How many farms have you seen in the middle of a city?
OK, I realize that most of you aren't from the US, but anyone who's ever flown over the Great Plains (and many other areas, I would imagine) has seen circles like those. They are indeed farms. As R_Havell says, an irrigation system is anchored at the center of each circle, as explained above. It rotates about the anchor, watering as it goes, so you end up with crops growing in a nice circle. Admittedly, the first time I saw those from the air, I didn't know what they were either. They do look awfully interesting.
Also, those other things aren't mounds; they're depressions. Look at the shadows on the buildings.
