How much forest has Abakaliki lost?
There was very little forest around Abakaliki in 2000, about 30 hectares, and about 7 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.

The worst year was 2018, when about 4 hectares of forest were lost.

Comparing satellite maps from 2000 and 2020, the forest around Abakaliki shrank from about 557 hectares to 494 hectares, a net loss of about 63 hectares (−11%). New forest grew on about 32 hectares, but 95 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 Abakaliki lost since 2001?

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 Abakaliki shrank from about 557 hectares to 494 hectares, a net loss of about 63 hectares (−11%). New forest grew on about 32 hectares, but 95 hectares were lost.
What is the tree count in Abakaliki?
Abakaliki has an estimated 39,270 trees across the 12.57 km² measured — 12.5% tree cover, 18 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Abakaliki need?
Abakaliki needs roughly 54,978 more trees to close a 18-point shortfall against its 30% tree-cover target — about 1,210 t of extra CO₂ absorbed per year once grown.
How are Abakaliki'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 Azuiyi Udene; the tree count is an estimate derived from that cover.
