Processi di periurbanizzazione nei paesaggi dell'olivo
2008
The urban sprawl in the agrarian territories of Sassari started more than twenty years ago, even
if the urban development is disciplined by urban planning.
In the essay we read the evolution of land use and land government, according to the plans at
different scales; furthermore, a diachronic analysis of land use transformations is done, to underline
the trends toward a sort of urban “dispersion” or “diffusion” (Indovina 1990), both residential
and commercial.
Such urban phenomenon is articulated in different areas, characterized by different ways of interaction
between residential (or commercial) and (residual and marginal) agrarian land uses. This
forms of interaction oscillate between two conditions: one is a sort of “olive trees and residential
landscape”, a unicum of interaction between the trees matrix and the settlement. This landscape –
in which the relationship with the environmental structure of the territory (the valleys system,
Monte Bianchinu, Monte Oro) is privileged– is opposed to the settlements superimposed to the
historical agricultural matrix (Li Punti, Predda Niedda), which dim it and determine non-structured
hybrid edges.
Between these situations, intermediate forms of interaction can be recognized; these need planning
rules ad hoc , that choose the most suitable “devices” to govern the urban phenomena and to
maintain the original landscape matrix.
