Abstract

In recent decades the clearing of Mediterranean maquis along with the creation of new pastures has been a major factor of land degradation in Sardinia (Italy). Consequently, tillage and water erosion intensified over a wide area. This work assesses the impacts of land use change on soil properties in a representative area of central-eastern Sardinia. Paired forest and pasture sampling sites were selected in relation to present land use, land suitability, and land use history. Different soil properties were considered: physical, chemical, biological, and micromorphological. The comparison of forest and pasture soils showed a significant soil loss (in terms of soil thickness), and a clear decrease in organic carbon storage. An increase in bulk density and a change in microporosity and its vertical distribution were also observed, respectively by field measurements and micromorphological quantification on digital images
