  abstract = {{I}n the current context of climate change, the impact of trees in agroforestry systems is expected to mitigate water and heat stresses, particularly in semi-arid environments. {W}ithin this framework, in a two-year trial conducted at {INRAE} in {S}outhern {F}rance, the dynamics of microclimatic parameters and the edaphic environment of durum wheat were investigated under a yearly-pruned ({AF}) and a never-pruned ({AF}+) 6-m apart alley olive orchard, in comparison with controls under full sun. {H}ere it was recorded a reduction of photosynthetic active radiation ({PAR}) by 30% and 51% in {AF} and {AF}+, respectively, during the wheat cycle, together with a marked reduction of wind speed compared to controls (-85% in {AF} and -99% in {AF}+). {A} significant buffer effect was also highlighted for air temperature, averagely +1.7 degrees {C} during the night and -3.2 degrees {C} during the daytime under the moderate shading of {AF}. {T}he positive effect of trees on soil water conservation increased with the intensity of shading, particularly during the critical wheat stage of grain filling, with benefits on wheat root mycorrhization, and {NH}4+ and {NO}3- abundance in the arable layer. {D}espite some of the environmental modifications being favorable for the understorey wheat, these were not translated into yield improvements, suggesting that the severe shading associated with the small inter-row and evergreen trees has a prevailing effect, that requires to be managed through appropriate tree pruning.},
