“…Among them, we can find some management measures devoted to the water supply, such as the joint use of surface and groundwater [ 10 , 13 , 17 , 21 ], water transfers [ 22 , 23 , 24 ], the introduction of alternative water resources (desalinated or re-used water) [ 14 , 25 , 26 , 27 , 28 ], as well as the development of efficient rainwater collectors [ 29 , 30 , 31 ]. Regarding the demand side, the following proposals have been given: the limitation of groundwater extraction according to the natural water recharge level [ 15 , 32 , 33 , 34 , 35 ]; restrictions to irrigation and to new extractions [ 21 , 30 , 36 ]; rearrangements of water extraction points [ 18 , 37 , 38 , 39 , 40 ]; the establishment of charging systems in order to discourage well water consumption [ 19 , 41 , 42 ]; and efficiency improvements in water management [ 16 , 36 , 43 , 44 ].…”
