Encouraging households to adopt residential water conservation behaviors, as an efficient strategy for sustainable water supply, has caught the attention of water demand management. However, the success of such policies depends on the voluntary acceptance of these measures by urban households. Considering the important role of psychology in explaining human behavior, the present research explored the key socio-psychological factors underlying the household adoption of WCBs and how these behaviors can be explained by expanding the theory of planned behavior via adding the habit variable to the TPB’s main model. In the current study, which focuses solely on water curtailment behaviors (behavioral conservation), 343 Isfahan citizens participated. In this regard, a cross-sectional survey was conducted using a structured questionnaire, as a research instrument, and the structural equation modeling method was also applied for data analysis. The results revealed that, by adding the habit variable to the TPB's main model, the extended model can predict 75% and 51% in the variance of intention to adopt water curtailment behaviors and water curtailment behaviors, respectively. Based on the findings, the attitude and perceived behavioral control variables had a significant positive relationship with intention, whereby attitude had the most predictive power of intention to adopt water curtailment behaviors. Moreover, the habit and intention variables were significantly and positively related to water curtailment behaviors, of which habit was the most important determinant of behavior. However, subjective norm had no significant relationship with intention, and perceived behavioral control was not significantly related to behavior. Finally, policymakers are advised to develop and implement awareness-raising and education campaigns aimed at (1) creating positive attitude toward WCBs among urban households, (2) increasing their self-efficacy and self-confidence in performing these actions, and (3) improving and/or changing their water conservation habits in order to improve WCBs among urban households.

Ensuring water security in the face of population growth and resource scarcity has posed a serious challenge for policymakers in urban areas and led them to water demand management (WDM) approaches. Water conservation as a key factor in WDM is an effective solution to the sustainable urban water supply that includes two categories: water curtailment behaviors and water-efficiency behaviors. Given that the voluntary acceptance of water conservation behaviors by individuals, understanding the psychological determinant processes of these behaviors is an important aspect in designing effective policies and interventions in this area. Therefore, the purpose of this study was to investigate factors affecting water conservation intentions and behaviors among Tehran citizens using the theory of planned behavior (TPB). The data collected using both online and offline surveys (N=820) in Tehran by a structured questionnaire, which its validity was confirmed by experts, and its reliability was confirmed by Cronbach's alpha coefficient. Data analyze conducted through the structural equation modeling. Based on the results, the TPB can explain 83% and 40% of the variance in water curtailment intentions and behaviors, respectively, and 57% and 37% of the variance in water-efficiency intentions and behaviors, respectively. The results also suggested attitude and perceived behavioral control affect the intention regarding both behaviors, but subjective norm does not affect the intention for both behaviors. In addition, the results revealed that both behaviors influenced by intentions and perceived behavioral control. Finally, based on the results, implications for improving residential water conservation and suggestions for future research are provided.

Noticing drought crisis in Iran and importance of water conservation and recognizing its determinants, this research attempted to study the applicability of the theory of planned behavior variables in predicting water conservation behaviors among college students. Survey method was used for this research and questionnaires were distributed among 122 female college students resided in dormitories of Yazd University. Finally, collected data were analysed by SSPS statistical method. The results indicated that behavioral intention and perceived behavioral control variables were able to predict 44% of variance in water conservation practices among participants. Also, two structures of subjective norms and perceived behavioral control explained 34% of variance in behavioral intention for water conservation among participants. College students who had more intention for water conservation and believed to have more control over their behavior for water conservation, behaved better in conserving water accordingly
