Deforestation · 2001–2025
Which has lost more forest, Kananga or Mbuji-Mayi?
Kananga has lost more: about 3,520 ha of forest within 10 km of its center from 2001 to 2025, against 25 ha around Mbuji-Mayi. 902 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 351 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.

Kananga has more tree cover: 39.0% of the land within 2 km of its center against 26.8% around Mbuji-Mayi, or about 122,522 trees against 84,195. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Kananga and Mbuji-Mayi need?
Kananga needs about 0 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 Kananga 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 Kananga 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 19, 2026 and Sep 9, 2026), and the forest figures are published yearly.
