The interminable issue of effectiveness: substantive purposes, outcomes and research challenges in the advancement of environmental impact assessment theory

An analysis of studies of the outcomes of environmental impact assessment (EIA) indicates that its role in consent and design decisions is limited, due primarily to passive integration with the decision processes it is intended to inform. How much EIA helps sustainable development is largely unknown, but it is hypothesised that it is more than is typically assumed, through a plethora of causes, including emancipation of stakeholders and incremental change in the bureaucracy, companies and scientific institutions. To enhance the effectiveness of EIA, research should focus more on theory about the nature and operation of diverse causal processes, even though the concepts, methods and analytical challenges would be substantial.

Integrating the environmental and economic consequences of converting to organic agriculture: evidence from a case study

In the current debate about the future of food quality, the merits of organic agriculture are frequently championed, but few studies have sought to integrate the changes in soil conditions, biodiversity and socio-economic welfare linked to the conversion from non-organic to organic production. This article aims to undertake this approach with respect to one case study. Its conclusions may not be representative for all organic conversions, but the findings are of relevance at a time of debate over changing patterns of subsidies and other incentives in agricultural policy. The study showed that there were demonstrable differences in overall environmental conditions in the comparison of organic and non-organic farming, with field evidence of increased species diversity, and an eventual improvement in the profitability of the organic farming regime. The broad conclusion is that there are definite environmental and economic advantages arising from organic agriculture that are not fully reflected in the present pattern of agricultural incentives. The study also showed that variations in farm management practice strongly influence the notion of on-farm and off-farm environmental consequences. The implications of these findings for the future of sustainable agriculture and for interdisciplinary science are also discussed.

Interpretations of sustainable agriculture in the UK

With the advent of Agenda 21, the blueprint for the transition to sustainable development for every nation on the globe, the issue of what exactly is sustainable agriculture is now being addressed, certainly throughout Europe. The food chain as a whole is the ultimate framework for a scrutiny of sustainability. However, this review looks only at the changing policy setting for seeking to define and implement sustainable agricultural practice in the UK. It analyses the key documents, reviews the state of science and assesses policy developments in wildlife/habitat management and the enhancement of scenery, from individual farms to whole landscapes. It concludes that there is neither the scientific understanding nor the economic tools to define and justify self-reliant agriculture on a farm-by-farm basis. Rather, it is more advantageous to devise integrated agricultural management arrangements for whole landscapes, crossing the borders of individual holdings. To do this, it is necessary to involve key stakeholders in the determination of the final landscape design. Then there is the tricky issue of how this may be implemented. That will be a sign that a policy for sustainable agriculture has come of age.

Impact mitigation in environmental impact assessment: paper promises or the basis of consent conditions?

This study analysed 40 planning applications in the East of England to investigate the practice of translating paper recommendations in the environmental statement (ES) into legal conditions and obligations. A high proportion (50%) of suggested mitigation measures were not translated into planning conditions or obligations. However, a significant number of additional conditions or obligations, not directly based on the ES, were imposed on developers. The research suggests a mismatch between the practice of those producing ESs and the expectations of planning authorities, leading to inefficiency and, possibly, emasculation of environmental impact assessment through a failure to implement mitigation. Several recommendations are made to increase the effectiveness of the implementation and integration of mitigation measures.

AN EVALUATION OF THE QUALITY OF ENVIRONMENTAL IMPACT STATEMENTS IN THESSALONIKI, GREECE

Environmental Impact Assessment (EIA) legislation was first adopted in Greece in 1979. In the intervening 23 years, competent authorities, practitioners, and developers have gained considerable experience in the practice of EIA. A previous research study conducted for the European Commission indicated, on the basis of the quality of Environmental Impact Statements (EISs) produced, that overall the nations EIA system was performing satisfactorily. This research builds on the previous study by examining a considerably larger sample (72) of EISs produced for a diverse range of project types. Only 40% of EISs sampled were found to be of a satisfactory quality (compared to 75% in the previous study). An assessment of the performance of different elements of the EIA process indicates that descriptive tasks are, on average, performed better than scientific tasks. Consultation with stakeholder groups and their participation appears to be particularly problematic. Variables that influence the quality of EISs are identified and a number of broad recommendations are made for improving the effectiveness of the EIA system in the short and long term.

The Consideration Of Impacts Upon The Aquatic Environment In Environmental Impact Statements In England And Wales

Considerable research has been undertaken on the quality of Environmental Impact Statements as an indicator, albeit superficial, of the effectiveness of Environmental Impact Assessment (EIA) practices. Yet there remains a paucity of empirical data on practices at the more detailed level (e.g., for the consideration of certain environmental components and stages of the EIA process), despite the importance of such analyses for the development of grounded measures for enhancing effectiveness. This study contributes to the development of a detailed empirical understanding of EIA practices by examining analyses of impacts upon the aquatic environment (Water Impact Assessment (WIA)) for a sample of 50 development proposals in England and Wales. The research results indicate that WIA practices have improved over time, but a significant proportion of assessments remain unsatisfactory, and the quality of core elements of WIA (e.g., the consideration of alternatives and impact prediction) is particularly problematic. It is suggested that changes made to the EU EIA legislation have not significantly affected WIA practices in England and Wales. However, practices are not as problematic as research indicates is the case for ecological, socio-economic and cumulative impact assessments. Further strengthening the legislative provisions for EIA would partially address a number of specific problems (e.g., inadequate scoping and provision for monitoring). Nevertheless, a comprehensive and concerted strategy for enhancing effectiveness will be required if WIA is fulfil its potential for contributing to the management maxim of sustainable development.
