Empirical Analysis of the Demand for Water by Israeli Agriculture,s the thesis—basic to the approach—that in the economic analysis of the complex of problems of the water resource in agriculture, irrigation water can and should be referred to as any other production factor which takes part in the process of agricultural production. Concerning the demand for irriga

A Model for the Economic Evaluation of Water Quality in Irrigation, The response may arise from a high total concentration of salts (osmotic effects), a relatively high concentration of a specific ion, or a combination of the two. The specific effect of an ion may be one of direct toxicity or of nutrition. Depending on the nature of the particular plant and given c

Optimal Allocation of Farm Irrigation Water During Peak Seasons,y true during peak seasons of demand for irrigation water. Water allocation among competing farm uses has been treated in numerous linear programming studies (Yaron). However the early linear programming (LP) studies have incorporated crop response functions to irrigation and soil moisture only indi

The Value of Information on the Response Function of Crops to Soil Salinity, process. The knowledge of the biological response function of crop yield to soil salinity is essential in decision-making regarding irrigation with saline water. In this paper we investigate (analytically and empirically) the expected profitability to farmers (the decision makers) of acquiring addi

A Model for the Analysis of Seasonal Aspects of Water Quality Control,lems of water quality management in river basins. Although the ideal formulation of such problems is to maximize net benefits from pollution abatement, because these benefits are hard to quantify, a second-best approach has been to minimize the social cost of achieving predetermined quality standard
