Spatial Multicrierial Evaluation of Soil Consumption as a Tool for SEA

The paper represent a check of the use of multicriteria evaluation in order to add a qualitative evaluation to the traditional quantitative measure of the sustainability of soil consumption. The experiment starts analysing all deriving measure from measures of different typology of soil consumption and land use as criteria to evaluate which part of urbanised land is more expendable for land transformation. This application results quite interesting when utilised to create a set of indicators useful for Strategic Environmental Assessment (SEA), as instrument of measuring impact and of monitoring future urban development The work is subdivided at the urban scale in three different stages. The setting of measures, the creation of complex indicators as basis for evaluation criteria, the classification of priority n soil consumption. Results show the opportunity of densification inside existing settlements, but they extend the utility of the evaluation in profiling measures for tegional policies of containment of soil consumption.
