Fundación Servicios Integrales para la Mujer - Si Mujer implemented the three-year project “Young People Challenging Gender Norms to Break the Silence that surrounds Sexual Violence in South-West Colombia” in Santiago de Cali and nearby municipalities in the state of Valle del Cauca, with the support of the UN Trust Fund from 2018 to 2021. The project aimed to address gender-based violence by empowering adolescents and youth to challenge harmful, unequal gender norms; lead community-based prevention and advocacy initiatives; and strengthen the capacities of civil society and public institutions to provide gender-sensitive services to survivors of sexual violence. The final evaluation found that the project successfully empowered and mobilized young people and leaders to challenge harmful gender norms, raise awareness on sexual violence, and advocate for their sexual and reproductive health rights.
