Increases in urban populations, particularly in semi-arid cities, have led to unsustainable water use in many regions of the world. Water is frequently drawn from outside urban boundaries, but these remote water sources are becoming less reliable due to global climate change and regional political conflict. In response, urban water conservation efforts have been expanding and cities are pressured to reduce demand. Yet, as seen currently in California, measures to reduce water use are having limited effect (See, for example, www.theguardian.com/us-news/2015/may/05/california-falls-short-water-saving-target-drought). Can better data help to underpin water use policy?
