Understanding human–environment interactions during the Quaternary is essential for interpreting past landscape change. Lake sediments provide continuous and well-preserved archives of ecological and climatic variability, often capturing clear signals of human impact. This session invites studies that use lake sediment proxies such as lipid biomarkers, sedimentary ancient DNA, charcoal, pollen, stable isotopes, and elemental geochemistry to reconstruct the timing, intensity, and nature of anthropogenic influence. We encourage submissions that apply multiproxy approaches, develop or refine proxy methods, and work to distinguish human activity from climate-driven change. Case studies that integrate sediment archives with archaeological or historical evidence, as well as regional syntheses of land use and ecological response, are particularly welcome.
