This chapter situates the informal camp as a vital space of contemporary migration, discussing it in relation to more formal settings and theorizing the role of political inaction in their spatial politics. The chapter starts by highlighting different formations of the informal camp; from adjunct encampments near formal refugee sites; to urban squats in transit cities; to the widespread prevalence of ‘jungles’ as important spatial formations for people on the move. Placing this varied constellation of camps within the wider European context, the authors conclude with a detailed discussion of one such informal camp: the Calais ‘jungle’ in Northern France. Although campscapes are significant spaces for political geographers, a more sustained analysis of camp informality is needed to recognize the important role that unofficial camps play in processes of displacement and migration. The authors suggest that geographers look beyond the confines of formal camps to appreciate the wider role that encampments play in migration processes and the contested production of ‘bare life’.
