s for the costs they impose on the water supply systems, many of them still promote irrigation projects, seek market protection for certain crops, and establish generous grandfathering provisions for irrigators’ obligation to pay higher water rates (OECD, 1999; Garrido, 1998; Dinar and Subramanian, 1997).
