In partnership with UNDP Sierra Leone, this project studied the prevalence, incidence, trends and patterns of sexual and gender-based violence (SGBV) within Sierra Leone via a parallel, mixed-methods methodology. Through analysis into the root causes of SGBV, the report sought to provide evidence that would form the basis for targeted policy recommendations to prevent and respond to this phenomenon through a unified national response. Close collaboration with the Sierra Leonean government generated recommendations that can guide the development of policies and programs to promote the attainment of the highest level of sexual and reproductive health and rights for all people; as well as policies targeting the reduction of incidence of HIV, GBV prevention, and survivor support services.
