Urbanization in the EU: past, present and future


Urbanization dominates the EU landscape, causing specific problems to ecosystems and biodiversity. Urban sprawl has accompanied the development of towns and cities across the EU over the past 50 years, with cities expanding their area by 78 per cent on average, while the population has grown by only 33 per cent. The dense enclosed quarters of the compact city model have been replaced by free-standing apartment blocks, semi-detached and detached houses, with more than a doubling of the space occupied per inhabitant over that period. On a straight extrapolation of current practices, a 0.6 per cent annual increase in urban area, although apparently small, would lead to a doubling of the total amount of urban area in a little over a century (EEA 2005). Residential urban areas have expanded at four times the rate of population growth, while industrial and commercial areas have grown more than seven times as rapidly since 1990 (EEA 2015g ; EEA 2013c). The EU goal of no net land take by 2050 must be met by designing a future urban environment with broad public appeal, developing a green infrastructure within urban zones of planned networks of natural or semi-natural areas managed to deliver a range of ecosystem services (EEA 2013g). With high levels of urbanization, energy demands continue to rise, bringing increased demands on land for renewable energy production and distribution, leading to conflicts of interest with the conservation of biodiversity and natural habitats (Hastik et al. 2015; Gove et al. 2013).


55: Overexploitation of forest resources


With a long-standing tradition of forestry and forest management, deforestation is no longer a threat for the region as a whole, and many forest areas, especially in Western and Central Europe appear stable. Still, unsustainable forest management, in combination with increased fragmentation and the effects of climate change, pose threats to forest biodiversity, particularly in parts of Central, Eastern, and South Eastern Europe, the Caucasus and Central Asia, and overexploitation of forest resources remains a significant pressure. Even where wood harvesting in EU is largely sustainable, dead wood – which is an important substrate for entire guilds of invertebrates and fungi – remains well below optimal levels in most forests.


On average, annual wood harvests for 24 countries representing 96 per cent of the forests in EU, are significantly under the annual mean level of growth (UNECE and FAO 2011). The total growing stock of European forests adds up to 114.2 billion cubic meters, with 96 billion available for wood supply. Growing stock in these has expanded by 8.6 billion cubic meters over the past 20 years (Table 7) representing an annual average of 0.39 per cent during this period. This assessment may however be hiding a more precarious situation for biodiversity, particularly as the data do not cover all the biodiversity hotspots of the pan-European region, particularly the Caucasus, Iranian-Anatolian zone and the mountains of Central Asia, where forests are still threatened. Large tree diameters and over-mature stands are not favoured in managed forests, so forests in the EU are largely even-aged and between 20 and 80 years old.
