I started out in Chapter 1 by saying that this book is about how we talk about the environment, why we talk about the environment in a certain way, and some of the effects of doing so. It has not been my ambition to explain all aspects of the management of marine living resources, nuclear safety and industrial pollution in the European Arctic. It has been my ambition, however, to explore how discourses ‘define the range of policy options’ (Litfin 1994) in these issues. How are the borders defined in the three case studies of what is to be perceived as legitimate knowledge, actor (including national) interests and institutional arrangements? In this discussion, I have drawn partly on Litfin’s (1994) conception of how knowledge is brokered by different people and groups, partly on Hajer’s (1995) ideas of story lines and the positioning of subjects, and, to some extent, also on Dryzek’s (1997) categorisation of various environmental discourses. My major focus has been on the embeddedness of environmental discourses in more overarching discourses in society (Neumann 2001).
