Volume V. 281 STRUMENTI CARTOGRAFICI PER LA LETTURA DELLE DINAMICHE PAESAGGISTICHE IN MICRO-AREALI A CONNOTAZIONE AGRICOLA * Mapping Tools for the Reading of the Landscape Dynamics in Micro-Areals with Agricultural Characterization Antonella Incognito Gianni Petino Università degli Studi di Catania, Italy Abstract. In the chosen territory, a portion of the territory of Belpasso and Paternò within the administrative boundaries of the province of Catania, on the slopes of Mount Etna, coexist different souls and different processings of the soil in an area that has a clear agricultural and citrus connotation. In this scenario, there is the issue of Citrus Tristeza 1 Virus (CTV) which allowed us, through a specific research project, to know the micro-areal, deepening some landscape issues since its presence is relevant to the detriment of the landscape aspects of local Citrus cultures. Over the last decade, the situation has greatly deteriorated in Sicily where numerous outbreaks were found in citrus species grafted onto sour orange trees in almost the whole region. The extent of the phenomenon “Tristeza” and the problems associated with it are certain, obvious and supported by a vast literature, instead languishing territorial approaches that take into account the land transformations and the consequent impact on the territory as a whole, that is the set of vertical and horizontal relationships and the objects and subjects that these relationships bind to each other and to the land, up to its landscape output. Keywords: landscape, agriculture, cartography Posizione del problema La partizione territoriale, da noi evidenziata e indagata, è stata selezionata attraverso l’applicazione di schemi funzionali omogenei, cioè attraverso i caratteri dell’omogeneità territoriale applicata e verificata nella copertura e uso del suolo, nella comparsa e nella diffusione del CTV e in ultimo nelle dinamiche territoriali, nel tentativo di verificare se le interrelazioni tra sistemi rurali e urbani possano essere considerate utili alla conservazione delle pratiche di territorializzazione 2 e ri-territorializzazione 3 in uso nell’area.

Among all, those of viral origin, like CTV, represent a huge threat to all citrus plants grafted onto sour orange trees. The term “tristeza” was coined by Brazilian farmers following the strong epidemic that affected South America in the late 30s of the last century. This citrus disease has worldwide economic relevance according to the serious problems it caused in Brazil, Spain and, more “recently”, in Italy; it is estimated, in fact, that CTV caused the death of more than 100 million citrus trees. 2 Tale pratica di suddivisione territoriale fonda la sua esistenza sul concetto di territorialità, qui intesa come rapporto dinamico tra componenti sociali (economia, cultura, istituzioni e
