IOM’s warning links damaged housing and disrupted energy supplies to the risk that families who have already moved could be forced to leave again.

The International Organization for Migration has warned that damage to homes and attacks on energy infrastructure could trigger further displacement in Ukraine as winter approaches. The agency’s October 16 warning places the ability to live safely in a home at the centre of the humanitarian outlook, rather than treating electricity disruption as a problem separate from population movement.

The distinction matters because a return home is not necessarily the end of displacement risk. A family may have accommodation but still face conditions that make remaining there difficult or unsafe. The relevant question is not only whether a building exists, but whether it can support daily life through the conditions ahead.

A large displaced population and an uncertain return

IOM’s published warning puts the number of people internally displaced in Ukraine at nearly 3.6 million, with an estimated 3.8 million having returned to their places of origin. These figures describe different circumstances. They are not a forecast that all of those people will move again, and they should not be combined into a single predicted wave of departures.

According to Reuters’ October 16 reporting, IOM says people who returned within the preceding three months are the most likely to express an intention to leave again. An intention reported in a survey is a warning indicator, not a count of completed journeys.

The infrastructure problem reaches inside the home

Energy resilience has a household dimension as well as a national one. Restoring supply somewhere in a network does not establish that every building can use it, that a damaged home retains heat or that a household can afford the remaining costs of living there. The chain from energy availability to safe accommodation contains several separate requirements.

This makes the interaction between repair programmes important. A repaired building may still need reliable local services. A restored service may provide limited benefit to a home that remains uninhabitable. As an analytical matter, progress should be assessed across the combined conditions needed for daily life, rather than through a single national figure that cannot describe every community’s experience.

International commitments need to reach usable services

At the October 15–16 European Council, EU leaders condemned Russian attacks on Ukrainian civilians and critical infrastructure. Ahead of winter, they called for further support through the Ukraine Energy Support Fund, stronger regional energy cooperation and cross-border electricity interconnections. These are the leaders’ stated priorities; the summit statement does not establish that every proposed improvement has already been delivered.

That distinction between commitment and delivery is central to the winter outlook. Funding needs to become procurement, equipment, installation and functioning service. Each stage can have a different timetable. A financial announcement can therefore be important while still leaving an immediate gap between what has been promised and what a household or local service can actually use.

The useful measures of progress would distinguish those stages. Equipment committed is not the same as equipment operating. Restored capacity is not the same as uninterrupted availability under every condition. Clear reporting makes it easier to identify the remaining constraint without diminishing the value of work that has already been completed.

Funding gaps narrow the range of options

The Reuters report also says less than 7% of IOM’s 2026 Ukraine response plan was funded. That figure refers to the agency’s specified plan, not to the entirety of international support for Ukraine or every humanitarian programme operating in the country.

Where resources are scarce, the timing and selection of assistance become especially consequential. A small intervention completed before severe conditions arrive may be more useful than a larger one delivered after a household has already been forced to move. That is not an argument for abandoning longer-term reconstruction. It is a reason to connect the emergency timetable with the wider recovery effort instead of treating them as unrelated tasks.

Protecting choice is part of the response

Reducing displacement risk should not mean pressuring people to remain in unsafe conditions or treating every departure as a failure. The objective is to expand safe options. That can include support to remain where conditions permit, assistance to move when necessary and help for communities receiving people who have left elsewhere.

The circumstances of a family with reliable accommodation and income differ from those of someone facing damaged housing and few financial reserves. A broad population total cannot identify every such difference. Assistance is more likely to be useful when it is based on actual needs and constraints, with a way to reassess them as conditions change.

The winter test is habitability, not just restoration

The warning should focus attention on the point where infrastructure damage becomes a decision about whether a household can stay. National repair statistics remain important, but they should be considered alongside the condition of homes, access to local services and the practical options available to people already affected by displacement.

A stronger response would connect energy support, housing repairs and assistance for displaced people around that shared objective. Success would not be captured by one announcement or one restored asset. It would be reflected in more people having a genuinely safe and sustainable choice about where to live through the winter.
