Sen, you may be able to answer this question that has been on my mind for a while. Are there still nomadic tribes in Africa? If so, what happens when they get "settled" by governments in one place? Surely some amount of movement is necessary to allow people to hunt and or farm in different areas and not exhaust the resources of one place. Don't get me wrong here, I am not saying people should be forced to wander but neither should they be forced to live in one place or by our own narrow standards. I

I am not even sure where I am going with this so probably just trying to put my thoughts in order. Is a certain amount of movement beneficial and, if so, should there be any borders to genuine nomads? Not that refugees are all in that situation but some may be. Yes? No? Food for thought at least I hope!
