Forest gained and lost, 2000–2020

Forest in 2000: 3,650 ha
Forest in 2020: 3,970 ha
Overall change: +324 hamore forest than in 2000

Comparing satellite maps from 2000 and 2020, the forest around Goiânia grew from about 3,650 hectares to 3,970 hectares, a net gain of about 324 hectares (+8.9%). New forest grew on about 566 hectares, while 242 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.

New forest grew on about 566 hectares, while 242 hectares were lost.

What is the tree count in Goiânia?

Goiânia has an estimated 46,135 trees across the 12.56 km² of land measured — 14.7% tree cover, 15 percentage points short of the 30% tree-cover target set for this area.

How are Goiânia'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 St. Central; the tree count is an estimate derived from that cover.
