Humans have and are likely to continue to dramatically alter both the global landscape through the conversion of natural ecosystems into agriculture and the atmosphere through the combustion of biomass and fossil fuels. Associated with these land use and global changes are major alterations in the biogeochemical cycles of carbon, water, and nitrogen, which have important implications on the growth and function of ecosystems and the services they provide for humanity. In the Midwestern United States, agriculture dominates the landscape, thus it is important to characterize the dynamics of this major agro-ecosystem associated with aspects of land use and global change. In this presentation, the primary focus will be on an in-depth investigation of land use change for cellulosic feedstocks in the Midwestern United States and the implications on water quantity and quality in a regional context. I will also highlight investigations of the regional scale impacts on water-related agro-ecosystem services associated with global change factors including increasing concentrations of carbon dioxide and the tropospheric pollutant ozone.
