ABSTRACT
Water represents a fundamental element for all sectors of economic, social and environmental interest. For the agricultural sector in particular, it plays a role as a key productive input for the conduction of related activities, both and especially in arid and semi-arid regions, but more and more often
in temperate ones. In the former, water allows to obtain a suffi cient crop production, in the latter to maintain production at high levels and reduce the risk of loss of the product (Tarimo et al. 1998; Iglesias et al. 2005; IPPC 2012).
