"With growing numbers of displaced people in towns and cities, humanitarian and development actors need to rethink approaches to helping the urban displaced live in security and with dignity"Forced Migration Review (FMR) provides a forum for the regular exchange of practical experience, information and ideas between researchers, refugees and internally displaced people, and those who work with them. It is published in English, Arabic, Spanish and French by the Refugee Studies Centre of the Oxford Department of International Development, University of Oxford. Globally, urbanisation “ the movement of people into cities and towns “ continues to increase, and growing numbers of displaced people, whether refugees or IDPs, now reside in urban areas rather than camps. Relatively little is known about their precise numbers, demographics, basic needs or protection problems. In their introductory articles in this issue of FMR, UN High Commissioner for Refugees António Guterres and UN-HABITAT Executive Director Anna Tibaijuka emphasise the complexity of the challenges faced by those displaced into urban areas and by those seeking to protect and assist them, and argue for the need for a radical rethinking of approaches by the international community. This issue of Forced Migration Review includes 26 articles by a wide range of authors “ practitioners, policymakers and researchers “ on the subject of urban displacement, plus 13 articles on other aspects of forced migration, including a ˜spotlight' on Haiti after the earthquake.
