Interazioni metropolitane

It’s a hard task to present this research by Giovanni Battista Cocco and Adriano Dessì without mentioning what has happened recently due to the pandemic. If we were to proceed on our reflection without considering the spread of the SARS-Cov-2 virus and Covid-19 infection, we would transmit a distorted image of our present and maybe we could only partially appreciate the work of the two researchers, who highlighted the significant features of a specific metropolitan condition and its potentials by using the architectural project as an investigative tool. Why talk about the pandemic if the volume was concluded just before the disaster began to spread? Because the consequences of the virus have, in general, put mankind’s ways of living on this earth in a difficult position and, in particular, the modus vivendi of large urban concentrations where the contradictions accumulated for decades have emerged with an even greater clarity. Therefore, talking about a metropolitan area - that of Cagliari observed from Sestu - becomes an important opportunity to understand the distance between the limits of the legislation erga omnes of the Italian metropolitan areas and the specificity of a context which is hardly comparable to others and therefore incomprehensible through a priori models. What is the challenge of the two re- searchers? Demonstrating, by discussing the case of Sestu, that there are alternatives to a mono-gravitational metropolitan system in which a single star radiates a set of satellites.
