Since 2008, the regional agency for biodiversity in Paris region (ARB Île-de-France) aims at involving local actors to act on biodiversity issues, particularly in terms of knowledge and regarding actions in urban planning, agriculture or construction. The decline of biodiversity in urban areas invites us to imagine innovative solutions to manage, build, renovate and promote biodiversity in urbanism and architecture. Solutions exist on every scale. To better understand these solutions, we produced the video "Urbanism, architecture and biodiversity : when nature inspires cities and buildings". It is made to provide cities, architects, land planners or the building sector with solutions to develop green infrastructure and solutions for eco-cities and eco-buildings.
