近岸海域的生态系统管理,要求对海洋健康进行综合的评估以及对人工调控进行科学的指导,进而促进可持续发展。本文构建了定量化方法,用于评估当前的和近期的基于生态系统服务的海洋健康。以莱州湾为例的研究结果表明,当前的海洋健康指数分值为0.7856(总分为1.0);通过对负面压力进行不同强度的人工调控,得到近期海洋健康预计的变化范围为0.5551到0.8041。具体地说,本文评估得到当前的海洋健康主要表现为文化服务和供给服务基本优秀,而支持服务和调节服务不够良好。若不对持续增长的压力采取有效的调控措施,该近岸海域生态系统会在近期丧失部分支持服务和调节服务;若负面压力被完全控制,该近岸海域生态系统服务的分类等级会得到小幅提升。另外,应进一步加强对生态系统服务尤其是文化服务和调节服务的宣传教育。本文的分析过程和量化结果,为进一步指导人工调控提供了灵活的工具,有助于海岸带区域的生态系统管理。 相似文献

How can uncertain fisheries science be linked with good governance processes, thereby increasing fisheries management legitimacy and effectiveness? Reducing the uncertainties around scientific models has long been perceived as the cure of the fisheries management problem. There is however increasing recognition that uncertainty in the numbers will remain. A lack of transparency with respect to these uncertainties can damage the credibility of science. The EU Commission's proposal for a reformed Common Fisheries Policy calls for more self-management for the fishing industry by increasing fishers' involvement in the planning and execution of policies and boosting the role of fishers' organisations. One way of higher transparency and improved participation is to include stakeholders in the modelling process itself. The JAKFISH project (Judgment And Knowledge in Fisheries Involving StakeHolders) invited fisheries stakeholders to participate in the process of framing the management problem, and to give input and evaluate the scientific models that are used to provide fisheries management advice. JAKFISH investigated various tools to assess and communicate uncertainty around fish stock assessments and fisheries management. Here, a synthesis is presented of the participatory work carried out in four European fishery case studies (Western Baltic herring, North Sea Nephrops, Central Baltic Herring and Mediterranean swordfish), focussing on the uncertainty tools used, the stakeholders' responses to these, and the lessons learnt. It is concluded that participatory modelling has the potential to facilitate and structure discussions between scientists and stakeholders about uncertainties and the quality of the knowledge base. It can also contribute to collective learning, increase legitimacy, and advance scientific understanding. However, when approaching real-life situations, modelling should not be seen as the priority objective. Rather, the crucial step in a science–stakeholder collaboration is the joint problem framing in an open, transparent way. 相似文献

The contradiction between the claim for integrated management of the coastal areas by the UN Conference on Environment and Development (UNCED, 1992), on the one hand, and the persistence of analytical epistemological approaches by the scientific community on the other, is discussed. In this context, it is emphasised how the modern approach led to the desegregation of the ocean into two realms, namely the coastal ocean subject to national jurisdiction, and the international ocean, making it difficult to design and operate integrated management. Moreover, the international ocean is vertically subdivided into two realms, namely the water column, having the status of res nullius, and the deep seabed, claimed as patrimony of mankind; hence the increasing difficulty in operating the protection of the ocean ecosystem and the efficient use of its resources while the human pressure on the ocean is growing without precedent. A positive feedback is needed between science and policy, the former being encouraged to overcome the analytical, modern approach; the latter being keen to consider the long term humankind-sensitive interest above the national interests. The role of geography in contributing to these prospects is discussed in the final part. 相似文献

Politics and independent scientific advice in RFMO processes: A case study of crossing boundaries 总被引：1，自引：0，他引：1
Tom Polacheck 《Marine Policy》2012,36(1):132-141
Provision of independent scientific advice is central to the operation of regional fisheries management organizations (RFMOs) even though RFMOs are largely policy (and political) instruments. Political pressures and intervention in science and crossing of the boundaries between scientific and political processes, however, appear to be relatively common. A case study is presented to illustrate some ways in which this occurs. It involves a paper that was withdrawn from scientific meetings of two RFMOs as a result of largely political (rather than scientific) concerns. The details involved in this incident are important for understanding the ways in which political intervention in independent scientific process can and does occur. Moreover, unless one is directly involved in actions of this kind, it is impossible from the reports of RFMOs' scientific bodies to assess whether, and the extent to which, there has been political intervention in the scientific process. It is argued that the nature of the working arrangements in these scientific committees can engender deliberate or inadvertent crossing of the boundaries between scientific independence and the political processes of RFMOs, both of which are important components of RFMO operation. Further, there is very little documentation or assessment of the generic extent of such problems. No simple solutions or reforms exist for isolating scientific advice from political agenda in the processes of RFMOs but it is suggested that increased discussion of the problem along with better understanding and clarity of the role of science in the management process may lead to improved recognition of the importance of independent scientific analyses and advice. 相似文献

The Pacific Island Regional Ocean Policy (PIROP), which was released in 2002, provided the framework for ocean governance in the Pacific region. Since then there have been a myriad of policy documents and institutional arrangements that have been developed to address ocean governance issues, however, little progress has occurred with regard to the actual implementation of PIROP. This paper examines the region's progress in establishing integrated oceans management, and how this fits with the use of marine spatial planning and area based management tools, such as marine protected areas. It argues that policy making in this region encounters the usual difficulties with integrated policy approaches experienced elsewhere but that these difficulties are further accentuated when applied to developing nations that are highly dependent on external support. It suggests a way forward for the future with development of action plans, implementation and the practical application of those plans including a regional contextualisation/analysis of progress against regional objectives. 相似文献

In the European Union, fisheries managers rely on the expertise of scientists to provide scientific advice for the fisheries management process. Yet the boundary between science and policy is not only imprecise, but one that is also socially constructed. Negotiations take place between two main groups, managers and scientists, surrounding the roles and expectations each has towards the other. Pressure is placed upon each group to conform to the role expectations of the other. Taking note of reform attempts of the European fisheries management system which are already under way, we suggest that reform must provide for effective two-way communication between scientists and managers, which recognises their different needs and role identities, and focuses on both areas of conflict and areas of common interest, in order that the system better meets the requirements of each party, ultimately aiding in the shared goal of the sustainable use of fisheries resources. 相似文献

Transitioning ocean governance into an ecosystem-based approach requires improved knowledge of ecosystems and existing management systems. While there has been increased effort to compile and synthesize ecological data, relatively little scholarship has been focused on improving and understanding ocean management systems. This paper presents a unique dataset that makes objective analyses of ocean management possible across multiple jurisdictions and sectors in the California Current. Following an explanation of the criteria used to compile relevant statutes and regulations, the paper suggests applications for the dataset including education and policy uses and ecosystem-based management tool development to identify and measure problems of fragmented management. 相似文献

It has been suggested that the fisheries management process with multiple, informed stakeholders and socio-economic, political, and scientific complexity can be considered a governance network. This exploratory study applied communication network analysis (CNA) measures and methods to assess two cases of US federal fishery management in the Northwest Atlantic—Atlantic herring and sea scallop. Through questionnaires and interviews, CNA maps were constructed and quantitative measures of network structure and function (density, weighted average path length) and centrality measures for individual network members (degree, betweenness) were derived using InFlow software. The results show that fishery governance networks are horizontally and vertically integrated across levels of government and public–private–nonprofit sectors. The findings validated existing understanding of fisheries management as a contested, competitive management context among stakeholders, and provided new insights about the effectiveness of information sharing across the network and the critical role of bridgers connecting disparate subgroups. Fisheries management can be conceptualized and analyzed as governance networks, and the paper discusses additional research questions, refinements needed for application of the research methods, and ramifications for managers (e.g., can resource managers manage networks). 相似文献

The range of the Cape fur seal Arctocephalus pusillus pusillus population largely coincides with the region of the cold, nutrient-rich Benguela Current Large Marine Ecosystem (BCLME) adjoining the west coast of South Africa, Namibia and Angola. Range-wide scientific monitoring of the seal population was initiated in the 1970s to inform on population management questions related to commercial seal harvesting and seal–fishery interactions. Since the 1970s, seal-related management goals have changed, especially in South Africa where seal harvesting ceased in 1990 and government has conformed to scientific advice against the culling of seals for the intended benefit of fisheries. However, renewed impetus has been provided to seal research and monitoring through the expansion of the ‘ecosystem-based management’ concept in the region, as well as improved international cooperation in the management of marine resources. Together with wide-scale ecosystem changes in the marine environment, and forecast effects of global climate changes, this has justified the continuation and improvement of range-wide scientific monitoring of Cape fur seals. We prioritised seal monitoring based on cost, effort, and relevance to monitoring objectives that have been identified for the region, with consideration given to the conservation status of top predators, interspecific and predator-fishery interactions and the potential use of Cape fur seals as indicators of ecosystem health. An integrated approach incorporating a suite of life-history attributes of seals is recommended, useful monitoring tools are discussed and the need for coordinated monitoring effort and standardisation of sampling techniques is emphasised. 相似文献

The eastern stock of Atlantic bluefin tuna (thunnus thynnus) was recently nominated for protection under the Convention on International Trade in Endangered Species of Flora and Fauna (CITES). That nomination failed, which leaves management of the heavily overfished stock in the hands of the International Commission for the Conservation of Atlantic Tunas (ICCAT). This paper reviews the history of ICCAT management of Atlantic bluefin tuna to show that (1) early elimination of competitive forces prevented agreement on management in keeping with scientific advice, resulting in the steep decline of the stock, (2) even just the threat of a CITES listing can provide temporary impetus for marked improvement in ICCAT management, and (3) long-term sustainable management by ICCAT will require continued economic and political pressure. 相似文献

The recent overexploitation of East Atlantic and Mediterranean bluefin tuna stock has been well documented in the media where it has become the archetype of overfishing and general mis-management. Beyond the public debate, the crisis also highlighted how the interactions between science and management can change through time according to the awareness of the public opinion. To reflect these issues, the history of Atlantic bluefin tuna overfishing is first described. Then, the major uncertainties that undermine the current scientific advice are summarized and the importance of reducing their impacts by improving knowledge and developing robust scientific framework is considered. The study also discusses how uncertainty was used by different lobbies to discredit science-based management. The recent improvement in bluefin tuna stock status following the implementation of the rebuilding plan shows that, despite uncertainty in the scientific advice, the management of a heavily exploited fish stock can be positive when there is a political will. However, optimizing long-term yields of modern fisheries implies good science. The study concludes by advocating for the implementation of a scientific quota that should be part of the management framework to support the scientific advice. 相似文献

The majority of fishery stocks in the world are data limited, which limits formal stock assessments. Identifying the impacts of input data on stock assessment is critical for improving stock assessment and developing precautionary management strategies. We compare catch advice obtained from applications of various datalimited methods(DLMs) with forecasted catch advice from existing data-rich stock assessment models for the Indian Ocean bigeye tuna(Thunnus obesus). Our goal was to evaluate the co... 相似文献
