When it comes to rice is there really enough slack in the system to make a dent in the missing corn? My understanding is the amount of rice traded internationally is actually quite small (most is eaten in the same country it's grown in). I'm sure you/your tenants will get a great price for this year's crop, but realistically it seems the only place we'll be able to find slack in the US food system would be relaxing the ethanol mandate for one growing season (seems unlikely especially in an election year) or significantly reducing meat production. It's sounding like the second may already be happening, with many ranchers and feedlots thinning out their herds drastically this fall because the math shows they won't be able to afford to feed all their livestock at the prices corn is headed towards this winter.
In countries without a lot of meat consumption it's not clear what people will be able to do besides spend a lot more of their budgets on food or start missing a lot of meals.
