Topic Biodiversity

Switzerland’s biodiversity is under pressure. Although incentive measures are having an effect locally, biodiversity remains in a poor state and continues to decline. A third of all species and half of all types of habitat in Switzerland are threatened. Occasional gains are not enough to make up for the losses caused mainly by a lack of land area, soil sealing, fragmentation, intensive use, and nitrogen and pesticide inputs. Subsidies that harm biodiversity exacerbate this negative trend. There is an urgent need for resolute action to preserve the services that biodiversity provides. Rich and resilient biodiversity also helps to mitigate climate change and its consequences.

Biodiversity: In brief

informs about the state of the environment and reveals the links between driving forces, pressures, environmental quality, impacts and responses.

Biodiversity policy

Rich biodiversity and its ecosystem services benefit not only society, but also the economy. This is why the Federal Constitution obliges the Confederation and the cantons to work together to safeguard the natural foundations of life for the long-term. The FOEN supports the Confederation in implementing a coherent biodiversity policy and in continuing to develop it further.
