The activity was task managed by Safwat Abdel-Dayem, drainage advisor (ARD), and coordinated by Peter Mollinga, associate professor, Wageningen University. This country study is one of six parallel studies. The other studies are on Bangladesh, Egypt, Mexico, the Netherlands, and Pakistan. Together they provide the basis for formulating the proposed approach. The task manager and the coordinator provided general direction for the study and contributed comments on preliminary texts. The country study benefited from the critical comments provided during the workshop held in Wageningen, the Netherlands, October 23–25, 2002, and attended by Bank staff, country officials, and representatives of International organizations,
