The pilot farm Mapraz was set up to give an answer to various questions related to the conversion of farms without livestock to organic farming. After twelve years of evaluation whereof during the last six years two crop rotation systems were compared (one with one year temporary ley -TL and one with two years of TL) the result shows that the average wheat yields are 8 % lower than the comparability index for wheat or matchable to the organic comparability index for field bean and oat. The contribution margins are between CHF 250.–/ha and CHF 670.–/ha lower than the comparability index in organic agriculture with livestock. The crop rotation system with 2 years of TL presents a better contribution margin (CHF 200.–/ha) and is less labour intensive (-2 hours/ha) than the crop rotation system with 1 year of TL.
Policies to reduce agricultural greenhouse gas emissions are more effective and more efficient if they are set at the regional level and not at the level of individual farms. This can help achieve climate targets.
Global food availability is expected to remain stable in the medium term. Food security challenges in Switzerland include the decline in agricultural land area per capita, higher incidence of extreme weather events and increased pressure from pests.
Different cultural backgrounds lead to different uptake of biodiversity agri-environmental schemes at the inner-Swiss French-German language border. Economic policy incentives could mitigate culture-driven behavioral differences.
