As the literature on environmental security has evolved and widened, knowledge of the full range of potential consequences of environmental change for different societies remains scattered. This article contributes to a more comprehensive approach to the implications of environmental change by providing a three-level framework of the security impacts. In particular, it will address gaps in knowledge by pointing out the relevance of geopolitical and structural factors behind environmental security impacts. The article will focus on the cases of two countries, Finland and Sweden—both seen as stable, high-income democracies that are well equipped to adapt to climate risks. Yet even under these conditions, preparedness to threat-prevention will not follow without a recognition of the full range of risks, including ones that are linked to socio-economic and geopolitical factors. On the basis of the Finnish and Swedish cases, the article proposes an analytical framework of three categories of environmental security impacts: local, geopolitical and structural.
