Résumé
Given the complexity of the land use/land cover changes problem in which are involved different parameters (Environmental, Social, Economical…etc.), a multidisciplinary approach is mandatory to reach the state-of-the-art understanding. The DREAM model : Distributed model for Runoff, Evaporation and Antecedent soil Moisture simulation, is optimised and applied to model the effect of (LULCC) on water budget and to estimate stream flow discharges. With particular emphasis for the model parameters optimization and the spatio-temporal changes pertaining to LULCC. Processed LANDSAT images are used to analyse the changes in the land use, and MODIS Leaf Area Index images are used for model input to simulate the effect of land cover dynamic. In addition, a thorough investigation for the driving factors leading to LULCC. It includes Physical (climatic) and Human (economics and governance) driving factors. The study is conducted in the Celone at San Vincenzo sub-basin of Candelaro watershed in the Apulia region, Southern Italy. An area, as expected, offers great conditions for such study. Indeed, the watershed soil components demonstrate a high dynamicity. Synthesise linking and causals relations were mad for the different components involving within the Celone to drawn recommendations for the future governance and management of the area.
