ABSTRACT: This chapter develops the conceptual and methodological framework of Naturbanization. In synthesis, the author designates as naturbanization the attraction of populations towards places whose natural values are known, and to the analysis of the territorial and land-scape changes to which this gives rise. Naturbanization begins from the attraction that protected natural areas exercise towards a section of the population which wishes to live, work and enjoy its free time in surroundings with a high environmental value. This behaviour is a part of the de-concentrated model designated thirty years ago as counter-urbanization. While counter-urbanization analyses the changes in the mobility of the population and the behaviour of the urban population, naturbanization puts the emphasis upon the territorial consequences of these changes on the influence area of protected areas. Naturbanization intends to develop a proper integration of the population into the landscape and environment within adequate land use planning decisions for the management and control of protected areas.
