Thesis Abstract

Abstract
Urban Heat Island (UHI) effect is a well-documented phenomenon that poses significant challenges to urban areas, impacting both the environment and the health and well-being of residents. Green infrastructure has emerged as a promising solution to mitigate the adverse effects of UHI, offering numerous benefits such as temperature reduction, improved air quality, and enhanced aesthetic value. This thesis aims to assess the impact of green infrastructure on UHI effect in a metropolitan area, focusing on understanding the effectiveness of various green infrastructure interventions in reducing urban heat and improving overall urban climate resilience. The study begins with an introduction to the research topic, providing a background of the study and highlighting the significance and relevance of investigating the relationship between green infrastructure and UHI effect in urban settings. The problem statement identifies the current challenges associated with UHI effect and the gaps in existing research that this study seeks to address. The objectives of the study are outlined to guide the research process, focusing on evaluating the effectiveness of different types of green infrastructure in mitigating UHI effect, assessing the key factors influencing the success of green infrastructure interventions, and providing recommendations for sustainable urban planning and development. Limitations of the study are acknowledged, including constraints related to data availability, time, and resources. The scope of the study is defined in terms of the geographical area of investigation, the types of green infrastructure interventions to be evaluated, and the specific metrics and indicators used to assess their impact on UHI effect. A comprehensive literature review is conducted to explore existing research on green infrastructure, urban heat island effect, and their interrelationships. Ten key themes are identified, including the benefits of green infrastructure, factors influencing UHI effect, best practices for green infrastructure design, and methodologies for evaluating the effectiveness of green infrastructure interventions. The research methodology section outlines the approach taken to collect and analyze data, including the selection of study sites, data collection methods, and analytical techniques used to assess the impact of green infrastructure on UHI effect. Eight key components are detailed, covering data collection protocols, site selection criteria, measurement techniques, and statistical analysis procedures. The findings of the study are presented and discussed in Chapter Four, highlighting the effectiveness of different green infrastructure interventions in reducing urban heat and improving microclimate conditions. The results are interpreted in the context of existing literature and urban planning practices, identifying key success factors and challenges in implementing green infrastructure solutions. In conclusion, the study synthesizes the key findings and implications for urban planning and policy-making, emphasizing the importance of integrating green infrastructure strategies into urban development plans to enhance climate resilience and create sustainable, livable urban environments. Recommendations for future research and practical applications of the study findings are provided to guide further exploration and implementation of green infrastructure solutions in metropolitan areas. This thesis contributes to the growing body of knowledge on green infrastructure and urban heat island effect, providing valuable insights for policymakers, urban planners, and researchers seeking to address the challenges of urbanization and climate change in metropolitan areas.

Thesis Overview

The research project titled "Assessing the Impact of Green Infrastructure on Urban Heat Island Effect in a Metropolitan Area" aims to investigate the effectiveness of green infrastructure in mitigating the Urban Heat Island (UHI) effect within a metropolitan area. Urban Heat Island is a well-documented phenomenon where urban areas experience significantly higher temperatures compared to their rural surroundings due to human activities and infrastructure. Green infrastructure, such as parks, green roofs, and urban forests, has been proposed as a sustainable solution to combat the UHI effect by providing cooling benefits and enhancing natural processes within urban environments. The study will begin with an introduction providing an overview of the UHI effect, its causes, and the role of green infrastructure in urban planning and design. The background of the study will delve into existing literature on UHI mitigation strategies, emphasizing the potential of green infrastructure in reducing urban temperatures and improving overall urban livability. The problem statement will highlight the pressing need to address the UHI effect in metropolitan areas, considering the adverse impacts on public health, energy consumption, and environmental quality. The objectives of the study will be outlined to investigate the specific impacts of different types of green infrastructure on reducing surface temperatures and enhancing thermal comfort in urban settings. The research methodology will involve a combination of field measurements, satellite imagery analysis, and computer simulations to assess the thermal performance of green infrastructure in mitigating the UHI effect. Various parameters, such as land surface temperature, vegetation cover, and building density, will be analyzed to evaluate the effectiveness of green infrastructure interventions. The discussion of findings will present the results of the study, including the temperature reductions achieved through green infrastructure implementation, the spatial distribution of cooling effects, and the economic and environmental benefits of UHI mitigation strategies. The implications of the findings for urban planning and policy-making will be discussed to promote the integration of green infrastructure into future development projects within metropolitan areas. In conclusion, this research project seeks to advance our understanding of the role of green infrastructure in addressing the Urban Heat Island effect and enhancing urban sustainability. By assessing the impact of green infrastructure on thermal comfort and environmental quality in a metropolitan area, this study aims to provide valuable insights for creating healthier and more resilient cities in the face of climate change and urbanization pressures.
