ABSTRACT
Desertification, or degradation of arid areas, is nowadays widely recognized as a major environmental problem that can severely compromise the sustainable development of the Mediterranean area. This process, often considered as a problem concerning developing countries, also involves developed countries and it is known that arid and semi-arid environments cover 40% of global earth surface where 1 billion human beings live. After the analysis of desertification indexes, this paper considers a prone area in Calabria region and proposes a parametric procedure defined IDEAs (Identification of Desertification with Environmentally Sensitive Areas) based on the MEDALUS approach in an area of the upper Ionian sea territory (Villapiana municipality, Calabria Region, Italy). This procedure exploits the ESAs methodology having the peculiarity that it gives a solution independent from the number and information layers that constitute the base layer. The model evaluates some quality indexes (climate, soil, vegetation and management), each evaluated as a function of the different base indicators considered that, being representative of the different erosion processes (such as erosion, evapotranspiration, drought resistance), help to define desertification in the study area.
