FAO Forest Resources Assessment (FRA) module is now available
During FRA 1990,
FAO carried out a pan-tropical survey of forest cover changes based
on sample and remote sensing data. The main objectives of the survey
were to complement country information data and to provide consistent
and reliable detailed information on change processes for the period
1980-1990 at pan-tropical, regional and ecological zone levels.
117 sampling units covering 10% of the pan-tropical area were selected.
For each of them satellite imagery was acquired at two points in
time close to 1980 and 1990, and photo-interpreted with particular
attention to the recognition of changes between nine land cover
of the FRA 2000 remote sensing survey were to: monitor tropical
forest cover state and change for the past 20 years; evaluate current
trends at regional and higher levels; study the dynamics of change
in forest cover and identify the causes of deforestation; complement
existing country information by providing spatially and temporally
consistent data on forest state and change.
FRA data for
1980, 1990 and 2000 (including matrices, graphs and raster maps)
are now available on TEMS at the pan tropical, regional, sub-regional
and sampling unit levels. The land cover classification and a forest
cover change variable sheet provide more detailed information related
to the methodology and process used to undertake the survey. Links
to the FRA homepage and the FRA 2000 full report are available in
