Irrigation Technology Transitions in the Mid-plains States: Implications for Water Conservation/Water Quality Goals and Institutional Changes

摘要

A Parks modified multinomial logit model is used to examine the influence of the agricultural economic environment on irrigation technology transitions in the mid-plains states. Simulation analyses assess expected agricultural water conservation and its implications for water quality/environmental goals and water institutional reform. Under baseline agri-economic assumptions, regional agricultural water use efficiency could improve from 2.3% to 9.8%. Technology-specific elasticities show that crop price effects on irrigation technology transitions are relatively inelastic. Results for the mid-plains states differ from those obtained for the Pacific north-west (an earlier study), implying that differentially endowed resource regions will likely require different resource conservation policy and institutional approaches.
