How do nature and technology shape where water flows? How do they affect who has access to it? Using Paris as a case-study, Soppelsa examines the city's "waterscape" to investigate the place of water in society during a period where how Parisians used their water changed dramatically and became highly politicized. He raises fundamental questions about how humans and non-humans make ecological change. Soppelsa's talk resonates with today's debates on "water wars," water infrastructure, and water pollution.
