Impacts of climate change on grapevine: the use of crop model WinStics to estimate potential impacts on grapevine(Vitis viniferaL.) in Sardinia scale

The vine has been extensively studied in the context of climate change studies. In this study an analysis of the potential impacts of climate change on grapevine (Vitis viniferaL.) will be presented. Namely predicting the responses of two main Sardinian varieties - Cannonau and Vermentino, in order to ascertain reliable adjustment cultural practices as well to define possible mitigation strategies. The objectives of this research were to evaluate the effects of climate change and grapevine and phenology, at two experimental sites in Sardinia, different for soil, climate conditions. To achieve these main objectives, the approach used in this study was: The application and assessment of a coupled climate scenario-crop model method, in which Atmosphere-Ocean General Circulation Models, used to generate future climate scenarios, are integrated into crop models to simulate future crop yields. The analysis of daily meteorological variables for current climatic conditions and climate change projections. These data are used as input variables for crop simulation models in conjunction with soil parameters and agronomic and management information, to simulate the dynamics of plant growth and development. The comparison of the results of these simulations for both current and future climatic conditions. Impacts of climate change are then expressed as changes in crop productivity and phenological phases.
