Forests in Flux Forests worldwide are in a state of flux, with accelerating losses in some regions and gains in others. Hansen et al. (p. 850) examined global Landsat data at a 30-meter spatial resolution to characterize forest extent, loss, and gain from 2000 to 2012. Globally, 2.3 million square kilometers of forest were lost during the 12-year study period and 0.8 million square kilometers of new forest were gained. The tropics exhibited both the greatest losses and the greatest gains… 
Classifying drivers of global forest loss
TLDR
Using satellite imagery, a forest loss classification model is developed to determine a spatial attribution of forest disturbance to the dominant drivers of land cover and land use change over the period 2001 to 2015 and indicates that 27% of global forest loss can be attributed to deforestation through permanent land use changes for commodity production.
Doubling of annual forest carbon loss over the tropics during the early twenty-first century
Previous estimates of tropical forest carbon loss in the twenty-first century using satellite data typically focus on its magnitude, whereas regional loss trajectories and associated drivers are
Patterns of twenty‐first century forest loss across a global network of important sites for biodiversity
The contribution that remotely sensed satellite imagery could make to biodiversity monitoring is widely recognized, but remains largely unfulfilled at regional and global scales. Here, we use a
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.
Spatiotemporal changes in forest loss and its linkage to burned areas in China
Fire-induced forest loss has substantially increased worldwide over the last decade. In China, the connection between forest loss and frequent fires on a national scale remains largely unexplored. In
Large Uncertainty on Forest Area Change in the Early 21st Century among Widely Used Global Land Cover Datasets
TLDR
This study calls for the development of a more accurate database to support forest policies and to contribute to global actions against climate change.
High-resolution mapping of losses and gains of Earth’s tidal wetlands
Tidal wetlands are expected to respond dynamically to global environmental change, but the extent to which wetland losses have been offset by gains remains poorly understood. We developed a global
Forest Loss in Protected Areas and Intact Forest Landscapes: A Global Analysis
In spite of the high importance of forests, global forest loss has remained alarmingly high during the last decades. Forest loss at a global scale has been unveiled with increasingly finer spatial
Earth transformed: detailed mapping of global human modification from 1990 to 2017
Data on the extent, patterns, and trends of human land use are critically important to support global and national priorities for conservation and sustainable development. To inform these issues, we

Quantification of global gross forest cover loss
TLDR
A globally consistent methodology using satellite imagery was implemented to quantify gross forest cover loss (GFCL) from 2000 to 2005 and to compare GFCL among biomes, continents, and countries, finding the boreal biome experienced the largest area, followed by the humid tropical, dry tropical, and temperate biomes.
Benchmark map of forest carbon stocks in tropical regions across three continents
TLDR
A “benchmark” map of biomass carbon stocks over 2.5 billion ha of forests on three continents, encompassing all tropical forests, for the early 2000s is presented, which will be invaluable for REDD assessments at both project and national scales.
Mapping the World's Intact Forest Landscapes by Remote Sensing
Protection of large natural forest landscapes is a highly important task to help fulfill different international strategic initiatives to protect forest biodiversity, to reduce carbon emissions from
Land-use Pressure and a Transition to Forest-cover Loss in the Eastern United States
TLDR
The analysis shows that agricultural land use has continued to decline, and that this enables forest recovery; however, an important land-cover transition has occurred, from a mode of regional forest-cover gain to one of forest- cover loss caused by timber cutting cycles, urbanization, and other land-use demands.
Determination of Deforestation Rates of the World's Humid Tropical Forests
TLDR
The 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, indicating that the global net rate of change in forest cover for the humid tropics is 23% lower than the generally accepted rate.
Difficulties in tracking the long-term global trend in tropical forest area

  • Environmental Science

  • 2008
TLDR
It is shown that constructing a reliable trend is difficult and evidence for decline is unclear, within the limits of errors involved in making global estimates, and a better monitoring program is needed to give a more reliable trend.
Baseline Map of Carbon Emissions from Deforestation in Tropical Regions
TLDR
By systematically matching areas of forest loss with their carbon stocks before clearing, these results serve as a more accurate benchmark for monitoring global progress on reducing emissions from deforestation.
