Deforestation is a primary contributor to climate change, [1][2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4][5] Greenhouse gases are emitted from deforestation ...
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Deforestation is the main land use change contributor to global warming, [126] as the destroyed trees release CO 2, and are not replaced by new trees, removing that carbon sink. [127] Between 2001 and 2018, 27% of deforestation was from permanent clearing to enable agricultural expansion for crops and livestock.
Deforestation by continent. In decades since 1990, South America and Africa have shown the greatest loss of forest area, with global net loss in the 2010s still about 60% of the 1990s value. [1] Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 ...
Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition." The forest is still there, but with fewer trees, or less species of trees, plants or ...
The moisture from the forests is important to the rainfall in Brazil, Paraguay, Argentina [45] Deforestation in the Amazon rainforest region was one of the main reason that cause the severe Drought of 2014–2015 in Brazil [46] [47] For the last three decades, the amount of carbon absorbed by the world's intact tropical forests has fallen ...
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused disturbances, such as timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. [1] It is distinguished from an old-growth forest (primary or primeval forest), which has ...
Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2][3] Climate change represents long-term changes in temperature and average weather patterns. [4][5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6]
