Abstract

Anthropogenic soils created ex novo by land-us e change in large scale farming are, from a pedogenetic point ofview, catastrophic events that bring the soils to time zero and change the natural pattern of the soilscape,remarkably, in some cases.The qu antitative aspects of pedodiversity of a soilsc ape in South-East Sicily, where some types of soils, inrecent decades, have suffered a consistent reduction due to the transformations by large scale farming, areconsidered. The evolution of pedodiversity over a 53-year period (1955 to 2008 ) is examined using adedicated statistical method and a space – time model based on Markov analysis and cellular autom ata in orderto predict the evolution of the soilscape pattern in the next 42 years (i.e. until 2050). Soil subgroups, using theUSDA Soil Taxonomy and a classi fi cation proposal, were considered and the followi ng indices were used:richness; Shannon's diversity index; Simpson diversity index; modi fi ed Simpson 's diversity index; Shannon'sevenness index; Simpson's evenness index and m odi fi ed Simpson 's evenness index. These indices measuredover time, show, quantitatively, a decrease in pedodiversity that highlights the effect of the humanintervention in modifying the natural order of the soilscape
