The thesis hereby presented constitutes an innovative synthesis of real estate management, public administration, and stakeholder management, aimed at redefining the concept of the public-private-people partnership (4P) within urban regeneration contexts by introducing the community land trust (CLT) form of landownership. The substantially diverse stakeholders that this innovative partnership scheme seeks to engage necessitate consideration beyond mere architectural, engineering, and urban planning perspectives.

Therefore, it is essential to understand the full scope of urban regeneration projects comprehensively and to enrich the existing literature on the 4Ps to date. To this end, a knowledge-building survey was conducted with the objective of further enhancing the existing 4P framework, based on insights provided by experienced professionals within the real estate investment sector and public administration. A hypothetical transition from a conventional public-private partnership (3P) to a 4P was proposed. Similarly, the viability of establishing community land trusts across diverse contexts has been validated through an analysis of legal frameworks and four case studies.

La presente tesi propone una sintesi innovativa tra gestione immobiliare, pubblica amministrazione e gestione degli stakeholder, con l'obiettivo di ridefinire il concetto di public-private-people partnership (4P) nell'ambito della rigenerazione urbana attraverso l'introduzione del modello di proprietà noto come 'community land trust' (CLT). La diversità degli attori coinvolti in questo modello innovativo di partenariato richiede un approccio che vada oltre le prospettive puramente architettoniche, ingegneristiche e urbanistiche, tenendo conto anche di realtà ed esperienze culturali, economiche e sociologiche più ampie. Tale ridefinizione concettuale introduce un nuovo modello di partenariato adattabile a diversi contesti. Risulta quindi fondamentale comprendere appieno la portata dei progetti di rigenerazione urbana e arricchire la letteratura esistente sui modelli 4P. A tal fine, è stata condotta un'indagine conoscitiva volta a potenziare l'attuale quadro di riferimento dei 4P, basandosi sui contributi di professionisti esperti del settore degli investimenti immobiliari e della pubblica amministrazione. È stata ipotizzata una transizione dal tradizionale partenariato pubblico-privato (3P) al modello 4P. Parallelamente, è stata verificata la fattibilità dell'istituzione di community land trust in contesti diversi attraverso l'analisi dei quadri normativi e di quattro casi studio. Un gruppo di esperti ha valutato il modello basato sull'integrazione tra 4P e CLT mediante un processo di tipo Delphi articolato in due fasi. Il modello finale, presentato nel sesto capitolo della tesi, segna un cambio di paradigma che coinvolge due concetti i quali, secondo la letteratura esistente, non si sono storicamente mai intersecati. L'innovazione introdotta dalla ricerca risiede proprio nell'integrazione di tali concetti e nella loro evoluzione da misure passive a strumenti proattivi di [ri]urbanizzazione.

Abstract
The thesis hereby presented constitutes an innovative synthesis of real estate management, public administration, and stakeholder management, aimed at redefining the concept of the public-private-people partnership (4P) within urban regeneration contexts by introducing the community land trust (CLT) form of landownership. The substantially diverse stakeholders that this innovative partnership scheme seeks to engage necessitate consideration beyond mere architectural, engineering, and urban planning perspectives. It is crucial to also account for broader cultural, economic, and sociological realities and experiences. Such a conceptual redefinition introduces a novel partnership model adaptable across various contexts. Therefore, it is essential to understand the full scope of urban regeneration projects comprehensively and to enrich the existing literature on the 4Ps to date. To this end, a knowledge-building survey was conducted with the objective of further enhancing the existing 4P framework, based on insights provided by experienced professionals within the real estate investment sector and public administration. A hypothetical transition from a conventional public-private partnership (3P) to a 4P was proposed. Similarly, the viability of establishing community land trusts across diverse contexts has been validated through an analysis of legal frameworks and four case studies. A panel of expert professionals has evaluated a 4P/CLT-based framework through a two-round Delphi-like process. The final model, as presented in chapter 6 of this thesis, signifies a paradigm shift involving two concepts that, according to existing literature, have historically not intersected. The innovation introduced by this research is precisely the integration of these two concepts and their transition from passive measures to proactive instruments of [re]urbanization.| File | Dimensione | Formato | |
