Due to the war in Ukraine, wheat exports have declined worldwide. Yield fluctuations and losses due to climate change are additionally hampering the supply situation in individual regions of the world. As a result, wheat prices have risen sharply. In a recent study published in the journal Global Food Security, scientists argue that in the long term, wheat production must increase worldwide to compensate for the lack of exports. Alternatively, they say, the area on which wheat is grown must be increased. The study involved researchers from TU Munich, INRAE, Purdue University and Wageningen University, as well as the Leibniz-Centre for Agricultural Landscape Research (ZALF).
