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

Coastal and marine areas the world over provide food, transportation, recreation, and energy resources to increasing numbers of people each year. As demands for these resources rise, the potential for user conflicts is radically heightened. This situation can be avoided or counteracted by instigating proactive multiple use planning. Multiple use zoning plans can only exist in a concrete management framework: marine and coastal protected areas provide just such a foundation. Nature-based or ecotourism can be encouraged in coastal protected areas aimed at achieving sustainability. Well-planned tourism provides economic and political incentives for management and for conservation, and may bring additional benefits to local communities and regional economies. Examples where nature-based tourism has been or is becoming successfully integrated into multiple use planning can be found in Quintana Roo, Mexico; the Lesser Antilles; and Australia, among other areas.  相似文献

Protected marine areas management depends mainly on the zonification schemes applied. The aim of the present work is to propose a zonification scheme for protected marine areas in the coastal zone, based on the ecosystem features. This ecosystemic zonification is based on structural and functional elements of marine ecosystems, and allows the incorporation of the main environmental characteristics into the management plan of these areas, whether information about biotic factors is available or not. Based on this, a zonification of the Sistema Arrecifal Veracruzano National Park is proposed, which considers the identification of various subsystems, seascapes and environmental units within nested scales, to be included in the national park management plan.  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 history of Korean tidal flat management and the process for designating Coastal Wetland Protected Areas (CWPAs) are described. Korean coastal wetlands have a long history of intensive use through reclamation for agricultural and industrial uses in the 20th century. Recently, the management policy is shifting away from intensive use towards the conservation of wetlands. This shift is caused by increasing public awareness of the value of wetlands and strong institutional support from the government. Since the Wetlands Conservation Act was passed in 1999, a total of twelve CWPAs have been designated through both top-down and bottom-up processes. Three designation paths are classified based on the relevant drivers, namely government-driven designations (seven CWPAs), local community driven designations (three CWPAs), and conflict resolution (trade-offs) driven designation (two CWPAs). The lessons learned from the designation of Korean CWPAs is that diversification of designation process could facilitate voluntary participation of local stakeholders and thereby enhance the chance of successful implementation of wise use strategy of tidal flats.  相似文献

A general conceptual framework for the management of marine protected areas (MPAs) was developed. The driver-pressure-state-impacts-response (DPSIR) framework was used to determine the elements affecting MPAs. The developed evaluation framework helped to select an appropriate suite of indicators to support an ecosystem approach, an assessment of the MPAs functioning and policy decisions. Gaps derived from the management and policy responses in the MPAs were also outlined. It was concluded that the DPSIR framework can help to simplify the complexity of MPA management. This document is a tool for policy makers, scientists and general public on the relevance of indicators to monitor changes and MPAs management.  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

Australian flora and fauna are both highly endemic and species-rich, yet they have been under enormous human pressure as ecosystems have been simplified and fragmented. In order to promote biodiversity Australia has ratified the Convention on Biological Diversity (CBD) and has released a Draft National Strategy for the Conservation of Australia's Biological Diversity. The purpose of this article is to explore how Australian biological diversity will be supported in a national system of marine protected areas. Attention is given firstly to the international and Australian responses to biological diversity, particularly with respect to the use of in situ conservation. This is followed by an overview of the Australian marine protected area system. An assessment is made on how marine protected areas can further conserve and enhance the unique biodiversity of Australia.  相似文献

Management of the Belize Barrier Reef was originally envisioned through the creation of marine protected areas. However, the influence of land-based activities was not accounted for in Marine Protected Area (MPA) programs. Therefore focus was shifted to an integrated approach via Integrated Coastal Management (ICM). The Belize ICM process has evolved into a system of coordination through the fostering of multi-sectoral linkages for integrated management of coastal resources. Marine protected areas were included in the ICM program as tools for achieving biodiversity protection and management of sensitive habitats. The ICM process has resulted in greater coordination and consultation in decision making for coastal resource issues, the MPA program however has not evolved with the trend of greater community involvement in MPA management. The greatest challenges to MPA and ICM programs in the next 10 years are: improved linkages between the two, fostering of community participation in management, broadening of the scope of ICM to watersheds and ocean governance, and sustainable financing for both programs.  相似文献

A comparison of three marine protected areas in Indonesia illustrates many of the problems in management planning and implementation. Major factors influencing management are proximity to urban areas, the protected area's economic potential, current uses and the resolution of jurisdictional disputes. Isolation does not prevent resource depletion. Improving the economic conditions of local residents and gaining their commitment to environmentally sustainable commercial and subsistence resource uses within and near protected areas are vital to implementing area management.  相似文献

While the recurrent cost of managing marine protected areas (MPAs) has been documented and estimated, there has been virtually no attempt to quantify the cost of establishing MPAs in the first place. This lack of attention is likely the result of the complexity of the process, involving often uncoordinated efforts of a multitude of governmental and non-governmental entities over a protracted period of time with no clear start and end-point. Using information gathered from a representative subset of MPAs worldwide, this paper presents the first attempt to identify and describe the various components, and explore potential predictors of the total funds spent in the course of establishment. The thirteen MPAs studied vary in size (from <1 to >360,000 km2), location (including near- and offshore in both developed and developing countries), objectives and degree of protection. Variation in MPA start-up costs is shown to be most significantly related to both MPA size and the duration of the establishment phase. Development of a method to estimate the potential cost of establishing proposed MPAs should play a crucial role in the conservation planning process.  相似文献

In coastal zones, natural protected areas have been created without considering the relationship between the two environments they involve. This is currently a crucial challenge for conservation efforts, because the protection initiatives taken in coastal watersheds need to be integrated with the marine component. With the aim of contributing to increase the knowledge in this issue, the present work analyzes the current state of conservation efforts in the Mexican coastal zone, based on a simplified theoretical approach focusing the coastal zones as a group of ecotones functionally connected by the flow of matter end energy. We found that only 16 of 92 Mexican coastal watersheds have natural protected areas in all the ecotones analyzed, whereas 15 of them lack of any kind of protection. The present investigation may facilitate the appraisal of gaps in watersheds and coastal ecotones conservation management, with emphasis on the connectivity between marine and terrestrial environments of the coastal zone.  相似文献

Much of the research that concerns the impacts of management measures in the eastern Baltic cod fishery has focused on fish stock rather than understanding fishermen's attitudes towards regulations. Hence, there is little information available on fishermen's responses although they are the ones whom the regulations affect most profoundly. This study analyses the views of fishermen towards management measures with an emphasis on fishing closures (marine protected areas, MPAs). Swedish log-book data from 1996 to 2005 were used to describe MPA induced fishing effort displacements. Fishermen argued that MPAs have been inefficient in conservation of cod stock. The enlargement of Bornholm MPA in 2005 caused substantial effort displacement towards areas dominated by smaller sized fish. This contributed to the increased discarding of juvenile cod. Enlarged MPAs also intensified competition between different fleet segments and reallocated fishing areas. To reduce fishing mortality, fishermen suggested days-at-sea (effort) regulation and an effective landings control system for all fleets that exploit cod stocks in the Baltic Sea Main Basin. These measures would better motivate fishermen for mutual rule compliance, which is a prerequisite for a sustainable cod fishery.  相似文献

Citizen science monitoring programs in the marine environment frequently focus on volunteer collected data precision for conservation and resource use of marine biota. Few studies have examined the social science aspects of volunteer engagement in marine monitoring programs in a quantifiable manner. This research focuses on emotional attitudes of Sea Search volunteers who monitor Marine National Parks and Marine Sanctuaries in Victoria, Australia. Volunteers responded that their participation in Sea Search activities made them feel good emotionally and mentally, with active learning, such as remembering names of marine biota, stimulating brain activity and memory. Volunteer monitoring efforts generated personal satisfaction through their contributions, feelings of enjoyment, and socialising with others. Sea Search volunteers gain a sense of want to protect and conserve the marine environment through positive behaviour change. By understanding and having a sense of meaning towards the marine environment, the volunteers felt a sense of pride in themselves. The concepts of volunteer connection to the natural environment and positive mental and emotional health are important for any citizen science monitoring program and should be used in the program’s aims and strategies as an effective means to attract volunteers. A functional framework which clearly communicates and assesses not only the scientific expectations from a citizen science program, but also the health and wellbeing connections to nature, need to be addressed in Government marine and coastal strategies.  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

The marine angiosperms Thalassia testudinum, Syringodium filiforme, and Halodule wrightii form two of the largest reported seagrass beds along the northwest and southern coasts of Florida where they cover about 3000 square km in the Big Bend area and about 5500 square km in Florida Bay, respectively. Most of the leaf biomass in the Big Bend area and outer Florida Bay was composed of Thalassia testudinum and Syringodium filiforme which were distributed throughout the beds but which were more abundant in shallow depths. A short-leaved form of Halodule wrightii grew in monotypic stands in shallow water near the inner edges of the beds, while Halophila decipiens and a longer-leaved variety of H. wrightii grew scattered throughout the beds, in monotypic stands near the outer edges of the beds, and in deeper water outside the beds. Halophila engelmanni was observed scattered at various depths throughout the seagrass beds and in monospecific patches in deep water outside the northern bed. Ruppia maritima grew primarily in brackish water around river mouths. The cross-shelf limits of the two major seagrass beds are controlled nearshore by increased water turbidity and lower salinity around river mouths and off-shore by light penetration to depths which receive 10% or more of sea surface photosynthetically active radiation. Seagrasses form large beds only along low energy reaches of the coast. The Florida Bay seagrass bed contained about twice the short-shoot density of both Thalassia testudinum and Syringodium filiforme, for data averaged over all depths, and about four times the average short-shoot density of both species in shallow water compared with the Big Bend seagrass bed. The differences in average seagrass abundance between Florida Bay and the Big Bend area may be a consequence of the effects of greater seasonal solar radiation and water temperature fluctuations experienced by plants in the northern bed, which lies at the northern distribution limit for American Tropical seagrasses.  相似文献

Conflict surrounding commercial fisheries is a common phenomenon when diverse stakeholders are involved. Harvesting reef fish for the global ornamental fish trade has provoked conflict since the late 1970s in the State of Hawaii. Two decades later the state of Hawaii established a network of marine protected areas (MPAs) on the west coast of the island of Hawaii (“West Hawaii”) to protect and enhance the fish resources and alleviate conflict between stakeholders, principally between commercial dive tour operators and aquarium fishers. The perceptions held by these stakeholders on West Hawaii and Maui were evaluated to understand how MPAs influenced conflict dimensions, as the former location had a well-established MPA network designed to alleviate conflict, while the latter did not. This was accomplished by analyzing the following questions: (1) perceptions about the effectiveness of MPAs to alleviate conflict and enhance reef fish; (2) perceived group encounters and threats to coral reefs; (3) willingness to encourage fishing; and (4) value orientations toward the aquarium fish trade. The results indicate the MPAs in West Hawaii were moderately effective for alleviating conflict, encounters between stakeholders occurred on both islands, dive operators strongly opposed commercial fishing and perceived aquarium fishing as a serious threat to the coral reef ecosystem, and polarized value orientations toward the aquarium fish trade confirms pervasive social values conflict. The conflict between these groups was also asymmetrical. MPAs are inadequate for resolving long term conflict between groups who hold highly dissimilar value orientations toward the use of marine resources. Future marine spatial planning and MPA setting processes should include stakeholder value and conflict assessments to avoid and manage tensions between competing user groups.  相似文献
