“…Finally, in the controversy on the effects of improving and modernizing of irrigable areas for water conservation, it is necessary to emphasize that there is an agreement on the environmental improvements derived from the improvement of irrigation infrastructures (Ortega et al, 2002;Causapé et al, 2004Causapé et al, , 2006Clemmens et al, 2008;Lecina et al, 2009), particularly when these actions are linked to overall improvements in the water use area (including management, irrigation scheduling, availability of irrigation advisory services, among others) .…”

The increasing demand of water for different uses, together with the variable availability of this resource, which is due to the increasingly frequent periods of drought, make necessary to undertake a set of structural and contextual actions to cope with the permanent or temporary scarcity situations. Within the search for solutions to the progressively more widespread situation of limited water availability for agriculture, this paper aims to state the role that engineering can play to face up this deficit, taking into account the social, economic, and environmental issues of water, together with the priority of uses. Structural measures can help to:1) increase the water availability (increased or more flexible supply through reservoirs, water transfers, water rights interchange centres, desalination, reuse, aquifer recovery, and conjunctive use of surface water and groundwater), and 2) rationalize water consumption by improving demand management, including the irrigation management improvement, as well as maximizing the efficiency of irrigation systems. In addition to these measures, other social issues can be implemented through public awareness and education, adequate economic policies, legislative adaptation, and technical support to municipalities and water use associations. Thus, to face up water scarcity in a region it is necessary to identify the different water sources, including alternative sources such as desalination and reuse, and develop an appropriate model of management as well as infrastructure for water storage and regulation.Additional key words: desalination; drought; irrigation; wastewater reuse; water management; water scarcity; water transfers. ResumenRevisión. El déficit hídrico y la ingeniería del agua La creciente demanda de agua para los distintos usos, junto con la variabilidad en la disponibilidad de este recurso debido a los cada vez más frecuentes periodos de sequía, hacen necesario llevar a cabo un conjunto de acciones estructurales y coyunturales para poder hacer frente a las situaciones de escasez temporal o permanente que se producen. Dentro de la búsqueda de soluciones a la situación cada vez más generalizada de limitada disponibilidad de agua para la agricultura, el presente trabajo pretende incidir en el papel que puede jugar la ingeniería a la hora de hacer frente a esta situación de déficit, teniendo en cuenta los aspectos sociales, económicos y ambientales del agua y sus prioridades de uso. Las medidas estructurales pueden contribuir a: 1) aumentar los recursos (aumento o flexibilidad de la oferta mediante embalses, trasvases, centros de intercambio de derechos de agua, desalinización, reutilización, recarga de acuíferos, o el uso conjunto de aguas superficiales y subterráneas), o 2) racionalizar los consumos (mejorando la gestión de la demanda, incluyendo la mejora de la gestión del regadío y la mejora de la eficiencia del riego en parcela). Además de estas medidas puede llevarse a cabo otras de carácter social como la concienciación y educación ciudadana, el fo...
