OPINION — When a drought turns into an urban water crisis, a city’s first step is often to limit lawn watering and launch a campaign to encourage everyone to conserve. It might raise water-use rates or offer incentives for installing low-flow devices.
While demand management techniques like these have had a lot of success in reducing water use, our new research suggests that they may not be effective enough in the face of climate change.
We looked at three cities in the Colorado River Basin — Phoenix, Las Vegas and Denver — to understand what each could do to increase demand management amid water shortages and how far those methods could go as temperatures rise and the Colorado River’s flow weakens.
