A recently completed research program (TREES) employing the global imaging capabilities of Earth-observing satellites provides updated information on the status of the world's humid tropical forest cover. Between 1990 and 1997, 5.8 ± 1.4 million hectares of humid tropical forest were lost each year, with a further 2.3 ± 0.7 million hectares of forest visibly degraded. These figures indicate that the global net rate of change in forest cover for the humid tropics is 23% lower than the generally…

Tropical forest cover change in the 1990s and options for future monitoring
TLDR
The Forest Resources Assessment 2000 deforestation statistics from countries are consistent with the satellite-based estimates in Asia and America, but are significantly different in Africa, highlighting the particular need for long-term capacity-building activities in this continent.
Carbon emissions from tropical deforestation and regrowth based on satellite observations for the 1980s and 1990s
TLDR
The results indicate that the net rate of tropical forest clearing increased ≈10% from the 1980s to 1990s, most notably in southeast Asia, in contrast to an 11% reduction reported by the FRA.
A contemporary assessment of change in humid tropical forests.
TLDR
Estimates of the contemporary global extent of deforestation, selective logging, and secondary regrowth in humid tropical forests are combined to highlight the enormous geographic extent of forest change throughout the humid tropics and the considerable limitations of the science and technology available for such a synthesis.
Determination of tropical deforestation rates and related carbon losses from 1990 to 2010
TLDR
It is shown that there was a gross loss of tropical forests in the 1990s and 2000s and that carbon loss rates did not change between the two last decades, reconciling recent low estimates of carbon emissions from tropical deforestation.
A long-term perspective on deforestation rates in the Brazilian Amazon
Abstract. Monitoring tropical forest cover is central to biodiversity preservation, terrestrial carbon stocks, essential ecosystem and climate functions, and ultimately, sustainable economic…
Aboveground Forest Biomass and the Global Carbon
  • Environmental Science
  • 2005
The long-term net flux of carbon between terrestrial ecosystems and the atmosphere has been dominated by two factors: changes in the area of forests and per hectare changes in forest biomass…
Tropical forest cover dynamics for Latin America using Earth observation data: a review covering the continental, regional, and local scale
The tropical forest cover has varied greatly over the last few decades. The rapid advance of agricultural crops and illegal clearings in natural areas has resulted in the conversion of the majority…
MAPPING TROPICAL DEFORESTATION IN CENTRAL AFRICA
TLDR
The annual clearance of the dense forest was significantly related to the rural population density, and there was a positive relationship between the dense Forest degraded during the 1980s–1990s and the degraded forest area in the 1980’s.
Accelerated deforestation in the humid tropics from the 1990s to the 2000s
TLDR
The estimates indicate a 62% acceleration in net deforestation in the humid tropics from the 1990s to the 2000s, contradicting a 25% reduction reported by the United Nations Food and Agriculture Organization Forest Resource Assessment.

Annual fluxes of carbon from deforestation and regrowth in the Brazilian Amazon
TLDR
The annual source of carbon from land-use change and fire approximately offsets the sink calculated for natural ecosystems in the region, so this large area of tropical forest is nearly balanced with respect to carbon, but has an interannual variability of ± 0.2 PgC yr-1.
Tropical Deforestation and Habitat Fragmentation in the Amazon: Satellite Data from 1978 to 1988
TLDR
Although this rate of deforestation is lower than previous estimates, the effect on biological diversity is greater and tropical forest habitat, severely affected with respect to biological diversity, increased.

Increased damage from fires in logged forests during droughts caused by El Niño
TLDR
The results support the hypothesis of positive feedback between logging and fire occurrence and significantly increased the risk of recurrent fire disasters by leaving huge amounts of dead flammable wood.

Recent patterns and mechanisms of carbon exchange by terrestrial ecosystems
TLDR
An overview of the current state of knowledge of global and regional patterns of carbon exchange by terrestrial ecosystems is provided, confirming that the terrestrial biosphere was largely neutral with respect to net carbon exchange during the 1980s, but became a net carbon sink in the 1990s.
