Urban Green Infrastructures and Its Impacts on the Urban Environment: A Review

Abstract

Urban green infrastructure plays a crucial role in preserving a green urban environment, thus contributing significantly to human health. The absence of such infrastructure can lead to environmental challenges, particularly in the face of escalating global urbanization. Green urban infrastructure proves essential for maintaining cleanliness in urban areas, especially as major cities worldwide grapple with escalating air pollution exacerbated by the inadequate presence of green spaces, green roofs, green walls, and domestic and private gardens emerge as noteworthy contributors to mitigating these challenges. As the global population steadily increases, a collective effort is imperative to enhance green infrastructure and cultivate public awareness to address the pressing issue of air pollution in cities. Green spaces serve as a pivotal indicator of urban verdancy, offering a myriad of benefits, including environmental cleanliness, the creation of recreational spaces, the promotion of health and well-being, the facilitation of children’s mental development, the presentation of aesthetically pleasing urban landscapes, temperature reduction, and pollution mitigation. This comprehensive review analyzed 60-70 studies on urban green infrastructures and their impacts on the urban environment. A library research methodology was used, focusing on literature from Google Scholar published in the last two decades which delves into the multifaceted aspects of urban environmental cleanliness, providing valuable insights for policymakers, and urban planners with a profound understanding of their impacts. Stakeholders can proactively implement measures to enhance cleanliness in the urban environment.
