Assessing the Impact of Urban Heat Islands on Local Climate Variability and Human Well-being in [City/Region]: A Geospatial and Temporal Analysis using Remote Sensing and GIS (Final Year Project Topic)

Project Abstract

Urban Heat Islands (UHIs) are increasingly shaping local climate regimes and affecting human well-being in rapidly expanding cities, where dense built form, material properties, limited vegetation, and anthropogenic heat release converge to produce measurable temperature elevations relative to surrounding rural areas. This study adopts a geospatial and temporal analytical framework to quantify UHI intensity across [City/Region], examine its drivers, and evaluate the cascading impacts on climate variability, health outcomes, energy demand, and socio-economic vulnerability. By integrating multitemporal Landsat and sentinel-2 derived land surface temperatures, normalized difference vegetation index (NDVI), albedo, impervious surface fraction, and near-surface air temperature data from local meteorological stations, the research constructs high-resolution UHI maps for distinct seasons and urban growth phases over the past two decades. Geographically Weighted Regression (GWR) and machine learning approaches are employed to disentangle the relative contributions of land cover, urban morphology, material properties, and green infrastructure to observed temperature patterns, while robust uncertainty analyses address data gaps and sensor biases. The study further links UHI intensity to local climate variability indicators, including diurnal temperature range, heat index, and nighttime cooling rates, and analyzes temporal trends to identify persistent hotspots and transient anomalies associated with meteorological extremes and urban development cycles. A health and well-being dimension is integrated by correlating UHI metrics with ambulance call data, hospital admissions for heat-related illnesses, self-reported discomfort indices, and energy consumption patterns, controlling for age, income, and housing quality to uncover exposure disparities among vulnerable groups. An energy demand model estimates the incremental cooling load and associated greenhouse gas emissions, informing cost–benefit considerations for mitigation interventions. The research assesses adaptation pathways, contrasting green infrastructure, cool roofs, reflective pavements, and urban design strategies in terms of effectiveness, feasibility, and equity. Policy-relevant findings highlight the spatial prioritization of cooling interventions in densely populated neighborhoods with high vulnerability and limited green space, as well as the importance of integrating UHIs into urban planning, public health surveillance, and climate resilience programming. Data fusion techniques are demonstrated to harmonize heterogeneous datasets across scales, while participatory mapping and stakeholder interviews provide local context and validate model outputs. The anticipated contributions include (i) a replicable methodological workflow for UHI assessment in medium to large urban regions using freely available remote sensing and GIS data, (ii) a nuanced understanding of how UHIs modulate local climate variability and health outcomes, and (iii) actionable recommendations for targeted, equitable mitigation and adaptation strategies. This work advances the capacity of urban climatology to inform evidence-based decision-making, supports proactive public health planning during extreme heat events, and offers a scalable template for similar cities undergoing rapid urban transformation.

Project Overview

What This Project Is About

---

The project looks at how urban areas become hotter than surrounding regions and how this heat affects local weather patterns and people’s daily lives. It uses simple maps and data from satellites and local sensors to see where heat is worst and why it matters for health, comfort, and energy use.

The Problem It Addresses

---

Cities often trap heat, creating urban heat islands that shift local climate and can worsen heat-related health issues. There is a gap in easily understandable, location-specific evidence showing how heat changes over time and affects residents. This project aims to fill that gap with clear, regional insights.

2. Explain the link between heat, air quality, and energy use.
3. Assess how heat impacts daily activities and well-being for residents.
4. Show simple maps and indicators that policymakers can use.
