This paper reviews the research to date that relates to the economics of marine protected areas (MPAs). A special effort is made to examine the evidence on the benefits and costs of MPAs in terms of consumptive and nonconsumptive marine resource interests. General observations are made regarding the net effects of MPAs on these two stakeholder categories and the potential institutional costs of MPA implementation are highlighted. In general, the review finds that the empirical research on the economics of MPAs is limited and that there are several issues that might merit further investigation. The researchable topics are suggested as a way to better understand the socioeconomic impacts of MPAs and the potential response of stakeholders to proposed protected areas.  相似文献

Various international treaty bodies and non-governmental organisations continuously urge States to establish a network of Marine Protected Areas (MPAs) in areas beyond the limits of national jurisdiction (ABNJ). Although this goal is far from being reached, the OSPAR Convention may serve as an example illustrating the efforts made on a regional level for the North-East Atlantic. However, these efforts to effectively protect the marine environment are subject to limitations under the Convention on the Law of the Sea (UNCLOS). Likewise, the OSPAR Convention itself restricts the scope of such protected areas. The OSPAR Convention does not adequately cover all human uses of the oceans that may interfere with a protected area, and it lacks opportunities for internationalised enforcement measures. Consequently, the responsibility for effective conservation measures under the OSPAR model ultimately remains with individual Contracting Parties, i.e. their commitment to set stricter standards and to agree on their enforcement. Nevertheless, ‘soft’ obligations such as reporting duties are suitable for collecting data on the need for protection and utilisation of the MPAs. Additionally, cooperation with regional fisheries management bodies allows for better protection of the living resources in these areas. Finally, OSPAR MPAs can draw attention to particularly vulnerable ecosystems and promote conservation standards and measures such as those developed under the auspices of the FAO.  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

The development of seawater desalination plants to increase water reliability in coastal areas poses a threat to the health of near shore marine ecosystems and may affect the effectiveness of marine protected areas (MPAs) that have been established to meet international conservation targets. This paper applies a multi-criteria analysis approach to quantify stakeholder groups’ priorities for seawater desalination plants that have been proposed in communities adjacent to a National Marine Sanctuary. All groups placed the highest importance on minimizing environmental impacts on protected areas and endangered species that could be affected by water intake and brine discharge emphasizing the need for integrated land and sea conservation. Minimizing socio-economic impacts on coastal communities was much less important. Stakeholders also weighted reducing pressure on water levels in rivers, streams, and aquifers as more important than increasing water for residential consumption, which may foster coastal growth rather than replacing water taken from other sources. The study further revealed differences in the importance of multiple management objectives among stakeholder groups, which highlights the need to elicit distinct priorities of all groups to understand concerns and potential conflicts of desalination with existing marine users. The analysis of consistency ratios revealed that around half of all surveyed stakeholders had high inconsistencies in their responses, which suggests either a lack of understanding of desalination, or reflects the complexity of establishing desalination plants in coastal areas adjacent to a marine protected area.  相似文献

In order to enable effective management of marine protected areas (MPAs), desired MPA achievements need to be identified as early as possible for the development of relevant and clear management goals, objectives and conservation targets. As the definition of MPA success is a social construct, the involvement of multiple groups in this process including government agencies, stakeholders, and other interested parties is increasingly advocated. This study investigates diverse groups’ opinions on the performance of a proposed National Marine Conservation Area (NMCA) on the West coast of Canada prior to its establishment. In order to analyse and quantify the importance of MPA performance criteria among multiple stakeholder groups, the Analytical Hierarchy Process (AHP) is applied. Findings reveal that marine stakeholder groups have distinct preferences for future MPA performance. Most differences are obvious between user and non-user groups. The study also finds that respondents’ characteristics other than stakeholder groups affiliations influence expectations towards the proposed MPA including livelihood dependency on the marine environment, amount of time spent in the area, and engagement in fishing activities.  相似文献

An assessment of management effectiveness of Kenya's oldest marine protected areas (Malindi and Watamu) was conducted within the framework of a regional assessment in Kenya, Seychelles and Tanzania. Biophysical, socio-economic and governance indicators were used to assess the delivery of MPA management objectives. Results indicate that the Malindi and Watamu marine parks that are no-take areas are making progress towards meeting their stated objective of biodiversity conservation. The 1997–1998 ENSO related bleaching event caused the greatest single measurable impact on the coral reefs of the marine parks leading to very high levels of coral mortality. The marine reserve where fishing is regulated was less effective in meeting its objective of sustaining community livelihoods. The weakest trends were related to the development of governance structures. A combination of management inefficiencies due to overlapping mandates, financial and administrative constraints, and inadequate stakeholder participation interacted to reduce the ability of the MPAs to fully achieve their objectives.  相似文献

Systematic planning for conservation is highly regarded but relies on spatially explicit data that are lacking in many areas of conservation concern. The decision support tool Marxan is applied to a reef system in the central Philippines where 30 marine protected areas (MPAs) have been established in communities without much use of biophysical data. The intent was to explore how Marxan might assist with the legally required expansion to protect 15% of marine waters, and how existing MPAs might affect that process. Results show that biophysical information alone did not provide much guidance in identifying patterns of conservation importance in areas where the data are poor. Socioeconomic data were needed to distinguish among possible areas for protection; but here, as elsewhere in marine environments, the availability of such data was very limited. In the final analysis, local knowledge and integrated understanding of socioeconomic realities may offer the best spatially explicit information. The 30 existing MPAs, which encompassed a small proportion of the reef system, did not limit future options in developing a suite of MPAs on a broader scale. Rather, they appeared to generate the support for MPAs that is obligatory for any larger zoning effort. In summary, establishing MPAs based on community-driven criteria has biological and social value, but efforts should be made to collect ecological and socioeconomic data to guide the continued creation of MPAs.  相似文献

The primary role of marine protected areas (MPAs) is marine conservation, however policy and practice around MPAs have not reflected this. The focus on cost-effectiveness by spatial conservation prioritization has led to a bias towards placing MPAs in areas that are least threatened. This study investigates how conservation priorities differ between two management strategies of either targeting or avoiding high threat areas for protection, using the case of the Sulu Sulawesi Seas in the Coral Triangle. For both strategies, the target of protecting 20% of habitat could not be achieved solely by protecting low threat areas. A high proportion of the region had large differences in conservation outcomes between the two strategies; majority of these areas were highly prioritized in the threat avoidance strategy but had low or zero importance in the threat selection strategy. Selecting for highly threatened areas required less habitat area to be protected to achieve the same conservation target and resulted in a more equitable distribution of priority sites per country and sub-region. This demonstrates the importance of deciding on the objectives of conservation and management policies up-front. The results suggest that, contrary to the common practice of avoiding threats in spatial planning, a threat selection strategy should be part of the management toolbox, particularly in transboundary planning for regions with high overall threat levels, where it may be important to achieve shared conservation targets equitably.  相似文献

Many conservationists and local governments in the Philippines (and other tropical countries) have attempted to link marine protected areas (MPAs) with dive tourism, arguing that the user fees generated by dive tourism can potentially generate satisfactory outcomes for all stakeholders. In this paper, an account of the relationship between MPAs, dive tourism and small-scale fisheries in the Calamianes Islands, Philippines, is presented. It is argued that although the assumed harmonious relationship between marine conservation and dive tourism may work in theory, in practice different understandings of MPAs can create conflict.  相似文献

Regional efforts have increased the number and amount of marine protected areas (MPAs) in the Caribbean, yet few studies have examined how these MPAs are progressing toward their goals and objectives. Using social and ecological data from a rapid assessment of 31 MPAs and their associated human communities in the wider Caribbean, this study investigates (1) the stated social and ecological objectives of MPAs; (2) the extent to which MPAs are making progress toward their stated social and ecological objectives; and (3) tradeoffs in progress toward social and ecological objectives. Findings indicate that Caribbean MPAs have multiple objectives related to both social and ecological conditions, and that most MPAs are making at least some progress towards achieving these objectives. Those MPAs with stated objectives to promote education and serve as a model for other MPAs seem to be making good progress on these objectives, while those with the objective of reducing conflict are not. Where MPAs are not meeting their goals and objectives, planners and managers should consider reallocating human and financial resources to address deficiencies and re-evaluating existing goals and objectives. It is important to consider how existing marine protected areas are performing as efforts in the Caribbean region and elsewhere continue to promote the establishment of new MPAs.  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

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

Historically, martial law in Taiwan severely restricted access to and use of coastal areas. Since the martial law was lifted in 1987, the government has permitted more than 80 development projects in coastal areas throughout Taiwan. However, rapid growth and overexploitation have led to significant degradation of oceanic and coastal environments. To protect and sustain marine ecosystem functions, species, and habitats, proactive conservation measures are needed. One of the most effective measures is the establishment of marine protected areas (MPAs). In this paper, we introduce the current situation of protected areas in Taiwan. We then discuss the general concepts of MPAs, describe the characteristics of Chinwan in the Penghu archipelago, and conclude with lessons learned from the attempt to establish an MPA at Chinwan.  相似文献

Dudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization of protected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced by the new regulation-based classification system [11]. Here we clarify that we do not advocate replacing the current IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and the new regulation-based classification when applied to MPAs. With an increasing number of MPA types being implemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socioeconomic benefits is key for advancing conservation targets and policy objectives. Although the IUCN categories can be used both in terrestrial and marine systems, they were not designed to follow a gradient of impacts and there is often a mismatch between stated objectives and implemented regulations. The new regulation-based classification system addresses these problems by linking impacts of activities in marine systems with MPA and zone classes in a simple and globally applicable way. Applying both the IUCN categories and the regulation-based classes will increase transparency when assessing marine conservation goals.  相似文献

The social dimensions of marine protected areas (MPAs) play an important role in MPA success, yet these social dimensions are little understood. We explore the social impacts arising from the establishment of an MPA using Lyme Bay (south west England) as a case study. Through a series of small group semi-structured interviews the social impacts experienced by fishermen (mobile and static gear), recreational users (divers and sea anglers) and recreation service providers (charter boat and dive businesses) were explored. The social impacts expressed varied according to activity in which the stakeholder group engaged. Negative themes included lengthening fishing trips, tension and conflict, fishermen identity, equity and uncertainty in the long-term. Positive themes included improved experiences for both commercial fishermen and recreational users, and expectations for long-term benefits. These impacts need to be understood because they influence stakeholder behaviour. Failure to interpret stakeholder responses may lead to poor decision-making and worsening stakeholder relations. These findings have implications for the success of the MPA in Lyme Bay, but also for the future network of marine conservation zones around the UK. Any assessment of MPA impacts must therefore identify social as well as economic and environmental change.  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

Terrestrial reserves and national parks have taken many forms and they continue to be directed toward variable and often imprecisely defined outcomes. A prominent contemporary focus is to pursue the continuance of biodiversity. To this aim the concept of protecting comprehensive, effectively managed and representative areas from overt development, such as urban sprawl and agriculture, has been globally adopted. Within Australia ‘effectively managed’, has been replaced by ‘adequate’, a poorly defined term which is interpreted optimistically and combined with ‘comprehensive’ and ‘representative’ to create the CAR principle. This principle was first developed within the Australian forestry sector to guide management in addressing a very specific threat to a clearly identified component of biodiversity in limited and well defined areas; the preservation of declining stands of some tree species within limited old growth forests. Even though the CAR principle is central to Australia's process of developing a network of marine protected areas (MPAs) its relevance to marine systems has not been demonstrated. Its efficacy for the conservation of marine environments is questioned. The uncritical transposition of terrestrial management paradigms, including the CAR principle, to the marine realm has misled marine management. It is argued that disproportionate commitment to terrestrial principles, including CAR, and unjustified advocacy for MPAs generally have biased public perception and management efforts to the detriment of effective marine conservation and sustainable use of marine resources.  相似文献

If managed in isolation, coastal and marine protected areas (MPAs) are vulnerable to natural resource development and exploitation occurring outside these areas—in particular, overfishing, alteration and destruction of habitats, and water pollution. Thus, protection of coastal and marine areas—of species, habitats, landscapes, and seascapes—should be integrated into spatial development strategies for larger areas, under the umbrella of integrated coastal and ocean management (ICM). This is typically easier said than done, since the actors involved in MPA networks and in ICM programs are often different, reflecting different cultures, networks of relationships, ministries, and goals and motivations.This article reviews the ecological, social and economic linkages between MPAs and the governance of broader ocean and coastal areas; sets forth nine guiding principles for managing MPAs within an ICM context; reviews work conducted under the Convention on Biological Diversity to operationalize the linkages between ICM and MPAs; and develops strategic guidance for addressing these linkages. The article ends with a call to bring together the diverse communities involved in marine protected areas, coastal and ocean management, and watershed management to collaborate in national-level ocean and coastal planning, including in the designation of networks of marine protected areas.  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

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
