The ongoing military action in Afghanistan is deepening what was already a severe humanitarian crisis. Further displacement of civilians will have a profound impact upon the ability of the country and its people to recover. The movement of civilian populations in search of security, as a result of conflict, or food, as a result of drought, has characterized the long conflict in Afghanistan. The continuing flight of civilians from urban areas, in the face of aerial attacks, compounds a humanitarian situation that was already grave, due to a long and devastating drought in many parts of the country. Over the coming winter, more than a million internally displaced persons (IDPs) will require emergency assistance simply to survive. Apart from the immediate impact on the livelihoods of the displaced and their hosts, forced movement affects social relations and traditions within affected communities. It is important to take stock of these changes, and related shifts in community- or tribal-level politics that might occur during displacement, in efforts to support the recovery of vulnerable communities. This policy brief aims to provide a concise point of reference for those planning responses to the complex range of issues resulting from displacement. It includes a number of active links to the most relevant and reliable information sources. It concludes with a range of operational recommendations for international organizations, governments and NGOs working on this issue.
