The Swiss Federal Government’s agricultural policy aims inter alia to provide agricultural ecosystem services, reduce environmental impacts, and increase the resilience of the agricultural sector. Combining the cultivation of trees with crops or grass – termed «agroforestry » – can contribute to achieving these goals without substantially limiting agricultural production. We identified the regions where environmental pressures (as defined by the Agricultural Environmental Objectives) occur, and where agroforestry systems can contribute to reducing these impacts. Our results are based on eleven national deficit maps for the environmental sectors of biodiversity, landscape, climate, air, water and soil, according to which three or more deficits occur simultaneously on 13.3 % of the utilised agricultural area (UAA). Converting these 13.3 % of UAA into agroforestry systems such as e.g. rows of trees in arable fields , short rotation trees and shade trees for animals, could offset up to 13 % of the agricultural sector‘s greenhouse-gas emissions. The use of these maps and the major potential offered by agroforestry systems will enable to develop strategies geared to local conditions and to environmental targets.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.

Tests carried out by Agroscope in the Valais region reveal that the Humagne Rouge grape variety yields better wines and is less susceptible to bunch shrivel when grapevines are not irrigated.

A natural antagonist of Drosophila suzukii, a parasitic wasp from its native range, is harmless to the native non-target species Drosophila melanogaster. This has been proven in trials in secured field cages in Switzerland.
