on these climate projections, the irrigation demand of Bavaria's agriculture is calculated in a model simulation. The … model results are subdivided into arable crops, vegetable crops and special crops. Studies on irrigation demand done in the … of the project. The model approach is based on the principle of Geisenheim irrigation management where soil and crop …

dryness and drought during different steps of the vegetation period and extreme heat in the blooming period lead to … considerable losses. In total the calculated sum of losses due to dryness, drought and heat are estimated to approximately 40 Mio … irrigation, followed by crop yield losses due to late frosts and soil wetness. For sugar beets losses could only be determined …

In this paper we consider a two periods model of cropping using irrigation. The farmer takes two kind of decisions, one … related to the level of investment in irrigation capacity and the other one to the irrigation level in each period. In the … period. Assuming a CARA utility function, we show that taxing the investment may entail an increase in preventive irrigation …
