Biomarker signatures of former soil uses. A case study from the catchment area of Lake Aydat (Massif Central, France).

Abstract : The history of human land use vs climate impacts on natural environments is of direct relevance in the perspective of future climate change and increasing human pressure on ecosystems. Although these impacts were discrete before agriculture and breeding development, they became critical after the industrial revolution, due to the massive anthropization of terrestrial surfaces. Natural archives such as soils and sediments potentially preserve information about past land uses. As a matter of fact, soils are reputed to retain the signature of their ancient uses [1] and lacustrine sediments integrate the evolution of environmental conditions that prevailed in the catchment basin through time.
