How much forest has Sarh lost?

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

- Forest in 2000
- 3,310 ha
- Forest in 2020

- Overall change
- +27 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Sarh stayed about the same size, at about 3,330 hectares: new forest grew on about 505 hectares, and about 477 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 Sarh lost since 2001?
There was very little forest around Sarh in 2000, about 2 hectares, and about 1 hectare 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 Sarh stayed about the same size, at about 3,330 hectares: new forest grew on about 505 hectares, and about 477 hectares were lost.
What is the tree count in Sarh?
Sarh has an estimated 92,448 trees across the 12.17 km² of land measured — 30.4% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Sarh need?
Sarh has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Sarh'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 Sarh; the tree count is an estimate derived from that cover.
