Abstract: Water policy is an important topic on the agenda of the international community, and efficiency and equity in the allocation of water have emerged as important factors to be considered. Water pricing can be used to mitigate both the quantity and quality dimensions of water scarcity. This paper reviews partial equilibrium models and general equilibrium models that are relevant to irrigation water management issues. The most widely discussed issues in these models are water markets and water pricing. The interrelationships between economic, cultural, social, and political aspects that are related to water policy make it difficult to provide a comprehensive policy analysis. General equilibrium models of irrigation water management allow incorporation of both the irrigation sector and the other sectors in the economy and analysis of policies affecting each of them and the interaction between them. In addition to being able to address sector and household specifications, production factors, time horizon, pricing policies, and institutions such as water markets, general equilibrium models allow the analysis of the impact of water policies on equity and poverty alleviation. The authors conclude that, although there has been a significant increase in efforts to analyzewater related problems, analytical and empirical research in the field is still deficient and more effort is needed to address them.
