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.

The present study aims to identify and prioritize agricultural water protection Solutions in Kermanshah province with a Delphi-fuzzy. As a paradigm the research was qualitative and exploratory approach. The research was done approach in two rounds to reach a group agreement between 25 experts. The results showed that water conservation Solutions can be classified into four categories: "managerial", "technical", "cultural", "infrastructure" and "policy-making". In two rounds DE fuzzy variance was less than 0.25, so all identified strategies were valid.The results also showed that the most important strategies in each of the strategies are the strategies of changing the cultivation pattern, equipping farms with a new irrigation system, creating a culture by the media and reviewing the rules and regulations of the water sector. Agricultural production is significantly affected by the state of water resources as well as the policies of the responsible inputs. Agricultural production is significantly affected by the state of water resources as well as the policies of the responsible institutions. If the water crisis is not dealt with, in addition to a significant reduction in agricultural production and economic decline in the province due to the centrality of agriculture, it will lead to a reduction in rural incomes. Agricultural production is significantly affected by the state of water resources as well as the policies of the responsible inputs. Agricultural production is significantly affected by the state of water resources as well as the policies of the responsible institutions.

Recognizing the moral norms is necessary to understand water crisis and have water protection behavior in today’s society. The aim of this research was to develop the theory of planned behavior and quantification of its components in order to assess the moral norms governing the participatory management of water resources. A questionnaire was used to collect information from Toshan and Galand villages. Descriptive-inferential statistics of the research were analyzed by SPSS and SmartPLS softwares and One-Sample Wilcoxon Nonparametric test. Then model components were ranked using Friedman test. At the end, the uncertainties of the components of the Modified Theory of Planned Behavior (MTPB) were calculated by the bootstrap technique. The results showed that adding the moral norm component to the theory is important for promoting participatory behaviors of water conservation. According to the boxplot graphs and model path coefficients, most respondents had a high moral commitment to participate in water conservation, which shows that they consider themselves responsible for local water resources. Also, the level of social acceptance of the respondents to the policy option of participatory exploitation of water resources was above the middle level and uncertainty band of social acceptance for the research components indicated the intra-level coordination towards the adoption of the policy option of participatory exploitation of water. The results of the structural model showed that the MTPB variables, respectively, explain 70.1%, 75.9%, 81% and 79.2% of the variance of the participatory behaviors of water conservation of stakeholders of Toshan drinking, Galand drinking, Toshan agriculture and Galand agriculture.

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.
