Deforestation · 2001–2025
Which has lost more forest, Rîbniţa or Tiraspol?
Rîbniţa has lost more: about 100 ha of forest within 10 km of its center from 2001 to 2025, against 90 ha around Tiraspol. 2 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: 2020, with 15 ha lost.
Worst year: 2025, with 11 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.

Rîbniţa has lost more: about 100 ha of forest within 10 km of its center from 2001 to 2025, against 90 ha around Tiraspol. 2 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Rîbniţa or Tiraspol?
Rîbniţa has more tree cover: 39.0% of the land within 2 km of its center against 33.0% around Tiraspol, or about 121,664 trees against 102,740. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Rîbniţa and Tiraspol need?
Rîbniţa needs about 0 more to reach its canopy target of 30%, and Tiraspol about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Rîbniţa and Tiraspol 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 Rîbniţa vs Tiraspol 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 18, 2026 and Sep 18, 2026), and the forest figures are published yearly.
