A Critical Review of Environmental Impact Statements in Sri Lanka with Particular Reference to Ecological Impact Assessment

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.     

EIA application in China's expressway infrastructure: clarifying the decision-making hierarchy

China's EIA Law came into effect in 2003 and formally requires road transport infrastructure development actions to be subject to Environmental Impact Assessment (EIA). EIAs (including project EIA and plan EIA, or strategic environmental impact assessment, SEA) have been being widely applied in the expressway infrastructure planning field. Among those applications, SEA is applied to provincial level expressway network (PLEI) plans, and project EIA is applied to expressway infrastructure development 'projects' under PLEI plans. Three case studies (one expressway project EIA and two PLEI plan SEAs) were examined to understand currently how EIAs are applied to expressway infrastructure development planning. Through the studies, a number of problems that significantly influence the quality of EIA application in the field were identified. The reasons causing those problems are analyzed and possible solutions are suggested aimed at enhancing EIA practice, helping deliver better decision-making and ultimately improving the environmental performance of expressway infrastructure.     

EIA-Learning from Experience: Changes in the Quality of Environmental Impact Statements for UK Planning Projects

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.     

Road Developments in the UK: An Analysis of Ecological Assessment in Environmental Impact Statements Produced between 1993 and 1997

Environmental impact assessment (EIA) has been required for certain proposed road developmentsin the UK since EC Directive (85/337) was implemented in 1988. The extent to which the requirements of the EIA Directive are met with respect to ecological issues has been explored in earlier reviews of road statements (Treweek et al., 1993) and of UK environmental impact statements (EISs) in general (Thompson et al., 1997). This paper describes the results of a further review of 40 EISs produced between 1993 and 1997 and also examines recent changes in the political context for EIA of proposed road developments,including developments in UK transport policy and the UK biodiversity process. The results of the review suggest that the ecological assessment of proposed road developments has improved in some respects, but also highlights the persistence of many shortcomings identified in earlier reviews. The reasons for ongoing failure to address these issues are explored. Key findings include a marked improvement in the extent of reference to consultation with statutory consultees and an increase in the proportion of EISs reporting the results of new ecological surveys. However, while potential ecological impacts were discussed in all the EISs reviewed, many still failed to predict the full range of potential ecological impacts.     

Environmental Impact Assessment and Environmental Audit in Large-Scale Public Infrastructure Construction: The Case of the Qinghai–Tibet Railway

Large-scale public infrastructure projects have featured in China’s modernization course since the early 1980s. During the early stages of China’s rapid economic development, public attention focused on the economic and social impact of high-profile construction projects. In recent years, however, we have seen a shift in public concern toward the environmental and ecological effects of such projects, and today governments are required to provide valid environmental impact assessments prior to allowing large-scale construction. The official requirement for the monitoring of environmental conditions has led to an increased number of debates in recent years regarding the effectiveness of Environmental Impact Assessments (EIAs) and Governmental Environmental Audits (GEAs) as environmental safeguards in instances of large-scale construction. Although EIA and GEA are conducted by different institutions and have different goals and enforcement potential, these two practices can be closely related in terms of methodology. This article cites the construction of the Qinghai–Tibet Railway as an instance in which EIA and GEA offer complementary approaches to environmental impact management. This study concludes that the GEA approach can serve as an effective follow-up to the EIA and establishes that the EIA lays a base for conducting future GEAs. The relationship that emerges through a study of the Railway’s construction calls for more deliberate institutional arrangements and cooperation if the two practices are to be used in concert to optimal effect.     

EIA in a risk society

Environmental Impact Assessment (EIA) was developed and introduced in the 1960s during a time that was dominated by three key societal influences. These were the growth of modern environmental concern, the drive for more rational, scientific and objective environmental decision making and a desire for more public involvement in environmental decision making. The legitimacy of EIA, as a tool to aid decision making, lies in its ability to meet the requirements of all three demands, the chief among these being its ability to be a systematic scientific and rational approach to decision making. Yet today we live in a society that no longer accepts the rationalist model as either possible or desirable. The deference to ‘the expert’ and our trust in science and technology has steadily declined during the period of EIAs development and widespread use. Today, EIA still depends for its legitimacy on its claim to provide a systematic and scientific approach to assessments, while society has moved on. This paper examines this growing divergence and argues that it is time for a major re‐evaluation of the role of EIA in environmental decision making.

Discretionary Judgement in Local Planning Authority Decision Making: Screening Development Proposals for Environmental Impact Assessment

Screening is a critical decision-stage in the Environmental Impact Assessment (EIA) process and involves the determination of whether or not a development proposal will require EIA. This decision requires a discretionary judgement on whether the development has the potential to cause ‘significant environmental effects’, and consequently there is potential for diversity to exist in formal requests for EIA. Drawing upon a comprehensive survey of Local Planning Authorities (LPAs) in England and Wales, this paper explores the characteristics of LPA screening decision making since the introduction of revised EIA regulations in March 1999. The paper starts with a theoretical overview of rationality, decision making and planning theory, followed by a brief review of the regulatory context of EIA screening. The research approach is then outlined and the survey findings are presented, including a detailed consideration of organizational and individual level analyses set within the context of planning theory judgement debates. Comparisons with other European countries are briefly made, before drawing conclusions and recommendations.     

Policy And Practice Environmental Assessmentand Planning: A Chronology of Development in England and Wales

The development of regulations to implement Environmental Impact Assessment (EIA) in England and Wales occurred initially as a response to European Community Directive obligations. Since then, a proliferation of regulations has resulted from the need to meet those obligations which were not covered successfully by the first tranche of legislation; the desire to extend the range of project types requiring EIA beyond those specified in the Directive; and the need to respond to changes brought about by privatization.As a result, current regulations relating to EIA are extremely complex and are in a constant state of flux. This inevitably causes problems for those responsible for their implementation. Ten years after the 1985 Environmental Impact Assessment Directive was notified to the Member States, it has undergone a review and the European Commissionhas reached a common position on the proposedamendments.The implementation date for Member States to meet the requirements of the amended Directive is 31 December 1997 (ENDS, 1996). However, the 1985 Directive has yet to be fully implemented in the UK.

Mainstreaming environmental impact assessment as a tool for environmental management in Ethiopia: Current challenges and directions for future improvements

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.     

The typography of environmental impact statements: Criteria,evaluation, and public participation

Guidelines for implementation of the National Environmental Policy Act state that environmental impact statements (EISs) shall use “appropriate graphics.” We examined one component of graphics, typography, identifying applicable criteria from the literature and applying them to 150 EISs prepared by seven agencies. We found that the EISs ranged widely in typographic quality. The average EIS met fewer than seven of ten criteria; 12% were considered unreadable. The results suggest that weak typography may seriously limit public review of EISs. Agencies are encouraged to make typography a serious component of their public participation programs.     

Public involvement in the EIS process

In the United States public involvement in the Environmental Impact Statement (EIS) process is required by Council on Environmental Quality (CEQ) Guidelines, Executive mandates, and agency guidelines. Public participation after the initial Environmental Impact Assessment (EIA) and throughout the preparation of the Draft Environmental Impact Statement (DEIS) is desirable for it permits contributions from:

1. those who are directly affected by a proposed project.
2. individuals with expertise in environmental fields that may be affected by government action.

Early public participation can be useful in identifying environmental problems and potential sources of controversy. A systematic approach should be applied by government agencies to solicit public opinion throughout the preparation of the DEIS. Early, active, and meaningful participation particularly by those government and public segments most affected by the proposed project is a positive step towards effectively using the EIS as a management tool for mitigating impacts to the human environment. Here we discuss the role of public participation in the EIS process and develop an approach for initiating early and expressive public participation.     

Threatened Species Conservation in New South Wales,Australia: A Review of the Value of the Eight-part Test

The Threatened Species Conservation (TSC) Act, introduced in 1995, represents a significant attempt to conserve and restore biodiversity within the state of New South Wales, Australia. This Act aims to integrate land use planning and environmental impact assessment legislation by placing increased responsibility on applicants, proponents, consent and determining authorities, and the New South Wales National Parks and Wildlife Service, in the fields of environmental planning, development control and biodiversity conservation. The TSC Act introduced a set of eight factors which have to be considered by decision makers in determining whether a development is likely to have a significant effect upon threatened species, populations, ecological communities or their habitats (the threatened biota) as listed in the Act. These eight factors are commonly referred to as the 'eight-part test'. Fifty environmental impact statements (EISs) containing eight-part tests for development proposals were obtained. The adequacy of scoping and survey exercises, the number of species identified and afforded the eight-part test, and the actual responses to each of the eight factors contained within the test, using a series of criteria, were ascertained. Sixty per cent provided an adequate scoping exercise; 6% of the surveys for flora species, and none for fauna species carried out, were adequate in terms of identifying all threatened species on the development site. Seven hundred and thirty-seven species listed in the Act were identified, 36% of which were omitted from the eight-part test procedure. The eight sections of the eight-part test were completed to a varying degree of adequacy, with none of the EISs completing all eight sections satisfactorily. Both section 4 (regarding the impacts of a development in terms of habitat isolation) and section 8 (regarding the distribution of species potentially affected by a development) were inadequately completed in all 50 EISs.     

Visual impact assessment: A neglected component of environmental impact statements in Ireland?

This paper documents the results of an analysis of Visual Impact Assessments (VIA) within a sample of Environmental Impact Statements (EIS) in Ireland. The standard of VIA conducted within the environmental impact assessment (EIA) process for three categories of development; piggeries, quarries and urban developments between 1997 and 1999 are evaluated. The extent to which VIA have complied with the Irish Environmental Protection Agency (EPA) guidelines and disparities between the results for each development category are examined. The survey concluded that (i) the standard of VIA is less comprehensive than might be expected, and (ii) the use of visualization techniques for VIA could be substantially improved.     

A landscape vulnerability analysis method proposal and its integration in the EIA

Landscape is the area primarily affected by proposed human projects. The prediction and evaluation of the potential anthropogenic impacts under Environmental Impact Assessment (EIA) is therefore one of the major environmental tools for prevention of any deteriorative or destructive actions. To conduct EIA properly requires inclusion of a determination of landscape vulnerability which expresses the possible landscape reaction to impacts of any exogenous factors. When it is designated correctly, the suitable human activities are determined more accurately. Even though many techniques for this have been suggested worldwide, lots of deficiencies have surfaced in their application. This paper presents a method for landscape vulnerability analysis which consists of qualitative evaluation of landscape receptors, their scoring, the vulnerability degree calculation, and overall reliability evaluation. The method proposed can improve the impact objectivity of prediction and evaluation and the suggestion of precise mitigation measures with the purpose of achieving sustainable landscape management.
