Favorability Level Analysis of the Sevastopol Region's Climate for Viticulture

The harvest and quality of vineyards are determined by the climatic conditions of the region. Viticulture is a promising avenue in the agricultural sector of the Sevastopol region. In this study, we provide a comprehensive analysis of the orographic and climatic conditions and microclimate zoning to optimize the placement of vineyards. Meteorological data (air temperature and precipitation) for the period 1985-2018 were used to assess heat and hydration conditions and to calculate agroclimatic indices for a comprehensive evaluation of the effects of the observed climate change on viticulture. The observed upward trends in heliothermic indices and downward trends in precipitation change the conditions and cause a shift in grape-suitable zones. Based on heat supply and frost resistance, microclimatic zoning of the territory was carried out and 13 ecotopes were identified, for each of the grape varieties that were recommended. Our study indicates that the agroclimatic conditions of the Sevastopol region make it possible to grow grape varieties from very early to late ripening.
