Abstract

In the context of urban Asia, where air quality degradation poses significant challenges, the role of green infrastructure in enhancing air quality emerges as a crucial avenue of exploration. This study delves into the complex interplay among key variables-traffic density, vegetation coverage, green infrastructure density, and air quality improvement—within the Asian urban context. Leveraging a quantitative methodology, the research draws insights from 300 respondents representing diverse Asian countries. Quantitative analysis of the collected data unveils the intricate relationships between these variables. The findings shed light on the positive correlation between higher green infrastructure density and enhanced air quality. Furthermore, the study underscores the importance of vegetation coverage as a mediator that amplifies air quality improvement in the presence of abundant green infrastructure. The role of traffic density adds complexity, revealing unexpected correlations that require further exploration to grasp the nuanced dynamics. In the Asian context, where densely populated cities often grapple with poor air quality, this study contributes to evidence-based urban planning and policymaking. By quantitatively unraveling the relationships between green infrastructure, traffic density, vegetation coverage, and air quality improvement, the research equips stakeholders with insights crucial for fostering sustainable and liveable urban environments. As cities strive to balance growth with environmental concerns, the findings inform strategies that harness the potential of green infrastructure to pave the way for cleaner, healthier, and more resilient cities across Asia.
