Experiences with environmental impact assessment (EIA) in a number of countries are discussed in the light of both explicit and implicit goals and objectives. Adequate environmental information is not always available to decision makers because of failure to apply EIA to all relevant decisions, the continuing inadequacies of prediction and evaluation techniques, the failure to consider alternatives adequately, and the bias of some EISs. EIA frequently results in changes to proposals and may result in stricter environmental management conditions in some cases, but some people regard it as a failure because it has not stopped development. Generally, EIA leads to better integration of environmental factors into project planning. Open procedures and freedom of information encourage responsiveness to EIA procedures, which can be weakened by discretionary powers and lack of access to the courts by public interest groups. However, legal standing may have side effects that offset its advantages. EIA can encourage cooperation and coordination between agencies but does not ensure them. Similarly, it can have a limited role in coordinating interstate and international policies. In the long term, the success of EIA depends on adequate monitoring, reassessment, and enforcement over the life of the project. EIA has generally opened up new opportunities for public participation, and may help to reduce conflict. EIA procedures need to be integrated with other environmental protection and development control programs, and various means exist for reducing its cost to developers and the public.  相似文献

This article reviews the application of environmental impact assessment (EIA) procedures and practices to three watershed modification projects situaled in western Canada. These ventures were justified for accelerating regional economic development, and cover the period during which public concerns for protecting the environment rapidly made their way into the national political agenda. An historical account and analysis of the situation, therefore, seems desirable in order to understand the development of EIA processes, practices, and methodologies since the start of construction of the first project in 1961. This study concludes that there has been good progress in predicting and evaluating environmental and related social impacts of watershed modification proposals. However, a number of obstacles need to be overcome before EIA can firmly establish itself as an effective planning tool. These difficulties include jurisdictional confusions and conflicts, division of authority and responsibility in designing and implementing appropriate mitigative and monitoring measures, lack of tested EIA methodologies, and limited availability of qualified human resources. A number of conclusions and suggestions are offered so that future watershed modification proposals may be planned and implemented in a more environmentally sustainable fashion. These include: (1) EIA processes must be completed before irrevocable decisions are made. (2) Any major intrusion into a watershed is likely to impact on some major components of the ecosystem(s). (3) Mitigation costs must form part of the benefit-cost analysis of any project proposal. (4) Interjurisdictional cooperation is imperative where watersheds cross political boundaries. (5) The EIA process is a public process, hence public concerns must be dealt with fairly. (6) The role of science in the EIA process must be at arms length from project proponents and regulators, and allowed to function in the interest of the protection of the environment and public health and safety. The views expressed here are the authors’ own and do not necessarily reflect those of FEARO and/or other government agencies and officials involved in the review of these projects.  相似文献

/ Environmental impact assessment (EIA) has been identified as an important instrument for facilitating sustainability. However, to do so requires the integration of sustainability into EIA theory and practice. The sustainability concept is a valid and important environmental management perspective. However, many issues and obstacles need to be addressed further if the concept is to be translated into practical strategies. Sustainability can potentially infuse EIA with a clearer sense of direction, an ethical foundation, a mechanism for establishing priorities and assessing choices, and a means of linking EIA to other environmental management instruments. Conceptually, EIA and sustainability can be integrated, but frameworks should be refined, adpated to context, and linked to related initiatives. Sustainability should be explicitly incorporated into EIA legislation, guidelines, and institutional arrangements. An experimental approach to testing, assessing, and sharing experiences is suggested.A framework is first presented that defines and characterizes the sustainability concept. A further framework is then described for integrating sustainability into EIA at the conceptual level. The integration of sustainability and EIA at the regulatory level is next addressed through an overview of sustainability initiatives in EIA requirements in Canada. The Canadian examples include many promising initiatives but these and other experiences will need to be monitored, shared, and integrated into comprehensive environmental management strategies. Finally, means of incorporating sustainability into each activity in the EIA planning process are identified.KEY WORDS: Sustainability; Environmental impact assessment  相似文献

Environmental impact assessment (EIA) procedures have been in existence in the People's Republic of China over the last decade. The impetus for China's introduction of EIA was provided by the Environmental Protection Law of the People's Republic of China, which was adopted by the Fifth National People's Congress in 1979. The EIA process, which is administrative and not statutorily mandated, has been applied primarily to construction projects. Four stages are typically involved in an EIA investigation: design of the investigation, evaluation of background environmental quality, prediction of environmental impacts, and an assessment and analysis of the environmental impacts. A variety of approaches is used for predicting and analyzing environmental impacts, ranging from ad hoc methods to fairly sophisticated mathematical models. The results of the EIA investigation are compiled in an environmental impact statement, which is used as the basis for decision making by personnel in environmental protection departments. The EIA process does not include provisions for citizen notification or involvement. Views differ concerning the effectiveness of the EIA program in protecting China's natural, social, and cultural environments. Some hold that the EIA program has brought about improvement in environmental protection, while critics contend that the program has had little effect in the prevention of pollution. However, most, if not all, observers seem to feel that the program should be continued and improved. A major avenue for improvement is to place the evaluation of a particular project in a regional context. An earlier version of this paper was distributed at a workshop on Environmental Assessment Development Planning held in conjunction with the VII Annual Meeting of the International Association for Impact Assessment, Brisbane, Australia, July 5–8, 1988.  相似文献

How does knowledge management (KM) by a government agency responsible for environmental impact assessment (EIA) potentially contribute to better environmental assessment and management practice? Staff members at government agencies in charge of the EIA process are knowledge workers who perform judgement-oriented tasks highly reliant on individual expertise, but also grounded on the agency’s knowledge accumulated over the years. Part of an agency’s knowledge can be codified and stored in an organizational memory, but is subject to decay or loss if not properly managed. The EIA agency operating in Western Australia was used as a case study. Its KM initiatives were reviewed, knowledge repositories were identified and staff surveyed to gauge the utilisation and effectiveness of such repositories in enabling them to perform EIA tasks.  相似文献

Environmental impact assessment (EIA) has been promoted as an instrument for preventive environmental management in construction projects, but its performance in safeguarding the environment through influencing project decision-making is questioned. This paper probes the underlying reasons from a governance perspective as an important supplement to the regulatory and technical perspectives. A framework, with process integration, professional governance, and public engagement being its key components, is proposed to analyze the governance arrangements that enable or inhibit the effective functioning of EIA, based on which a comparative study of three infrastructure projects in China, the United States and Finland was conducted. The results reveal that, while the level of process integration and public engagement of EIA determines the degree to which EIA influences project decisions, it is the professional governance that controls the accountability of EIA. The paper has implications on institutionally where efforts should be directed to improve the performance of EIA.  相似文献

Virtually every environmental planner at some time deals with environmental impact assessment (EIA). Public participation is required in most environmental impact assessment programmesaround the world. However, citizen involvement is often reduced to a procedural exercise instead of a substantive process to include the public in environmental decision making. This paper examines public participation in EIA and provides ways to improve its effectiveness. We first examine the rationales for public involvement and its institutionalization through EIA. Next, we analyse the shortcomings and strengths of common approaches to public involvement. Our analysis, supported by two case studies, suggests that going beyond the minimum requirements can benefit the public, the project proponent and the final plan. We conclude with practical steps to improve public participation programmes in environmental planning and decision making.  相似文献

A large body of literature addresses the role of science in environmental impact assessment (EIA) but less attention has been given to the views of practitioners themselves. In this research a survey of 31 EIA practitioners in Western Australia was undertaken to determine their perceptions of the quality and importance of science in EIA. The survey results are compared with previous theoretical, empirical, and survey studies of the role of science in EIA. Interview questions addressed the role of science in impact prediction, monitoring activities, mitigation and management, and EIA decision-making. It was clear from the interviews that many practitioners are satisfied with the quality of science currently used in EIA, but do not believe that it is given sufficient importance in the process. The quality and importance of science in the predecision stages of EIA was rated higher than in the postdecision stages. While science was perceived to provide the basis for baseline data collection, impact prediction, and mitigation design, it was seen to be less important during decision-making and ongoing project management. Science was seen to be just one input to decision-makers along with other factors such as sociopolitical and economic considerations. While time and budget constraints were seen to limit the scientific integrity of EIA activities, pressure from the public and regulatory authorities increased it. Improving the scientific component of EIA will require consideration of all these factors, not just the technical issues.  相似文献

Conditions in Guatemala's Rio Dulce National Park (RDNP) present an immediate decision-making challenge concerning the reversal of current destructive environmental trends, and in establishing policies for restoration, protection, and sustainable use. This article summarises results of environmental assessment activities undertaken at three levels: an environmental impact assessment (EIA) of a proposed industrial forestry activity, an environmental assessment of management options for the Rio Dulce National Park, and water management planning for the Rio Dulce/Lago Izabal watershed. A key result of the EIA was to prohibit construction of a barge terminal within the boundaries of the park because it could set a precedent for future development. Management options for the park focused on establishing land-use controls, dealing with river transport more effectively, and identifying funding mechanisms to implement solutions. At the watershed scale, a strategic approach was recommended to identify priority issues for initiating change toward sustainability in the region.  相似文献

Since environmental impact assessment (EIA) is concerned primarily withsignificant environmental impacts, the concept of impact significance deserves to be defined and applied rigorously. In this article use of the term over the past 15 years in EIA documentation is reviewed. Some recent attempts at elucidating the concept are summarized. Four perspectives on impact significance that emerged from a series of workshops on the ecological basis for EIA are presented. These perspectives include (a) statistical (related to problems of isolating project-induced changes from natural variation), (b) ecological (related to the importance of project-induced changes from a purely ecological perspective), (c) social (related to the acceptability of project-induced changes in important environmental attributes), and (d) project (related to whether project-induced changes will indeed influence project decision making). The following synthesis is proposed: Any exercise in judging the significance of an environmental impact should thoroughly consider (a) the importance of the environmental attribute in question to project decision makers, (2) the distribution of change in time and space, (c) the magnitude of change, and (d) the reliability with which change has been predicted or measured. The implications of considering these factors are discussed.  相似文献

This paper explores the extent to which Western approaches to public involvement in environmental impact assessment (EIA) have been transferred to Vietnam, constraints on their use, and their appropriateness for the Vietnamese context. The research is based on an analysis of the public involvement content found in 26 EIA reports from development banks and interviews with 26 key informants. The study found that public involvement in Vietnam is generally technocratic, expert-driven and non-transparent, similar to the early days of EIA in the West and emerging economies. Public involvement usually occurs through authorised state channels such as commune leaders, mass organisations and professional organisations. The lack of a participatory culture for EIA, the nascent nature of grassroots democracy in the country, and Vietnamese cultural norms regarding respect for authority provide a challenging context for involving the public in EIA. The paper concludes by offering a number of suggestions for culturally appropriate public involvement at a time when Vietnam has just introduced mandatory public consultation for EIAs.  相似文献

Large-scale exploitation of fossil fuels and nuclear power can have an adverse effect on the human and natural environment. That need not be the case, if the effect on the environment is carefully assessed to ensure the development of a sustainable approach. This paper examines the process of environmental impact assessment (EIA) for coal from an international perspective. The concept of EIA is not new. A formalized process of EIA was introduced in the USA in 1970, and more recently similar legislation has been implemented in other countries. The member states of the European Community are required to adopt EIA regulations, as set out in Directive 85/337/EEC. Elsewhere, in Japan and Australia, there are requirements for EIA and a growing need for the process can be seen in developing countries. A comparison is made of the EIA process for coal in the international arena, and exemplary procedures are highlighted. Potential problems such as delays, modifications and additional costs are analysed, and the benefits of EIA, both to industry and environment, are discussed. A database of coal-related EIA would facilitate an exchange of information on the subject.  相似文献

/ The Galilee region on the northern edge of Israel constitutes more than 15% of the state's territory, supplies more than half of its drinking water needs, and is an important recreational resource and destination for Israelis. One of the main objectives of the plan for the Galilee was to devise a regional physical and economic development strategy for the years 1992-2007 that would arrest the trend of emigration of its residents, attract newly arrived immigrants to the region, and at the same time protect natural resources and environmental quality. This paper is limited to discussion of the environmental aspects of the plan. It analyzes spatial concepts for distribution of projected population growth, evaluates environmental impacts of alternative plans, and proposes a decision-making framework and tools for minimizing natural resources loss from development at the local level. Assessment of potential environmental impacts generated quantitative data of natural resources areas. Application of the data in the plan evaluation stage showed that the alternative that concentrated most of the new development in central Galilee was the second-best choice environmentally, but was preferred as the best choice for overall qualities. The planning study offers an alternative environmental impact assessment (EIA) process to the one presently used in Israel by incorporating environmental considerations at the initial plan-making stage and not at the plan-approval stage. It demonstrated that in order to be effective, environmental assessment and land-use planning should be seen as one effort that is integrated from the start and in each stage of the plan-making process.KEY WORDS: Environmental assessment; Development planning; Galilee  相似文献

In this paper the existing body of theory is reviewed to highlight the need for further attention to be paid to the EIA/management relationship. In particular it is shown that the majority of the literature to date has concentrated on the influence of EIA leading up to and including the decision to proceed or not with the proposed action. Less attention has been paid to the extension of the influence of EIA beyond this point to inform the process of ongoing environmental management. This relationship is then explored by reference to the Western Australian EIA system. One of the strengths of this system is its focus upon the implementation and management of proposed developments. The outcome of EIA is generally an approval to proceed with the development subject to meeting a suite of environmental design and management objectives.  相似文献

Use of the guild concept in environmental impact assessment   总被引:1,自引:0,他引:1  
The purpose of this paper was to clarify and expand several ideas concerning use of the guild concept in environmental impact assessment Background material on the concept and examples of its use are given. It is argued that for purposes of environmental assessment a resource-based guild approach is preferable to a taxonomic-based approach. Validity of the guild concept, problems in classifying species into guilds, implications of guild membership, and usefulness of guild analyses are discussed. I conclude that only with a thorough knowledge of both its limitations and benefits will it be possible to fully use the guild concept for understanding organizational processes in communities and ecosystems and for assessing environmental impacts.  相似文献

The Environmental Impact Assessment (EIA) was first entered into force in the United States of America in 1969 through the National Environmental Policy Act. Since then, the EIA was implemented in many other countries. In Ethiopia, EIA was formally introduced in 2002 by Proclamation No. 299/2002 after the establishment of the Environmental Protection Authority (EPA) in 1995 and the formulation of the Environmental Policy of Ethiopia (EPE) in 1997. This study, which is based on a document review, interviews, and the application of a survey questionnaire, analyzes the procedures and practices of the Ethiopian EIA system, seeks to clarify fundamental information regarding the EIA system and characteristics of the key elements of EIA processes, and finally, offers suggestions that could improve EIA practices in the country. The overall result of this study shows that Ethiopia adopted EIA procedures that are similar to western models; however, despite approximately 15 years of experience, its implementation is still poor to the point that the use of EIA as an instrument of environmental management could be questioned. The challenges identified by this study include institutional, organizational, and professional capacity gaps, which, in turn, have resulted in constraints ranging from improper screening, scoping, and production of EIA reports to ineffective review, monitoring, and post‐project evaluation. Additional challenges to the system include poor governance and corruption, rapid economic growth, and the mushrooming of micro‐ and small‐scale enterprises that cause pollution and environmental degradation. This article also provides comprehensive suggestions to improve EIA practices in Ethiopia.  相似文献

The benefits of strategic environmental considerations in the process of siting a repository for low- and intermediate-level radioactive waste (LILW) are presented. The benefits have been explored by analyzing differences between the two site selection processes. One is a so-called official site selection process, which is implemented by the Agency for radwaste management (ARAO); the other is an optimization process suggested by experts working in the area of environmental impact assessment (EIA) and land-use (spatial) planning. The criteria on which the comparison of the results of the two site selection processes has been based are spatial organization, environmental impact, safety in terms of potential exposure of the population to radioactivity released from the repository, and feasibility of the repository from the technical, financial/economic and social point of view (the latter relates to consent by the local community for siting the repository). The site selection processes have been compared with the support of the decision expert system named DEX. The results of the comparison indicate that the sites selected by ARAO meet fewer suitability criteria than those identified by applying strategic environmental considerations in the framework of the optimization process. This result stands when taking into account spatial, environmental, safety and technical feasibility points of view. Acceptability of a site by a local community could not have been tested, since the formal site selection process has not yet been concluded; this remains as an uncertain and open point of the comparison.  相似文献
