Comparing satellite maps from 2000 and 2020, the forest around Musoma shrank from about 512 hectares to 427 hectares, a net loss of about 85 hectares (−17%). New forest grew on about 24 hectares, but 109 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.

Over the last 7 days, the CAMS air-quality model put Musoma's daily AQI at 50 on average, from 43 on Nov 6 to an hourly peak of 74 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 Musoma lost since 2001?
Since 2001, the area within 10 km of Musoma has lost about 43 hectares of forest (about 60 football pitches): 15% of the forest it had in 2000. Most of it (94%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations. Comparing satellite maps from 2000 and 2020, the forest around Musoma shrank from about 512 hectares to 427 hectares, a net loss of about 85 hectares (−17%). New forest grew on about 24 hectares, but 109 hectares were lost.
What is the tree count in Musoma?
Musoma has an estimated 55,607 trees across the 8.27 km² of land measured — 26.9% tree cover, 3 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Musoma need?
Musoma needs roughly 6,408 more trees to close a 3-point shortfall against its 30% tree-cover target — about 141.0 t of extra CO₂ absorbed per year once grown.
How are Musoma'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 Musoma; the tree count is an estimate derived from that cover.
