Our cities need to adapt to cope with more extreme weather events and other impacts from climate change.
A call to make our cities more resilient to climate change could drive one of the largest new infrastructure builds in history.
Tapping just 3.7% of solar potential in countries in China's intercontinental infrastructure programme could power the entire region.
Lagos was affected positively and negatively by Nigeria’s emergence as a crude oil producer in the 1970s.
The foundations of orderliness for any city are planning and management. Lagos had this in place in the early days.
Warning signs in the Newark Health Department after the city learned that lead service lines to houses still were contaminating water.
