Effectiveness of conservation messages to reduce households' GHG emissions: A serious-gaming experiment.

Households play a critical role in reducing greenhouse gas emissions. However, there have been few studies of household conservation from the perspective of the nexus of food, energy, and water (FEW) consumption. This study's objective is to understand the effects of different types of intervention messages for inducing conservation of FEW resources and reducing carbon emissions at the household level in the U.S. Employing a serious-gaming approach, we developed the HomeRUN (Home Role-play for Understanding the Nexus) game, which allows players to act as homeowners and take behavioral and technological upgrade actions in a computer-simulation setting. The types of messages tested include social comparisons and resource-reduction measures across FEW sectors as well as information about the health, economic, and environmental impacts of FEW consumption. A game experiment with U.S. university students finds that social-comparison messages on food and energy consumption, but not on water, lead to significant reductions in household carbon emissions. In addition, messages associated with each type of FEW resource tend to lead to an immediate action corresponding to the particular FEW domain. These insights support a prioritization of intervention messaging for coordinated FEW conservation efforts at a household level.

Green roles at home: exploring the impact of household social dynamic processes on consumption at the food-energy-water (FEW) nexus.

Capturing the social dynamic processes among household members that work to shape consumption patterns presents a complex problem for household resource conservation studies. To bridge the gap between the individual and household, we propose and test a series of quantitative measures that explore the underlying structure of household social dynamic processes through the lens of social practice theory. Based on previous qualitative research, we develop measures to test five distinct social dynamic processes that either encourage or deter pro-environmental action: enhancing, norming, preferring, constraining, and allocating. In a sample of households (n = 120) from suburban Midwestern USA, we find that positively framed social dynamic processes (enhancing and positive norming) positively predict variance in frequency of food-, energy-, and water-conserving pro-environmental actions. Pro-environmental orientation of the individual respondent, in turn, is positively associated with perception of positively framed dynamics. These findings suggest that social dynamic processes influence individual decision-making about household consumption, supporting previous research that illustrates consumption as embedded within the relationships that form residential life. We suggest ways forward for quantitative social science researchers to explore consumption through a practice-based approach that considers the influence of social institutions on emission-intensive lifestyles.

Understanding factors that influence stakeholder trust of natural resource science and institutions.

Building trust between resource users and natural resource institutions is essential when creating conservation policies that rely on stakeholders to be effective. Trust can enable the public and agencies to engage in cooperative behaviors toward shared goals and address shared problems. Despite the increasing attention that trust has received recently in the environmental management literature, the influence that individual cognitive and behavioral factors may play in influencing levels of trust in resource management institutions, and their associated scientific assessments, remains unclear. This paper uses the case of fisheries management in the northeast to explore the relationships between an individual's knowledge of the resource, perceptions of resource health, and participatory experience on levels of trust. Using survey data collected from 244 avid recreational anglers in the Northeast U.S., we test these relationships using structural equation modeling. Results indicate that participation in fisheries management is associated with increased trust across all aspects of fisheries management. In addition, higher ratings of resource health by anglers are associated with higher levels of trust of state and regional institutions, but not federal institutions or scientific methods.
