Requisiti ambientali per il progetto della città lagunare nella Sardegna Centro Occidentale

The assumption of the thesis is that the city and the territory be considered two inseparable realities. Placing ecological issues and city design side by side can have an important influence in developing planning forms that will take into account the physiology of the region, and pay significant attention to the dynamic aspects and ecological processes underway there. Starting with the debate on low-density settlement situations and referring in particular to lagoon areas as ecologically complex environmental and settlement spaces, the thesis focuses on the city in terms of a territorial space interpreted as an intricate autotrophic and heterotrophic ecosystem in continuous evolution. Attention is explicitly focused on some critical environmental spheres, namely the lagoon areas, urban systems that are sensitive to the changes occurring in the environment due to human activities carried out on a hydrographic basin scale. The context examined is the Oristano region in west-central Sardinia, especially the territorial areas of the Cabras and Santa Giusta lagoons, where one of the important issues is the management of the integrated water cycle, linked with agricultural and fishing problems, but above all with the future of the small urban realities and the quality of the spaces they own for fruition of the environment.
