Summary: Bioenergy is of increasing interest in agriculture as biomass becomes the largest source of renewable energy in the United States. This project documents the current and future land use patterns of perennial biomass crops in the Midwest using satellite image series, and assesses the environmental impacts, e.g. soil erosion and environmental sensitive lands in the Corn Belt. The deliverables of this project include:

  • the km-scale perennial grass and biomass maps in the Midwest;
  • fine-resolution documentation of perennial grass establishment in the BCAP Project Area 1;
  • perennial crop inventory database in the Midwest in 2000-2015;
  • Soil erosion and environmental sensitivity assessment under bioenergy land use changes at local (BCAP land) and regional (Midwest) levels.
