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.
In the short term, the wheat shortage could be made up by a coordinated release of wheat stocks, the authors say. In the longer term, however, other countries would have to fill the export gap, which could amount to as much as nine percent of global wheat exports. That would require an additional half-million tons of nitrogen fertilizer, the researchers calculated, and at already high fertilizer prices. Alternatively, the area under wheat cultivation would have to be increased by a total of eight percent.
