AN ECONOMIC EVALUATION OF THE COLORADO RIVER BASIN SALINITY CONTROL PROGRAM AgEcon
Gardner, Richard L.; Young, Robert A..
Dissolved salts (salinity) adversely affect numerous urban and agricultural users of Colorado River water in California and Arizona. Congress in 1974 authorized a major salinity control program. Studies of general economic benefits from salinity abatement and the cost per unit of salinity reduction expected from specific proposed projects have been developed by the responsible federal agencies, but no project-by-project evaluation has been published. We find a conceptual basis for a substantial downward revision of prospective economic benefits of salinity abatement. Revised benefits are compared with estimated costs, and only for five of the nineteen projects do economic benefits appear to exceed costs.

Derivation of supply curves for catchment water effluents meeting specific salinity concentration targets in 2050: linking farm and catchment level models or “Footprints on future salt / water planes” AgEcon
Nordblom, Thomas L.; Bathgate, Andrew D.; Young, Robert A..
The salt burden in a stream reflects the blend of salty and fresh flows from different soil areas in its catchment. Depending not only on long-run rainfall, water yields from a soil are also determined by land cover: lowest if the area is forested and greatest if cleared. Water yields under agro-forestry, lucerne pasture, perennial grass pasture, and annual pasture or cropping options span the range of water yields between the extremes of forested and cleared lands. This study explores quantitative approaches for connecting the hydrologic and economic consequences of farm-level decisions on land cover (productive land uses) to the costs of attaining different catchment level targets of water volumes and salt reaching downstream users; environmental,...

Determining the Price-Responsiveness of Demands for Irrigation Water Deliveries versus Consumptive Use AgEcon
Scheierling, Susanne M.; Young, Robert A.; Cardon, Grant E..
A water-crop simulation/mathematical programming model of irrigation water demand in northeastern Colorado is formulated to develop an original concept of derived demand for consumptive use of water. Conventional demand functions for water deliveries are also developed, and the effect of hypothetical price increases on both consumption and delivery are illustrated. Findings indicate that demand elasticity estimates are quite sensitive to model specification, and consumptive use demand tends to be significantly less price-responsive than delivery demand. Thus price incentives are likely to have only limited impacts on basin-wide water consumption and would not make much additional water available for emerging demands.

IRRIGATION WATER DEMAND: A META ANALYSIS OF PRICE ELASTICITIES AgEcon
Scheierling, Susanne M.; Loomis, John B.; Young, Robert A..
Meta-regression models are estimated to investigate sources of variation in empirical estimates of the price elasticity of irrigation water demand. Elasticity estimates are drawn from mathematical programming, econometric and field experiment studies reported in the United States since 1963. Explanatory variables include method of analysis, water price, time-frame of analysis, farmers'’ adjustment options, type of data, and climate. Results indicate that the magnitudes of elasticity estimates are affected by the method of analysis. When separate regressions are performed for the estimates from each method, the price of water at which an elasticity is estimated as well as the time-frame of analysis are found to influence price elasticities.

OPTIMAL TEMPORAL AND SPATIAL SCHEDULING OF ARID-REGION WATER SUPPLY PROJECTS WITH NONRENEWABLE GROUNDWATER STOCKS AgEcon
Booker, James F.; Taylor, R. Garth; Young, Robert A..
Faced with explosive population and business growth, arid-area cities such as Las Vegas, Nevada, are scheduling water supply projects far into the next century. The city now relies on Nevada's small share of the Colorado River and meager local renewable water supplies. Substantial deposits of ground water of adequate quality located at some distance from the population center are a possible supply option. This paper develops a model for analyzing the economic feasibility and the optimal investment path for water supply for Las Vegas. We forecasted residential, industrial, and other municipal demands and the schedule of increasing costs of the water supply options. A dynamic programming model determines the optimal groundwater pumping projects in...

PRICE-RESPONSIVENESS OF DEMAND FOR IRRIGATION WATER WITHDRAWALS VS. CONSUMPTIVE USE: ESTIMATES AND POLICY IMPLICATIONS AgEcon
Young, Robert A.; Cardon, Grant E.; Scheierling, Susanne M..
Of water withdrawn for agricultural crop irrigation, a portion is consumed and the remainder comes back to the hydrologic system as return flows. Previous models of irrigation water demand have mostly focused on the change in withdrawals in response to price changes, even though knowledge of the response of consumptive use is often more significant for river basin planning. This study develops a simulation/mathematical programming model of water demand representing an irrigation company in northeastern Colorado to analyze the effect of hypothetical price increases on both the demand for withdrawals and a derived demand for consumptive use. The results demonstrate that consumptive use demand tends to be significantly less price-responsive than withdrawal...

RURAL-TO-URBAN WATER TRANSFERS: MEASURING DIRECT FOREGONE BENEFITS OF IRRIGATION WATER UNDER UNCERTAIN WATER SUPPLIES AgEcon
Taylor, R. Garth; Young, Robert A..
Irrigation water from a southeastern Colorado county has been sold to distant municipalities. The county's junior water right delivered limited and uncertain water supplies which were used on relatively poor soils. The ability of water markets to allocate water to the highest-valued use was addressed by assessing the direct foregone benefits of the transfer using deterministic and discrete stochastic sequential (DSSP) programming models. Crop mix predicted by the DSSP followed observed regional patterns. The DSSP was thus used to derive regional water demand from which foregone value was estimated. Direct regional foregone agricultural benefits were relatively low-due to uncertain water supplies and unproductive soils-indicating the market selected a...
