It's time now for the Daily Discourse, and this morning we focus on the women leading efforts to tackle gender-based violence, gambling-related harm and other social challenges. While today's guests are from South Africa, the issues they're addressing resonate across Africa, where communities continue to grapple with violence, addiction and the need for stronger prevention and advocacy.  As many countries across Africa work to combat gender-based violence, advocates say lasting progress will depend on prevention, community action and stronger support for survivors.  Peter Ndoro spoke to Dr Lesley Ann Foster, Founder and Executive Director of Masimanyane Women's Rights International, a South African non-governmental organisation that works to prevent gender-based violence and advance the rights of women and girls.
