“Mia nonna indovinò in fretta i mutamenti radicali che si affacciavano”. L’infrastrutturazione idroelettrica dell’Alta Valtellina in una prospettiva storico-ambientale (1906–1968)

The article aims to provide a series of analytical points regarding the transformations occurring to the environment and countryside in the Upper Valtellina resulting from the arrival of the first forms of hydroelectric production at the start of the twentieth century and the massive development it underwent, up until the end of the 1960s. In particular, the article undertakes a descriptive analysis of the various phases of unabridged hydroelectric exploitation that have affected this area. It looks closely at the documentary sources and also presents the first results from a series of investigations being carried out within an ongoing interdisciplinary and multidisciplinary research project. Finally, drawing on the stimulus provided by the discussion in recent years at the international level within the Environmental Humanities, the article also undertakes an analytical examination of the interdependent relationship that has emerged between the city of Milan and a remote region located in the centre of the Alps
