"The role of agricultural activity in the evolution of the scenery" The Italian scenery is greatly due to agriculture's work of centurise as, considering also the pastures, it includes at least threee quarters of the land. On the other hand the incidence of the urban and industrial structures and of the infrastructures, even if considerable, doesn't superate 10% of the land. In this analysis there are two important oppositions. The first is between synchrony and diacrony, that is the structure of the present hic et nunc and the historical trend that has brought to such a present. The second is the distinction between the study of the general models on the one side and the analysis of the differentiations and of the particular causistry on the other. In this paper the first and the second section are diachronic, the first historical, the second featuring models, while the first section is synchronic and deals with the contributions that agriculture will be able to give to the future acolution of the scenery.
