Social practice theory and household water demand: A review of literature and research evidence

The changing climate, rapid increases in global consumption, and shock events are increasing stress on water resources globally. For policy makers and water sector stakeholders tasked with reducing demand, and for academic researchers interested in understanding how these complex issues intertwine to create current and future water demand profiles, the shortcomings of individualized behavior change approaches driven by psycho-econometric understandings of resource consumption is increasingly evident. Since the early 2000s, social practice theory has been increasingly recognized as deepening understandings of the complex ways water is consumed and the dynamic factors that influence household demands. This review examines evidence of how social practice ideas are deployed in academic research in scope (theory; geographical; practices entities/performances; sites, locations, and temporality of practices; infrastructural configurations); methods (historical; talk—interviews, focus groups; diaries; ethnography and home tours; surveys; living labs, experiments, design methods; mixed methods); and implications (co-production; materiality; diversity; disruption and insecurity; inequalities) including for policy and practice. Emerging from the review is a set of ideas that demonstrate how to apply insights from social practice more effectively in water studies and in water management, aiding the exploration of new areas of enquiry, policies and mechanisms to enable less intensive patterns of water use. This review points to a need for increased collaboration across the water sector and wider stakeholders to enact deep and meaningful change to how water is supplied and consumed in society.
