A recurring HN trope is people who don't know about a subject feel like they have to have an opinion on it anyway. Why do you believe it's very risky / in the hands of nature? Flooded plains (aka rice paddies) have been used for thousands of years; rice is a semiaquatic plant so it needs to be submerged, and paddies are designed to retain water to not be subject to the whims of nature.

Anyway, what alternative are you suggesting? Keep in mind it has to be scalable to feed billions and affordable.
