The Evolution of Urban Spatial Structure in Brasilia: Focusing on the Role of Urban Development Policies

초록

Many cities evolve over time, but some are designed from scratch. Brasilia is presented as a unique case on urban planning for having been built from figuratively nothing, based on a design concept that was the brainchild of Brazilian urbanist Lucio Costa. The present study aimed to analyze the interrelation between urban planning and spatial structure change over time to understand the role of urban development policies on the spatial organization of Brasilia. The study was conducted based on three interrelated aspects: (1) The intentions of the plans, (2) territorial governance, and (3) external conditions. The results showed that the circumstances of territory occupationcharacterized by a polycentric development system with dispersed satellite cities economically dependent on Brasiliahave been gradually replaced by strategic development policies, mainly influenced by social and political driving forces. Accordingly, this research suggests a reconsideration of the scale of development instrumentations based on a better understanding of the metropolitan area of Brasilia as a unique structure by strengthening its interrelations and seeking better coordination of interests and adaptability of governance processes.
