Protective defence structures (fortified ramparts) have long since lost their function. Under the influence of more intensive mobility, technology and the declining economic importance of the surrounding agricultural lands, the boundary between city and landscape has become diffuse. New freedoms and possibilities have resulted in an erosion of the contemporary city and of the urban potential. the cities of the netherlands have undergone explosive growth and have ‘spilled over’ an enormous amount of space. Amsterdam, for instance, grew from 15 km2 to 200 km2 over the last 100 years, while its population grew by a mere 50 per cent (from 500,000 to 750,000 inhabitants). Had density remained constant, 22.5 km2 would have sufficed. The figures in the illustration below clearly show that per capita use of space, directly or indirectly, is responsible for an expansion of the urban area by a factor of 6. 70% a century ago: 5 people per dwelling short cross sections, limited view (unilateral orientation), shallow dwellings on narrow streets 1900 50% today: 2.3 people per dwelling long cross sections, open views (bilateral orientation), deeper dwellings on broader streets 2000 simply put, half as many people live in homes three times as large as a century ago. when, on top of that, these homes are situated on twice as much land, this produces 2 × 3 × 2 = 12. Finally, the population of the Netherlands has increased substantially. Whereas a little more than six million people lived in this country at the start of the twentieth century, the Dutch now number 16 million. All this means the use of space increased by a factor of 32 during the past century, explaining the evolution of cartographic data for the Netherlands over the last 100 years. cities full of space 17 1990 1992 1994 1996 1998 2000 2002 2004 2006 200 180 160 140 120 100 80 60 40 20 0 m2 rental m2 owner occ total m2/occupant content and dwelling occupancy of new-build housing (source: cbs, leiden) CitiesfullofspaceENG.indd 17 03-12-2008 21:45:3
