Wetlands play a vital role in protecting against flood damage, as seen during floods in eastern South Dakota this June. However, researchers warn that industrial agriculture expansion in the Midwest threatens these natural barriers.
A report from the Union of Concerned Scientists reveals that 30 million acres of Upper Midwest wetlands are at risk from industrial agriculture and other industries. This risk has been heightened by a recent U.S. Supreme Court decision weakening federal wetlands protections.
"What we do on our landscape will directly impact the damage and the severity of those floods on our private properties, on our farm fields and our businesses and our urban settings," explains the managing director of Friends of the Big Sioux River.
South Dakota currently has no state-level wetland protection policies. Weaker federal protections and the absence of state measures leave wetlands more vulnerable. The pending Farm Bill could offer an opportunity to strengthen conservation programs.
Wetlands are crucial for flood mitigation, capturing and slowing floodwaters before they threaten homes. According to the Union of Concerned Scientists, wetlands provide $745 in flood mitigation benefits per acre. Without these natural barriers, homeowners and taxpayers face higher costs through programs like the National Flood Insurance Program.
In addition to flood control, wetlands are vital for maintaining water quality. "They're often called 'nature's kidneys,' because they provide such a service in cleaning our waterways," explains the food and environment research director for the Union of Concerned Scientists. However, runoff from pesticides, fertilizers, and other pollutants can impair their ability to filter water.
Protecting wetlands is essential to mitigate flood risks and maintain water quality. Conservation policies must address these threats to ensure the sustainability of South Dakota’s natural resources.
