/ 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 pre-decisions stages of EIA was rated higher than in the post-decision 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 socio-political 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.KEY WORDS: science, environmental impact assessment, professional practice, monitoring, impact prediction, mitigation, decision-making
Science and Environmental Assessment
3A considerable amount of interest and attention has been focussed on the role of science in environmental impact assessment (EIA) and a substantial body of literature has addressed this topic. This paper reviews this literature briefly before presenting the results of a survey of 31 EIA practitioners in Western Australia. The principal aim of the survey was to determine what practitioners perceived that the role of science in EIA should be and to compare this with the positions established in the literature. The results of a survey of EIA practitioners in Western Australia are presented and compared with previous theoretical, empirical and survey studies of the role of science in EIA. The study provides valuable insights concerning the practice of EIA and what can be expected of the process. As the hypotheses underlying the study were derived from the literature on the role of science in EIA, it is useful to start with an overview of this body of work.Much of the literature can be classified into two main types:• studies of the theory and practice of EIA with respect to the role that science can or should play (eg. Beanlands and Duinker 1984, Shrader-Frechette 1985, Lemons 1994 A generic approach to EIA has been described by Sadler (1996, p18) which can be applied to any proposal put forward by a proponent.
