and SEU leading to enhanced risk of crop failure and decrease in pasture quality . The risk is already moderately severe due to multiple crop failures in the past decade in WCE and Russia . Under high-end scenarios, heat and drought extremes are projected to become more frequent and widespread as early as mid-century . For present to moderate adaptation and at least up to 2.5°GWL, negative consequences are mostly in SEU . The transition from moderate to high risk is projected to happen around 2.7°C GWL when hazards and risk will become more persistent and widespread in other regions . This temperature increase will trigger shifts in agricultural zones, onset of early heat stress, losses in maize yield of up to 28% across EU- 28 and regional disparity in losses and gains in wheat, which are not able to offset losses across the continent . There will be also broader adverse impacts such as reduction of grassland biomass production for fodder, increases in weeds and reduction in pollination  . Combined with socioeconomic development, increased heat and drought stress, and reduced irrigation water availability, in SEU are projected to lead to abandonment of farmland . Around 4°C GWL, the risk is very high due to persistent heat and dry conditions  and the emergence of losses also in NEU which would be much higher without the assumed CO2 fertilisation .
