Analyse spatiale de l’évolution du risque de gel sur la vigne en Bourgogne-Franche-Comté
2019
The warming undergone by the global climate does not necessarily entail a decrease in frost risk in agriculture/viticulture. Since both plant and climate are likely to evolve under changing environmental conditions, plant vulnerability and the meteorological phenomenon (frost) should be considered jointly when assessing the evolution of frost risk. This study aims at documenting the spatial and temporal frost risk changes in the winegrowing subregions of Bourgogne-Franche-Comté. The period between budburst and the last spring frost occurrence date has been considered as the most vulnerable for grapevines. We considered a plant as being stressed by a frost event when the temperature drops be…
