The synchronization of hydrotemporalities in fishing territories: Debating time and history in the Llanito swamp, Magdalena River (Colombia)

• Hydrotemporalities shape and reshape territories. • Diverse actors synchronize time as a means of exerting power. • River synchronization reflects both the acceleration and compression of time. • Emerging capitalist dynamics embody increasingly faster temporalities. • Artisanal fishing encapsulates micro and macro temporal processes. This article introduces the concept of hydrotemporalities to analyze the history of the fishing hydrosocial territory of Llanito Swamp in the Middle Magdalena River. Specifically, this research contributes to debates on the temporal dimensions of water ecosystems territorialization and how political disputes become materialized as a result of competing assertions of time. Using methodologies of oral history and ethnographic interviewing, we argue that the history of this fishing hydrosocial territory has been shaped by different hydrotemporal forces, such as biorhythms, productive time, labour time, machinery time and memorial time. In this context, we demonstrate how diverse actors—including landlords, private-sector hydropower companies, and the state as represented by the public oil company—have sought to synchronize the river’s temporalities through diverse mechanisms, to serve their own interests at the expense of grassroots actors. We reflect on how this synchronization of the river represents an acceleration and compression of time, driven by the demands of emerging capital dynamics in the swamps, challenging the historically developed livelihood opportunities and cultural identities of fisher’s communities.
