The development of an average farm of the ‘dairying/arable crops’ type (20 cows) in the plain area is simulated by means of a dynamic simulation model. As a result of milk price reductions, the farm will suffer continuous equity-capital losses if it maintains its current production. The present study investigates the alternative of specialisation in milk production, with the simultaneous construction of a new housing system for 45 cows, which scarcely leads to an improvement in the situation. Only major production-engineering optimisations such as a sharp increase in milk yield with constant pasturing or a conversion to full pasture would render the investment sustainable and allow for positive income development.
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.
