Land drainage is becoming increasingly important owing to continued irrigation and because less promising soils were cultivated. This particularly in areas with potentially saline groundwater, facilitating salt accumulation in many irrigated soils. The water and salt balance in the top soil has become more complicated with the growing shortage of irrigation water in most arid countries and the pollution of water in their rivers. Therefore, there is a marked tendency to investment in improved performance of irrigation and drainage systems.
