Abstract
Italy is one of the Mediterranean countries that are menaced by desertification,
particularly in the Southern regions: Sicily, Sardinia, Apulia, Basilicata and the
Ionian areas of Calabria. In such a scenario it is evident that correct water
resource planning is very important: reduced water resources, once considered
meaningless, have now acquired notable importance. Environmentally Sensitive
Areas (ESAs) [1] to desertification will be described in this paper, with particular
reference to the Calabria region. Key indicators for the estimation of soil
capacity to resist degradation processes will be found through the MEDALUS
methodology (MEditerranean Desertification And Land USe: European
Commission, 1999), which allows the assessment of desertification risks on a
regional scale. Indicators will be grouped into four classes, on the basis of soil
quality, climate quality, vegetation quality and management quality. Each index
will be classified into three levels (high, moderate and low) according to the
MEDALUS classification, and they will be entered into and employed by a
Geographical Information System (GIS), which will define the different layers
depending on the quality index considered. In this way, the contribution of each
quality index will be defined and intervention and mitigation proposals will be
developed through the description of the main sectors (soil protection,
sustainable management of agricultural resources, decreased impact of
production activities and territory re-equilibrium), allowing the definition of
criteria used to limit the effects of the degradation and to allow correct land use.
1 Introduction
In Italy, desertification does not mean that landscape will turn into a desert one,
but that it will be characterized by aridity, erosion, salinization, depletion of
