Earth Day speaker on DSU campus this Thursday

The College of Arts and Sciences is hosting an Earth Day Speaker on Thursday, April 25, at 7:00 p.m. in the Science Center auditorium on the Dakota State University Campus.

Dr. Christopher Wright will speak on his paper published in the Proceedings of the National Academy of Sciences of the United States of America titled, "Recent land use change in the Western Corn Belt threatens grasslands and wetlands".

The paper discusses how in the U.S. Corn Belt, a recent doubling in commodity prices has created incentives for landowners to convert grassland to corn and soybean cropping. With respect to agronomic attributes of lands undergoing grassland conversion, corn/soy production is expanding onto marginal lands characterized by high erosion risk and vulnerability to drought. Grassland conversion is also concentrated in close proximity to wetlands, posing a threat to waterfowl breeding in the Prairie Pothole Region.

This paper received much national and regional attention in newspapers such as the New York Times, the Washington Post and the Madison Daily Leader.
