I was in another country, Eritrea, where I had a chance to chat with people who were explaining to me how they deal with land use. The traditional patterns have held up much better there, despite the horrible war they went through with Ethiopia a few decades back.
As far as I can see, the issues relate to land in some cases being useful at one time of the year but not at other times of the year, so that you have mutual rights and effectively what we would think of in our law as rights-of-way. All of these things are negotiated orally and retained in a non-written form, which is quite robust, but it's only robust as long as you're at peace with your neighbours and you don't have some outside authority driving people away. I think the destruction of that would have been very damaging there.
Does that describe a little bit of what's happening, or is it totally different?
