Pollen and sediment evidence for late-Holocene human impact at the Seonam-dong archeological site, Gwangju, Korea

► We present multiproxy evidence for human impact during late-Holocene in SW Korea. ► Our data indicate a climatic deterioration in SW Korea during AD200 - AD800. ► We hypothesize how people responded to climate change. ► A possible link between climate, cultivation, and forest ecosystems is suggested.
