Palaeoenvironmental and archaeological investigations have been in progress since 2 years, 70 km upstream from Lyon, in the upper Rhône valley. A multi-disciplinary team (palaeogeography, palaeoecology, archaeology) is attempting to reconstruct the spatio-temporal fluctuations of the nver and their origin through the survey of meandering...

At the transition between the Maya lowlands and the highlands, the northern Alta Verapaz experimented major population movements following the abandonment of several cities as early as the 8th century onwards. This marked the start of what was referred to as the "Maya collapse", which would later extend to the entire lowlands until the 13th...

This paper presents a lake-level record established for the last millennium at Lake Saint-Point in the French Jura Mountains. A comparison of this lake-level record with a solar irradiance record supports the hypothesis of a solar forcing of variations in the hydrological cycle linked to climatic oscillations over the last millennium in...

We review the scientific efforts over the last decades to reconstruct erosion from continuous alpine lake sediment records. We focused both on methodological issues, showing the growing importance of non-destructive high resolution approaches (XRF core-scanner) as well as progresses in the understanding of processes leading to the creation of...

In this paper we review the scientific efforts that were led over the last decades to reconstruct geomorphic patterns from continuous alpine lake sediment records. Whereas our results point a growing importance of humans as erosion forcing factors, we will focus here on climate-related processes. Our main dataset is made of a regional approach...

L'évolution des ressources nécessaires au développement des sociétés dépend de l'évolution des écosystèmes, sous forçages climatique, orbital et sociétal à l'Holocène. Elle entraîne l'apparition de nouveaux risques et de nouvelles vulnérabilités, souvent peu anticipés par les acteurs néolithiques, porteurs d'une nouvelle économie...
