The Conservation Districts of Iowa passed a resolution earlier this month calling for mandatory buffers to protect the state’s water by prohibiting crops from being planted within 30 feet of a stream. These buffers protect waterways from erosion and nutrient pollution, and also promote biodiversity by preserving habitats. 

The Conservation Districts of Iowa, or CDI, is made up of 500 soil and water conservation district commissioners, elected from each of the soil and water conservation districts in the state. The group’s purpose is to promote conservation practices and policy, and they now plan to lobby the Iowa Legislature on this issue, hoping to pass a law to make buffers mandatory. Minnesota passed a law requiring buffers of 50 feet, and now has a 96% compliance rate.

A similar resolution failed to pass the CDI last year. Laura Krouse, one of the commissioners who proposed the resolution, credits the change in opinion to the heavy precipitation and flooding that the state has experienced over the past year, which hurt farmers across the state. Many farmers already plant perennials around streams, but others don’t, and farmland regulations are expected to meet resistance. 

Opposition Secretary Mike Naig of the Department of Agriculture and Natural Resources said that he opposes making buffers mandatory, preferring voluntary, incentive-driven programs. Krouse responded that Iowa has, “relied on the voluntary approach for 70 years. It’s not working in some areas.”
