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

Overall change
−2,540 haless forest than in 2000

Comparing satellite maps from 2000 and 2020, the forest around Igboho shrank from about 14,700 hectares to 12,100 hectares, a net loss of about 2,540 hectares (−17%). New forest grew on about 311 hectares, but 2,850 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.

How much forest has the area around Igboho lost since 2001?

New forest grew on about 311 hectares, but 2,850 hectares were lost.

What is the tree count in Igboho?

Igboho has an estimated 82,523 trees across the 12.51 km² of land measured — 26.4% tree cover, 4 percentage points short of the 30% tree-cover target set for this area.

How many more trees does Igboho need?

Igboho needs roughly 11,253 more trees to close a 4-point shortfall against its 30% tree-cover target — about 247.6 t of extra CO₂ absorbed per year once grown.

How are Igboho'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 Igboho 212104; the tree count is an estimate derived from that cover.
