Deforestation · 2001–2025
Which has lost more forest, Abidjan or Daloa?
Daloa has lost more: about 3,110 ha of forest within 10 km of its center from 2001 to 2025, against 891 ha around Abidjan. 3,110 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: 2009, with 119 ha lost.
Worst year: 2008, with 373 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
Abidjan vs Daloa: your questions answered
Is Daloa cleaner than Abidjan?
On air quality, yes, right now: Daloa reads AQI 30 against 39, a gap of 9 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, Abidjan averaged AQI 39 against 43, and it was the cleaner of the two on 5 of those days.
Is it safe to exercise outdoors in Abidjan and Daloa today?
The advice is the same for both today. Air quality is satisfactory for everyone. Abidjan reads AQI 39 and Daloa reads AQI 30.
Which has lost more forest, Abidjan or Daloa?
Daloa has lost more: about 3,110 ha of forest within 10 km of its center from 2001 to 2025, against 891 ha around Abidjan. 3,110 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Abidjan or Daloa?
Abidjan has more tree cover: 18.0% of the land within 2 km of its center against 17.2% around Daloa, or about 56,549 trees against 54,035. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Abidjan and Daloa need?
Abidjan needs about 37,699 more to reach its canopy target of 30%, and Daloa about 40,212 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Abidjan and Daloa 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. Abidjan is read from a nearby ground station and Daloa 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 Abidjan vs Daloa 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 22, 2026 and Aug 4, 2026), and the forest figures are published yearly.
