In this module, an introduction to urbanization is provided through a series of videos about the origin of cities, population projections, and demands on infrastructure. You will also find examples of city infrastructure from Toronto, London and Tokyo and from Lagos, Kigali, and Dar es Salaam. In addition to the end of module quiz, you’ll have a chance to join the discussion by contributing your thoughts on the role that engineers can take to address the demands on infrastructure due to rapidly growing populations.
