Past droughts show that the current water shortage is not only a challenge, but also "an opportunity for making California's water system better able to support its cities, farms and environment," says Ellen Hanak, senior fellow at the Public Policy Institute of California (PPIC). Hanak's comments appeared recently in the San Francisco Chronicle as an Op-Ed co-authored by Jay Lund, director of the Center for Watershed Sciences, and Jeffrey Mount, center co-founder and a PPIC senior fellow.
