Abstract:
The Project is structured in four workpackages (WP): (1) Identification of homogeneous areas, (2) Climatic change, (3) Optimization of water resources and (4) Scenarios analysis. Starting from informations deriving from WP1 concerning two area located in Southern Italy (Apulia and Sicily regions), WP2 will provide temperature, precipitation and radiation scenarios according to several forecasted of greenhouse-gases emission by using the General Circulation Models (GCM) and to estimating local weather forecast for several decades at daily scale comparing two method of downscaling. Within the WP3, several researches at field scale will be carried out to investigate for the optimization of several irrigation variables using water resources of different salinity and quality. An other important issue of this WP will be to parameterize the simulation models about crop growth and photosynthesis translocation, soil water fluxes and solute transport. With the conclusive WP4, using the information deriving from previous WP, simulations will be effectuated at field and regional scale by using numerical models for simulating crops and cropping systems in order to evaluate the effects that the future climatic scenarios will have on crop yields and to individuate the best agronomical strategy to optimize the use of water resources.
