Multivariate Analysis of Socio-Economic Indicators as a Measure of Sensitivity to Land Degradation in the ESA Model

Luca Salvati, Marco Zitti


Understanding the interactions of bio-physical processes with demographic, social, and economic conditions in Mediterranean-type ecosystems was recognised as a crucial issue to fill efficient monitoring of sensitive areas to Land Degradation (LD). In this paper a simplified framework aimed at assessing the impact of specific socio-economic variables potentially accelerating LD was illustrated. Based on a wide indicator set, the framework was applied to a regional case study in Latium, central Italy. A synthetic index of land sensitivity to anthropogenic drivers of LD was developed through Principal Component Analysis. Incorporation of the index into a standard Environmental Sensitive Area (ESA) procedure was discussed. This will allow a more detailed evaluation of both bio-physical and socio-economic conditions determining land sensitivity to degradation.
