Legal Regulation of Land Reclamation in China's Coastal Areas

China's national marine development strategy acknowledges that land reclamation problems cannot be avoided. Land reclamation has increased rapidly, leading to many risks—as regards resources, the environment, and social concerns. China needs to implement measures to control these risks. Analysis of current legal regulations on land reclamation reveals paradoxes of legislation at the national level and varying regional legal practices; there is a shortage of effective and coordinated land reclamation regulations in China. Analysis of the factors that affect land reclamation shows that regulation plays a central role in managing land reclamation. And, through an analysis of the deficiencies in existing legislation and by learning from the experience of other countries, we can propose a direction for China's land reclamation legislation. Such reforms could effectively protect China's marine resources, avoid environmental and societal risks, and contribute to coastline protection.     

Abrolhos 2000 : Conserving the Southern Atlantic's Richest Coastal Biodiversity into the Next Century

The Abrolhos bank, an area of continental shelf off the coast of Bahia, Brazil, has the most biologically diverse coral reefs in the entire southern Atlantic Ocean. The coral reefs and nearby coastal ecosystems constitute a global conservation priority and are the target of the Abrolhos 2000 project, initiated by Conservation International as part of its global marine conservation strategy. Although portions of the Abrolhos reefs are located within a marine park, they are not afforded adequate protection due to insufficient conservation resources and a failure to be part of a broader integrated coastal management program. Through partnerships with government agencies, nongovernmental organizations, local communities, the private sector, and other stakeholders, Abrolhos 2000 is working to provide these needs while establishing local capacity for conserving coastal and marine ecosystems. The project's initial successes provide examples of useful strategies for making integrated coastal management work in the context of emerging economies.     

Sanctuary Advisory Councils: Involving the Public in the National Marine Sanctuary Program

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.     

Exploring Public Knowledge,Attitudes, and Perceptions of the Marianas Trench Marine National Monument

With the increase in development of large marine protected areas (LMPAs) worldwide, there have been calls from social scientists to gather better empirical information about the human dimensions of LMPAs. Of the social research done on LMPAs to date, most has focused on the perceptions of stakeholders closely connected to their implementation, and little research has explored the general public's response. This paper presents the results of a phone survey conducted in the US territories of Guam and the Commonwealth of the Northern Mariana Islands to assess residents' knowledge, attitudes, and perceptions of the Marianas Trench Marine National Monument—a LMPA designated offshore in 2009. The survey was administered in 2012 to 500 randomly-selected residents from each territory. Findings suggest: (1) public awareness of the Monument prior to the survey was low; (2) residents generally supported designation of the Monument; (3) most residents did not believe that the Monument would affect them or their community; and (4) knowledge and perceptions of the Monument varied between fishing and non-fishing households. This research illustrates that awareness and views differ between stakeholders and those of the general public, which should be used to inform social research on LMPAs and outreach for LMPA managers.     

Integrated Marine Planning for Cocos (Keeling), An Isolated Australian Atoll (Indian Ocean)

The Cocos (Keeling) Islands are located on an isolated atoll in the Indian Ocean and have a strong Malay culture owing to the translocation of a substantial plantation workforce in the early 19th century. The atoll became one of Australia's External Territories in 1955. Meeting the marine resource needs of the atoll residents within an Australian legislative system by formulating an integrated marine management plan presented several challenges. Key factors in drafting a culturally meaningful plan were a commitment to understanding and accommodating the cultural and subsistence needs of the community, innovative communication strategies, and a simple approach to management. Development of the plan highlighted the limitations of current Australian marine planning legislation in cross-cultural settings and for sustainable development.     

An Overview of Spatial Management and Marine Protected Areas in the East China Sea

Marine ecosystems of the East China Sea are rich in biodiversity, with 12,933 species of which approximately 47.7% are endemic. As anthropogenic impacts are intensifying, fishery resources and biodiversity in the East China Sea are under threat from overfishing, habitat loss, pollution, and biological invasions. Marine protected areas (MPAs) and other spatial management measures are believed useful tools to protect and restore biological resources. Seventeen nature reserves, seven special marine reserves, and three fishery resource conservation zones covering a combined area of 102,156 km² have so far been established in the Chinese East China Sea in order to protect fishery resources, biodiversity, and marine landscapes. This article provides a review and inventory of MPAs in the Chinese East China Sea as implemented by the People's Republic of China.     

Examining Residents’ Proximity,Recreational Use,and Perceptions Regarding Proposed Aquaculture Development

Competing interests related to marine resources have the potential to create conflict in the coastal zone. In many parts of the world marine farms exist in close proximity to areas that support recreation and tourism. The purpose of this study was to examine residents’ perceptions of proposed marine farm development related to their proximity to, and recreational use of, a coastal area in New Zealand. Residents from two areas were surveyed about their recreational use of the region and about perceptions related to marine farm development. Results indicated that those living closest to proposed marine farms used the area more often and in different ways, were most sensitive to marine farm development, and were less positive in their evaluations of marine farms, despite agreeing that marine farms can have positive economic consequences for nearby communities. Implications for using stakeholder input for the planning and management of marine farms are discussed.     

Community Participation in Marine Protected Area Management: Wakatobi National Park,Sulawesi, Indonesia

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.

User Fee System for Marine Ecotourism: The Tubbataha Reef Experience

The Tubbataha Reefs Natural Marine Park, a UNESCO World Heritage Site in the Sulu Sea, Philippines, is an offshore marine protected area well known throughout the scuba diving community for its coral reefs and marine diversity. To address the perennial problem of park financing, the Tubbataha Management Board developed a fee collection and permit system in cooperation with the diving community. A willingness-to-pay survey conducted among divers in 1999 showed that the average diver was willing to pay U.S.$41 per visit. Using these results, a two-tiered pricing scheme was developed for foreign and local divers. After two years of fee collection, the total fee collected amounted to U.S.$65,000, which covered 28% of the annual recurring costs and nearly 41% of the core costs to protect Tubbataha. The experience shows the contribution of willingness-to-pay surveys in instituting user fees for long-term sustainable financing.     

A numerical study on the installation configuration design of compliant vertical access riser (CVAR) in deepwater

In oil and gas transportation, the compliant vertical access riser (CVAR) system conducts economic and operational advantages due to its special configuration. In this paper, the static performance of the CVAR is studied by an efficient numerical method. According to the unique configuration of the CVAR, the mathematical model is established based on minimum total potential energy principle. The equilibrium equations are discretized by finite difference method and then solved by Newton-Raphson technique. The accuracy of the numerical method is verified by OrcaFlex software. Detailed parametric analysis is carried out based on practical engineering requirements. The effects of buoyancy section's configuration including buoyancy factor, buoyancy section's length and buoyancy section's location, and external environmental factors including wellhead offset distance, water depth and current velocity on installation shape and mechanical properties of the CVAR are analyzed. The research shows that the presented numerical method has good applicability and flexibility for the early installation configuration design of marine risers which have no touchdown section but only one touchdown point and are equipped with multiple buoyancy blocks subjected to forces of different directions and magnitudes, such as CVARs.     

Competing Visions for Marine Tenure and Co-Management: Genesis of a Marine Management Area System in Chile

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.     

Applying the Value-Belief-Norm Theory to Marine Contexts: Implications for Encouraging Pro-Environmental Behavior

Encouraging pro-environmental behavior among protected area visitors and other stakeholders has become a priority for marine resource managers. However, there exists a lack of understanding of the human dimensions of resource management regarding the perceptions and attitudes of stakeholders. Using the value-belief-norm theory of environmentalism (VBN) as a framework, the purposes of this investigation were to: 1) test a model of variables that influence stakeholders' intentions to adopt pro-environmental behavior in two marine protected areas (i.e., the Great Barrier Reef Marine Park and the Florida Keys National Marine Sanctuary); and 2) using the relevant literature and information gleaned from the model, suggest techniques that managers can use to encourage pro-environmental intentions. Acceptable goodness-of-fit indices for both of the structural equation models (one for each protected area) provided empirical support for the usefulness of the VBN framework to guide both research in marine contexts and marine protected area management efforts to encourage stakeholders' intentions to engage in pro-environmental behavior. Specific suggestions include increasing stakeholders. knowledge about impacts via environmental education strategies, increasing their awareness of their impacts and their efficacy in mitigating those impacts (e.g., workshops), and developing interpersonal relationships among managers and stakeholders (e.g., implementation intention and follow-up strategies).     

Sea Cucumber Moratorium and Livelihood Diversity in Papua New Guinea

Livelihood diversity factors such as flexibility within fisheries, geographical mobility, reallocation of fishing effort into the broader economy, and the non-material benefits that fisheries provide are important areas of research in marine policy. We use two small-scale fisheries related socio-economic surveys of communities in the Tigak Islands of Papua New Guinea. The first conducted 5 years before a ban on the harvesting of sea cucumbers was imposed and the second from the present day, 5 years after the initiation of the ban—with the objectives of exploring changes in household fishing strategies (types and numbers of species targeted) and to identify any important socioeconomic factors that help explain those changes. Fishing's contribution to total household income has increased significantly (p = 0.019) up from 61% in 2004 to 73% in 2014 with the percentage of female residents living in a household now positively and significantly (p = 0.018) associated with fishing income. The average number of species categories targeted per household increased insignificantly while households with more women are significantly (p = 0.018) less likely to target more species than households with more men. Moreover, customary management practices contribute to this difference. Together, these results show that households are not worse off financially 5 years after the ban on sea cucumber harvesting and that gendered seascape use has implications for the role of livelihood diversity as a marine policy tool.     

Assessing economic activity in coastal areas: A shift‐share approach

Abstract

An essential aspect of economic analysis associated with planning efforts is identifying the composition of existing economic activity and understanding historical trends in economic change. The shift‐share model is a useful and inexpensive tool for this purpose. Shift‐share analysis evaluates changes in local economic activities relative to changes in a reference area (usually the state or nation). Economic change is separated into a reference area component, an industry mix component, and a local share component. These measure, respectively, the effect on the local economy due to changes in the reference area, factors specific to the local mix of industries, and the changing competitive position of the local area relative to the reference area.

A shift‐share analysis of Florida's coastal counties reveals that all grew much faster over the 1965–1975 period than did the national economy. This rapid growth is primarily a result of a net shift of economic activity toward the study area relative to the nation. However, a few coastal counties did exhibit a mix of slow‐growing industries. Specific industry results for Florida counties at the eighty‐industry level reveal that many industries showed significant shifts toward Florida's coastal counties. The performance of individual industries in the coastal counties generally exceeded that of the same industries in noncoastal counties.     

Dynamite Fishing in a Marine Protected Area in Tanzania: Why Youth Perceptions Matter

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.     

Risk zone of wrack hitting marine structure simulated by 2D hydraulic model

The wrack or the ship out of control will drift with flow.One of the most important factors that drive the ship is flow current which moves circularly in tidal area.The wrack from same place always drifts in different ways if the start time is different.So,during the ship drifting period,the drift trace is also determined by both wave and wind forces.The drift direction is limited by water depth which must be deeper than ship draft. These marine structures that can not afford the hit of wrack or will destroy the wrack must be well considered when they are placed near harbor and waterway or other water area with ship running.The risk zone should be consulted according to tide and weather conditions to protect structures and ships in necessary.A method is presented here to simulate the risk zone by 2D numerical hydraulic model with tidal current,wave,wind and water depth considered.This model can be used to built early-warning and protect system for special marine structure.     

Looking Beyond Cargo and Cruise Ships: Promoting Academic Marine Research and Clean Technologies as an Economic Development Strategy for Ports

The Port of Los Angeles (Port) is the largest container port in the Western Hemisphere, and a catalyst for business activity and employment. Historically, the majority of the Port's workforce lived in the communities directly adjacent to the Port. However, in the latter half of the last century, jobs and economic activity began to shift away from the Port, causing public attitudes in the local communities to change. Instead of being viewed as the source of their livelihood, local residents began to view the port as a generator of environmental impacts and industrial blight. Formidable community opposition to Port growth and modernization ensued. Employment within the Port district peaked in the mid 20th century at 100,000. By 2009, the Port had only 12,700 jobs. To re-establish and maintain a long-term positive relationship between the Port and its neighbors, the Port needed to increase the numbers of local residents in the port on a daily basis. The Port looked beyond its traditional role of cargo handling, to leverage creation of new water-dependent job clusters. The strategy incorporates elements of the traditional cluster concept by proposing to co-locate and create synergies between technology developers, university researchers, and marine and maritime industries.
