Temporal Dynamics of Land Values and Determinants

The temporal evolution of land values is conditioned by the reference macroeconomic framework and, more strictly, by the socio-demographic and productivity characteristics of the territorial study area. If these dependencies are widely recognized in the literature, on the other hand, the correlation levels between the variables at stake, especially in relation to the parameters of the survey area, are not investigated in quantitative terms. With the present paper, we intend to establish the measure of the diachronic correlation between market values of the land (vineyards, olive groves and irrigated crops) and variables able to affect the mechanisms of price formation. Geographic Information Systems (GIS) are used for the processing of cartographic representations useful for visualizing the spatial distribution of data, which pertain to the vast area of the Province of Salerno (Italy). Correlation curves return the measures searched for the time interval from 2000 to today, allowing to highlight the effects of the structural crisis in the years after 2008. The entire analytical path starts from the collection of information and construction of the datasets, passes through the selection of parameters and for the processing of the maps and can establish quantitatively the levels of correlation between market values and territorial variables. Thus, it provides useful elements for future research, aimed at defining an explanatory model of the temporal trend of mercantile appreciations of agricultural soils.
