Arcview shape file format. The various layers were then assembled on a scale of 1:50,000 for printing. The second stage of the study entailed the extraction of data relative to the urbanised surface area for each period and each municipal territory. These data were then overlaid on the soil map derived from the database of the region of Emilia- Romagna, with soil types classified according to the FAO-UNESCO method. The database associated with the new overlay maps allowed a calculation to be made of soil depletion in relation to pedological type and urban expansion. Evaluation of soil depletion due to urbanisation The results of the analysis conducted on three municipalities, Castel S. Giovanni (Piacenza), Sorbolo (Parma) and Bondeno (Ferrara) are presented here by way of example. Soil delineations were defined for each, along with the agronomic features of the soils present (table 1). By overlaying the maps relative to urban expansion on the pedological data it was possible to quantitatively and qualitatively assess the soil depletion for each municipality analysed. Municipality of Castel S.Giovanni (Piacenza). Castel S.Giovanni is a small municipality (4,260 Ha) situated northwest of Piacenza. The urbanised area has expanded considerably over the past century. In 1889 it represented 2.6% of the total municipal land area, but by 1990 this value had risen to 8.6% (Table 2). Table 2 - Soil depletion due to urbanisation in the municipalities of Castel S. Giovanni (Piacenza), Sorbolo (Parma) and Bondeno (Ferrara), expressed in Ha and as a percentage of the total municipal land area. Municipalities Total surface area Urbanised surface area (Ha) (Ha) 1889 1955 1990 Castel S. Giovanni (Piacenza) 4412 113 (2.6%) 119 (2.7%) 371 (8.6%) Sorbolo (Parma) 3927 46 (1.2%) 82 (2.1%) 329 (8.4%) Bondeno (Ferrara) 17514 178 (1.1%) 267 (1.5%) 811 (4.5%) From a pedological point of view, the municipal territory is characterised by soils that differ both in taxonomic terms and in agronomic quality. Based on indications provided by the Region of Emilia-Romagna, the following soil delineations may be identified (table 3). The soil delineations most greatly affected by urban development (Fig.2) may be divided into groups according to the types of soils present therein. A first group “Barco-Cittadella-Ghiardo-Rivergaro” is characterised by decarbonated leached soils (Alfisols) with frequent deep gravel layers. From a mechanical standpoint they are well suited to bearing heavy structural building loads; approximately 20% of these soils, equivalent to 5.6% of the entire municipal land surface, have been turned over to urban development. 210
