"Objectives: The aim of this paper is to show the approach, methodology and results of a study carried out titled "The current situation of high mountain villages which has lost population". The motivation of the research was to guide intervention actions of Catalonian government with the objective to protect and revitalize the architectonic and scenic patrimony of the Pirineu. Without doubt, the phenomenon of underpopulated mountain villages is the direct consequence of the transformation of agricultural models of production (Tulla 2004). One of the consequences of the globalization has been the divulgation, enlargement, generalization and incorporation of the typical city life styles into the rural world. This phenomenon generates dynamics of metropolitanization at micro level, which contrast with the phenomena of city explosion (Font, Indovina, Portas i Ascher, 2004). Because the explosion of small cities has implied better services and quality of life, this situation has accelerated that small rural nucleus lose population. At the same time, some studies reveal that a change of interest have occurred relating to the maintenance and restoration of a patrimony which has not been valued whereas people live in. This new situation offer new expectative for revitalization and interest for reoccupy these rural settings. Using urban, socio-economical and psycho-environmental indicators, 95 rural settings of high mountain where studied. In order to gather the information, interviews to the representative habitants of the villages as well as observational techniques were used, generating a card file for each setting. The results of the research have made evident the relevant role of individual and social behaviours in the processes of consolidation, recuperation or degradation of the architectural and environmental patrimony of these settings. In general terms, the human influence has been more relevant than the geographical conditions or than the effects of the public policies. The findings make relative the initial hypothesis which gave priority to economical, territorial and formal factors (such as location, sights, transportation facilities, proximity to more important nucleus). Thus, the current state of some rural village as well as the future recuperation of others depends on attitudes and values of their habitants, of their initiatives and the ecological responsibility assumed by most of them.
