The United Nations declared 31 October as World Cities Day in the General Assembly of 2013. The event aims to raise public awareness of the role of urbanisation in sustainable urban development and social inclusion worldwide.
The general theme of World Cities Day is "Better City, Better Life", while each year a different sub-theme is selected, to either promote successes of urbanisation, or address specific challenges resulting from urbanisation.
This year, the United Nations has selected the theme "Building Sustainable and Resilient Cities". Cities need to develop their capacity to absorb the impact of hazards, protect and preserve human life and limit damage to and destruction of public and private assets while continuing to provide infrastructure and services after a crisis. The main event will be celebrated in Liverpool, UK.
