Experiences of the economic viability of herbicide tolerant crops (HT crops) were collected in a literature review from countries in which commercial cultivation is taking place. The results show that HT crops do not generally produce increased yields and no herbicide savings are effected in the long term. Economic benefits may be derived from the no-tillage system thereby made possible and from the simplification of chemical weed control. A direct transfer of results is only possible up to a point because of different structures and price levels in Switzerland. The cost and expense of coexistence measures were not included.
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.
