Land recycling in Europe. Approaches to measuring extent and impacts

Land take, or the change from non-artificial to artificial land cover, reflects on-going and often conflicting claims on land. Some of the land that is 'taken' for urban development is covered with an impervious surface, which severely hampers ecosystem functioning and the related delivery of ecosystem services.
However, when land is 'recycled', land that was developed in the past and has become available for redevelopment again is reused. Urban densification, or infilling, can also prevent the consumption of land that may be very valuable for food production or recreation. In this report, the processes of recycling and densification are jointly referred to as 'land recycling in its broad sense'. Land recycling can be considered a response to the on-going pressures we as a society apply to our land resources, particularly in the urban fringe. The recognition that our land resources need conservation is articulated in the EU's Seventh Environment Action Programme (7th EAP). The 7th EAP also recognises the need to improve the knowledge base.
