Farmers of Forty Centuries

Farmers of Forty Centuries, published in 1911 by the American agricultural scientist Franklin Hiram King, is a landmark study in the history of agronomy and environmental thought. Based on King’s travels through China, Korea, and Japan in 1909, the book provides a detailed account of traditional agricultural methods that had sustained intensive food production over thousands of years. King emphasizes techniques such as composting, crop rotation, irrigation management, and the recycling of organic waste, contrasting these sustainable practices with the soil-depleting methods then common in Western industrial agriculture. Beyond its descriptive ethnographic value, the work functions as a critique of Western assumptions about agricultural “progress,” presenting East Asian practices as models of ecological balance and resource conservation. The book has since been recognized as an influential precursor to modern sustainability discourse, permaculture theory, and organic farming movements, highlighting the relevance of traditional ecological knowledge in addressing contemporary environmental challenges.
