Dr Theresa Williamson, Executive Director, Catalytic Communities
Hosted by Dr Nick Morgan, introduction from Dr Matt Davies
Informal settlements, such as Rio de Janeiro’s favelas, are not new and they are not rare. Today, one in three people in cities live in an informal settlement, and 85% of all housing worldwide is built illegally. By 2050, nearly a third of humanity will live in urban informal settlements. How can we value informal settlements around the world and integrate them on their own terms into our urban planning practices? Could this search lead to a sustainable urban future?
