Tackling violence against women and girls isn’t just about supporting survivors. It’s about changing attitudes and challenging the inequalities at the heart of gender-based violence. Thomas Ochieng is doing just that. He’s the station manager at Ruben FM, a community radio station in Mukuru - a large slum to the east of Nairobi. Alongside ActionAid partner, the Wangu Kanja Foundation, Thomas and his team are raising awareness about gender-based violence. They're using the airwaves to challenge sexual violence and get ActionAid's message out into the community.
