The second group, “Calabrina, Castione Marchesi-Tegagna”, is characterised by very clayey soils (Vertic Inceptisols or Vertisols), which are subject to water stagnation in certain periods of the year. Approximately 7% of these soils, or 2.5% of the entire municipal surface area, have been covered as a result of urbanisation. The “Monticelli” soils, which display the best agronomic qualities, have been spared by urban development. It is in fact possible to observe a sparse presence of farmhouses, whose number and extension have not changed significantly over the past century. Municipality of Sorbolo (Parma). Sorbolo is the smallest of the three municipalities analysed (3,927 Ha) and is situated in proximity to the Po River, between the provinces of Parma and Reggio Emilia. Here urban development has had the greatest impact, with the ratio of urbanised areas to total municipal land area rising from 1.18% in 1889 to 8.36% in 1990 (see Table 2). Urbanisation has mainly affected the “Sant’Omobono” soils: in this zone 16% of the available surface area has been developed, equivalent to 5% of total municipal land area. Sant'Omobono soils have acceptable agronomic qualities (Fluventic Inceptisols), as may be seen from the data reported in Table 1. From a pedological point of view, this territory is less differentiated than the municipality of Castel S.Giovanni. In addition to the "S.Omobono", the following soil types may be found (table 4). “Risaia del Duca- Medicina-Cataldi” soils are definitely clayey (Vertisols and Vertic Inceptisols), meaning that their structural conditions are susceptible to change due to climate factors. Here about 5% of the soil surface, equal to 3.5% of the total municipal land area, has been lost to urban development.

Situated in the western part of the province of Ferrara, Bondeno is the largest of the municipalities examined (17,514 Ha). As may be observed in table 2, the percentage increase in urbanised surface area is markedly lower than in the other two previously analysed municipalities. This is most likely due to the particular nature of the land, which has served to limit expansion and cause development to be concentrated in areas less prone to hydromorphy. From a pedological viewpoint Bondeno is characterised by the prevalence of “Risaia del Duca – Case Ponte” soils, made up of expandable, oxygen-deficient clay (Vertisols) and “Ruina-Stradazza” soils, which are silty and have poor internal drainage (Aquic Inceptisols).
Approximately 3.5% of the soil surface falling within the “Risaia del Duca – Case Ponte” delineation has been urbanised; this represents 2.9% of the total municipal land surface. By contrast, 8.2% of the available “Ruina-Stradazza” soil surface, representing about 2% of total municipal surface area, has been lost to urbanisation.

The method proposed involves a first stage in which a small-scale investigation is conducted with the aim of precisely identifying the changes that have occurred as a result of urbanisation over a specific period of time. The second stage consists in a large-scale qualitative and quantitative analysis (at a municipal level) of soil depletion in relation to the urban development recorded. The very fact that the defined study areas coincide with the areas of jurisdiction of the local authorities may enable an immediate implementation of land planning tools aimed at achieving a more judicious use of soil resources and preventing the most fertile soils from being converted to non-agricultural use and from being sacrificed, in particular, to urbanisation, insofar as this is possible.
