Sponge cities beating urban heat in China

Zhuhai, a city of 2.4 million in the Guangdong-Hong Kong-Macao Greater Bay Area, is not what you might picture a city at the heart of the world’s most populous area to be. With 708 urban parks, tree-lined waterfront promenades, and a connection between sea and mountain, Zhuhai is a tourism destination known as a forest city.
