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

Marine protected areas are promoted as a resource management tool for balancing ecological integrity with economic activity. However, MPAs frequently fail to achieve integrated, substantive outcomes. Participation failure is a common symptom of implementation failure. MPA experts often conclude that the remedy, in part, lies in better communication, with the implicit assumption that participation and communication are conjoined or synonymous. In this paper, the geography of communication in marine environments is analyzed as distinct from participation. It is argued that the logistical challenges of communicating in marine time and space must be taken into account beginning with the pre-implementation stage of an MPA; this requires recognition and analysis of the political nuances of whose space, whose time, and whose terms for communication. Research in Wakatobi National Park in Indonesia determined that marine managers and local communities have divergent experiences of participation, prompting three insights. First, the timing of public consultations must accommodate the variable rhythms of life in fishing communities in order to ensure broad representation. Second, co-presence in fishers’ space is critical for effective communication of marine knowledge and management strategies. Third, the deployment of ‘participation time’ by decision-makers communicates the value – or lack thereof – they place on fishing people and collaboration. The constructivist spatial analysis of communication presented here provides a model for MPA decision-makers and managers to identify, overcome and mobilize communication geographies that affect participation in sustainable development.  相似文献

The ecologically and socio-economically important marine ecosystems of Europe are facing severe threats from a variety of human impacts. To mitigate and potentially reverse some of these impacts, the European Union (EU) has mandated the implementation of the Marine Strategy Framework Directive (MSFD) in order to achieve Good Environmental Status (GES) in EU waters by 2020. The primary initiative for achieving GES is the implementation of coherent networks of marine protected areas (MPAs). Marine reserves are an important type of MPA in which no extraction is allowed, but their usefulness depends upon a number of ecological, management, and political factors. This paper provides a synthesis of the ecological effects of existing European marine reserves and the factors (social and ecological) underlying their effectiveness. Results show that existing European marine reserves foster significant positive increases in key biological variables (density, biomass, body size, and species richness) compared with areas receiving less protection, a pattern mirrored by marine reserves around the globe. For marine reserves to achieve their ecological and social goals, however, they must be designed, managed, and enforced properly. In addition, identifying whether protected areas are ecologically connected as a network, as well as where new MPAs should be established according to the MSFD, requires information on the connectivity of populations across large areas. The adoption of the MSFD demonstrates willingness to achieve the long-term protection of Europe's marine ecosystems, but whether the political will (local, regional, and continent wide) is strong enough to see its mandates through remains to be seen. Although the MSFD does not explicitly require marine reserves, an important step towards the protection of Europe's marine ecosystems is the establishment of marine reserves within wider-use MPAs as connected networks across large spatial scales.  相似文献

Measuring the ‘level of compliance’ has emerged as a key performance indicator for MPA success internationally. Accurate interpretation of quantitative and qualitative compliance data is critical for determining which compliance activities contribute to specific management outcomes. To demonstrate the value of enforcement data in effective MPA management, more than 5000 enforcement actions from 2007 to 2013 from five New South Wales (NSW) Marine Parks were analysed. Specifically, it was tested whether through time: (i) the number of enforcement actions standardised by surveillance effort declined-indicating that ‘general deterrence’ was being achieved; (ii) the number of repeat offenders decreased-indicating that ‘specific deterrence’ was being achieved; (iii) the number of ‘local community’ enforcement actions standardised by surveillance effort declined-indicating growing support for marine parks was being achieved at the community level; and (iv) the percentage of young offenders (<25 yr) had declined-indicating that education programs targeting young adults were successful. Results indicated that general deterrence was not being achieved, with offence rates being relatively stable between years. In contrast, compliance measures were achieving individual deterrence, with the percentage of repeat offenders being very low (0.13–0.83%). Although compliance strategies may be making some progress in improving local compliance in some marine parks, the overall offence rate of local communities was concerning. The data suggested that there were major differences in compliance rates among age groups of offenders over time, although the percentage of young offenders declined over time in three marine parks. Over the six-year data collection period, there was no discernable improvement in compliance rates in most NSW Marine Parks. Overall, the significant value of collecting and analysing information on enforcement activities for MPAs was demonstrated, an often neglected aspect of their management world-wide.  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

Conservation success is often predicated on local support for conservation which is strongly influenced by perceptions of the impacts that are experienced by local communities and opinions of management and governance. Marine protected areas (MPAs) are effective conservation and fisheries management tools that can also have a broad array of positive and negative social, economic, cultural, and political impacts on local communities. Drawing on results from a mixed-methods study of communities on the Andaman Coast of Thailand, this paper explores perceptions of MPA impacts on community livelihood resources (assets) and outcomes as well as MPA governance and management. The area includes 17 National Marine Parks (NMPs) that are situated near rural communities that are highly dependent on coastal resources. Interview participants perceived NMPs to have limited to negative impacts on fisheries and agricultural livelihoods and negligible benefits for tourism livelihoods. Perceived impacts on livelihoods were felt to result from NMPs undermining access to or lacking support for development of cultural, social, political, financial, natural, human, physical, and political capital assets. Conflicting views emerged on whether NMPs resulted in negative or positive marine or terrestrial conservation outcomes. Perceptions of NMP governance and management processes were generally negative. These results point to some necessary policy improvements and actions to ameliorate: the relationship between the NMP and communities, NMP management and governance processes, and socio-economic and conservation outcomes.  相似文献

Global decline of marine resources has triggered a worldwide demand for changing the way ocean resources are managed. Ecosystem-based management approaches have emerged using marine protected areas (MPA) as the main tool. Several classifications of marine protected areas benefits have been made, but all have focused only on the benefits to humans, neglecting many important benefits accrued to nature. This paper presents a new comprehensive classification of MPA benefits that will provide scientists and managers with an inclusive framework to accurately identify and account for all possible benefits derived from MPAs. The paper also analyses the methods available for valuing these benefits. A total of 99 benefits were identified within nine main categories: fishery, non-fishery, management, education/research, cultural, process, ecosystem, population and species benefits. These categories are arranged in two main divisions (direct and indirect benefits), which, at the same time, fall within the realms of benefits to humans and to nature.  相似文献

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

Given the public's limited knowledge of marine environments, informing the public about marine protection presents a unique challenge. Studies have shown a well-informed public is more likely to support environmental issues and that newspapers, in particular, are considered a credible media source. This research investigates media representations of current South Australian efforts to establish a marine protected area (MPA). Articles from five newspapers between 1999 and 2006 were examined for content in the following areas: local marine ecology, the policy process of MPA establishment and stakeholder views. The research found that newspapers concentrated their reporting on opposing stakeholders, opinions and were largely ineffective in conveying the significance of the local marine ecology, the economic benefits of the MPA, and the delayed establishment process. These information gaps have left the public poorly informed, and therefore, there is unlikely to be significant pressure to overcome the continued delays in the establishment process.  相似文献

Marine protected areas (MPAs) are a global conservation and management tool to enhance the resilience of linked social-ecological systems with the aim of conserving biodiversity and providing ecosystem services for sustainable use. However, MPAs implemented worldwide include a large variety of zoning and management schemes from single to multiple-zoning and from no-take to multiple-use areas. The current IUCN categorisation of MPAs is based on management objectives which many times have a significant mismatch to regulations causing a strong uncertainty when evaluating global MPAs effectiveness. A novel global classification system for MPAs based on regulations of uses as an alternative or complementing the current IUCN system of categories is presented. Scores for uses weighted by their potential impact on biodiversity were built. Each zone within a MPA was scored and an MPA index integrates the zone scores. This system classifies MPAs as well as each MPA zone individually, is globally applicable and unambiguously discriminates the impacts of uses.  相似文献

The introduction of marine protected areas (MPAs) in Australia has resulted in an increase in the number and total area of ‘no-take’ zones. The resulting closures impact all forms of commercial and recreational fishing in and around them despite international recognition indicating that Australian fisheries were already well managed according to ecological sustainable development guidelines. Furthermore, it is recognised within Australia that most MPAs are not designed to provide protection from the full suite of known threats that can affect biodiversity and long-term ecosystem viability. By directing MPA management disproportionately towards comprehensive no-take zones that affect fishing practices that are already required by state and federal legislation to adhere to sustainability requirements, the suite of threats affecting both protected and unprotected areas can be left inadequately and/or inappropriately managed. It is shown in this paper that the modified definition of the Precautionary Principle, which was developed specifically for the MPA process in Australia, is not in keeping with accepted international definitions and guidelines for the use of precaution. It is argued that the development of a definition of precaution to justify a predetermined output (MPAs) devalues the sound use of scientific principles and diminishes the conservation outcome. Furthermore, by distracting efforts from determining and managing the full suite of recognised threats, the value of what protection is provided in Australia's marine protected areas is eroded further.  相似文献

Despite increasing attention paid to the value of marine resources, in particular marine protected areas (MPAs), their economic valuation focuses mainly on use values of ecosystem services such as fishery and tourism. Furthermore, most MPA related studies are carried out for coastal ecosystems, especially tropical coral reefs. The valuation of remote marine ecosystems is rare. The main objective of this paper is to estimate public willingness to pay (WTP) for alternative management regimes of a network of offshore MPAs in the North Sea under the Marine Strategy Framework Directive (MSFD). In a baseline valuation study carried out just before the adoption of the MSFD, beach visitors and a random sample of coastal and non-coastal residents were asked for their preferences for two alternative management options of three remote, ecologically sensitive areas with multiple use conflicts. Despite the lack of public awareness and familiarity with the offshore marine areas, a majority of 70% is willing to pay extra tax for their protection. Using a conservative value elicitation procedure, Dutch households are willing to pay on average maximum 0.25% of their annual disposable income to ban access and economic use. This serves as an indicator of what a network of remote MPAs in the MSFD is allowed to cost according to the Dutch tax payer.  相似文献

The absence of properly identified mechanisms to adequately protect the marine environment remains a major shortcoming in Australia’s commitment to biodiversity conservation. The current commitment to a National Representative System of Marine Protected Areas (NRSMPA) falls far short of providing adequate protection against the suite of existing and potential threats even though areas are designated as being ‘protected’. In this paper it is argued that the actions taken under the NRSMPA are disproportionately concentrated on regulating fishing, including the closing of areas in so-called sanctuary zones to all types of fishing. In the absence of clearly identified threats from most forms of fishing and without assessment of how best to manage those few fishing threats that have been identified, such actions are inefficient and mostly inappropriate. Moreover, they do not provide adequate protection against the full suite of threats to marine environments. Adequate measures for the proper conservation of these areas and/or the protection of marine biodiversity more generally are not being provided and in most cases threats are not even adequately described and evaluated.  相似文献

With over 30 years’ experience of managing Marine Protected Areas (MPAs), China has established more than 250 MPAs in its coastal and marine areas, but the overall management effectiveness is unimpressive [46]. Recently, China has made commitments to expand the MPA coverage in its waters ([7,52,53]) and develop an “ecological barrier” along the coast by connecting MPAs and islands by 2020 (The State Council 2015). In this context, this study reviews major challenges in current MPA practices in China, including the lack of systematic and scientific approaches, inadequate laws and regulations, ineffective governance mechanisms, conflicts between conservation and exploitation, limited funding, and inadequate monitoring programs. Four scenarios for developing China's MPA networks are developed and analyzed based on a literature review of experience in the United States, Canada, Australia, New Zealand, the European Union and the Philippines, as well as a set of interviews with Chinese MPA experts. These scenarios include: 1) creating a national system with an inventory of MPAs, 2) developing social networks, 3) developing regional ecological networks, and 4) developing a national representative network. The first two scenarios focus on the enhancement of the governance system through connecting individual MPAs as a social, institutional, and learning network, which could provide opportunities for creating an ecologically coherent network, while the latter two emphasized ecological connectivity and representativeness. Given different focuses, they can be applied at different stages of implementation and combinations of scenarios can be used depending on China's needs.  相似文献

I welcome the contribution by Harris to the ongoing debates around the Chagos Islands. He presents the complex tangle of issues with some clarity and relative balance that is often absent from many contributions on this subject.However, marrying scientific and political issues as Harris sets out to do is less helpful in this instance than distinguishing between the two. Blurring these boundaries can risk the future of the Chagos Marine Preservation Area (MPA) and the invaluable protection it affords the many species (including important food species) now thriving in the Chagos Archipelago. CCT works to study and protect this unique environment, and we would like to make some important distinctions clear.  相似文献

Since the 1980s, there have been continuous increases in the coverage of marine protected areas (MPAs) in China, and a total of 158 MPAs have been declared. The MPA system in China is characterized by (1) decentralised designation and management with reduced control from the central government; (2) a dominance of de jure fully protected MPAs that are often implemented as de facto multiple-use areas; and (3) a lack of objective evaluation processes. To improve China's MPA system requires an appropriate integration of fully protected and multiple-use MPAs, and an approach that balances the advantages of top-down and bottom-up approaches.  相似文献

Groupers are highly targeted and vulnerable reef fishes. The effects of fishing pressure on the density of three reef fishes were investigated in 21 islands outside (n=15) and inside (n=6) a Marine Protected Area (MPA) at the Paraty Bay, Brazilian southeastern coast. Two valued groupers (Epinephelus marginatus and Mycteroperca acutirostris) and a non-target grunt (Haemulon aurolineatum) were studied. The total biomass of fish caught in each island was considered as a measure of current fishing pressure, while the island distance from the villages was considered as a measure of past fishing pressure. Fish densities were recordedin number and biomass. The biomass of M. acutirostris was inversely related to current fishing pressure, which did not affect the other two fishes. The density of E. marginatus increased with the island distance from one of the fishing villages, which indicated that past fishing may have had decreased the abundance of E. marginatus. Densities of the three fishes and fishing pressure did not differ between islands inside and outside the MPA. Data on fishing pressure, densities of groupers and coral cover were combined here to assign conservation scores to islands. A redefinition of MPA boundaries to reconcile fish conservation, fishing activities and fishers’ food security was proposed.  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 statutory closure of 60 square miles of Lyme Bay to towed fishing gear in 2008 marked the culmination of nearly 20 years of discussions between conservationists and fishermen. Prior to the 2008 decision, voluntary, bottom-up led agreements resulted in inadequate protection of the bay's biological resources and significant erosion of social capital. Lyme Bay provides an excellent case study of the challenges likely to be posed by wider stakeholder involvement imposed under the new Marine Act. This paper examines a broad range of perspectives in relation to the Lyme Bay consultation and subsequent closure, via semi-structured interviews with 25 representatives of different interest groups in Lyme Bay. All respondents acknowledged significant flaws in the process leading to the Lyme Bay decision and felt the Marine Act was well placed to tackle many of these criticisms. However, while the Marine Act should provide a framework for resolving conflicts, it will not prevent them. Success will depend on collaboration between different marine interests, and also on the government acknowledging that outcomes are unlikely to favour everyone in the short-term and that top-down interventions are inevitable.  相似文献
