How much forest has Kahama lost?

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 Kahama grew from about 116 hectares to 135 hectares, a net gain of about 19 hectares (+16%). New forest grew on about 20 hectares, while under 1 hectare was 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 Kahama lost since 2001?

New forest grew on about 20 hectares, while under 1 hectare was lost.
What is the tree count in Kahama?
Kahama has an estimated 18,535 trees across the 12.57 km² measured — 5.9% tree cover, 24 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Kahama need?
Kahama needs roughly 75,712 more trees to close a 24-point shortfall against its 30% tree-cover target — about 1,666 t of extra CO₂ absorbed per year once grown.
How are Kahama'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 Kahama; the tree count is an estimate derived from that cover.
