As the world’s population increases by 80 million a year, and with the majority of people now living in cities. we face a chronic shortage of adequate housing in our urban centres. The worldwide credit crisis of 2009 was triggered by the collapse of the high-risk mortgage market in the US – in the West the shockwaves went deep: property prices crashed, jobs were lost and homes repossessed. In the developing world people are still moving to the cities in large numbers. When they can’t find accommodation they simply improvise their own shelter. The result is slums. One billion people currently live in slums and a staggering 25 million people a year are set to join them. In this BBC World Debate, supported by UN-Habitat, Lyse Doucet explores the subject with a panel of experts from around the world.
