Impact scoping is the process of identifying important issues of a proposal and focusing the environmental impact assessment
(EIA) on the high-priority issues. Although impact scoping in one form or another has been inherent to EIA for some time,
documentation of its development and discussion of refinements to impact scoping processes have not been forthcoming. This
article traces the development of impact scoping through time and highlights the need for such processes in EIA. A focused
environmental assessment (FEA) approach to impact scoping that is suitable for implementation in an EIA is presented here
and advantages of its use are delineated. FEA is a three-staged process that encourages impact scoping through progressive
steps including impact identification, assessment and management planning. FEA combines a suite of EIA methods including:
issues matrices, impact hypotheses, valued ecosystem components, and stakeholder participation sessions to effectively integrate
impact scoping with EIA. 相似文献

A method for evaluating areas for national park status 总被引:1,自引:0,他引:1
Sümer Gülez 《Environmental management》1992,16(6):811-818
A procedure for evaluating different areas as national parks based on a scoring system is proposed. A National Park Evaluation
Form (NPEF) evaluating natural, cultural, and recreational resources in accordance with international criteria for national
parks is presented. The evaluation points given to an area indicate the possibility of the area becoming a national park.
In this method, subjectivity and bias have been minimized by a special application of the Delphi technique. The method outlined
here could help in the efforts of selecting and establishing national parks in many countries. 相似文献

A “finding of no significant impact” (FONSI) resulting from an environmental assessment (EA) was reported by the US Army in
June 1986 for the construction and utilization of a multipurpose range complex (MPRC) at the Pohakuloa Training Area, Hawaii.
There was little public response, and the US Fish and Wildlife Service and state agencies were consulted and had few comments
concerning the results of the botanical surveys used in the assessment. Construction of the $24 million project was begun
in 1988. Near the end of construction in 1989 a lawsuit was filed to halt construction because an environmental impact statement
(EIS) had not been done for the project, and the plaintiff thought that significant damage had occurred to several unusual
ecosystems. Judgment was against the plaintiff and construction continued. An appeal was filed with the 9th Circuit Court.
As MPRC construction was nearly complete, and on advice of Department of Justice lawyers, the Department of Army agreed to
settle out of court. The settlement in part called for: (1) the plaintiff to drop the appeal and allow construction to be
completed as scheduled, and (2) the Department of Army to prepare an EIS for the operation of the MPRC. A subsequent botanical
survey for the EIS discovered one endangered plant species, four category 1 candidate plant species (taxa with sufficient
data to support listing as endangered or threatened), three category 2 candidate plant species (taxa with some evidence of
vulnerability but insufficient data to support listing at this time), one category 3a species (presumably extinct taxa), and
possibly three undescribed species growing within the MPRC boundary. The MPRC case study is an excellent example of why the
National Environmental Policy Act (NEPA) must be modified to require in-depth and thorough environmental surveys. 相似文献

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

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
