This thesis is a detailed analysis of the factors that contributed to the emergence of environmental injustice in Estrutural, Brasília. It evaluates the current socio-spatial configuration of people and waste in this urban area by drawing a longitudinal comparison showing how hazards and people's relationship to hazards have changed over time. In order to evaluate environmental inequities in Estrutural, first, this thesis addresses the motives that caused socio-spatial segregation and environmental degradation in the city of Brasília by developing a historical-geographical evaluation of Estrutural. Second, it asks who these people are and what their motives are for living in Estrutural by using open-ended questions to interview eleven residents. The goal of this thesis is to contribute to the conceptual framework of environmental justice and to develop a methodology to study environmental injustice in Brazil.
