Abstract

Thanks to the reconstruction of agro-pastoral land use of a territory, it is possible to obtain much information, both of an ecological nature, and about the populations. By the reconstruction of these dimensions of a community it is possible to understand not only the aspects linked to the exploitation of a territory, the subsistence and demography of a given group, but also more generally the group’s social organization itself. With a series of GIS tools, capable of applying the FAO’s land evaluation techniques, it has been possible to generate a predictive raster model of the landscape with the degree of agro-pastoral suitability inside each cell. Thanks to this model, the agro-pastoral exploitation of a territory can be simulated, calculating the food production of each settlement, as well as the consequent demography maximum sustainability. Thanks to the identification of specialized productions sites and of settlements capable of producing a ‘surplus’, or vice versa ‘not-self-sufficient’, it will be possible to articulate socio-political models, hypothesizing exchange networks or relationships between the different sites. The text illustrates in detail the structure and functioning of the developed model, as well as its applications in the archaeological context of the ‘Ager Tarquiniorum’ during the Final Bronze Age.
