摘要

有效的灌溉管理对未来的粮食供应和从事灌溉生产的生产者的繁荣至关重要。通过赤字灌溉田间试验,我们确定了灌溉成本、玉米价格、极端天气事件和限制灌溉水平对生产者造成的财务影响。结果表明,在我们的约束优化模型中,最优经济策略是充分灌溉,其经济影响高度依赖于商品价格、限制水平和灌溉成本。灌溉限制造成的最大经济损失来自产量的下降。一些模拟结果是负利润,这表明可能有必要转向需要较少灌溉的替代作物。

Economics of deficit irrigation utilizing soil moisture probes in the western corn belt
Effective irrigation management is critical for future food supplies and the prosperity of producers engaged in irrigation production. Through a deficit irrigation field experiment, we determine the financial impact on producers caused by changing irrigation costs, corn prices, extreme weather events, and restricting irrigation levels. Results suggest that the optimal economic strategy within our constrained optimization model is to fully irrigate, with the economic impact highly dependent on commodity prices, restriction level, and irrigation costs. The greatest economic losses caused by irrigation restrictions come from decreases in yield. Some simulations resulted in negative profits, indicating that a switch to alternative crops requiring less irrigation may be warranted.

期刊介绍: The purpose of the Review is to foster and disseminate professional thought and literature relating to the economics of agriculture, natural resources, and community development. It is published twice a year in April and October. In addition to normal refereed articles, it also publishes invited papers presented at the annual meetings of the NAREA as well as abstracts of selected papers presented at those meetings. The Review was formerly known as the Northeastern Journal of Agricultural and Resource Economics
