| The adoption of conservation tillage practices such as ridge till, mulch till, or no-till has been shown to reduce soil erosion. An additional benefit of these conservation practices is that they also increase soil moisture. Therefore, these practices appear to be a method that agricultural producers can use to reduce their risk associated with abnormally dry or wet conditions (i.e., drought or flood). Given the large amount of money spent by the USDA on crop insurance indemnity and ad-hoc disaster relief payments, practices that reduce the risk of drought to the farmer should be strongly encouraged. Using SUR estimation with random effects, the paper uses panel data to measure the impact of extreme weather events on the adoption of conservation tillage.... |

| The paper combines panel data techniques with spatial analysis to measure the impact of extreme weather events on the adoption of conservation tillage. Zellner’s SUR technique is extended to spatial panel data to correct for cross-sectional heterogeneity, spatial autocorrelation, and contemporaneous correlation. Panel data allow the identification of differences in adoption rates. The adoption of no-till, other conservation tillage, and reduced-till are estimated relative to conventional tillage. Extremely dry conditions in recent years increase the adoption of other conservation tillage practices, while spring floods in the year of production reduce the use of no-till practices. |

| This research analyzes two groundwater conservation policies in the Kansas High Plains located within the Ogallala aquifer: 1) cost-share assistance to increase irrigation efficiency; and 2) incentive payments to convert irrigated crop production to dryland crop production. To compare the cost-effectiveness of these two policies, a dynamic model simulated a representative irrigator’s optimal technology choice, crop selection, and irrigation water use over time. The results suggest that the overall water-saving effectiveness can be improved when different policy tools are considered under different conditions. High prevailing crop prices greatly reduce irrigators’ incentive to give up irrigation and therefore cause low enrollment and ineffectiveness of the... |
