Deforestation · 2001–2025
Which has lost more forest, Korhogo or Yamoussoukro?
Yamoussoukro has lost more: about 991 ha of forest within 10 km of its center from 2001 to 2025, against under 1 ha around Korhogo. 990 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: 2001, with under 1 ha lost.
Worst year: 2022, with 171 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
Korhogo vs Yamoussoukro: your questions answered
Is Yamoussoukro cleaner than Korhogo?
On air quality, yes, right now: Yamoussoukro reads AQI 58 against 62, a gap of 4 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 6 days, on modeled daily averages, Yamoussoukro averaged AQI 46 against 60, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Korhogo and Yamoussoukro today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Korhogo reads AQI 62 and Yamoussoukro reads AQI 58.
Which has lost more forest, Korhogo or Yamoussoukro?
Yamoussoukro has lost more: about 991 ha of forest within 10 km of its center from 2001 to 2025, against under 1 ha around Korhogo. 990 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Korhogo or Yamoussoukro?
Yamoussoukro has more tree cover: 25.8% of the land within 2 km of its center against 11.5% around Korhogo, or about 78,946 trees against 35,839. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Korhogo and Yamoussoukro need?
Korhogo needs about 57,655 more to reach its canopy target of 30%, and Yamoussoukro about 12,852 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Korhogo and Yamoussoukro 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. Korhogo is read from a nearby ground station and Yamoussoukro 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 Korhogo vs Yamoussoukro 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 28, 2026 and Jan 26, 2026), and the forest figures are published yearly.
