We present an integrated modelling framework (IMF) to analyse climate change impacts on biophysical processes and farm management responses at the spatial resolution of 1km2. The IMF is applied to the Austrian agricultural sector for the period 2025-2040. The model results show that national agricultural producer surplus changes only marginally between -1% and +1% depending on the climate scenario. The regional results reveal that eastern cropland regions are more negatively affected than alpine grassland regions, which intensify production. This leads to changes in opportunity costs for agri-environmental programs, which calls for more targeted measures to increase efficiency and adaptation potential.
