This timely handbook examines the most contemporary, controversial and cutting-edge issues related to the involvement of volunteers in the fields of events, sport and tourism. Split into thematic sections, the primary areas covered include: key disciplinary approaches to understanding volunteerism, international contexts, managing volunteers, the impacts and legacies of volunteering and future trends in these sectors including online and digital volunteering. Commonalities and differences of volunteering in these sectors are drawn out throughout the volume. A diverse range of case studies are examined including the 2007 UEFA Under 21 Championship hosted by Poland, the development of the Appalachian National Scenic Trail, the Vancouver, London and Pyeong Chang Olympic Games, Belgium’s National Day in 2019, the Puffing Billy railway in Australia, as well as many other examples looking at destination services organizations, museums, grassroots associations, corporate events, community events and visitor attractions. Drawing on the academic and practical expertise of over 50 authors from across the globe, the handbook provides an invaluable resource for all those with an interest in volunteering in these sectors, encouraging dialogue across disciplinary boundaries and areas of study in order to advance volunteering research and practice in the fields of events, sport and tourism.
