Marine reserves are increasingly being established as a mechanism to protect marine biodiversity and sensitive habitats. As well as providing conservation benefits, marine reserves provide benefits to recreational scuba divers who dive within the reserve, as well as to recreational and commercial fishers outside the reserve through spill-over effects. To ensure benefits are being realised, management of marine reserves requires ongoing monitoring and surveillance. These are not costless, and many marine reserve managers impose an entry fee. In some countries, dive tourism is major income source to coastal industries, and a concern is that high entry fees may dissuade divers. In this paper, the price elasticity of demand for dive tourism in three countries in South East Asia – Indonesia, Thailand and Malaysia – is estimated using a travel-cost model. From the model, the total non-market use value associated with diving in the area is estimated to be in the order of US$4.5 billion a year. The price elasticity of demand in the region is highly inelastic, such that increasing the cost of diving through a management levy would have little impact on total diver numbers. 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

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

Thorough comprehension of the perceptions of offshore Marine Protected Areas (MPAs) by different local social actors is lacking, especially in developing countries. This study aims to analyze the perceptions and socioeconomic characteristics of divers and artisanal fishers of an offshore MPA, located in Brazilian waters. Data on the perceptions, conflicts, and management of the MPA were gathered through questionnaires and interviews with local actors. The results show that scuba divers and fishers consider the MPA to be very important for biodiversity. They also consider their collaboration in participative management to be of considerable importance, even though they do not form part of the administration. For local actors, the area helps foster the preservation of the marine environment and benefits recreational diving, tourism, and artisanal fishery in local communities. Divers and fishers use the resources and space of the offshore area differently, which results in diverging perceptions and conflicts. Divers propose restricted protection (No-Take Zones), while fishers propose that the MPA should be used exclusively by the poor local communities for artisanal fishing. Conflicts arising from inefficient public administration (lack of environmental zoning, management plans, and participative management) and illegal use of the MPA were also identified. Data stemming from the local actors themselves are central to reducing the conflicts and improving public policies on offshore marine conservation. 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

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

Compared to the Pacific Ocean, tsunamis are rare both in the Atlantic and Indian Oceans. However, the December 26, 2004, tsunami demonstrated that, no matter how rare they may be, when a major tsunami occurs, it could be very disastrous. The most basic information in tsunami warning center requires are charts showing tsunami travel times to various locations around the rim of the ocean. With this in mind, a tsunami travel time atlas for the Atlantic Ocean is in preparation. The Caribbean Sea is also included in this Atlas, as it is more or less a part of the Atlantic Basin. 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

Many developing countries are expanding their network of Marine Protected Areas (MPAs) to meet ambitious marine conservation targets set globally and to develop tourism nationally. This study explores the human dimensions of MPA planning in Mozambique by engaging local resource users in a series of structured discussions about marine resource use, pressures on marine resources, ways to address such pressures, and the potential positive and negative impacts of MPAs on the management of marine resources and livelihoods, from a community perspective. Findings show that the groups and communities interviewed are at best ambivalent towards MPAs while at the same time supporting increased government regulation, including conventional fisheries management measures. The study suggests that without significant community involvement in the choice of marine conservation tools, the drive to establish MPAs to achieve biodiversity conservation and tourism development goals may be counterproductive, at least in terms of poverty alleviation and sustainable resource use. It argues that a wider range of marine conservation approaches and tools needs to be considered in addition to MPAs, taking into consideration local views and institutional capacities. 相似文献

Scuba diving tourism has the potential to be a sustainable source of income for developing countries. Around the world, tourists pay significant amounts of money to see coral reefs or iconic, large animals such as sharks and manta rays. Scuba diving tourism is broadening and becoming increasingly popular, a novel type of scuba diving which little is known about, is muck diving. Muck diving focuses on finding rare, cryptic species that are seldom seen on coral reefs. This study investigates the value of muck diving, its participant and employee demographics and potential threats to the industry. Results indicate that muck dive tourism is worth more than USD$ 150 million annually in Indonesia and the Philippines combined. It employs over 2200 people and attracts more than 100,000 divers per year. Divers participating in muck dive tourism are experienced, well-educated, have high incomes, and are willing to pay for the protection of species crucial to the industry. Overcrowding of dive sites, pollution and conflicts with fishermen are reported as potential threats to the industry, but limited knowledge on these impacts warrants further research. This study shows that muck dive tourism is a sustainable form of nature based tourism in developing countries, particularly in areas where little or no potential for traditional coral reef scuba diving exists. 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

No-take marine protected areas (MPAs), where all fishing is prohibited, have been shown to provide benefits that include greater productivity of fish stocks due to increased densities, average sizes, and reproductive output. A critical component of this success is the effective management of MPAs to ensure that only those activities deemed permissible, are allowed to occur. As of 2008, 161 MPAs had been designated on the Pacific coast of Canada by federal, provincial or municipal authorities. The objective of this study was to discover how many of these MPAs are intended to provide full protection to habitats and species from commercial fishing and whether management measures were put in place to actualize this conservation intent. The comprehensive spatial dataset was built illustrating commercial fisheries closures and this was overlaid with MPA locations in a GIS. The majority of MPAs were designated as IUCN Strict Nature Reserve (Type Ia), Wilderness Area (Type Ib), and National Park (Type II) marine reserves, which are intended to be free from exploitation. It was found that 160 of the 161 MPAs are open to some commercial harvesting within their bounds. One small municipal MPA and portions of three other MPAs are not open to commercial harvesting. The incongruence between management intent and fisheries permitted suggests a management failure between designation of MPAs and implementation of fisheries management regulations. 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

The Triangle Trans‐Ocean Buoy Network (TRITON) project by the Japan Agency for Marine-Earth Science and Technology began with deployment in the western tropical Pacific Ocean in 1998 and has shifted to steady, long-term observations since 1999. After on-site inter-comparison with the Autonomous Temperature Line Acquisition System mooring system of the Tropical Atmosphere and Ocean (TAO) array by the National Oceanic and Atmospheric Administration, the TRITON array became the international TAO/TRITON array in 2000 as a key component of the Global Ocean and Climate Observing Systems. The TAO/TRITON array took over from the TAO array, which was developed during the Tropical Ocean and Global Atmosphere program (1985–1994), and replaced the western part of TAO with new additional real-time measurements of salinity and ocean currents. In 2001, two TRITON moorings were deployed in the eastern Indian Ocean for capturing the eastern pole of the Indian Ocean Dipole. From this initiative, the Indian Ocean Observing System (IndOOS) was designed, and the Indian Ocean mooring array (Research Moored Array for Africa–Asian–Australian Monsoon Analysis and Prediction) was developed as a key component of IndOOS. In this paper, 15 years of progress in the TRITON project in the western Pacific and eastern Indian Oceans is reviewed with regards to scientific outcomes, technological development, and collaborations with international and domestic partners. Future directions for sustainable observation in the Pacific and Indian Oceans are also discussed. 相似文献

The cooperation strategies of fisheries between Taiwanese purse seiners and Pacific Island Countries
《Marine Policy》2016
The tuna industry in the Western and Central Pacific Ocean (WCPO) is one of the most valuable fisheries in the world. Taiwan has a long fishing history and is one of the major distant water fishing nations in the surrounding area. This study aimed to review the historical cooperation structure between Taiwanese purse seiners and Pacific Island Countries (PICs). Data were collected by literature analysis and semi-standardized in-depth interviews with experts. The results showed that since 1982, the Taiwanese purse seiners have developed and signed bilateral access agreements with seven PICs under a variety of formats. The fisheries access and licensing arrangements have been transformed to a Vessel Day Scheme (VDS); as a result, the access fees have increased rapidly since 2010. Taiwanese industries have invested in facilities and share ownership with some PICs. Moreover, the Taiwanese purse seiner industries have proclaimed their willingness to follow the Western and Central Pacific Fisheries Commission conservation measures and stated that they will cooperate with PICs. They hold conservative views, however, regarding the further transfer of ownership to PICs. For the conservation of tuna resources in the WCPO, distant water fishing nations and PICs should cooperate to limit fishing capacity and ensure that the access fee benefits PICs. 相似文献

In this paper the impacts of the anomalous SST in the warm pool area of the Western Equatorial Pacific on the winter time circulation and the East Asian monsoon are studied by using the NCAR CCM. It is found that the abnormal heating in the warm pool area will change the strength and the position of the Walker Cell in the Equatorial Pacific and the anti-Walker Cell in the equatorial Indian Ocean. Both the Walker and anti-Walker Cells are strengthened. The local Hadley Cells over two hemispheres near the warm pool are also strengthened. The subtropical highs in two hemispheres become stronger and move poleward slightly. The westerly jets in the extratropical regions have similar changes as the subtropical highs. The winter monsoon in South-East Asia is weakened by the abnormal heating in the warm pool. The experiment also show that there are wave trains emanating from surrounding areas of the warm pool to the high latitudes, causing various changes in circulations and local weather. 相似文献

渔获物平均营养级（Mean trophic level of fishery landings,MTL）是目前评估人类捕捞活动影响的研究中使用最广泛的生物多样性指标之一。根据联合国粮农组织FAO提供的渔获生产统计数据,结合Fishbase提供的相关鱼种营养级数据,本文评估了1950-2010年太平洋、大西洋和印度洋各沿海国海洋渔业开发状态。研究发现,在全球三大洋75个主要捕捞国中,43个国家MTL呈显著下降趋势,发生了Pauly于1998年提出的“捕捞降低海洋食物网”现象;但是,仅16个国家MTL的下降是由于高营养级种类的衰退,而27个国家属于“捕捞沿着海洋食物网”的下降机制。此外,20个国家MTL呈恢复上升趋势,但是,该恢复上升趋势通常伴随着传统低营养级种类产量的大幅下降;在上述20个国家中,11个国家的低营养级鱼类产量呈显著下降趋势。需谨慎分析“捕捞降低海洋食物网”现象,掌握MTL的潜在变化机制。 相似文献

The declaration of exclusive economic zones (EEZs) granted coastal states sovereign rights over the marine resources in their EEZs and enabled developing coastal states to legally charge access fees to distant water fishing (DWF) nations for access to the resources in these waters. Despite the potential for economic gains, however, the ability of coastal states to benefit from the granting of sovereign rights and to ensure the sustainable use of their fisheries resources depends on how domestic fishing effort responds to the harvesting decisions of the DWF nations. We develop a stylized bioeconomic model to explore the change in fishing behavior of host and DWF nations when the two nations enter into an access agreement with varying levels of access fee. We further conduct an econometric analysis of changes in Pacific island nations’ harvesting behavior in response to the harvest decisions of DWF nations using data from the Western and Central Pacific tuna fishery. Our model results show that there is a range of variable access payment levels over which the host nation substitutes benefits from its domestic fishing activity with access payments from the DWF nation and that setting fees in this range can create a trap whereby host nations are forced to trade-off receiving a fair return to their fishery resources through access fees and retaining their own active fleet capacity. Our empirical analysis further shows a gradual shift in the way in which Pacific island host nations responded to the harvest decision of DWF nations as a result of the creation of the 200-nautical-mile EEZ. 相似文献
