Despite all the planning, the Netherlands has plenty of places temporarily without planned use, such as gravel quarries, abandoned army-practice areas, sand dumps and landfill sites. They can be found in a landscape in transition, for example the sand flats of the Maasvlakte, an artificial peninsula near Rotterdam that will soon be turned into a harbour. And the production forests in North Brabant which are slowly being transformed into nature reserves.
The chunks of landscape are used for what are often rather ill-defined leisure activities that try to benefit from the temporary status and the specific artificial landscape features.
These sites are not usually programmed or described as public space, but when people occupy an empty landscape this can be considered as an initial, transient programming process, after which the authorities start to impose rules and unrestricted public use ends.
