15. Sustainable Management of Hydraulic Resources in Sagua la Grande Basin (Villa Clara Province, Cuba), a Simulation Model with Systems Dynamics

The present article works on the relationship existing between the natural offer of the hydraulic resource and the social demand in the outlying area, including the Protected Area ‘Mogotes of Jumagua’, and the urban area of the basin Sagua la Grande, of the province Villa Clara. The areas have different necessities as for the use of the water, the outlying one eminently agricultural and the urban area for human and commercial consumption. For the analysis and interpretation, the tools of Systems Dynamics were used, generating the current model of the system, which allowed the understanding, in an integral way, of the problematic situation, and then to carry out the wanted changes, keeping in mind the infrastructure and the education. Firstly it proposed the improvement and maintenance of the reserves of water, the search of new reception sources, and maintenance of the net of ducts; secondly it proposed to carry out campaigns of environmental education to the users of the resource advocating for the best handling and efficient use of the water, as well as the reuse of disposed waters for agriculture.
