Abstract
Rischi Naturali come Agenti di Cambiamento: Un'indagine sul Rapporto tra le Inondazioni e la Gestione dei Paesaggi Urbanizzati Abstract In the Anthropocene, the foundational assumption of stationarity the concept that natural systems fluctuate within an unchanging envelope of variability is "dead" (Milly et al., 2008), rendering traditional, history-driven hazard mapping obsolete for predicting climate-amplified "Black Swan" events. This research conducts a forensic reconstruction of the 2024 Chooralmala landslide in Wayanad, reclassifying it as a "Natech" (Natural-Technological) failure where anthropogenic triggers, specifically unscientific land use and resort construction, intersected with high-intensity precipitation to trigger catastrophic slope failure. Utilizing a "Visual and Verbal Forensic" methodology, the study triangulates post-disaster structural artifacts with situated tacit knowledge and geomorphological evidence.
Findings reveal a systemic maladaptation in state-sanctioned "hard" infrastructure; rigid reinforced concrete elements suffered catastrophic brittle failure under dynamic sediment pulses, whereas traditional "Safe-to-Fail" bio-engineering systems (Thayu) exhibited superior ecological resilience through energy absorption and soil cohesion
