Marine protected areas and local coastal conservation and management in Hong Kong

This paper focuses on the role of marine parks and reserves in the conservation of Hong Kong's coastal environment. This environment is under serious threat as a result of pollution of marine waters and habitat loss associated with urbanisation, large-scale reclamation projects, and inadequate treatment and disposal of sewage and industrial effluents. The paper discusses whether in a highly urbanised and stressed environment like Hong Kong, which currently lacks a conservation strategy and an overall framework for handling sustainability issues, small marine parks and reserves can be effective in helping to conserve local biodiversity. The paper also suggests that Hong Kong should adopt a broader regional perspective on its coastal conservation and management problems, a perspective that recognises the significance for the territory of the rapid urban and industrial development taking place in neighbouring Guangdong Province. This will require more extensive and focused liaison with Chinese agencies.     

A New Modus Operandi for the Agricultural Economics Profession

Agricultural economics has, until the 1990s, enjoyeda reputation for relevance and usefulness to theagri-food industry and policy-makers. Thatreputation has been jeopardized by a growinginfatuation with models and quantification, and aconcomitant underemphasis placed on many complexproblems and issues of society. An illustrativeexample is explored, using agriculturalactivity-related damage to the natural resourcebase, environment and ecology. Agriculturaleconomists are urged to respond by broadening theirterms of reference and joining forces with otherdisciplines.     

ISO 14000: A return to command and control?

Over the last few years, commentators on all sides of the environmental debate have (with a few exceptions) joined hands to pillory the traditional model of environmental regulation in this country. The catch phrase “command and control” has become emblematic of everything that was seen as being wrong with the old system. The current push for “reinvention” of environmental regulation reinforces the concept that although traditional methods have produced progress, they have outlived their usefulness. At the same time, ISO 14000 has emerged as one of the hottest topics in the environmental field—a form of reinvention of environmental management that has been embraced by many as the solution to an array of problems. While it is still early in the game, initial results indicate that when used effectively, ISO 14000 can be a powerful tool for the environmental manager. However, misuse of ISO 14000 could represent a throwback to command and control rather than a management tool for the new millennium. This article examines how this new tool fits into the evolving picture of environmental regulation and management.     

Focusing biodiversity research on the needs of decision makers

The project on Biodiversity Uncertainties and Research Needs (BURN) ensures the advancement of usable knowledge on biodiversity by obtaining input from decision makers on their priority information needs about biodiversity and then using this input to engage leading scientists in designing policy-relevant research. Decision makers articulated concerns related to four issues: significance of biodiversity; status and trends of biodiversity; management for biodiversity; and the linkage of social, cultural, economic, legal, and biological objectives. Leading natural and social scientists then identified the research required to address the decision makers' needs and determined the probability of success. The diverse group of experts reached consensus on several fundamental issues, helping to clarify the role of biodiversity in land and resource management. The BURN participants identified several features that should be incorporated into policy-relevant research plans and management strategies for biodiversity. Research and assessment efforts should be: multidisciplinary and integrative, participatory with stakeholder involvement, hierarchical (multiple scales), and problem- and region-specific. The activities should be focused regionally within a global perspective. Meta-analysis of existing data is needed on all fronts to assess the state of the science. More specifically, the scientists recommended six priority research areas that should be pursued to address the information needs articulated by decision makers: (1) characterization of biodiversity, (2) environmental valuation, (3) management for sustainability—for humans and the environment (adaptive management), (4) information management strategies, (5) governance and stewardship issues, and (6) communication and outreach. Broad recommendations were developed for each research area to provide direction for research planning and resource management strategies. The results will directly benefit those groups that require biodiversity research to address their needs—whether to develop policy, manage natural resources, or make other decisions affecting biodiversity.     

Emerging technologies for in-situ groundwater remediation

There are numerous technologies currently being tested by EPA, universities throughout the world, and private research organizations. A few of the more promising innovative technologies as well as fully tested and proven remedies for treating contaminated groundwater are presented in this article. Although several of those technologies have been in existence for only four to five years, the results of full-scale testing are being produced. The method for each of these promising technologies is described, results from recent field-scale studies are summarized, and a discussion of cost is presented.     

Electromagnetic fields in offices.

With the increased use of electric and electronic equipment in our offices, our daily exposure to electromagnetic fields has become increasingly complex due to the great variety of the frequency content of the fields. Today focus has shifted from monitors as the dominating sources of electromagnetic fields to other electronic equipment, cabling, nearby substations, power lines and stray currents in buildings. In the last 5 years wireless communication has become common in our offices. These devices use radio frequency waves to communicate and are therefore sources of radio frequency fields in our offices. To a certain degree, they all add to the complicated issue of the extensive field frequencies found in offices. The exposure of office workers is generally considered to be low and not in conflict with the existing guidelines, but if a precaution approach is applied there are a number of measures that can be taken to reduce the electromagnetic fields in offices in order to obtain a good electrical environment.
