The multidimensional nature and dynamic transformation of European borders and internal security

The introductory chapter provides a brief overview of the current political and operational challenges faced by the European Union in internal security. We are confronted with an unprecedented degree of controversy, politicization and pace of change with regard to migration and border security issues, while other internal security concerns, such as the fight against terrorism, remain on the agenda. The chapter then turns to the possible consequences of such transformation for academic study, and proposes an analytical focus on practices and diverse sites of implementation, as opposed to the traditionally dominant concern with policy-making dynamics in Brussels. In this context, we refer to borders and bordering processes as multi-dimensional phenomena that permeate spaces within and beyond the territory of the EU. Finally, the introductory chapter elaborates on the three organizing themes of technology, externalisation and accountability, which provide a fruitful cross-cutting, perspective on the increasing empirical complexity of the EU’s Area of Freedom, Security and Justice. Finally, each individual contribution to this volume is shortly reviewed under these three respective headings to support mutual dialogue and point out further research perspectives.
