0.5 is an audiovisual installation that presents the contrasting roles of technological and collective intelligence in preserving the Venetian lagoon. The project brings together the analytical world of various academic centres for climatological research in Venice and the intergenerational knowledge of the fishing community in the north of the territory, critically examining the lagoon’s inherently fragile and oscillating ecosystem. Conceived as a dialogue between these two seemingly oppositional practices, 0.5 is structured around four key themes, each weaving together data visualisation and narrative storytelling to underscore the critical relationship between the natural and artificial forms of intelligence unfolding across the lagoon.
