"[The Groundwork Guides] are excellent books, mandatory for school libraries and the increasing body of young people prepared to take ownership of the situations and problems previous generations have left them." -- Globe and Mail Today, more people live in cities than in rural areas. The search for better housing, transit, economic opportunity, and security within neighbourhoods forces today's city-dwellers -- in both the developed world and in megacities in Asia, Africa, and Latin America -- to confront what it means to live in our urban world. In this book, cities specialist John Lorinc considers the enormous implications of the mass migration away from rural regions, and predicts that solutions will emerge from neighbourhoods and dynamic networks linking communities to governments and the broader urban world.
