International audienceOlive growers in Andalusia are concerned about the impact of climate change on their activity, which is very important in terms of surface area, production and income. In an attempt to answer these questions, this work first describes the evolution of climate and annual yields of rainfed and irrigated olive groves in the province of Jaén (Andalusia) since the 1950s. Second, the relationships between rainfed and irrigated yields on one side and climatic variables on the other side are modelled. Finally, the models allow the calculation and mapping of the current theoretical spatial distribution of yields. Yields vary greatly from year to year, but are generally higher in irrigated than in rainfed orchards. Yields have r...
