George Martin is an environmental sociologist, Emeritus Professor of Sociology at Montclair State University, Visiting Professor at the Centre for Environmental Strategy at the University of Surrey, CPE researcher, and a senior editor of the journal Capitalism, Nature, Socialism. His current work documents and supports the expansion of sustainable food production in urban settings. His primary argument: Community gardens and farms and other forms of urban agriculture represent far more than food; they generate social capital that drives community development, promotes environmental education, and advances environmental justice–all of which are critical to social sustainability.
