Approximately 83% of the U.S. population lives in urban areas - a significant increase from 67% in 1950. By 2050, 90% of the U.S. population and 70% of the world population is projected to live in urban areas.
The need for global solutions to environmental, social, and economic challenges is greater than ever. The Center for Sustainable Systems, within the School of Natural Resources and Environment at the University of Michigan, leads interdisciplinary research to support the design, assessment, and management of systems that meet societal needs in a more sustainable manner.
