The Swiss food industry is made up of about 200 companies employing a total of 37,000 people and generating around 3.5 billion Swiss francs worth of turnover abroad. Furthermore, whilst the substitution of food production by energy production was considered in these scenarios, surplus land would provide further opportunities for the cultivation of bioenergy crops (6). If technology continues to progress at current rates then the area of agricultural land would need to decline substantially. Further warming projected by 2045-2075 would increase the likelihood of a second annual generation from 20% at present, to 70-100% (25). Changes in climatic conditions in this region are expected to particularly affect the production of spring-sown cereals such as maize. From research it was concluded that socio-economic assumptions have a much greater effect on the scenario results of future changes in agricultural production and land use then the climate scenarios (6). (2009), Ewert et al. This trend will continue with future warming. between pests and parasitoids or predators) could take place (1,2). The contribution of climate change just by itself is approximately a minor 1% (8). The yield increase caused by CO2 is, however, minor in comparison to long-term cultivation effects, and the positive effect on yield will be weakened by more strongly rising temperatures (16). However, agriculture is much more important in terms of area occupied (farmland and forest land cover approximately 90 % of the EU's land surface), and rural population and income (4). (1999); Smit and Skinner (2002); Torriani et al. Strategic designs and valuations of long-term investments in irrigation facilities and capacities have to simultaneously consider combinations of climate, market and institutional risks (20). (2007), Flückier and Rieder (1997), in: OcCC/ProClim- (2007), Luder and Moriz (2005), in: OcCC/ProClim- (2007), Finger and Schmid (2008), in: Finger et al. Analysis shows that the economic benefits of the adoption of irrigation in Swiss maize farming are not only sensitive to changes in climatic conditions but also to the development of output and water prices. Scenarios on future changes in agriculture largely depend on assumptions about technological development for future agricultural land use in Europe (6). (2018), Aluja et al. The expected economic benefits of adopting irrigation will be rather small in the future, particularly if lower crop prices due to market liberalization are taken into account. The productivity of meadows and the potential crop yield of many cultivated plants will increase as a result of the longer vegetation period, provided that the supply of water and nutrients is sufficient. In contrast, cereals are currently irrigated only to a very small extent (18). Such declines will not occur if there is a correspondingly large increase in the demand for agricultural goods, or if political decisions are taken either to reduce crop productivity through policies that encourage extensification or to accept widespread overproduction (6). The number of field workdays will increase and the decrease in soil water content will favour the use of bigger agricultural machines. Cultivation of higher altitudes to sustain livestock Thus, high altitude areas will gain in importance as ecological buffers for livestock husbandry (1,2,12). More frequent heavy precipitation events will aggravate soil erosion. The results suggest that current climate suitability for grain maize in Switzerland is mostly limited by sub-optimal temperatures, radiation and water stress, while climatic suitability for winter wheat is mostly limited through excess water, frost and heat stress. It is mainly located in alpine dry valley regions and used to the largest extent in grassland, vegetables, vine and fruit production. About one third of the agricultural land is located in the midlands. (2005), in: Alcamo et al. Agriculture accounts for only a small part of gross domestic production (GDP) in Europe, and it is considered that the overall vulnerability of the European economy to changes that affect agriculture is low (3). (2008), all in: Finger et al. The references below are cited in full in a separate map 'References'. Trend analyses for the period 1951–2000 have shown that on average plants bloom 21 days earlier, foliation takes place 15 days earlier and leaves change colour 9 days earlier, while the falling of leaves takes place 3 days later (14). Switzerland: Food production index (2004-2006 = 100): For that indicator, we provide data for Switzerland from 1961 to 2016. Provided that all soil nutrients are sufficiently available, an increase in the atmospheric CO2 concentration, in combination with slightly  higher temperatures and sufficient rainfall, means an increase in the potential yield of many agricultural crops. earlier hay harvest, irrigation of permanent grassland, adjustment of livestock, increased significance of high altitude areas for summer pasture, changes in the choice of tree species). Walnut Husk fly, an exotic species that first invaded the Mediterranean region, recently reached Switzerland, likely by crossing the Alpine divide (26). Maize may continue to benefit from increasing temperatures on the short term, but may also be increasingly limited by water scarcity as summer precipitation decreases. Although it is difficult to anticipate how this land would be used in the future, it seems that continued urban expansion, recreational areas (such as for horse riding) and forest land use would all be likely to take up at least some of the surplus. Pastures and meadows account for the largest part of the entire agricultural land. Plant products account for 47% of the output value of agricultural goods, dairy products for 27% and other animal products for 26% (12). Model results suggest that up to around 2050 grain maize yield in Switzerland could either increase or decrease depending largely on the choice of modelling approach and climate model projections, but also depending on local conditions. Faster plant development will result in harvest losses for cereals and grain legumes. Moreover, higher production and income risks might be covered with farm income diversification and with financial market instruments such as insurances or weather derivatives (21). (2011), Keller and Fuhrer (2004), in: Henne et al. The European population is expected to decline by about 8% over the period from 2000 to 2030 (7).

Europe is a major producer of biodiesel, accounting for 90% of the total production worldwide (10). is stopped (12). Weeds and insect attacks are expected to occur more often as will damages caused by extreme events. Political and economic forces may be of much more importance in the 2020–2050 time frame than the impact of climate change (13). The impact of climate change on the maize production at the eastern Swiss Plateau is expected to be small if simple adaptation options such as shifts in sowing dates and adjustments in the production intensity are taken into account. At the same time, a higher CO2 concentration reduces the protein content of wheat grains, which results in a reduction of the baking quality of the flour (12).
