Urban areas face significant challenges related to air quality degradation, posing serious health risks to residents. Urban green spaces have been identified as potential solutions for improving air quality by mitigating pollution levels through various mechanisms. This study aims to assess the impact of urban green spaces on air quality in a metropolitan area, focusing on understanding the relationship between green spaces and air quality parameters. The research methodology involves a combination of field measurements, data analysis, and statistical modeling to evaluate the influence of green spaces on air quality indicators. The introduction provides a background to the study, highlighting the importance of addressing air quality issues in urban environments and the potential role of green spaces in this context. The problem statement underscores the pressing need to explore sustainable solutions for improving air quality, particularly in metropolitan areas where pollution levels are often elevated. The objectives of the study include investigating the correlation between urban green spaces and air quality, identifying key factors influencing this relationship, and assessing the effectiveness of green spaces in reducing air pollution. Limitations of the study are acknowledged, including potential constraints related to data availability, sample size, and external factors that may influence air quality measurements. The scope of the study focuses on a specific metropolitan area, considering the spatial distribution of green spaces, air quality monitoring stations, and relevant environmental factors. The significance of the study lies in providing empirical evidence to support the role of urban green spaces as a sustainable solution for improving air quality and enhancing the overall well-being of urban residents. The structure of the thesis outlines the organization of the research work, including the chapters and sub-sections that will be covered in the study. Definitions of key terms are provided to clarify the terminology used throughout the thesis, ensuring a common understanding of relevant concepts in the field of environmental science. The literature review examines existing research on urban green spaces and air quality, synthesizing key findings and identifying gaps in the current knowledge base. The review covers topics such as the impact of vegetation on air quality, the mechanisms involved in air pollution removal by plants, and the benefits of green infrastructure in urban areas. The research methodology details the approach taken to collect and analyze data, including the selection of study sites, data collection methods, and statistical techniques employed to assess the relationship between green spaces and air quality parameters. The methodology also addresses potential sources of bias and limitations in the data analysis process. The discussion of findings presents the results of the study, interpreting the data collected and assessing the significance of the findings in relation to the research objectives. The analysis considers the effectiveness of urban green spaces in reducing air pollution, the spatial distribution of pollution levels in relation to green spaces, and the factors influencing the impact of vegetation on air quality. In conclusion, the study highlights the importance of urban green spaces as a sustainable strategy for improving air quality in metropolitan areas. The findings support the hypothesis that green spaces have a positive impact on air quality by reducing pollution levels and enhancing environmental quality. Recommendations for future research and policy implications are discussed, emphasizing the need for integrated urban planning approaches that prioritize the preservation and expansion of green spaces to promote healthier and more livable cities.

Thesis Overview

The project titled "Assessing the Impact of Urban Green Spaces on Air Quality in a Metropolitan Area" aims to investigate the relationship between urban green spaces and air quality within a metropolitan setting. Urban areas face significant challenges related to air pollution due to vehicular emissions, industrial activities, and other anthropogenic sources. Green spaces, such as parks, gardens, and urban forests, have been recognized for their potential to mitigate air pollution by acting as sinks for pollutants and promoting natural air filtration processes. The research will delve into the specific mechanisms through which urban green spaces influence air quality, considering factors such as vegetation types, spatial distribution, and proximity to pollution sources. By conducting a comprehensive assessment of air quality parameters within and around urban green spaces, the study seeks to quantify the impact of these natural environments on pollutant concentrations, particulate matter levels, and overall air quality standards. Furthermore, the project will explore the broader environmental and public health implications of improving air quality through urban green space management. This includes potential benefits such as enhanced biodiversity, carbon sequestration, and psychological well-being for urban residents. By evaluating the multifaceted impacts of green spaces on air quality, the research aims to provide valuable insights for urban planning and policy formulation aimed at sustainable urban development and environmental conservation. Methodologically, the research will employ a combination of field measurements, air quality monitoring, spatial analysis, and statistical modeling techniques to assess the relationship between urban green spaces and air quality indicators. Data collection will involve sampling air pollutants at various locations within the metropolitan area, including both green spaces and control sites, to compare pollutant levels and assess the effectiveness of green infrastructure in air quality improvement. Overall, this research overview highlights the interdisciplinary nature of the study, bridging environmental science, urban planning, and public health to address pressing challenges related to urban air quality management. By investigating the impact of urban green spaces on air quality within a metropolitan context, the project aims to contribute valuable knowledge to the fields of environmental sustainability, ecosystem services, and urban resilience.
