| 简介： | Agricultural production and water resources are sensitive to climate variability and change. Decadal climate variability (DCV) is another force that has been found to influence crop yields and water supplies. DCV phenomena are in early stages of being explored. This thesis explores the regional impact analysis of increased drought frequency on water management, estimates the effects of DCV on crop yields in the Edwards Aquifer (EA) region of Texas, and appraises the regional value of DCV information. We find that increased drought frequency will cause a regional agricultural loss of $6.47 million per year with substantial land transferred to grazing. We also find that the average economic value of a perfect DCV forecast is $40.25 million per year. |
