Born and raised in Bogota, Colombia, Marcela Casas lived in the US for most of her adult life before moving to South Africa in 2006. Her academic background includes a Master’s in public administration and international affairs from Syracuse University. She has worked in policy and advocacy for almost ten years in organisations including The Carter Center, CIVICUS: World Alliance for Citizen Participation and Fairtrade Africa. Marcela Casas believes streets can bring people together. “In a city with a history of division and segregation, an Open Streets programme could profoundly change how we relate to each other,” she says. She is passionate about cities, public space and most importantly, people. Open Streets is a concept that resonates strongly with her because of her upbringing and the potential it has shown in Cape Town. Casas is also a cofounder of SUR Collective, a platform for cultural exchange between Latin American and Sub-Saharan African countries and was a contributor to the African Centre for Cities’ Serious Fun project in 2014.
