of urban development, sometimes referred to as ‘sprawl without growth’ (see Nuissl and<br />

Rink, 2005; Schmidt, 2011) is a somewhat new phenomenon in the developed world and it<br />

is still not well understood. Only in some countries, like Ireland or Spain, does population<br />

growth seem to be an important driver of urban growth. Furthermore, our data shows that<br />

economic growth cannot fully explain the variability in land-consumption dynamics either<br />

[ gure 6(b)]. Obviously, some countries were able to manage the impact of economic<br />

growth on land consumption (eg, Estonia/Lithuania, Poland) with a surprisingly low<br />

amount of urban expansion while others experienced relatively low GDP growth rates but<br />

high levels of urban growth (eg, Portugal in the 2000s).<br />

Second, we assume that—at least to some extent—the national urban system can<br />

explain variations in spatial patterns of urban growth across countries. In countries that are<br />

demographically and economically dominated by their capital city or a few large cities urban<br />

growth occurred mainly clustered in central areas. This applies to countries like Austria,<br />

Ireland, Latvia, and the United Kingdom. In contrast, countries with a rather polycentric<br />

urban system such as Denmark, Germany, Italy, and the Netherlands experienced a more<br />

evenly distributed pattern of urban expansion. Closely corresponding to that, we also found<br />

different trends towards concentration and deconcentration of urban growth over time. In the<br />

majority of East European countries the legacy of socialistic housing policies is still visible<br />

in the form of above-average urban densities and a concentration of urban functions. Our<br />

data show that urban sprawl in these countries occurs around a few concentrated islands and<br />

axes of growth, which is in line with recent studies that report growing regional disparities<br />

in income levels and economic growth for most of the new member states of the European<br />

Union (Landesmann and Römisch, 2006; Molle, 2007). The opposite can be attributed to<br />

many West European countries where suburbanisation and counterurbanisation processes<br />

(Champion, 2001) resulted in a more decentralised and land-consuming pattern of urban<br />

growth.<br />

Third, the administrative system and the public control over land-use change might be<br />

another potential causative factor explaining the spatial pattern of urban growth. As mentioned<br />

in section 2, many scholars claim that the institutional fragmentation of responsibilities for<br />

land-use planning favours urban sprawl. Germany’s spatial planning system—for example,<br />

is characterised by decentralised land-use governance with numerous local authorities<br />

controlling urban land use. This is likely to promote urban sprawl as it increases the number<br />

of jurisdictions seeking extrabudgetary revenue through land conversion to urban uses.<br />

The size of local government units may also be important in other ways—larger entities<br />

may be less reliant on any one particular investor or project, and less vulnerable to the in uence<br />

of individual landowners. In Germany and in countries with similar land-management systems,
