A surge in farming costs along with the effects of climate change could leave an extra 100million people starving around the world, a study by Scots scientists found.
Researchers at Edinburgh University said up to a million more people could die in the coming decades due to malnutrition - chiefly due to high fertiliser prices.
They said the cost of fertilising crops had gone up threefold since 2021 - which could drive food prices 80 per cent higher than they were then.
Using computer modelling, the study found surging energy and fertiliser prices will have by far the greatest impact on food security in future.The war in Ukraine has led to the blockade of millions of tonnes of wheat, barley and corn - but reduced food exports from the region are less of a driver of food price rises than feared, the modelling indicated.
