Deforestation · 2001–2025
Since 2001, Guinea-Bissau has lost about 212,000 hectares of forest (about 2,100 km²): 21% of the forest it had in 2000. Most of it (61%) was deforestation, forest cleared for good, mainly for farms, pasture and plantations.

Forest loss is slowing down: about 9,750 hectares a year in 2021–2025, down from 14,800 hectares a year in 2016–2020. The worst year was 2013, when about 19,600 hectares of forest were lost.
Also: storms, floods and other natural causes, towns and roads, mining and energy, logging, wildfires, unknown causes.
Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.

74.8% of Guinea-Bissau was forested as of 2024, against a 30% benchmark. That already clears the benchmark — the city reports above show where cover is still thin locally. Source: World Bank (FAO).

Clean-air buying guides
Picked by tested clean-air delivery rate (CADR), noise and running cost, from independent test labels. No brand pays to be listed.
Air purifiers that keep up with wildfire smoke and winter smog, ranked by verified smoke CADR, with the room each one clears on a smoky day.
Good HEPA air purifiers under $200 at the makers' own prices, compared on verified clean air, room size and what the filters cost each year.
NIOSH-approved N95 masks and P100 respirators for smog and smoke, and how to get the fit right. Cloth and surgical masks do little against PM2.5.
Frequently asked
Right now the 4 cities Airleaf measures in Guinea-Bissau average AQI 84 (moderate). The worst air is in Bafatá, at AQI 91, and the cleanest in Gabú, at AQI 76. None of the 4 measured cities is over AQI 100 today.
Bafatá, at AQI 91 (Moderate) on the US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.
Gabú, at AQI 76 (Moderate). Both lists rank current readings, from ground stations wherever Guinea-Bissau has at least three cities with one.
It depends on the city. 4 cities are Moderate. At the national average of AQI 84: Unusually sensitive people should consider limiting long outdoor exertion.
About 212,000 ha from 2001 to 2025, 21% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 130,000 ha of it was cleared for good, for farms, mines or towns.
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
