Whether it’s a failure or not depends on whether they’re living in yurts by choice because it’s their traditional way of living, or they’re doing it because it’s cheap and they can’t afford anything else. (There are probably also some sanitation issues—I don’t think most yurts have running water, so public infrastructure would have to make up the difference there.) And you do need some minimal qualifications for assessing that: talking to the people living in the yurts would be a good start.
