Water Resources Issues in CastillaLa Mancha

2.1 General Characteristics

2.1.1 Edafoclimatic Conditions and Water Resources

Due to CLM being situated in the center of the Iberian Peninsula the sources of important rivers are located within this region, such as the Tajo and Guadiana, of the Atlantic side, the Jucar and the Segura of the Mediterranean, as well as, some tributaries of the Duero, Ebro and Guadalquivir (CES, 2006). Since not one of the aforementioned rivers is completely included within the territory of CLM, this denotes that hydrological planning is a national government competency. Therefore, administratively CLM belongs to 7 hydrographic authorities (Figure 1).

In Spain, all of the hydrographic river basins that are shared by two or more regions are managed by the Environmental Ministry through the Hydrographic Confederations. Only the intra-communitarian river basins can be managed directly by the regions, although they can cede its management to a national government agency. The Hydrographic Confederations are in charge of the elaboration of the Hydrological Plans of the river basin. These documents collect, among other information, what the volume of water generated inside the river basin is, and what the demands and the quantity of dedicated resources to cover such demands will be. The last Hydrological Plans were elaborated in 1998 and will be updated in 2008.
