Step 1: Define Geography of Tourism. This field of study examines travel and tourism as an industry and a social and cultural activity. It looks at the spatial distribution of tourist activities, their economic impact, and their relationship with the environment.
Step 2: Analyze its relationship with other sub-fields. While tourism has social, cultural, and urban aspects, at its core, it is a major global industry involving services, transportation, and finance. It is studied primarily for its significant economic role and impact on places. Therefore, it is most closely related to and often considered a part of Economic Geography.
