Deforestation · 2001–2025
Which has lost more forest, Gazipur or Rangpur?
Gazipur has lost more: about 30 ha of forest within 10 km of its center from 2001 to 2025, against 6 ha around Rangpur. 6 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: 2010, with 8 ha lost.
Worst year: 2007, with 1 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
Gazipur vs Rangpur: your questions answered
Is Gazipur cleaner than Rangpur?
On air quality, yes, right now: Gazipur reads AQI 112 against 138, a gap of 26 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, Rangpur averaged AQI 141 against 149, and it was the cleaner of the two on 3 of those days.
Is it safe to exercise outdoors in Gazipur and Rangpur today?
The advice is the same for both today. Sensitive groups should limit long or intense outdoor activity. Gazipur reads AQI 112 and Rangpur reads AQI 138.
Which has lost more forest, Gazipur or Rangpur?
Gazipur has lost more: about 30 ha of forest within 10 km of its center from 2001 to 2025, against 6 ha around Rangpur. 6 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Gazipur or Rangpur?
Gazipur has more tree cover: 61.7% of the land within 2 km of its center against 59.6% around Rangpur, or about 193,061 trees against 185,554. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Gazipur and Rangpur need?
Gazipur needs about 0 more to reach its canopy target of 35%, and Rangpur about 0 to reach 35%. The target starts at 30% of the land and rises where air quality is poor.
Are Gazipur and Rangpur 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. Gazipur is read from a nearby ground station and Rangpur 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 Gazipur vs Rangpur 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 (Oct 17, 2026 and Oct 20, 2026), and the forest figures are published yearly.
