Climate change and geomorphological dynamics of the Breton coasts. Lessons for responsible management of the intertwining of spatial and temporal scales
In France, the strong storms of recent decades and their impact on coastlines have led to the emphasis being placed on the causal links that may exist between climate change and the current trends in the coastlines subject to erosion and submersion. However, it seems necessary to put into perspectiv...
Education for sustainable development
'pbIn 2010, the National Sustainable Development Strategy (NSDS) did not hesitate to recall that “education for sustainable development should prepare the future citizen to understand, integrate the complexity of relations between social, economic, cultural and environmental issues and act”/emb. Edu...
Accessibility and space-temporal discontinuities in the North — Pas de Calais
As part of the discussions on regional and intra-regional divisions, this proposal calls for a multi-scalary spatial and temporal analysis to question the functional coherence of the Nord — Pas de Calais region and its employment areas (INSEE definition). The aim is thus to reveal, on a number of sc...
"Coquillages et crustacés" : spatiotemporal dynamic of freshwater metacommunities
Species communities vary as a result of many processes: filtering of species by environments, interspecific interactions, dispersal, and stochastic processes. Empiricists often try to evaluate their respective roles based on the traces they leave on the spatial structure of communities. Unfortunatel...
Characterization of coarse sediment particle : experimentation, development and in situ applications
The influence of fluvial systems dynamics on riverine landscape patterns is the consequence of complex ecosystem dynamics. These driving factors can be analysed at different spatiotemporal scales of the fluvial system (for example: river basin, functional units, alluvial megaforms or sedimentary par...
Measuring inequalities in mobility and access to the steering wheel.
introduction. 1 the continuous improvement of mobility conditions for several decades has been accompanied by major changes in the spatial and temporal scales of economic and social life. Individuals now have a reticular relationship with the territory: they live in one place, work in another, disco...
Biogeographical approach to landscapes: vary temporal and spatial scales to better understand current landscapes. Example of the Domaine National de Chambord
National audience When the biogeograph looks at current landscapes, the question arises as to the choice of scale, both spatial and temporal. “Question of scale: Time and space” is thus a central topic in the methodological approach to landscapes conducted by this researcher. In this proposal, we pl...
A systemic approach to the functioning of a bocager agricultural area
‘titrebSummary’/titreb. article presents a systemic approach to the functioning of woodland with environmental challenges. After studying past and current spatial and temporal dynamics of landscapes, identifying and prioritising the factors explaining the changes observed, this approach highlights t...
Reconstructing the evolution of forest landscapes
Apprehending the development of a forest area means crossing time and space. It gives a temporal dimension to an object that is semi-natural or man-made, and to consider that this object can be geographically moving. As part of the applied research approach to which this study relates (reforestation...
Couplage de SMA avec des EDO pour simuler les phénomènes écologiques à grande échelle
national audience The explicitly spatial modelling is essential in ecology for decision-making and management. It involves modelling the heterogeneity of the landscape and the fact that different species of agents may behave at different scales, which increases the need for data, and requires their...
GrAPHiSTAn exploratory analysis approach for the identification of dynamics of spatio-temporal phenomena.
Datasets allowing the description of spatio-temporal phenomena are becoming ever more numerous. These new data can be very different from those usually observed for studying spatio-temporal phenomena. An analysis through a hypothetico-deductive approach, like is mainly done in statistic and GIS doma...
The price of the city. The housing market in the metropolitan area of Marseille (1990-2010)
La France a comme beaucoup de pays de l’OCDE connu une très forte inflation immobilière ces quinze dernières années. La hausse des prix a été particulièrement prononcée dans l’aire urbaine de Marseille-Aix-en-Provence, mettant en relief les limites des catégories et des méthodes d’analyse des marché...
Perception of the tree in the Sahélian context
In the context of the OHMi — Téssékéré and the ANR Future Sahel, research is being conducted on the uses of trees as a provider of resources and vectors of ecosystem services for local actors. Depending on the degree of isolation of the areas covered by the study, but also of accessible botanical sp...
Time, art and cartography. Representing worlds and societies on the move
At a time of continuous information, we have never experienced such distant, heterogeneous and irreconcilable times. At the same time, spaces and times followed a break-up, a disjunction combined with a new time lag. In this “hypermodern” society, time has become a central entry point in the observa...
Stochastic data mining for understanding the temporal and spatial dynamics of agricultural territories. Contribution to a digital agronomy of territories
Agriculture is the human activity that uses and transforms most of the land surface. Its intensity and standardisation have led to a number of environmental and environmental problems. Understanding the past and current dynamics of agricultural areas at regional levels, compatible with the levels at...
Stochastic data mining for the understanding of temporal and spatial dynamics in agricultural landscapes. Contribution to a numerical landscape agronomy
The purpose of this thesis is to develop a generic method for modelling the past and current dynamics of Landscape Organization of Farming Activity (LOFA). We developed a stochastic modelling method based on Hidden Markov Models that allows data mining within a corpus of spatio-temporal land use dat...
Vulnerability and resilience to climate change in urban settings: towards new strategies for sustainable urban development?
report on the heightened forms of risks to urban areas and urban societies related to climate change and their impacts, the objective of this research proposal is threefold. Firstly, this project has a dimension of theorising and conceptualisation with a view to better defining and characterising in...
PH. Bakery, 2002, La France: space and time. Summaries, dissertations, comments of documents
In the collection led by B. Dumortier, Ph. Bakery gives us a good test of the original titles. It successfully attempts to connect territories combined at various scales with the long, disruptive and continuous times that have shaped the landscapes of the Hexagone, created the identity of a nation t...
Multiscalary analysis of local aerology in the Caennese region
Due to its coastal situation, the Caennese region is regularly subjected to sea and earth breezes during the summer period. In order to understand this phenomenon, we relied on existing documents and data (Météo France) and on an original database set up during field campaigns carried out in 2003, 2...
