“…A value of$150 per acre-foot was used, based on Stroh (1990) and adjusted to 1987 price level, for drainage treatment costs in the case of no river disposal (Strategy III). The additional cost associated with reuse was assumed to be $15 per acre foot after Knapp, Dinar, and Letey (1986), and adjusted for inflation since 1987. Where pd was taken to be = 0 for Strategies I and II where farmers are not restricted with the disposal ofthe drainage water.…”

This chapter provides conceptual arguments and empirical evidence to show that the blending approach typically used for water quality protection can result in economic losses to the agricultural community as a whole. A better strategy is suggested for dealing with the "disposal" of saline agricultural drainage waters which provides greater practical benefit to be derived from the total water supply than blending does. In this strategy the drainage water is intercepted, isolated from the good-quality water, and reused for the irrigation of suitably salt-tolerant crops in the same project. Ultimately, a greatly reduced volume of secondary drainage water is disposed of or treated in some manner other than blending.

The use of saline drainage water for irrigation is a management practice that results in fresh water savings and also addresses the problem of drainage water disposal. However, environmental and economic restrictions need to be considered in order to design a sustainable system. An optimisation routine is proposed here that aims to estimate the quantities of drainage water that could be used for irrigation. The proposed routine incorporates crop–water production functions to simulate a crop's performance under a saline environment. The area of implementation was the regional irrigation network of Agoulinitsa in western Greece, a coastal region with a shallow aquifer. Scenarios under different prices of fresh water and salinity values of drainage water were examined.

“…Perhaps the first to analyze the efficacy of mixing waters were Parkinson et al [1970]; however, they considered only predetermined blending combinations. For Feinerman and Yaron [1983] and Knapp and Dinar [1984] blending was endogenous and, depending on prices and crops' salinity tolerance, could become optimal at the regional and field levels, respectively. However, in both of those studies, salinity was the only factor affecting production.…”

[1] Blending fresh and saline irrigation waters is implemented in many countries facing water scarcity. However, when analyzed at the field level, previous economic studies have indicated that blending fresh and saline water is suboptimal. This paper examines the blending issue on a regional scale, where both water sources and land are concurrently allocated to crops. Regional water distribution networks that enable salinity adjustment at the field level are compared to networks that allow controlling water salinity on a regional scale only, such that salt concentrations cannot differ by crop. We characterize the conditions for blending to be an optimal strategy under regional salinity control networks, and show that these conditions can be met by an empirical water production model commonly used in the literature. Empirical analysis of 16 regions in Israel revealed optimal blending in six of them. However, regardless of whether blending is optimal or not, the optimal fresh-water application is higher under regional salinity control networks, implying that blending does not support freshwater conservation. The paper analyzes the relationship between water and land constraints' shadow values, and the properties of the two water distribution networks. We show that although farming revenues are higher under networks that allow assignment of specific water salinities to crops, regional salinity control networks can become more profitable to farmers who face prices set endogenously so as to be the binding factor on the use of constrained water and land. The implications of the network selection on intraregional water supply costs are discussed.Citation: Kan, I., and M.
