Laguna di Venezia: gli effetti dell'impatto antropico sul degrado morfologico

The Venice Lagoon is a perhaps unique example of coevolution between humanity and the environment. Today, however, this extraordinary environment is undergoing severe morphological degradation, due to a series of factors, including the lack of sediment supply within the lagoon itself, a net loss of sediment to the Adriatic Sea, and intense erosion. In the final episode of the series dedicated to the Venice Lagoon, we explore with Andrea D'Alpaos, full professor at the Department of Geosciences at the University of Padua, the various human interventions that, over the centuries, have favored erosion processes. This reflection begins with past works such as the removal of rivers outside the lagoon, the construction of piers at the lagoon mouths, anthropogenic subsidence linked to the extraction of groundwater, and the excavation of large navigable canals, and continues today with the Mose system. It is necessary to protect Venice from the tides, but it can have significant impacts on the lagoon's environment, both morphologically and ecologically.
