Abstract: Purpose: The aim of the study was to assess the impact of urban green spaces on air quality in metropolitan areas. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Research on the impact of urban green spaces on air quality in metropolitan areas has yielded promising findings. This study indicate that the presence of green spaces, such as parks, gardens, and tree-lined streets, can significantly mitigate air pollution levels. Vegetation acts as a natural filter, trapping particulate matter and absorbing harmful pollutants like carbon dioxide, nitrogen dioxide, and ozone. The vegetation also facilitates the dispersion of pollutants through processes like deposition and absorption, thereby reducing their concentration in the air. Implications to Theory, Practice and Policy: Biophilia hypothesis, ecosystem services framework and green infrastructure theory may be used to anchor future studies on assessing the impact of urban green spaces on air quality in metropolitan areas. Implement strategic urban planning initiatives that prioritize the preservation, expansion, and equitable distribution of green spaces within metropolitan areas. Develop evidence-based policies and regulations that incentivize the integration of green infrastructure into urban planning and development processes.
