Women have played, and continue to play, a prominent and critical role in conflict resolution and peace-making processes in many different parts of the world. Women in the highlands of Papua New Guinea are no exception. The author, drawing on her experience as a founding member of Kup Women for Peace, discusses the origins, character and progress of some recent womens initiatives in Simbu Province directed at stopping endemic tribal fighting and building the foundations of a just and sustainable peace. There are two overlapping dimensions: tribal fighting and violence directed against women and girls.
