Land degradation (LD) represents a threat for environment and human survival, triggered by initial conditions of environmental fragility and due to both natural and anthropogenic factors. Under evolving socio-environmental scenarios, this work proposes a D evaluation approach to quantify the role of the main LD processes in Italy: climate quality, soil erosion, salinisation, sealing, contamination and compaction. Through statistical methods and GIS tools, we derived six thematic indicators of vulnerability to each LD process, implemented a synthetic land vulnerability index (LVI) and analyzed the LD risk in Italy. Advantages of this approach compared to other methodologies were finally discussed.

Abstract
Land degradation (LD) represents a threat for environment and human survival, triggered by initial conditions of environmental fragility and due to both natural and anthropogenic factors. Under evolving socio-environmental scenarios, this work proposes a D evaluation approach to quantify the role of the main LD processes in Italy: climate quality, soil erosion, salinisation, sealing, contamination and compaction. Through statistical methods and GIS tools, we derived six thematic indicators of vulnerability to each LD process, implemented a synthetic land vulnerability index (LVI) and analyzed the LD risk in Italy. Advantages of this approach compared to other methodologies were finally discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
