Extension professionals can play a role in addressing water scarcity issues by helping home landscape irrigation users to conserve water. This study used survey research to examine the relationship between several variables, including attitudes, subjective norms, perceived behavioral control, personal norms, demographic factors, and past behaviors, on intention to use good irrigation practices among Florida home landscape irrigation users (N = 1,063). Following subsequent hierarchical linear regression models, the final model explained 39% of the variance in intentions to engage in good landscape irrigation practices. Subjective norms had a strong influence on intention to engage in landscape water conservation, and past behaviors and personal norms improved the prediction. Extension professionals should incorporate subjective norms into water conservation programs by emphasizing somewhat invisible conservation behaviors to improve perceptions of peers' practices. When personal norms are strong, the subjective norms are slightly less important. Residents who feel a personal obligation to conserve water may be more open to information related to water conservation, and they may be more likely to act, even in the absence of social support. Finally, Extension professionals should consider the audience's past behaviors to design programs that are compatible with actions that Extension clients are likely to take.

Large amounts of water applied as urban irrigation can often be reduced substantially without compromising esthetics. Thus, encouraging the adoption of water-saving technologies and practices is critical to preserving water resources, yet difficult to achieve. The research problem addressed in this study is the lack of characterization of residents who use urban irrigation, which hinders the design of effective behavior change programs. This study examined audience segmentation as an approach to encouraging change using current residential landscape practices. K-means cluster analysis identified three meaningful subgroups among residential landscape irrigation users (N = 1,063): the water considerate majority (n = 479, 45 %), water savvy conservationists (n = 378, 36 %), and unconcerned water users (n = 201, 19 %). An important finding was that normative beliefs, attitudes, and perceived behavioral control characteristics of the subgroups were significantly different with large and medium practical effect sizes. Future water conservation behaviors and perceived importance of water resources were also significantly different among subgroups. The water considerate majority demonstrated capacity to conserve, placed high value on water, and were likely to engage in behavior changes. This article contributes to the literature on individuals who use residential landscape irrigation, an important target audience with potential to conserve water through sustainable irrigation practices and technologies. Findings confirm applicability of the capacity to conserve water to audience segmentation and extend this concept by incorporating perceived value of water resources and likelihood of conservation. The results suggest practical application to promoting residential landscape water conservation behaviors based on important audience characteristics.

Today's complex issues require technical expertise as well as the application of innovative social science techniques within Extension contexts. Researchers have suggested that a social science approach will play a critical role in water conservation, and people who use home landscape irrigation comprise a critical target audience for agriculture and natural resources professionals. This study was conducted to examine the possible role of an audience segmentation approach in addressing the complex issue of water resources. This research used descriptive discriminant analysis to assign national irrigation users to previously identified subgroups found in the literature (the water considerate majority, the water savvy conservationists, and the unconcerned water users) and compare characteristics to identify differences on a national scale. Results revealed the nation's irrigation users are fairly water conscious. The findings implied unique subgroups exist among targeted Extension audiences relevant to specific behaviors, and Extension programs should focus on different programmatic objectives for targeting different subgroups. Differences were found among the three subgroups in water conservation behaviors, personal and social normative beliefs, use of landscape professionals for irrigation maintenance, and learning preferences. Recommendations were provided on how to use the results to develop impact-driven Extension programs.

Changing individuals' behaviors is a critical challenge for Extension professionals who encourage good irrigation practices and technologies for landscape water conservation. Multiple messages were used to influence two predictors of behavioral intent informed by the theory of planned behavior, Florida residents' (N = 1,063) attitude and perceived behavioral control. Individuals were randomly assigned to one of four treatment groups, each receiving a different strategically framed message. This article contributes to the literature on landscape water consumption behaviors by (a) demonstrating that messages can be used to positively affect both attitude and perceived behavioral control and (b) identifying specific message frames that may be used to realize greater impact. Two gain-framed message treatments both significantly increased participants' attitude and perceived behavioral control, and one of the loss-framed messages significantly increased participants' attitude. Results are discussed with practical application to promotion of landscape water-conservation behaviors and implications for future research.

Agricultural educators, leaders, communicators, and extension professionals are faced with the increasingly difficult task of sharing science-based information to a public that is exposed to an array of media options, which are not always factual. Additionally, issues related to agriculture and natural resources (ANR) have become increasingly complex, and people can elect to only read information or communication that supports their pre-existing views on a topic. The complexity of disseminating information in today's society has led to the proposal of a new theoretical model: The Decision-Making Model for ANR Science and Technology. This is a multi-facetted model utilizing the theoretical foundations from the Theory of Diffusion of Innovations, Theory of the Spiral of Silence, and the Elaboration Likelihood Model. In a world of echo chambers, this theory has the potential to break the cycle of decisions made with incomplete information and equip practitioners with the foundation needed to efficiently and effectively disseminate information through educational practice and informed communication efforts. An informed and aware public could make decisions about ANR science and technology with a more complete understanding of the issue, which would solve some of the wicked problems facing society today.

Water quantity and quality are among the top issues currently facing Florida. To understand residents' perceptions of these issues as well as understand how agenda-setting may be used to influence residents' behaviors and opinions surrounding water issues, this study explored Florida residents' opinions of water. Agenda-setting served as the conceptual framework to aid in understanding where water quality and quantity emerge on the public's agenda. Responses were obtained from 469 Florida residents via an online survey. The results showed respondents believed water quality had not changed, with the exception of the quality of bays, which they believed was getting worse. Water quality was found to be an issue of high importance among respondents, especially in regard to the quality of drinking water. Respondents believed water quantity was highly important; however, more importance was associated with water quality issues. The results of this study identified the current disconnect that exists among residents concerning water issues. This study also established the salience of water issues on the public's agenda and how Florida residents could be better informed. A statewide communication campaign focused on both water quality and quantity issues was recommended to decrease the disconnect that currently exists between residents' perceptions and the reality of water issues. This campaign should utilize the technology-based outlets to stay informed with the public's agenda to personalize communication efforts. These efforts would increase the public's interest concerning water issues by reducing redundant information and diluting important issues.
