SDG 15: Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
«[…] Deforestation and desertification – caused by human activities and climate change – pose major challenges to sustainable development […]»
Swiss target 15.3: Soil functions are sustainably conserved. Land use does not lead to degradation and where possible soils and their functionality are restored
Significance of the indicator
The indicator shows the proportion of sealed surfaces in the entire Swiss territory. When it is sealed, soil loses its natural function as habitat, reservoir and filter as well as the ability to transform and degrade substances. A decrease in this percentage is, therefore, a step towards sustainable development.
Help for interpretation
Sealed areas include buildings, greenhouses and areas covered with hard surfaces (asphalt, concrete, artificially laid gravel or stone surfaces, etc.).
This indicator cannot be compared at international level.
The indicator shows the percentage of sealed areas in Switzerland. Sealed areas include buildings (incl. Greenhouses) and areas covered with hard surfaces (asphalt, concrete, artificially laid gravel or stone surfaces, etc.). Data come from the Federal Statistical Office’s (FSO) land use statistics. These statistics provide information on land cover and use; they are compiled from aerial photographs taken by the Federal Office of Tophography (swisstopo), which are analysed by means of a sampling point network measuring 100 by 100 metres.
Swiss target 15.3: Soil functions are sustainably conserved. Land use does not lead to degradation and where possible soils and their functionality are restored.
International target 15.3: By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world.
