Today, tourism is one of the fastest-growing sectors globally and plays a decisive role in the economic development of countries. In recent decades the Yucatan peninsula has undergone great transformations connected to an uncontrolled and unrestrained tourism development. Multinationals and financial capital more and more interfere with national organizations and policies, under the banner of increasingly globalized tourism generating cultural models and lifestyles that risk emptying these contexts of functions and typical activities, distorting traditions, culture, and local identities. The paper is the result of a study carried out in south-eastern Mexico. The study investigates the other side of tourism, in an attempt to highlight the aspects closely related to the intensification of the tourism phenomenon and a low attention to the management of resources.
