The TARGET Strategy shall establish a jointly developed and applicable method in the SUDOE space for: • One objective: the implementation of action plans for the sustainable management of water resources (SWRM) and the prevention of crisis situations linked to water scarcity through the integration of solutions for the use of non-conventional water resources (RANC). • Two scales of application: possible deployment at hydrographic scale, of the river basin, to identify and understand the problems by studying the suitability of the RANC, and at the local level of competition (water-sanitation, development, etc.), allowing the optimisation of the RANC. • Three principles to consider: improving the efficient use of water for all stakeholders; revalue non-conventional waters (reclaimed waters, rainwater, grey water, desalination, etc.); and put the necessary means through technical, economic and social innovation. • Four pillars to apply: consultation – state of play (current problems) – consultation – climate and socio-economic forecasting (future problems) – drawing up an action plan (actions/solutions to address problems). This method, as a toolbox of the GSRH, can be deployed differently depending on the territorial scale (local or basin) and the progress of the use of CRRs (opportunity, feasibility, improvement, etc.). It will propose solutions that have been tested through pilot actions (GT1) and demonstration actions (GT2). After analysing the transfer and replicability conditions (GT3), the TARGET Strategy will be adapted so that it can be applied throughout the SUDOE space, taking into account the different territorial levels. It will be adopted by at least 2 project partners (GRANOLLERS – Spain and EPIDOR – France) and at two territorial levels (local and river basin).
