In this text urban researcher Prof. Dr. Maria da Silveira Lobo compiles some of the key facts about Megacity formation in Brasil, and reflects on event architecture and the spectacularisation of the City as well as on the role of NGOs. In November 2007 Ina Zwerger and Armin Medosch went to interview Maria for the forthcoming radio programme Brazil: Laboratory of the Future. Maria was so friendly to compile this text as a primer for our research. We thought that this text is an excellent resource, which should be made available to the public online.
