Sustainable urban development aims to create livable cities by balancing environmental, economic, and social factors. It focuses on long-term viability and quality of life for urban residents, addressing challenges like resource use, pollution, and social inequity.
Key strategies include mixed-use development, transit-oriented design, and green infrastructure. These approaches promote walkable neighborhoods, reduce car dependency, and incorporate natural systems into urban spaces to manage environmental issues and enhance city life.
