The Future of Everything with Russ Altman: Newsha Ajami: How engineers restored hope for our water supplies There was a time when all great cities were built near water. Whether for agriculture, aesthetics, energy or just plain drinking, water was a life-affirming, life-sustaining resource. But with the advent of advanced engineering in the form of dams, pumps and pipes, cities like Los Angeles thrived in places with very little fresh water. Now, global climate change is leaving many of those cities in danger of running dry. But there is hope on the horizon, says Newsha Ajami, senior research engineer at the Woods Institute for the Environment and director of urban water policy with Stanford University’s Water in the West program. Just as engineering made it possible to store and pump fresh water great distances, the field is developing new ways to use less water, to store more of this prized resource, to repurpose used “gray water” for non-potable uses like agriculture, and to inform inventive policy appro
