"African states and governments need to be sensitised about their obligations towards IDPs, and about IDPs' rights under the African Charter, their respective constitutions and national laws. Urgent attention should be directed at the root causes of displacement in Africa. The absence of a binding international legal regime on internal displacement is a grave lacuna in international law," states Bahame Tom Nyanduga, Special Rapporteur on Refugees, IDPs and Asylum Seekers in Africa for the African Commission on Human and Peoples' Rights. Nyanduga was writing in the September issue of Forced Migration Review.
