Biodiversity and urban planning

Abstract

Biodiversity is defined by the richness in species, genes and ecosystems but also and especially by their interrelations, i.e. the system functioning. To develop biodiversity, this functioning requires considering both different types of species and different scales of processes, including the global scale of the territory (dispersion of individuals). In town, the ecological services provide by biodiversity are fundamental to urban sustainability. An urban planning paradigm shift must register geography and functional ecology in diagnostics, as well as mobility for example. Consequently, the non-built areas could have an important meaning as building and the ecology of areas could be considered at the same level as architecture.
