Groundwater overexploitation of the carbonate aquifers in the Altiplano area (Murcia province, SE
Spain) represents an extreme situation of hydrologic deficit in a semiarid region supplied uniquely by
groundwater. The study of the water balance terms in a series of such aquifers is the hydrological key point
of an overall research aimed to make an integrated analysis of groundwater management. Estimation of
input and outputs is here made by the recharge and abstraction quantification respectively. On the other
hand, the knowledge of the hydrogeological behaviour of the aquifers- and therefore of their piezometric
evolutions- is closely linked to the evaluation of the volume of reserves, an aspect which is usually less
studied. Finally, a multidisciplinary analysis of the impacts generated by this type of groundwater
development is necessary in order to reach an agreement among the stakeholders with the highest degree
of consensus
