Mind the gap: Addressing the shortcomings of marine protected areas through large scale marine spatial planning 总被引:1,自引:0,他引:1
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

While the global network of marine protected areas (MPAs) has recently been evaluated in the light of bio-geographic targets, there has been no attempt to evaluate the relative conservation efforts made by the different nations with regards to their level of socio-economic development. Using information mostly gathered from the world database on protected areas (WDPA), this paper gives a comparative assessment of MPA progress in countries from different economic categories, ranging from advanced economies to least developed countries (LDCs). Potentially explanatory socio-economic and environmental factors, such as fishing activity and existence of vulnerable marine ecosystems, for variability between nations in the level of MPA implementation are also explored. Existing MPA databases demonstrate a clear gap between developed and developing nations in MPA establishment, with advanced economies accounting for two thirds of the global MPA network. Patterns of MPA use, however, remain extremely heterogeneous between countries within each development group. International agreements on marine conservation, above and beyond the influence of country socio-economic and environmental profiles, are identified as a stimulating factor to MPA implementation. The level dependence on marine resource extraction appears to impede MPA implementation, though the relationship is not statistically significant due to large heterogeneity among countries. Leading developed nations increasingly use MPAs to designate integrated and adaptive management areas, and implementation of large “no-take” reserves in relatively-pristine overseas areas continues to accelerate. These analyses highlight certain limitations regarding our ability to assess the true conservation effectiveness of the existing global MPA network and the need for improved indicators of MPA restrictions and management efforts. 相似文献

The establishment of marine protected areas (MPA) has been a common government response to increasing fishing, tourism and other human activities that lead to decline in coral and marine resources. MPAs often suffer inadequacy of funds and simply become “paper parks”. This study makes a case for the feasibility of a self-financing mechanism for MPAs by estimating potential surplus benefit that recreational users may gain from MPAs in Jamaica. These same recreational users in turn, might be willing to pay a small portion of that gain toward the management costs. With the help of a travel cost model and the visitors’ willingness to pay (WTP) estimates, we show that the management costs of the park amount to a negligible amount; less than 0.1% of the annual total WTP. Furthermore, using these WTP estimates and the findings from other stakeholders’ surveys (hotels, tour operators, etc.), the paper provides insights on user-supported funding policies, such as taxes and fees, which might sustain the operations of MPAs in Jamaica and the broader Caribbean region. 相似文献

Plans by government to accelerate the establishment of a national representative system of marine protected areas (NRSMPAs) in Australia have caused increasing disquiet within the fishing industry. Rock lobster fishers have raised concerns regarding plans to establish large “multiple‐use” MPAs that may or may not contain a substantial no‐take component in the continental shelf waters adjacent to the coast. Key industry concerns including the potential impacts on present and future harvest rates are examined. The industry response to government MPA policy in each of the major jurisdictions is outlined. An industry position developed at the National Rock Lobster Congress in Perth, Western Australia (September 2003) is put forward. The position advocates the need for an adjustment scheme to account for displaced effort, the need for government commitment to the development of management plans that include the long‐term monitoring of all MPAs, and the need for a thorough risk assessment process to be conducted before the establishment of an MPA. The issues raised in this paper should be relevant to the establishment of MPAs in an international context. 相似文献

Addressing social and economic considerations is crucial to the success of Marine Protected Area (MPA) planning and management. Ineffective social assessment can alienate local communities and undermine the success of existing and future MPAs. It is rare to critique the success of methods used currently to incorporate social and economic considerations into MPA planning. Three Australian MPA planning processes covering three states and incorporating federal and state jurisdictions are reviewed in order to determine how potential social impacts were assessed and considered. These case studies indicate that Social Impact Assessment (SIA) is under-developed in Australian MPA planning. Assessments rely heavily on public participation and economic modelling as surrogates for dedicated SIA and are followed commonly by attitudinal surveys to gauge public opinion on the MPA after its establishment. The emergence of issues around public perception of the value of MPAs indicates the failure of some of these proposals to adequately consider social factors in planning and management. This perception may have potential implications for the long term success of individual MPAs. It may also compromise Australia's ability to meet international commitments for MPA targets to gazette at least 10% of all its marine habitats as MPAs. Indeed, this is demonstrated in two of the three case studies where social and economic arguments against MPAs have been used to delay or block the future expansion of the MPA network. 相似文献

The relative paucity and heterogeneous distribution of marine protected areas (MPAs) indicates the need for better understanding of factors that foster MPA establishment at local, sub-national, and national levels. The relationship between national-level MPA establishment and geographic, ecological, social, and political factors that may drive patterns and trends in MPA establishment were assessed. A country's coastline length is the strongest predictor of both the number and spatial extent of MPAs. Controlling for coastline, the Human Development Index (HDI) and spatial overlap with designated conservation priority areas are positively correlated with MPA establishment. Surprisingly, some factors influencing MPA establishment in case studies, such as percentage of fishers within a population, were not correlated with MPA establishment on a national scale. These national dynamics explain a relatively small proportion of variation, however, indicating that other biological or social factors, as well as sub-national processes, also influence MPA establishment. Positive and negative outliers illuminate the importance of policy engagement at both national and local levels. Ensuring a supportive enabling environment at the national or even multi-national level can enhance success at the local level. 相似文献

Marine protected areas (MPAs) are increasingly being established to protect and rebuild coastal and marine ecosystems. However, while the high seas are increasingly subject to exploitation, globally few MPAs exist in areas beyond national jurisdiction. In 2010 a substantial step forward was made in the protection of high seas ecosystems with 286,200 km2 of the North-East Atlantic established as six MPAs. Here a summary is presented of how the world's first network of high seas marine protected areas was created under the OSPAR Convention, the main challenges and a series of key lessons learned, aiming to highlight approaches that also may be effective for similar efforts in the future. It is concluded that the designation of these six MPAs is just the start of the process and to achieve ecological coherence and representativity in the North-East Atlantic, the network will have to be complemented over time by additional MPA sites. 相似文献

Selected and managed effectively, regional networks of marine protected areas (MPAs) have the potential to be important strategies for conserving representative samples of global biodiversity and migratory species, and for the development of trans-national experience in resource management and conservation. This paper reviews current and proposed regional networks of MPAs, and describes the process of establishing an MPA network in the Red Sea and Gulf of Aden Region as a case study. Critical to the success of this network will be the implementation of a common, regionally agreed management framework, and the development of the necessary technical capacity and expertise in the planning and management of MPAs (currently lacking in several countries represented in the Network). This case study addresses the regional management framework, the mechanisms proposed to coordinate management of the participating MPAs, the mechanisms for strengthening regional capacity, and the potential constraints to achieving the objectives and goals of the network. 相似文献

California recently established a state-wide MPA network that extends over 1900 km of coastline and includes 124 MPAs totaling nearly 2200 km². Designing and implementing such an MPA network in a populous democratic state with a large number of ocean users required a balance of top-down and bottom-up governance strategies. A legal mandate for MPAs identified the goals for the network and stipulated that scientific knowledge should form the basis of MPA design, while political necessity led to a participatory stakeholder-driven MPA design process. At the time of publication, the oldest region of the network was just five years old, so it remains to be seen how the governance strategies employed in MPA planning will evolve to meet the challenges of long-term MPA management. 相似文献

The 1992 Convention on Biological Diversity has set ambitious targets for the establishment and management of protected areas. For the oceans, the overall aim is to establish, by 2012, an effectively managed, representative, global system of marine protected areas (MPAs) covering 10% of all marine ecological regions, comprising both multiple use areas and strictly protected areas. An analysis of data for three countries in Eastern Africa, where considerable efforts to promote MPAs by many agencies have been made over the past decade, shows that rapid progress has been made towards achieving this target. Since the first MPAs were established in the 1960s and 1970s, 8.7% of the continental shelf in Kenya, 8.1% in Tanzania and 4.0% in Mozambique has been designated, with the size of recently protected sites markedly larger than earlier sites. Commitments to expand the MPA networks in these countries would, if implemented, largely achieve the 10% coverage target. The location of existing marine protected areas shows good correlation with known sites of high species diversity; and coral reefs and Important Bird Areas are well represented. Management effectiveness of MPAs is also improving. However, there are major constraints to meeting the MPA target in these countries. Many habitats and species are not yet fully represented, the area closed to fishing is less than the recommended 20–30%, and capacity building is needed to improve many aspects of management. Furthermore, despite considerable investment in monitoring of coral reefs and other coastal habitats, the data available do not show clearly whether biodiversity and socio-economic objectives are being met. Although East African countries need to be congratulated for their vision, the results thus far indicate the urgency of both improving monitoring systems for measuring progress towards the targets, and also taking further steps to expand and improve management of existing MPAs. 相似文献

Can management effort be predicted for marine protected areas? New considerations for network design
《Marine Policy》2014
This study examined the level of management complexity (simultaneously occurring licensed human activities) within the currently designated Marine Protected Areas (MPAs) in Scottish waters and through modelling and statistical analysis determined which variables play an important role in defining the level of management effort required for each MPA. This study utilised surveyed distribution data for Priority Marine Features and modelled distribution data showing potential “Most Suitable” Priority Marine Feature habitat through the species distribution model, Maxent. Prediction indicators were developed through Spearman׳s Rank coefficients and a linear regression model. Results showed that, (1) there was a significant negative correlation between the management complexity score within 5 km of a MPA and the number of casework events (defined as any work or statutory consultation associated with an MPA, such as planning applications, discharges or new fisheries); and (2) a significant positive correlation between the number of casework events and location, number of features, and the type of features and most suitable scores. Calculations showed that Lochs Duich, Long and Alsh, Loch Sunart, Loch Sween and Loch Creran may potentially require most effort to manage once they are designated as MPAs. This study showed that it is possible to evaluate options within an MPA network to achieve cost effective options for the biodiversity and socio-economic objectives of MPA networks and that some MPAs are likely to be more efficient than others in terms of management time. 相似文献

The stalemate since 2012 over the establishment of marine protected areas (MPAs) in the Southern Ocean has been a source of debate within and outside the Commission for Conservation of Antarctic Marine Living Resources (CCAMLR). In 2015, China's support for the proposal for the establishment of a Ross Sea MPA was commended as a major step forward. As the newest Member of the CCAMLR, China refrained itself from commenting specifically on the issue of MPAs in the previous years, and had not articulated clearly its basic position until 2014. In light of its basic position and practices, China may become more active, maintain its basic position and take a case-by-case approach in relation to other MPA proposals. Moreover, bilateral interaction is helpful in finding practical solutions. 相似文献

Marine Protected Areas (MPAs) are a cost-efficient and management-effective tool. Fishery Resource Conservation Zones (FRCZs) are one type of MPA in Taiwan, and they were designated to ensure the sustainability of fishery resources since 1976; however, government appropriations are the only financing source for FRCZs, leading to manpower and equipment shortages for FRCZ management. This study selected the Touching and Suao FRCZs in Yilan County of Taiwan as cases studies. To assess the feasibility of establishing a sustainable financing mechanism for MPAs, the Contingent Valuation Method (CVM) was applied to examine respondents׳ willingness to pay (WTP) to setup a fund for FRCZ management. The empirical results indicated that approximately 90% of respondents would be willing to donate funding for MPAs, and the WTP per respondent is NT$586.51 (US$19.6). Thus, establishing an MPA fund is a feasible way to operate Taiwanese MPAs through a co-management framework involving the central government, local government, local communities and stakeholders. However, based on our empirical results, a co-management financing mechanism for MPAs should be established to ensure stable and diverse financing sources. 相似文献

According to the United Nations (UN) Millennium Ecosystem Assessment, there has been a dramatic decline in global biodiversity. The UN has made a global appeal for all countries to mitigate their impact on the environment. Marine environmental protection is one of the most critical and urgent issues in the world and many countries have commenced establishing marine protected areas (MPAs) by implementing ecosystem-based management (EBM) concepts. MPA planning has been considered one of the simplest and most effective methods to protect marine environments. Taiwan has recently developed policies that have focused on its marine environment, and there are plans to increase the size of Taiwan׳s MPAs to 20% of its total ocean territory by 2020, thereby achieving a sustainable ocean. To achieve this goal, the government must address specific difficulties associated with the location of MPAs and relevant zoning strategies. This study establishes MPA protection principles and a zoning framework for MPAs in Taiwan by using Gueishan Island in Yilan County as a case study site to examine specific zoning strategies. The protection of 3 objectives (hydrothermal vents, cetacean, and fisheries resources) is discussed in this paper. Multi-criteria spatial analysis and a geographic information system are applied to identify the most crucial area to protect. To understand the stakeholders׳ opinions and concerns regarding the proposed zoning framework, this research conducted in-depth interviews with experts and stakeholders. MPAs zoning strategies are formulated at the conclusion of this study that could assist in protecting critical marine resources and avoiding conflicts among various usages of the marine area. 相似文献

A marine protected area (MPA) potentially generates a wide range of consumptive use, non-consumptive use and non-use values that include: critical habitat protection, conservation of marine biodiversity, recovery of threatened and endangered marine species, increased recreational benefits and increased biomass of harvested marine species. To help assess whether such values exceed the potential costs of MPAs, this paper provides a policy-enabling framework that reviews the existing theoretical and practical instruments and approaches that can be used in the ex-ante evaluation of MPAs. This framework is in three parts. First, a range of alternative monetary and non-monetary techniques to estimate three key economic benefits of MPAs: consumptive, non-consumptive use and non-use values are presented. Second, three decision protocols that can be applied to determine the desirability of establishing MPAs are described. Third, caveats of these approaches and the necessity to accommodate social needs of the communities are provided. The framework shows that biological and ecological considerations together with economic viability and socio-economic factors can and should be taken into account when deciding about when and where to establish MPAs and of what size. 相似文献

This paper examines the establishment of marine protected areas (MPAs) in remote small island settings with specific reference to the Portuguese island of Corvo in the Azores. This case study represents different approaches to marine conservation, ranging from an informal community-based no-take MPA to a government-driven multi-purpose natural park, involving diverse local and external actors interacting over an extended period of time. In-depth interviews were used to explore the perceptions of local and expert stakeholders about positive and negative aspects of MPA establishment. This demonstrated how differing approaches have led to varying degrees of MPA effectiveness. From the community-based MPA, several key ingredients for effective MPA establishment were identified, including engaging and empowering local communities, clear definition of goals, visible MPA outputs and community enforcement based on high levels of support and peer group pressure. However, in a context of complex marine resource use, the limitations of community-based initiatives prevent them from achieving broad ecosystem conservation goals. These might be better achieved through government-driven MPAs, provided that they are integrated in a wider regional marine strategy and that there is political will to effectively implement conservation measures and to allocate resources for management, enforcement and monitoring. 相似文献

Against a background of international commitments to establish ecologically coherent and representative MPA networks, and the UK Marine Bill which aims to implement these commitments, the larval dispersal potential of 31 rare/scare benthic invertebrates is investigated and it is found that over half have a low dispersal potential (<1 km). On the basis of this, interviews with experts and an analysis of relevant literatures, it is argued that the establishment of representative MPA networks may be a reachable objective, as it is scientifically more realistic and thereby more defensible, whilst the aim of establishing ecologically coherent MPA networks may be a bridge too far. 相似文献

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
