“Anti-Gravity Tourism Planning”: An Analytical Approach to Manage Tourism Congestion, Seasonality and Overtourism

Tourism today represents a strategic engine of economic growth, contributing substan-tially to GDP, employment, and export revenues. Accounting for approximately 10% of global GDP, the sector plays a significant role in tourism-intensive countries. Tourism has shown remarkable resilience and recovery capacity in the post-COVID era, reaffirming its status not only as an economic sector but also as a spatial phenomenon. Due to its inherent place-based nature, tourism cannot be outsourced: it relies on the unique cultural, en-vironmental, and territorial assets of specific locations. While this makes tourism a powerful driver of local development, it also presents challenges related to environmental stress, cultural commodification, and social tensions, especially in over-visited destina-tions such as Venice, Barcelona, or Lisbon. This paper introduces the concept of “an-ti-gravity tourism”, a novel framework inspired by physics, to describe planning strategies aimed at counteracting the gravitational pull exerted by mass tourism hotspots. Using the STESY model, the study applies spatial analysis to four case study areas, identifying Destination Areas (DAs) through clustering techniques and developing spatial design proposals aligned with the principles of the New Urban Agenda (NUA). The results highlight how “anti-gravity” strategies can be operationalized through context-sensitive planning tools to mitigate overtourism, support territorial equity, and maximize positive externalities. Ultimately, the paper argues for a paradigm shift to-wards tourism policies that ensure long-term sustainability by balancing economic growth with social inclusion and environmental stewardship.
