Jane Anyango, founder and director of the Polycom Development Project, and Elsa Marie D'Silva, founder and CEO of the Red Dot Foundation, talk about addressing sexual violence in cities as a development challenge. "There’s a lot of sexual harassment in Kibera, [Nairobi], and at times, because of their financial status, girls end up accepting these people taking advantage of them because they have no option and they also have no one to share with when they’re being harassed," said Anyango.

Ruxanda Renita, cofounder of the Urban Catalyst Lab, discussed community-driven art as a tool for promoting community ownership of sustainability and urban development dialogues.
