Editor's Summary: Prof. Dan Tarlock and Sarah Bates suggest that water scarcity is unlikely to curtail population growth in the American West, but that urban areas should still take into account water supplies as they plan for their futures. Thomas Graff and Jennifer Pitt agree that water availability is unlikely to inhibit growth in the West, but discuss the importance of ensuring that the right mix of forward thinking officials, an educated public, and a transparent decisionmaking process regarding water allocation are used to manage water resources. Benjamin Grumbles believes that smart growth policies coupled with reducing water waste and inefficiency, reusing water, and restoring watersheds can help ensure water security. David Hayes believes that the devolution and disaggregation of institutional control over water resources along with the reality of climate change may cause water supply and growth to be more closely connected than Professor Tarlock and Ms. Bates believe.
