Water supply from marine source and governance modelling for integrating alternative technologies and the coastal territory in harmony with landscape constraints

The growing need for fresh water suitable for drinking and for rural and industrial applications is a bottleneck point for the development of many countries where the availability is scarce due to the adverse climate and environmental conditions. However there is a need for fresh water also in industrialized countries where critical mismatches between availability and requirements appear periodically. Where access to marine coasts is given a valuable solution could be the sea water desalination. An example of the water scarcity problems encountered in the tourist season and of the perspectives offered by a desalination plant is considered to show a methodology. The availability of significant renewable resources leads to exploit them just to feed the desalination plant in order to obtain a sustainable enhancement of the water system of the site. Due to the intermittent character of the sources as well as of the users demand various solutions are to be considered taking into account the environmental issues. The size of the plant is determined after evaluating the trends of the renewable energy supply and of the water demand
