Observational analysis reveals severe crop yield and revenue losses from drought in German agriculture, highlighting the necessity of spatially targeted climate adaptation strategies.

Key Points

To comprehensively evaluate and monetize the farm-level impacts of extreme weather events—including frost, heat, drought, and waterlogging—across critical phenological phases for major crops.
Analyzed 423,815 farm-level yield observations across Germany from 1995 to 2019.
Tracked weather impacts during critical phenological phases for winter wheat, winter barley, winter rapeseed, and grain maize.
Calculated spatially disaggregated economic revenue losses attributable to historical weather shocks.
Drought served as the primary driver of grain yield and financial losses, with a single drought day reducing winter wheat yields by up to 0.36%.
Summer drought in winter wheat resulted in an average annual revenue loss exceeding 23 million Euro across Germany from 1995 to 2019.
Waterlogging and frost caused lower aggregate economic damage than drought, though heat during flowering caused pronounced winter rapeseed yield losses in northern Germany.
