Abstract
In the sphere of contemporary urban studies, the transition from the traditional paradigm of "vulnerability reduction" to the dynamic approach of "resilience" is recognized as a strategic necessity for managing the complexities and uncertainties of urban hazards. Physical resilience, as the tangible fabric of the city, plays a determining role in absorbing shocks, sustaining life, and accelerating recovery following a crisis. District 19 of Tehran, due to its composite and heterogeneous physical nature, the stressful coexistence of dilapidated residential settlements and industrial-workshop land uses, and its location on seismic zones, represents a prominent example of a "high-risk urban ecosystem" that requires a precise investigation of its resilience indicators. The present study was conducted with the aim of modeling and spatially assessing the components and indicators of physical resilience in this district. The research approach is descriptive-analytical and based on spatial analyses within the Geographic Information System (GIS) platform. In order to manage the inherent uncertainties of urban phenomena and avoid binary approaches, fuzzy logic was employed for standardizing and integrating information layers. The conceptual framework of the study was developed across five main dimensions: "structural and population vulnerability," "critical infrastructure and lifelines," "relief spaces and temporary settlement," "hazard intensifying centers," and "socio-economic supporting infrastructure." The analytical findings indicate the existence of profound spatial inequality and structural polarization across the district; such that the northern and central sectors (such as Khanabad Nov and Sharifi) enjoy a relatively favorable status due to resilient structures, optimal access to main arteries, and an appropriate density of vital services. In contrast, the southern and southwestern belt (including Ne’matabad and Ahmad Khomeini Town) are in a critical state and possess high vulnerability due to the synergy of factors such as severe physical deterioration, impermeability of passages, severe poverty in relief and medical infrastructure, and proximity to industrial hazard centers. The results demonstrate that enhancing resilience in District 19 necessitates a transition from general interventions to place-based strategies; such that in the north of the district, the focus is on density management and maintaining infrastructure efficiency, while in the southern half, priority is assigned to physical regeneration, fabric permeability, safety measures for incompatible land uses, and the equitable distribution of relief services.
