The figure, depicted with glasses and dark hair, leans over a tabletop model featuring green spaces, trees, a winding blue river, and pathways. Surrounding the greenery are simple representations of buildings and infrastructure. The design emphasises harmony between urban development and nature, promoting sustainability and green urban planning. Illustration by Rosanna Wan for C40 Cities.
