Forced displacements caused by large companies’ actions are increasingly frequent in Latin America. The Braskem case is named after the Brazilian petrochemical company who exploited rock salt mining during more than 40 years in the urban environment, without inspection and culminating at land subsidence in Maceio, Brazil. The disaster has affected more than five neighbourhoods, impacted more than 200,000 people, and displaced more than 60,000 people in Maceio, the capital of the state of Alagoas. It is the largest urban tragedy in a densely populated urban area in the world, with unprecedent outcomes. This disaster still cries out for visibility and reparation. The challenge of harmonising economic development with human development and environmental protection is the starting point of this chapter, considering the United Guiding Principles on Business and Human Rights. In sequence, it analyses the Braskem case from the perspective of the United Nations Guiding Principles on Internal Displacement highlighting the complexity of protecting internally displaced people (IDPs) in Brazil. Finally, it discusses the implementation of a Network Society Communicative Model to the case, in order to protect IDPs.
