Through a specific design project sited at the confluence of three rivers (Black, Amazon, and Mindú), Manaus argues for a new contractual agreement between city and territory by looking beyond the traditional definitions of cities and what constitutes the urban in the context of the Amazon Rainforest. The city of Manaus exemplifies the predominant disconnect between city and the soils of urban Amazonia. Western models of urbanization in the region continuously since the 1500s have cleared the forest rather than engage it, conceiving of cities as external to their immediate, botanical environs. Sited along the Mindú River, a spine that connects the Black River to the Reserva Florestal Adolpho Ducke, the project proposes a series of urban interventions that forge a new civic infrastructure fostering social and economic cooperation between the cycles of the river, forest, and city. Through the careful examination of five archetypal elements—the tower, the mat, the linear bar, the island, and the bridge—the project proposes an urban imaginary that advocates for the co-existence of ecological conservation and urban development, tempering the harsh divide between city and forest in the Amazonian region.
