It's not the drought per se, it's input costs. Farmers are favouring crops that need less nitrogen and potassium.
Commodities have responded accordingly.
I hope the “riots” are in the form of voting.
20% of the remaining global supply comes from Iran, which has its own issues of drought and war.
The closure of the Strait of Hormuz is another big factor here as fertilizer prices have massively gone up. Diesel is more expensive too. Many crops this planting season (in the northern hemisphere) haven't been fertilized like they would normally and it's too late now so that will absolutely impact food prices later this year. The Global South will be disproportionately affected.
Lastly, the continued Russia-Ukraine war continues to impact Ukraine's wheat crops. Ukraine is (or was?) often called the "bread basket of Europe" because it was such a significant wheat grower and exporter.
We (the world) are genuinely going to have much more expensive food prices later this year and, in some places, there will be genuine famine.
