This report summarizes the USAID project titled "The Role of Religious Communities in Addressing Gender-based Violence and HIV". Recognizing the importance of collaborating to prevent and reduce gender-based violence (GBV) and HIV among women and girls, the Initiative partners formulated the project to improve the capacity of religious leaders and faith-based organizations (FBOs) to respond to GBV and its links to HIV. FBOs, religious communities and, in particular, religious leaders, are often key catalysts for positive social change. Religious leaders are key stakeholders in responding to health and social issues and can play an influential role in validating and promoting best practices for preventing and reducing GBV and related vulnerability to HIV in their communities.
