A Comparative Analysis of Behavioral Theories towards Farmers’ Water Conservation

According to experts, the inefficient agricultural sector has a dominant role in degrading water resources all over the world. Farmers’ conservational behavior is an important aspect of new integrated water management studies. Relevantly, various behavioral theories have been proposed in the field of environmental psychology. The main objective of the present comparative analysis and review study was to explain foundations of the most remarkable water conservation behavioral theories, classify them, and finally, present a critical discussion on the better application of each theory to explain the farmers' Water Conservation Behaviors (WCBs). This study is based on the documentary research method which was accomplished using a systematic literature review. The comparison analysis of existing theories indicates that the “theory selection” should be consistent with the “type of behavior under study”. Consequently, it is recommended to adopt the theories like Planned Behavior Theory and Reasoned Action Theory to illustrate the private-sphere WCBs such as farmers’ willingness to pay for water conservation because these behaviors are directly associated with the farmers’ personal interests. With respect to those conservational behaviors with participatory and collective nature, an individual may ignore his/her short-sighted and immediate benefits to achieve collective and long-term interests. In such a case, the use of moral approach and its relevant theories, including the Value-Belief-Norms Theory and the Norm Activation Theory, seems to be more appropriate. Consequently, agricultural practitioners and researchers are recommended to use rational approach theories to analyze the WCBs of farmers.
