Investigating the impact of urban green spaces on air quality in a metropolitan city.

Thesis Abstract

Abstract
This thesis investigates the impact of urban green spaces on air quality in a metropolitan city. The relationship between urban green spaces and air quality has gained significant attention in recent years due to the increasing urbanization and environmental concerns. The objective of this study is to analyze the effectiveness of urban green spaces in mitigating air pollution and improving air quality within a metropolitan city setting. The research methodology employed a mixed-methods approach, combining quantitative data analysis and qualitative research techniques. The study conducted air quality measurements at various urban green spaces and control locations to assess the levels of air pollutants such as particulate matter, nitrogen dioxide, and ozone. In addition, surveys and interviews were conducted with residents and stakeholders to understand their perceptions of urban green spaces and their impact on air quality. The literature review highlights the importance of urban green spaces in promoting environmental sustainability and public health. Previous studies have shown that green spaces can act as sinks for air pollutants, reduce heat island effects, and enhance overall air quality in urban areas. However, the effectiveness of green spaces in mitigating air pollution may vary depending on factors such as vegetation type, size of green space, and proximity to pollution sources. The findings of this study suggest that urban green spaces play a crucial role in improving air quality in metropolitan cities. The analysis of air quality data revealed lower concentrations of air pollutants in areas with greater green space coverage compared to control locations. Residents and stakeholders also expressed positive perceptions of urban green spaces and their benefits for air quality and overall well-being. In conclusion, this thesis provides valuable insights into the impact of urban green spaces on air quality in metropolitan cities. The results highlight the importance of incorporating green infrastructure into urban planning and design to enhance air quality and create healthier environments for residents. Further research is recommended to explore the long-term effects of urban green spaces on air quality and to develop strategies for maximizing their benefits in urban settings.
