The Gezira irrigation scheme in Sudan : objectives, design, and performance (English)

This report is part of a series of case studies on the performance of irrigation systems in different countries. These studies focus on the extent to which the design of the irrigation system fosters effective water management and provides equitable, reliable, timely water distribution to farms (by analyzing water efficiencies, the effectiveness of maintenance, and cost recovery). The report recommends the design of the physical infrastructure, and states the impact on the management of these systems. Because of the comparative nature of this study, this report on the Gezira scheme in Sudan makes only passing references to some specific but critical aspects of this project, such as the capacity of the system to adapt to changing socio-economic conditions.
