You can't grow rice where there isn't a proper water supply so much so that your field is basically a swamp until it's time to harvest. Meanwhile wheat and barley doesn't need much water to cultivate.

I don't think rice requires water? It just tolerates it fine, so it's useful for pest/weed control?

It requires water but not the same stagnant levels it used to. Modern cultivation is done with a series of inter connected Levees that allow the water to flow at lower levels than it used to be grown in.

You're thinking of something else, rice requires the land it's planted on to be under some centimeters of water. Just look for any image of a rice field. Only when it's ready to harvest that the field can be drier

EDIT: thanks for the replies, folks, those are some interesting rice facts!

There are varieties of rice that don’t require flooded fields. They’re called upland rice. They have issues with weeds and pest control that regular rice doesn’t have, but these varieties still manage to feed about a hundred million people.

Just because that's what you see on photos doesn't mean it's the only way to grow it, it just means it's the most efficient way. I had a quick look and found multiple sources corroborating GPs information: rice doesn't need to be under centimeters of water, it's only done to improve yield (by combatting weeds and pests).

Actually flooding rice drowns it.

Unfortunately the traditional system for growing rice has prevented realisation of plants' natural potential by transplanting them too late, by spacing them too closely, and by cutting off the oxygen supply to their roots by continuous flooding of paddies. SRI changes practices that are thousands of years old to bring out rice plants’ significant possibilities for greater yield.

AFAIK rice does not require that water, it's just that it can survive it, unlike most weeds.
