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.
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.
Nursery and greenhouse operations require significantly large amounts of water to maintain product quality and often use more than what is needed by the crop being grown. The nursery industry’s use of water is highly criticized and adds to arguments against agricultural water use with increasingly limited water resources available globally. The purpose of this study was to explore the barriers and motivators associated with nursery and greenhouse growers’ adoption of water conservation and treatment technologies. In-depth interviews were conducted with 24 operators across the U.S. to identify their perceptions of new water-saving technologies and treatments based on the five attributes of an innovation identified by Rogers (2003). The findings revealed growers are aware of water-saving technologies and the rate of adoption depends on a variety of factors including: perceived cost, lack of ability of their workforce to use the new technology due to its complexity, and belief that their product will be worth more if it is grown in an environmentally-friendly manner. Barriers to adoption included the high cost of replacing equipment, incompatibility with existing systems, and the perception that new technologies do not fit in with the traditional hands-on approach to horticulture. Suggested extension programs to reach growers include developing materials that highlight the economic benefit of adoption and cost recovery, YouTube videos that reduce issues with perceived complexity growers can use with their workers, and programs that emphasize how technology fits in with the culture of the horticulture industry.
Nursery growers are one of the largest agricultural users of water. Researchers have been developing new water treatment techniques and technologies for nursery growers to assist in preserving this precious resource, yet adoption within the industry has been limited. Extension professionals need to work closely with nursery growers to encourage adoption but the enablers and barriers are largely unidentified in the literature. Twenty-four interviews were conducted with nursery growers nationwide to identify the barriers and enablers to adoption in an effort to provide recommendations for improved extension programming with this audience. The findings revealed nursery growers have a positive attitude towards water conservation but the financial cost of replacing equipment keeps them from adopting. In addition, nursery growers perceive new technologies to be complex and difficult to understand and implement. Extension professionals can leverage this positive attitude and use social norms to assist in overcoming some of the barriers. Using case studies as examples of success stories, partnering with researchers to develop easy to use instructions and integration tools that could be offered online, and assisting growers in connecting with agricultural economists to conduct cost/benefit analysis associated with adoption are a few of the recommendations offered.
