Assessment of hydro-erosive processes in small steep coastal basins in Liguria and Sicily, Italy

Risultato della ricerca: Other

Abstract

The steep Mediterranean catchments underwent drastic socio economic changes in the last decades.Moreover, these basins are also subject to climate variability and potential future climate change effects.Due to mechanization in agriculture a lot of surfaces changed from terraced vineyards and olive growthto abandoned land. The terraced areas are less productive and more cost and labour intensive andhence cannot compete with a highly mechanized agriculture. Furthermore, tourism based on the naturaland cultural heritage of the region is more and more important for the income of the inhabitants. Theabandonment has effects on the entire landscape system in terms of hydrological dynamics, sedimentdynamics as well as soil characteristics and the terraces itself. These changes are leading to a succession invegetation, destabilization of slope systems, and changes on the runoff and sediment discharges leadingto disasters such as the Vernazza event on the 25.10.2011 or the Messina event on the 01.10.2009. Inthis study, we present a comparison between the two mentioned areas located respectively in Liguriain the Cinque Terre National park (World heritage site-UNESCO) and in the Messinean area, Sicily (Italy)and a test of transferability aimed to assess debris flow susceptibility. In the framework of this researchextensive fieldwork, remote sensing and terrain analysis have been performed in order to parameterizeboth stochastic and physically based models. Moreover, few attempts of reproducing extreme eventshave been made. The results show that these Mediterranean catchments are highly sensitive to changesin landuse and climate. Hence, the study contributes to the understanding of landscape dynamics underglobal change conditions.
