Upstream pollution sources and coastal water quality protection in North Carolina

Abstract

A watershed‐based approach to water quality management is necessary for protecting coastal water quality, but the relative importance of inland pollution sources on estuaries is often overestimated. This can lead to a misallocation of coastal water protection resources and ignorance of coastal zone pollution sources. This overestimation of upstream contributions is attributable to a failure to recognize that many estuaries have little or no inland drainage area, the confusion of basinwide pollutant loading with pollutant delivery to estuaries, the low delivery ratios for many pollutants within drainage basins, and disproportionately high pollutant delivery for sources within the coastal zone. Examples are given from North Carolina. As a general rule, resources expended on pollution control within or near the coastal zone will result in more coastal water quality improvement per unit effort than resources expended upstream.     

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.     

Towards a theoretical model for behavioural adaptations to changes in the road transport system

A preliminary theoretical model is developed for the mechanism of behavioural adaptations to changes in the road transport system, which describes the process of behavioural change, explains the nature of adaptation phenomenon, and predicts its effects on road safety programmes. It can be used as a basis to organize the body of adaptation research and to explain empirical results.     

Organization and planning of ambulance transport services in England and Wales

The ambulance service is the largest special needs transport operator in England and Wales and an important pillar of support to the National Health Service. In the last decade its size and role as a transport agency have been the subject of at least two government‐inspired reviews which have questioned the efficiency of the ambulance service and examined in some detail its operational performance. The ambulance service also faces constraints on its funding, like the rest of the health service, which raises questions as to its ability in the future to meet all patient demands for transport, especially in the area of non‐emergency outpatient services. The organization of the ambulance service is described from a number of perspectives: historical, institutional and managerial. These suggest that changes occurring in the approach to health care and management which are based on assumptions of cost‐effectiveness and competition, will likewise affect the organization and provision of patient transport services. The ambulance service may become an even more specialist operator competing or co‐operating in certain areas of work with other transport agencies especially in the area of non‐emergency outpatient services. Scenarios are outlined on how this may be achieved and the likely implications for the delivery of health care.     

Competition and Ownership in Land Passenger Transport: The Sixth International Conference,Cape Town,South Africa,September 1999 - Part 2

This paper presents an overview of some recent developments in and policy issues relating to integrated transport systems in the European Union (EU). Both goods and passenger transport systems are considered in the context of actions recently undertaken and supported by the EU. The paper considers the very general background of these systems at the EU scale and offers insights into some recent successful and promising policy, real-life, and research attainments. In addition, it attempts to identify some directions for future actions in fields such as transport policy, transport technology, transport economics and transport scenarios.     

The MEPLAN models of Bilbao,Leeds and Dortmund

A trio of closely related land‐use/transport interaction models was developed using Marcial Echenique & Partners’ software package MEPLAN. The models were for the cities of Bilbao, (Spain), Dortmund (West Germany) and Leeds (England). All were calibrated using data drawn from earlier studies. The three models were used to predict the effects (relative to a base case) of a common programme of land‐use and transport policies or scenarios. This paper explains briefly the theoretical basis of the MEPLAN package as applied to urban models such as these three; describes the types of policies that have been assessed; and presents some of the key results.     

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.     

Maritime commercial malpractices and piracy under international law

The term ‘Piracy’ tends to be used in a loose, popular sense to refer to various acts of violence or lawlessness at sea which are not, strictly speaking, acts of piracy in law. In this article, the author examines the concept of piracy under international law and related notions such as hijacking and mutiny. In this context, he shows that the ‘malpractices’ of robber bands in such places as the inshore waters of Nigeria and The Philippines are not acts of piracy jure gentium.
