The distinctions between tourism and migration are increasingly blurred. Tourism often drives various forms of mobility, and an international workforce is essential to maintaining functioning tourism economies. This book explores intersections of tourism and migration, considering their relationships with and impacts on social sustainability. The chapters explore in a variety of contexts how the planning, development and governance of tourism affects the sustainability of communities, which consequently influences attitudes towards migrants and tourists. They also consider how migrant-local connections may evolve, creating opportunities for positive, symbiotic co-existence or intergroup tensions and exploitative relationships. The book paves the way for future work examining new forms and interactions between migration and tourism that contribute to social sustainability.This book will be of great value to students, academics, and researchers interested in tourism, geography, migration/diaspora studies and sociology. The chapters in this book were originally published as a special issue of Tourism Geographies.
