Abstract: Climate warming allows invasive pests to establish in areas where they have not been recognized before. Since its introduction in the 1950's in southern France, grapevine 'flavescence dorée', a quarantine disease of grapevines, has spread significantly in Europe and has first been detected in Austria in the southeast of Styria in autumn 2009, which currently marks the Northeastern border of its extension. VitisCLIM, a project funded by the Austrian Climate and Energy Fund, started in April 2011 and aims to model the current and future potential distribution of the disease and its vector, the leafhopper Scaphoideus titanus, in Europe under the influence of climate change. Vine growing areas of high risk in Austria will be defined. Based on scientific literature and empiric studies, an epidemiological model will simulate the temporal and spatial dynamics of the spread of the disease and its vector. Sensitivity analysis will determine critical parameters, including different management strategies which have an impact on the dynamics of the spread. The spread model, together with the results of a survey on direct and indirect costs will then be used in Input-Output Analysis to model the potential economic impact of 'flavescence dorée' to Austrian viticulture and related economic sectors. The results of the project will be communicated to stakeholders, risk managers, policy makers.
