For the past four decades, the ‘Secondary Products Revolution’ model, i.e., the exploitation of animal resources that do not involve killing the animal, such as the production of milk and wool and the use of animals for physical labour has been the object of heated discussion between Neolithic scholars. According to this model, the use of animal st...
The Alps have historically been crossed by populations moving between northern and southern Europe for various purposes. Testimonies of such human presence were long preserved from decomposition being covered and protected by perennial ice and snow. However, with ongoing climate change, large portion of these permanent snowed and frozen areas are b...
While narratives of the spread of agriculture are central to interpretation of African history, hard evidence of past crops and cultivation practices are still few. This research aims at filling this gap and better understanding the evolution of agriculture and foodways in West Africa. It reports evidence from systematic flotation samples taken at...
The central Nigerian Nok Culture is known for its elaborate terracotta figurines and iron metallurgy of the first millennium BC. Since 2005, Goethe University Frankfurt has carried out comprehensive research on this otherwise hardly known cultural complex, focusing on chronology, the structure and function of sites and their reoccupation, environme...
Many societal and environmental changes occurred between the 2nd millennium BC and the middle of the 2nd millennium AD in western Africa. Key amongst these were changes in land use due to the spread and development of agricultural strategies, which may have had widespread consequences for the climate, hydrology, biodiversity, and ecosystem services...
The so-called Phoenician or Punic eye beads are a well-known type of glass artefacts circulating all over the Mediterranean Basin and Europe for most of the 1st millennium BCE. Glass beads were mostly produced in secondary workshops from imported raw glass or recycled artefacts but the specific sites of manufacture remain difficult to locate. Never...
Many societal and environmental changes occurred from the 2nd millennium BC
to the middle of the 2nd millennium AD in western Africa. Key amongst these
were changes in land use due to the spread and development of agricultural strategies,
which may have had widespread consequences for the climate, hydrology,
biodiversity, and ecosystem services of...
The publication of linked geodata on the semantic web may involve relatively complex operations to map source data to their published version and to link these ones to other datasets. In this paper we propose a technique to provide a compact and abstract description of this process. This technique is based on the use of RDF graph mapping rules that...
In this article, we propose a synthesis of the chronology of Holocene human occupations in the Dogon Country (Mali),
based on 154 radiocarbon dates acquired during the research program “Human population and paleoenvironment
in Africa”. The probability distributions from the calibration of the dates have been summed to produce a curve in
order to vi...
In the Niger Bend, many studies have shown the existence of settlement mounds which mainly developed between the 1st millennium BC and the 15th century AD. While knowledge about tell-type sites in sub-Saharan Africa has advanced in recent years, many aspects of this topic remain poorly understood. Considering the vast geographic area and time span,...
Dans le cadre du projet "Peuplement humain et paléoenvironnement en Afrique", un important cycle de recherches réalisé entre 1997 et 2008 en Pays dogon (Mali) a permis d'établir un profil précis pour le Néolithique récent de cette région, dont le contexte culturel pour l'ensemble de la période holocène demeurait largement méconnu avant les années 1...
La compréhension de l’émergence de l’agriculture en Afrique de l’Ouest a récemment bénéficié d’avancées importantes, mais les mécanismes de sa diffusion rapide au sud du Sahara restent à élucider. La spatialisation des données archéologiques et de leur chronologie radiocarbone permet de visualiser la première expansion des économies de production (...
THE GENERALIZED INCISION OF THE YAME VALLEY (MALI) BETWEEN 2,350 AND 1,700 CAL. YR BP: WHICH PALAEO ENVIRONMENTAL AND ARCHAEOLOGICAL SIGNIFICANCE?
Knowledge on past millennia climate and environmental dynamics are rare in West Africa. Paleoenvironmental studies were mainly conducted from lacustrine records and cover the last African Humid Period, e...
The knowledge of the past millennia climate and environmental dynamics in West Africa is still limited. Palaeoenvironmental studies were mainly conducted from lacustrine records and encompass the last African Humid Period, ending about 5,000 years ago. This paper proposes to reconstruct the palaeoenvironmental dynamics for the period 3,000-1,000 ca...
Although understanding the emergence of agriculture in West Africa has recently benefited from major advances, the reasons for its fast diffusion south of the Sahara remain to be explained. We propose here a reconstruction of African agriculture expansion built from a spatialization of available archaeological data and associated radiocarbon dates....
The emergence and evolution of social complexity remains a major topic in African later prehistory. This paper aims to examine this question in the Dogon Country in Mali by reassessing the chronocultural sequence of Toloy-Tellem-Dogon that was defined 40 years ago. Our discovery of two new sites on the Bandiagara Escarpment with coiled clay tombs (...
In Dogon Country (Mali), recent research carried out in the framework of the international project project "Human Settlement and Paleoenvironment in West Africa" allowed defining a rich chronocultural reference framework for the Late Holocene period (2500-500 cal BC). Covering the regional Late Neolithic/Later Stone Age and Early Iron Age, the sequ...
La grotte du Gardon à Ambérieu-en-Bugey (Ain), au sud du Jura, a fait l’objet, durant plus de quinze années, d’une importante fouille programmée afin d’établir une nouvelle séquence chrono-culturelle de référence pour la Préhistoire récente du haut Bassin rhodanien.
Un premier volume, paru en 2009, présentait le site dans son contexte géographique...

La séquence supérieure de la grotte de l'Abbaye a livré une petite série de sept outils en os, dont trois ont été découverts par J. Reymond lors de ses fouilles réalisées dans les années 1960. L'industrie osseuse de l'Abbaye présente plus d'affinités avec le Chasséen que le NMB au début du 4ème mill. av. J.C. et suggère le développement de particul...
Bayon et al. (Reports, 9 March 2012, p. 1219) interpreted unusually high aluminum-potassium ratio values in an Atlantic sediment core
as indicating anthropogenic deforestation around 2500 years before the present (B.P.). We argue that there is no terrestrial
evidence for forest destruction by humans and that the third millennium B.P. rainforest cri...
The Yamé river, in the Bandiagara Plateau, Dogon Country, Mali, is characterised by extensive alluvial
sedimentary records, particularly in the 1 km long Ounjougou reach where Holocene floodplain pockets
are inset in the Pleistocene formations. These alluvial records have been investigated via geomorphologic
fieldwork and sedimentologic and micromo...

Ce volume constitue le premier volet d'une trilogie présentant les résultats de ces...
New excavations in ravines at Ounjougou in Mali have brought to light a lithic and ceramic assemblage that dates from before 9400 cal BC. The authors show that this first use of pottery coincides with a warm wet period in the Sahara. As in East Asia, where very early ceramics are also known, the pottery and small bifacial arrowheads were the compon...
The international program « Peuplement humain et évolution paléoclimatique en Afrique de l'Ouest » has been developing since 1997 a diachronic analysis of the Man- Environment interactions in the sub-Saharan zone of West Africa. The studies were initiated on the Ounjougou sites complex, on the Bandiagara plateau (dogon country, Mali). This complex...
Une chronologie pour le peuplement et le climat du pays dogon: la séquence culturelle et environnementale du gisement d'Ounjougou (Mali) A chronology for the peopling and the climate of the dogon country: the cultural and environmental sequence of Ounjougou (Mali) Résumé Sur le complexe de sites d'Ounjougou (plateau de Bandiagara, pays dogon, Mali)...
At Ounjougou, a site complex situated in the Yamé River valley on the Bandiagara Plateau (Dogon country,
Mali), multidisciplinary research has revealed a rich archaeological and paleoenvironmental sequence used to reconstruct the
history of human-environment interactions, especially during the Late Holocene (3500–300 cal BC). Geomorphological,
arch...

The sedimentary records of the holocene sequence of Ounjougou are rich in informations. Many onsite missions, laboratory analyses and numerous absolute datings make it possible to propose a reconstitution of the major stages of the hydrosedimentary and paleoenvironmental evolution of the Yamé valley from the start of the Holocene. The geomorphologi...
Si l'apparition de la céramique au début de l'Holocène ancien amorce un tournant
considérable dans les relations entre populations et environnement, de nouvelles et
profondes mutations des modes de vie vont intervenir à Ounjougou au cours de l'Holocène
récent, à partir de 3500 av. J.-c., alors que les conditions climatiques se dégradent peu à peu
