Abstract
The efficient use of water resources where ground water and surface water are used conjunctively may require special policies to rationalize the interaction among pumping by farmers, canal diversions by irrigation system managers, and the physical response of the stream aquifer system. The problem is acute in the great alluvial basins of Asia the Indus, Gangetic, and North China Plains Where surface water irrigation has long been practiced and modern tubewell technology has been diffused extensively in recent decades. These alluvial basins account for a large proportion of total irrigated land in developing countries and the countries involved account for about the half of the world's population. Significant gains in output are possible from more efficient conjunctive use in such regions (for example, an increase of 20 percent is estimated for Pakistan). However, these potential gains are not costless because their realization requires changes in irrigation institutions, methods of irrigation management, and often accompanying investment in drainage facilities
