Making a reservoir: Heterogeneous engineering on the Kemi River in Finnish Lapland

This article tells the story of long-lasting and ongoing struggles surrounding the construction plans for a major reservoir on the headwaters of the Kemi River in the Finnish Province of Lapland. A point of contention since the beginning of hydropower development on the river in the mid twentieth century, the reservoir project has been promoted and abandoned multiple times in waves of land purchasing, legal procedures, opposition campaigns, and the delineation of nature reserves. Despite a Finnish Supreme Administrative Court ruling officially setting an end to the project, it never entirely left public discourse and is currently being re-negotiated in slightly adapted form. Articulating voices and documenting practices of riverbank inhabitants, activists and hydro electricity managers, this article presents the struggle as multiple modes of heterogeneous engineering, where both proponents and opponents work towards creating different realities. The article develops the metaphor of heterogeneous engineering by drawing attention to three temporal dimensions central to the reservoir struggle: moments, which refer to the situated emergence of practices and strategies; futures, which speak to the attempts to build and contest expectations regarding conflicting projects; and durations, which consider the cumulative aspects of a decades-long struggle on people and landscapes. Thereby, the article contributes to discussions on making, planning and environmental management, and illustrates ways of studying these processes as situated practices in relation to time.
