Global And Regional Assessments Of Unsustainable Groundwater Use In Irrigated Agriculture, Danielle S. Grogan Jan 2016

Global And Regional Assessments Of Unsustainable Groundwater Use In Irrigated Agriculture, Danielle S. Grogan

Doctoral Dissertations

Groundwater is an essential input to agriculture world-wide, but it is clear that current rates of groundwater use are unsustainable in the long term. This dissertation assesses both current use of groundwater for country- to global-scale agriculture, and looks at the future of groundwater. The focus is on 1) quantifying food directly produced as a result of groundwater use across spatially-varying agricultural systems, 2) projecting future groundwater demands with consideration of climate change and human decision-making, and 3) understanding the system dynamics of groundwater re-use through surface water systems. All three are addressed using a process-based model designed to simulate …


The Golden Pandemic, Leo Dylan Stevens-Lubin Jan 2016

The Golden Pandemic, Leo Dylan Stevens-Lubin

Senior Projects Spring 2016

The work in my senior show is a representation on how I feel about conventional focusing specifically on corn. The reason that I have chosen corn is because it is one of the most detrimental crops that we are growing in the US. It is grown specifically for livestock feed and ethanol with a minimal fraction for direct human consumption. Corn itself offers minimal nutritional benefits in comparison to most other vegetable crops and the overproduction of corn crops decreases the benefits all the more.

Role Of Multiple High-Capacity Irrigation Wells On A Surficial Sand And Gravel Aquifer, Logan Seipel, Eric Wade Peterson, David H. Malone, Jason F. Thomason Dec 2015

Role Of Multiple High-Capacity Irrigation Wells On A Surficial Sand And Gravel Aquifer, Logan Seipel, Eric Wade Peterson, David H. Malone, Jason F. Thomason

Eric Wade Peterson

Within McHenry County, IL, the fastest growing county in Illinois, groundwater is used for 100% of
the water needs. Concerns over water resources have prompted the investigation of the surficial
sand and gravel aquifers of the county. While the eastern portion of the county is urbanizing, the
western portion remains devoted to agriculture. High-capacity irrigation wells screened within
the surficial sand and gravel aquifer are used for crop production. To assess the impacts of the ir-
rigation wells on the aquifer, a groundwater flow model was developed to examine five different
scenarios reflecting drought conditions and increased pumping. Results show …
