Description :
This paper illustrates a procedure aimed at estimating diachronically soil sealing in suburban areas by using cartographical and statistical data. The procedure was applied (1949-2006) to the metropolitan area of Rome. Random sites were chosen encompassing the entire investigated area and evaluated in terms of sealing condition in 1949, 1990, 1994, 2000, and 2006. Although resident population has been found quite stable since 1970s, the sealed surface area grew rapidly from 8% in 1949 to 26% in 2006. The sealing status of each site was found correlated to the distance from the city centre, while not correlated to the distance from the major roads, railways, and the boundaries of the neighbor protected area. These results suggest that soil sealing in Rome was associated to recent processes of urban sprawl.
