Analysis of urban heat islands in a rapidly growing city using remote sensing techniques

Thesis Abstract

Abstract
Urban heat islands (UHIs) have become a significant environmental concern in rapidly growing cities around the world due to their detrimental impacts on human health, energy consumption, and overall urban climate. Remote sensing techniques offer a valuable tool for studying UHIs and understanding their spatial distribution and temporal dynamics. This thesis presents a comprehensive analysis of UHIs in a rapidly growing city using remote sensing methods to investigate the factors contributing to their formation and potential mitigation strategies. The study begins with an introduction to urban heat islands and their importance in urban climate research, followed by a detailed background of the study area and the problem statement highlighting the need to address UHIs in the context of rapid urbanization. The objectives of the study are outlined to investigate the spatial extent, intensity, and drivers of UHIs, along with assessing the effectiveness of remote sensing in monitoring and analyzing UHIs. The limitations and scope of the study are identified to provide a clear understanding of the research boundaries and potential implications. A thorough literature review is conducted in Chapter Two, covering ten key aspects related to UHIs, remote sensing techniques, urbanization trends, climate change impacts, and mitigation strategies. This review sets the theoretical framework for the study and contextualizes the research within existing knowledge and gaps in the field. Chapter Three details the research methodology, including data collection, processing, and analysis techniques utilized to study UHIs in the selected city. Eight components are discussed, such as satellite imagery acquisition, land surface temperature extraction, land use classification, and statistical modeling to quantify UHI effects and relationships with urban features. Chapter Four presents a comprehensive discussion of the findings obtained from the analysis of UHIs in the rapidly growing city. The results highlight the spatial distribution and intensity of UHIs, the influence of urban morphology and land cover on UHI formation, and the potential implications for urban planning and climate resilience. The findings are critically examined in relation to existing literature and implications for future research and policy interventions. In conclusion, Chapter Five summarizes the key findings of the study and presents implications for urban planning, climate adaptation, and sustainable development in rapidly growing cities facing UHI challenges. Recommendations for future research directions and practical strategies to mitigate UHIs are provided to enhance urban resilience and improve the quality of life for city residents. Overall, this thesis contributes to the understanding of UHIs in rapidly growing cities and highlights the importance of remote sensing techniques in monitoring and addressing urban climate challenges.
