Las políticas de trasvases de agua y desalación en España, sus repercusiones en la ordenación del territorio del sureste

Resumo

The territory of the Southeast of the Iberian Peninsula records a Mediterranean climate with features of aridity. The balance of resources ‐ water demands presents a structural deficit, which has been tried to reduce through external resources (transfers) and new own water resources (desalination). The route of the aqueducts in order to distribute different water flows, as well as the places where to locate facilities for desalination are essential elements in the territorial model of the Southeast of Spain, as the socioeconomic activity is developed around them. The hydraulic heritage has been enriched with water elevations (impulsion and pumping), aqueducts (canals, siphons, pipes), areas of water accumulation (ponds, reservoirs, tanks), water treatment plants, hydroelectric plants, etc. In recent years, both offer of resources policies (transfers, desalination) and demand management (modernization of irrigation, improvement of management of supply companies, etc.) have been aimed at achieving water security for irrigators and citizens.
