- −2,340 haless forest than in 2000
Comparing satellite maps from 2000 and 2020, the forest around Impfondo shrank from about 25,400 hectares to 23,100 hectares, a net loss of about 2,340 hectares (−9.2%). New forest grew on about 40 hectares, but 2,380 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.
