The First Step for the Environmental Management of Australian Beaches: Establishing an Effective Policy Framework

Beach management and coastal management are interwoven and scale-dependent activities in Australia. Present coastal policies are broad and designed for large, national, and statewide scales. They specify ecologically sustainable development as the overarching goal for coastal management and provide the context for beach management. On smaller scales, an approach focusing on the reduction of geomorphic hazards as the basis of beach management was established by the Coastline Hazard Policy, with nonhazard aspects of beach management such as ecological, economic, and social concerns assuming secondary importance. Although beach management can occur effectively under these coastal management arrangements, better guidance is required to make this process as effective and efficient as possible. This guidance - the policy framework - could be better developed for beach management and better integrated with existing coastal management arrangements. While this policy development is not strictly necessary to achieve positive outcomes from beach management, it is necessary to effectively guide implementation of the existing broad coastal policies. Effective goals for beach management are yet to be thought out and clearly articulated in Australia. A good start would be to couple the present goals of ecologically sustainable development and hazards reduction into a coherent goal for beach management. A specific policy for beaches should be developed given the importance of beaches in Australia.     

Cultural Models of Pfiesteria : Toward Cultivating More Appropriate Risk Perceptions

Based on semistructured interviews (N = 7), informal interviewing (N = 63), and a survey (N = 790), this article describes the cultural models used by mid-Atlantic residents to understand Pfiesteria piscicida. A cultural model is a simplified way of understanding a complex system, shared by members of a culture. Eighty-eight percent of respondents understood Pfiesteria using one of four previously existing cultural models: a disease in fish, a parasite in fish, a water pollutant, and a toxin or poison. These models are not used by marine biologists, who are more likely to refer to Pfiesteria taxonomically or, in its fish killing form, to call it a predator. Our survey shows that the cultural model a respondent holds is correlated significantly with his or her believed pathway of human harm (e.g., eating fish versus swimming) and is correlated significantly but weakly with his or her behavioral responses. We conclude that existing cultural models, as the public has applied them to Pfiesteria, have led people to avoid a range of coastal activities and seafoods, in virtually all cases unnecessarily. Cultural models appear to explain public reaction better than previously hypothesized factors such as inaccurate media coverage. These findings suggest an approach to developing a pedagogical and communications strategy which could provide the public with a cultural model better matched to Pfiesteria.     

Learning Frontiers in the Practice of Integrated Coastal Management

Since the Rio conference in 1992 investments in integrated coastal management (ICM) have increased dramatically. National and subnational governments have undertaken many initiatives to protect and develop coastal areas. Extensive field experience has advanced understanding of the operational attributes of ICM. This article reviews the principles and operational attributes of ICM that have become well accepted, particularly from the perspective of international ICM donors and professionals. A common understanding of the fundamentals of ICM provides a base from which targeted and systematic study and assessment of ICM can be conducted. Several thematic areas are suggested where there are currently important needs and opportunities for collective study and learning in ICM. The important role of donors is emphasized in supporting collaborative learning initiatives that advance understanding of ICM, and improve and expand the practice.     

Valuing Estuarine Resource Services Using Economic and Ecological Models: The Peconic Estuary System Study

This article summarizes four integrated economic studies undertaken to contribute to resource preservation and restoration decisions for the Peconic Estuary System of Suffolk County, NY. Completed as part of the National Estuary Program, the studies apply distinct resource valuation methods to a wide range of resource issues. The principal goals of this article are to highlight different methodologies that may be used to assess nonmarket economic values in a coastal management context, and characterize differences in the results that one may expect from each approach. We also emphasize potential relationships among values estimated by different nonmarket methodologies, and comment on the implications of these relationships for the interpretation and use of economic value estimates.     

Lancaster sound regional study: Coastal and marine resource planning in the Canadian high arctic

Abstract

The Lancaster Sound Regional Study serves as a pilot project for regional planning in the Arctic. Probably the most biologically productive area of all arctic regions, Lancaster Sound represents a unique Canadian heritage. And since it occupies the strategic eastern entrance to the Northwest Passage, the Sound has long been a summer shipping route. Now, proposals are under review that would permit year‐round shipping of oil and gas from the Beaufort Sea by means of ice‐breaking tankers. Also proposed are the exploration and development of possible hydrocarbon reservoirs within the Sound. Actual decisions for the area's use must respect the interests of the native Inuit who have lived there for centuries as well as the preservation of the environment. This paper describes the preliminary phase of the regional planning for the region: the preparation of a public discussion paper to elicit informed comment and opinion on future uses of the Sound. It is a first step toward recommending suitable management and use options for the region.     

Developing management guidelines for oil and gas activities: The louisiana experience

Abstract

Preliminary management guidelines have been derived for oil and gas activities in coastal Louisiana. Derivation of these guidelines was done in terms of the natural function of the coastal ecosystem; this means that all economic activities should be designed to complement natural function as much as possible. The guidelines range in scope from very specific, almost performance standards, to very general admonitions. For example, we have suggested that spoil banks, produced as a result of dredging, should not be higher than the height of the daily tide or roughly 15 cm in coastal Louisiana, and at the other extreme, we have suggested that all dredging should be done with great care during wildlife migrations, spawning, and nesting times.     

The funding of hierarchical railway development in China

Transport networks are hierarchal in essence. In this paper, we explore the relationship between the financing structure and the hierarchal evolution of railway network development, using the case of China. Although privatization and corporatization in transport provision have been trends in some parts of the world, the national government is still the main body responsible for railway development in many countries. Among these countries, China and India are the only two that include the Ministry of Railways (MOR). In India, the entire country's railways are clearly defined as public services provided and managed by the MOR. In China, railways have been corporatized; yet, the MOR and the National Railway Corporation are still widely regarded as a single body that has monopolistic power over almost all railway systems at the national and regional levels in both infrastructure development and operation.
