The Great Smog of China traces Chinese air pollution events dating back to more than 2,000 years ago. Based on the authors’ fieldwork, interviews and text studies, the book offers a short and concise history of selected air pollution incidents that for varying reasons prompted different kinds of responses and forms of engagement in Chinese society. The three authors, from the disciplines of anthropology, China studies and political science, identify traceable incidents of smog and air pollution that have been communicated in different media and came to impact society in various ways. This also informs a discussion of what it takes to transform people’s experiences of health and environmentally related risks of pollution into broader forms of socio-political agency.
