Dynamique des paysages et potentiel écologique de la région Franche-Comté (D2PE)

Le chantier D2PE a pour objet d’analyser les changements d’occupation du sol intervenus pendant les dernières décennies en Franche-Comté, résultant de l’étalement urbain, la densification des réseaux de transport et des mutations agricoles. L’impact de ces changements sur le paysage est examiné dans deux dimensions différentes : une dimension visible et esthétique, en rapport avec la qualité visuelle du cadre de vie résidentiel, et une dimension écologique, en lien avec la fonctionnalité des habitats de la faune sauvage. Par cette étude, le chantier a une ambition méthodologique puisqu’il s’agit de mettre en place et valider une approche de modélisation spatiale. Cette étude s’applique à zo…

Le paysage, entre esthétique & écologie : modélisation rétrospective à partir de changements d'occupation du sol

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 areusually studied within different disciplines, little research has been done into how the two clashor 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 usingspatial metrics based on land-cover data. It focuses on changes in the urban fringes of two French cities (Paris and Besançon) over th…

Exploring individual preferences for periurban landscapes

International audience; Landscape aesthetic quality has recently become an important dimension of land use policies since it is likely to play a role in human well-being. Several scientific studies have shown that landscape is a significant component of residential satisfaction of inhabitants in urban and suburban areas (Hur & Nasar, 2010; Kweon et al., 2010). Although neglected by land-use planning for decades (Gallent et al., 2004), urban fringes are particularly interesting for analyzing landscape changes. These spaces where town meets countryside (Scott et al., 2013) are indeed particularly concerned with urban sprawl that occurs in all European cities from 1960s (EEA, 2006). Such chang…

A Multi-Scale Analysis to Measure Ecological Impact of LUCC in a Built Environment

International audience; In human-dominated environments, efforts to preserve ecological connectivity between animal species habitats is an important issue. These areas are indeed concern by anthropogenic pressures leading to rapid land use and land cover changes (LUCC). This is particularly the case of urban fringes, affected by many changes (e.g. urban sprawl) specifically for several decades.Of all the methods to model the ecological networks connectivity, landscape graphs provide a relevant approach, which interest for decision support in land-use planning has already been highlighted (Foltête et al., 2014). This approach allows to represent ecological networks in a simplified way as gra…
