Abstract

Presently, much of Israel's 190‐kilometer‐long Mediterranean coast is either unoccupied, devoted to unsuitable uses, or is in use by activities which have no special need to be near the water's edge. This has resulted from years of lack of appreciation by policy‐makers of the coast as a valuable resource, of national development policies that directed attention to other regions, and of the relatively limited demand for coastal recreation.

In the last decade the importance of these factors has diminished. In turn, there is now mounting pressure for the development of coastal land. Increasingly, rising standards of living with a greater demand for recreational facilities, the growth of tourism as a major industry, and demands of the environmental lobby for conservation of part of the coastal land are factors bound to cause intensive change along the coast and to affect the quality of its resources. These trends have brought about public intervention in deciding the future of the coast. This paper reviews and analyzes Israel's coastal policy and its resource management programs, and also discusses the potential challenges to their full implementation.

Three types of programs were suggested as the main management tools: a coastal research and development effort, national coastal land use planning and pollution prevention, and monitoring and control programs. Major objectives of the programs were to be achieved through land use controls. Consequently, an important role is given in the development and implementation of the coastal program to agencies responsible for the management of physical land use planning and development.

Successful implementation of the management program, however, will depend on the ability of its administrators to coordinate the actions of many interests, on success in changing attitudes among decision‐makers as to the value of the coast, and on widening support for coastal resource conservation among a presently uninvolved public.  相似文献

The welfare of the marine environment of the U.S. West Coast of California, Oregon, and Washington is hindered by insufficient understanding of ecosystem dynamics and human pressures. Greater coordination, integration, and support of mutually identified research priorities across research organizations on the West Coast are necessary. This level of collaboration is essential to responding to regional ecosystem threats, such as the impacts of human occupation of coastal areas, over-harvesting of marine resources, and climate change. To address this need for collaboration and build on the accomplishments of existing research organizations, this article advocates the establishment of a West Coast regional marine research program (RMRP).  相似文献

Abstract

The purpose of this article is to describe a program of agricultural land preservation in Carlsbad, California. This program focuses on agricultural subsidies and has been adopted and certified by the California State Coastal Commission and is scheduled for implementation on January 1, 1982.

This subsidy program is a variation of development rights transfer. Although no property rights are actually transferred, owners of land designated for agricultural use are subsidized by fees imposed on land designated for potential conversion to residential use. The Carlsbad program is placed into context by means of a brief review of similar proposals which attempt to preserve agricultural land in a fair and equitable manner.

The importance of agricultural land preservation is emphasized through discussions of urban development pressure, the significance of agriculture in the Carlsbad coastal zone, and the work of the California State Coastal Commission.  相似文献

The welfare of the marine environment is threatened worldwide. In order to maintain ecosystem services management must shift from single sector to ecosystem approaches. To support this transition in marine management, this article reviews collaborative ecosystem-based management in the California Current Large Marine Ecosystem (CCLME), through an overview and comparison of three collaborations on the United States West Coast of California, Oregon, and Washington. The achievements of these collaborations are demonstrated. Networking and extending collaboration throughout the entire region is shown to be essential for environmental conservation and sustainable development in the CCLME.  相似文献

The Gulf of California hosts astounding biodiversity that supports numerous economic activities in the region. These activities, and emerging threats, are placing pressure on the region's ecosystems. Government and civil society are working to address threats through several conservation and management mechanisms. Nevertheless, the use and incorporation of scientific information—a key component for creating effective and durable management—is still deficient. This article presents the concept of science integration and discusses the findings of a study that assesses the regional landscape, existing institutional arrangements, and capacity for using science to inform policy and management decisions. It also explores the current use of science within fisheries policy and management and the capacity of the National Network of Information and Research of Fisheries and Aquaculture (RENIIPA) and the State Fisheries and Aquaculture Councils, two mechanisms in the region. Finally, it shares lessons learned and offers recommendations on how the region can strengthen science-based decision-making. Results indicate that while there are some actors in the Gulf of California producing relevant science, there is varying capacity of intermediary groups connecting producers with users of science, or mechanisms in place to ensure that science is being utilized in decision-making processes. Moreover, despite having a well-developed landscape of producers and intermediaries and mechanisms in place for fisheries management in the region, effective science integration is not occurring.  相似文献

Seaports are a vital part of the maritime transport industry and have a key role in integrated transport chains and regional economies. However, ports are also sites of environmental pollution originating from land-based activities, ship movements and ports’ own activities. It is, therefore, increasingly recognised that economic growth in ports must be balanced with environmental protection and social progress. This has led to enhanced appreciation of the need for sustainable development (SD) in ports. Whilst much has been written about port environmental practices in European and American ports, there is limited synthesis and comparison of sustainable port practices from different parts of the world. Furthermore, in-depth case analysis and critical examination of the practices and challenges of sustainable port development in a globalised era is limited. This paper presents findings from a qualitative multi-case study that aimed to compare sustainable policies and practices of ports in four different continents and to understand the dilemmas, challenges and opportunities they face in attaining SD. This paper reports findings pertaining to the following research questions: (1) What policy frameworks do ports adopt to attain sustainable development? (2) What specific sustainable practices do ports utilise to manage environmental aspects such as air pollution, water quality, ballast water, dredging and disposal of dredged materials, waste disposal, hazardous substances and land/resource use? (3) What are the driving and constraining forces in achieving sustainable development in ports? Port authorities were studied by reviewing documents and secondary data. The following ports were studied: Port of Long Beach (USA), Port of Rotterdam Authority (The Netherlands), Sydney Ports Corporation (Australia) and Transnet Limited that owns and manages South African ports. Findings of the study demonstrate that the SD paradigm has gained momentum, albeit to differing degrees, in the functioning, organisation and the very ethos of case study ports. An important theme from all case studies is that, whilst there is definite progress towards SD, several practices deemed to be sustainable can be controversial and must be critically examined from the perspectives of different stakeholders including shippers, port-related businesses and the local and global community. Lack of data to monitor environmental impacts, economic costs of implementing sustainable practices and complexities of international, regional and national regulations were other constraining factors. On the other hand, reconciling differences between stakeholders and capitalising on economic opportunities, operational efficiencies and cost savings offered by environmental friendliness can advance port SD. Public–private partnerships and policies negotiated by involving all stakeholders were found to foster port sustainability. Most importantly, this study found that, with globalisation, environmental impacts of ports are not always localised. ‘Sustainable’ practices can have unintended consequences in other parts of the world. Therefore, globalisation necessitates a more critical and global analysis of port operations and environment practices in order to be truly sustainable. Although the scope of the research findings is limited to case study ports, the lessons drawn can be constructively applied to any port operating within an institutional system of structured SD.  相似文献

Large North American ports are encountering serious management challenges. Surrounding communities, environmental interest groups, and government policy are focusing on protection and enhancement of public coastal amenities. In Vancouver, the federal port management system historically enabled national trade interests to override local and regional objectives at the discretion of port decison makers. In contrast, the Port of Seattle is administered at the local level, and legislation and policy require that local publics are involved in decision‐making. Recently, VPC established itself as the vanguard among Canada's major ports in the advancement of progressive management. Nevertheless, the adoption of new policies would ensure that Vancouver, and Canada's other ports, continue to be responsible leaders in Canadian coastal management. These policies include: federal, municipal, and provincial government representation on the local board of directors; strengthening community involvement; creation of a standing planning advisory committee; subjecting Canadian ports to the federal environmental assessment law; and adoption of explicit land and water use regulations.  相似文献

Abstract

local wastewater management policies can be important tools for protecting marine water quality when coordinated with sound land use and environmental planning. that relationship is examined through a review of the point and nonpoint source pollution issues associated with centralized versus decentralized wastewater management approaches, sewerage extension and plant expansion effects, and sewerage management practices. we use information provided by 161 local jurisdictions in coastal regions of the southeastern united states and various secondary regions of the southeastern united states and various secondary sources. the article concludes with a discussion of policy implications and recommendations to improve the coordination of local sewerage extension/expansion practices and land use planning.  相似文献

This paper emphasizes dryports in the context of port regionalization. It specifically deals with dryports as a challenge for planning, policy and metropolitan governance in the vicinity of seaports. The starting point is the ongoing spatial shift of terminals, distribution centres and port related developments towards the hinterland of mainports and the associated planning conflicts, raising negative impacts such as congestion, land consumption, land use conflicts and neighbourhood conflicts. The paper discusses these challenges against the empirical case of the Süderelbe-region in the Southern hinterland of the port of Hamburg, Germany. It focuses on the often neglected yet highly controversial issue of land use and related traffic flows. Further it reveals how these conflicts are being managed at the regional level. The main contention of the paper is that port regionalization triggers substantial planning conflicts different from those that are known from core port areas, due to the associated demand for land and infrastructure and also as a result of the often poorly developed institutional framework to solve these problems.  相似文献

Water quality trading programs allow regulated point sources to meet some nutrient control requirements by buying nutrient reduction credits from other pollutant sources. Reduction credits can be created when agricultural land managers implement best management practices and regulators predict that those practices will result in water quality conditions equivalent to controlling discharges at the regulated source. However, natural variability in runoff combines with model and data limitations to make predictions of water quality equivalence uncertain. Nutrient assimilation credits can be created by increasing the capacity of the ecosystem to assimilate nutrients through investments in aquatic plant biomass creation and harvest, shellfish aquaculture, stream restoration, and wetlands restoration and creation. Nutrient assimilation credits and agricultural nonpoint source reduction credits are evaluated based on a number of water quality criteria including service quantification certainty, temporal matching, additionality, and leakage. Nutrient assimilation credits can provide greater certainty than agricultural best management practices in producing equivalent water quality outcomes and should be an option in trading programs.  相似文献

Abstract

The Sefton Coast Management Scheme in northwest England uses an area‐based project to achieve coordinated land management. It is founded on the ‘'Heritage Coast'’ model pioneered by the Countryside Commission where a ‘"Project Officer”; is employed to promote the Scheme and translate the aims into practical achievement. The Sefton Coast is described and a summary of British coastal planning policy precedes a detailed analysis of the Scheme. The Scheme is assessed with reference to practical management work, its success in competition for scarce financial resources, and the involvement of volunteers. It is established that the Project Officer is crucial to the success of the Scheme and that area‐based management can best be achieved through the local government planning process. Coastal planning needs now to be reviewed at national level to develop a policy for the whole coast using the experience of projects such as the Sefton Coast Management Scheme.  相似文献

Estuaries are last in line as a recipient of river water and for this reason they are particularly vulnerable to negative environmental impacts due to water scarcity and pollution. They only receive the runoff that has not been abstracted or prevented from reaching rivers. When this runoff is substantially reduced their functionality is undermined and they often become less attractive for recreational use. This article explores some aspects entailed in efficiently managing the allocation of water to estuaries problem and some associated problems. It is shown that efficient management requires the marginal social costs of the inflows to be brought into equivalence with the marginal social values of the inflows, and these values may be estimated, but that there are the challenges in this estimation and in linking these estimates to the welfare of the people in whom the managers of river systems are (presumed to be) interested.  相似文献

Sea-level rise (SLR) is not just a future trend; it is occurring now in most coastal regions across the globe. It thus impacts not only long-range planning in coastal environments, but also emergency preparedness. Its inevitability and irreversibility on long time scales, in addition to its spatial non-uniformity, uncertain magnitude and timing, and capacity to drive non-stationarity in coastal flooding on planning and engineering timescales, create unique challenges for coastal risk-management decision processes. This review assesses past United States federal efforts to synthesize evolving SLR science in support of coastal risk management. In particular, it outlines the: (1) evolution in global SLR scenarios to those using a risk-based perspective that also considers low-probability but high-consequence outcomes, (2) regionalization of the global scenarios, and (3) use of probabilistic approaches. It also describes efforts to further contextualize regional scenarios by combining local mean sea-level changes with extreme water level projections. Finally, it offers perspectives on key issues relevant to the future uptake, interpretation, and application of sea-level change scenarios in decision-making. These perspectives have utility for efforts to craft standards and guidance for preparedness and resilience measures to reduce the risk of coastal flooding and other impacts related to SLR.  相似文献

Abstract

Catch share programs are used in fisheries management to meet goals such as species recovery, overcapacity reduction, and economic efficiency. Anticipated impacts include fleet consolidation, infrastructure reduction, and social disruption within communities. The Pacific Coast Groundfish Fishery Social Study (PCGFSS) aims to understand social changes related to the recently implemented West Coast Groundfish Trawl Catch Share Program. In this article, we use a subset of PCGFSS data to explore the ways remaining fishery participants have thus far adapted to catch shares. While some vessels have left the fishery, we found that many participants are adapting to this catch shares program despite challenges. Quota leasing strategies, fishery diversification, gear innovation, and community quota funds are some of the tools participants are using to continue operating under the catch shares program. These early challenges and adaptations to the catch share program are worthy of continued tracking, as researchers, managers, and fishing communities, would benefit by considering first-hand perspectives of the on-the-ground realities of harvesting groundfish in the rationalized fishery.  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

The coastal zone is an interaction region between land and ocean and an interface of geosphere, hydrosphere, atmosphere, and biosphere, as well as greatly affected by human activities. Driven by economic activities and increased population, urbanization is rapidly developing in coastal zones, and a series of land resource and environmental conflicts have occurred, especially in developing countries at times of economic transition. This article reports a case study of the Shandong Peninsula of East China. We analyze the land-use practices and land cover changes of six cities over a timeframe of nearly a decade. We then review the management conflict issues. The most commonly encountered conflicts fall into three categories: those between expanding constructed land and decreased cultivated land; those between land resource utilization and conservation; and those between increasing demand for land and degrading land quality. All in all, they reflect the fundamental conflicts between short-term economic development gains and long-term food security and ecosystem sustainability. This article puts forward an institutional approach to coordinate these conflicts so as to realize integrated and coordinated coastal management.  相似文献
