In a context of cultural and traditional practices in Northen Cameroon, the patriarchy system has created gender inequalities between men and women with many consequences on women and girls. The Boko Haram crisis has worsened the situation with women and girls being most affected by sexual and gender based violences leading to severe trauma. On this backdrop, Marthe Wandou founded the non-profit NGO Action Locale pour un Développement Participatif et Autogéré (ALDEPA) in 1998, working with community-based approaches, effective strategies and tools in rural communities and schools. Girls’ clubs, child protection committees, peace and non-violence clubs, positive masculinity ambassadors are some community organisations that ALDEPA helped to establish, to address the root problems and to bring sustainable solutions to reinforce legal frameworks, sensitization, and capacity building, and to change the situation with real positive impacts for women and girls.
