Freshwater habitats account for less than 1% of the world's surface and only 0.01% of the world's water, but support 25% of all described vertebrates, over 126,000 animal species, and 2,600 macrophyte plants.
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.
