Pollution and eutrophication of Chinese lakes are widely perceived to be 20th century phenomena. However, China has a long history of deforestation, agriculture, mineral resource extraction, and other anthropogenic activities that impact the environment. Here, we present a sediment record from Xing Yun Lake in the Yunnan Province of China that reveals significant alterations to the lake, its ecosystem, and its watershed beginning as early as 500 AD. A comprehensive suite of biogeochemical and isotopic proxies reveal several rapid transitions related to changes in agriculture and lake-level management that coincides with cultural and dynastic transitions. The deterioration of contemporary environmental conditions at Xing Yun arises from a long history of anthropogenic manipulation, eutrophication, and pollution of the lake and its watershed. This study highlights the importance of using historical records of industrial and agricultural activities, including landscape modification, in conjunction with records of climate change, to place present day environmental concerns into a long-term context. STUDY NOTES: Stable isotope and elemental data from sediments collected in Xing Yun Lake, Yunnan, China. Data include concentration and isotopic composition of organic carbon and nitrogen (%C, d13Corg, and d15Norg), the oxygen and carbon isotopic composition of authigenic calcite (d18Ocarb and d13Ccarb), and elemental concentrations in sediment. Cores were collected in the deepest (northern) portion of the lake, 11m water depth.
