Ernest Callenbach

In 2009, Callenbach was awarded an honorary doctorate by the University of Freiburg. Freiburg is noted for its renewable energy industry and has been called a "green utopia". He died of cancer on April 16, 2012 in Berkeley, California.

In 2006 Callenbach introduced the story of a real-world community movement in Japan that is reminiscent, in its aims and practices, of his Ecotopian society. He visited Japan and investigated the Yamagishi movement. He found that it encompassed some three dozen intentional communities founded on the same underlying principles: living an ecologically based integration of people with agriculture (pig, cattle, and chicken livestock raising, and organic-vegetable and fruit farming), and living a social life based on principles of democracy, mutual understanding, support, and health. Each individual settlement is referred to as jikkenji ('demonstration community for the world').

Callenbach is known as an author of green books, namely as author of the ecological "utopias" Ecotopia (1975) and Ecotopia Emerging (1981), and also The Ecotopian Encyclopedia (1981), Bring Back the Buffalo! (1995), and Ecology: A Pocket Guide (1998). (While his first novel popularized the term "ecotopia," the term was actually coined by the ethnographer E. N. Anderson.)

Callenbach then moved to California. From 1955 to 1991, he was on the staff of the University of California Press (Berkeley). A general copywriter for a number of years, he edited the Press's Film Quarterly from 1958 until 1991. He also occasionally taught film courses at U.C. and at San Francisco State University.

Ernest Callenbach (April 3, 1929 – April 16, 2012) was an American author, film critic, editor, and simple living adherent. He became famous due to his internationally successful semi-utopian novel Ecotopia (1975).
