It is marked on the first Monday of October each year.
It was first celebrated in 1986 in Nairobi, Kenya and was recognized by the United Nations.
It is intended to remind the world that we all have the power and the responsibility to shape the future of our cities and towns.
The theme for this year is ‘Mind the Gap. Leave No One Behind and No Place Behind’.
This year seeks to draw attention to the growing inequalities and vulnerabilities that have been exacerbated by the Triple ‘C’ Crises: COVID-19, Climate and Conflict.
