To provide high-quality natural spaces for its residents, the district of Ris-Orangis (Essonne) is implementing a number of projects, from the No Net Land Take experiment to the allotment gardens provided to individuals for pesticide-free vegetable growing. This working-class district in the greater Paris suburbs has an ace up its sleeve: large industrial and agricultural brownfield areas. The pressure to build housing is strong but there is still an opportunity to create a modern town connected to the living world.
