Dépôts de bronzes et relations visuelles autour du Camp du Château à Salins-les-Bains (Jura, France) à la fin du Bronze moyen et au début du Bronze f…

2017

Systematic field surveys have been carried out in the surroundings of the Camp du Château near Salins-les-Bains for several years. These investigations led to the discovery of forty-odd hoards dating mainly from the end of the Middle Bronze Age and the beginning of the Late Bronze Age. The good accuracy of their localization allows us to study how they were integrated into the landscape. Their positioning suggests that the choice of location favored topographical criteria. We are interested in the question of intervisibility between the place of hoarding and the remarkable points of the natural and social landscape, especially the hill-forts. The results of GIS analysis show the constitutio…

Fossilized Bronze, Invisible Bronze

2023

The systematic field surveys carried out since the beginning of the 2000s around the fortified site of the Camp du Château at Salins-les-Bains (Jura, France) have led to the discovery of 74 Bronze Age hoards, a density rarely observed in France. Dating from the beginning of the Middle Bronze Age to the Late Bronze Age, this dataset is unique as it provides detailed information on the composition of the hoards and their distribution within a defined territorial and chronological framework.These hoards are mainly made up of fragments, as around 90% of the objects are broken. This is deliberate and seems to correspond to a codified ritual of destruction which could be related to the notion of …

Potential predictability of crop impacting climate variables for East Africa and application to sorghum in the Mt Kenya area

2013

In Southern countries with rural low income populations, the vulnerability of rainfed agriculture to rainfall variability requires effective solutions to mitigate the effects of climatic hazards on crops. Predicting the characteristics of rainy seasons some time before they start should help the establishment of agricultural adaptation strategies to rainfall hazards. This is the objective of the present study, focused on East Africa (Kenya and northern Tanzania), and divided in three parts:- Define and document intra-seasonal descriptors (ISD) that will be considered in the predictability study. A new methodological approach has been developed in order to define the onset date (ORS) and the…

Génétique des textes et système chaotique

2016

Textual genetics and chaotic system Although we share Louis Hay's idea that it is impossible to homologate and systematize the operations which can be observed in manuscripts, it is however possible to interpret whatever creation process in terms of the passage from entropy to order. The possibility of an analogy between text and chaotic system had been advanced by Noëlle Batt according to whom each work actually satisfies the principles of the chaotic system. It is starting from such principles that we will try to show the analogy between chaotic system and textual genetics: 1. The fact that we are dealing with an evolving system (with variables and permanent features) endowed with a tempo…

Spatial coherence and potential predictability of intraseasonal descriptors of the rainy season in Soudano-Sahelian Africa : application to the pearl…

2010

The aim of this thesis is twofold : (i) fill a lack of knowledge about the spatial coherence and seasonal predictability of the intraseasonal characteristics (ISC) of the soudano-sahelian rainy season. These ISC are the seasonal rainfall amount (S), the daily rainfall frequency > 1 mm (O), the daily rainfall mean intensity (I), the dates of the onset and withdrawal of the rainy season, the mean length of the dry (LDS) and/or wet spells (LWS) ; (ii) document the climate-agriculture relationship over the Niamey area based on the millet crop example.From FRIEND-AOC daily rainfall records (1950-2000) for a 136 stations-network located in Senegal, Mali, Burkina-Faso and Niger, the spatial cohere…

Évaluation des préférences esthétiques du paysage à l’aide de métriques de visibilité. Application aux franges urbaines d’Île¬de-France

2015

National audience; La qualité esthétique du paysage jouant un rôle dans le niveau de bien-être des individus, le paysage est récemment devenu une dimension importante des politiques d’aménagement du territoire. La Convention européenne du paysage (ELC), adoptée en 2000 par le Conseil de l’Europe, définit le paysage comme « une partie de territoire telle que perçue par les populations, dont le caractère résulte de l’action de facteurs naturels et/ou humains et de leurs interrelations» (Conseil de l’Europe, 2000). Cette convention, qui met l’accent sur l’expérience humaine du paysage, souligne l’importance de sa protection, de sa gestion etde son aménagement.

Diagnosis and predictability of intraseasonal characteristics of wet and dry spells over equatorial east Africa

2010

Most of Eastern Africa has arid and semi-arid climate with high space-time variability in rainfall. The droughts are very common in this region, and often persist for several years, preceded or followed by extreme floods. Most of the livelihoods and socio-economic activities however remain rain-dependent leading to severe negative impacts during the periods of occurrence of climate extremes. It has been noted that one extreme event was capable of reversing national economic growth made over a period of several years. Thus no sustainable development can be attained in eastern Africa without effective mainstreaming of climate information in the development policies, plans and programmes. Many…

On the emergence of the urban phenomenon. Part I

2001

In this paper we develop a relatively simple but general model describing the formation of urban agglomerations in a pre-industrial setting. Rural agglomeration on a local scale arises from the multiplication and specialization of intermediate goods and labor services, while dispersion is due to the commuting costs of agricultural workers. Urban agglomeration on a more global scale stems from the trade-off between increasing returns to scale and transport costs of goods. We derive a general equilibrium model of the formation of urban structures and show how population growth, strict indivisibilities and structural changes in the production sector can modify quantitatively and qualitatively …
