Proposta di strategie di gestione sostenibile della risorsa idrica, in ambiente mediterraneo, finalizzata agli interventi per la lotta alla desertificazione (Sardinia NW, Italy)

This paper is concerned with the methodological approach and preliminary results of a study
conducted on the sustainable management of water resources aimed ultimately at defining measures
for combating desertification. The primary object is to explore and develop models and strategies for
innovative and sustainable water resources management solutions, adopting a multidisciplinary
approach, at the drainage and/or hydrogeological basin scale in a Mediterranean context, using a
case study from a pilot area in Sardinia as a basis. Criteria for selecting the pilot area were dictated by
the need for specific features such as the presence of surface waterbodies (rivers, channels, dams,
etc.), of confined and unconfined aquifers and of urban agglomerates and productive activities, thus
with competing water demands. An area was identified in the NW part of Sardinia, in the Nurra region,
specifically the basin draining into the Calich lagoon. A multidisciplinary research project has been
drawn up and tested for the purpose of collecting the necessary information required for developing
integrated and sustainable water resource management solutions, also taking into consideration
recently enforced legislation.
