Making the case for integrated water resources management: Drainage in Egypt
For a long time, water resources management in Egypt was concerned mainly with quantitative water management and with salinity control in order to sustain the productivity of irrigated agriculture. The drainage program was closely linked to the irrigation program and was primarily planned as a measure to safeguard crop productivity levels.
An evaluation of the drainage program in the old lands (i.e. the Nile Valley and Delta) suggests that the drainage program in Egypt managed to achieve this objective and provided the basis for significant increases in agricultural productivity. At the same time, drainage helped to improve – almost by stealth ‐ the human living environment through lowered incidence of waterborne diseases, improved sanitation, and reduced damage to property. Yet as the intensity of water uses increases in Egypt, the interlinkage and interdependency between the different water uses is growing exponentially. Drainage plays a crucial role in these interlinkages, particularly through the reuse policy and practice, which raises important issues on water quality throughout the system. In Egypt, drainage is a pivot in integrated water resources management because of the effects of drainage effluents on aquatic ecology, particularly in the northern estuaries. This paper argues that objectives in the field of water quality and ecology should get a far more central place in drainage management and water resources management, in general, in Egypt. This paper makes the case for integrated water resource management and, in particular, attempts to look at drainage from an integrated perspective. It reviews the contribution of drainage to water reuse, to water quality management and the effect on fish production in productive northern estuaries. Finally, measures in water governance and in the planning of drainage infrastructure are recommended.
