Iowa Nutrient Reduction Strategy annual report now available


December 15, 2017, Des Moines, IA – Iowa State University, the Iowa Department of Agriculture and Land Stewardship and the Iowa Department of Natural Resources today highlighted the Iowa Nutrient Reduction Strategy Annual Progress Report that is now available at http://www.nutrientstrategy.iastate.edu/documents.

The annual report provides progress updates on point source and nonpoint source efforts to reduce nitrogen and phosphorus loads leaving the state. The report follows the “logic model” framework that identifies measurable indicators of desirable change that can be quantified, and represents a progression toward the goals of achieving a 45 percent reduction in nitrogen and phosphorus loads leaving the state.

“There are a wide variety of factors that impact water quality and this report seeks to identify and quantify all of the work being done,” said Iowa Deputy Secretary of Agriculture Mike Naig. “We continue to see progress among all aspects of measures that have been identified, we just need to continue to accelerate and scale-up our efforts.”

“We continue to focus highly on the main goal of water quality improvement and it is gratifying to see we are moving in that direction,” said Iowa DNR Director Chuck Gipp. “A great deal of collaboration and cooperation has taken place which has enhanced and continues to enhance the partnerships and teamwork being done to successfully meet our end goals.”

The “logic model” framework recognizes that in order to affect change in water quality, there is a need for increased inputs, measured as funding, staff, and resources. Inputs affect change in outreach efforts and human behavior. This shift toward more conservation-conscious attitudes in the agricultural and point source communities is a desired change in the human dimension of water quality efforts.

With changes in human attitudes and behavior, changes on the land may occur, measured as conservation practice adoption and wastewater treatment facility upgrades. Finally, these physical changes on the land may affect change in water quality, which ultimately can be measured through both empirical water quality monitoring and through modeled estimates of nutrient loads in Iowa surface water.

“While it will take time to reach the 45 percent reduction goal, the indicators we track are moving in the right direction,” said John Lawrence, interim vice president of extension and research at Iowa State University.

The report was compiled by the Iowa Nutrient Research Center at Iowa State University with support from the Iowa Department of Agriculture and Land Stewardship and the Iowa Department of Natural Resources. A draft of the report was shared with the Iowa Water Resources Coordinating Council in late September and their feedback was incorporated into the recently finalized report.
