Thesis Abstract

Abstract
Urban heat island (UHI) effect is a significant environmental challenge faced by city centers worldwide, leading to increased energy consumption, air pollution, and heat-related health issues. Green infrastructure has emerged as a promising solution to mitigate the UHI effect by enhancing urban vegetation cover and promoting natural cooling processes. This thesis investigates the impact of green infrastructure on reducing the UHI effect in city centers through a comprehensive assessment framework. The study begins with a detailed introduction to the UHI effect, highlighting its causes and consequences in urban environments. The background of the study provides a contextual understanding of the importance of green infrastructure in urban planning and its potential to combat the UHI effect. The problem statement identifies the gap in existing research regarding the specific impact of green infrastructure on UHI reduction in city centers. The objectives of the study include assessing the effectiveness of different types of green infrastructure in lowering ambient temperatures and improving microclimate conditions in city centers. The limitations of the study are acknowledged, such as data availability and the complexity of urban systems. The scope of the study focuses on selected city centers known for their UHI intensity, with a detailed analysis of green infrastructure interventions. The significance of the study lies in providing evidence-based recommendations for urban planners and policymakers to integrate green infrastructure as a sustainable solution for UHI mitigation. The structure of the thesis outlines the organization of chapters and key sections, guiding the reader through the research process. Definitions of key terms related to urban heat island, green infrastructure, and city centers are provided for clarity. The literature review synthesizes existing research on green infrastructure and its impact on UHI reduction, presenting ten key findings from relevant studies. The research methodology section outlines the approach taken in data collection, analysis, and modeling, including eight detailed components such as site selection, data sources, and statistical methods. The discussion of findings delves into the results of the study, comparing the effectiveness of different green infrastructure interventions in reducing urban heat island intensity. The analysis considers factors such as vegetation type, spatial distribution, and maintenance practices in influencing the cooling effect of green infrastructure. In conclusion, the study emphasizes the importance of green infrastructure as a sustainable urban planning strategy to mitigate the urban heat island effect in city centers. The summary highlights the key findings, implications for practice, and recommendations for future research in advancing green infrastructure solutions for climate-resilient cities. Overall, this thesis contributes to the growing body of knowledge on sustainable urban development and environmental management in the face of climate change challenges.
