AB [EN] Spain accounts for 13.1% of the world’s vineyard area, and viticulture is crucial for the socioeconomic and cultural sectors.Vineyards are among the perennial crops that can suffer most negative impacts under climate change which can pose challengesto the sustainability of viticulture. Local and regional studies are needed to assess these impacts to help implementeffective strategies in response to climate change. To this end, our approach involves integrating both conventional agroclimaticindices and those new bioclimatic indices that have proven to be essential for the characterization and demarcationof vineyards into species distribution models to assess areas suitable for viticulture under climate change projections. Theproposed methodology was tested in a viticultural region located in northwestern Spain (DO León). An ensemble platformwas used to build consensus models encompassing three general circulation models, two emission scenario pathways and twotime horizons. Only the predictors that effectively characterize each grape variety were included in the models. The resultsrevealed increases in the continentality index, compensated thermicity index, hydrothermic index of Branas, and temperaturerange during ripening in all the future scenarios analyzed in comparison to current conditions. Conversely, the valuesfor the annual ombrothermic index and growing season precipitation may decrease in the future. The pattern of changes for2070 will be more pronounced than for 2050. A significant loss of future habitat suitability was detected within the limitsof the study area for the grape varieties analyzed. This negative impact could be counteracted to some degree with new andfavorable areas for the cultivation of vineyards in territories located at the north of the DO limits. We suggest that our resultscould help policymakers to develop practices and strategies to conserve existing grape varieties and to implement efficientadaptation measures for mitigating or anticipating the effects of climate change on viticulture.
