By imagining a future contingent on infrastructural, monumental, and social palimpsests, a new story about sovereignty is told; one that incorporates the voices of territories, citizens, and natural processes. Through a sequence of reciprocal actions that gradually increase in scale, scope, and impact, a formerly fractured Guantanamo Bay reunifies people, ecologies, and economies. First, a series of political exchanges between the U.S. and Cuba restores access to water on both sides and serves as the impetus for uniting the fragmented estuary. Next, the obstructive water fence is replaced by a network of connective water landings, restoring flows of circulation. Then, the closure of the U.S. naval base provides the opportunity to dismantle the vacated structures; repurpose the materials for the construction of reefs, runways, and roads; and create a cycle of reciprocity between hydrological and land-based systems. Finally, at the global scale, a mature fishing industry invigorates the local economy. The simple act of understanding the estuary through a collapsed temporal scale holds the potential to catalyze a new set of social, ecological, and economic relationships. Guantanamo Bay is reclaimed and reconstituted, a transformation that is observed in the creation of a new figure-ground: one which dissolves the distinction between upstream and downstream, land and water, past and future.
