How much can a virtual territory help us to understand the resilience of the heroic viticulture? A case study in Trentino (IT)

Résumé En

In Trentino (IT) two types of vineyard landscape coexist in dynamic equilibrium: the valley is mechanized and plots have a great extent, on the steep slopes a terraced viticulture developes with small size plots and little mechanization is possible. In this work we assume that the emergence of two different contexts-steep slopes and the valleys-result from the complexity of the processes that underlie the development of a territory, and the different factors in play should be studied in their intrinsic diversity because none of them should be considered as the main cause of the emergence of the landscape structure. With some simple (but not simplistic) assumptions on the landscape structure the authors developed a parsimonious agent-based model for the simulation of these dynamics. The results obtained were compared with the historical evolution of the landscape documented in historical archives and with the current state of the territory. The goal is to determine the plausibility of such a simplified model that can describe the evolution of the landscape to the current configurations. We will show, finally, the representations of the model and the dynamics of two viticultural landscapes of the Trentino region (IT).
