China’s Great Famine of 1959–1961 is the deadliest in recorded history, claiming an estimated 30 to 40 million lives. In this episode of VoxDevTalks, Shaoda Wang discusses new research examining one underexplored contributor to that catastrophe: the mass extermination of sparrows under Mao Zedong’s Four Pests campaign. Using historical ecological data and bottom-up crop yield records, his research offers the first rigorous causal estimate of how the loss of a single bird species helped tip a food crisis into a humanitarian catastrophe.
