Irrigation Management, Environment, And Profits: Who Wins?, Emily O'Donnell
Irrigation Management, Environment, And Profits: Who Wins?, Emily O'Donnell
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The impact of irrigation technology on farmers’ management strategies and resulting environmental benefits depends upon agronomic properties and market forces. We evaluate the role of deficit irrigation using soil moisture probe technology on corn yield and evapotranspiration, which is a measure of water use efficiency. Evapotranspiration represents the water that transits through the plant during planting to harvest (transpiration) and the evaporation from the soil into the environment, or the displaced water in the production process. We develop yield and evapotranspiration response functions to inform a constrained profit maximization model used to identify the optimal irrigation level across a variety …

Predicting Groundwater Trading Participation In The Upper Republican River Natural Resource District, Elizabeth M. Juchems
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The goal of this thesis is to predict participation in groundwater trading and the directions of trades among participants. Specifically, the paper considers both formal and informal trading of groundwater used for crop irrigation purposes and attempts to identify those characteristics that predict the probability of trade participation and whether an individual is a buyer or seller of groundwater rights. While the public benefits from efficient use of groundwater include adequate stream flow in hydrologically connected areas and future use of groundwater supplies, there are significant private benefits to landowners especially in water-short areas. Groundwater trading can help move water …
