Deforestation · 2001–2025
Which has lost more forest, Homyel' or Hrodna?
Homyel' has lost more: about 465 ha of forest within 10 km of its center from 2001 to 2025, against 292 ha around Hrodna. 200 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2018, with 70 ha lost.
Worst year: 2007, with 52 ha lost.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.

Frequently asked
Homyel' vs Hrodna: your questions answered
Is Homyel' cleaner than Hrodna?
On air quality, yes, right now: Homyel' reads AQI 34 against 58, a gap of 24 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 7 days, on modeled daily averages, Homyel' averaged AQI 34 against 63, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Homyel' and Hrodna today?
In Homyel', at AQI 34: Air quality is satisfactory for everyone. In Hrodna, at AQI 58: Unusually sensitive people should consider limiting long outdoor exertion.
Which has lost more forest, Homyel' or Hrodna?
Homyel' has lost more: about 465 ha of forest within 10 km of its center from 2001 to 2025, against 292 ha around Hrodna. 200 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Homyel' or Hrodna?
Hrodna has more tree cover: 32.1% of the land within 2 km of its center against 27.4% around Homyel', or about 99,736 trees against 85,994. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Homyel' and Hrodna need?
Homyel' needs about 8,160 more to reach its canopy target of 30%, and Hrodna about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Homyel' and Hrodna measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings are model estimates, with no ground station close enough to either. Nothing is adjusted for population, city limits or climate.
How often does the Homyel' vs Hrodna comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 13, 2026 and Aug 31, 2026), and the forest figures are published yearly.
