This note sets out practical steps that can be taken by Humanitarian Coordinators (HC) and Country Teams (HCT) to ensure that Gender-Based Violence (GBV) prevention and response is prioritized, integrated, and implemented in system-wide humanitarian response. In the new HCT terms of reference endorsed by the IASC principals, GBV is one of the four mandatory responsibilities along with the centrality of protection, Accountability to affected people (AAP), and Protection from sexual exploitation and abuse (PSEA), and demands HCT members’ collective approach.
