This year's grain production has been severely affected by natural disasters and the epidemic. The global food production has been affected to a certain extent,
Agree with you,
Further, In addition, rice is also the most important food crop to feed about half of the population
so the supply is correspondingly reduced, and the demand is relatively stable, which has caused the increase in food prices.
Some of the objective reasons that I think are directly or indirectly related to rising food prices:
1. The Covid-19 pandemic caused a record high and broke the food supply chain.
2. Climate change increases crop diseases, natural disasters, floods ...
3. The most serious forest fire in California or grasshopper accident in Ethiopia.
All disrupted agricultural output, disrupting the food supply chain.
