Climate change impacts on grapevine - Iñaki GARCIA DE CORTAZAR-ATAURI

Wine grapes (Vitis vinifera L. ), as other perennial species, are especially sensitive to climate change, with potential effects on yield, quality and economic viability. Since grapevine has been cultivated, specific growing regions were established, whose climatic conditions played a decisive role in the development of typical wines from specific varieties and cultural practices. Many reports show that the major impact of CC on grapevine would affect phenology (an advance of 10 to 30 days for any stage of development). Moreover, whereas some new regions in the North of France could become suitable for viticulture,  in the South of France hydric comfort of plants would be reduced, with negative impacts. Ripening would occur under much warmer conditions than today, with major impacts on berry content and its suitability to elaborate the current types of wines.
The objective of this presentation is to present from some examples the impact of climate change on grapevine observed during the last years and expected for the future.
