Water shortages from climate change threaten wheat supplies


Wheat makes up about one fifth of our daily calories, and the demand for cereals is expected to grow significantly by 2050, especially in developing countries.

But without climate change mitigation, up to 60 per cent of the world’s wheat-growing areas will face severe water shortages, compared with 15 per cent today, according to a group of international scientists.

Under the Paris Agreement, the negative effects would seriously reduce these effects, but they would still double between 2041 and 2070 so future food security planning needs to include the risk of severe, sustained droughts.
