To make a city "smart," it's not enough for it to be wired or high-tech and high-speed, according to urban development expert Tim Campbell.
It also has to be a city that can learn, innovate and operate in a "cloud of trust", he adds.
The renowned author moderated an event entitled "A Global Conversation on Cities" in Medellin, Colombia for the World Urban Forum 7 (WUF7).
Mr. Campbell has worked for four decades in urban development with experience in several countries and hundreds of cities in Latin America, South and East Asia, Eastern Europe, and Africa.
