Extreme weather events: possible impacts on agriculture in Germany:
Within the last 20 years extreme weather events have increased and led to an increasing variability of crop harvest from year to year. The observed extreme weather events, such as extreme winter frost, late frost, heat, draughts and wet conditions during seed or harvest period, showed a very complex spectrum causing different impacts.
Due to their frequently local occurrence, numerous extreme weather events cannot be detected on the basis of data from meteorological stations. Furthermore, adequately localized yield data are only available for cash crops e. g. cereals, oilseeds and sugar beets in order to assess the impacts of extreme weather events.
Consequently, losses can be quantified only ex post for these cash crops. The data base for impact analyses is lacking for many other plants and extreme weather events, which, however should be collected within already initiated research projects.
