Las sociedades andinas se enfrentaron y siguen enfrentándose a diversas crisis como fenómenos El Niño, terremotos, cambios de poder, crisis económicas, migraciones, modificaciones del territorio y de las fronteras. Ya sean climáticas, sociales, políticas o económicas, temporales, cíclicas o de más larga duración, las crisis generaron diferentes tip...

The Sechura Desert provides a unique example of a vast palaeo-lagoon system on the Peruvian coast that was active during the first millennium AD. Reconstruction of coastal evolution is made possible by the good resolution of the sedimentary records of the Las Salinas Noroeste coastal plain. Evidence from morphostratigraphy and sedimentary facies in...

The western coast of the Sechura Desert, with its specific geographical and archaeological settings, allows a geoarchaeological study based on the crossing of excavations and geormorphological pit data. Indeed, the Las Salinas depression, which is today arid and flooded only during the major El Niño events, has a strong potential in term of socio-e...

The Lake Van (1648 m) is a palaeoclimatic and palaeoenvironmental reference for the Middle East. According to previous studies, its evolution since the last 20000 years appears close-related to post-Glacial climatic changes. Our PhD thesis aimed at reconstructing the ancient lake levels during more than 100 000 years, a period corresponding to the...

Vine introduction in Burgundy (east central France) two millennia ago is responsible for land use changes and increased soil erosion to which societies have tried to adapt. In this paper we seek to figure out the relationship between land uses, agricultural practices and geomorphic dynamics in the Mercurey terroir during the Late Holocene. The meth...
Chapter
Chapter 11 reviews research at Bayovar-01, a site in the Sechura Desert of far northern Peru that dates to the transition between the Early Intermediate Period and the Middle Horizon (roughly between 550 and 770 cal AD). Situated in front of a paleolagoon that was only wet occasionally, the authors suggest that Bayovar-01 was a specialized fishing...

Lake Van is the largest soda lake in the world. It is a terminal lake, surrounded by mountains rising to 3500 m a.s.l. The Lake Van Basin is divided into three geological and morphological units: (1) the mostly metamorphic Bitlis Massif pertaining to the Bitlis suture zone to the south-west; (2) Mesozoic and Tertiary rocks (carbonates and volcanics...

Burgundy (France) is one of the world's most famous land for wine making and its "Climates" were inscribed on the UNESCO's World Heritage List in 2015. Yet, vineyards are known to undergo the most substantial soil loss in Europe. They have to face a serious ongoing environmental degradation risk, major financial and social loss for winemakers and l...

We present here recent results of a geoarchaeological study on the Northern coast of Peru. Concerning the scientific context, excavation of new or already known archaeological sites in the Sechura Desert, since 2012, revealed the high potential of the area to reconstruct Human-Environment interactions during the last two millennia at least. The pre...

The Lake Van (1648 m) is a palaeoclimatic and palaeoenvironmental reference for the Middle East. According to previous studies, its evolution during the last Glacial appears close related to climatic changes. In the Karasu valley (eastern part of the Lake Van basin), coupled sequence stratigraphy and OSL datings, allowed to give a chronological fra...

Le lac de Van, dans les montagnes d’Anatolie orientale, ne possède pas d’exutoire naturel. Malgré son volume (604 km3), les amplitudes des variations de son niveau témoignent, depuis 1944, d’une sensibilité élevée aux fluctuations hydro-climatiques. Dans cette perspective, les dépôts hérités d’anciens hauts niveaux, conservés sous forme de terrasse...

Located in eastern Anatolia (Turkey), Lake Van is the fourth largest lake in the world. Along the banks of the lake, several lake terraces record Pleistocene variations of the lake levels. In the terraces, the lake deposits are often interbedded with pyroclastites emitted by the volcanoes located on the northern side of the lake. Our research focus...

Full-text available
In the eastern Anatolian Mountains, the relatively high-magnitude variations exhibited by the level of Lake Van in recent years indicate, as the lake has no outlet, that this level can be considered as a sensitive indicator of climate if these variations respond to changes in water input/output. Until now, previous palaeoclimatic research has focus...

Article
Sedimentological and geomorphological studies of terraces around Lake Van (1647 m) provided a preliminary framework for lake-level variations. The elevations of terraces and past lake level were measured with a differential global positioning system. A chronology is developed using 234U/230Th dating of travertines, 39Ar/40Ar dating of pyroclastites...
Article
Soda Lake Van is a very important reference site for Late Glacial and Holocene palaeoenvironmental records in the Caucasus, Near and Middle East. Influenced by past climatic regimes, changes in the hydrology of Lake Van being very sensitive to humidity and temperature changes, past climates and environments have been studied from deep lake sediment...

Many authors asked to focus on the concept of sediment connectivity to predict the sedimentary signal delivered at catchment outlets. In this framework, the sedimentary signal is seen as an emergent organization of local links and interactions. The challenge is then to open black boxes that remain within a sediment cascade, which requires both accurate geomorphic investigations in the field (reconstruction of sequences of geomorphic evolution, description of sediment pathways) but also the development of tools dedicated to sediment cascades modeling.
