This is a refugee situation, and not an IDP situation, but I just remembered the sad fate of the Greek community in Abkhazia (Georgia?). How sometimes, even when there's national and/or international care, something just doesn't work out properly. A complex being, the human being...

St the beginning of 20th Century, Greek community (100.000 in 1989) settled down in Georgian coast, some of them around the port of Sujumi (14.000 in 1989). When the civil war started in 1992, the fled the country; they got the support of Greek government, that even provided planes to take them out of Sujumi (the capital of Abkhazia).

However, they didn't do so well in Greece. Most of them didn't speak Greek, didn't have more than distant relativesin Greece and hadn't perspectives. So a significative part of them came back to Abkhazia... To Abkhazia, a place that lost half of its population, that has a pro-Abjhaz nationalist attitude, that is siolated politically and economically (well, the Russian border is quite changeable in that sense...). A place in which in 1998, according to a report a read, the second economic source was selling to Turkey (I suppose that through informal channels) the marble from the tombs of the Georgian cementeries, having most of the Georgian community left the area.

"If you don't want a man unhappy politically, don't give him two sides to a question to worry him; give him one. Better yet, give him none." (Fahrenheit 451)
