In Kandal province in Cambodia, preks crisscross the landscape, connecting rivers with floodplains, supporting rich ecologies and a variety of livelihoods. Drawing on science and technology studies (STS) and critical water research, this paper explores prek(s) as a multiplicity. Rather than taking the prek as a passive object around which various practices occur, we examine how prek(s) are enacted as ontologically different : as irrigation infrastructure, as pathway to rice intensification, as device for Cambodian state-making, and as climate-friendly agricultural development. After analyzing interference patterns between enactments and their scale-making effects in- and outside the Mekong floodplains, we make explicit our own ontological politics. Focused on sustaining multiple uses and ecosystems, 'our' prek is a socionatural mosaic landscape where many human and more-than-human actors and practices can coexist. This ontological politics, we suggest, has implications for planetary environmental knowledges and delta management far beyond Kandal's landscape. 062EVAEAU ; 098HYSOC ; 021ENVECO ; 095DEVEL
