- +915 hamore forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Sinch’ŏn-ŭp grew from about 1,720 hectares to 2,640 hectares, a net gain of about 915 hectares (+53%). New forest grew on about 920 hectares, while 6 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 are Sinch’ŏn-ŭp'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 Sinchon; the tree count is an estimate derived from that cover.
