Climate change progresses and especially for the agriculture there will be big challenges. In Austria, the important agriculture region Marchfeld will be affected by climate change. For this Master-Thesis regional climate models projecting the developments in the Marchfeld region up until 2100 are analysed. There is no doubt, that the temperature will increase. The Climate-models “Euro-Cordex” forecasts an increase of up to +5°C until the end of this century, with an emission-scenario RCP8.5. The precipitation will not change in a big manner. The frequency of extreme weather events will increase. European regions with temperatures +1-5°C compared to Marchfeld in the period (1981-2010) are identified and the agriculture is analysed in this area. Climate zones where temperature is 1-5°C higher than in Marchfeld, include southern (Italy, French, Spain) and south-eastern (Bulgaria, Romania, Turkey) Europe. Regions with +3°C are typical arable farming areas (Bulgaria, Romania, Po valley in north Italy). The cultivars are almost identical to the ones in Marchfeld. The higher temperatures the more important Durum-wheat and rice cultivars become. Permanent cultures and vegetable cultivation only play a minor role in those areas. In regions where temperatures are +4-5°C higher, the amount of permanent cultures of agricultural land rises. Fruits of subtropical climate are cultivated. Citrus-plants, Olive trees and Nut-trees become more important. Vineyards are common in each analysed region. In the future, agriculture in Marchfeld could cultivate arable cultures from warmer climates (e.g. Durum-Wheat, Rice). The most important vegetable cultivars (Asparagus, Onions, Carots) can continue to grow there in the future. Greenhouses are going to become more important to protect the vegetable production from extreme weather events. Citrus-cultivars will not be able to grow in Marchfeld in the future because they are sensitive to frost and wind. Olive trees can tolerate frost and the cultivation should be experimented in the future. With higher temperatures new plant pathogens will appear. Zero- and conservation tillage should be implemented to protect the high-quality soil (“Chernozem”). Smart irrigation techniques, which can save water, should be implemented.
