Urban rice field

I love coming across these little pockets of green nestled in amongst the chaotic jumble of shops and residential buildings.

Does one farmer own a whole string of these small plots or are they individually owned? Is the government subsidising them to grow not much rice for very little in return? Could be a zoning regulation thing. Maybe the farmer actually rents it from someone who isn't allowed to do anything else with it. Don't know.

Anyway, can't decide which of these is better so I'll put them both up.
