Since the launch of Tourism Geographies in 1999, annual international tourist arrivals have surged from 664 million to 1.4 billion, with greater numbers of domestic tourists traversing within borders. Transportation improvements have made travel more efficient, affordable, and accessible, while the digital revolution has introduced social media, the sharing economy, GPS technology, and artificial intelligence to travelers. This forward-thinking collection offers the latest research in tourism geographies, drawing from a collective body of work developed over the last quarter century. During this period, the subfield has evolved from a convergence of geography and tourism studies into a critically engaged, multidisciplinary branch of the social sciences. With roots in social and cultural geography and cultural studies, tourism geographers offer a critical approach to tourism studies, which foregrounds the role of place, space, people, and the environment. This collection illustrates how contemporary tourism geographies scholarship has built on this critical foundation to transcend the disciplinary walls of geography. Tourism geographies has long existed on the verge of disciplinary borders, accounting for the broad range of scholars and scholarship from social science disciplines such as sociology, anthropology, history, environmental studies, and planning, among others. This collection provides essential frameworks for foundational and emerging themes in tourism geographies, deepening understandings of tourism discourse and practice and setting the stage for the subfield's next act.
