The average fraction of disposable income spent on food, beverages, and tobacco ranges from 17% in high-income countries to 53% in low-income countries. Americans typically devote less than 10% of their budget for this purpose, whereas the average Nigerian may have to spend 73% of his disposable income.
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.
