The relative yield decline that is expected under specific levels of water stress at different moments in the growing period is estimated by integrating the FAO Ky approach in the soil water balance model BUDGET. FAO recently developed a water-driven model (Aqua-Crop) for use as a decision support tool in planning and scenario analysis in different seasons and locations. The Aqua Crop model was evaluated with experimental data collected during three cropping seasons; the field experiments were conducted in Setif, Algeria. The objective of the study is to quantify the water stress based on estimationof evapo-transpiration by Aqua Crop model in Durum wheat under stressed conditions. The results of this study proved the efficiency of the Aqua Crop model to quantify the water stress. Total water stress during three cropping seasons (2010–2013) ranged between 0.15 (15%) at Double ridges to anthesis stage to 0.56 (56%) at Anthesis to maturity stage. The Aqua Crop model can adequately quantify water stress and can be used to explore management options to improve
