Agricultural land use change is a major driver of global biodiversity loss and greenhouse gas emissions but also has the potential to part of the solutions to these grand challenges. We study the use of land in the United States—a global agricultural hotspot—to identify opportunities and pathways to improve conservation, mitigate climate change, and continue to meet the needs of society for food, feed, fiber, and fuel. Our research focuses on the characterization and prediction of historic, contemporary, and future changes in our landscapes, quantification of the associated environmental impacts, and evaluation of outcomes from related federal agricultural, energy, and conservation policies.
