Economies d'agglomération et configurations spatiales dans les espaces ruraux
1997
The question to be addressed here is that of the agglomeration/dispersion forces that are likely to account for the location of people and jobs in rural areas and the way they explain spatial patterns in rural areas depending on urban influence. Economic geography models may provide suitable tools with which to investigate the organization of rural areas. We first review these models, focusing on dispersion forces, which rest basically on land consumption and transport costs. We suggest then a set of hypotheses concerning the main forces at work in rural areas. Intensity of agglomeration economies is hypothesized to be related to the urban size, which in turn induces increasing land rents a…
La spiritualité des officiers royaux au début du XVIe siècle : Antoine Robert, bourgeois de Paris et secrétaire du roi de Louis XI à François Ier
1977
Antoine Robert, clerk of the high judicial court in Paris during the reign of Francis 1st, was one of the oldest royal secretaries when he died in 1521, on September. He is known to have given all his personnal assets and properties to the benedictin convent of the Blancs-Manteaux in Paris. His religious behaviour can be studied through three documents relating to his will, foundation and inheritance. So Antoine Robert, rather a rich and well educated laic seems to corroborate the weight of ideas which were brought from Flanders into France by the " Frères de la vie commune " and developped during the Reformation. The biblical and ancient authors' quotations contained in his will show that …

Human capital and RD Driven Growth: analyse for France at regional level on the long run
2012
At the root of the Lisbon goal, for Europe, is placed the awareness for advocating a close link between growth and dissemination of advanced knowledge and innovation, on the one hand, and raising in general endowments in human capital, on the other hand, as to have power over the development of non-specific skills and boost efficiency. Much work in literature also stressed the interest of the position concerning traditional activities in the geography of innovation and links, in the long term, between the spatial distribution of longestablished skills and knowledge creation. Following Jones, in this approach, for which contribution to R&D and innovation explains half of the increase in weal…
La résilience : un concept pour la gestion des risques
2007
Les systemes socio naturels possedent la capacite de resister aux aleas. Les catastrophes les perturbent, mais les font rarement disparaitre. Le concept de resilience, d’origine physique, qui illustre cette capacite s’est enrichi lors de son transfert dans differentes disciplines scientifiques. Certes, la resilience est difficile a mesurer. Mais sa connaissance permet d’adopter de nouvelles formes de gestion des risques naturels ou sociaux. Ces nouvelles formes de gestion sont tres differentes des approches technologiques qui ne sont pas toujours bien adaptees au milieu ou a la societe.
Le territoire comme un système complexe : un concept opératoire pour l'aménagement et la géographie
2006
International audience; Les territoires sont aujourd'hui sur le devant de la scène, pressés de fournir des solutions de développement socio-économique, ou une image cohérente des lieux qu'ils englobent. On assiste à une forte consommation du concept, tout est territoire ; et des concepts qui recouvrent d'autres réalités glissent imperceptiblement vers cette boîte noire qui représente tout et rien à la fois. Visitons le concept sous l'angle de la systémique afin de produire une définition opérationnelle qui permette de resituer le territoire vis-à-vis de l'espace géographique. Le territoire défini se trouve ainsi replacé au cœur de la complexité.
Fractal dimension versus density of built-up surfaces in the periphery of Brussels
2007
International audience; This paper aims at showing the usefulness of the fractal dimension for characterizing the spatial structure of the built-up surfaces within the periurban fringe. We first discuss our methodology and expectations in terms of operationality of the fractal dimension theoretically and geometrically. An empirical analysis is then performed on the southern periphery of Brussels (Brabant Wallon). The empirical analysis is divided into two parts: first, the effect of the size and shape of the windows on the fractal measures is empirically evaluated; this leads to a methodological discussion about the importance of the scale of analysis as well as the real sense of fractality…
Influence of the regional landscape connectivity on the location of roe deer roadkill hotspots
2016
International audience; Linear infrastructures threaten ecosystems and have both direct and indirect effects on ecological habitats and individuals. The fragmentation effect (i.e. splitting or loss of habitat patches) and the barrier effect (i.e. fences, traffic noise avoidance, and roadkill) are widely reported. Wildlife-vehicle collisions are the most visible direct effect and can result in severe human injuries. In Europe, the roe deer population is growing and roe deer roadkills are becoming more common. Roe deer movements depend on landscape features and regional-scale connectivity. Here, we investigate the influence of the landscape network on the location of roe deer roadkill hotspot…
Capability of a high resolution hydroclimatic modelling chain to simulate soil water deficit indices for Douglas-fir and common Beeches over Burgundy.
2016
During the 2003 drought and heat wave event, douglas-fir and common beech stands in Burgundy have been heavily affected, and presented symptoms of dieback and mortality. This event seems to be the first occurrence of expected climatic changes in the near future and questions their sustainability in Burgundy since their climate vulnerability is mainly due to the amplitude and accumulated water constraints exercised during their growing cycle. In the context of climate change and in order to provide information to forest managers who partly rely on a mapping of the climatic constraints until the end of this century, this work explores the ability of a high resolution hydroclimatic modelling c…
