This study uses knowledge discovery concepts to analyze large amounts of data step by step for the purpose of assisting in the formulation of environmental policy. We performed data cleansing and extracting from existing nation-wide databases, and used regression and classification techniques to analyze the data. The current water hardness in Kaohsiung, Taiwan contributes to the prevention of cardiovascular disease (CVD) but exacerbates the development of renal stones (RS). However, to focus on water hardness alone to control RS would not be cost effective at all, because the existing database parameters do not adequately allow for a clear understanding of RS. Analysis of huge amounts of data can most often turn up the most reliable and convincing results and the use of existing databases can be cost-effective. 相似文献

The majority of environmental effects monitoring (EEM) frameworks that have been proposed compare selected indicator variables
as a means of assessing whether significant changes in stressed ecosystems have occurred. Most are deterministic in nature
and do not appropriately account for the natural variability and dynamics within the systems being comapred. This suggests
that the comparative procedures should be statistically based and immediately raises the issue of whether the selected comparative
procedures are to be used as decision-making tools or conclusive procedures. Conclusive procedures require a significant body
of evidence before rejecting the postulated null hypothesis. The costs and time involved in environmental data collection
accordingly bias action toward the maintenance of a status quo approach to environmental management. if, however, EEM is treated
as a decision-making procedure, risk functions that include consideration of type I and II statistical error may be developed
and combined with costs to select a minimum expected loss strategy for environemental management. Examples of the interpretative
difficulties and conclusion reversal phenomena caused when EEM is used as a conclusive procedure are presented. In addition,
risk functions appropriate for environmental management within an EEM context are constructed and applied. Only when such
tools are fully developed and applied can EEM expect to have significant impacts on minimizing environmental degradation. 相似文献

Review and challenges of policies of environmental protection and sustainable development in China 总被引:9,自引:0,他引:9
China is confronted with the dual task of developing its national economy and protecting its ecological environment. Since the 1980s, China's policies on environmental protection and sustainable development have experienced five changes: (1) progression from the adoption of environmental protection as a basic state policy to the adoption of sustainable development strategy; (2) changing focus from pollution control to ecological conservation equally; (3) shifting from end-of-pipe treatment to source control; (4) moving from point source treatment to regional environmental governance; and (5) a turn away from administrative management-based approaches and towards a legal means and economic instruments-based approach. Since 1992, China has set down sustainable development as a basic national strategy. However, environmental pollution and ecological degradation in China have continued to be serious problems and have inflicted great damage on the economy and quality of life. The beginning of the 21st century is a critical juncture for China's efforts towards sustaining rapid economic development, intensifying environmental protection efforts, and curbing ecological degradation. As the largest developing country, China's policies on environmental protection and sustainable development will be of primary importance not only for China, but also the world. Realizing a completely well-off society by the year 2020 is seen as a crucial task by the Chinese government and an important goal for China's economic development in the new century, however, attaining it would require a four-fold increase over China's year 2000 GDP. Therefore, speeding up economic development is a major mission during the next two decades and doing so will bring great challenges in controlling depletion of natural resources and environmental pollution. By taking a critical look at the development of Chinese environmental policy, we try to determine how best to coordinate the relationship between the environment and the economy in order to improve quality of life and the sustainability of China's resources and environment. Examples of important measures include: adjustment of economic structure, reform of energy policy, development of environmental industry, pollution prevention and ecological conservation, capacity building, and international cooperation and public participation. 相似文献

Two frequent beliefs about rural environmental attitudes are examined conceptually and empirically: (1) the common conception
that rural environmental concerns are expressed predominantly by wealthy community newcomers; and (2) the related position
that long-time rural residents are hostile to the environmental cause.
We argue conceptually, through the use of a 2×2 community matrix, that environmental attitudes are equally likely to be expressed
by what we term “upper middle income newcomers,” “lower middle income newcomers,” “upper middle income locals,” and “lower
middle income locals.” Empirically, we find that although wealthy newcomers express the strongest environmental attitudes
in the community, their concerns represent only a small percentage of rural environmental attitudes consisting of respondents
who make less than $40,000 a year in household income are over 40 years of age, possess less than a college education, and
work in a nonprofessional occupation. This new category expresses environmental concerns at least equal to the rest of the
community on three of four measures of environmental attitudes.
The findings provide insight into the widespread and cross-sectional nature of rural environmental concern. The implication
is that environmental groups will find significant sources of political support in rural communities, provided they craft
their environmental message in a language consistent with rural attitudes and values.
Things are gettin' bad fast. Easterners and environmentalists comin' down here from the big cities are tryin' to turn our
way of life completely upside down.

The quantities of water are not distributed uniformly in space and time. Greece compared to some other Mediterranean countries
is found in advantageous position regarding the availability of water resources. However, there are regions with great in
quantity water reserves and others with intense deficiencies. The management of water resources in Greece is concentrated
in the systematic spatiotemporal monitoring and forecast of two basic multidimensional parameters, the availability of water
resources and the water demand, as well as, in the implementation of necessary measures for the satisfaction of needs, regarding
the fields of economy and environment. This work describes and analyses the existing status of water resources in Greece,
as well as, the framework of applied policy. Furthermore, measures and actions for the management of water resources are proposed. 相似文献

In New Zealand environmental management is essentially the responsibility of land managers. Management decisions affect both production/productivity and the environment. However, responsibility for ensuring positive environmental outcomes falls on both local (Regional) and Central Government, and both they and international agencies such as the OECD would wish to monitor and report on changes. In terms of policy, strong links have been established via Central and Regional Government to land managers. Consumers in the market place are also, increasingly, requiring responsibility for positive environmental outcomes of those who purchase and process primary products. Strong links for responsibility have been established between our international markets and processing businesses and there is a noticeable strengthening of the links from the processors to the land manager/producer. In New Zealand a range of initiatives has been developed and implemented over recent times, whereby land managers are taking increasing responsibility for accounting for the environmental outcomes of their production activities. The range covers the spectrum from voluntary to compulsory (e.g., in order to meet market requirements) and from those initiated by customers to processor and/or producer initiatives. This paper follows the evolution of the principles that drove the predominant activities of the period and the processes that initiated the changes in environmental management. As the focus of agriculturalists changed from pioneering in a new world, to establishing a production base, to economic reality, and finally to environmental responsibility, the processes of extension adapted to meet the new challenge. 相似文献

This case study presents the series of decision-making processes surrounding a current environmental issue—the Portsmouth oil refinery in Virginia. Crude oil must be refined before it can be used as fuel. Additionally, some oil must be desulfurized for use other than as gasoline. In 1977, the nation imported about one million barrels of oil a day. Although the US Department of Energy has emphasized the critical need for greater east coast refinery capability, the east coast is to supply only 25% of its refined oil needs. In the same year, the east coast met its demands for petroleum products from three sources: (a) refinery production, 22.7%, (b) product imports, 28.0%, and (c) products from the Gulf Coast, 49.3%.1
The energy program after the Arab oil embargo has an objective of encouraging the construction of oil refineries and petrochemical plants in the United States rather than abroad. The tariff is higher on imports of refined oil products than of crude oil, and new refineries are allowed to import a large proportion of their requirements tarifffree.The US federal government does not directly regulate the locations for oil refineries or methods of desulfurization. The oil import program, however, does influence decisions concerning location of desulfurization facilities and refineries, and air and water pollution standards affect methods of refining, besides making desulfurization necessary.The opinions expressed in this article are those of the author and do not necessarily reflect those of the United States Department of Defense. 相似文献

The frequent charge that environmentalism is elitist is examined conceptually and empirically. First, the concept of elitism is analyzed by distinguishing between three types of accusations made against the environmental movement: (a)compositional elitism suggests that environmentalists are drawn from privileged socioeconomic strata, (b)ideological elitism suggests that environmental reforms are a subterfuge for distributing benefits to environmentalists and/or costs to others, and (c)impact elitism suggests that environmental reforms, whether intentionally or not, do in fact have regressive social impacts.The evidence bearing on each of the three types of elitism is examined in some detail, and the following conclusions are drawn: Compositional elitism is an exaggeration, for although environmentalists are typically above average in socioeconomic status (as are most sociopolitical activists), few belong to the upper class. Ideological elitism may hold in some instances, but environmentalists have shown increasing sensitivity to equity concerns and there is little evidence of consistent pursuit of self-interest. Impact elitism is the most important issue, and also the most difficult to assess. It appears that there has been a general tendency for environmental reforms to have regressive impacts. However, it is increasingly recognized that problems such as workplace pollution and toxic waste contamination disproportionately affect the lower socioeconomic strata, and thus reforms aimed at such problems will likely have more progressive impacts.This is Michigan Agricultural Experiment Station Journal article no. 11508. 相似文献

The prevailing system of environmental management strongly depends on the economic and political structures of a country and
is influenced by the current condition of them. Environmental degradation in the Soviet Union has been caused mainly by the
political and economic misconceptions listed in this article. With the transformation of its state order to the model of Western
democracies, the Soviet Union is experiencing a deep economic crisis of restructuring, reflected in a parallel crisis in its
system of environmental management, which is manifest in the form of rapid transformation. This is characterized by the contradiction
of the state’s old administrative institutions, which still exist, with the efforts to use market mechanisms of environmental
control. Such methods include various fees and payments for the use of natural resources or for pollution and creation of
specialized regional funds and banks to finance environmental programs. All these occur in the context of the strengthening
of regional sovereignty, the introduction of self-accounting for economic units, the adoption of comprehensive legal enactments,
and the setting up of an efficient administrative system of their enforcement. Public activism, as one of the principal actors
in this structure, also has undergone quick maturation. Nevertheless the future development of the new Soviet system of environmental
control remains uncertain because of the present unpredictability of the overall situation in the short run. 相似文献

Climate change is one of the major worldwide environmental concerns. It is especially the case in many developed countries, where the greenhouse gas emissions responsible for this change are mainly concentrated. For the first time, the Kyoto Protocol includes an international agreement for the reduction of the net emissions of these gases. To fulfil this agreement measures designed to reduce or limit current emissions have to be brought into force. Consequently, fears have arisen about possible consequences on competitiveness and future development of manufacturing activities and the need for support mechanisms for the affected sectors is obvious. In this paper, we carry out a study of the emissions of gases responsible for climate change in Asturias (Spain), a region with an important economic presence of sectors with intensive emissions of CO(2), the chief greenhouse gas. To be precise, in the first place, the volumes of direct emissions of the said gases in 1995 were calculated, showing that the sectors most affected by the Kyoto Protocol in Asturias are iron and steel and electricity production. Secondly, input-output analysis was applied to determine the direct and indirect emissions and the direct, indirect and induced emissions of the different production sectors, respectively. The results derived from the direct and indirect emissions analysis and their comparison with the results of the former allow us to reach some conclusions and environmental policy implications. 相似文献

Siting a geologic repository for isolating highlevel nuclear waste up to 10,000 years is a controversial undertaking never before attempted in the United States. The Nuclear Waste Policy Act of 1982 exempted repository siting from important requirements for environmental review under the National Environmental Policy Act. In December 1987, the Nuclear Waste Policy Amendments Act identified Yucca Mountain as the first site to be characterized for a high-level nuclear waste repository. In light of the unproven nature of the technology being evaluated, the scientific uncertainties associated with Yucca Mountain, and the lack of proven methods for risk evaluation, the environmental policies for repository siting represent a significant departure from more traditional, comprehensive, and interdisciplinary environmental review for siting nuclear projects. The policies warrant further study by those interested in how present as well as future decisions about complex technologies may be made. 相似文献

One major source of water-related health problems is the improper disposal of toxic substances in the environment. Toxic materials leaching from unregulated and unlined pits, ponds, lagoons, and landfills have created a widespread environmental nightmare in the United States and many other parts of the world. At present, there are two major and interrelated components of this problem in the United States. The first is the issue of cleaning up abandoned disposal sites that pose actual or potential threats to water supplies. The second aspect of the problem concerns the necessity of siting proper management, treatment, or disposal facilities in the future. Priorities must be set to allow efficient, effective, and equitable allocation of the scarce resources that are available for accomplishing these tasks.This article examines a number of the issues involved in setting these priorities, and presents the results obtained from a study of risk estimation and evaluation in the context of groundwater contamination by toxic substances. The article introduces a new concept of risk estimation, which is shown to produce more accurate and credible risk analyses. Finally, the relationships between risk credibility and public perceptions of procedural fairness and equity are examined as these factors bear on the institutional aspects of implementing policies for site cleanup and/or facility siting. 相似文献

Following the intent of the National Environmental Policy Act of 1969, many states have adopted policies and procedures directing state agencies and local government units to evaluate the potential environmental impacts of development projects prior to their undertaking. In contrast to a rich literature on federal requirements, current understanding of state environmental review is narrowly focused and outdated. This paper seeks to provide information on the landscape of state environmental review policy frameworks. The paper identifies 37 states with formal environmental review requirements through a document review of state statutes, administrative rules and agency-prepared materials, and confirms this finding through a survey of state administrators. A two-tier classification is used to distinguish states based on the approach taken to address environmental review needs and the scope and depth of relevant policies and procedures implemented. This paper also provides a discussion of policy and programme attributes that may contribute to effective practice, and of the potential for adopting relevant legislation in states where environmental review is currently lacking. 相似文献

The California Environmental Quality Act (CEQA) has evolved from a mini-NEPA, first enacted in 1970, into a procedural act
that affects the approval process of all large developments in California. In 1990, California local governments produced
over 1600 environmental impact reports and 30,000 initial studies under CEQA. Because of its widespread use, CEQA has periodically
drawn the attention of the state legislature, most recently in 1993, when over 60 CEQA reform bills were introduced. This
paper describes the CEQA process and evaluates its success at meeting its explicit and implicit goals. The research includes
a statewide survey of CEQA practice, sent to the planning departments of all 513 local governments in California in 1991.
Survey respondents agreed that CEQA helps in evaluating environmental impacts, reducing impacts, informing the public, and
coordinating public agency review. It is effective in reducing the environmental impacts of individual projects, but is not
as effective in improving environmental quality on an areawide scale. This research concludes that CEQA has led to positive
outcomes and is not as deeply flawed as many of its critics claim. Still, CEQA as currently designed may not be the optimal
vehicle for ensuring environmental quality. 相似文献

Since the term environmental ethics began to be used a generation ago, it has covered many different kinds of environmental notions, problems, ethical systems, and forms of behavior. A variety of cases are presented and examined under two terms,environmental ethics andecological morality, in an effort to illustrate different kinds of ethical objectives. In order to understand the connections between various strands of environmental ethics, personal and social values and subcultural norms of environmental ethics are examined under Christopher Stone's concept of moral pluralism. G. J. Warnock's notion of the general object of morality is proposed to integrate the variegated purposes of environmental ethics. 相似文献

We are witnessing a growing concern with the global dimension of many environmental issues, reflected in the increase in the number and significance of international environmental organizations. Yet there is no internationally applicable strategy for environmental research which is management oriented. A new type of research policy, which integrates ideas derived from environmental and human ecology, is required in order to deal with cultural and ecological diversity and their interactions as reflected in the ecology of landscapes. The newly defined concept of environmental health is proposed to fill this gap. This concept integrates the latest developments in landscape evolutionary ecology and environmental health, bringing out a conflict between making the environment conducive to human health and increasing the available options for supporting the essential biological and ecological processes of the environment. Lessons derived from the evolution of human environments are used in order to illustrate how health may become un umbrella for developing an environmental research policy, which could also serve as a catalyst for international environmental projects. 相似文献

The effects of social desirability on self-reported environmental attitudes and ecological behaviour
Taciano L. Milfont 《The Environmentalist》2009,29(3):263-269
There are several claims in the literature that social desirability concerns affect people’s response to self-reported measures
of environmental attitudes and ecological behaviour. However, only a few empirical studies have indirectly evaluated the impact of social desirability on environmental issues measures, and those who did have found only a low impact.
This article describes two studies that explicitly address whether socially desirable responding has direct and moderating effects on self-reported environmental attitudes
and ecological behaviour. Results from correlational and moderated multiple regression analyses from both studies showed that
social desirability had only a weak direct effect on environmental attitudes (but not ecological behaviour), and had no moderating
effect on the environmental attitudes–ecological behaviour relationship. Implications of these findings for research on environmental
issues are discussed.

environmental auditing must be rejected if the aim is to make companies introduce a specific management concept. Rather, it
is preferable to leave the search for effective environmental protection strategies to the competitive system, especially
since the criteria for environment-oriented management in the European Community audit proposal are without substance. Environmental
auditing can, however, assume a complementary function in the framework of an overall environmental policy if it is designed
as an information tool with which companies provide information on the development of environmental problems deriving from
their manufacturing processes and products. However, the model required to establish a framework of quantity and evaluation
criteria is not available. Further, auditing does not cover products. Similarly, there are no proposals defining the evaluation
procedure for ecological resource scarcity. Thus, the attempt of the Commission of the European Communities to create the
elementary prerequisites for consistent and verifiable environmental auditing in the corporate sector has failed. 相似文献
