Okay, sure. That's a great question.
The map shows where most of them have gone, but most want to stay in areas close to the Donetsk and Luhansk. Many of them are Russian-speaking, and you find that in oblasts closest to the conflict zone. These are Russian-speaking areas. That close proximity allows them to cross back and forth to check on their properties, agricultural lands, and so on.
The problem is that many of these oblasts are becoming overwhelmed. As far back as 2014 the OSCE had reported that the capacity for NGOs, for civil society groups, and for oblast governments to support IDPs was already running out. I don't mean to be too harsh on the Ukrainian government, but they were woefully unprepared for this massive outflow of people. Probably any government would be, but it took a long time for them to get up to speed.
I can tell you that cities like Mariupol and Dnipropetrovsk, where a lot of the IDPs have gone, have basically said, “No vacancy, we can't possibly support any more”. It's important for two things to happen. One is for collective centres where IDPs live to continue to be supported. The other one is that they need to be found permanent housing. A lot of them are there with their children, and they brought very little with them, so this integration process needs to happen more.
The other thing I can tell you, aside from housing needs—I mentioned the lack of civil documentation—is that political rights are also going to be important if they're going to stay in areas controlled by the Ukrainian government. Elections are coming up, so they need to be part of that as well.
Finally, I think a lot has been said already about their mobility crossing back and forth over the contact line. Aside from being held up for hours or overnight by both sides at checkpoints, there's also the threat that if people are stationary along the contact line, with a lot of shelling happening, you're putting this massive number of people in danger. I believe over any given month as many as 100,000 civilians cross back and forth over the contact line.
Aside from the shelling, you also have the threat of land mines. Neither side has lived up to their full commitment to put signage to warn that there are land mines present. This is a responsibility they have to take upon themselves.
