CROPLAND CASH RENTAL RATES IN THE UPPER MISSISSIPPI RIVER BASIN AgEcon
Kurkalova, Lyubov A.; Burkart, Christopher; Secchi, Silvia.
The report documents the creation of estimates for cropland cash rental rates in the Upper Mississippi River Basin in 1997. Although the basic data come from disparate sources, we employ a unifying estimation procedure based on the presumption that the cropland cash rental rate is an increasing function of corn yield potential. The rates are estimated at some 42,000 National Resources Inventory data points representing cropland in Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, South Dakota, and Wisconsin.

THE IMPACTS OF CLIMATE CHANGE ON STREAM FLOW IN THE UPPER MISSISSIPPI RIVER BASIN: A REGIONAL CLIMATE MODEL PERSPECTIVE AgEcon
Jha, Manoj K.; Pan, Zaitao; Takle, Eugene S.; Gu, Roy.
We evaluate the impact of climate change on stream flow in the Upper Mississippi River Basin (UMRB) by using a regional climate model (RCM) coupled with a hydrologic model, the Soil and Water Assessment Tool (SWAT). The SWAT model was calibrated and validated against measured stream flow data using observed weather data and inputs from the Environmental Protection Agency's BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) geographical information/database system. The combined performance of the SWAT and RCM was examined using observed weather data as a lateral boundary condition in the RCM. The SWAT and RCM were found to perform well, especially on an annual basis. The potential impacts of climate change on water yield and other...

Economic and Environmental Co-benefits of Carbon Sequestration in Agricultural Soils: Retiring Agricultural Land in the Upper Mississippi River Basin AgEcon
Feng, Hongli; Kurkalova, Lyubov A.; Kling, Catherine L.; Gassman, Philip W..
This study investigates the carbon sequestration potential and co-benefits from policies aimed at retiring agricultural land in the Upper Mississippi River Basin, a large, heavily agricultural area. We extend the empirical measurement of co-benefits from the previous focus on environmental benefits to include economic transfers. These transfers have often been mentioned as a co-benefit, but little empirical work measuring the potential magnitude of these transfers has previously been undertaken. We compare and contrast five targeting schemes, each based on maximizing different physical environmental measures, including carbon sequestration, soil erosion, nitrogen runoff, nitrogen leaching, as well as the area enrolled in the program. In each case, the...
