Violence against women and girls is the most extreme manifestation of gender inequality. It is present in the home, in the community, and in political and policy making forums that govern the lives of women and girls. In humanitarian contexts, there is even more of a need for services and transformation whereby women and girls live free from violence but are also empowered to fully engage in personal, political, civic, social, and economic opportunities across various contexts. This Handbook and Facilitator’s Manual is a basic introduction to the issue of violence against women and girls, the scope and scale of violence they experience, and its long-lasting consequences in conflict-affected and post-conflict settings. It should be used to support and train new GBV staff as well as other humanitarian staff to implement programming that is grounded in gender equality and the needs, wishes, and dreams of women and girls in the places where they work. This training is current being updated and revised.
