There are some thirty million internally displaced persons (IDPs) today as compared to fifteen million refugees. The root causes generating refugees and IDPs are essentially the same: armed conflicts and human rights abuses. While refugees are protected by a number of international treaties and organizations, and are enjoying comparative safety in countries of asylum or resettlement, IDPs are not - supposedly on the ground that since IDPs are within their own country, their government should be responsible for their protection.
