Voluntary Nutrient Reduction Strategy Will Not Work

The science assessment of nonpoint source practices in the Nutrient Reduction Strategy (NRS) is comprehensive.  However, it reveals that major changes in Iowa’s agricultural practices will be required to achieve the goals of the NRS.  What is lacking in the NRS is a plausible strategy for how farmers will become motivated to make those changes.

The practices listed in the NRS are not new.  Farmers have had the opportunity to adopt them for years, but for the most part they have not.  The reason they haven’t is that the practices cost money and/or time to implement.  Farmers, individually, have no economic motivation to adopt them, and the public cannot afford to pay for them.

In 2012 USDA provided Iowa landowners $33 million in conservation funding, the latest of decades of annual conservation funding that has not shown real gains in water quality.  To the contrary, the Hypoxia Zone in the Gulf of Mexico has grown larger over the decades of state and federal funding of water quality programs and projects.  Moreover, anyone driving around Iowa in recent years has seen firsthand that a lot of new tile drainage has been installed across Iowa, which will likely increase the loss of nitrogen to the Gulf faster than water quality projects can make gains.  The proposed $2.4 million state allocation to implement the NRS may sound like a lot to legislators and the public, but it is a drop in the bucket of funding that would be required if the public were to fund the NRS to a level that would have a chance of achieving its goals.

A water quality strategy that could work would be to require every farm to develop and implement a farm conservation plan which would include a combination of practices from the science assessment of the NRS, which together would meet the water quality goals for that farm, and which on the aggregate would meet the water quality goals for the State of Iowa.  Motivation for farmers to develop and implement their conservation plans could be through coupling conservation plans to federal subsidy programs (obviously the state cannot control that) or through direct regulatory requirements at the state or federal level.

The voluntary strategy put forth in the NRS simply defies the odds of working.  As one ISU scientist -- who contributed to the science assessment of the NRS – recently told me, “There is no scientific evidence that the NRS strategy will work.”

At best, the proposed voluntary approach espoused in the NRS represents a naïve belief that farmers will now suddenly make major changes in their farming practices – which will cost them money – in the face of decades of evidence to the contrary.  At worst, the NRS strategy could be seen to be a calculated ploy to try to buy another five years of business-as-usual agriculture under the guise of a new strategy.
