Gender-based violence (GBV) is a significant obstacle to women’s enjoyment of their rights and a violation of their fundamental freedoms. In several countries, particularly in West Africa, such violence is rooted in a social system founded on patriarchy. This system generates and perpetuates negative social stereotypes and prejudices towards women. West Africa continues to be marked by persistent socio-cultural constraints and harmful traditional and customary practices, which contribute to the rise in violence against women in their communities. This study explores the GBV situation in West Africa, particularly in countries such as Senegal, Mali, Burkina Faso and Niger. More specifically, it attempts to answer the following questions: What is the environment in which gender-based violence is committed in the target countries? How can the legal framework for the fight against GBV be analysed? What are the best practices and recommendations for addressing GBV?
