Connecting global conversations on ethical AI: the Coded Bias World Tour and AI in Africa: Challenges and Opportunities

In this episode Dr Caroline Green from Oxford's Institute for Ethics in AI speaks to Dr Joy Buolamwini and Angela Oduor Lungati, Executive Director of Ushahidi, about building ethical, community-centered AI from Africa and beyond. Angela discusses her work leading Ushahidi, an open-source platform used globally to crowdsource crisis and human rights data, and how community-generated knowledge can shape more inclusive and context-aware AI systems.Joy reflects on her journey from uncovering bias in facial recognition systems to founding the Algorithmic Justice League, sharing how her research - featured in the documentary Coded Bias - exposes the social harms embedded in AI.Together, they explore women’s leadership in technology, the importance of grassroots voices in shaping AI governance, and the need for data justice, language representation, and accountability across the AI supply chain. The conversation highlights Kenya’s national AI strategy, Africa’s growing role as a builder - not just consumer - of AI, and the environmental and labour impacts of AI infrastructure. The episode closes with reflections on creativity, humanity, and the role of art in guiding responsible innovation.
