Histories of science in modern China often explore their subjects within global or national frameworks. This essay uses data from gazetteers to address the place-based nature of Chinese agricultural science as it developed at smaller geographical scales. Information contained in gazetteers suggests that regional environmental knowledge and site-specific social networks influenced the construction and communication of scientific ideas about farming at the local level. By highlighting these dimensions of knowledge making, this essay demonstrates the benefits of using gazetteers to grapple (...) with the importance of place in Chinese science. (shrink)
