A MULTICROP PRODUCTION MODEL OF IRRIGATED AGRICULTURE, APPLIED TO WATER ALLOCATION POLICY OF THE BUREAU OF RECLAMATION AgEcon
Moore, Michael R.; Negri, Donald H..
Recipients of irrigation water from the Bureau of Reclamation (BuRec) face a future of water conservation. By formally modeling surface water as a fixed, allocatable input to a multioutput firm, this research captures the institutional constraints governing water allocation and , simultaneously, establishes a cohesive approach to analyzing the production effects of BuRec allocation policy. Econometric results show that BuRec-served irrigators'’ crop supply and land allocation decisions are generally inelastic with respect to the water constraint. Using the elasticities, a policy simulation of a 10% reduction in BuRec water allocation indicates that production response to reduced water supply would affect the national price of three of ten major crops...

DETERMINANTS OF IRRIGATION TECHNOLOGY CHOICE AgEcon
Negri, Donald H.; Brooks, Douglas H..
Two discrete choice models relate the probability of choosing two water-saving irrigation technologies - —sprinkler and tailwater recovery pits- —to the underlying physical and economic attributes of the farming using a national cross section of farm level data. The results show that small farm size, high water or labor costs, and soils with low water-holding capacity increase the likelihood of adopting sprinkler irrigation. For gravity irrigators, large farms, high water costs, and solid with high water-holding capacity increase the probability of recirculating field runoff. In both models soil characteristics and, to a lesser extent, climate dominate the selection probabilities.
