World Cities Day is celebrated every year on October 31st to promote global awareness about the importance of sustainable urban development. It was first observed in 2014, established by the United Nations to highlight how cities can be inclusive, safe, resilient, and sustainable.As more people move to cities, the challenges of housing, pollution, transport, and climate change continue to grow. World Cities Day reminds us that urban areas are not just centers of population, but hubs of innovation and culture. It encourages cooperation among nations, communities, and individuals to make cities better places for everyone.The theme for each year focuses on key urban issues, such as smart cities, climate action, and green infrastructure. By working together, we can build cities that offer equal opportunities, protect the environment, and improve the quality of life for all citizens.
