This study provides an empirical perspective on alternative irrigation policies for allocating limited water to agricultural production in Egypt. Positive mathematical programming is used for model calibration. Three policy options for Egypt are tested: water pricing, water complementary input factor taxes, and output taxes. The results of the research show that: 1) water pricing needs to be much higher than the recovery cost in order to be effective in limiting irrigation water use; 2) at a higher tax rate, fertilizer and energy taxes are effective in reducing the irrigation water demand while maintaining adequate welfare levels; 3) a pesticide tax is less effective than fertilizer or energy taxes; and 4) an output tax on sugar cane and rice would... |

This paper uses an agricultural sector model to evaluate the effects of an ambitious and ongoing policy reform program on agricultural production and resource use in Egypt. The results show that Egypt has already gained from the policy reforms, but that much larger gains depend on increased exports of high value crops. Water is found to be emerging as an important constraint on agriculture, and it will be essential to establish more effective institutional and pricing mechanisms to encourage greater water use efficiency in the future. Because many of the new lands compete with the more productive lands of the Nile delta for water, the economic return to the development of new lands is also found to be low. The policy reforms are not likely to lead to... |

For a number of reasons government the world over have been unwilling to use water pricing to achieve water use efficiency. This research addresses questions of what policy alternatives to water pricing might improve irrigation water allocation efficiency. An empirical framework is provided to compare irrigation policies for allocating scarce water to agricultural production in Egypt and Morocco. Partial equilibrium agricultural sector models specific to Egypt and Morocco were employed for policy tests. Positive Mathematical Programming (PMP) was used to calibrate the models. Water pricing policy, water complementary input factor tax policy, and output tax policy are tested. Results suggest that effective policy depends on the social, economic, and... |
