Closure in risk debates: Pre-assessment of Finnish forest biotechnology

The aim of this paper is to contribute to a more systematic and integrative pre-assessment of risk. The paper argues that although there are many insights into 'pre-assessment' within the field of risk studies, it suffers from a lack of robust methodological tools and approaches. A problem with the neglect of such approaches is that factors that set the stage for further steps in the risk-handling chain can remain in a state of implicit assumptions, impose biased interpretation of relevant risk issues and mislead the consideration of active intervention options. The suggestion of this article is that 'social arena analysis,' combined with the identification of 'closure mechanisms,' can provide a practical and theoretically anchored tool for the pre-assessment of risk. The value of this approach is demonstrated through the analysis of a debate on the future and risks of Finnish forest biotechnology, and in a final discussion on policy options emerging from the analysis.
