Deforestation · 2001–2025
Which has lost more forest, Kisangani or Mbuji-Mayi?
Kisangani has lost more: about 15,900 ha of forest within 10 km of its center from 2001 to 2025, against 25 ha around Mbuji-Mayi. 5,320 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: 2014, with 1,370 ha lost.
Worst year: 2004, with 6 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
Kisangani vs Mbuji-Mayi: your questions answered
Is Mbuji-Mayi cleaner than Kisangani?
On air quality, yes, right now: Mbuji-Mayi reads AQI 32 against 40, a gap of 8 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, Kisangani averaged AQI 43 against 52, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Kisangani and Mbuji-Mayi today?
The advice is the same for both today. Air quality is satisfactory for everyone. Kisangani reads AQI 40 and Mbuji-Mayi reads AQI 32.
Which has lost more forest, Kisangani or Mbuji-Mayi?
Kisangani has lost more: about 15,900 ha of forest within 10 km of its center from 2001 to 2025, against 25 ha around Mbuji-Mayi. 5,320 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Kisangani or Mbuji-Mayi?
Mbuji-Mayi has more tree cover: 26.8% of the land within 2 km of its center against 18.2% around Kisangani, or about 84,195 trees against 49,973. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Kisangani and Mbuji-Mayi need?
Kisangani needs about 32,400 more to reach its canopy target of 30%, and Mbuji-Mayi about 10,053 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Kisangani and Mbuji-Mayi 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 Kisangani vs Mbuji-Mayi 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 6, 2026 and Sep 9, 2026), and the forest figures are published yearly.
