Fifty million people in the world today are victims of forced relocation caused by wars and violence. Whole new countries are being created, occupied by Afghan refugees, displaced Columbians, deported Rwandans, exiled Congolese, fleeing Iraqis, Chechens, Somalians and Sudanese who have witnessed wars, massacres, aggression and terror.

New populations appear, defined by their shared conditions of fear and victimhood and by their need to survive outside of their homelands. Their lives are marked by the daily trudge of dislocation, refugee camps, humanitarian help and the never-ending wait. These populations are the emblems of a new human condition which takes shape on the very margins of the world.

In this remarkable book Michel Agier sheds light on this process of dislocation and quarantine which is affecting an ever-growing proportion of the world's population. He describes the experience of these people, speaking of their pain and their plight but also criticising their victimization by the rest of the world.

Agier analyses the ambiguous and often tainted nature of identities shaped in and by conflicts, but also the process taking place in the refugee camp itself, which allows refugees and the deported to create once again a sense of community and of shared humanity.

Michel Agier is Director of the Centre for African Studies at the Ecole des Hautes Études en Sciences Sociales, Paris.
