Imperviousness and imperviousness change in Europe

Imperviousness negatively affects biodiversity, carbon storage and sequestration, soil hydrological properties, ecosystem services and nature conservation. In 2018, the sealed area in the European Union Member States was 110,702km 2 (2.7%). The increase in this area was 3,606km 2 (3.4%) between 2006 and 2018. The largest sealing increase of 1,156km 2 during 2009-2012 fell to half during 2012-2015, yet picked up again from 2015 to 2018 (796 km 2 ). Although most sealing happened in settlements, sealing in cropland was also substantial with 1,383km 2 agricultural area sealed from 2006 till 2018.

Imperviousness increase by land use category in EU-27

The chart shows the increase in imperviousness surfaces for each land use category in the EU-27 region every 3 years between 2006 and 2018. The Y axis shows the increase in km 2 and the labels inside the figure indicate the imperviousness increase compared to the sealed soil surface at the start of the period, in percentage.
