Eroded Ecologies investigates the Venetian Lagoon as a contested ecological and cultural landscape shaped by centuries of infrastructural interventions, extractive practices, and constructed narratives of authenticity. Developed as a practice-based research project, the thesis combines fieldwork, installation, visual media, and critical writing to examine how engineering projects, agricultural policies, and tourism-driven imaginaries have progressively transformed both the material conditions and the symbolic identity of the lagoon. The research adopts the Purple Artichoke of Sant’Erasmo as a situated lens and quasi-object through which broader lagoonal processes are traced. Once a local and seasonal crop, the artichoke becomes a transmitter of layered histories: vernacular agricultural knowledge, colonial trade routes, infrastructural impositions such as the MOSE system, and contemporary regimes of branding and standardisation. By following this crop across fields, markets, and representations, the project exposes tensions between local ecologies and globalised discourses of resilience, sustainability, and heritage. Central to Eroded Ecologies is a critique of smooth ecological storytelling that obscures environmental erosion and uneven power relations. Drawing on thinkers such as Donna Haraway, Michel Serres, Anna Tsing, and Byung-Chul Han, the thesis proposes counter-narration as a method to foreground ambiguity, decay, and more-than-human agency. Rather than framing the lagoon as a fragile object to be preserved or engineered, the research reads it as a living palimpsest in which infrastructures, crops, sediments, and imaginaries co-produce space.
