Virtual Groundwater Transfers from Overexploited Aquifers in the United States

Columbia Water Center Cyberseminar Series

Megan Konar / University of Illinois at Urbana-Champaign

Talk Description:

Irrigated agriculture in the Central Valley of California, High Plains of the Midwest and the Mississippi Embayment accounts for a significant portion of the domestic and international cereal supply, even as it contributes to the depletion of their aquifer systems.

Join us on the next America’s Water Webinar as Megan Konar, assistant professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign explains how her team is tracking and quantifying the food and embodied groundwater resources from these aquifer systems to their final destination and determines the major US cities, US states, and countries that are currently most reliant upon them.

Tracing virtual groundwater transfers highlights the role of distant demands on local groundwater sustainability and the fact that aquifer depletion must be considered within its global context
