About 2 million ha of the total 4.3 million ha of irrigated land in Uzbekistan have subsurface drainage systems. The total length of this drainage network exceeds 40,000 km. Almost half of the network requires rehabilitation because of overage materials and poor maintenance. The rate at which drainage systems are being rehabilitated should be increased significantly to prevent the loss of soil fertility due to salinisation.
