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 and soil provide vital resources to society such as food, feed, fuel, fibres and shelter. They also provide ecosystem services that support production functions, regulate the risk of natural hazards, and provide cultural and spiritual benefits. By using land, society alters and modifies the quantity and quality of these services, and the intrinsic potential for land benefits to mankind. To better manage its use of land and associated processes, society needs a systems (i.e. integrated) view on land. This briefing proposes an analytical framework that aims at developing a strategy for monitoring and integrated assessment of the state of land and its key resources.

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 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
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).
In this report, we have explored the notion of soil as an integral part of ecosystems and natural capital, and thus focused on the stock of the soil resource and the flows of valuable goods and services that can be derived from this stock. The concept of natural capital recognises soil as an asset that is of use and benefit to society (also called a 'productive' asset). Putting soil within the framework of the land system allows a connection to be made with governance, including soil resource efficiency.
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.
