including the economics of Rojava. The influential 1983 anarchist book bolo'bolo, by Hans Widmer, advocated the use of autarky among its utopian anti-capitalist communes (known as bolos), asserting "the power of the State is based on food supply. Only on the basis of a certain degree of autarky can the bolos enter into a network of exchange without being exploited". Widmer theorized that through "tactical autarky" such communes would be able to prevent the return of oppressive structures and a money economy. Autarkic efforts to counter the forcible privatization of public resources and maintain local self-sufficiency also formed a key part of alter-globalization efforts. The Cochabamba Water War had Bolivians successfully oppose the privatization of their water system to keep the resource in public hands. Contemporary Today, national economic autarkies are relatively rare. A commonly-cited example is North Korea, based on the government ideology of Juche (self-reliance), which is concerned with maintaining its domestic localized economy in the face of its isolation. However, even North Korea has extensive trade with Russia, China, Syria, Iran, Vietnam, India and many countries in Europe and Africa. North Korea had to import food during a widespread famine in the 1990s. Some would consider a modern example at a societal level is Rojava, the autonomous northern region of Syria. Despite a key alliance with the United States, supporters consider them largely cut off from international trade, facing multiple enemies, and striving for a society based on communalism, Rojava's government and constitution emphasize economic self-sufficiency directed by neighborhood and village councils. Rojavan society and economics are influenced by Bookchin's ideas, including the emphasis on local and regional self governance. Under changes made in 2012 property and business belong to those who live in or use it towards these goals, while infrastructure, land and major resources are commons run by local and regional councils. Bookchin however was concerned about the effects of isolationist autarky in respect to the closing off of a community and therefore always stressed the need for a balance between localism and globalism. An example of a small, but true autarky is North Sentinel Island, whose native inhabitants refuse all contact with outsiders and live completely self-sufficient lives. An example of a contemporary effort at localized autarky, incorporating the concept's history from black nationalism, Ujamaa, African-American socialism and the civil rights movement, is Cooperation Jackson, a movement aimed at creating a self-sufficient black working
