Comparing satellite maps from 2000 and 2020, the forest around Bissau shrank from about 6,670 hectares to 4,660 hectares, a net loss of about 2,010 hectares (−30%). New forest grew on about 59 hectares, but 2,060 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.

How is forest loss measured?
We use satellite maps from the University of Maryland (Hansen and colleagues) that show, for every 30 × 30 m patch of land on Earth, the year its trees were cut down, burned or died, from 2001 to 2025. We add up those patches within 10 km of the centre of Bissau, counting only places that were at least 30% covered by trees in 2000. The cause of each loss comes from a map made by the World Resources Institute and Google DeepMind. All figures are estimates.
