Abstract: Soil sealing may be considered as a negative externality of the economic growth, because the sealed soil loses several of its ecological functions. The analysis of land cover changes carried out by traditional data sources, allows only a relatively rough estimation of soil sealing, since it is a process associated, although with different rates, to both urban and semi-natural land use categories. The aim of this paper is to illustrate a sampling procedure quantifying the soil sealing rate over time in Italy. The procedure was based on the visual interpretation of 12,000 plots from aerial photographs and land cover maps at different times (1956, 1994, 1999, 2006). Results indicate that soil sealing was continuously increasing in Italy throughout the investigated period. The highest rate was found in northern Italy. The implications such dynamics have on planning strategies aimed at containing urban sprawl are finally discussed.
