Developing Novel Approaches to Tracking Domestic Water Demand Under Uncertainty—A Reflection on the “Up Scaling” of Social Science Approaches in the United Kingdom

Climate change, socio-demographic change and changing patterns of ordinary consumption are creating new and unpredictable pressures on urban water resources in the UK. While demand management is currently offered as a first option for managing supply/demand deficit, the uncertainties around demand and its' potential trajectories are problematic. In this paper we review the ways in which particular branches of social science offer a model of 'distributed demand' that helps explain these current and future uncertainties. We also identify a few potential strategies for tracking where the drivers of change for demand may lie. Rather than suggesting an alternative 'demand forecasting' technique we propose alternative methodological approaches that 'stretch out' and 'scale up' measures of demand to inform water resources planning and policy. These proxy measurements could act as 'indictors of change' to water demand at a population level that could then be used to inform research and policy strategies. We conclude by arguing for the need to recognise the co-production of demand futures and supply trajectories.
