Probably not the worst prescription in the realm of pure theory, but who do you think should carry it out? Who would provide that strict and effective regulation of the use of semi-arid regions?

Obviously, nobody does either and thus the problem follows a rather natural trajectory. The way nature resolves such affairs is messy, of course.


A start would be if the normal migration into cities was guided and accelerated a bit, in order to reduce the population in settlements. The share of the population in the desertifying regions which considers itself nomads could probably be enticed to a seasonal migration pattern, in order to reduce its presence in the problematic regions.

Either way, improving the economy (relative unemployment, especially youth unemployment) in the cities along rivers or generally in humid areas, would help a lot.

Regulating semi-arid land use might be feasible through nature reservations, but I don't recall any impressive big game in the area, so this would at least initially look quite unconvincing.
One might probably outlaw certain kinds of livestock, too (the ones which damage vegetation the most. Goats are such problematic livestock elsewhere, but I'm not sure which livestock is being used in the region.)
