"Preservation of Centrality in Rural and Mountain Areas": Friuli-Venezia Giulia region has started the QUALIMA plan in order to evaluate the reduction of centralization that afflicts the greatest part of the mountain area. In this plan multi-activity appears different from the usual one (mainly agritourism and ground maintenance) since it aims at mantaining the sense of the place and its community. Therefore it aims, whenever economically possible, at the centrality, strengthening the survival of the commercial exercises and giving them the possibility to develop functions of reception and of public reference. Revisiting Christaller's theory of central places, which is well suited to these kind of problems, the authors have clarified the points of the theory that deal with the simultaneous presence of all the functions of a certain level, pointing out that in marginal areas supportability imposes its safeguard, unlike what is theoretically scheduled in reticular system theory. Simple models prove that at a low urban level this appealing model cannot psicologically operate (and perhaps not even economically).
