Application of a GIS-based stream buffer generation model to environmental policy evaluation 总被引:3,自引:0,他引:3
Wei-Ning Xiang 《Environmental management》1993,17(6):817-827
In this article a GIS method is presented for riparian environmental buffer generation. It integrates a scientifically tested
buffer width delineation model into a GIS framework. Using the generally available data sets, it determines buffer widths
in terms of local physical conditions and expected effectiveness. Technical burdens of data management, computation, and result
presentation are handled by the GIS. The case study in which the method was used to evaluate the stream buffer regulations
in a North Carolina county demonstrates its capability as a decision support tool to facilitate environmental policy formulation
and evaluation, and environmental dispute resolution. 相似文献

The objective of this research was to analyze the retention of acid precipitation as a viable policy issue on the Congressional
agenda during the 1980s. Issue maintenance (a term borrowed from Barbara Nelson's discussion of the four stages associated
with agenda decision making) was examined in relation to a set of issue characteristics originally developed by Roger Cobb
and Charles Elder, i.e., concreteness, social significance, temporal relevance, complexity, and categorical precedence. Each
issue attribute was found to be somewhat useful in explaining the longevity of acid rain as an agenda item although the direction
of influence for two factors, complexity and temporal relevance, was contrary to expectations. It was suggested that a conceptual
merger of this sort could contribute to the comparative analysis of agenda policy decisions by providing a clearer and more
restricted set of decision points to be explained. 相似文献

Environmental planning,ecosystem science,and ecosystem approaches for integrating environment and development 总被引:3,自引:0,他引:3
D. Scott Slocombe 《Environmental management》1993,17(3):289-303
Currently popular concepts such as sustainable development and sustainability seek the integration of environment and development
planning. However, there is little evidence that this integration is occurring in either mainstream development planning or
environmental planning. This is a function of the history, philosophies, and evolved roles of both. A brief review of the
experience and results of mainstream planning, environmental planning, and ecosystem science suggests there is much in past
scientific and professional practice that is relevant to the goal of integrated planning for environment and development,
but still such commonly recommended reforms as systems and multidisciplinary approaches, institutional integration, and participatory,
goal-oriented processes are rarely achieved. “Ecosystem approaches,” as developed and applied in ecology, human ecology, environmental
planning, anthropology, psychology, and other disciplines, may provide a more transdisciplinary route to successful integration
of environment and development. Experience with ecosystem approaches is reviewed, their advantages and disadvantages are discussed,
and they are compared to traditional urban and regional planning, environmental planning, and ecosystem science approaches.
Ultimately a synthesis of desirable characteristics for a framework to integrate environment and development planning is presented
as a guide for future work and a criterion for evaluating existing programs. 相似文献

/ This paper explores the new politics of western water policy through an examination of the Animas-La Plata water project and implementation of the Endangered Species Act. It is suggested that the focus of western water programming has shifted from the source of distributed funds, the United States Congress, to the agencies originally created to deliver federal benefits because funding for new project construction has not been forthcoming. Under this new system, members of Congress continue to excite their constituents with promises of money for new project starts, while the administrative agencies perform the myriad duties needed to keep these projects alive. The result is that political objectives have replaced operational/management objectives in administrative processes. In this case, the author demonstrates how resource managers in the Bureau of Reclamation manipulated hydrological analysis to control administrative process, why their manipulation was unfair, and perhaps illegal, and why biologists from the US Fish and Wildlife Service accepted the analysis. While ostensibly protecting all interests, the result is that none of the objectives of federal water programming are achieved.

/ The last 20 years have seen the successful application of environmental dispute resolution processes, where people voluntarily negotiate toward mutually acceptable solutions, to many environmental disputes. The effects of contextual influences, such as the number of parties and presence of deadlines, on outcomes are known and frequently described. Less well documented and understood are the interaction processes themselves. This paper draws on two case studies to develop a conceptual framework describing these processes. Disputes associated with management planning for the Bob Marshall Wilderness Complex in the United States and Fitzgerald River National Park in Australia provided the cases. The conceptual framework derived had eight sequential stages: (1) joint definition of problems, (2) uncertainty about what to do, (3) agreement on group procedures, (4) realization of interdependence, (5) enthusiasm about collective possibilities, (6) commitment to working together, (7) consolidation of the group, and (8) implementation of a resolution. The framework provides new insights for managers of public wildlands, especially the need for varying but ongoing managerial involvement in dispute resolution processes. High levels of involvement and influence are essential at the beginning in problem definition and group procedure design and at the end in implementing resolutions. Conversely, agency members must be willing to exert less influence, while still being involved and committed to collective purposes, during the middle stages. Also apparent from the conceptual framework is the importance of developing shared understandings and of allowing sufficient time for understanding to develop, if successful resolution is to be achieved.

本文通过对我国的环境管理发展历程分析后认为,我国的环境管理模式已由过去单一的管理模式转变为强化执法监督、加大投入、注重技术相互结合的综合型管理模式,在继续强化执法监督的同时,不断提高环保投入的比例和不断增加科技含量,是环境管理发展的趋势。 相似文献

ABSTRACTNeighborhood life expectancy varies by as much as 10 years across the City of Louisville. In 2013, the Greater Louisville Project funded by local government, businesses, and foundations, argued these differences had little to do with environmental factors. The Greater Louisville Project (2013) study argued that these neighborhood differences could be attributed 40% to socio-economic factors (with a major emphasis on education), 10% to physical environment, 30% to health behaviors, and 20% to access to medical care. To test these claims, we construct our own model of neighborhood variation in years of potential life lost (YPLL) by adding two variables testing environmental degradation. We operationalise two separate measures of environmental contamination: proximity to EPA designated brownfield sites and proximity to chemical factories in an industrial park in the neighborhood known as “Rubbertown”. We conduct several regression analyses, which show a relationship between proximity to environmental contaminants and an increase in neighborhood YPLL. Our beta weights challenge the claims made by the Greater Louisville Project, which minimize the impact nearness to environmental contaminants has on reductions in life expectancy in Louisville neighborhoods. 相似文献
