Environmental assessment (EA) of the impacts of development is required under the 1985 European Directive 85/337/EEC, which is implemented in Britain primarily through the 1988 Town and Country Planning (Assessmentof Environmental Effects) Regulations. Ecology provides analytical procedures for studying relationships between organisms and their environment and therefore has an obvious role in EA. The status of ecology within the British EA process was investigated by analysing 179 environmental statements (ESs) produced between 1988 and 1993. In many cases, the ecological information provided was so limited in quantity, or of such poor quality, that it was not possible to assess the ecological implications of proposed schemes. Many ESs failed to provide the data necessary to predict ecological impacts. Potential ecological impacts were reported in 93% of statements, but only 9% made any attempt to quantify them. Of those ESs which made references to ecological effects, only 45% based their findings on new ecological survey information. Consultation with statutory consultees for nature conservation was reported in 48% of ESs. Although 78% of ESs mentioned mitigation measures, only 23% described them in detail. A major shortcoming was the universal failure to make any commitment to monitoring of development impacts. In addition to the lack of formal requirements for monitoring, the lack of guidance for ecologists and developers involved in EA is concluded to be a major factor behind some of the shortcomings summarized in this paper.  相似文献

This article critically reviews environmental assessment (EA) practices in Sri Lanka, with a particular focus on ecology. An overview is provided of the domestic and international influences which have shaped the administrative process which is currently a two-tiered scheme. An Initial Environmental Examination (IEE) provides a preliminary screening tool, prior to the requirement for a full Environmental Impact Assessment (EIA). A comprehensive survey of Sri Lankan national archives showed that 463 EAs were completed in the period 1981–2005, with the bulk of these in the more populated Western and North Western Provinces. Two-thirds were IEE surveys, while the remaining third advanced to full EIA. A representative sample of 130 EAs (both IEEs and full EIAs) spanning a broad range of project types, scales, and environmental settings was selected to evaluate the quality of the ecological investigations within the published environmental impact statements (EISs). These were assigned into five classes of “explanatory power”, on the basis of their scientific content in relation to survey, analysis, and reporting of ecological interests. Within most EISs, the ecological impact assessment (EcIA) was restricted to the lowest two categories of ecological assessment, i.e., tokenistic presentation of reconnaissance-level species lists without further analysis of the development implications for individual organisms or communities. None of the assessments reviewed provided statistically rigorous analysis, which would be required if ecological impact studies are to include quantitative and testable predictions of impact, which could then be followed up by appropriate post-impact monitoring programs. Attention to key local issues such as biodiversity or ecosystem services, which also have strong social dimensions in the developing world, was also notably underrepresented. It was thus concluded that despite the existence of a sound legislative framework in Sri Lanka, the analysis contained within EISs generally fails to convey meaningful information to the relevant stakeholders and decision makers involved in protecting ecological interests and promoting sustainable development. The introduction of strategic environmental assessment (SEA) is considered an important tool to strengthen the institutional capacity of Sri Lankan government to implement current regulations and, in particular, to combat the cumulative effects of incremental development.  相似文献

This paper draws on a research report recently produced (1996) by the authors for the UK Department of the Environment. The principal aim of the research was to establish clearly what changes, if any, there have been in the quality of Environmental Impact Statements (EISs) since the inception of mandatory EIA in 1988, and to explain reasons for the changes. The paper provides a critique of the meaning of 'quality' in an area such as this. Quality relates both to the EIS and to the EIA process. EIS quality can be assessed against various review frameworks in a structured and systematic way; quality can also be assessed according to the perspective of the individual participant in the EIA process. The findings of both macro and micro studies of quality are discussed. The macro study uses a range of review frameworks (minimum regulatory requirements, an EU framework, and comprehensive frameworks developed by EIA academics at UK universities, including Oxford Brookes University) for a large sample of EISs. The micro study uses a structured questionnaire of the participants (local planning officers, developers, consultants and others) involved in a smaller set of detailed case studies. The findings reveal that there has been a learning from experience and an improvementin quality, but they also highlight a number of problems in the EIA process. The paper outlines some of the determinants of the changes in quality, and concludes with recommendations for developments in EIA in response to particular issues raised. These recommendations are set in the context of European Commission amendments to the EC EIA Directive.  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

This paper discusses the treatment of social and economic impacts within UK environmental impact assessment (EIA). Socio-economic effects have an uncertain status in EIA, guidance on their assessment is limited and their treatment is often partial and of poor quality. This has led some commentators to view socio-economic impacts as the 'poor relations' in EIA. The paper presents the results of a recent review of the socio-economic component of UK environmental statements (ESs), which provides information on the extent, scope, balance and quality of socio-economic impact treatment. The review reveals that, although most ESs include some information on socio-economic issues, coverage tends to be narrowly focused on a small number of--primarily beneficial economic--impact types. Quantification of socio-economic impacts is also rarely attempted. The review findings are compared with those of similar studies undertaken in the mid-1990s, and the paper concludes with some recommendations for EIA practitioners relating to the treatment of socio-economic impacts.  相似文献

Characterized by expensive housing, high socioeconomic status, and topographic relief, Upper Sonoran Lifestyle communities are found primarily along the Wildland-Urban Interface (WUI) in the Phoenix, Arizona metro area. Communities like these sprawl into the wildlands in the United States Southwest, creating a distinct urban fringe. This article, through locational comparison, introduces and evaluates a new field assessment tool for monitoring anthropogenic impact on soil–vegetation interactions along the well-maintained multi-use recreational trails in Upper Sonoran Lifestyle region. Comparing data from randomly selected transects along other multi-use trails with data from a control site revealed three key indicators of anthropogenic disturbances on soil–vegetation interactions: soil disturbance, vegetation disturbance, and vegetation density. Soil and vegetation disturbance displayed an average distance decay exponent factor of −0.60, while vegetation density displayed a reverse decay average of 0.60. Other important indicators of disturbance included vegetation type, biological soil crusts, and soil bulk density. The predictive ability of this new field tool enhances its applicability, offering a powerful rapid ecological assessment method for monitoring long-term anthropogenic impact in the Upper Sonoran Lifestyle, and other sprawling cities along the WUI.  相似文献

This paper examines the role of environmental impact assessment (EIA) in project authorization decision making and the way in which the courts have interpreted its role. The purpose of the paper is to establish whether or not that role has changed over the period between the introduction of EIA in 1988 and 2001. From the evidence reported here, it is argued that while the procedural stages of EIA have been very much strengthened over that period, the importance of EIA as a tool to aid planning authorization decision making remains largely peripheral.  相似文献

With a view to suggesting ways in which we might arrive at a more socially acceptable waste management facility siting process, this paper considers the effectiveness of a more innovative approach to risk communication for a planned municipal waste-to-energy incinerator in Portsmouth, Hampshire, UK. The risk communication programme involved a contact group process designed to enable key members of the local community to participate in structured and informed discussions about the proposal before it was submitted as a planning application to the competent authority. The paper concludes that the communication model was dominated by the findings of technical assessments and that it provided only limited opportunities for interested stakeholders to participate fairly and competently in the development process.  相似文献

The achievement of sustainable development demands the integration of environment and development. To achieve sustainable development requires a close collaboration and cooperation between environmentalists and the decision-makers. The evidence is that in developing countries (Egypt, as an example) the gap is widening rather than closing. Intensive research programs are needed, for instance in the field of sustainable development and urban environmental management, to narrow that gap. Environmental Impact Assessment (EIA) has become a management tool for achieving acceptable forms of environmentally sound development and sustainability; at best it is proving nothing more than a permit to move a project ahead.It is recommended that indicators for sustainable development and their progress be fully monitored. Performance indicators should always be established, not only for project implementation, but also during and after the implementation process to make sure that all mitigation measures are satisfactorily implemented. This can be achieved by linking the license granting authority for action to the actual implementation of these measures. To secure the environmental sustainability of an environmental project, it is also important to have the EIA document as an integral part of the license application document, and to make it available to inspectors during their necessarily frequent inspection visits.  相似文献

Cross-city analysis in environmental regulation within non-democratic political systems is a neglected area. Taking policy convergence and styles of regulation as the focus, this paper has taken an initial step to compare the environmental impact assessment (EIA) regulation in Hong Kong and Shanghai. In this comparative exercise, it is identified that policy convergence occurs more explicitly in policy ideology and policy consequences, whereas divergence takes place in policy content, regulatory process and public consultation. Convergence, however, is only superficial whereas divergence is substantial. Indeed EIA systems of these two jurisdictions have displayed contrasting styles of regulation. The formal EIA system in Shanghai is dominated by the environmental agency, which regulates informal politics in the EIA process within a legal format. The informal EIA system in Hong Kong is co-ordinated by the environmental agency, which seeks active co-operation with the clients in a consultative EIA process in an informal and discretionary manner. What makes the Hong Kong system superior to the Shanghai system is the existence of institutional channels for public consultation. Within a non-democratic political setting, the EIA process in Hong Kong is more transparent and the EIA system is more accountable to the public, whereas the EIA process in Shanghai is lacking in transparency and the EIA system is under tight bureaucratic control.  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

Bioeconomy solutions potentially reduce the utilization demand of natural resources, and therefore, represent steps towards circular economy, but are not per se equivalent to sustainability. Thus, production may remain to be achieved against losses in natural resources or at other environmental costs, and materials produced by bioeconomy are not necessarily biodegradable. As a consequence, the assumption that emerging bioeconomy by itself provides an environmentally sustainable economy is not justified, as technologies do not necessarily become sustainable merely through their conversion to using renewable resources for their production. A source of the above assumption is that the utility of bioeconomy is mostly assessed in interaction between technology developers and economists, resulting in biased assessment with private commercial technology benefits being included, but environmental costs, especially longer term ones, not being sufficiently considered in the economic models. A possible solution to this conceptual contradiction may come from bioethics, as a strong concept in environmental ethics is that no technological intervention can be imposed on nature beyond its receptive capacity. To achieve a better balanced analysis of bioeconomy, environmental and ecological, as well as non-economic social aspects, need to be included in the overall assessment.  相似文献

Environmental impact assessment (EIA) is a procedure for predicting environmental impacts of projects prior to their development, while post-auditing seeks to assess the accuracy of such predictions. A literature review examines the need for post-auditing, highlighting several benefits to EIA performance that could arise if the results were effectively used. This reveals that, in practice, post-auditing activities are not widespread, and suggests reasons why this is so. An overview of post-audit findings from a survey of published studies is then presented, and it is concluded that there is much scope for raising the profile of post-auditing in EIA world-wide. Preliminary results from a recent UK post-auditing study based on eight projects are described. Information on impact predictions was gathered and compared with actual impacts. A total of 366 impact predictions were made of which 78% were qualitative in nature; 57% of the predictions were auditable and of these nearly three-quarters were accurate. Reasons for inauditability were ascertained including, for all cases, a lack of data or unsuitable information.  相似文献

Multicriteria decision analysis (MCDA) increasingly is being applied in environmental impact assessment (EIA). In this article, two MCDA techniques, stochastic analytic hierarchy process and compromise programming, are combined to ascertain the environmental impacts of and to rank two alternative sites for Mexico City’s new airport. Extensive sensitivity analyses were performed to determine the probability of changes in rank ordering given uncertainty in the hierarchy structure, decision criteria weights, and decision criteria performances. Results demonstrate that sensitivity analysis is fundamental for attaining consensus among members of interdisciplinary teams and for settling debates in controversial projects. It was concluded that sensitivity analysis is critical for achieving a transparent and technically defensible MCDA implementation in controversial EIA.  相似文献
