Holocene fire activity during low-natural flammability periods reveals scale-dependent cultural human-fire relationships in Europe

2018

Abstract Fire is a natural component of global biogeochemical cycles and closely related to changes in human land use. Whereas climate-fuel relationships seem to drive both global and subcontinental fire regimes, human-induced fires are prominent mainly on a local scale. Furthermore, the basic assumption that relates humans and fire regimes in terms of population densities, suggesting that few human-induced fires should occur in periods and areas of low population density, is currently debated. Here, we analyze human-fire relationships throughout the Holocene and discuss how and to what extent human-driven fires affected the landscape transformation in the Central European Lowlands (CEL).

Neolithic Human Societies and Woodlands in the North-Western Mediterranean Region: Wood and Charcoal Analysis

2017

An overview of woodland history in the north-western Mediterranean region, based on charcoal analysis (Anthracology) from Mesolithic and Neolithic sites, is proposed for the Mediterranean areas of France, Spain and Portugal. The taxonomic identification of charcoal fragments and the diachronic variations of taxa frequencies provide, for each settlement, an accurate image of the local vegetal cover. During the end of the last glaciation, beginning of the Holocene, vegetation dynamics reflects the evolution of climatic and geographic conditions. Any potential ecological impact by hunter-fisher-gatherer communities (Mesolithic) remains invisible; the same comment applies to the farming-herding…

First archaeobotanical mentions of hemp leaved nettle ( Urtica cannabina ), in association with hemp ( Cannabis sativa ), on two sites in Champagne

2021

La culture du chanvre (Cannabis sativa) semble maintenant bien renseignée à partir du Xe siècle de notre ère en France septentrionale (Boulen et Zech-Matterne 2012), et l’utilisation des orties pour leurs fibres, généralement l’ortie dioïque (Urtica dioica), est également avérée. Toutefois, l’ortie à feuille de chanvre (Urtica cannabina) n’avait encore jamais été mentionnée parmi les études bioarchéologiques (pollen et macrorestes). Cette espèce a cependant été découverte pour la première fois à l’occasion d’une étude palynologique dans un contexte daté du XIVe siècle du site de Bezannes « le Village » (51), fouillé en 2013 (Gucker et al., en cours). Une fouille très récente à Troyes « Plan…

Mapping intra-plot topsoil diversity of Burgundy vineyards (Aloxe- Corton, France) from very high spatial resolution (VHSR) images

2012

International audience; In this work, we present a method based on very high spatial resolution (VHSR) aerial images acquired in the visible domain and that map soil surface diversity at the hillslope scale with a spatial resolution of a few centimeters. This method combines aerial VHSR image classification with local soil sampling. Principal component analysis (PCA) and non-supervised classification was performed on image characteristics to define soil surface characteristic classes (SSC). Then soil surface mapping was combined with soil surface descriptions and soil profiles to define soil types by physical and chemical characteristics.

En direct de l’essai patrimonial des 42 parcelles d’INRAE à Versailles : impacts de fertilisations centenaires en profondeur du NEOLUVISOL de lœss

2020

International audience; Après l’étude d’évolutions pédologiques et géochimiques dans l’horizon de surface (van Oort et al., 2016, 2017a), ce nouveau volet du projet de valorisation du dispositif des 42 parcelles de l’Inra de Versailles présente les effets d’apports continus de matières fertilisantes à l’échelle du solum, pour une dizaine de traitements : ammoniacaux, engrais-Na et/ou K, phosphatés, CaCO$_3$, fumier et témoins. Pour chaque traitement, les profils de teneur en éléments (0-120 cm) ont été comparés avec le bilan 1929-2014 en surface (0-25 cm), afin de raisonner la pertinence d’études des impacts d’activités anthropiques, restreintes à l’horizon de surface. En l’absence de végét…
