Ending violence against women and girls is a vital developmental challenge for Pacific Island countries, with several country studies having documented high levels of violence against women. The problem is particularly acute in Melanesian countries. Responding to endemic levels of violence against women, many Pacific Island countries, in association with bilateral and multilateral partners, have embarked on legislative reform. Approaches to prevention, however, are less well-developed, and there is increasing recognition of the importance of community-based approaches to prevention. Through our research we are seeking to understand the drivers of violence and how to mitigate it.
