Systematic Review of Air Quality Management in Urban Environments: Planning for Healthy Cities Using the One Health Approach

<i>Background: </i>Air Quality Management in urban environments is a planned and interdisplinary practice expected at follow up, regulatory, and decreasing air contamination to keep community well-being and the atmosphere. Through fast development, people growing, and urban motor traffic growth, numerous municipalities particularly in Global south countries expression thoughtful air quality encounters. The aim review evaluates air quality management in urban environments with emphasis on planning for healthy cities. <i>Methodology</i>: The systematic review observes global compositions evaluating air quality administration methods, through an emphasis happening controlling contexts, wellbeing influences, checking systems, and city development policies. Databases containing PubMed, Web of science, and Google Scholar remained used to identify peer-reviewed articles, official reports, and case studies. After applying inclusion and exclusion criteria, 55 documents were selected for thematic analysis. Important themes included pollution sources, health and environmental impacts, urban planning strategies, technological innovations, and policy frameworks. <i>Results:</i> Results show that though industrialized countries require applied organized air quality administration methods reinforced through law for instance the U.S. Clean Air Act and EU Air Quality Directives, where unindustrialized nations fight through split strategies, inadequate statistical records, and inadequate official capability. Progressive tackles for example low-cost sensors, digital urban twins, and real-time pollution forecasting are existence progressively accepted to increase policymaking. Municipalities that combined air quality administration with city forecasting established better wellbeing results, counting compact respiratory and cardiovascular diseases. Though, important obstacles persist, for instance inadequate finance, administrative resolve, and community commitment. <i>Conclusions:</i> Operative city air quality managing is vital to design for healthy metropolises. The evaluation highlights that effective air quality controlling needs robust authority, consistent facts, innovative skills, and lively investment participation. Metropolises obligation implant air quality deliberations into wider ecological and growth rules to accomplish permanent developments. City air pollution finished complete and comprehensive policies should be serious intended for protection community wellbeing, attaining weather objectives, and making strong city surroundings.<i>
