Sustainability is a feature that most companies adopt in order to improve their profits, even when their activity is not sustainable or the definition in their sector is not clear. This concept actually relates to the management of natural resources. Agriculture, and particularly irrigation scheduling, is strongly linked to a sustainable management; however, it is not clear what defines a sustainable management. Several efforts have been made to improve the conservation of water resources, but most of them have not involved growers at the orchard level; and consequently, they have lost their opportunity to create a real improvement in terms of sustainability. The aim of this work was to design a “hydroSOStainable index” (or “hydroSOS index”) that evaluates different aspects at orchard level to improve the sustainability of the water resources. The hydroSOS index considers 16 indicators grouped in 4 areas: (i) hydraulic indicators, (ii) horticultural indicators not related to irrigation scheduling, (iii) horticultural indicators related to the moment when deficit irrigation is applied (when?), and (iv) horticultural indicators related to the way deficit irrigation is applied (how?). Each indicator provides different marks or scores, and their sum allows classifying orchard management into four labels. The weight of each indicator and each group is not in itself enough to obtain a maximum label. Groups allow to easily identify the main limitations for the orchard to achieve a sustainable irrigation management. This index was used to evaluate water management of two cases of study.
