Close to 70 per cent of the world population lives in cities, which brings opportunities but also major challenges, many of which have featured high on the agenda at this week’s World Urban Forum (WUF12) in Cairo.

Successful urban development must include the perspectives of women and young people, according to the World Bank’s Global Director for urban resilience, who said it was vital to include their voice in decision making and how public space is used.
