Investigating The Effective Factors On Household Water Demand in Iran:A Systematic Review and Meta-Analysis

One of the most effective tools for water demand management is the recognition of price and income elasticity for water demand. In this study, using systematic review and meta-analysis, the factors affecting the price and income elasticity of household water demand in Iran have been investigated. Accordingly, first, using Rosenthal and Robin's approach in systematic review, the effects of price and income elasticities of household water demand have been calculated. Then, based on the heterogeneity between the calculated effects of the effects size, random and fixed effects models are used to combine the results. Finally, according to the results, the variables related to the water demand profile, the survey data, the water price, the water pricing structure, the model, the estimation method, the study area and other characteristics of the study, the estimated values of Prices and income elasticity for household water demand have been effective, so water demand management policies should be based on these characteristics.
