L'impact du changement climatique sur la viticulture en France Méditerranéenne

Crop models have been used to evaluate the impacts of the climate change on the phenology and the quality of the grapevine Vitis vinifera L. in the French Mediterranean area. The results of the study indicate that the climate change might shorten
phenology cycle and cause an increase of the number of years with a quality worse than presently. - (BJ)
