1 O'Mara, G. T. 1984. Issues in the efficient use of surface and groundwater in irrigation. Washington, DC, USA: World Bank. [20], 93 p. (World Bank staff working paper no. 707)
(Location: IWMI-India Call no: 631.7.6.3 G000 OMA Record No: H0493)
The efficient use of water resources where groundwater 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 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% 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 investments in drainage facilities. Three broad approaches to the problem of efficient resource use under externalities (that is, physical interdependence among individual producers) have been defined by economists: (1) assignment of well- defined, transferrable property rights; (2) imposition of corrective taxes or subsidies; and (3) centralized control over the entire resource. The feasibility and institutional implications of these approaches are discussed and several case histories of actual policy responses to the social costs incurred by inefficient conjunctive use are reviewed. The use of more sophisticated analytical methods in coping with the difficult informational and managerial requirements of efficient conjunctive use will require much better information systems, more skilled and responsive irrigation managers, and institutional reform that involves water-using farmers more actively.

Drainage, groundwater withdrawals and altered irrigation practices are among the techniques for reducing waterlogging problems resulting from inefficient water use. However, these corrective measures are often not adopted since the private costs incurred by the individual operator quite often exceed the private benefits. Net social benefits are likely to be positive, so collective action may be appropriate. The overall objective of this paper is to develop an integrated approach combining both economic and physical considerations in order to evaluate possible collective alternative approaches to relieving waterlogging problems. Using survey data from the San Luis Valley, this paper presents a recursive linear programming model that includes both uncertainty and capital constraints. This model incorporates a weekly short-run water allocation model and a simplified water balance model of the groundwater to form a complete simulation model. The model was run using 20 years of historical climatological data to represent the long-run effects of policies which might be undertaken by the water users or by the Colorado State Engineer. Policy alternatives modeled include: Investment in canal lining, total conversion to sprinkler irrigation, various restrictions on groundwater pumpage, and a modified quota-market system. A comparison of the economic and physical results of these simulated alternatives is made and policy recommendations are suggested.
