Europe is set to suffer one of its sharpest ever declines in grain production as extreme weather and geopolitical tensions converge to pile pressure on farmers.

Searing temperatures have hit wheat yields and are expected to cut the region’s corn crop to the smallest in 19 years, while sunflower fields and livestock production have also suffered. At the same time, the Middle East conflict has pushed up fuel and fertilizer costs, slashing plantings across the continent earlier this year.

As a result, the European Union’s total grains output may shrink by more than 9% this year, according to lobby group Coceral. That would be the steepest annual drop in more than two decades, based on the European Union historical data. The June heat wave alone is likely to cost European grain farmers some €2 billion ($2.3 billion) in lost revenue, according to U.K. think tank, the Energy and Climate Intelligence Unit.
