By critically assessing the opportunities and challenges posed by planning and governing at the megaregional scale, this book examines the latest conceptualizations of trans-metropolitan landscapes. In doing so, it seeks to uncover whether megaregions are a meaningful new spatial framework for the analysis of cities in globalization. Situated within the broader contours of global urban analysis, the book draws together a range of thought-provoking contributions from scholars engaged in the study of trans-metropolitan regions. It thereby provides multiple paths of access for those wishing to familiarize themselves with this topical area of global urban studies
