Imagine trying to grow food in a desert with summer heat of 120°F. Jordan’s arid Dead Sea Valley was the site of a “greening the desert” experiment, one of 60 projects profiled in Sustainable [R]evolution: Permaculture in Ecovillages, Urban Farms, and Communities Worldwide by Juliana Birnbaum and Louis Fox, who live in San Geronimo Valley. The book profiles 60 communities, from West Oakland to Zimbabwe, and offers inspiring ways we can act collectively and thrive.
