Deforestation · 2001–2025
Which has lost more forest, Daugavpils or Liepāja?
Daugavpils has lost more: about 2,090 ha of forest within 10 km of its center from 2001 to 2025, against 1,380 ha around Liepāja. 75 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: 2023, with 190 ha lost.
Worst year: 2022, with 153 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
Daugavpils vs Liepāja: your questions answered
Is Liepāja cleaner than Daugavpils?
On air quality, yes, right now: Liepāja reads AQI 29 against 93, a gap of 64 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. But over the past 7 days, on modeled daily averages, Daugavpils averaged AQI 35 against 36, and it was the cleaner of the two on 3 of those days.
Is it safe to exercise outdoors in Daugavpils and Liepāja today?
In Daugavpils, at AQI 93: Unusually sensitive people should consider limiting long outdoor exertion. In Liepāja, at AQI 29: Air quality is satisfactory for everyone.
Which has lost more forest, Daugavpils or Liepāja?
Daugavpils has lost more: about 2,090 ha of forest within 10 km of its center from 2001 to 2025, against 1,380 ha around Liepāja. 75 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Daugavpils or Liepāja?
Daugavpils has more tree cover: 25.1% of the land within 2 km of its center against 23.3% around Liepāja, or about 78,460 trees against 53,948. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Daugavpils and Liepāja need?
Daugavpils needs about 15,317 more to reach its canopy target of 30%, and Liepāja about 15,513 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Daugavpils and Liepāja 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. Liepāja is read from a nearby ground station and Daugavpils is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Daugavpils vs Liepāja 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 (Aug 5, 2026 and Sep 11, 2026), and the forest figures are published yearly.
