How much forest has Ilorin lost?
There was very little forest around Ilorin in 2000, about 7 hectares, and about 2 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here.

Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

Comparing satellite maps from 2000 and 2020, the forest around Ilorin stayed about the same size, at about 7,740 hectares: new forest grew on about 535 hectares, and about 461 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

Is it safe to exercise outside in Ilorin today?
At AQI 65 (Moderate): fine for most people; unusually sensitive people should take long or hard exercise easier. Windows: fine to open; close them if you are sensitive to pollution. Masks: not needed for most people. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Ilorin been like this week?
Over the last 7 days, the CAMS air-quality model put Ilorin's daily AQI at 82 on average, from 71 on Nov 10 to an hourly peak of 152 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
How much forest has the area around Ilorin lost since 2001?
There was very little forest around Ilorin in 2000, about 7 hectares, and about 2 hectares of it has been lost since. Only fairly dense woodland counts as forest in these maps, so scattered street and garden trees don't show up here. Comparing satellite maps from 2000 and 2020, the forest around Ilorin stayed about the same size, at about 7,740 hectares: new forest grew on about 535 hectares, and about 461 hectares were lost.
What is the tree count in Ilorin?
Ilorin has an estimated 8,168 trees across the 12.57 km² measured — 2.6% tree cover, 27 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Ilorin need?
Ilorin needs roughly 86,080 more trees to close a 27-point shortfall against its 30% tree-cover target — about 1,894 t of extra CO₂ absorbed per year once grown.
How are Ilorin's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Oko Erin; the tree count is an estimate derived from that cover.
