Climate Change Impacts on Typical Mediterranean Crops and Evaluation of Adaptation Strategies to Cope With

In this study the impacts on durum wheat and grapevine yields, and olive suitable cultivation area were investigated for two time slices under A1B SRES scenario, at first. Then, some adaptation strategies to cope with these impacts were explored. The results indicated that projected higher temperatures resulted in a general advance of phenological stages with respect to the baseline and in a shorter inter-phase time for both durum wheat and grapevine. Despite the general decrease of time for biomass accumulation, durum wheat took advantage of the positive effect of higher CO2 concentration, while grapevine resulted more vulnerable to warmer and drier future climate. Adaptation options, aiming at avoiding extremely high temperatures during sensible phases and prolonging the duration of the reproductive stage, resulted as positive strategies to alleviate negative impacts or exploit possible beneficial effects of a changing climate. Finally, the rising temperature will cause a northward and eastward shift of the olive tree suitable area.
