Cities around the world are growing rapidly, causing problems like pollution and resource depletion. Sustainable urban planning is key to addressing these issues. In Shiraz, Iran, a study focused on creating a smart city plan to improve the environment and quality of life. By using modern technologies and involving the community in decision-making, energy consumption can be reduced and urban development can be more sustainable. However, challenges like lack of long-term planning and limited cooperation between people and government need to be addressed for successful implementation. The goal is to create a city that meets the needs of its diverse population while protecting the environment for future generations.
