The main objective of this study is to estimate the expected value of stochastic irrigation water deliveries under trading water rights conditions that may introduce irrigation water shortages. Thus, farmers are faced with added uncertainty in conjunction with other risk sources manifested in output price, spring soil moisture, and precipitation. Risk components of the demand for irrigation water must be identified in order to estimate the water values.

520 $a The main objective of this study is to estimate the expected value of stochastic irrigation water deliveries under trading water rights conditions that may introduce irrigation water shortages. Thus, farmers are faced with added uncertainty in conjunction with other risk sources manifested in output price, spring soil moisture, and precipitation. Risk components of the demand for irrigation water must be identified in order to estimate the water values.
520 $a A discrete sequential stochastic programming model is developed and the flow of information is assumed to follow a complete knowledge of the past and present structure. Estimates of the value of stochastic water deliveries resulting from water transfers are obtained through subtracting the values of risk penalties from the deterministic value of water. In addition, an estimate of the risk aversion parameter that captures the decision makers' preferences toward risk is obtained. A sample of twelve farms representing the production-farming units located at the Eastern Irrigation District in southern Alberta is fitted to the empirical models.
520 $a The risk aversion parameter estimate that describes the preference of southern Alberta's producers of irrigated crops toward risk is 0.00002, which can be described as mildly risk averse, since the estimated coefficient is positive and relatively close to being risk neutral. The linear non-stochastic model valued water between $4 7/ha-cm ( $5 76/ac-ft) and $1 32/ha-cm ( $1 632/ac-ft). The values of risk penalties, for five scenarios of irrigation water availability ranging from zero to 100 percent, ranged from $4 1/ha-cm ( $5 03/ac-ft) for the first 5 to 25 percent of irrigation water deliveries to $1 1/ha-cm ( $1 33/ac-ft) for the remaining 30 to 95 percent of irrigation water deliveries.
520 $a The estimates of the marginal value of stochastic irrigation water deliveries reach $1 28 per ha-cm ( $1 579/ac-ft) when irrigation water is scarce, compared to $3 8 per ha-cm ( $4 67/ac-ft) when water is abundantly available. When potato hectares were constrained, the deterministic value of water was $1 9.80 per ha-cm ( $2 44.33 per ac-ft) and the value of stochastic irrigation water deliveries declined to $1 2.39 per ha-cm ( $1 52.81 per ac-ft).
