"Tourists go home" rang true in Barcelona as residents objected to the excessive volume of guests generating inflation, congestion, and limited resources. Although overtourism is not new, Barcelona's latest forceful approach has attracted notice all around.

Travel accounted for 10.4% of the world's GDP before COVID-19, somewhat declining to 9.1% last year. Barcelona's €12 billion tourism income has resulted in growing living expenses and other problems for citizens even with economic gains. "The spiraling numbers of visitors taking a toll on cities, landmarks, and landscapes," National Geographic writes about overtourism.

Using water cannons, 3,000 residents of Barcelona's Neighborhood Assembly for Tourism Degrowth staged demonstrations demanding limits on hotel accommodations, fewer cruise terminals, and an end to publicly sponsored tourism advertising. Mayor Jaume Collboni raised tourist charges and promised 10,000 house for residents.

Removing bus #116 from Google and Apple maps will help to ease traffic by sending visitors to Antoni Gaudí's Park Güell.

Similar problems beset other popular tourist destinations. In Japan, a declining Yen and congestion have caused communities like Fujikawaguchiko to restrict visitor activity. Starting April 2024, Venice intends to charge each individual €5 admittance fee. Greece, New York, and Amsterdam are implementing policies meant to strike a mix between local welfare and tourism.

Professor Tyler Cowen of economics advises increasing costs to manage crowds and please residents while preserving economic gains. For visitors, who often find themselves in this once-in- a-lifetime chance, this begs the issue of fairness. The difficulty still is juggling the social and financial effects of overtourism.
