implementation of adaptation actions for any of the sectors assessed. Subjecting these three selected sectors of activity to such an assessment enables identification of existing actions that can potentially support current adaptation, as well as where issues such as knowledge gaps and lack of policy support hinder progress.  相似文献

The realisation that the world’s oceans play an important role in climate regulation and many territory activities, notably food production, coupled with economic changes and the rapid advancement in ocean technology have seen a shift in the perception of the importance of marine resources. This increased focus on marine resources means that governments and policy-makers require accessible and reliable information regarding the role of the marine sector. This information may then be used to formulate new environmental and economic policy measures. The aim of this paper is to define, describe and quantify the value of the marine sector in Ireland. This paper outlines a methodology that provides a robust analysis of the Irish marine sector for 2007. It was found that in 2007 the Irish marine sector contributed €1.44 billion in GVA to the wider Irish economy and employed over 17,000 individuals in full time equivalents.  相似文献

This article examines coastal residents' awareness and knowledge about impacts of seawater desalination on marine ecosystems Carlsbad, California. The paper explores to what extent sociodemographics, motivational factors, and information use shape public awareness and self-assessed and factual knowledge. Data was collected using a mail survey (n=330) from a random sample of residents in Carlsbad. Both self-assessed and factual knowledge about the desalination plant and its impacts on marine ecosystem were low, with only two of 11 factual questions answered correctly by more than 50% of respondents. Gender, frequency of ocean use, and use of distinct information sources correlated positively with greater factual knowledge. Education, age, time of residency in local community, membership in an NGO, and place attachment to marine areas did not increase factual knowledge. Findings also demonstrate that knowledge shaped attitudes towards the seawater desalination plant as greater knowledge about marine impacts reduced support.  相似文献

Marine Recreational Fishing (MRF) is an important activity in Europe, with 9 million fishers and generating annually € 6 billion in direct expenditures. However, there is a lack of data and understanding of MRF in Europe, particularly in Southern countries, which prevents a number of fish stocks from being effectively assessed and managed. In November 2016, a participatory workshop on MRF was held in Vigo (Spain) to identify challenges and opportunities for data collection, and to diagnose key research gaps and management issues for MRF in the Southern European Atlantic. Experts from a wide range of disciplines (researchers, policy makers, fisheries managers and commercial and recreational fishers) highlighted that the management of MRF is a challenge due to complex and dispersed legal frameworks, with multiple administrations involved, and overlapping uses of space with commercial fishing, aquaculture, navigation and tourism, among others. The lack of strong and representative fishing associations hampers research and management initiatives. Effective communication between recreational fishers, researchers and fisheries managers is also lacking. Despite the ecological, social and economic relevance of MRF, there is no systematic and comprehensive collection of information on fishing effort, recreational catches, expenses, social profile and access conditions of European recreational fishers. These data would be useful to avoid biases in the assessment of recreational fisheries due to the great diversity of ecosystems, species and typologies of users. Strategic recommendations and research priorities were also identified to address knowledge gaps and are discussed in the context of the management of MRF across Europe.  相似文献

From 2009 to 2011, marine spatial planning (MSP) rapidly gained visibility in the United States as a promising ocean management tool. A few small-scale planning efforts were completed in state waters, and the Obama Administration proposed a framework for large-scale regional MSP throughout the U.S. Exclusive Economic Zone. During that same time period, the authors engaged a variety of U.S ocean stakeholders in a series of dialogs with several goals: to share information about what MSP is or could be, to hear stakeholder views and concerns about MSP, and to foster better understanding between those who depend on ocean resources for their livelihood and ocean conservation advocates. The stakeholder meetings were supplemented with several rounds of in-depth interviews and a survey. Despite some predictable areas of conflict, project participants agreed on a number of issues related to stakeholder engagement in MSP: all felt strongly that government planners need to engage outsiders earlier, more often, more meaningfully, and through an open and transparent process. Equally important, the project affirmed the value of bringing unlike parties together at the earliest opportunity to learn, talk, and listen to others with whom they rarely engage.  相似文献

Our global oceans are threatened by climate change, overfishing, pollution and a growing list of other impacts that demonstrate an urgent global need for sustainable ocean management. Whilst marine conservation initiatives and protected ocean spaces have increased over recent years, ocean management still lags behind the terrestrial sectors in incorporating and involving communities in its development. ‘Social licence to operate’ is used broadly across the terrestrial literature, but its understanding and application within the marine has been limited to date. This review sought to collate and synthesise instances of social licence in the marine realm as documented in the literature, aiming to create an understanding that may inform future research and development of social licence. Its results determine that social licence is yet an emergent concept in the marine sector but there may be great potential for its application in the marine context. Social licence has become an important theme for development in marine industry and resource use, particularly towards exploring communication and stakeholder engagement. This paper identifies future themes and areas requiring investigation and application in this domain.  相似文献

The emerging ocean energy industry, which seeks to utilise waves and tides to generate electricity, is developing in many jurisdictions. The UK, and Scotland in particular, is strongly interested in these technologies, and has made considerable efforts to reform its marine governance processes to better meet the needs of innovative new marine industries. This paper provides an industry perspective on this regulatory framework, reporting on the experiences of ocean energy project and technology developers. Semi-structured interviews with companies with practical experience with Scotland's regulatory framework provide evidence of a number of legal and regulatory challenges, as well as interesting insights into how developers are interacting with new marine governance systems. The paper details the findings of these interviews and offers some suggested directions for future research.  相似文献

Given competing objectives vying for space in the marine environment, the island of Bermuda may be an ideal candidate for comprehensive marine spatial planning (MSP). However, faced with other pressing issues, ocean management reform has not yet received significant traction from the government, a pattern seen in many locations. Spatial planning processes often struggle during the proposal, planning, or implementation phases due to stakeholder opposition and/or government wariness to change. Conflict among stakeholders about management reform has also proven to be a deterrent to MSP application in many locations. With these obstacles in mind, a detailed stakeholder survey was conducted in Bermuda to determine awareness, attitudes and perceptions regarding ocean health, threats to ocean environments, the effectiveness of current ocean management, and possible future changes to management. How perceptions vary for different types of stakeholders and how attitudes about specific concerns relate to attitudes about management changes were examined. Overall, the results indicate a high degree of support for spatial planning and ocean zoning and a high level of concordance even among stakeholder groups that are typically assumed to have conflicting agendas. However, attitudes were not entirely homogeneous, particularly when delving into details about specific management changes. For example, commercial fishers were generally less in favor, relative to other stakeholder groups, of increasing regulations on ocean uses with the notable exception of regulations for recreational fishing. Given the results of this survey, public support is likely to be high for government action focused on ocean management reform in Bermuda.  相似文献

Ecosystem-Based Management (EBM) has gained international popularity in recent years, but the lack of consensus on its definition has precluded the use of a universal implementation framework. The large number and variety of principles that make up EBM, and the diversity in perspectives among key management players, has impeded the practical application of EBM. Agreement on a list of the essential ingredients of EBM is vital to successful application. A frequency analysis of EBM principles was conducted to identify the Key Principles that currently define EBM, from a list of twenty-six principles extracted from a subset of the EBM theoretical/conceptual literature (covering a range of published sources across disciplines and application types). Fifteen Key Principles were identified (in descending frequency of appearance in the literature): Consider Ecosystem Connections, Appropriate Spatial & Temporal Scales, Adaptive Management, Use of Scientific Knowledge, Integrated Management, Stakeholder Involvement, Account for Dynamic Nature of Ecosystems, Ecological Integrity & Biodiversity, Sustainability, Recognise Coupled Social-Ecological Systems, Decisions reflect Societal Choice, Distinct Boundaries, Interdisciplinarity, Appropriate Monitoring, and Acknowledge Uncertainty. This paper also examines the development of EBM principles over time, leading to predictions on the directions EBM will take in the future. The frequency analysis methodology used here can be replicated to update the Key Principles of EBM in the future. Indeed, further research on potential emerging Key Principles such as ‘Consider Cumulative Impacts’, ‘Apply the Precautionary Approach’ and ‘Explicitly Acknowledge Trade Offs’ will help shape EBM and its successful application in the management of marine activities.  相似文献

In 2001, the National Oceanic and Atmospheric Administration (NOAA) and the Ministry of Maritime Affairs and Fisheries Integrated Coastal and Ocean Resources Scientific and Technical Arrangement was signed to pursue scientific and technical cooperation in integrated coastal and ocean resources management in the mutual interest of the participants. Over the last 6 years, the cooperation has been very beneficial, particularly for advancing marine science and management programs in Korea, such as Deep Sea Aquaculture, Sea Grant College Program, Marine Protected Areas, and Ocean Observations. The benefits to NOAA from the cooperation include Deep-ocean Assessment and Reporting of Tsunamis (DART) buoys, ocean and coastal observations, GEOSS program, and Global Program of Action. Also the cooperation has spillover effects on other ocean science and technological arrangement between US and Korea. This article reviews purpose, obstacles, and achievement of the cooperation and suggests recommendations for the future steps.  相似文献
