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.

This article concentrates upon the growing problem of soil waterlogging and salinity caused mainly from the lack of drainage and which threatens to destroy the food-producing capacity of the world's irrigated lands. Briefly summarizes the causes of drainage problems and the recent acceleration of such problems. Reviews some of the technical alternatives for irrigated land drainage and their economic implications. Concludes that there is still a great level of ignorance of the technical, financial, econometric, social, political, legal, and administrative aspects of drainage making it a fertile field for basic and applied research. Illustrated with several examples from Pakistan and Egypt.

(Location: IWMI-HQ Call no: P 1414 Record No: H01002)
Efficiency in the use of water for irrigation is normally defined in a physical sense - engineering and agronomic; and it is often assumed that higher efficiency is desirable. However, an economic sense, there is an optimum range in the level of physical efficiency. It can be said that as water prices increase, it becomes more rational to increase physical efficiency by selecting and adopting improved methods of controlling, measuring and applying water, and to design systems of pricing and regulations that will promote optimal allocation and efficient use. However, the value of water is often low, in which case there may be little economic incentive to improve physical efficiency unless forced by physical factors that affect production and productivity such as soil characteristics, water logging or nutrient leaching. The combination of regulations and prices that are used to allocate irrigation water reflect the conflicting goals of redistribution of income in favour of agriculture and needs to encourage efficient use of water, the dependability of supplies, systems of delivery and the extent to which flows can be regulated. Using examples in case studies, this paper discusses physical and economic efficiencies and their interrelationships. It emphasizes the role of pricing and regulations and provides general guidelines.

Reprinted with permission from Lands at Risk in the Third World: Local Level Perspectives, edited by Peter D. Little and Michael M. Horowitz, Boulder, CO, Westview Press, 1986. The paper analyzes changes in local resource management strategies and the environmental impact of centralized irrigation management in the Indus Basin since the mid-19th century. These changes are viewed primarily as responses to increasing interventions of the state, and the co-opting through centralization of what had been local functions by higher level bodies. This in turn has led to an inability to respond to local level problems before they reach crisis proportions. To interpret the trends and identify key problems and issues, the paper draws upon a systems theory model of the evolution of the state that was originally developed by scholars interested in the demise of Mesopotamian civilization. The analysis provides the basis for a short critique of present development programs and for identifying several key research questions.
