Reorganize the vineyard at a local scale
In the new climatic context, winegrowers will have to rethink the location of grape varieties and agronomic practices. This strategy can operate within the same local space, a "terroir". This has internal climatic variability, linked in particular to its topography, which can become an asset!
Observations carried out on several sites equipped with temperature recorders show that from one plot to another, average temperature variations over the vegetative period of the vine can reach 2 ° C, i.e. a variation greater than the increase in temperature. expected by 2050.
In Banyuls (66), the vineyard spreads out on a terrace along the Mediterranean coast up to an altitude of 500 m. Average temperatures are higher at the bottom of the hill leading to drops in acidity which affect the quality of the wines. Wine growers can then seek to replant their vines at a higher altitude, which implies new land transactions and risks upsetting the current landscape. Collective work was carried out around simulations to organize the plantations and maintain the quality of the wine and the landscape.
In the Layon hillsides (49), temperature differences are also observed depending on the exposure of the plots, prompting winegrowers to replant early varieties, such as chenin, rather at the bottom of the valley or to choose more resistant rootstocks. to drought for plots on the hillside.
