Viticulture in southwest Germany under climate change conditions

摘要

We estimated changes in viticulture conditions over the 21st century in Baden-Wurttemberg, southwest Germany, using scenario runs of 3 regional climate models for 19611990, 2021-2050 and 2071-2100. The scenario runs were compared and validated with local observational data. By applying the Huglin Index, possible expansions of areas suitable for viticulture, as well as suitable grape varieties for the region, were determined. Optimal grape varieties are changing to those more suitable to a warmer climate. This development was found in all examined simulation runs.
