Paesaggi terrazzati in Costiera triestina tra problematiche di abbandono ed ipotesi di rivalutazione turistica

Land use changes, human activities (deforestation, agriculture, urban sprawl, ecc.) and abnormal weather events are the common reasons of hydrological problems like floods or landslides. Neglecting the terraced landscape, for example, reduced several times the drainage capacity of the water network surface, increasing the hydrological risks. In this paper we study terraced agricultural system of two villages (Prosecco and Contovello) near Trieste. First at all, we gave a detailed description of this rural landscape. Then, we applied a GIS analysis in order to evaluate main changes in the last forty years, overlaying not homogeneous cartography sources (aerial IGM photos of the 1974 and current ortophotos). So, we identified neglecting processes and reforestation dynamics of this terraced landscape. In a restyling perspective, we identified main local tourist attractions. Finally, we hypothesized a pathway aimed at sustainable tourism.
