Abstract
Three types of interventions have been implemented to promote water conservation behaviours: feedback, social norms, and sensitivity campaigns. The aim of this review is to assess methodological aspects and to estimate the efficacy of these interventions. We selected 31 articles through a systematic literature search. For each strategy, we analysed 6 essential methodological variables and we calculated the average effect size. We found a noticeable lack of control group and pre-post measures. The effect size was medium in feedback interventions and small in social norms and sensitivity interventions. Feedback strategies reported better methodological conditions. However, it is necessary to improve these essential methodological aspects and to report statistics which allow a more reliable estimation of efficacy. Despite this, there is a positive tendency of the three strategies, with feedback interventions having a greater effect.
