This thesis is based on the challenges of assessing the impacts of urban planning decisions in the light of the imperatives of sustainable development. Beyond the vagueness often emerges from this concept, it is here to conduct a reflection on a balance to be found between the three pillars identified about sustainable development: economic, social and environmental. The aim is to consider how to assess the impacts of development policies in each of these three pillars and what conclusions should be drawn from them? The aim here is to provide answers by assessing the performance of the territories studied in these three pillars of sustainable development. For this purpose, the work is based on simulation models (here the MobiSim model developed within Laboratoire ThéMA) and on the production of synthetic indicators allowing a readable analysis and evaluation of the space. The combination of these synthetic indicators makes it possible to visualize and analyze the sustainability of the territory studied and to deduce the measures to be implemented with a view to ensuring a sustainable development policy. It is a question of putting the methodology and the results obtained into perspective in a global vision, seeking to establish by the balance between the three pillars a harmony which allows to satisfy the objectives of a policy guided by the imperatives linked to the concept of inherited from the Bruntland report. A critical approach to this concept and an analysis of the sets of actors of a territory are here conduits in order to be able to implement the scientific research work within a decision-making process. The challenge is to allow the results of research based on power modeling tools to find a more concrete and operational problem.

The interaction between space and network are frequently questioned in the academic literature, by asking the economical and demographical impacts of a new infrastructure, often studied at the scale of a project. This work aims to investigate the components of the interaction in both large spatial and temporal scales. The hypothesis is that the temporal depth and the national scale could bring new explanations. This work is based on the collect, the exploitation and the analysis of the large spatio-temporal database FRANcE (French Railway Network). It identifies all sections of the network since the 19th century and the population census. This database also contains the traces of the speed, which are novel information for network, and allows the accessibility to become a decisive variable in the explanations.

Rather than acquisition new data with an intensive phase of collect, we aim to build a methodological chain to study the two senses of interaction between space and network. It requires the adaptation of data structuration and analysis. The approach of this thesis consists on the growing modelling of the phenomenon, from the comprehension to formalization of data to the analysis, which requires the use of other disciplines. This work uses the graph theory to investigate the two senses of the relationship. It permits to study the network effect in the long run by diversifying the data to identify spatial and temporal ranges. It permits to study the impact of a pre-existing structure in the morphogenesis of the network, by using a dynamic model of network evolution, between diffusion and hierarchical organization. This work aims to understand the link between space and network, where the methodological tools can be adapted to other networks, other times and actual questioning.

Landscape is both a backdrop to the lives of human populations and a medium for the life cycle of animal species. Landscape changes induced by land-use and land-cover dynamics affect both these dimensions, the one aesthetic, and the other ecological. Because these rationales are usually studied within different disciplines, little research has been done into how the two clash or combine as and when landscape structures change. This work seeks therefore to model the spatial co-evolution of the aesthetic and ecological functions of landscape retrospectively using spatial metrics based on land-cover data. It focuses on changes in the urban fringes of two French cities (Paris and Besançon) over the last 30 years.

The approach attempts first to use land-cover data to model (1) the landscape preferences of a set of individuals and (2) the ecological connectivity of a set of animal species. Drawing on both multivariate statistical analysis and spatial analysis, the core of this work consists in investigating how the two functions have evolved in convergent or divergent ways over time. The results provide fresh insight into the relationship between landscape aesthetics and landscape ecology and raise questions about the value of spatial modelling for a landscape management approach that endeavours to reconcile the preservation of residents’ living environments and the conservation of biodiversity.
