From Adaptation to Breakdown: Traditional Knowledge and the 1929 Famine in Shaanxi, China

Traditional knowledge has long shaped how agrarian societies perceive climatic variability and organize responses to environmental risk, yet its limits under unfamiliar and extreme climate shocks remain insufficiently examined. The 1928–1930 North China famine—one of the most severe climate–society crises in twentieth-century China—offers a crucial lens through which to probe these boundaries. Drawing on local archives, relief reports, and high-resolution climate reconstructions, this study reconstructs the knowledge structures and institutional context surrounding the 1929 Shaanxi famine. It shows that both public discourse and official governance consistently framed the crisis as a “drought.” In reality, however, agricultural collapse stemmed from the compound shock of prolonged aridity and anomalously severe cold. Local relief networks—grounded in Confucian ethics and experiential agricultural knowledge—displayed cognitive lag and coordination breakdown when confronted with cold-related crop failures, revealing a structural mismatch between inherited knowledge, institutional routines, and a rapidly shifting environmental reality. The analysis demonstrates that the making of historical disasters was shaped not only by climatic extremes but also by the fragile interactions among knowledge systems, social institutions, and environmental change. This case provides critical insight into how contemporary societies may misread climate risks and miscalculate policy responses under accelerating climate uncertainty.
