"WATER SCARCITY AND WORLD TRADE: A COMPUTABLE GENERAL EQUILIBRIUM APPROACH"
by Rehdanz, Katrin, Maria Berrittella, Roberto Roson and Richard Tol


Abstract
Water problems are typically defined and studied at the level of the river catchment. Yet, 80% of all water is used for agriculture, and agricultural products are traded internationally. A complete understanding of water use is therefore impossible without understanding the international markets for food and other agricultural products, such as textiles. The water embedded in commodities is also called virtual water.
Based on a general equilibrium model this study offers a method for investigating the role of water resources and water scarcity in the context of international trade by analysing virtual water flows. We run four alternative scenarios, some with variants. The first three scenarios are directly concerned with water resource policies. The first two scenarios are quantity scenarios. The third is a water pricing scenario. In the fourth scenario we consider a trade liberalization reform in the agricultural sector. Unlike the first three scenarios, the latter deals with trade policy in water-intensive industries.
