Land recycling addresses the reuse of abandoned, vacant or underused urban land for new developments within FUAs (Functional Urban Areas, i.e. urban agglomerations). Land recycling is considered a response to land take within FUAs, i.e. urban development on arable land, permanent crop land or semi-natural areas. It is a key planning instrument for achieving the goal of no net land take by 2050 (EC, 2016).

The intensity of land take is calculated as land take in the given period in % of artificial surfaces in the year 2000. For easier comparability land take is summarized within NUTS3 regions.
The raster file is the basis of the indicator for assessing landscape fragmentation due to urban and transport expansion. The computation is based on the method of Effective Mesh Density (seff). The Effective Mesh Density (seff) is a measure of landscape fragmentation, i.e. the degree to which movement between different parts of the landscape is interrupted by a Fragmentation Geometry (FG). FGs are defined as the presence of impervious surfaces and traffic infrastructure. The Effective Mesh Density gives the effective number of meshes (or landscape patches) per 1000 km2, in other words, the density of the meshes. The more FGs fragment the landscape, the higher the effective mesh density. The seff values are reported within the 1km sq regular LEAC grid.

Land recycling is still low in all European countries: on average, land recycling accounted for only 13.5 % of total land consumption in European cities in the 2006-2012 period.
The land use densification process, i.e. when land development makes maximum use of existing infrastructure, accounts for the largest proportion of land recycling (10 % of total land consumption). However, in most countries, land take dominates over densification in total land management with the exception of Finland and France.
Grey recycling, i.e. internal conversions between residential and/or non-residential land cover types, is secondary to densification, ranging from 14 % to less than 1 % of total land consumption. Land take predominates over grey recycling in total land management in all countries.
Green recycling, i.e. the development of green urban areas using previously built-up areas, is an important trend that reverses soil sealing, but it is a marginal process in all countries and, on average, it accounts for only 0.2 % of total land consumption.
The high resolution imperviousness products capture the percentage and change of soil sealing. Built-up areas are characterized by the substitution of the original (semi-) natural land cover or water surface with an artificial, often impervious cover. These artificial surfaces are usually maintained over long periods of time.
A series of high resolution imperviousness datasets (for the 2006, 2009, 2012 and 2015 reference years) with all artificially sealed areas was produced using automatic derivation based on calibrated Normalized Difference Vegetation Index (NDVI).
This series of imperviousness layers constitutes the main status layers. They are per-pixel estimates of impermeable cover of soil (soil sealing) and are mapped as the degree of imperviousness (0-100%).
Imperviousness change layers were produced as a difference between the reference years (2006-2009, 2009-2012, 2012-2015 and additionally 2006-2012, to fully match the CORINE Land Cover production cycle) and are presented 1) as degree of imperviousness change (-100% -- +100%), in 20m and 100m pixel size, and 2) a classified (categorical) 20m change product.

Large parts of Europe are highly fragmented because of transport infrastructure and urban expansion.
The Atlantic and Continental biogeographical regions show by far the highest degree of fragmentation in Europe. Around 50 % of the Atlantic region and 40 % of the Continental region are highly fragmented. The area with the lowest fragmentation covers less than 10 % of these regions. In the Alpine, Macaronesian and Arctic biogeographical regions, less than 3 % of the area is highly fragmented.
The Benelux countries are the most fragmented in Europe. In Luxembourg 93 % of the country is highly fragmented, while in Belgium the figure is 80 % and in the Netherlands 67 %. In eastern European countries, in the Mediterranean and in Ireland and Scotland the fragmenting pressure of urban and transport expansion is considerably weaker.
Around 35 % of the cultivated areas, almost 30 % of grasslands and around 12 % of forests are under great fragmentation pressure. In contrast, close to 50 % of the area covered by mires, bogs, fens, heathland, scrub and tundra ecosystems are under low pressure by fragmentation. The forest ecosystems in the Alpine region are under the lowest pressure from fragmentation in Europe.
All over Europe and in all the biogeographical regions, the fragmentation pressure is lower inside Natura 2000 sites than in their surrounding areas.
Although cities and strongly populated areas are generally most fragmented in Europe, 50 % of sparsely populated regions e.g. in France and the Netherlands, are under great fragmentation pressure as well.

The map shows the density of soil sealing in 2012, based on a 10 km2 reference grid. Green and light orange colors show areas with no or very limited sealing, while red and dark red colors show highly to fully sealed grid cells (mainly urban areas).
The map shows the percentage of the average annual change in soil sealing for each of the rectangular 10 km x 10 km grid cells, over the 2009-2012 period
Soil is an important and often neglected element of the climate system. It is the second largest carbon store, or "sink", after the oceans. Restoring key ecosystems on land, and a sustainable use of the land in urban and rural areas, can help us mitigate and adapt to climate change.
