The first surveys, and the size of the problem

The public conversation about demining tends to begin at the point where someone walks a field with a detector. The work before that is survey, and in early 2023 that was the binding activity.

Why survey comes first

Contamination is not uniform. A retreating force lays mines along particular lines; artillery leaves unexploded ordnance in specific patterns; a defended position has a different signature from a road that was simply crossed.

Non-technical survey uses testimony, records, aerial imagery and evidence of incidents to establish which land is likely contaminated and which is not. Getting that right multiplies the value of every clearance team, because effort spent on safe land is effort not spent on dangerous land.

The scale that emerged

By early 2023 it was clear that the affected area ran to tens of thousands of square kilometres, much of it productive farmland. That put Ukraine among the most mine-affected countries in the world within a single year.

Capacity from a small base

Ukraine began this period with a state emergency service experienced in legacy ordnance but sized for a normal country, and a handful of international operators. Everything since has been expansion: training programmes, imported machines, protective equipment and vehicles, funded by partner states.

The prioritisation question

With capacity far below need, sequencing decides outcomes. The rule that emerged is defensible: places where people live and walk first, then land that returns to production, then everything else. Schools, water sources and access roads before fields, and fields before forest.

It is a grim thing to have to rank, and doing it explicitly is better than doing it by accident.
