There’s no way around it: all construction has a direct impact on the soil. Depending on the extent of the changes brought about by construction, it can completely or partly destroy vital soil functions. For example, paving over open space destroys natural habitats. Land use resulting in drastic changes in both greenfield land and farmland can be curbed, however.

Paving over large areas, particularly in urban environments, creates an urban climate whose air temperatures are higher than those found in forests and greenfield sites. Such areas also prevent groundwater formation, since precipitation runoff ends up in sewer systems rather than being absorbed by the soil.
Uncontrolled loss of naturally developed soil results in habitat and landscape fragmentation, and in a permanent loss of spatial corridors, particularly for native fauna. Currently, some 80 hectares per day of open space is used for construction or other purposes. And while this figure is slightly lower than in the past, it is still very far from the government’s goal of reducing land use to 30 hectares per day by 2020.
Bodenversiegelung - Wie wir uns der besten Flächen berauben
Straßen und Parkplätze versiegeln den Erdboden, sodass dieser immer weniger CO2 aus der Atmosphäre aufnimmt. Oft gehen dadurch auch landwirtschaftliche Flächen verloren, die vorher Menschen mit Nahrung versorgt haben. Green Radio hat mit Jean Charles Munch, Direktor am Institut für Bodenökologie des Helmholtz-Zentrums München über dieses globale Problem gesprochen.
The impact of climate change will be felt more strongly in the future – and in Germany too. This is the conclusion reached in what is called the vulnerability analysis, a comprehensive study on Germany's vulnerability to climate change.
