This open access book offers the first comprehensive global overview of urban and local initiatives, policies, and practices towards including and protecting migrants in vulnerable situations and refugees. The chapters in this volume illustrate the various urban solidarity practices in different world regions, while highlighting important differences arising from geographical, political, geopolitical, economic and demographic contexts. The volume contains a mix of chapters that present comprehensive and state-of-the-art literature reviews and the results of empirical case studies that offer original regional perspectives of migrant and refugee inclusion and exclusion, and the policies, politics and rights of urban solidarity.
