Coastal areas in cities of the Global South are increasingly exposed to climate uncertainty, adding to existing conditions of ecological degradation and high socio-spatial inequality.

Drawing on global debates on hybrid infrastructures, floodable urbanism, and regenerative waterfront strategies, the research translates these principles into a territorially grounded exploratory design proposal. The selected area of Callao, commonly known as Barracones, is identified as particularly vulnerable due to its socio-economic complexity and spatial challenges, including exposure to coastal surges and tsunamis, an inaccessible urban waterfront, abandoned industrial areas, and informal urban growth. The project proposes a framework of adaptive interventions that integrate grey and nature-based solutions for coastal defenses, community spaces for economic activation and a proposal to organize incremental urban growth. These armatures operate as open-ended frameworks, designed to adapt to environmental changes while also strengthening local capacities and recovering the relationship between the Barracones community and their coastal edge. By framing the coastline as a catalytic structural system instead of a neglected edge, the thesis contributes to current discussions on how coastal cities in the Global South can shift from vulnerability to resilience across spatial, ecological, and social dimensions.

Le zone costiere delle città del Sud globale sono sempre più esposte all'incertezza climatica, che si aggiunge alle condizioni già esistenti di degrado ecologico e forte disuguaglianza socio-spaziale. A Callao, città portuale della capitale del Perù, la zona costiera evidenzia la tensione tra la dipendenza economica dalle infrastrutture industriali, la fragilità degli ecosistemi litoranei e la crescita urbana informale. Questa tesi analizza le condizioni del litorale per ridefinire le aree sottoutilizzate e a rischio come un paesaggio strutturante che sostiene la resilienza ambientale e socioeconomica a lungo termine. La tesi utilizza una metodologia di ricerca-progettazione per sviluppare il concetto di armature adattive: strutture spaziali e infrastrutturali che organizzano il ripristino ecologico, lo sviluppo urbano incrementale e l'attivazione socioeconomica trasversale lungo la costa di Callao. Attingendo ai dibattiti globali sulle infrastrutture ibride, sull'urbanistica alluvionabile e sulle strategie di rigenerazione del litorale, la ricerca traduce questi principi in una proposta di progettazione esplorativa radicata nel territorio. L'area selezionata di Callao, comunemente nota come Barracones, è ritenuta particolarmente vulnerabile per la sua complessità socioeconomica e per sfide spaziali, tra cui l'esposizione alle mareggiate costiere e agli tsunami, un litorale urbano inaccessibile, aree industriali abbandonate e crescita urbana informale. Il progetto propone un quadro di interventi adattivi che integrano soluzioni grigie e basate sulla natura per la difesa costiera, spazi comunitari per l'attivazione economica e una proposta per organizzare una crescita urbana incrementale. Queste armature funzionano come strutture aperte, in grado di adattarsi all'ambiente, rafforzando al contempo le capacità locali e recuperando il rapporto tra la comunità di Barracones e il suo litorale. Inquadrando la costa come un sistema strutturale catalizzatore invece che come un confine trascurato, la tesi contribuisce alle attuali discussioni su come le città costiere del Sud del mondo possano passare dalla vulnerabilità alla resilienza in tutte le dimensioni spaziali, ecologiche e sociali. Offre spunti di riflessione per contesti simili che devono bilanciare le priorità socio-economiche con l'adattamento climatico, promuovendo uno sviluppo sostenibile complessivo.

Abstract
Coastal areas in cities of the Global South are increasingly exposed to climate uncertainty, adding to existing conditions of ecological degradation and high socio-spatial inequality. In Callao, Peru’s capital port city, the coastal zone highlights the tension between economic dependency on industrial infrastructures, fragile littoral ecosystems and informal urban growth. This thesis analyzes coastal edge conditions to reframe underutilized, at-risk areas as a structuring landscape that supports long-term environmental and socio-economic resilience. The thesis applies a research-by-design methodology to develop the concept of adaptive armatures: spatial and infrastructural frameworks that organize ecological restoration, incremental urban development and transversal socio-economic activation along the Callao coast. Drawing on global debates on hybrid infrastructures, floodable urbanism, and regenerative waterfront strategies, the research translates these principles into a territorially grounded exploratory design proposal. The selected area of Callao, commonly known as Barracones, is identified as particularly vulnerable due to its socio-economic complexity and spatial challenges, including exposure to coastal surges and tsunamis, an inaccessible urban waterfront, abandoned industrial areas, and informal urban growth. The project proposes a framework of adaptive interventions that integrate grey and nature-based solutions for coastal defenses, community spaces for economic activation and a proposal to organize incremental urban growth. These armatures operate as open-ended frameworks, designed to adapt to environmental changes while also strengthening local capacities and recovering the relationship between the Barracones community and their coastal edge. By framing the coastline as a catalytic structural system instead of a neglected edge, the thesis contributes to current discussions on how coastal cities in the Global South can shift from vulnerability to resilience across spatial, ecological, and social dimensions. It offers insights for similar contexts that must balance socio-economic priorities with climate adaptation, promoting overall sustainable development.| File | Dimensione | Formato | |
