The internationalization of economies and other changes that accompany globalization have brought about a paradoxical reemergence of the local. A significant but largely unstudied aspect of new local-global relationships is the growth of "localist movements"--efforts to reclaim economic and political sovereignty for metropolitan and other subnational regions. Hess offers an overview of localism in the United States and assesses its potential to address pressing global problems of social justice and environmental sustainability. Hess looks at four specific forms of localism: "buy local" campaigns; urban agriculture; local ownership of electricity and transportation; and alternative and community media. He then examines "global localism"鈥攖ransnational local-to-local supply chains鈥攁nd other economic policies and financial instruments that would create an alternative economic structure. Localism is not a panacea for globalization, he concludes, but a crucial ingredient in projects to build more democratic, just, and sustainable politics.
