Investigating land-use dynamics worldwide has revealed that one of the most significant
socioeconomic processes is the progressive decrease of surface area intended for
agricultural use. Land loss is accompanied by the increase in both artificial areas, wooded
areas and semi-natural environments and a parallel decrease of cropland. Two kinds of
urban growth exhibit very different soil consumption rates and characteristics. Compact
growth involves almost total saturation and natural soil sealing; conversely, a dispersed city
is characterized by the coexistence of buildings and green areas, which guarantees a
partial persistence of natural features. Soil consumption is only partly related to
demographic growth in Italy. While trends in resident population in Italy have stabilized
since the 1980s, soil sealing was growing at a high and almost constant growth rate over
time. The intensity of use, i.e. the ratio between the number of inhabitants and the sealing
surface, represents an effective indicator for assessing settlement types. The systematic
analysis of how much soil is consumed, combined with the evaluation of the quality and
uses that the soil itself had before being transformed, is an indispensable element to
support decisions in the sphere of land policy.
