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

Marine and coastal ecosystems – and thus the benefits they create for humans – are subject to increasing pressures and competing usages. For this reason, the European Union (EU) adopted the Marine Strategy Framework Directive (MSFD), which is to guide future maritime policy in the EU and aims at achieving or maintaining a good environmental status (GES) of European seas by 2020. To this end, the MSFD requires the development of improvement measures, which have to be assessed inter alia by examining their cost-effectiveness and by carrying out cost-benefit analysis (CBA) before their implementation. This paper investigates the applicability of environmental CBA in the marine context. It identifies and discusses problems that could hamper the environmental effectiveness of the MSFD. For example, the fact that marine ecosystem services are much less tangible than terrestrial ones implies greater challenges for the quantification of benefits for society in a marine context. One finding is that the limitations of environmental valuation methods regarding their ability to capture the whole total economic value of improvement measures are a potential source of problems, as the MSFD allows countries to disregard measures with disproportionately high costs. The trans-boundary nature of the main European seas adds to the complexity of the valuation task, e.g., due to the danger that benefits that occur outside of national territories are neglected. Moreover, the current state of knowledge on the functioning of complex marine ecosystems and the links to socio-economic impacts and human well-being seem insufficient to meet the MSFD requirements.  相似文献

Marine and coastal ecosystems face widespread degradation largely because market failure hides the economic value of the goods and services they provide. Marine protected areas (MPAs) can serve as structures that ensure the continued functioning of marine and coastal ecosystem goods and services. Yet, to be effective and sustainable, MPAs must be able to prove their economic worth and generate revenue. User-fee systems are used commonly to partially finance multi-use MPAs. This study applies contingent valuation as a method of economic valuation within an MPA in southern Mozambique. Using a payment card and questionnaire from November 2012 to April 2013, this study determined the willingness to pay (WTP) of three user groups for access to the Ponta do Ouro Partial Marine Reserve. The study also investigated the potential for the reserve to increase revenues for conservation through the implementation of a user fee for marine-based activities. Probit and ordinary least squares (OLS) regressions were used to determine the effects of various independent variables on WTP. The OLS model found income, African residency and environmental awareness to be significant factors that influenced visitors' WTP for access to the reserve. The mean WTP was R 43.75 (South African rands) per person per day. Using data supplied by the reserve management, conservative estimated annual revenues based on the implementation of this fee amount ranged between R 1.46 million and R 3.3 million.  相似文献

Quantifying the monetary value of ecosystem services (ES) provided by coastal and marine resources can help policy makers assess the trade-offs and synergies inherent in ecosystem-based management of marine and coastal environments, thus increasing the social efficiency of decision-making processes. As shown by the valuation literature, the number of coastal and marine management settings where valuation researchers have attempted to make a contribution is rising fast. However, this rise in research activity has not been matched by the increase in the use of economic valuation (EV) in the actual management of coastal and marine resources. This raises an interesting question: is EV responding to the needs of policy makers? This paper provides a comprehensive overview of the knowledge base regarding the economic values for coastal and marine ecosystems. It then discusses how to improve the uptake of ES valuation research by focussing on two core issues which are thought to be essential for more effective communication with the policy community.  相似文献

Marine protected areas (MPAs) have proliferated globally in the past three decades. However, inadequate funding often prevents these management regimes from fulfilling their missions. Managers have become increasingly aware that successful protection of marine ecosystems is dependent not only upon an understanding of their biological and physical processes, but also their associated social and economic aspects. Unfortunately, economic values associated with MPAs and the natural resources they protect are rarely considered in decision-making and policy development. This study addresses this information gap by examining scuba divers’ willingness to pay for access to quality recreational sites in the Bonaire National Marine Park, Bonaire, Netherlands Antilles. The findings indicate that the US$10 annual diver user fee in effect at the time of the study could be increased substantially without a significant adverse effect on island tourism. Depending on question format, mean willingness to pay for annual access ranged from US$61 to US$134 (2002$). All model specifications support the conclusion that doubling the US$10 user fee would have virtually no impact on visitation rates. The increased revenue generated from this sustainable financing mechanism is more than sufficient to fund both current and enhanced marine park operations.  相似文献

The Marine Strategy Framework Directive (MSFD) requires EU member states (MS) to develop and implement marine strategies containing programs of measures to protect and preserve the marine environment. Prior to their implementation, impact assessments, including Cost-Benefit-Analyses (CBA), need to be carried out. While the costs of introducing such measures are often relatively easy to determine, the economic valuation of the benefits derived from environmental improvements is much more challenging, particularly in the marine context. Still, it remains an important prerequisite for conducting CBA. The aim of this paper is to evaluate to what extent benefits can be quantified for use in CBA focusing on the German marine waters. The results indicate that there are still considerable gaps in the scientific knowledge about many of the pressures mentioned in the MSFD. Moreover, few economic studies exist that evaluate the benefits of marine protection measures, and many of them are not applicable in the German context. In addition, there is the risk that some benefits accruing from marine protection measures are systematically omitted in CBA. This raises the question to what extent comprehensive CBAs as required by the MSFD are possible in Germany, but also in other EU MS.  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

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

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

Managers of marine protected areas (MPAs) are constantly challenged to encourage positive user behaviour to minimise impacts on marine ecosystems while allowing recreational use. Yet, some marine users continue to act in ways that diminish conservation values of the area. Drawing on social psychological theories, this paper presents a case for informed behaviour change strategies to reduce problem behaviours in MPAs and contribute to conservation efforts. Social psychological drivers of behaviour are explained and applied to an MPA context to demonstrate how they can inform strategies for predicting and changing behaviour using persuasive communication. As behavioural and persuasive communication theories are seldom invoked and almost never rigorously applied to MPAs, the review offers new theoretical and practical insights into how they can assist MPA management to target and shift specific behaviours that ultimately support marine park values.  相似文献

Recent international policy developments require states to conserve at least 10% of coastal and marine areas by creating effectively managed and ecologically coherent networks of protected areas in the marine environment. In the framework of the PANACHE project, the current status of designation, management and monitoring of the network of marine protected areas (MPAs) of an important environmental, social and economic marine area: the English Channel (the Channel) was examined. Currently 224 MPAs exist belonging to 12 different designation categories and covering 17 440 km2, or approximately 20.3% of the project area in the Channel. International protection targets in the marine environment are thus met at this regional scale, although the individual contributions of the UK and France are considerably different, with French MPAs accounting for nearly 80% of the total area protected. Differences between countries are also found regarding MPA designation categories (11 in France, 6 in the UK, 1 in the Channel Islands) and management structures (with more actors involved in the UK) and approach, whereas the monitoring techniques used are similar, although more standardised in the UK. Pending challenges include greater within-country and cross-country MPA designation, monitoring and management simplicity, integration and coordination as well as the assessment of management effectiveness and ecological coherence of the Channel network of MPAs.  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

Guatemala's rich coastal and marine biodiversity provides essential ecosystem goods and services to local residents and the national economy through artisanal and commercial fisheries, aquaculture, port exports and, to a lesser extent, tourism. As in many other countries, national policies emphasise the significance of marine conservation and marine resources, primarily through implementing marine protected areas (MPAs). However, this assumes that governance, as reflected in legal, institutional and organizational frameworks, political capacity and human resources is sufficiently developed to ensure MPAs meet these goals. These issues are explored through presenting the first detailed analysis of coastal and marine governance in Guatemala. The research highlights a range of barriers to good governance which restrict the extent to which MPAs can function effectively. Recommendations are made which can capitalise upon the potential for locally managed marine areas as a means to facilitate the improved governance of coastal and marine resources in Guatemala.  相似文献

This paper examines Canadians' willingness to pay to recover the populations of three marine mammal species found in the St Lawrence Estuary. The valuation approach utilized a stated preference tool that is somewhat a hybrid between contingent valuation and a choice experiment with multiple species recovery program options and choices framed as referenda. Program options involved the use of a marine protected area and restrictions on whale watching and shipping industries. The estimated willingness to pay (WTP) for different levels of marine mammal recovery ranged from $77 to $229 per year per household and varied according to the species affected and the recovery program effort. A series of tests revealed that people would be willing to pay more for programs that contribute to greater increases in marine mammal populations, but the additional value of programs that improve a species status beyond the “at risk” threshold is relatively small.  相似文献

Classifying levels of protection in Marine Protected Areas   总被引:1,自引:0,他引:1  
Marine Protected Areas (MPAs) are an important tool for the conservation of marine species and ecosystems. Yet despite the significant differences between marine and terrestrial systems in terms of their critical ecological processes, stresses, and relationships with cultural systems, methods used to characterize levels of protection for biological diversity in MPAs are all derived from schemes developed for terrestrial systems. A new system designed to classify levels of protection in MPAs is proposed, based on criteria specifically relevant to marine systems. MPAs are characterized by each of the seven criteria: designated use, quality of natural character, extent of protection throughout the year, extent of zoning into sub-areas for multiple uses, public access, extraction of resources, and size with respect to supporting critical ecological processes. Five levels of protection are defined, labeled I-V: Wilderness Management Area (Level I), Research Management Area, Ecological Management Area, Human Recreation Management Area, and Sustainable Resource Management Area (V). A level is assigned to an MPA based on the level that matches the largest number of categories across all seven criteria. The uses and benefits of this system of classification relative to existing systems are discussed and examples of its application are illustrated using data on 83 MPAs in California (USA) and 10 globally.  相似文献

The EU Marine Strategy Framework Directive (MSFD) is considered to be the environmental pillar of the EU Integrated Maritime Policy, establishing a framework within which member states must take the necessary measures to achieve, or maintain, good environmental status in their marine waters. This study presents Portugal's contributions to the Directive development, describes the Portuguese institutional framework within the MSFD and, finally, highlights the opportunities and threats to the success of the MSFD implementation in Portugal. The latter entails an analysis of the Directive's long term adequacy in its link to (1) marine spatial planning, (2) climate change and (3) the economic/financial crisis. With one of Europe's largest exclusive economic zones. Portugal's interest in the MSFD is paramount. Efforts towards the approval of the final document were assured during the Portuguese presidency of the European Council of Ministers, in 2007, while chairing a thorough discussion between the Council and the European Parliament. In the Portuguese context, the Directive implementation will rely on the Water Institute as the authoritative entity, which will be responsible for coordinating all necessary efforts at the national level. The success of such process depends on a close cooperation among the institutions involved as well as on how approved measures account for long term issues. In addition, the MSFD implementation must be built on lessons learned within the Water Framework Directive, in order to be successful. Although it poses a methodological challenge to Portugal, the MSFD implementation is expected to contribute significantly to the improvement of coastal/marine conservation and management at the national level.  相似文献

Various approaches have been used to establish marine protected areas (MPAs) in different countries. In this paper we compare and review three processes to establish MPAs within the United States and Australia. These two countries share many similarities in their cultures, but their approaches to managing marine resources differ considerably. Each of these efforts to establish or review MPAs was motivated by concern about declines of targeted marine species or habitats. However, the government actions varied because of differences in governance, planning process including public input, and the role of science. Comparing these processes highlights effective approaches for protecting marine ecosystems and gaining public support.  相似文献
