Does anyone have an opinion, on the efficacy of a hypothetical UN legion building a "city" in an easily defensible location? Building an easily defensible city could solve the problem of marauding, and allow for a stable enough environment for sufficient infrastructure to allow local markets to flourish.

With such a "city", dislocated populations could have some place to go to and could provide the labor needed in that newly created "market". Humanitarian assistance would also be more effectually provided from facilities that have access to modern infrastructure (i.e. energy, potable and waste water management systems.)

That type of strategy could also make it easier for local security forces to maintain the domestic tranquility, and could leave the UN force freer to quell more serious disturbances as a rapid reaction force.
