Lacustrine sedimentary archives provide clue information on past Human-climate-environment interactions in order to predict the future responses of societies and ecosystems to global climate change. Within a multidisciplinary project aiming at documenting these interactions during the Holocene in the French Alps, we have examined by gas chromatography-mass spectrometry the lipid content of a sedimentary series covering the last 6 ka, drilled in Lake le Bourget (core LDB04, Fig. 1A).
