Green Infrastructure and Urban Planning for Sustainable Clean Air

In the face of rapid urbanization and escalating environmental concerns, the concept of green infrastructure has gained significant traction in urban planning circles. This chapter explores the integral relationship between green infrastructure and urban planning in fostering sustainable clean air. By examining the multifaceted benefits of green infrastructure, such as mitigating air pollution, enhancing urban biodiversity, and improving public health, this chapter underscores its critical role in addressing the pressing challenge of urban and suburban air quality. Moreover, it highlights the importance of collaborative efforts among policymakers, urban planners, environmentalists, and communities in realizing the potential of green infrastructure to create healthier and more livable cities. Drawing upon principles of landscape ecology, environmental design, and urban governance, the chapter delineates various typologies of green infrastructure interventions, ranging from vegetated corridors and green roofs to urban forests and permeable surfaces. By harnessing the natural capacities of vegetation, soil, and water, these interventions not only mitigate air pollution through pollutant filtration and carbon sequestration but also confer ancillary benefits such as heat island mitigation, stormwater management, and biodiversity conservation. The chapter underscores the significance of integrated planning approaches that transcend traditional sectoral silos, fostering synergies between land use planning, transportation design, and environmental management. In conclusion, by leveraging emerging technologies for monitoring air quality to fostering interdisciplinary collaborations between planners, scientists, and policymakers, it delineates a roadmap for harnessing the full potential of green infrastructure as a cornerstone of sustainable urban development.
