Protecting the natural spaces on the edge of the Paris metropolis. Guide plan for the development of the natural space 'Joncs Marins' in the Paris metropolis

Christian Horn


The site of the 'Joncs Marins' is situated on the southern edge of the Paris metropolitan area. It is a natural open space with woodlands, meadows and farmland and part of the river Orge valley. Different uses like agriculture, industrial and commercial activities and recreation coexist in this space alongside legal and illegal housing constructions.
As the urbanized area of the Paris metropolis is growing, these natural spaces are increasingly under the pressure of urbanisation. Recognizing the importance of these spaces, the regional government tries to preserve them from an ongoing fragmentation. The planning office Rethink got commissioned by the region to elaborate a guide plan for the protection and future uses of the Joncs Marins. A guide plan, that would compose the
basis to coordinate the future initiatives of the local actors.
Today situated on the edge of the metropolis, these natural spaces will form the future urban parks, when the urbanisation has overgrown them. Like the two major parks of Paris, the 'Bois de Boulogne' and the 'Bois de Vincennes' have been once woodlands for hunting situated far outside of the city.
