Forest gained and lost, 2000–2020

Forest in 2000: 1,430 ha
Forest in 2020: 1,110 ha
Overall change: −321 haless forest than in 2000

Comparing satellite maps from 2000 and 2020, the forest around Garanhuns shrank from about 1,430 hectares to 1,110 hectares, a net loss of about 321 hectares (−22%). New forest grew on about 24 hectares, but 345 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 Garanhuns'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 Magano; the tree count is an estimate derived from that cover.
