It is generally accepted that stakeholders, including resource users, scientists, conservationists, government and nongovernment organizations, and the general public, can contribute positively to management processes and may even benefit from such processes. However, we continue to struggle with how to design processes that effectively involve these stakeholders. To illuminate potential improvements to traditional processes, this study examines participants’ perceptions of coastal and marine resource management processes. Through semi-structured interviews, respondents describe how they feel about various elements of participatory processes. Responses offer insight into the multiple dimensions of participatory process elements described in the literature, such as influence on decisions, exchange of information, access to the process, transparent decision making, and others. Responses also identify additional elements that have received limited attention in the public-participation literature: hosting meetings at various scales, recognizing differences within interest groups, and considering the context of a process. Results from this study will help to inform the design of participatory coastal and marine resource management processes.  相似文献

Dangerous marine stingers (jellyfish) are an emotive issue in tropical Australia, where they are widely regarded as the number one marine health threat. However, numerous severe and fatal stings have been reported throughout the tropical and temperate seas of the world, indicating that marine stingers are a global health problem. Further, life-threatening jellyfish stings are more frequently reported globally now compared to earlier decades, possibly as a result of improved recognition and reporting, or increased spatial and/or temporal distribution or densities. As stinging incidents may also have significant financial implications (lost tourism revenues and liability settlements), and the treatment of envenomed patients comes at high cost to the taxpayer, this issue is also a management challenge. This article outlines suggested approaches, based largely on Australian experience, for dealing with this under-recognized global coastal management issue.  相似文献

This article provides results on the net benefits generated from the natural resources in the Bohol Marine Triangle (BMT) in the Philippines. The BMT spans over 112,000 ha and its coastal ecosystems are rich in biodiversity and provide economic opportunities to the coastal communities. With a 10% discount rate, the accumulated total net benefits for the BMT resources over a 10-year period is US$11.54 million. Tourism and the municipal fisheries are the most important direct use values of the coastal and marine resources of the BMT accounting for 44% and 39% of the total net benefits. Annual revenues attributed to ecosystems were as follows: coral reefs, US$1.26 million; beach/intertidal area, US$1.12 million; marine waters, US$646,501; mangrove, US$239,561; and seagrass, US$105,990. The large market values indicate the dependence of the local community on the BMT coastal and marine resources. In the same way, non-market values show the important life-support functions of coastal and marine ecosystems. The net benefits reflect the magnitude of potential losses due to improper management of coastal and marine resources in the BMT. This valuation highlights the importance of the coastal services to the BMT economy and draws attention to the benefits the local stakeholders derive from BMT coastal resources. Policy measures can now take into account these values to justify a sufficient investment in coastal management efforts to sustain the flow of coastal services in the interest of current and future generations.  相似文献

This article provides a brief introduction to the theme issue on “The role of geography in contemporary coastal management policy and practice.” The theme is addressed through a suite of seven articles that collectively consider how geographical understandings and methods relate to contemporary coastal policy and practice. The key theme to emerge from the articles is that geography forms an underlying framework for considering integrated coastal management, largely due to the integrative nature of geography itself.  相似文献

Coastal erosion is a serious problem that affects the safety and livelihoods of many coastal dwellers along Ghana's coast. Despite the fact that coastal erosion is a natural phenomenon, erosion trends have been largely aggravated by human-induced factors. This study analyzed shoreline change rates for three neighbouring coastal communities in the Central region of Ghana; Elmina, Cape Coast and Moree. Two epochs were analyzed, 1974–2012 (medium-term) and 2005–2012 (short-term), using ArcGIS and Digital Shoreline Analysis System. Overall, the entire study area recorded average shoreline change rates of ?1.24 myear?1 and ?0.85 myear?1 in the medium-term and short-term period respectively. Less consolidated shoreline segments recorded higher erosion rates in both periods while cliffs and rocky segments experienced very little erosion or high stability. Because shorelines undergoing chronic erosion do not fully recover after short-term erosion events such as storms, facilities located close to such shorelines are threatened. Taking a proactive approach to coastal erosion management, such as coastal sand mining prevention, inter-sectoral land use management and adopting a construction setback approach may be prudent for the long-term management of the coast since this recognizes future shoreline changes and safeguards coastal landscape for other uses.  相似文献

It is a fact that coastal zones in the Mediterranean are becoming progressively more seriously degraded. Instrumental to the phenomenon in Spain is the evident failure of the coastal management that the institutions have pursued for over three decades, both under the old, state-centralized model, and the new organizational model with the political division of land into autonomous regions. This failure can in part be explained not only by the inadequate tools the administration possesses to address the dynamism and complexity of the new economic activities that have sprung up along the coast, but also by incoherent sectoral policies. Finally, there has been no all-encompassing political strategy capable of dealing with coastal communities' demands for development and the need for the protection of ecosystems and their natural resources. All this has resulted not only in a deterioration of the area, but also in the discrediting of actions implemented by the institutions, and their plans and programs being perceived as an obstacle to economic development.  相似文献

Four decades ago Australia was credited as being an early leader in implementing integrated coastal management (ICM). Nevertheless, as a federation of states and territories Australia has since struggled to fully implement vertical integration of its coastal governance arrangements. In particular the federal government has historically possessed only a minor role in coastal management despite the recommendations of several major inquires suggesting that this role needed to be enhanced. This article examines a series of circumstances and events over the past two years in Australia that has created the opportunity for the federal government to adopt a more significant and prominent role in coastal management and hence to substantially complete the vertical integration of ICM in Australia. These stimuli for coastal policy reform could also play a role in enhancing ICM in other federated nations.  相似文献

Access to current, comprehensive, and reliable spatial information is necessary for informed decision making in integrated coastal and ocean management. This need is being met through development of a marine spatial information infrastructure that encompasses both technological and institutional responses. This article traces Canada's experience in developing a marine spatial information infrastructure over the last 30 years starting with the compilation of coastal atlases, through the development of geographic information systems, to remote data acquisition instruments and Web mapping portals. Because of the plethora of initiatives, it has been essential to be selected and limit the number and choice of examples. The institutional response has lagged behind that of technological innovation and hinges on understanding users’ needs and decision support drivers, sustainability of institutional and individual champions, and, above all, cooperation and collaboration among the broad community of practice.  相似文献

Abstract

This paper is written in response to a recent publication (Walker, 1973) which questions both the biological basis for wetlands preservation and the usefulnesss of scientific participation in the formulation of management policies. Our major points are that: (1) considerable evidence exists linking wetlands primary production to aquatic secondary production, (2) all available information suggests that large‐scale wetlands destruction results in lowered production of estuarine organisms of interest to man, (3) more than economics needs to be considered in attempts to analyze the procedures by which the wetlands controversy is to be resolved, and (4) uncertainty about the applicability of scientific findings to a particular problem situation does not destroy the usefulness of those findings in reaching a solution to a public controversy.  相似文献

In 1991 the Philippine government shifted many coastal management responsibilities to local governments and fostered increased local participation in the management of coastal resources. In their delivery of integrated coastal management (ICM) as a basic service, many local governments have achieved increasing public awareness of coastal resource management (CRM) issues. Continuing challenges are financial sustainability, inadequate capacities, weak law enforcement, and lack of integrated and collaborative efforts. To address these challenges, a CRM certification system was developed to improve strategies and promote incentives for local governments to support ICM. This system is being applied by an increasing number of local governments to guide the development and implementation of ICM in their jurisdiction. The CRM benchmarks required for a local government to achieve the first level of certification are: budget allocated, CRM related organizations formed and active, CRM plan developed and adopted, shoreline management initiated and two or more best practices implemented. Implementation is providing tangible benefits to communities through enhanced fisheries production associated with MPAs, revenues from user fees and enhanced community pride through learning exchanges and involvement in decisions, among others.  相似文献

Climate change is predicted to have particularly challenging impacts throughout the Arctic. For instance, there is a great probability of sea ice melting, leading to increased vessel traffic and oil pollution. Eight major nation-states have vested concerns in the potential opening of Arctic sea routes. They each have pledged to take protective action through the Arctic Council. However, there is still a need to develop an international institution to simultaneously address Arctic marine pollution and protect the needs of these states. This article seeks to design a legally binding regime for oil pollution control in the Arctic. In creating this new regime, we shall utilize several shared design elements of historically effective international regimes and take advantage of the legal innovations of these agreements. Our new regime, entitled the Arctic Shipping and Environmental Management Agreement (ASEMA), will take into account both the economic and environmental interests of the parties involved.  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

The study develops a model of recreational fish catch probabilities, based on angler fishing strategies, that is conditional on uncertain information about the coastal ocean environment. We calculate expected catch based on a hypothetical Baseline Data Set and hypothetical data from an Integrated Ocean Observation System (IOOS) to demonstrate potential benefits from IOOS. The role of Bayesian probabilities in Random Utility Models of recreational fishing is identified. The study discusses the types of information that will be required by recreational anglers in the Gulf of Mexico. Results have implications for the construction of ocean observation systems for recreational fishermen.  相似文献
