Urban planning for sustainable cities involves designing spaces that prioritize environmental, social, and economic well-being. Strategies include compact, walkable layouts, efficient public transportation, and green spaces to mitigate pollution. Energy-efficient buildings and renewable energy sources reduce carbon footprints. Zoning laws promote mixed-use developments, minimizing commute distances. Community engagement fosters inclusivity and resilience. By integrating these practices, cities can create vibrant, livable environments that balance urban growth with environmental conservation.
