Assessing Urban Resilience to Heat: A City Council Case Study

Thesis Abstract

Urban areas increasingly confront heat-related stress driven by climate change, urbanization, and land-use patterns, which collectively threaten public health, energy systems, and social equity. This study addresses the problem of insufficiently understood municipal-level heat resilience, by examining how a mid-sized metropolitan city council can integrate climate adaptation, urban design, and social protection to reduce heat exposure and vulnerability. The aim is to evaluate current resilience capacities and to propose an actionable framework for enhancing adaptive governance under rising temperatures. Specific objectives are (1) to quantify urban heat exposure patterns and differential vulnerability across neighbourhoods using high-resolution land-surface temperature data and demographic indicators; (2) to assess the effectiveness of existing cooling strategies, emergency response protocols, and green infrastructure programs through policy audits and stakeholder surveys; (3) to identify governance, institutional, and infrastructural constraints to resilience, and (4) to develop an integrated heat resilience model combining physical, social, and governance dimensions to inform city-level decision-making. The research adopts a mixed-methods design anchored in the socio-ecological resilience and adaptive governance literatures, drawing on the theoretical foundations of the Social-E-Systems resilience framework and the Multi-Level Perspective on urban sustainability. Empirically, the study combines quantitative analyses of thermal exposure and vulnerability with qualitative insights from policy actors. The population comprises staff and elected officials within the City Council, municipal departments (environment, health, urban planning, energy), and community organizations located in the city. A stratified random sample of 120 council staff and department representatives is employed, along with 30 in-depth interviews with urban planners, climate program managers, and NGO partners. Data collection instruments include (i) GIS-based analyses of thermal maps using Landsat 8 and Sentinel-2 imagery for 2020–2025; (ii) a structured policy audit checklist evaluating cooling programs, zoning codes, and green-space targets; (iii) a standardized survey instrument capturing perceptions of resilience, preparedness, and social equity across 400 residents sampled to reflect socio-economic and demographic diversity; and (iv) semi-structured interviews and focus groups with key informants. Instrument validity is established through expert panel review and pilot testing, with reliability confirmed by Cronbach’s alpha (>0.80) for survey scales. Data analysis proceeds in three integrated streams. Quantitative data are analyzed using regression models to identify determinants of heat vulnerability, spatial econometric techniques to detect clustering of risk, and time-series analysis to examine trends in ambient temperature and cooling demand. The qualitative data are analyzed using thematic analysis guided by the framework method, enabling cross-case synthesis of governance bottlenecks and adaptation practices. A convergent mixed-methods approach is applied to integrate findings, with a compositional model constructed to link physical exposure, social vulnerability, and governance capacity. Ethical considerations include informed consent, data anonymization, and protection of vulnerable populations, with study approval obtained from the university ethics review board. Expected findings indicate spatial disparities in heat exposure and vulnerability, uneven distribution of cooling resources, and gaps in interdepartmental coordination and community engagement. The integrated heat resilience model is anticipated to reveal that governance adaptability, procedural flexibility, and inclusive co-management with community organizations significantly mediate the translation of physical infrastructure investments into effective resilience outcomes. Contributions to knowledge include (i) a transferable municipal heat resilience framework that explicitly integrates physical, social, and governance dimensions; (ii) empirical evidence on the relative effectiveness of cooling strategies and urban design interventions within a city council context; and (iii) methodological advances in combining high-resolution thermal analytics with policy-process evaluations. The study informs practitioners and policymakers about prioritization of investments in green infrastructure, heat-health early-warning systems, and participatory planning processes, while highlighting equity considerations for vulnerable groups. The conclusion emphasizes that resilient urban systems emerge from coordinated governance, targeted infrastructural investments, and community-based adaptation, rather than from singular technological fixes. Recommendations include strengthening cross-departmental heat governance, expanding community co-management of cooling spaces, scaling up green corridors and reflective pavements, standardizing heat-risk communication, and institutionalizing iterative monitoring and learning cycles to adapt policies to evolving climatic conditions.
