Dr. Evan Larson, Professor in the Department of Environmental Sciences and Society, recently had an article published in Water Resources Research, a premier, high-impact journal published by the American Geophysical Union (AGU). The article, entitled “Five Centuries of Groundwater Elevations Provide Evidence of Shifting Climate Drivers and Human Influences on Water Resources in North Central Florida,” is co-authored by Dr. Chris Underwood, also a Professor in the Department of Environmental Sciences and Society, and is a part of a project that has been years in the making. This article reports on a 500-year long reconstruction of groundwater resources in Florida and identifies the impacts of groundwater withdrawals for use in urban and agricultural systems on the resource. Many UW-Platteville students and alumni collaborated on this project as well.
“Human lives are so brief relative to the changes we see in the environment, and our written records are, too,” says Larson. “The expanded perspective on time provided through the rings of trees helps us understand our place in this world more completely, how the world around us is changing, and how our decisions and actions impact the world. This new groundwater reconstruction shows that while deeper and more prolonged droughts than anything experienced during the instrumental record have occurred in the past, the combined influences of climate and water use by people drove recent groundwater elevations to lows comparable to some of the worst droughts in the past five centuries. This understanding, in addition to a curious shifting in the persistence of groundwater elevations apparent in this long record of climate, offers an opportunity to better prepare how we plan for future water resource availability and to get ahead of the impacts that water scarcity can have on economic and ecological systems of northern Florida.”
