Most research into the connections between water and energy, water and food, and food and energy has been scientific and technical; little research has examined the public’s understandings of these connections. This article studies these understandings and awareness of nexus issues using a 2015 national public opinion survey on the water–energy–food nexus. Responses from this representative sample of U.S. adults are used to create “awareness measures” for elements of the nexus—water and energy, water and food, and energy and food—which are then used as independent variables to investigate the extent to which awareness is associated with support for public policies designed to address these nexus interconnections. All three measures are significantly correlated to support for policy options. Results suggest that awareness of the water–energy–food nexus may represent conditions necessary for supporting policies and that building such awareness could represent an important pathway for increasing support for policy interventions.

Objective. This response to Lenahan O'Connell's article “Exploring the Social Roots of Smart Growth Policy Adoption by Cities” examines whether the relationship between education and the adoption of smart growth programs in U.S. cities is reflective of the new political culture and rooted in postmaterial values or, perhaps, just reflective of a slightly different way of thinking about traditional economic development. Methods. Using data for 45 U.S. cities that have articulated broad policies to try to become more sustainable, this analysis includes a measure of the severity of air pollution as an indicator of the need for smart growth programs. Results. The measure of need is more strongly related to the pursuit of smart growth than is either education or income. Conclusions. Since the level of air pollution is frequently understood to make economic growth difficult or impossible, the results suggest that smart growth programs might be just as likely motivated by traditional economic development as by postmaterial values, and there is a need to develop a deeper understanding of the motivates for adopting such programs.
