For a long time, the growth of the EU was regarded as a unidirectional process. Brexit, however, has shown that integration can also be reversed. While the consequences of this disintegration process on the macro-level have been much debated, the impacts on the local level have mostly been neglected. This PhD project aims to analyse the local consequences of Brexit on Calais and Dover, which constitute the most important transportation link between the UK and continental Europe. An emphasis is put on spatial effects in the border region and the impacts on the lifeworlds of inhabitants. Methodologically, I plan to conduct an ethnographic study to collect data through interviews and participant observations.
