The influence of forest regrowth on biodiversity in alpine summer pastures was investigated as part of the joint research project AlpFUTUR. An evaluation of the target and indicator species of the agriculture- related environmental objectives (AEO species) for the alpine summer pastures shows that all regions of the Jura and the Alps are of equal importance for the conservation of AEO species. Forest regrowth up to 2021 was estimated on the basis of a model describing probabilities of land-use change. In the «North-Central Alps», the Tessin and parts of Graubünden, the percentage of forest regrowth can be as high as 50 %. For the conservation of AEO species, it is crucial for the species-rich meadows and pastures threatened by abandonment and forest regrowth to be identified locally, and for a locally adapted land-use concept to ensure that they remain under agricultural management. In the Jura mountains and in the «Northwestern Alps», the percentage of modelled forest regrowth is only between 1 and 5 %. Here, it is important to ensure extensive (i.e. low-input) land use on species-rich land, since intensification threatens the AEO species as much as abandonment and forest regrowth.
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.
