“Urban Palisades” examines the development of the district of Santa Fe to interrogate the role of technologies in cementing socioeconomic segregation in contemporary Mexico City –one of the world’s most unequal megalopolis. This interdisciplinary research project contends that any critical analysis of urban inequality in the Global South requires attention to the historical construction of a built environment that functions as barriers and boundaries between the rich and the poor. This project examines “technological palisades” to explain how infrastructural systems and technological artifacts simultaneously embody and work to draw new geographies of urban inequality and social fragmentation. Four research questions drive the project: 1) How have technologies shaped the geography of urban inequality in the development of Santa Fe? 2) Who have been the main actors behind the material deployment of both Santa Fes? 3) How do technological palisades chart gendered spatial topographies? 4) To what extent are urban fragmentations created by infrastructures and other technologies reversible?
