Abstract

This article argues that using the public sector and the private market in the historically delineated and traditional ways offers only the bluntest of tools with which to approach the complex problem of coastal zone management. It therefore seeks to provide a basis for reformulating our understanding of sectoral responsibility with regard to resources management. First, it conceptually analyzes the relative strengths and weaknesses of the two sectors. Second, it examines three examples of coastal resources management—beaches and shorelands, artificial reefs, and coastal wetlands—in analyzing the complexities of the coastal management challenge and the limitations of our current approaches. Finally, we provide an alternative perspective on how these common property resource allocation decisions can be made.  相似文献

A strategy to revitalize coastal shipping within Great Britain is investigated. An examination of the regulatory environment shows government, at both the EU and British levels, aware of the environmental benefits of coastal shipping compared to road freight transport, if only mildly supportive in tangible terms. The geography of Great Britain and the modern preference for just-in-time deliveries have severely restricted the ability of coastal shipping to compete effectively with road freight transport. The primary objective of the paper is to investigate whether coastal shipping could be integrated into a multimodal door-to-door supply chain, where it is currently hampered by high costs of transhipment, slow transport speeds, and the incongruity of load sizes between land and sea modes. Integration requires the co-operation of all organizations within the multi-modal supply chain. However, coastal shipping companies have been known to be individualistic and mistrusting of alliances. Therefore, a Delphi study is undertaken to investigate the standpoint of leading managers in such companies towards multimodal integration. The results of the Delphi study indicate that managers are in favour of multimodal developments, in particular cooperation between coastal shipping and road haulage. However, there was agreement that the business is highly competitive, and this may prevent the forms of collaboration required for multimodal systems. The secretive nature of the coastal shipping sector could impede joint marketing to promote a mode of transport that is often ‘invisible’ to shippers. There was little consensus on the relationship that should exist between coastal shipping and ports, a topic worthy of further investigation.  相似文献

This article examines the use of inland mined sand and offshore dredged sand for beach nourishment projects in North Carolina, focusing on the question of whether inland mined sand is economically preferential for hot‐spot erosion control. Excavation, processing, and transport costs are presented, and cost efficiencies of hypothetical beach nourishment projects are compared. Cost analyses indicate that inland mined sand is economical for small projects (10,000–50,000 cubic yards), given that a clean sand source can be located within 15 miles of the nourishment site. The two factors primarily influencing per cubic yard costs of inland sand are overland transportation expenses and processing costs. The use of dredged offshore sand is less expensive for large projects (> 100,000 cubic yards) due to the economies of scale affecting dredge mobilization. Large beach nourishment projects in North Carolina will most likely continue to utilize offshore dredged sand.  相似文献

This paper reviews a number of themes that have played a crucial role in the debate on alternative contracting regimes for the provision of urban bus services. We have selected four crucial issues to reflect on: (i) contractual regimes (in particular competitive tendering as compared to negotiated performance-based contracts, as means to award the rights to provide service); (ii) contract completeness (focussing on ex ante and ex post elements); (iii) building trust through partnership; and (iv) tactical or system level planning for bus services. Experience in these areas suggests that competitive tendering has frequently not lived up to expectations and that negotiation is likely in many circumstances to deliver better value for money.  相似文献

The topic of social inclusion is now maturing in the Thredbo conference series, being viewed as an important consideration in many aspects of land transport, the benefits extending beyond the socially excluded targeted population. The social inclusion workshop included presentations on new empirical evidence on the value of providing those at risk of social exclusion with mobility options, and how this links to improvements in personal wellbeing, often through mediating influences such as social capital. Work was presented on the role of transport services specifically targeted to those at risk of exclusion, particularly taxi services and school bus services, as well as how to modify fare structures to maximise inclusion in an efficient, mature transport system. The value of Universal Design principles to groups both at risk of being excluded as well as the current travelling public, was shown. The workshop affirmed the importance of including these wider benefits of inclusion in cost-benefit evaluations of transport. The issue of how best to move knowledge into strategic and operational policy, and the transferability of both knowledge and policy between different countries and settings, was discussed. This paper concludes with suggestions arising from the workshop in relation to policy and research, as well as recommendations for Thredbo 12.  相似文献

Social policy makers rarely associate the ability to be mobile with having a role in the facilitation of social inclusion. This paper provides an initial exploration of the association between a person’s travel patterns and their risk of social exclusion. Information is drawn from a major Australian Research Council transport study which interviewed 535 people from Metropolitan Melbourne, Australia. It includes an analysis of the extent of the person’s bonding and bridging social networks, their connectedness to the community, self-assessed level of well-being and their beliefs about whether or not they are able to control outcomes in their life. It was found that those who had the greatest risk of social exclusion, travelled less often and less distance, owned fewer cars and used public transport less, than those who were more socially included. However, those who were more at risk of social exclusion did not identify their lower trips as due to either a lack of transport, or problems with the public transport system. The ability to have good bridging networks appears to be related to increased trip-making and promotion of social inclusion but not necessarily self-assessed well-being which is satisfied by bonding networks.  相似文献

This paper focuses on recent experiences in the evolution of Flexible Transport Services (FTS). It describes how previous manifestations of FTS provided dedicated solutions for special groups, often in parallel to the conventional public transport network, but highlights that in numerous countries across Europe there is now a discernable trend towards open access FTS providing services for the whole community and often feeding the conventional public transport network to provide wider access and opportunities. This is as a result of policies intended to mainstream services for people with disabilities and moves to tackle social exclusion amongst other groups while at the same time reducing the very high costs per trip associated with STS.To meet these policies, and the higher expectations and different travel behaviours of citizens to-day, it is suggested that FTS will need to radically reposition itself in terms of scale, so that there is mass coverage and ability to function as a full transport mode. This will require breakthroughs in concepts; business models; organisational and operational models; and in supporting technologies. A proposed solution to this is the Flexible Agency for Collective Mobility Services (FAMS) which provides an organisational structure and business model for FTS that incorporates the required supporting technologies.  相似文献

The job satisfaction level (JSL) of self-employed container truck drivers (SCTDs) is vital to the container trucking industry’s (CTI) stability in China. An anonymous field survey of 645 SCTDs was conducted at Shanghai Port. Three ordered probit models were, respectively, developed to analyze the drivers’ JSLs, their attitudes, and reactions to a CTI downturn. This study contributes to the literature that the demographic variables were not statistically significant for the SCTDs’ current JSLs, while higher income SCTDs with fewer expenses were expected to have higher JSLs. During an industry downturn, drivers with families in Shanghai showed more job dissatisfaction. More working hours, lower income, expensive diesel fuel, a high consumer price index (CPI), and a low freight-to-distance ratio (FDR) significantly lowered the JSLs. An increase in the price of diesel fuel and the CPI, and a lower FDR exposed the industry to risk and instability. Additionally, credible evidence indicated that as the dissatisfaction levels of SCTDs rise in a downturn, SCTDs implement more practical measures that may negatively affect the industry’s stability as well as society’s. Based on these findings, managerial or policy implications were proposed to efficiently improve SCTDs’ JSLs and CTI stability in Shanghai.  相似文献

Munich, Berlin, Hamburg, Vienna, and Zurich – the largest cities in Germany, Austria, and Switzerland – have significantly reduced the car share of trips over the past 25 years in spite of high motorisation rates. The key to their success has been a coordinated package of mutually reinforcing transport and land-use policies that have made car use slower, less convenient, and more costly, while increasing the safety, convenience, and feasibility of walking, cycling, and public transport. The mix of policies implemented in each city has been somewhat different. The German cities have done far more to promote cycling, while Zurich and Vienna offer more public transport service per capita at lower fares. All five of the cities have implemented roughly the same policies to promote walking, foster compact mixed-use development, and discourage car use. Of the car-restrictive policies, parking management has been by far the most important. The five case study cities demonstrate that it is possible to reduce car dependence even in affluent societies with high levels of car ownership and high expectations for quality of travel.  相似文献
