This research project engages artists and experts from diverse fields in hydro-ecological research. The aim is to provide multiple perspectives on hydrological matters of concern. Drawing on Bruno Latour’s political ecology and Donna Haraway’s materialist philosophy, this research project responds to the latest developments in ecological thinking and takes an innovative stance by developing a genuinely interdisciplinary research objective, research methodology, and output. Rather than reflecting from within their field of study, the researchers engage in a Natural Contract LAB, a long-term research-based art project initiated by the Portuguese, Ghent-based artist Maria Lucia Correia. The LAB fosters new modes of knowledge production and new modes of activism in relation to ecological matters of concern. The participants engage in several multi-day expert workshops that seek to activate awareness on the particular ecological topic of water (re-)distribution of the river Lys in Flanders, Ghent. The following research questions are at stake: How does water flow through, across, and between human and more-than-human bodies politically, socially, and environmentally? How do we design a process of repair based on reciprocity, accountability, and interdependency with certain waterways? Do we need other ways of making justice and gestures of care for bodies of water?
