This thesis investigates the relationship between water, risk, and landscape in the age of the Anthropocene, with particular attention to the effects that climate change and contemporary urbanization have on urban and territorial systems. The intensification of extreme weather events, soil sealing, and the progressive artificialization of watercourses have increased the hydraulic vulnerability of cities, highlighting the limitations of traditional water management models based on rapid drainage systems and grey infrastructures. Within this context, the research explores the Sponge City paradigm as an innovative approach to integrated stormwater management and as a potential strategy for climate adaptation. This model proposes considering water not as an element to be rapidly removed, but as a resource to be retained, infiltrated, slowed down, and reused through multifunctional and distributed devices such as blue-green infrastructures, permeable surfaces, retention systems, and open spaces designed as hydrological devices. The aim of the thesis is twofold: on the one hand, to develop a theoretical and methodological framework connecting the Anthropocene, climate change, and transformations of the urban landscape; on the other hand, to evaluate the applicability of the Sponge City paradigm within the Italian context through the case study of the Leogra stream in the Upper Vicenza area. The Leogra represents a significant context for analyzing the critical issues related to territorial artificialization, ecological fragmentation, and increasing exposure to hydraulic risk. The adopted methodology combines theoretical analysis, the study of international case studies, and a landscape-based interpretation of the water–soil system, leading to the development of multiscalar design scenarios inspired by the principles of hydraulic invariance and Nature-Based Solutions. The research demonstrates how the Sponge City paradigm can contribute not only to the mitigation of hydrogeological risk, but also to the improvement of the ecological, climatic, and social quality of urban territories. The thesis concludes by proposing a landscape-oriented reinterpretation of the Sponge City paradigm, emphasizing the role of landscape design as a mediating tool between natural processes and anthropogenic transformations. From this perspective, landscape is understood as a resilient infrastructure capable of reconnecting human settlements, water, and soil, offering new adaptation strategies for contemporary cities.
La presente tesi analizza il rapporto tra acqua, rischio e paesaggio nell’epoca dell’Antropocene, con particolare attenzione agli effetti che il cambiamento climatico e l’urbanizzazione contemporanea producono sui sistemi urbani e territoriali. L’intensificazione degli eventi meteorologici estremi, l’impermeabilizzazione del suolo e la progressiva artificializzazione dei corsi d’acqua hanno infatti aumentato la vulnerabilità idraulica delle città, evidenziando i limiti dei modelli tradizionali di gestione delle acque basati sul drenaggio rapido e sulle infrastrutture grigie. In questo contesto, la ricerca approfondisce il paradigma della Sponge City (città spugna) come approccio innovativo alla gestione integrata delle acque meteoriche e come possibile strumento di adattamento climatico. Il modello propone di considerare l’acqua non come elemento da allontanare rapidamente, ma come risorsa da trattenere, infiltrare, rallentare e riutilizzare attraverso dispositivi diffusi e multifunzionali, quali infrastrutture blu-verdi, superfici permeabili, sistemi di ritenzione e spazi aperti progettati come dispositivi idrologici. L’obiettivo della tesi è duplice: da un lato costruire un quadro teorico e metodologico che metta in relazione Antropocene, cambiamento climatico e trasformazioni del paesaggio urbano; dall’altro verificare l’applicabilità del paradigma della città spugna nel contesto italiano attraverso il caso studio del torrente Leogra, nell’Alto Vicentino. Il Leogra rappresenta un contesto significativo per analizzare le criticità derivanti dall’artificializzazione del territorio, dalla frammentazione ecologica e dalla crescente esposizione al rischio idraulico. La metodologia adottata integra analisi teorica, studio di casi internazionali e lettura paesaggistica del sistema acqua–suolo, con l’elaborazione di scenari progettuali multiscalari orientati ai principi dell’invarianza idraulica e delle Nature-Based Solutions. La ricerca evidenzia come il paradigma della città spugna possa contribuire non solo alla mitigazione del rischio idrogeologico, ma anche al miglioramento della qualità ecologica, climatica e sociale dei territori urbani. La tesi conclude proponendo una reinterpretazione della città spugna in chiave paesaggistica, evidenziando il ruolo del progetto di paesaggio come strumento di mediazione tra processi naturali e trasformazioni antropiche. In questa prospettiva, il paesaggio viene inteso come infrastruttura resiliente capace di ricomporre il rapporto tra insediamento umano, acqua e suolo, offrendo nuove strategie di adattamento per le città contemporanee.
