Deforestation · 2001–2025
Which has lost more forest, Namangan or Tashkent?
Tashkent has lost more: about 55 ha of forest within 10 km of its center from 2001 to 2025, against under 1 ha around Namangan. 44 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.
No forest lost in any year.
Worst year: 2009, with 20 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.
More on the method on the About Airleaf page.
Frequently asked
Namangan vs Tashkent: your questions answered
Is Tashkent cleaner than Namangan?
On air quality, yes, right now: Tashkent reads AQI 37 against 49, a gap of 12 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, Tashkent averaged AQI 62 against 78, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Namangan and Tashkent today?
The advice is the same for both today. Air quality is satisfactory for everyone. Namangan reads AQI 49 and Tashkent reads AQI 37.
Which has lost more forest, Namangan or Tashkent?

Which has more trees, Namangan or Tashkent?
Tashkent has more tree cover: 16.0% of the land within 2 km of its center against 5.2% around Namangan, or about 50,165 trees against 16,304. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Namangan and Tashkent need?
Namangan needs about 77,756 more to reach its canopy target of 30%, and Tashkent about 43,894 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Namangan and Tashkent 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. Tashkent is read from a nearby ground station and Namangan 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 Namangan vs Tashkent 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 19, 2026 and Sep 17, 2026), and the forest figures are published yearly.
