Projects: Research and Assess the Farmer and Mn/DOT Economic and Environmental Costs and Benefits of Living Snow Fences Including Carbon Impacts

Topics: Economics, Environment, Snow and Ice Control

Blowing and drifting snow on Minnesota's roadways is a transportation efficiency and safety concern. Establishing standing corn rows and living snow fences improves driver visibility, road surface conditions, and has the potential to lower costs of road maintenance as well as accidents attributed to blowing and drifting snow. It also has the potential to sequester carbon and avoid the carbon emissions of snow removal operations. In recent years the Minnesota Department of Transportation (MnDOT) has paid farmers to leave standing corn rows to protect identified snow problem roadways. They have paid farmers $1.50 per bushel above market price. With increasing demand for corn to fuel the ethanol industry, paying $1.50 per bushel above market price may not be sufficient incentive for leaving standing corn rows. Also, with MnDOT's memorandum of understanding with USDA to plant living snow fences through the Conservation Reserve Program (CRP), now is an opportune time to review MnDOT's annual payment structure to farmers and prepare a new one. This project has: 1) developed a calculator to estimate payments for farmers that includes consideration of safety and snow removal cost savings; 2) estimated potential income from carbon payments; 3) worked closely with MnDOT engineers and plow operators, estimated the safety and snow removal costs and carbon emissions avoided by MnDOT through establishing living snow fences; and 4) evaluated farmers' willingness to establish living snow fences and identified farmers/landowners' constraints to adoption. Data is provided to MnDOT to assist staff in its decision making related to their Living Snow Fence Program.
