URBAN GREEN INFRASTRUCTURE: A SUSTAINABLE SOLUTION FOR AIR POLLUTION

Abstract

Urban green infrastructure (UGI) has emerged as a sustainable and multifunctional solution to address the escalating problem of air pollution in cities. By integrating natural and semi-natural systems such as parks, green roofs, urban forests, and vegetated walls into urban planning, UGI helps filter airborne pollutants, mitigate heat islands, and improve public health. This paper explores the mechanisms through which green infrastructure contributes to cleaner air, examines successful global case studies, and discusses design strategies for maximizing air quality benefits. The study also highlights the socio-environmental co-benefits of UGI, such as enhanced biodiversity, carbon sequestration, and improved urban resilience. As cities worldwide face increasing environmental stress, investing in urban green infrastructure presents an effective, cost-efficient pathway to achieving sustainable urban development and environmental justice.
