Abstract
Predicted climate change will affect agricultural water resources. Particularly vegetable crops will be concerned due to high water demand and high vulnerability to water scarcity. Present vegetable production already requires irrigation water. To assess future irrigation demand, the impact of climate change needs to be revealed region- and crop-specifically. For robust predictions, a wide range of scenarios has to be simulated using different climate models. The aim of this study is to evaluate the climate change impact on the water availability and irrigation demand of onion crops cultivated in a German model region. Focus is on crop-specific climatic water balance, considering soil characteristics and temperature-driven plant growth. Thus simulated irrigation demand differs between four climate models. However, in all scenarios climate parameters indicate increasing water demand until 2100.
