Border-regional resilience in EU internal and external border areas in Finland

European border regions have witnessed a long history of remarkable mobility shocks stemming from complex ecological and economic changes and geopolitical events. The experience of near-continuous regional and global crisis has increased interest towards the idea of resilience, that is, the ability of communities and regions to adapt and cope with disturbances and transitions. Inspired by the literature of regional resilience and the evolutionary approach, this paper will examine the difference that borders and geopolitical conditions make from the perspective of regional resilience and especially ‘border-regional resilience’. Particular focus will be on irregular cross-border mobilities and consequent transitions in EU external and internal border towns, here the Finnish towns of Lappeenranta and Tornio. The study points out that the geopolitical environment and the openness of the border partly determine the regional development trajectories and the ways of coping with cross-border mobility-related changes. Although the border location entails some vulnerability, formal and informal cross-border institutions and relations of trust are of crucial importance from the perspective of border-regional resilience. The paper proposes a research agenda for studying border-regional resilience in the context of environmental, economic and social changes and geopolitical events.
