Book excerpt: Border walls, shipwrecks in the Mediterranean, separated families at the border, island detention camps: migration is at the centre of contemporary political and academic debates. This ground-breaking Handbook offers an exciting and original analysis of critical research on themes such as these, drawing on cutting-edge theories from an interdisciplinary and international group of leading scholars. With a focus on spatial analysis and geographical context, this volume highlights a range of theoretical, methodological and regional approaches to migration research, while remaining attuned to the underlying politics that bring critical scholars together.
