Coral reef areas are threatened worldwide by growing populations, tourism development, and use of poison and dynamite in fishing in areas adjacent to the reefs. The designation of marine protected areas is one strategy for addressing these problems. Wakatobi National Park, established in Eastern Indonesia in 1996, contains approximately 50,000 ha of coral reefs and a resident population of Sama-Bajo people whose traditions and current livelihoods tie them closely to the sea. The present research, using participatory rural appraisal methods, focused upon the impact of the designation of the Marine Park on their lives and investigated the potential for public participation in park planning and management. The Wakatobi Park Management Plan does not address the needs and interests of local people. Priority should be placed on adaptation of park zoning and protection regulations to accommodate the livelihood requirements of indigenous communities.  相似文献

An assumption underlying the growing support for marine protected areas (MPAs) is that they meet conservation goals and provide economic benefits to fisheries and ecotourism. However, support for MPAs will be at risk if managers cannot assess whether various MPA objectives are being fulfilled. Current approaches to MPA management emphasize the need to evaluate performance criteria; however, there is little consensus on criteria and their evaluation. We propose a marine protected area evaluation model (MPAEM), based on and modified from a multidisciplinary approach used to assess the sustainability of fisheries, called rapid appraisal of fisheries (Rapfish). The application of the MPAEM was explored in a pilot study of 20 MPAs located in different regions of the world. Results indicate that the MPAEM can be used to evaluate MPA management effectiveness. However, the manner in which the evaluation attributes are scored and ways of engaging user groups should be explored before MPAEM can become part of the day-to-day management of MPAs.  相似文献

Scientists work with marine protected area (MPA) managers to design MPAs that will protect marine resources, maintain biodiversity, promote tourism, and enhance biological production. It has become increasingly clear that scientific input is not the only requisite for ensuring establishment of these areas. Understanding the political institutions and management systems that govern these areas is as important for establishing MPAs as understanding the natural resources in the area. Recent studies have found that the success of establishing and managing MPAs can be attributed to increased public participation in the management process. This article looks at the public's involvement in the management of the U.S. equivalent of MPAs, the National Marine Sanctuaries. In particular, Sanctuary Advisory Councils are examined as one mechanism through which the public can participate in the management of marine sanctuaries. The article concludes with comments on the evolving role of these councils in marine resource management.  相似文献

Chile has been attempting to establish a Management Area (MA) system that melds the use of marine protected areas with marine tenure. The process has brought to the fore the competing interests of various user groups: artisanal fishermen, marine science professionals, government managers, tourist developers, and the Navy. We explore the core relationships among fishermen and the ecologists and biologists whose work is essential for establishing and maintaining a MA. The MA system's creation and implementation raise the key question of whether a marine tenure system can work under the conditions imposed by the Chilean government. There is a need to recognize and reconcile contradictions in a government management model that strives simultaneously to be a conservation zone and a financially profitable co-management zone. This article examines the MA management system's fault lines in the context of Chile's political economy, and the intimate interaction of management with fishermen's cultural survival strategies.  相似文献

Kepulauan Seribu was designated as a marine protected area to promote and protect a healthy marine ecosystem and its biodiversity. However, despite numerous efforts to protect the area, the park continues to be impacted by both external and internal factors. External factors include domestic sewage, vessel traffic, industrial effluent, and urban run-off from metropolitan Jakarta. Meanwhile, internal factors include the problems created by tourism development and the impacts of the economic activities of the park's residents. The ongoing political and economic crisis in Indonesia, which has plagued the country since 1997, has amplified the pressure on the resources and on the well being of the park. This study traces and analyzes the intrinsic causes of the internal problems using a socioeconomic perspective. We suggest that alleviation of poverty and marginality of the park's residents should be prioritized, and that park management should be based on consensus building and participation of all stakeholders.  相似文献

The first attempt to implement the 1999 California Marine Life Protection Act (MLPA) to establish marine protected areas (MPAs) ended contentiously in 2002. The initial MLPA process is examined by a statutory analysis and an analysis of stakeholder network relationships and beliefs. The failure of the initial MLPA process can be understood by a combination of factors: (i) Insufficient financial support from the California State government; (ii) Unclear, unranked and inconsistent statutory objectives; (iii) The application of a science-based process that excluded affected stakeholders; (iv) Implementing officials who lacked expertise in designing and managing political processes; and (v) A community of stakeholders who were polarized into coalitions of proponents and opponents of MPAs. The article concludes by discussing limitations of its methods and analysis and by offering strategies for learning from policy failures.  相似文献

Quantifying progress in management of marine protected areas (MPAs) is crucial to marine conservation and fisheries management in the Philippines. This study compiles data on the status, occurrence, and management gaps of MPAs through coordination with multiple organizations supporting and guiding MPAs in the Philippines. MPA management effectiveness was measured using a MPA Rating System. Since 2002 the modal MPA rating levels increased from level 1 (initiated) to level 4 (sustained) in 2008/9. This upward trend is attributed to factors that promoted both the establishment and improved management of MPAs. Analysis indicated that: (1) most MPAs struggle with budgetary constraints or lack of sustainable financing and (2) overall the MPAs are being maintained and progressing with notable improvement in management despite a range of difficulties encountered during the implementation process. For MPAs in the Visayan Region for which biophysical data were available, the MPA Rating System was used to assess the effectiveness of local government capacity building on MPA coral reef health. Our results suggest that MPAs with higher ratings are likely to have better reef health conditions.  相似文献

Although the success of marine protected areas (MPAs) and associated zoning schemes is largely dependent on stakeholder acceptance and support, there have been relatively few studies examining the response of recreational stakeholders to MPA proposals. This study investigates the response of recreational boaters to a proposed MPA in British Columbia, Canada. Using a structured questionnaire (n = 543) and a focus group (n = 6), the research examines the level of support for the concept of marine zoning and identifies key factors influencing support or opposition. Results indicate that a small majority of recreational boaters support the concept of marine zoning, but that there are areas of concern that ought to be addressed as MPA implementation proceeds. Support for zoning was strongly related to perceived benefits, particularly environmental benefits. Furthermore, perceived benefits overall were found to outweigh concerns as determinants of recreational boater support for zoning. Major dimensions of opposition included perceptions of over-regulation, loss of access for boating, and mistrust of the government. A suggestion is that such concerns may be mitigated through focused communication and meaningful involvement of boaters in the zoning process.  相似文献

Young men in coastal Tanzania are often blamed for damaging marine habitats by engaging in unsustainable and destructive fishing practices, including dynamite fishing, but their perceptions have not been sufficiently documented. While marine scientists, international environmental NGOs, and activists have called attention to the destructive fishing practices’ devastating impacts, insights into the contextual factors that motivate those who engage in dynamite fishing are limited. Additionally, risk perceptions and concerns regarding the environmental impact and dangers of dynamite fishing among the youth are also understudied. This paper provides ethnographic insights into the historical and contextual factors underlying dynamite fishing in rural coastal Mtwara. It draws on ethnographic data gathered through participant observation, focus group discussions and in-depth interviews with residents from two neighboring coastal villages – one located inside a marine protected area (MPA), and another located outside the MPA’s boundary. The paper first examines the views of elderly men and women to provide the historical context of dynamite fishing in coastal Mtwara. It then juxtaposes youth perceptions regarding marine conservation and dynamite fishing in the two villages, vis-à-vis ongoing efforts to curb destructive fishing practices and to enhance marine biodiversity and ecotourism in the region. Results of the study reveal that unresolved tensions between the MPA authorities and local fishers surrounding enforcement practices and unfulfilled gear-exchange-related promises, and allegations of poor governance, are important contextual factors in the persistence of dynamite fishing. The paper concludes by articulating possible remedial measures to mitigate the tensions between youth concerns about their livelihoods, and the goals of marine biodiversity conservation as a way forward in preventing dynamite fishing.  相似文献

This article has two goals: (1) to consider the underlying semantic confusion surrounding the promotion of “social science” in the design and establishment of marine protected areas and (2) to demonstrate the successful community processes that led to the designation of Sitka, Alaska's Local Area Management Plan (LAMP) for halibut fishing in the vicinity of Sitka. Uniting a collection of diverse “social” issues creates ambiguity in actual problem solving—extensive generalization can not resolve a specific issue. The Sitka LAMP is a specific case with clear details and a traceable history of success, designed to sustain the healthy status of Sitka's local halibut resource. The development of the Sitka LAMP designation demonstrates the importance of community collaboration and exhibits methods that could potentially be modeled in other locations.  相似文献

One of the major barriers to addressing complex social–ecological issues through integrated coastal management (ICM) is a lack of intergovernmental coordination and cooperation (horizontal and vertical fragmentation). This article describes an effort to overcome the barriers to ICM in Sri Lanka by fostering intergovernmental collaboration and initiating adaptive governance to restore one town, Hikkaduwa, and its associated marine protected area (MPA) and coastal zone habitats. Administrators from 12 national and local governmental agencies that are responsible for aspects of coastal management in the town of Hikkaduwa participated in a series of formal and informal workshops and a week-long tour of ICM projects in the Philippines. Outcomes demonstrate that these informal and formal meetings, workshops, and travel experiences fostered trust, social capital, and attitudinal organizational commitment (AOC). The experiences motivated members to overcome vertical and horizontal governance fragmentation through the formation of an independent intergovernmental committee for the restoration of Hikkaduwa into a sustainable and resilient community. ICM activities undertaken by the newly formed organization suggest that internal leadership capacity, effective local–national partnerships, explicitly linked ecological–economic projects, and long-term commitment are necessary conditions for success. Overall, attainment of sustainability and resilience through successful ICM should be thought of as a journey and not a destination.  相似文献

依靠图谱和经验进行船用螺旋桨的设计已经不能适应时代的要求,运用数字化手段进行设计与制造已经成为当前的主要发展趋势。本研究创新了一种船用螺旋桨边界曲线改型方法,改型过程中通过移动导边侧约束面和随边约束面的位置来控制边界曲线的形状,从而实现螺旋桨的改型设计。通过fluent软件模拟,发现随边侧约束面沿拉伸方向的移动可以有效提高螺旋桨推进效率,最高可以达到53.2%,而导边侧约束面的移动在一个相对较小的范围内对螺旋桨效率的提高有明显的作用。因此,这种拉伸式的逆向改型方法对设计具有高效率的螺旋桨具有重要的应用价值。  相似文献
