It will consist of an inclusive document including multilevel governance (local, regional, national and European). The strategy aims to improve the efficiency of water uses, as well as the sustainable management of water resources, contemplating regenerated water as an alternative water resource and that must be studied and mobilised for an efficient and inclusive management in the SUDOE space, focused on its use in the irrigation of crops. The development of a transnational, joint strategy will be obtained from an integrative vision (water resource modelling, life cycle analysis, and socio-economic analysis) with which an improvement of irrigation management is achieved, and therefore reducing the impact of crops on water resources, releasing the pressure on the drinking water system in global terms in the SUDOE space.
