Biodiversity, the diversity of life at all scales, is a characteristic feature of our planet and a precondition for human life. However, only during the last two decades biodiversity has become an important research topic. Scientific projects deal with the measurement of biodiversity, the factors that affect biodiversity and with effects biodiversity itself has on ecosystems and other variables. The topography of Switzerland is very complex and the ecological conditions vary over small scales. This probably explains the large local biodiversity. Since human population pressure and economic activity are also particularly high in Switzerland, our country has a special responsibility to develop a comprehensive strategy for the conservation and sustainable use of biodiversity. At the same time, it could play a major role in global biodiversity policy.
A comparison of different methods of winter-wheat fertilisation with nitrogen showed that nitrogen surpluses can be significantly reduced by means of site-specific variable-rate nitrogen fertilisation.

Many tile drainage systems on arable land are in need of renewal. Cantons and stakeholders will now be given a decision-making tool enabling them to assess such areas in detail and to find sustainable solutions.
Ammonia emissions from the Swiss farming sector have scarcely declined over the past 20 years. This is because the factors leading to either an increase or decrease in emissions have for the most part cancelled each other out between 2000 and 2020.
